Pros & Cons of Animal TestingAnimal testing – taken here to mean the use of animals in research for the purpose of furthering human concerns such as drug efficacy and the safety of products such as cosmetics – is an endeavor fraught with controversy and difficult ethical arguments. Animal experimentation has clear and undeniable benefits to humankind; for example, the development of drugs to combat deadly diseases. At the same time, some types of testing subject animals to cruel and inhumane procedures, offsetting, in the eyes of animal-testing opponents, any benefits of animal testing to humans.
