Nope, 100% no, not under any circumstances.
I'm sure the majority of people agree that using animals for cosmetic purposes is wrong, shoving corrosive **** in a bunnies eyes because you want shimmery eyelids is beyond disgusting. I also think it's wrong for medical research, what gives humans the right to use animals for our benefit? It just seems so morally wrong to me, knowing that every medication I take was tested on animals, potentially killing thousands or even millions of them, makes me feel so guilty and uneasy, why should they have to suffer just so I can have the privilege of taking medication?
(not saying people shouldn't take medication, if you need medication for whatever reason, you should take it, i have nothing against people who take medication it just disgusts me that it has to be tested on animals by law.)
Humans have advanced in so many ways, look at all the technology we have now, we can do so many amazing things with technology, yet we still test on non-human animals to research human illnesses? It's absurd to me, there's no need for it. There's many, many alternatives to animal testing now, such as human stem cell research (from donations), as well as humane research on people who have said disease. There's even artificial human skin, such as
Episkin who recreate many types of human tissue for research purposes. Other alternatives to animal testing include;
Computer (in silico) Modeling, in vitro (test tube) testing on human cells, image testing through MRI and CT scans and many more. With all these options, why do we still test on animals?
In the UK all medicines have to be tested on animals before they can be sold and approved for humans, it doesn't make sense, just because we have similarities with certain animals does not mean that we are the same nor does it mean that a drug safe for animals will also be a drug safe for humans. Many times testing drugs on animals has failed and caused harm to humans,
here is a list of 50 times animal testing has failed humans, I'm not completely sure how reliable all the information here is, but it's pretty common knowledge that animal testing has failed humans many times. Even if it did work 100%, why would it be acceptable to kill billions of animals like that for our personal gain and development when there's so many other viable options?
