Conducting research on animals for human purposes is something that has been practiced for centuries. However, this topic has become extremely controversial after numerous loud outcries from animal rights organisations such as well-known PETA, Mercy For Animals, In Defence of Animals, and many others. Society has become aware of some spine-chilling and alarming statistical analyses which show that only in the US, more than 25 million animals are used for testing purposes on a yearly basis. Such insight divided the world on those who accept the sacrifice of animals for the sake of enhancing human lives, and on those who are completely startled by the sheer cruelty and lack of humanity in the 21st century. And yet, it is difficult to be completely biased and think we should stop animal testing once and for all. However, in this essay, I will try to balance the controversy by outlining why such practices should be cut down significantly, but still kept in a certain percentage. First of all, it is important to mention that many human lives have been saved thanks to cures that have been first tested on animals. It is impossible to neglect the fact that there is a vast number of treatments and cures available, that wouldn’t have come to light if there hadn’t been series of experiments conducted on animals. Despite sounding unethical or immoral, we have to acknowledge that millions of lives have been saved. Immoral though it may seem, there is some logic in animal experimentation.
