Is Animal Testing Ever Justified?

The E.P.A. recently said it would move away from requiring the testing of potentially harmful chemicals on animals. Do you support the decision?

By Natalie Proulx

Find all our Student Opinion questions here.

On Sept. 10, the Environmental Protection Agency said it would move away from requiring the testing of potentially harmful chemicals on animals, a decision that was hailed by animal rights groups but criticized by environmentalists and researchers who said the practice was necessary to rigorously safeguard human health.

What are your thoughts on animal testing? Do you think it is ever justified? Why or why not?

In “ E.P.A. Says It Will Drastically Reduce Animal Testing ,” Mihir Zaveri, Mariel Padilla and Jaclyn Peiser write about the decision:

The E.P.A. Administrator Andrew Wheeler said the agency plans to reduce the amount of studies that involve mammal testing by 30 percent by 2025, and to eliminate the studies entirely by 2035, though some may still be approved on a case-by-case basis. The agency said it would also invest $4.25 million in projects at four universities and a medical center that are developing alternate ways of testing chemicals that do not involve animals. “We can protect human health and the environment by using cutting-edge, ethically sound science in our decision-making that efficiently and cost-effectively evaluates potential effects without animal testing,” Mr. Wheeler said in a memo announcing the changes. The E.P.A. has for decades required testing on a variety of animals — including rats, dogs, birds and fish — to gauge their toxicity before the chemicals can be bought, sold or used in the environment.

The article continues:

The practice of testing with animals has long prompted complex debates driven by passionate views on morality and scientific imperative. Reaction to Tuesday’s announcement was no different. “We are really excited as this has been something we’ve wanted for quite some time,” said Kitty Block, the president and chief executive of the Humane Society of the United States, an animal protection organization. “The alternatives are the future. They’re more efficient and save lives.” Kathleen Conlee, the vice president of animal research issues at the Humane Society, said the E.P.A.’s move is “broad-sweeping and significant.” “This is the first time a government agency has made such a commitment and timelined its specific goals along the way,” Ms. Conlee said. “There’s been a lot of positive action among other federal agencies, but we want to see all government agencies take this step.” Tracey Woodruff, a professor at the University of California, San Francisco’s school of medicine, said current alternatives to animal testing are somewhat useful. But Dr. Woodruff, who worked at the E.P.A. from 1994 to 2007, said only animal testing — a process honed over decades — was robust enough to gauge chemicals’ impacts on people of various ages, genetics and health backgrounds. “I definitely think we should be investing more in this research,” she said, referring to alternative testing. “But it’s really not ready for making decisions yet — at least the way that E.P.A. is making decisions.” Jennifer Sass, a senior scientist at Natural Resources Defense Council, an environmental advocacy group, said she was very concerned by the announcement. Dr. Sass said animals were still necessary to study chronic conditions, like cancer and infertility. Cells in a petri dish cannot yet replace whole living systems, she said. “The E.P.A.’s deadline is arbitrary,” Dr. Sass said. “Our interest isn’t in speed, it’s getting it right. We want proper animal testing because we don’t want harmful chemicals to end up in our food, air and water.”

Students, read the entire article, then tell us:

Do you support the decision by the E.P.A. to move away from requiring the testing of potentially harmful chemicals on animals? Or do you think animal testing is still necessary to regulate harmful substances that can have adverse effects on humans?

How important is it to you that the toxicity of chemicals and other environmental contaminants is rigorously studied and regulated? Why? Do you think not testing on animals hinders those efforts?

The Food and Drug Administration, the National Institutes of Health and the Department of Veterans Affairs are among the government agencies that still rely on animal testing. Do you think animal testing is important in these sectors or any others? Why or why not?

Do you think animal testing is ever justified? If so, what should be the criteria for when, how and on what animals testing is done?

Animal Testing is Unethical, Unreliable and Unnecessary

Every year, 100 million animals sit in U.S laboratories caged and waiting to be burned, abused, and infected (Madhusree 1). The test subjects have few rights, protective services, or liberties.

She focuses on it, and sees a soaked dog, whose fur is severely matted, and covered in mud. Its tail had no wag, and it was so […]

Medical Animal Testing should be Banned

Medical animal testing should be banned for there being other humane testing methods that exist.

3. Animal Testing Essay Strategies: Argumentative Vs. Persuasive

Argumentative and persuasive essays on animal testing might seem somewhat similar. Here, we will describe the differences between these two types.

Argumentative Essay

An argumentative essay’s primary purpose is to convince the audience that your position is valid and worth attention.

• It requires profound research. You need to study the terminology and updates while exploring the issue.
• Its main bases are logic and evidence. Avoid emotional appeals even if they make your arguments sound stronger.
• It implies research of both sides. You will need to include an opposing argument and show its relevance.

Persuasive Essay

A persuasive essay convinces its audience using both facts and emotional response of the readers to prove one’s opinion.

• It is less formal. The tone is more relaxed. Choose facts that instantly appeal to your audience.
• Its primary basis is opinion. You will rely on the choice of words and strong arguments rather than on evidence.
• It focuses on one perspective. You have to convince readers that your way of thinking is the only option. Reviewing other positions is optional.

Now that you know the differences, we will look at each type. Here, we will explain how to prepare for writing and create an animal-testing argumentative essay outline.

What Is Animal Testing Argumentative Essay About?

An animal testing argumentative essay discusses the pros and cons of animal testing giving preference to one of the sides. You should state whether animal testing is necessary in your thesis and provide at least two arguments to support your claim.

⚖️ Animal Testing Essay: For & Against

Here, you will find the pros and cons of animal testing . You can use these arguments in argumentative and persuasive essays.

I. Arguments FOR Animal Testing

Here is why animal testing should be allowed:

• Many life-saving medicines rely on animal testing . According to the California Biomedical Association, animal research helped almost every medical breakthrough in the last century . Millions of human lives depend on animal testing. It helps treat breast cancer, tuberculosis, leukemia, and many others.
• There is no alternative to testing vaccines . Scientists needed animal testing to ensure that a vaccine doesn’t make a virus more dangerous. During the global pandemic of 2020, researchers used genetically modified mice to develop vaccines. There was no other way to ensure people’s safety.
• Animal testing prevents risking lives of human volunteers . If we test medicine or cosmetical products on toxicity, we can’t use people. Human trials also possess risks of side effects, but it could be worse without animal testing.
• It ensures the safety of the products we use . China does not even allow to put cosmetical products on the market before animal testing. We use more and more cosmetical products every day. There are more and more of them on the market. That is why we need to ensure that every product we use is safe for us.
• We need animal testing to make drugs for animals as well . Scientists use animal testing to develop medicines, vaccines, and medical devices.

II. Arguments AGAINST Animal Testing

The reasons why animal testing should be stopped:

• Not all of the testing results apply to people . Many anatomic, cellular, and metabolic differences make animals poor models for us. So some drugs that pass animal testing can eventually fail on people.
• There are alternative testing methods . Skin-producing technologies such as tissue bioprinting and human skin cells growth can replace animal testing. Of course, it is not possible for all the products, but these technologies can significantly reduce the use of animals.
• It does not guarantee 100% safety . Human bodies might react differently to the same ingredients. When drugs do not show any side effects or harmful consequences on animals, they still might be dangerous for humans.
• The demand for cruelty-free products increases . People know about the inhumanity of animal testing and choose to buy cruelty-free products. Politicians are also concerned and take measures against animal testing. European Union, Australia, and South Korea banned cosmetics tested on animals. That is why cosmetical brands give up animal testing and switch to other options.
• Inhumane treatment and bad conditions . Animals suffer from food and water deprivation, inflicted burns and other wounds, and CO2 asphyxiation. Also, many of them have their eyes open for hours to test cosmetic products. Animals deserve ethical treatment as they cannot protect themselves from humans.

Should Animal Testing Be Banned Essay

As technological progress moves on, we need to move on too. Some practices that were considered normal should be reviewed in the 21st century. We need to choose animal welfare and moral standards over inhumanity. Animal testing should be banned because it is cruel, expensive, and inefficient.

Animals suffer when scientists use them as test models. Some live in small cages and do not have enough space for motion. Others are forced to eat or drink something unnatural for them. It is common for animals to experience pain because of skin and eye burns, itching, or other side effects in the worst cases. For example, during the Draize test, researchers put chemicals into rabbits' eyes to see the reaction.

Keeping and breeding animals need money. It implies costs for space, food, and other maintenance expenses. As animal tests are not always reliable and need several attempts, the price for developing a successful drug can exceed one billion dollars. Every time you buy a pill or a cosmetic product tested on animals, you pay for animal testing.

Animal testing does not guarantee identical results for humans in most cases. The failure rate for animal testing is higher than 95%. There are also many controversies because the reactions of animals and people to certain ingredients can be opposite. For example, penicillin can kill guinea pigs but helps people. Aspirin is dangerous for pets but relieves human headaches.

To put it all together, animal testing is immoral in the 21st century. It is inhuman, not accurate, and pricey to the companies. It would be better if they invested the money in new technologies to replace animal experimentation. All in all, we pay for these products as customers. We have a right to choose whether or not we want them to be tested on animals.

Animals Testing Essay - Model Answer

Issues related to animal experimentation are frequently discussed these days, particularly in the media. It is often said that animals should not be used in testing because it is cruel and unnecessary. This essay will examine the arguments for and against animal testing. 

On the one hand, the people who support these experiments say that we must do tests on animals. For instance, many famous lifesaving drugs were invented in this way, and animal experiments may help us to find more cures in the future. Indeed, possibly even a cure for cancer and AIDS. Furthermore, the animals which are used are not usually wild but are bred especially for experiments. Therefore, they believe it is not true that animal experiments are responsible for reducing the number of wild animals on the planet. 

On the other hand, others feel that there are good arguments against this. First and foremost, animal experiments are unkind and cause animals a lot of pain. In addition, they feel that many tests are not really important, and in fact animals are not only used to test new medicines but also new cosmetics, which could be tested on humans instead. Another issue is that sometimes an experiment on animals gives us the wrong result because animals’ bodies are not exactly the same as our own. As a consequence, this testing may not be providing the safety that its proponents claim.

In conclusion, I am of the opinion, on balance, that the benefits do not outweigh the disadvantages, and testing on animals should not continue. Although it may improve the lives of humans, it is not fair that animals should suffer in order to achieve this.

(Words 278)

This animal testing essay would achieve a high score.

It fully answers all parts of the task - explaining the arguments ' for ' in the first paragraph and the arguments ' against ' in the next. Conclusions are then drawn with the writer giving their opinion in the conclusion.

It is thus very clearly organised, with each body paragraph having a central idea .

Ideas are also extended and supported by the use of reasons and some examples or further clarification. No ideas are left unclear or unexplained.

There is also some good topic related vocabulary in the animal testing essay such as 'life saving drugs ' and 'bred ' and a mix of complex sentences , such as adverbial clauses :

'Although it may improve the lives of humans, it is not fair that animals should suffer in order to achieve this'.

Noun clauses :

'...they feel that many tests are not really important'.

And relative clauses :

'...the animals which are used are not usually wild... '

Transitions are also used effectively to ensure there is good coherence and cohesion . For example, ' On the other hand.. ' indicates a change to discuss the contrasting ideas, and ' Therefore... " and ' As a consequence..' are used to give results.

The ethics of animal experimentation.

Many medical research institutions make use of non-human animals as test subjects. Animals may be subject to experimentation or modified into conditions useful for gaining knowledge about human disease or for testing potential human treatments. Because animals as distant from humans as mice and rats share many physiological and genetic similarities with humans, animal experimentation can be tremendously helpful for furthering medical science.

However, there is an ongoing debate about the ethics of animal experimentation. Some people argue that all animal experimentation should end because it is wrong to treat animals merely as tools for furthering knowledge. According to this point of view, an animal should have as much right as a human being to live out a full life, free of pain and suffering. Others argue that while it is wrong to unnecessarily abuse animals, animal experimentation must continue because of the enormous scientific resource that animal models provide. Proponents of continued animal experimentation often also point out that progress can still be made to improve the conditions of laboratory animals and they fully support efforts to improve living conditions in laboratories, to use anesthesia appropriately, and to require trained personnel to handle animals.

On closer scrutiny, there exists a wide range of positions on the debate over the ethics of animal testing. The two views mentioned above represent two common positions at the opposing ends of the spectrum. Others endorse a view closer to the middle of the spectrum. Usually, this middle view accepts experimentation on some, but not all, animals and aims to avoid unnecessary use of animals in scientific research by pursuing alternatives to animal testing.

The following sections briefly outline a few of the arguments for and against animal experimentation. They do not represent every possible argument, or even necessarily the best arguments. They also do not necessarily reflect the views of the HOPES team. They are simply our effort to review and raise awareness of the underlying issues.

• The Case Against Animal Experimentation
• The Case For Animal Experimentation
• A Middle Ground

The Case Against Animal Experimentation ^

An important part of the debate over animal rights centers on the question of the moral status of an animal. Most people agree that animals have at least some moral status – that is why it is wrong to abuse pets or needlessly hurt other animals. This alone represents a shift from a past view where animals had no moral status and treating an animal well was more about maintaining human standards of dignity than respecting any innate rights of the animal. In modern times, the question has shifted from whether animals have moral status to how much moral status they have and what rights come with that status.

The strongest pro animal rights answer to this question would be that non-human animals have exactly the same moral status as humans and are entitled to equal treatment. The ethicists who endorse this position do not mean that animals are entitled to the very same treatment as humans; arguing that animals should have the right to vote or hold office is clearly absurd. The claim is that animals should be afforded the same level of respectful treatment as humans; in short, we should not have the right to kill animals, force them into our service, or otherwise treat them merely as means to further our own goals.

One common form of this argument claims that moral status comes from the capacity to suffer or to enjoy life. In respect to his capacity, many animals are no different than humans. They can feel pain and experience pleasure. Therefore, they should have the same moral status and deserve equal treatment.

Supporters of this type of argument frequently claim that granting animals less moral status than humans is just a form of prejudice called “speciesism.” We have an innate tendency, they say, to consider the human species more morally relevant merely because it is the group to which we belong. However, we look upon past examples of this behavior as morally condemnable. Being of a particular race or gender does not give one any grounds for declaring outsiders to be of a lower moral status. Many animal rights advocates argue similarly—that just because we are human is not sufficient grounds to declare animals less morally significant.

The Case For Animal Experimentation ^

Defenders of animal experimentation usually argue that animals cannot be considered morally equal to humans. They generally use this claim as the cornerstone of an argument that the benefits to humans from animal experimentation outweigh or “make up for” the harm done to animals. The first step in making that argument is to show that humans are more important than animals. Below, I will outline one of the more common arguments used to reach this conclusion.

Some philosophers advocate the idea of a moral community. Roughly speaking, this is a group of individuals who all share certain traits in common. By sharing these traits, they belong to a particular moral community and thus take on certain responsibilities toward each other and assume specific rights. For example, in most human moral communities all individuals have the right to make independent decisions and live autonomous lives – and with that right comes the responsibility to respect others’ independence.

Although a moral community could theoretically include animals, it frequently does not. The human moral community, for instance, is often characterized by a capacity to manipulate abstract concepts and by personal autonomy. Since most animals do not have the cognitive capabilities of humans and also do not seem to possess full autonomy (animals do not rationally choose to pursue specific life goals), they are not included in the moral community. Once animals have been excluded from the moral community, humans have only a limited obligation towards them; on this argument, we certainly would not need to grant animals all normal human rights.

If animals do not have the same rights as humans, it becomes permissible to use them for research purposes. Under this view, the ways in which experimentation might harm the animal are less morally significant than the potential human benefits from the research.

One problem with this type of argument is that many humans themselves do not actually fulfill the criteria for belonging to the human moral community. Both infants and the mentally handicapped frequently lack complex cognitive capacities, full autonomy, or even both of these traits. Are those individuals outside the human moral community? Do they lack fundamental human rights and should we use them for experimentation? One philosophical position actually accepts those consequences and argues that those humans have the exact same rights (or lack of rights) as non-human animals. However, most people are uncomfortable with that scenario and some philosophers have put forth a variety of reasons to include all humans in the human moral community. A common way to “return” excluded individuals to the human moral community is to note how close these individuals come to meeting the criteria. In fact, some of them (the infants) will surely meet all of the criteria in the future. With that in mind, the argument runs, it is best practice to act charitably and treat all humans as part of the moral community.

In summary, defenders of animal experimentation argue that humans have higher moral status than animals and fundamental rights that animals lack. Accordingly, potential animal rights violations are outweighed by the greater human benefits of animal research.

A Middle Ground ^

There is a middle ground for those who feel uncomfortable with animal experimentation, but believe that in some circumstances the good arising out of experimentation does outweigh harm to the animal. Proponents of the middle ground position usually advocate a few basic principals that they believe should always be followed in animal research.

One principle calls for the preferential research use of less complex organisms whenever possible. For example bacteria , fruit flies, and plants would be preferred over mammals. This reflects a belief in a hierarchy of moral standing with more complex animals at the top and microorganisms and plants at the bottom. A philosophical grounding for this sort of hierarchy is the “moral worth as richness of life” model. This point of view suggests that more complicated organisms have richer, more fulfilling lives and that it is the richness of the life that actually correlates with moral worth.

Another principle is to reduce animal use as far as possible in any given study. Extensive literature searches, for instance, can ensure that experiments are not unnecessarily replicated and can ensure that animal models are only used to obtain information not already available in the scientific community. Another way to reduce animal use is to ensure that studies are conducted according to the highest standards and that all information collected will be useable. Providing high quality, disease-free environments for the animals will help ensure that every animal counts. Additionally, well designed studies and appropriate statistical analysis of data can minimize the number of animals required for statistically significant results.

A third principle is to ensure the best possible treatment of the animals used in a study. This means reducing pain and suffering as much as possible. When appropriate, anesthesia should be used; additionally, studies should have the earliest possible endpoints after which animals who will subsequently experience disease or suffering can be euthanized. Also, anyone who handles the animals should be properly trained.

The “bottom line” for the middle ground position is that animal experimentation should be avoided whenever possible in favor of alternative research strategies.

Animal experimentation is widely used around the world for the identification of the root causes of various diseases in humans and animals and for exploring treatment options. Among the several animal species, rats, mice and purpose-bred birds comprise almost 90% of the animals that are used for research purpose. However, growing awareness of the sentience of animals and their experience of pain and suffering has led to strong opposition to animal research among many scientists and the general public. In addition, the usefulness of extrapolating animal data to humans has been questioned. This has led to Ethical Committees’ adoption of the ‘four Rs’ principles (Reduction, Refinement, Replacement and Responsibility) as a guide when making decisions regarding animal experimentation. Some of the essential considerations for humane animal experimentation are presented in this review along with the requirement for investigator training. Due to the ethical issues surrounding the use of animals in experimentation, their use is declining in those research areas where alternative in vitro or in silico methods are available. However, so far it has not been possible to dispense with experimental animals completely and further research is needed to provide a road map to robust alternatives before their use can be fully discontinued.

Animal model-based research has been performed for a very long time. Ever since the 5 th century B.C., reports of experiments involving animals have been documented, but an increase in the frequency of their utilization has been observed since the 19 th century [ 1 ]. Most institutions for medical research around the world use non-human animals as experimental subjects [ 2 ]. Such animals might be used for research experimentations to gain a better understanding of human diseases or for exploring potential treatment options [ 2 ]. Even those animals that are evolutionarily quite distant from humans, such as Drosophila melanogaster , Zebrafish ( Danio rerio ) and Caenorhabditis elegans , share physiological and genetic similarities with human beings [ 2 ]; therefore animal experimentation can be of great help for the advancement of medical science [ 2 ].

For animal experimentation, the major assumption is that the animal research will be of benefit to humans. There are many reasons that highlight the significance of animal use in biomedical research. One of the major reasons is that animals and humans share the same biological processes. In addition, vertebrates have many anatomical similarities (all vertebrates have lungs, a heart, kidneys, liver and other organs) [ 3 ]. Therefore, these similarities make certain animals more suitable for experiments and for providing basic training to young researchers and students in different fields of biological and biomedical sciences [ 3 ]. Certain animals are susceptible to various health problems that are similar to human diseases such as diabetes, cancer and heart disease [ 4 ]. Furthermore, there are genetically modified animals that are used to obtain pathological phenotypes [ 5 ]. A significant benefit of animal experimentation is that test species can be chosen that have a much shorter life cycle than humans. Therefore, animal models can be studied throughout their life span and for several successive generations, an essential element for the understanding of disease progression along with its interaction with the whole organism throughout its lifetime [ 6 ].

Animal models often play a critical role in helping researchers who are exploring the efficacy and safety of potential medical treatments and drugs. They help to identify any dangerous or undesired side effects, such as birth defects, infertility, toxicity, liver damage or any potential carcinogenic effects [ 7 ]. Currently, U.S. Federal law, for example, requires that non-human animal research is used to demonstrate the efficacy and safety of any new treatment options before proceeding to trials on humans [ 8 ]. Of course, it is not only humans benefit from this research and testing, since many of the drugs and treatments that are developed for humans are routinely used in veterinary clinics, which help animals live longer and healthier lives [ 4 ].

COVID-19 AND THE NEED FOR ANIMAL MODELS

When COVID-19 struck, there was a desperate need for research on the disease, its effects on the brain and body and on the development of new treatments for patients with the disease. Early in the disease it was noticed that those with the disease suffered a loss of smell and taste, as well as neurological and psychiatric symptoms, some of which lasted long after the patients had “survived” the disease [ 9-15 ]. As soon as the pandemic started, there was a search for appropriate animal models in which to study this unknown disease [ 16 , 17 ]. While genetically modified mice and rats are the basic animal models for neurological and immunological research [ 18 , 19 ] the need to understand COVID-19 led to a range of animal models; from fruit flies [ 20 ] and Zebrafish [ 21 ] to large mammals [ 22 , 23 ] and primates [ 24 , 25 ]. And it was just not one animal model that was needed, but many, because different aspects of the disease are best studied in different animal models [ 16 , 25 , 26 ]. There is also a need to study the transmission pathways of the zoonosis: where does it come from, what are the animal hosts and how is it transferred to humans [ 27 ]?

There has been a need for animal models for understanding the pathophysiology of COVID-19 [ 28 ], for studying the mechanisms of transmission of the disease [ 16 ], for studying its neurobiology [ 29 , 30 ] and for developing new vaccines [ 31 ]. The sudden onset of the COVID-19 pandemic has highlighted the fact that animal research is necessary, and that the curtailment of such research has serious consequences for the health of both humans and animals, both wild and domestic [ 32 ] As highlighted by Adhikary et al. [ 22 ] and Genzel et al. [ 33 ] the coronavirus has made clear the necessity for animal research and the danger in surviving future such pandemics if animal research is not fully supported. Genzel et al. [ 33 ], in particular, take issue with the proposal for a European ban on animal testing. Finally, there is a danger in bypassing animal research in developing new vaccines for diseases such as COVID-19 [ 34 ]. The purpose of this paper is to show that, while animal research is necessary for the health of both humans and animals, there is a need to carry out such experimentation in a controlled and humane manner. The use of alternatives to animal research such as cultured human cells and computer modeling may be a useful adjunct to animal studies but will require that such methods are more readily accessible to researchers and are not a replacement for animal experimentation.

Pros and cons of animal experimentation

Arguments against animal experimentation.

A fundamental question surrounding this debate is to ask whether it is appropriate to use animals for medical research. Is our acceptance that animals have a morally lower value or standard of life just a case of speciesism [ 35 ]? Nowadays, most people agree that animals have a moral status and that needlessly hurting or abusing pets or other animals is unacceptable. This represents something of a change from the historical point of view where animals did not have any moral status and the treatment of animals was mostly subservient to maintaining the health and dignity of humans [ 36 ].

Animal rights advocates strongly argue that the moral status of non-human animals is similar to that of humans, and that animals are entitled to equality of treatment. In this view, animals should be treated with the same level of respect as humans, and no one should have the right to force them into any service or to kill them or use them for their own goals. One aspect of this argument claims that moral status depends upon the capacity to suffer or enjoy life [ 37 ].

In terms of suffering and the capacity of enjoying life, many animals are not very different from human beings, as they can feel pain and experience pleasure [ 38 ]. Hence, they should be given the same moral status as humans and deserve equivalent treatment. Supporters of this argument point out that according animals a lower moral status than humans is a type of prejudice known as “speciesism” [ 38 ]. Among humans, it is widely accepted that being a part of a specific race or of a specific gender does not provide the right to ascribe a lower moral status to the outsiders. Many advocates of animal rights deploy the same argument, that being human does not give us sufficient grounds declare animals as being morally less significant [ 36 ].

ARGUMENTS IN FAVOR OF ANIMAL EXPERIMENTATION

Those who support animal experimentation have frequently made the argument that animals cannot be elevated to be seen as morally equal to humans [ 39 ]. Their main argument is that the use of the terms “moral status” or “morality” is debatable. They emphasize that we must not make the error of defining a quality or capacity associated with an animal by using the same adjectives used for humans [ 39 ]. Since, for the most part, animals do not possess humans’ cognitive capabilities and lack full autonomy (animals do not appear to rationally pursue specific goals in life), it is argued that therefore, they cannot be included in the moral community [ 39 ]. It follows from this line of argument that, if animals do not possess the same rights as human beings, their use in research experimentation can be considered appropriate [ 40 ]. The European and the American legislation support this kind of approach as much as their welfare is respected.

Another aspect of this argument is that the benefits to human beings of animal experimentation compensate for the harm caused to animals by these experiments.

In other words, animal harm is morally insignificant compared to the potential benefits to humans. Essentially, supporters of animal experimentation claim that human beings have a higher moral status than animals and that animals lack certain fundamental rights accorded to humans. The potential violations of animal rights during animal research are, in this way, justified by the greater benefits to mankind [ 40 , 41 ]. A way to evaluate when the experiments are morally justified was published in 1986 by Bateson, which developed the Bateson’s Cube [ 42 ]. The Cube has three axes: suffering, certainty of benefit and quality of research. If the research is high-quality, beneficial, and not inflicting suffering, it will be acceptable. At the contrary, painful, low-quality research with lower likelihood of success will not be acceptable [ 42 , 43 ].

Impact of experimentations on animals

Ability to feel pain and distress.

Like humans, animal have certain physical as well as psychological characteristics that make their use for experimentation controversial [ 44 ].

In the last few decades, many studies have increased knowledge of animal awareness and sentience: they indicate that animals have greater potential to experience damage than previously appreciated and that current rights and protections need to be reconsidered [ 45 ]. In recent times, scientists as well as ethicists have broadly acknowledged that animals can also experience distress and pain [ 46 ]. Potential sources of such harm arising from their use in research include disease, basic physiological needs deprivation and invasive procedures [ 46 ]. Moreover, social deprivation and lack of the ability to carry out their natural behaviors are other causes of animal harm [ 46 ]. Several studies have shown that, even in response to very gentle handling and management, animals can show marked alterations in their physiological and hormonal stress markers [ 47 ].

In spite of the fact that suffering and pain are personalized experiences, several multi-disciplinary studies have provided clear evidence of animals experiencing pain and distress. In particular, some animal species have the ability to express pain similarly to human due to common psychological, neuroanatomical and genetic characteristics [ 48 ]. Similarly, animals share a resemblance to humans in their developmental, genetic and environmental risk factors for psychopathology. For instance, in many species, it has been shown that fear operates within a less organized subcortical neural circuit than pain [ 49 , 50 ]. Various types of depression and anxiety disorders like posttraumatic stress disorder have also been reported in mammals [ 51 ].

PSYCHOLOGICAL CAPABILITIES OF ANIMALS

Some researchers have suggested that besides their ability to experience physical and psychological pain and distress, some animals also exhibit empathy, self-awareness and language-like capabilities. They also demonstrate tools-linked cognizance, pleasure-seeking and advanced problem-solving skills [ 52 ]. Moreover, mammals and birds exhibit playful behavior, an indicator of the capacity to experience pleasure. Other taxa such as reptiles, cephalopods and fishes have also been observed to display playful behavior, therefore the current legislation prescribes the use of environmental enrichers [ 53 ]. The presence of self-awareness ability, as assessed by mirror self-recognition, has been reported in magpies, chimpanzees and other apes, and certain cetaceans [ 54 ]. Recently, another study has revealed that crows have the ability to create and use tools that involve episodic-like memory formation and its retrieval. From these findings, it may be suggested that crows as well as related species show evidence of flexible learning strategies, causal reasoning, prospection and imagination that are similar to behavior observed in great apes [ 55 ]. In the context of resolving the ethical dilemmas about animal experimentation, these observations serve to highlight the challenges involved [ 56 , 57 ].

Ethics, principles and legislation in animal experimentation

Ethics in animal experimentation.

Legislation around animal research is based on the idea of the moral acceptability of the proposed experiments under specific conditions [ 58 ]. The significance of research ethics that ensures proper treatment of experimental animals [ 58 ]. To avoid undue suffering of animals, it is important to follow ethical considerations during animal studies [ 1 ]. It is important to provide best human care to these animals from the ethical and scientific point of view [ 1 ]. Poor animal care can lead to experimental outcomes [ 1 ]. Thus, if experimental animals mistreated, the scientific knowledge and conclusions obtained from experiments may be compromised and may be difficult to replicate, a hallmark of scientific research [ 1 ]. At present, most ethical guidelines work on the assumption that animal experimentation is justified because of the significant potential benefits to human beings. These guidelines are often permissive of animal experimentation regardless of the damage to the animal as long as human benefits are achieved [ 59 ].

PRINCIPLE OF THE 4 RS

Although animal experimentation has resulted in many discoveries and helped in the understanding numerous aspects of biological science, its use in various sectors is strictly controlled. In practice, the proposed set of animal experiments is usually considered by a multidisciplinary Ethics Committee before work can commence [ 60 ]. This committee will review the research protocol and make a judgment as to its sustainability. National and international laws govern the utilization of animal experimentation during research and these laws are mostly based on the universal doctrine presented by Russell and Burch (1959) known as principle of the 3 Rs. The 3Rs referred to are Reduction, Refinement and Replacement, and are applied to protocols surrounding the use of animals in research. Some researchers have proposed another “R”, of responsibility for the experimental animal as well as for the social and scientific status of the animal experiments [ 61 ]. Thus, animal ethics committees commonly review research projects with reference to the 4 Rs principles [ 62 ].

The first “R”, Reduction means that the experimental design is examined to ensure that researchers have reduced the number of experimental animals in a research project to the minimum required for reliable data [ 59 ]. Methods used for this purpose include improved experimental design, extensive literature search to avoid duplication of experiments [ 35 ], use of advanced imaging techniques, sharing resources and data, and appropriate statistical data analysis that reduce the number of animals needed for statistically significant results [ 2 , 63 ].

The second “R”, Refinement involves improvements in procedure that minimize the harmful effects of the proposed experiments on the animals involved, such as reducing pain, distress and suffering in a manner that leads to a general improvement in animal welfare. This might include for example improved living conditions for research animals, proper training of people handling animals, application of anesthesia and analgesia when required and the need for euthanasia of the animals at the end of the experiment to curtail their suffering [ 63 ].

The third “R”, Replacement refers to approaches that replace or avoid the use of experimental animals altogether. These approaches involve use of in silico methods/computerized techniques/software and in vitro methods like cell and tissue culture testing, as well as relative replacement methods by use of invertebrates like nematode worms, fruit flies and microorganisms in place of vertebrates and higher animals [ 1 ]. Examples of proper application of these first “3R2 principles are the use of alternative sources of blood, the exploitation of commercially used animals for scientific research, a proper training without use of animals and the use of specimen from previous experiments for further researches [ 64-67 ].

The fourth “R”, Responsibility refers to concerns around promoting animal welfare by improvements in experimental animals’ social life, development of advanced scientific methods for objectively determining sentience, consciousness, experience of pain and intelligence in the animal kingdom, as well as effective involvement in the professionalization of the public discussion on animal ethics [ 68 ].

OTHER ASPECTS OF ANIMAL RESEARCH ETHICS

Other research ethics considerations include having a clear rationale and reasoning for the use of animals in a research project. Researchers must have reasonable expectation of generating useful data from the proposed experiment. Moreover, the research study should be designed in such a way that it should involve the lowest possible sample size of experimental animals while producing statistically significant results [ 35 ].

All individual researchers that handle experimental animals should be properly trained for handling the particular species involved in the research study. The animal’s pain, suffering and discomfort should be minimized [ 69 ]. Animals should be given proper anesthesia when required and surgical procedures should not be repeated on same animal whenever possible [ 69 ]. The procedure of humane handling and care of experimental animals should be explicitly detailed in the research study protocol. Moreover, whenever required, aseptic techniques should be properly followed [ 70 ]. During the research, anesthetization and surgical procedures on experimental animals should only be performed by professionally skilled individuals [ 69 ].

The Animal Research: Reporting of In Vivo Experiments (ARRIVE) guidelines that are issued by the National Center for the Replacement, Refinement, and Reduction of Animals in Research (NC3Rs) are designed to improve the documentation surrounding research involving experimental animals [ 70 ]. The checklist provided includes the information required in the various sections of the manuscript i.e. study design, ethical statements, experimental procedures, experimental animals and their housing and husbandry, and more [ 70 ].

It is critical to follow the highest ethical standards while performing animal experiments. Indeed, most of the journals refuse to publish any research data that lack proper ethical considerations [ 35 ].

INVESTIGATORS’ ETHICS

Since animals have sensitivity level similar to the human beings in terms of pain, anguish, survival instinct and memory, it is the responsibility of the investigator to closely monitor the animals that are used and identify any sign of distress [ 71 ]. No justification can rationalize the absence of anesthesia or analgesia in animals that undergo invasive surgery during the research [ 72 ]. Investigators are also responsible for giving high-quality care to the experimental animals, including the supply of a nutritious diet, easy water access, prevention of and relief from any pain, disease and injury, and appropriate housing facilities for the animal species [ 73 ]. A research experiment is not permitted if the damage caused to the animal exceeds the value of knowledge gained by that experiment. No scientific advancement based on the destruction and sufferings of another living being could be justified. Besides ensuring the welfare of animals involved, investigators must also follow the applicable legislation [ 74 , 75 ].

To promote the comfort of experimental animals in England, an animal protection society named: ‘The Society for the Preservation of Cruelty to Animals’ (now the Royal Society for the Prevention of Cruelty to Animals) was established (1824) that aims to prevent cruelty to animal [ 76 ].

ANIMAL WELFARE LAWS

Legislation for animal protection during research has long been established. In 1876 the British Parliament sanctioned the ‘Cruelty to Animals Act’ for animal protection. Russell and Burch (1959) presented the ‘3 Rs’ principles: Replacement, Reduction and Refinement, for use of animals during research [ 61 ]. Almost seven years later, the U.S.A also adopted regulations for the protection of experimental animals by enacting the Laboratory Animal Welfare Act of 1966 [ 60 ]. In Brazil, the Arouca Law (Law No. 11,794/08) regulates the animal use in scientific research experiments [ 76 ].

These laws define the breeding conditions, and regulate the use of animals for scientific research and teaching purposes. Such legal provisions control the use of anesthesia, analgesia or sedation in experiments that could cause distress or pain to experimental animals [ 59 , 76 ]. These laws also stress the need for euthanasia when an experiment is finished, or even during the experiment if there is any intense suffering for the experimental animal [ 76 ].

Several national and international organizations have been established to develop alternative techniques so that animal experimentation can be avoided, such as the UK-based National Centre for the Replacement, Refinement and Reduction of Animals in Research (NC3Rs) ( www.caat.jhsph.edu ), the European Centre for the Validation of Alternative Methods (ECVAM) [ 77 ], the Universities Federation for Animal Welfare (UFAW) ( www.ufaw.org.uk ), The Interagency Coordinating Committee on the Validation of Alternative Methods (ICCVAM) [ 78 ], and The Center for Alternatives to Animal Testing (CAAT) ( www.caat.jhsph.edu ). The Brazilian ‘Arouca Law’ also constitutes a milestone, as it has created the ‘National Council for the Control of Animal Experimentation’ (CONCEA) that deals with the legal and ethical issues related to the use of experimental animals during scientific research [ 76 ].

Although national as well as international laws and guidelines have provided basic protections for experimental animals, the current regulations have some significant discrepancies. In the U.S., the Animal Welfare Act excludes rats, mice and purpose-bred birds, even though these species comprise almost 90% of the animals that are used for research purpose [ 79 ]. On the other hand, certain cats and dogs are getting special attention along with extra protection. While the U.S. Animal Welfare Act ignores birds, mice and rats, the U.S. guidelines that control research performed using federal funding ensure protections for all vertebrates [ 79 , 80 ].

Living conditions of animals

Choice of the animal model.

Based on all the above laws and regulations and in line with the deliberations of ethical committees, every researcher must follow certain rules when dealing with animal models.

Before starting any experimental work, thorough research should be carried out during the study design phase so that the unnecessary use of experimental animals is avoided. Nevertheless, certain research studies may have compelling reasons for the use of animal models, such as the investigation of human diseases and toxicity tests. Moreover, animals are also widely used in the training of health professionals as well as in training doctors in surgical skills [ 1 , 81 ].

Researcher should be well aware of the specific traits of the animal species they intend to use in the experiment, such as its developmental stages, physiology, nutritional needs, reproductive characteristics and specific behaviors. Animal models should be selected on the basis of the study design and the biological relevance of the animal [ 1 ].

Typically, in early research, non-mammalian models are used to get rapid insights into research problems such as the identification of gene function or the recognition of novel therapeutic options. Thus, in biomedical and biological research, among the most commonly used model organisms are the Zebrafish, the fruit fly Drosophila melanogaster and the nematode Caenorhabditis elegans . The main advantage of these non-mammalian animal models is their prolific reproducibility along with their much shorter generation time. They can be easily grown in any laboratory setting, are less expensive than the murine animal models and are somewhat more powerful than the tissue and cell culture approaches [ 82 ].

Caenorhabditis elegans is a small-sized nematode with a short life cycle and that exists in large populations and is relatively inexpensive to cultivate. Scientists have gathered extensive knowledge of the genomics and genetics of Caenorhabditis elegans ; but Caenorhabditis elegans models, while very useful in some respects, are unable to represent all signaling pathways found in humans. Furthermore, due to its short life cycle, scientists are unable to investigate long term effects of test compounds or to analyze primary versus secondary effects [ 6 ].

Similarly, the fruit fly Drosophila melanogaster has played a key role in numerous biomedical discoveries. It is small in size, has a short life cycle and large population size, is relatively inexpensive to breed, and extensive genomics and genetics information is available [ 6 ]. However, its respiratory, cardiovascular and nervous systems differ considerably from human beings. In addition, its immune system is less developed when compared to vertebrates, which is why effectiveness of a drug in Drosophila melanogaster may not be easily extrapolated to humans [ 83 ].

The Zebrafish ( Danio rerio ) is a small freshwater teleost, with transparent embryos, providing easy access for the observation of organogenesis and its manipulation. Therefore, Zebrafish embryos are considered good animal models for different human diseases like tuberculosis and fetal alcohol syndrome and are useful as neurodevelopmental research models. However, Zebrafish has very few mutant strains available, and its genome has numerous duplicate genes making it impossible to create knockout strains, since disrupting one copy of the gene will not disrupt the second copy of that gene. This feature limits the use of Zebrafish as animal models to study human diseases. Additionally they are rather expensive, have long life cycle, and genomics and genetics studies are still in progress [ 82 , 84 ].

Thus, experimentation on these three animals might not be equivalent to experimentation on mammals. Mammalian animal model are most similar to human beings, so targeted gene replacement is possible. Traditionally, mammals like monkey and mice have been the preferred animal models for biomedical research because of their evolutionary closeness to humans. Rodents, particularly mice and rats, are the most frequently used animal models for scientific research. Rats are the most suitable animal model for the study of obesity, shock, peritonitis, sepsis, cancer, intestinal operations, spleen, gastric ulcers, mononuclear phagocytic system, organ transplantations and wound healing. Mice are more suitable for studying burns, megacolon, shock, cancer, obesity, and sepsis as mentioned previously [ 85 ].

Similarly, pigs are mostly used for stomach, liver and transplantation studies, while rabbits are suitable for the study of immunology, inflammation, vascular biology, shock, colitis and transplantations. Thus, the choice of experimental animal mainly depends upon the field of scientific research under consideration [ 1 ].

HOUSING AND ENVIRONMENTAL ENRICHMENT

Researchers should be aware of the environment and conditions in which laboratory animals are kept during research, and they also need to be familiar with the metabolism of the animals kept in vivarium, since their metabolism can easily be altered by different factors such as pain, stress, confinement, lack of sunlight, etc. Housing conditions alter animal behavior, and this can in turn affect experimental results. By contrast, handling procedures that feature environmental enrichment and enhancement help to decrease stress and positively affect the welfare of the animals and the reliability of research data [ 74 , 75 ].

In animals, distress- and agony-causing factors should be controlled or eliminated to overcome any interference with data collection as well as with interpretation of the results, since impaired animal welfare leads to more animal usage during experiment, decreased reliability and increased discrepancies in results along with the unnecessary consumption of animal lives [ 86 ].

To reduce the variation or discrepancies in experimental data caused by various environmental factors, experimental animals must be kept in an appropriate and safe place. In addition, it is necessary to keep all variables like humidity, airflow and temperature at levels suitable for those species, as any abrupt variation in these factors could cause stress, reduced resistance and increased susceptibility to infections [ 74 ].

The space allotted to experimental animals should permit them free movement, proper sleep and where feasible allow for interaction with other animals of the same species. Mice and rats are quite sociable animals and must, therefore, be housed in groups for the expression of their normal behavior. Usually, laboratory cages are not appropriate for the behavioral needs of the animals. Therefore, environmental enrichment is an important feature for the expression of their natural behavior that will subsequently affect their defense mechanisms and physiology [ 87 ].

The features of environmental enrichment must satisfy the animals’ sense of curiosity, offer them fun activities, and also permit them to fulfill their behavioral and physiological needs. These needs include exploring, hiding, building nests and gnawing. For this purpose, different things can be used in their environment, such as PVC tubes, cardboard, igloos, paper towel, cotton, disposable masks and paper strips [ 87 ].

The environment used for housing of animals must be continuously controlled by appropriate disinfection, hygiene protocols, sterilization and sanitation processes. These steps lead to a reduction in the occurrence of various infectious agents that often found in vivarium, such as Sendai virus, cestoda and Mycoplasma pulmonis [ 88 ].

Euthanasia is a term derived from Greek, and it means a death without any suffering. According to the Brazilian Arouca Law (Article 14, Chapter IV, Paragraphs 1 and 2), an animal should undergo euthanasia, in strict compliance with the requirements of each species, when the experiment ends or during any phase of the experiment, wherever this procedure is recommended and/or whenever serious suffering occurs. If the animal does not undergo euthanasia after the intervention it may leave the vivarium and be assigned to suitable people or to the animal protection bodies, duly legalized [ 1 ].

Euthanasia procedures must result in instant loss of consciousness which leads to respiratory or cardiac arrest as well as to complete brain function impairment. Another important aspect of this procedure is calm handling of the animal while taking it out of its enclosure, to reduce its distress, suffering, anxiety and fear. In every research project, the study design should include the details of the appropriate endpoints of these experimental animals, and also the methods that will be adopted. It is important to determine the appropriate method of euthanasia for the animal being used. Another important point is that, after completing the euthanasia procedure, the animal’s death should be absolutely confirmed before discarding their bodies [ 87 , 89 ].

Relevance of animal experimentations and possible alternatives

Relevance of animal experiments and their adverse effects on human health.

One important concern is whether human diseases, when inflicted on experimental animals, adequately mimic the progressions of the disease and the treatment responses observed in humans. Several research articles have made comparisons between human and animal data, and indicated that the results of animals’ research could not always be reliably replicated in clinical research among humans. The latest systematic reviews about the treatment of different clinical conditions including neurology, vascular diseases and others, have established that the results of animal studies cannot properly predict human outcomes [ 59 , 90 ].

At present, the reliability of animal experiments for extrapolation to human health is questionable. Harmful effects may occur in humans because of misleading results from research conducted on animals. For instance, during the late fifties, a sedative drug, thalidomide, was prescribed for pregnant women, but some of the women using that drug gave birth to babies lacking limbs or with foreshortened limbs, a condition called phocomelia. When thalidomide had been tested on almost all animal models such as rats, mice, rabbits, dogs, cats, hamsters, armadillos, ferrets, swine, guinea pig, etc., this teratogenic effect was observed only occasionally [ 91 ]. Similarly, in 2006, the compound TGN 1412 was designed as an immunomodulatory drug, but when it was injected into six human volunteer, serious adverse reactions were observed resulting from a deadly cytokine storm that in turn led to disastrous systemic organ failure. TGN 1412 had been tested successfully in rats, mice, rabbits, and non-human primates [ 92 ]. Moreover, Bailey (2008) reported 90 HIV vaccines that had successful trial results in animals but which failed in human beings [ 93 ]. Moreover, in Parkinson disease, many therapeutic options that have shown promising results in rats and non-human primate models have proved harmful in humans. Hence, to analyze the relevance of animal research to human health, the efficacy of animal experimentation should be examined systematically [ 94 , 95 ]. At the same time, the development of hyperoxaluria and renal failure (up to dialysis) after ileal-jejunal bypass was unexpected because this procedure was not preliminarily evaluated on an animal model [ 96 ].

Several factors play a role in the extrapolation of animal-derived data to humans, such as environmental conditions and physiological parameters related to stress, age of the experimental animals, etc. These factors could switch on or off genes in the animal models that are specific to species and/or strains. All these observations challenge the reliability and suitability of animal experimentation as well as its objectives with respect to human health [ 76 , 92 ].

ALTERNATIVE TO ANIMAL EXPERIMENTATION/DEVELOPMENT OF NEW PRODUCTS AND TECHNIQUES TO AVOID ANIMAL SACRIFICE IN RESEARCH

Certainly, in vivo animal experimentation has significantly contributed to the development of biological and biomedical research. However it has the limitations of strict ethical issues and high production cost. Some scientists consider animal testing an ineffective and immoral practice and therefore prefer alternative techniques to be used instead of animal experimentation. These alternative methods involve in vitro experiments and ex vivo models like cell and tissue cultures, use of plants and vegetables, non-invasive human clinical studies, use of corpses for studies, use of microorganisms or other simpler organism like shrimps and water flea larvae, physicochemical techniques, educational software, computer simulations, mathematical models and nanotechnology [ 97 ]. These methods and techniques are cost-effective and could efficiently replace animal models. They could therefore, contribute to animal welfare and to the development of new therapies that can identify the therapeutics and related complications at an early stage [ 1 ].

The National Research Council (UK) suggested a shift from the animal models toward computational models, as well as high-content and high-throughput in vitro methods. Their reports highlighted that these alternative methods could produce predictive data more affordably, accurately and quickly than the traditional in vivo or experimental animal methods [ 98 ].

Increasingly, scientists and the review boards have to assess whether addressing a research question using the applied techniques of advanced genetics, molecular, computational and cell biology, and biochemistry could be used to replace animal experiments [ 59 ]. It must be remembered that each alternative method must be first validated and then registered in dedicated databases.

An additional relevant concern is how precisely animal data can mirror relevant epigenetic changes and human genetic variability. Langley and his colleagues have highlighted some of the examples of existing and some emerging non-animal based research methods in the advanced fields of neurology, orthodontics, infectious diseases, immunology, endocrine, pulmonology, obstetrics, metabolism and cardiology [ 99 ].

IN SILICO SIMULATIONS AND INFORMATICS

Several computer models have been built to study cardiovascular risk and atherosclerotic plaque build-up, to model human metabolism, to evaluate drug toxicity and to address other questions that were previously approached by testing in animals [ 100 ].

Computer simulations can potentially decrease the number of experiments required for a research project, however simulations cannot completely replace laboratory experiments. Unfortunately, not all the principles regulating biological systems are known, and computer simulation provide only an estimation of possible effects due to the limitations of computer models in comparison with complex human tissues. However, simulation and bio-informatics are now considered essential in all fields of science for their efficiency in using the existing knowledge for further experimental designs [ 76 ].

At present, biological macromolecules are regularly simulated at various levels of detail, to predict their response and behavior under certain physical conditions, chemical exposures and stimulations. Computational and bioinformatic simulations have significantly reduced the number of animals sacrificed during drug discovery by short listing potential candidate molecules for a drug. Likewise, computer simulations have decreased the number of animal experiments required in other areas of biological science by efficiently using the existing knowledge. Moreover, the development of high definition 3D computer models for anatomy with enhanced level of detail, it may make it possible to reduce or eliminate the need for animal dissection during teaching [ 101 , 102 ].

3D CELL-CULTURE MODELS AND ORGANS-ON-CHIPS

In the current scenario of rapid advancement in the life sciences, certain tissue models can be built using 3D cell culture technology. Indeed, there are some organs on micro-scale chip models used for mimicking the human body environment. 3D models of multiple organ systems such as heart, liver, skin, muscle, testis, brain, gut, bone marrow, lungs and kidney, in addition to individual organs, have been created in microfluidic channels, re-creating the physiological chemical and physical microenvironments of the body [ 103 ]. These emerging techniques, such as the biomedical/biological microelectromechanical system (Bio-MEMS) or lab-on-a-chip (LOC) and micro total analysis systems (lTAS) will, in the future, be a useful substitute for animal experimentation in commercial laboratories in the biotechnology, environmental safety, chemistry and pharmaceutical industries. For 3D cell culture modeling, cells are grown in 3D spheroids or aggregates with the help of a scaffold or matrix, or sometimes using a scaffold-free method. The 3D cell culture modeling conditions can be altered to add proteins and other factors that are found in a tumor microenvironment, for example, or in particular tissues. These matrices contain extracellular matrix components such as proteins, glycoconjugates and glycosaminoglycans that allow for cell communication, cell to cell contact and the activation of signaling pathways in such a way that the morphological and functional differentiation of these cells can accurately mimic their environment in vivo . This methodology, in time, will bridge the gap between in vivo and in vitro drug screening, decreasing the utilization of animal models during research [ 104 ].

ALTERNATIVES TO MICROBIAL CULTURE MEDIA AND SERUM-FREE ANIMAL CELL CULTURES

There are moves to reduce the use of animal derived products in many areas of biotechnology. Microbial culture media peptones are mostly made by the proteolysis of farmed animal meat. However, nowadays, various suppliers provide peptones extracted from yeast and plants. Although the costs of these plant-extracted peptones are the same as those of animal peptones, plant peptones are more environmentally favorable since less plant material and water are required for them to grow, compared with the food grain and fodder needed for cattle that are slaughtered for animal peptone production [ 105 ].

Human cell culture is often carried out in a medium that contains fetal calf serum, the production of which involves animal (cow) sacrifice or suffering. In fact, living pregnant cows are used and their fetuses removed to harvest the serum from the fetal blood. Fetal calf serum is used because it is a natural medium rich in all the required nutrients and significantly increases the chances of successful cell growth in culture. Scientists are striving to identify the factors and nutrients required for the growth of various types of cells, with a view to eliminating the use of calf serum. At present, most cell lines could be cultured in a chemically-synthesized medium without using animal products. Furthermore, data from chemically-synthesized media experiments may have better reproducibility than those using animal serum media, since the composition of animal serum does change from batch to batch on the basis of animals’ gender, age, health and genetic background [ 76 ].

ALTERNATIVES TO ANIMAL-DERIVED ANTIBODIES

Animal friendly affinity reagents may act as an alternative to antibodies produced, thereby removing the need for animal immunization. Typically, these antibodies are obtained in vitro by yeast, phage or ribosome display. In a recent review, a comparative analysis between animal friendly affinity reagents and animal derived-antibodies showed that the affinity reagents have superior quality, are relatively less time consuming, have more reproducibility and are more reliable and are cost-effective [ 106 , 107 ].

Conclusions

Animal experimentation led to great advancement in biological and biomedical sciences and contributed to the discovery of many drugs and treatment options. However, such experimentation may cause harm, pain and distress to the animals involved. Therefore, to perform animal experimentations, certain ethical rules and laws must be strictly followed and there should be proper justification for using animals in research projects. Furthermore, during animal experimentation the 4 Rs principles of reduction, refinement, replacement and responsibility must be followed by the researchers. Moreover, before beginning a research project, experiments should be thoroughly planned and well-designed, and should avoid unnecessary use of animals. The reliability and reproducibility of animal experiments should also be considered. Whenever possible, alternative methods to animal experimentation should be adopted, such as in vitro experimentation, cadaveric studies, and computer simulations.

While much progress has been made on reducing animal experimentation there is a need for greater awareness of alternatives to animal experiments among scientists and easier access to advanced modeling technologies. Greater research is needed to define a roadmap that will lead to the elimination of all unnecessary animal experimentation and provide a framework for adoption of reliable alternative methodologies in biomedical research.

Animal Testing Essay

Posted by David S. Wills | Oct 21, 2022 | Model Essays | 0

There is a wide range of topics used in the IELTS writing test and many of them overlap. Today, we are going to look at a question that falls between the topics of animals and ethics and science. It will require you to write an animal testing essay .

In this article, I will analyse the question for you, give you some pointers on useful language, and then show you my own sample band 9 answer.

The Task: Animal Testing

Here is a question that appeared in the IELTS exam several years ago:

Some people claim that it is acceptable to use animals in medical research for the benefit of human beings, while other people argue that it is wrong. Discuss both views and give your opinion.

(Note that questions can be re-used or re-written, so it is possible that you might see this recycled in the future.)

This is a “discuss both views” question , so your task is ultimately to do three things:

• Explain why some people think animal testing is acceptable
• Explain why some people think animal testing is unacceptable
• Give your opinion

Even if you feel really strongly that it is wrong, for example, you still need to explain the opposing view. You don’t need to give a balanced answer , but you do need to acknowledge both sides of the debate. This is important for Task Response.

Planning your Answer

I almost always write a four-paragraph essay for my sample band 9 answers but today I’m going to write five. It could easily have been four paragraphs but I wanted to separate my anti-animal testing arguments into two separate paragraphs for better organisation. (You can read about 4- vs 5-paragraph essay structures here .)

My essay is going to look like this:

When it comes to a task 2 introduction , please make sure that you have a clear outline sentence and also that your opinion (if one is required) is stated clearly.

Body paragraph 1 will act as a sort of concession paragraph , so it will be imperative that I make it clear that this is not my opinion but rather what some other people think. If I fail to do this, then the reader might be confused.

The ideas in body paragraphs 2 and 3 will be separated but could also have been condensed into two paragraphs. However, I felt that for this topic it was a little more effective to split them. It also made my argument slightly more persuasive.

For the conclusion , I will be careful not to repeat myself too much and instead just summarise and reaffirm my stance.

Language for an Animal Testing Essay

The topic of animal testing is obviously controversial and so people will have different ideas. What you say will be largely based upon your own opinions. However, keep in mind that it covers those three topics I mentioned:

You don’t really need to know a lot about each, but it definitely would have some benefit if you knew a little about these areas and had some good vocabulary to use. I wrote about the IELTS topic of animals here , and there is plenty of good vocabulary that you can borrow. You can also search “animals” in the search bar at the top of the page.

I also recommend that you read and listen on issues that are related to IELTS topics like this. I particularly recommend the SYSK podcast episode on animal testing, which I think it is informative and accessible. You may learn some good language and get some inspiration for what you could write in your own animal testing essay. Other sources include this argument against animal testing by PETA and this one in favour of it by Stanford.

Language for Contentious Issues

In my essay, I will use the following phrases, which could be modified and applied to other contentious issues. I will put the specific language in brackets, so that you could swap it out when discussing other topics:

• [animal testing] has been fiercely debated due to the ethical problems inherent in this area of [science]
• The people who believe that [animal testing] is necessary tend to say…
• this is wrong for several reasons
• [animal testing] is not as helpful in [developing medicines] as people think
• There are many other reasons why [experimenting with animals] is wrong
• it is grossly unethical to [subject these creatures to painful and demeaning experiences]
• people may argue that there are benefits that come from [experimenting on animals], but in fact there is no good reason to continue doing this

You can try using and modifying these phrases in your own practice essays. If you want an expert to correct them for you, try my IELTS writing correction service .

Language about Animal Testing

The following phrases will also appear in my essay and can be used for talking about animal testing:

• this area of science
• animal testing should be banned
• testing medicines before using them on human beings
• figure out the cures to many serious illnesses
• Medicines that work on animals do not always work on humans
• if scientists give a mouse diabetes and then try various drugs to cure the problem
• subject these creatures to painful and demeaning experiences
• They are sentient beings
• subjected to cruel and often unnecessary experiments
• harmful both to humans and animals

It is also important to avoid repetition and that means finding ways to say “animal testing” without repeating the say words over and over. You could say:

• testing on animals
• experimenting on animals
• subjecting animals to medical experiments
• using animals in experiments

Again, it would be helpful to read articles and listen to podcasts on this topic in order to improve your vocabulary.

Sample Band 9 Answer

Over the past few decades, animal testing has been fiercely debated due to the ethical problems inherent in this area of science. This essay will look at both sides of the debate, before concluding that animal testing should be banned.

The people who believe that animal testing is necessary tend to say that there are serious benefits to humanity, such as testing medicines before using them on human beings. They believe that this will help to figure out the cures to many serious illnesses, which will make the world a better place for humans. However, this is wrong for several reasons.

Firstly, animal testing is not as helpful in developing medicines as people think. Medicines that work on animals do not always work on humans, and vice versa. As such, these trials are not just unnecessary but also profoundly unhelpful. For example, if scientists give a mouse diabetes and then try various drugs to cure the problem, they may find that there are twelve drugs that do not work on the mouse. However, maybe one of those drugs would have worked on a human. As such, animal testing would have caused more problems than it solved.

There are many other reasons why experimenting with animals is wrong. Perhaps most importantly, it is grossly unethical to subject these creatures to painful and demeaning experiences for the benefit of humanity. Animals do not exist for the benefit of people. They are sentient beings that deserve better than to be caged and subjected to cruel and often unnecessary experiments.

In conclusion, people may argue that there are benefits that come from experimenting on animals, but in fact there is no good reason to continue doing this. At best, these experiments are useless and at worst they are unethical and harmful both to humans and animals.

Final Notes

You can see that I have carefully crafted an argument that is strong. You may not agree with it, but it is hard to deny my points, which makes it effective in terms of Task Response. The structure is also solid and the ideas were well connected, making it very good in terms of Coherence and Cohesion . Note the inclusion of realistic and interesting ideas as well as concrete examples. My explanation of testing on mice was particularly effective here. It is better than giving some vague or unexplained idea.

Animal Testing Argumentative Essay: Guidelines

How to Write a Great Animal Testing Argumentative Essay?

Animal testing sample.

According to the statistical data, testing in the US is conducted on 26 million animals. Those animals are used for research in the field of commercial products and various scientific advancements. Besides, animals are used to test the latest medical treatment, check on the toxicity of drugs, and verify the level of safety that the products aimed at people will have. Animal testing is also in demand in the commercial industry and the area of health care. Since it is an issue of intense arguments whether it is ethically correct to use the animals in experiments, an animal testing argumentative essay is among the most popular topics at schools, colleges, and universities.

The idea to use animals in experiments is not new. Actually, it is a practice that dates back to 500 BC; and even at that time, there were those who supported this idea and those who were against it. The latter claim that it is cruel and inhumane to test the products using animals, and they call for the development of the new alternative techniques which will eliminate the need for animal testing.

Such organizations as PETA campaign in order to increase the range of relevant research and make the process of developing alternative testing methods faster and more efficient. It is reasonable that an animal testing essay of a student who supports this point of view will state the requirement to alleviate testing on animals. It will also contain an argument that animal testing does not ensure absolutely valid results as tests conducted on animals are different from those done to humans; that is why the question is whether animal testing has any practical sense at all.

Good Argumentative Essay Topics

On the other hand, an argumentative essay on animal testing can be written from the point of view of the advantages of the use of animals in medicine. It is wrong to hurt living beings, but it is necessary to test the safety of new products before using them for the benefit of people. Typically, rats are the first animals used for research. In case the tests prove to be effective, monkeys are the next subjects for a series of tests. Only if these experiments are successful, the product can be given to people.

An animal testing argumentative essay always mentions the benefit of reducing the number of errors and fatal mistakes owing to a round of tests on animals. It also mentions that the number of saved people’s lives is enormous owing to the sacrificed lives of animals. Actually, there is hardly any effective alternative to animal testing. Furthermore, it is subject to following strict regulations to ensure the prevention of all kinds of animal mistreatment.

In general, the debates over the use of animals in testing for medical research testing have been historically known for centuries. After the animal testing essay introduction, it is typical to present the claims of the proponents. They imply that there is no intentional harm in animal testing; moreover, the animals are well kept, fed, and treated nicely. Besides, they state that the absence of effective alternatives makes it impossible to eliminate this practice. They also emphasize the benefit of saving lives owing to animal testing. Nevertheless, certain environmental organizations aimed at the protection of animals call for no more animals in research and testing because of the cruel and inhumane practices.

Writing an animal testing argumentative essay outline , one should take into consideration that animal testing is a matter of various discussions. Thus, it is important to choose a certain position and focus the whole assignment on this point of view. A common task for the students is to work on an argumentative paper; thus, it is essential to determine and specify a definite position and then develop a thesis statement with the supporting arguments appropriately. For instance, if you make up your mind to look at the animal testing from the angle of supporting position, it is recommended to use the following arguments or similar ones.

Writing Prompts for Animal Testing Essays

Advantages to Write About in Animal Testing Essay

It is impossible to eliminate animal testing as it saves people’s lives.

According to medical researchers, the contribution of testing on animals in the advancement of health care and medicine cannot be overestimated. It is owing to the experiments conducted on animals, people can be treated for breast cancer, tuberculosis, diabetics, malaria, brain injury, and other diseases. Physicians also emphasize the role of chimpanzees in experiments aimed at looking for treatment for Hepatitis B and Hepatitis C.

There Is No Alternative to Experimenting with Animals Because Its the Safest Testing Method Known

An animal testing essay conclusion always refers to the fact that the structure of animals’ organisms that resembles that of humans makes them the most suitable material for research in product testing in the fields of medicine and cosmetics. Animal and human bodies have identical or similar processes. There is an assumption that testing can be conducted on cell organisms, but it is doubtful that it will work, as those tissues cannot be tested for blindness or blood pressure issues.

Currently, animal testing is used as a model for computer programs that will probably substitute it in the future. The provided data prove to be accurate; however, living organisms cannot be replaced with less complex computer programs that do not ensure stimulation of the brain activity.

The Biological Similarity between Animal Species and People Is the Best

The organs of the mammals are identical to those of people; besides, there is a striking genetic closeness between them. The statistical data prove that the genetic similarity between the people and mammals can be up to 98%. Animals have the same bloodstream and central nervous systems with humans; that is why the susceptibility to diseases of both of them is similar.

Client's Review

" Recently I strongly needed professional help with writing a nursing essay. I decided to order one from the Elite Writing service. The essay was done on time without any problems. I am grateful for the help. "

Ethical Side of Animal Testing

Each essay about animal testing contains an argument about checking of medical treatment for toxicity during the animal testing procedures. It is against all ethical norms to test a new medicine on people and risk their lives. Helsinki Medical Association claims that animal testing should always go before human experiments

Additional Benefits for Animals

As a result of vaccine testing on animals, not only people but animals are saved from terminal diseases. Besides, the development of new medical products contributes to the prevention of species extinction.

Animal Testing Has the Strict Regulations

Various animal testing essay examples demonstrate that there are strict regulations for experimenting with animals nowadays. A topical issue of present-day life is the protection of animal rights, and numerous organizations control the situation. It is important to make sure that there is neither violation of animal rights not the suffering of animals from abuse.

Further Advantages of Animal Testing

The life cycles of animals are shorter than those of people; thus, the experiments on them are more reasonable than those on humans. It is possible to observe all consequences and effects of certain drugs owing to short life cycles in the course of several years or even months.

Animal Testing Implies Humane Treatment

Some students even use the fact of humane treatment of animals in the animal testing essay title. Researchers always take into account the conditions and consequences of experiments and care about animals.

Disadvantages to Write About in Animal Testing Essay

A variety of animal testing essay topics implies considering different opinions of the pros and cons of those experiments. It is important to ensure the presence of alternative ideas to prevent all kinds of bias and ensure having different perspectives on the same issue.

Human societies have always been oriented at innovation and adaptability as desired features. On the other hand, old practices have the tendency of being kept by the researchers and organizations for a number of reasons. In an animal testing argumentative essay, the aspects should be explored in detail.

First of all, let us talk about the benefits.

Ethics in Animal Testing

If the essay is written in support of animal testing, this is one of the easiest points. Animals used for testing lack moral capabilities and conscious mind despite having their DNA equal to the human one in 98 %. A good animal testing essay title always mentions this somehow. Nevertheless, animals suffer and their agony can lead to death in some serious cases.

Try to explore the issues philosophically. Touch upon attributing value to people and animals. Mention the patients with mental illnesses who have no morality or consciousness. Consider the appropriateness of experimenting on such people along with the animals.

An efficient animal testing pros and cons essay should be based on a broad topic and numerous implications for analysis.

Availability of Alternatives

The progress cannot be stopped in the present-day world. It is normal now to get rid of outdated things and introduce innovations. In a perfect why animal testing should be banned essay, try to note that there are and there will be other ways to experiment on new products. For example, it is possible to cultivate human cells and do organ replication in the laboratories to use the obtained organs for testing of biological processes.

Right, all challenges in modern research cannot be addressed via cell testing; besides, the immune system, endocrine system, blood pressure issues and other aspects of the human body cannot be analyzed using cells. On the other hand, testing practices in the laboratories can substitute some animal alternatives, if possible.

Reduction, Refinement, and Replacement

The mentioned three RRRs (reduction, refinement, and replacement) represent a plan developed by numerous countries to ensure the decrease in the testing with the use of animals. A cosmetic animal testing essay should contain this argument for explanations of why it is important to eradicate the common practice.

• What is the reduction ?

It is the minimization of the animal testing practice by research centers, laboratories, and companies, and regulation of the affected living creatures via introducing innovative practices and improving the experimental techniques.

• What is refinement ?

It is changing the lives of tested animals, ensuring good living conditions, the introduction of obligatory anesthesia, and the provision of necessary medical treatment.

• What is the replacement ?

It is a procedure of transition to innovative methods of conducting experiments with the use of computers, cell culture, micro-dosing by volunteers, human tissue tissues, and other methods.

Overrating of the Contribution

An argument that animal testing should be illegal is used by numerous researchers against the current testing practices. The supporters of the theory cite examples to prove the inevitability of animal experiments for the progress of humans. Nevertheless, it is complicated to make a prediction on how the discoveries can be made without animal testing, but the ideas of progress cannot be based on outdated practices.

It cannot be denied that the development of insulin was made owing to the dogs that had pancreases injected. On the other hand, a medical student from Germany, Paul Langerhans, saw the strange pancreatic tissue cells and encouraged Frederick Banting to make a discovery without any animal testing. Thus, there is a question of whether the disadvantages of animal testing outweigh the benefits obtained. The use of dogs sped up the process but kills many innocent animals. Insulin helped many people survive, but it is complicated to determine how the studies will be affected by animal testing results.

Insufficient Reliability

The efficiency of the animal tests on people is 95% because of the 2% genome divergence between animals and people. The European Union banned the use of animals in testing cosmetics for two reasons. Firstly, the eyes of humans are less sensitive than the eyes of rats and some other animals, thus the experiment results are unreliable. Secondly, other alternatives, for example, tissue testing, can be more effective.

Some researchers claim that animal testing should be allowed, but insufficient reliability may result in tragedies. For instance, tension, anxiety, and insomnia were treated with thalidomide medication in West Germany, and in 1957, as many as 5,000 infants died, and many lost sights, hearing or suffered severe deformities. It is not always right to use the products suitable for animals on humans. Another example is Rezulin that was a trigger of liver failure in people but treated rats with diabetes type 2 perfectly.

High Price of Animal Tests

It is common to pay no attention to this fact. It is assumed that more innovative technology will be even more expensive; however, progress always implies durability, and that should be noted. Financial losses are huge even for common dissection classes. Reliable results require numerous life forms, but computer models can use the required data for analysis in a different way.

Leaving out the Rights

The governments adopted a number of regulations in different countries of the world to ensure the protection of animals’ rights; however, it is a common practice to forget about the animals used for testing when it goes about laws.

Thinking about a good title for an essay on animal testing for medical purposes, do not forget to take into consideration this debatable point. How can it happen that the Animal Welfare Act omits fish, mice, and rats? The researchers are allowed to treat those animals in the way they need for their experiments. Try to explore how moral this situation is.

Global Progress

Your essay should emphasize the crucial importance of certain practices and lack of alternatives; however, it is also essential to touch upon the better options, available now o expected in the future. Every year, the development of technologies causes the emergence of new experimenting methods, making science more efficient and more humane. Mention the subjective opinions of the researchers and limitations of the control samples when talking about animal testing. On the other hand, note the advantages of new computer models that avoid bias and manipulation of data. Animals are less close to people than in cell cultures. All in all, it is more ethical to try alternative testing techniques as they not only protect the animals but also increase the efficiency of science.

Animal Testing: Long and Unpretty History Essay

History of animal testing, animal testing is cruel, animal testing and its types, laws and animal testing, animal testing is ineffective, examples of the ineffectiveness of animal testing, alternatives to animal testing.

In general, animal testing is allowed all over the world. Some countries impose certain restrictions on that matter, some – do not introduce any restrictions at all. However, even those countries that have certain laws prohibiting tests on animals do not take into account the fact that animals are living creatures and must not suffer for the sake of an experiment. Moreover, in most facilities and laboratories, animals are kept in cages, thereby having absolutely no freedom. Most of the experiments performed on animals bring them suffering, lead to disability, and even death. This inhumane treatment of animals does not justify any cause (Haugen, 2000). Thus, the main reason why these experiments must be stopped is that, according to the statistics, the majority of them are ineffective and inaccurate.

Animal testing has a long history. Considering the fact that animals are living creatures, medical experiments on them were already conducted at least three thousand years ago. The first records mentioning the experiments on animals date back to the fourth century BCE in Ancient Greece (Murnaghan, 2017). Thus, in ancient times, it was a widely adopted practice to perform dissections of animals in order to understand how to make surgical operations on humans.

Since the 18 th century, with the development of medicine, the frequency of animal testing has significantly increased. Moreover, if a couple of centuries ago, there were only single experiments that were performed by separate scientists, now, it has developed into the large industry that catches animals in the wild and uses them as guinea pigs (Scutti, 2013). Thus, although there are many innovative technologies that can serve as better alternatives to animal testing, people are still reluctant to change the current state of affairs.

Despite animal testing being rather an old practice, ethical considerations on that matter also occurred quite a long time ago (Scutti, 2013). For example, in the 17 th century, a psychologist Edmund O’Meara stated that animal testing was unnecessary, as it often gave inaccurate results. In this respect, he provided an example regarding vivisection that, as he claimed, placed the body of an animal in an unnatural state, in which it endured a lot of pain that was both cruel and gave false results.

The first animal protection law was established in Great Britain in 1822. A significant milestone in the history of animal protection legislation was the introduction of the Cruelty to Animals Act in 1876 in Great Britain. This law was promoted by Charles Darwin who, despite being a biologist and a scientist, was against vivisection. In the 1860s, the movements against animal testing occurred in the USA. As a result, Henry Bergh established the American Society for the Prevention of Cruelty to Animals (ASPCA) in 1866. After that, the American Anti-Vivisection Society (AAVS) was founded in 1883 (Haugen, 2000). Thus, the end of the 19 th century was the time when many articles were written, and campaigns were started calling for terminating the experiments on animals.

However, at the beginning of the 20 th century, the tendency of releasing laws about animal protection changed. Unfortunately, the efforts of antivivisectionists to promote their campaigns to make the US government to ban animal testing failed due to the overall support of such experiments by the public, which was assured by the organizations who performed these experiments that animals were kept in good conditions, bred well, and injected with anaesthetics in those operations that could cause them much pain. Therefore, only in the 1960s, the efforts of antivivisectionists were partially justified, with the release of the Laboratory Animal Welfare Act in 1966 (Haugen, 2000). Nevertheless, that law was more focused on the welfare of animals in laboratories rather than on the prohibition of animal testing.

Nowadays, there are a great number of organizations that advocate for stopping using animals in the experiments. Although the overall effectiveness of their campaigns is quite low, they have managed to achieve some positive results concerning the problem of animal testing (Murnaghan, 2017). Additionally, considering the current tendency of the active development of various technologies that can easily substitute experiments on animals, there is hope that soon the animal testing industry will cease to exist.

The first argument against animal testing is that it is simply cruel. People must understand that animals are the same living creature as them and can feel both psychological and physical pain in the same way as humans. Thus, in the case of experimenting on animals, the ethical and humane aspects of the issue must prevail and give people a stimulus to seek for other ways of studying diseases that can be much better.

First of all, it is necessary to describe the types of animal testing in order to understand the degree of the cruelty of these experiments. In general, animal testing is the process of experimenting on animals where they usually undergo various medical procedures which cause them suffering or even death. These experiments are usually aimed at finding a cure to some disease that humans and certain animals have in common or at exploring how a biological organism works. During the experiments, scientists usually keep animals in cages and use them in laboratories where they harm them on purpose (“What is animal testing,” 2016). Moreover, there are certain kinds of experiments that cause animals a lot of pain, and, in many of them, animals die.

The most common type of an experiment on animals is feeding them with certain substances and injecting them with experimental medications. After the procedure is completed, scientists observe the effects that these substances have caused. In fact, the result is often unpredictable, and animals can die a horrible death with much pain. Another type of experiments is exposing animals to toxic substances and radiation. These experiments are primarily aimed at discovering the effects that radiation and certain chemicals can have on a biological body. Similarly, such experiments make animals suffer (“What is animal testing,” 2016). Moreover, if animals survive after such experiments, the damage that radiation and chemicals have caused to them is often permanent, and they will live the rest of their lives suffering.

One more type of experiments on animals is dissecting animals while they are still alive. Certainly, during this operation, they are under anesthetics, but it does not justify the result that they get after the procedure is completed. The main reason for these experiments is to find out how the internal parts of the biological body work. This operation usually involves removing internal organs, pumping out blood, and excising parts of tissues, which makes animals cripples afterwards. Additionally, there is one more type of an experiment that is usually practiced in laboratories. This is a psychological experiment that involves placing animals in situations and conditions which cause them to feel fear, anxiety, or depression. Such experiments are usually aimed at identifying the principles of animals’ behavior and comparing it to that of humans (“The five worst animal experiments,” 2014). Nevertheless, after these experiments, animals usually become very aggressive and cannot normally function in their animal “society”.

According to most religious laws, animal testing is forbidden, as they are defined as the same creatures as humans. Certainly, animals are not as smart as humans, and their perception of reality is different, but they have similar bodies and experience similar feelings. Therefore, before making horrible experiments on animals, humans must think what it would be like if they were experimented on (“The Muslim view on animal,” 2017). Thus, animals have the same right to live their full lives as humans.

Although human laws impose a certain restriction regarding the experiments on animals, they are not enough, as they still allow people to torture them in the experiments. According to European legislation, all vertebrate animals including reptiles, fish, birds, and mammals and only some invertebrates such as octopuses are considered “animals”, on which it is prohibited to experiment (“Treatment of animals,” 2016). In the USA, the situation is worse and such creatures as mice, amphibians, birds, fish, and rats are not defined as “animals”, and scientists can freely perform any experiments on them that they want.

The system of experimenting on animals has grown into a multi-million dollar industry that has many facilities and laboratories around the world. They also have special facilities aimed at breeding animals specifically for testing. In these facilities, animals usually live in bad conditions being imprisoned and forcibly fed. Using wild-caught animals is prohibited in Europe and in some other countries, but it is allowed in other countries of the world. It is usually forbidden to use such domestic animals as dogs and cats in experiments, but, unfortunately, not in all countries (McKay, 2016). Even monkeys that resemble humans the most are often used in experiments.

In terms of animal suffering, The EU even introduced a scale which measures the degree of suffering experienced by animals in a particular experiment. Thus, they distinguish between “minor”, “moderate”, and “severe” suffering inflicted on animals. For example, in 2012, in the UK, more than 60% of permissions were granted by the British government allowing animals to be undergone from moderate to severe suffering. Reportedly, approximately 75% of the experiments were performed without injecting the animals with anesthetics. Moreover, quite a big percentage of those experiments required animals to die (Scheler, 2017). For instance, the tests for various vaccines and chemicals resulted in the death of more than 50% of the animals involved in these experiments.

The second argument against animal testing is that it is often ineffective, as the results received from the experiments can be inaccurate. There are many reasons for this, but, the most important point is that in such science as medicine, the information must be reliable; otherwise, there is always a risk that a particular medicine will cause unpleasant effects in humans or even be life-threatening.

Despite being cruel and inhumane, the experiments on animals often turn out to be ineffective. The main reason for this is that the animal organism either responds differently to many life-threatening diseases that humans suffer from or is completely immune to them. For example, animals do not suffer from most heart diseases, some types of cancer and HIV, they do not have Parkinson’s disease and the majority of psychiatric diseases such as schizophrenia. However, some of these diseases can be artificially induced in them for the sake of an experiment that allegedly shows how these diseases can be cured in humans. Thus, the most important argument is that in these experiments, people usually do not take into consideration other factors that are inherent only in humans and affect the behavior of diseases (“Cruelty to animals,” 2017). These factors include socio-economic conditions, genetics, psychological issues, and personal experience.

Indeed, according to the statistics, quite a great number of experiments on animals, that were promising in terms of finding a cure to some diseases, turned out to be ineffective for humans. In this respect, the end does not justify the means, as animals suffered for nothing. As a result, animals’ lives along with the time and money were wasted, and no effective treatment was developed (“Arguments against animal,” 2016). In addition, as it can be seen, after the decades of animal testing aimed at finding a cure for Alzheimer’s disease, stroke, AIDS, Parkinson’s disease, diabetes, and cancer, there is still no reliable cure and effective treatment for them.

Thus, according to the statistics, the majority of experiments on animals that show promising results, turn out to be ineffective when it comes to humans. Moreover, the experimenting on smaller animals such as rabbits, mice, and rats showed an even lower rate of success, primarily because their organisms differ from that of a human (Scheler, 2017). Additionally, statistics show that only 20% of experimental drugs used on animals are effective in humans. In terms of testing the safety of drugs, only 45% of experiments work for humans.

According to the overall results of the experiments on animals conducted all over the world, approximately 120 million animals are used in them, and only about 30 new medications are approved every year, which is far from being efficient. The investment of the U.S. drug industry in the experiments equals $50 billion each year, but the approval rate has not changed since the 1960s. Among those drugs that are approved, not all of them are completely effective for everyone due to different individual reactions (McKay, 2016). Overall, for the last 20 years, only five percent of experiments performed on animals resulted in a successful approval of treatments.

Sometimes, animal testing can be dangerous even for humans. A vivid example is a drug called Vioxx that was used for arthritis. After successful experiments on monkeys and on some other mammals, this drug was approved for human usage. However, Vioxx turned out to be dangerous for humans causing more than 300,000 heart attacks all over the world, almost half of which resulted in the lethal outcome. Another example is fialuridine, a Hepatitis B drug that was prohibited for having caused liver damage resulting in five deaths. However, this drug had been several times tested on animals before. One more illustrative example is a monoclonal antibody treatment (TGN1412) that was tested on human volunteers. As a result, it caused an allergic reaction, after which the volunteers were hospitalized (Haugen, 2000). However, this drug had been used on monkeys several hundred times before, and no side effects were identified.

Banning animal testing does not necessarily mean that the development of medications that can provide treatment for incurable diseases will stop, as there are always alternatives, which can improve progress in medicine and add humaneness to the science. Thus, with technological developments in the sphere of science, the number of alternatives to animal testing is increasing. In this respect, the main problem is that most people are reluctant to use new technologies (“Animal testing 101,” 2016). Instead, they tend to stick to more conservative and traditional methods that certainly involve animal testing.

Another obstacle in the process of adoption of these new methods is bureaucracy. There are a lot of organizations and charities that advocate for the prohibition of animal testing, and they can accelerate the process of implementation of these innovations.

In terms of the alternatives, there are several of them that are very effective. The first alternative is growing cells and other organic material in laboratories. Nowadays, almost any type of a human cell can be created in a laboratory. These cells are used in the creation of special devices that are called “organs-on-chips”. These devices can be used for experiments instead of animals. There were already several successful experiments conducted on these devices that involved observing the behavior of diseases and the effects of drugs (“Alternatives to animal,” 2016). Additionally, cell cultures are now the primary focus regarding the development of treatment to such diseases as cancer, AIDS, kidney diseases, and sepsis.

Another alternative to animal testing, which is not new though, is human tissues. Human tissues that can be provided by volunteers or extracted from dead bodies can be used in some kinds of experiments. Moreover, there are many operations such as cosmetic surgery, biopsy, and transplants that can serve as a reliable source of human tissues. Using brain tissues from dead bodies has also lead to a better understanding of such diseases as Parkinson’s disease or multiple sclerosis.

One more alternative to animal testing, the importance of which has been increasingly growing for the past several decades, is computer models. Indeed, the most powerful contemporary computers in the world are able to simulate many processes that would occur in a human body after taking a particular experimental medication. These virtual experiments are primarily based on the already existing data about a particular disease and its behavior in the human body and on mathematical, chemical, and physical laws integrated into this program of simulation (“Alternatives to animal,” 2016). Certainly, now, computer sphere is not powerful enough for complex virtual experiments, but taking into account the rate of its growth, it will be soon.

Thus, as it can be seen from the statistics, animal testing is cruel and in most cases, not effective. Therefore, it must be banned, especially now, when there are many innovative technologies that can be used as alternatives. Moreover, these alternatives have already shown great promises in being much more efficient than animal testing. Fortunately, the current tendency shows that these alternatives will be adopted in the near future, thereby bringing the end to violent experiments on animals.
