Animal testing is cruel‚ unnecessary‚ and disgusting. The results of most animal tests are rarely relevant to humans and are not reliable. It is unneeded in today’s society‚ considering our technological advancements. More accurate and scientifically superior methods are available‚ usually costing less and even being quicker to perform. There are methods such as using blood from human volunteers‚ using artificial human skin (proven by the National Cancer Institute to be a perfect substitute)‚ human

Animal testing Aristotle and Erasistratus were the first two early Greek physician-scientist performed experiments on living animals. In 1859‚ Charles Darwin’s evolutionary theory reinforced the conception that animals could serve as models for humans in the study of biology and physiology. Animal testing plays a large important role in pharmaceutical and medical advances‚ but many question the mortality of such use of the animal’s life. More than 100 million aninals are used for testing every single
