Pro Animal Testing Animal testing has become a wide contribution in medical field in order to find new treatment, developing new medicines and improving the existing ones as well as testing the safety and effectiveness of new medicines. Some medicines development is depending on animal research, for instances, vaccines and insulin for diabetes and kidney transplants. However, there are many diseases that their cures are still undiscovered yet and one of them is AIDS (Tanir, 2012). Frankie L.

None of them could have occurred without animal research.” Therefore, this paper will discuss the importance of animal testing as well as how it plays its roles in medical field.
The Breakthrough in Medical Field
Researches on animals have been conducted since the ancient Greeks in order to advance human knowledge. Animal experimentation has played a part in many major medical advances, including the development of antibiotics, vaccines, and surgical techniques. According to McGuire, animal testing has helped in providing “antibiotics and vaccines, insulin for diabetes, treatments for leukemia, and has made possible advances in medical technology such as blood transfusion, kidney dialysis, and the heart lung machine” (“Animal Experimentation”). Thus, it is important to continue animal research because there is

Using Animals for Testing: Pros Versus Cons

By: Ian Murnaghan BSc (hons), MSc - Updated: 9 Mar 2018|*Discuss


There are many pros and cons to the practice of animal testing. Unfortunately, neither seem to fully tip the scale to a side that pleases everyone – including the general public, government and scientists.

Pros or Postives of Animal Testing

1. Helps researchers to find drugs and treatments:
The major pro for animal testing is that it aids researchers in finding drugs and treatments to improve health and medicine. Many medical treatments have been made possible by animal testing, including cancer and HIV drugs, insulin, antibiotics, vaccines and many more.

2. Improves human health:
It is for this reason that animal testing is considered vital for improving human health and it is also why the scientific community and many members of the public support its use. In fact, there are also individuals who are against animal testing for cosmetics but still support animal testing for medicine and the development of new drugs for disease.

3. Helps ensure safety of drugs:
Another important aspect to note is that animal testing helps to ensure the safety of drugs and many other substances humans use or are exposed to regularly. Drugs in particular can carry significant dangers with their use but animal testing allows researchers to initially gauge the safety of drugs prior to commencing trials on humans. This means that human harm is reduced and human lives are saved – not simply from avoidance of the dangers of drugs but because the drugs themselves save lives as well as improve the quality of human life.

4. Alternative methods of testing do not simulate humans in the same way
Scientists typically use animals for testing purposes because they are considered similar to humans. As such, researchers do recognise the limitations and differences but the testing is done on animals because they are thought to be the closest match and best one with regards to applying this data to humans.

Cons or Negatives of Animal Testing

1. Animals are killed or kept in captivity:
In animal testing, countless animals are experimented on and then killed after their use. Others are injured and will still live the remainder of their lives in captivity.

2. Some substances tested, may never be used for anything useful:
The unfortunate aspect is that many of these animals received tests for substances that will never actually see approval or public consumption and use. It is this aspect of animal testing that many view as a major negative against the practice, as it seems that the animal died in vain because no direct benefit to humans occurred.

3. It is very expensive:
Another con on the issue of animal testing is the price. Animal testing generally costs an enormous amount of money, as the animals must be fed, housed, cared for and treated with drugs or a similar experimental substance. On top of that, animal testing may occur more than once and over the course of months, which means that additional costs are incurred. The price of animals themselves must also be factored into the equation. There are companies who breed animals specifically for testing and animals can be purchased through them.

4. Animals and humans are never exactly the same:
There is also the argument that the reaction of a drug in an animal's body is quite different from the reaction in a human. The main criticism here is that some believe animal testing is unreliable. Following on that criticism is the premise that because animals are in an unnatural environment, they will be under stress. Therefore, they won't react to the drugs in the same way compared to their potential reaction in a natural environment. This argument further weakens the validity of animal experimentation.

Personal Choice

While there are numerous pros and cons of animal testing, the ethical aspect overshadows both of them, which means that emotion may be the ultimate determining factor in whether a person believes the benefits of animal testing outweigh the problems associated with the practice.

BumpADump you are a moron. Scientist are helping us out completely. They have saved lots of us by testing on animals. Yes some animals have died but really if they didn't animals would be running the world. So they ARE doing a good job, and you need to shut up.

SuperAwesomeBRO - 9-Mar-18 @ 4:53 PM

Well I can see your point there doc but honestly they are killing millions of animals just to see if they can a cure a sickness for humans. But if you really look into it more than half the test they do on animals don't even help humans out. So really all they're doing is killing animals just to find out they did nothing to help.

BumpADump - 9-Mar-18 @ 4:49 PM

Animal testing has lead to many life saving cures, sure you may argue "It's cruel and inhuman" If we didn't do animal testing we wouldn't be able to find life saving cures, such as when we tested on the cow We found a cure to smallpox, or the zebrafish who can help control metabolism,Also people probably will never change from animal testing because one it takes people to long to change,and get used to it. Two because it would probably cost even more than animal testing does. Finally because once they mastered this they would have to find the way to cure whatever, and they can't use animals for it. So if the plague came back and we weren't able to use animals we would probably all die.

Who ever said kill all the monkeys, I have one thing to tell you. Those monkeys are my bros and they don't deserve to die. I dedicate my time to save all the monkeys and this is what I get, they all die. So you better shut your mouth and leave my monkey bros alone.

did you know that inslin came from dogs pancreases being removed

Anoymous - 7-Mar-18 @ 12:31 AM

Well honestly think about it this way antibotics cure (almost) any bacteral infection, an that came directly from animal research.

Anoymous - 7-Mar-18 @ 12:26 AM

I hope that animal testers are reading this right now so that they know people (like me)hate them for all the animals they tortured. If you were involved in any un ethical testing just ask yourself why. Then think about yourself killing and torturing animals for some shampoo thatwon't hurt someones eyes. People are drilling holes in puppies heads with little to none painkillers just to test how a disease would react if it was directly placed into the brain. Some people are just sick and should be charged with murder for every innocent animals life they take.

mom - 5-Mar-18 @ 2:11 PM

Stop animal testing and find other alternatives, live and let live

Mann - 1-Mar-18 @ 2:14 AM

The people who support animal testing for medical use but not cosmetic use are hypocrites.

Student - 22-Feb-18 @ 7:57 PM

i wish people would stop being so cruel

turtle - 20-Feb-18 @ 5:41 AM

I wish people would stop using animals they use mice, chimps, frogs, fish why do they do that.

love cookies - 30-Jan-18 @ 8:42 PM

I would rekon that we should stop this Testing .because we are humen being .if we will do this.what diffrent us and animal. It is a sin

Bharti - 13-Dec-17 @ 1:58 PM

I personally believe that animal testing is ethically wrong, however, I am still in support of it. Yes, animals are in pain and suffer, but the benefits to animal testing are many. As previous commenters have pointed out, life-saving medications have been developed through animal testing. While the shampoo-test (I do not recall the exact name of it, but it involves albino bunnies eyes being held open, while the shampoo product is placed in their eye) is a source of nightmares, would you rather a bunny lose its sight, or another person? Animal testing is horrible and completely ethically wrong to me, it is still necessary until an equally effective alternative method is found.

Aulumn - 8-Dec-17 @ 11:57 PM

Wow there are so many things to take in from the comments and the actual article. This is one of the things that will always be debated as even though i myself am a great animal lover, would i willingly give my life up this second, the truth is... no but it hurts to know that animals are being tortured so we can look good.There is also the fact that without animals to test on how would we find cures for diseases or something like polio and leukemia. It is not just humans that benefit from this,animals do as well,because from this as vaccines for parvovirus in dogs and feline leukemia were made possible wholly from animal testing.Animal testing has also bought animals back from the brink of extinction. However there are some times when humans prove themselves to be absolutely sick like when they let animals be used to study the risein blood sugar levels caused by heating and animals skin temperature had reached 131.5'C *even though boiling point is 100'C* . Is it really worth all the misery and suffering or Who would you rather be alive : animals or you? To be honest even I don't know what I would choose.

Anon - 4-Dec-17 @ 8:32 PM

Thank you I used this in my report about animal testing and the articlewas very helpfulthere was so many pros and cons to animal testing but I decided to choice that animal testing was wrong becuase animals have rights

Student - 7-Nov-17 @ 3:20 PM

Animal testing is wrong in so many ways. Animal testing is a cruel and selfish practice that only benefits humans. It goes to show just how humans take advantage of anything they can because they believe they have the authority to control everything in their sight. Animals are being tested on products that they will never have any use for, and these products do not make a difference in their lives.Animals are not able to have a say since humans are stronger. This essentially means, humans are denying animals’ rights and are visualizing them as lesser beings.Testing products on animals is in many cases murder, we are letting them test products to see how harmful they are and what the effects will be, leading many of them to die. Animals are not our property, we should not be taking them out of their habitat, out of their lives, to use them in ours selfishly and unnecessarily. They should not be used for experiments, entertainment, or any other abuse towards them. Animal testing is like slavery- it is separating a group of living beings, it is using them selfishly, and denying their rights. Animal testing should be banned at all causes, and should never be subjected to the practice.

student - 6-Nov-17 @ 11:49 PM

Animal testing has a good cause if it is to find cures that save human lives. However, why do we need to test cosmetics on animals? Why do we need to test and risk hurting animals for something that humans don't need? This is my view on animal testing

TheRussianBagel - 26-Oct-17 @ 12:54 AM

test it on humans. there are too many of them, and 3 animals shouldn't be killed for one human.

science - 11-Oct-17 @ 6:40 PM

I agree with VroomVroomSexual on this situation no more animal rights, kill all the monkies

VroomVroomLyndie - 6-Oct-17 @ 3:58 PM

People clearly dont understand the benefits of animal testing. Educate yourself before you post about the 'poor' animals.

Student - 28-Jun-17 @ 12:19 PM

whats wrong with using organ chips, the chips succeed in finding a cure most of the time and then animals won’t be badly treated and be put through excruciating pain. the chips and identical to the human body so they are reliable.

Elly - 27-Jun-17 @ 7:58 PM

what is wrong with the world, animals can't speak for themselves, they feel pain. would you want to have shampoo in your eyes, someone to inject cancer into you and to wrap barbed wire around your heart to give you a heartattack, it isnt fair for an animal to go through this pain, just think, would you want to go through what these animals are going through? 95% of tests fail causing the animals to die.

Elly - 27-Jun-17 @ 7:45 PM

Thx,this was very helpful for my school homework and will really help me with my test on Monday :)

Dr.Blue - 17-Jun-17 @ 4:37 PM

Animal testing allows for new extraordinary medicines that help millions of people.

Kara-zor-el - 4-Jun-17 @ 6:21 PM

This website and comments are being really helpful for a class debate on animal testing coming up next week. Thanks!

Steph - 22-May-17 @ 1:49 AM

This is actually really useful for my debate coming up!

Student - 18-May-17 @ 12:21 AM

It isn't even tested on animals until a variety of other tests are made first. People don't understand this.
