A great amount of information that is found by animal testing is useless, a waste of money, time, and lives of innocent animals. On the other hand, research on animals is an important factor in understanding disease and developing ways to prevent it. Millions of people's lives have been saved because of the efforts put forth in experimentation with the use of animals. Animals are sacrificing their lives for humankind, which they owe nothing. Every year about 60 to 100 million animals are used for experimental testing. Scientists use animals such as: birds, cats, dogs, guinea pigs, hamsters, monkeys, and rabbits (Why Vegan 13). Scientists study the animals to get a better understanding of the body functions. Animals are also used for the development of new drugs and surgical techniques (Singer 19). Biomedical research, toxicity testing, diagnosis of disease, and product safety are also part of the big world of experimentation (Catalano 29). Scientists believe that these experiments that are pursued on animals are the main staple in progression of human medicine, health and safety. Such tests help determine if human beings might benefit from the new drugs or procedures. Although some animal testing has helped improved the quality of life for humankind; but has anyone thought about the animals who suffer and the experimentations and testing that are conducted on them are worthless? One argument against medical research on animals is the extreme cruelty that an animal undergoes during testing. For example, when foxhounds undergo lung experimentations, 68 percent of their lungs are removed. Another argument against medical research on animals is the inconsistencies of the effects that a drug tested on animals will have on humans. A third argument against animal testing is that there are alternatives ways to experiment, which are cheaper and the animals will not have to undergo these extremely cruel tests.
