As today's scientists make efforts to solve the seemingly unanswerable questions to issues like curing terminal illnesses or learning about different functions of our brains and bodies, about 7-8% of this published researched is performed on animals (Lilienfeld 69). In performing this type of research, the ethical treatment of these tested animals has brought forth a highly controversial issue all over the world. While some claim animal research has given us useful insight into the human mind and functions, opposers like the world-reknown PETA organization state on their wedsite that ".. animals have rights and deserve to have their best interests taken into consideration, regardless of whether they are useful to humans."
It is estimated that mice and rats account for 90% of the animals that are used in laboratory testing according to the S.O.S group at the University of Georgia's website. Among other animals to be experimented on are primates, guinea pigs, cats, dogs, rabbits, and various others. Some of the purposes of these animals are to test human medications to determine harmful side effects, or to inject them with harmful diseases or even cancer in order to try to find cures to these terminal illnesses.
With both sides taken into account, my view on this issue is with the PETA organization in that since animals do not have the ability to stick up for themselves and give consent to their bodies being used in experiments, this type of research should not be allowed. There are so many different types of new testing and scans that scientists have developed that can be used safely on humans like CTs, MRIs, PETs, fMRIs, MEGs, etc. that there should be even less of a reason to have to resort to inhumane practices on defenseless animals. My stake in the defense against this type of testing is also strong due to my ownership of an animal myself. Though my dog has never been tested on, I could never allow myself to think it's understandable or ethical to allow an animal of any kind to be harmed or killed for the purpose of proving or disproving someone's research.
