bin, the developer of the oral vaccine to polio, stated that "paralytic polio could be dealt with only by preventing the irreversible destruction of the large number of motor nerve cells, and the work on prevention was delayed by an erroneous conception of the nature of the human disease based on misleading experimental models of the disease in monkeys."(PETA 1). Not only does animal experimentation have low scientific credibility, it causes great pain and discomfort to animals.One example of this is eye irritancy tests for beauty products. A rabbits eyes are forced open and clipped onto the forehead by the lids, the rabbit may break its neck or back trying to remove the clip. Over a period of time, usually over 3 days, the damage to the rabbits eyes is recorded. Pain relievers or depressants are not administered as this will interfere with test results. Though this is not necessary, the companies do this as a defense from being sued, claiming the rabbits were not greatly harmed, though the rabbits are killed 2-4 days after the tests. An example of animal misery is with the chimpanzee, the closest primate relative to a human being. These animals share 99% of the genetic composition of a human. From their birth (in laboratory conditions) they are isolated and kept away from other animals, not having contact with any human or other chimp. The loneliness that these animals feel usually drives them to insanity. Chimps are usually used in tests on AIDS, hepatitis, and other human diseases that are problematic. All animals that actually survive the cruel tests that take place for the name of science/beauty/etc are usually killed after the testing.Animal experimentation is a cruel, inhumane act. It costs tax money that could be put to better use, has not accomplished much of anything, has low scientific credibility, and causes great pain to the animals tested, all eventually dieing prematurely. This is a very old and outdated prac...
