When I was in middle school I was in a debate on whether it was “good” to test on animals. At a young age, I saw how mean it was and decided that I was entirely against it. That there was other models and studies that could be used to replace these studies. As an adult, I have realized that its many cases it is extremely necessary to conduct these experiments. I believe that it should be limited and must be seriously proven on why these studies are needed before they are conducted. Also as tissue engineering continues to develop I believe that one day the engineered tissues can replace testing on animal.
