In recent years, experimenting on animals has become an issue that more and more people feel very strongly about. Scientists claim they need to do animal testing. In my opinion, this is simply not true. Most of these tests are not needed and cause unnecessary pain to animals. Animals, like people, have rights. Animal testing is wrong for several reasons. First, computer models can check the safety of new medicines just as well as animal testing. Second, animal bodies are not the same as human bodies, so using them in tests does not give good information about medicine for humans. Third, it is wrong to cause pain and death to animals. It is cruel to take baby animals from their parents to be used in tests.
