It is strongly believed by some individuals that doing trial on animals is not good and it should be declared illegal by the specific authority. On the grounds that other believes it is vital to figure out scientific mystery. I would argue that experimentation on animals are appropriate to save human life though there would be some other way to test like chemical testing in research lab.
To begin with, though animal is a part of our ecosystem but saving human life is most important . From the starting age of human civilization there are several disease were found which spread extremely among the people and killed many of them. To save human life scientists has been inventing various medicines as well as vaccines to provide human body proper defense system. But at the early stage of producing medicines and vaccines the inventors were not sure whether it is safe for human body or not. A mass amount of human death will occur unless those medicines are not tested first on other species. For example , in 2021 the vaccine of corona virus was applied first on rat to making sure that it is safe for human.
On the other hand, there might be some alternatives to test these medicines such as chemical testing on lab. Because testing on animals may led the death or physical issues of animals. Chemical testing of a new variant of vaccine is very crucial for human body as well as preventing animal death .For instance , scientist are now forcing more on chemical testing of a new vaccine or medicine rather than testing them on animals .
To conclude, despite of testing on animals we can not say whether a particular medicine is safe for us or not besides we have to looking for chemical testing to save the animals.
