The supporter of animal testing argue that many medical treatments and procedures have been developed from experiments on animals, a total ban on the use of animals will prevent a great deal of basic medical research and the possible production of certain vaccines. Experiments on animals assist in discovering ways to help people and other animals for the future. Animal testing provides scientists with important data to treat human diseases. Legislation in most countries set standards for animal testing and laboratories have guidelines to prevent cruelty.
Animal rights campaigner argue that animals have the right to live their own lives peacefully and we aren't allowed to meddle only them just because we can. Many experiments cause discomfort, suffering, harm, pain and death. There are other alternatives available: computer simulation can be used to observe the results of drugs on the animals. The opponents to animal research say that the result are not applicable to humans. They believe animal testing is cruel, inhumane and unethical.
