Antibiotics, insulin, organ transplantation, HIV treatments and heart-bypass surgeries—it reads like an A to Z of medical progress. But the major progress has something in common: they were all developed and tested by using animals. Actually, animals are used for research in a variety of settings. Whether or not humans should use animals for testing purposes, however, is a controversial subject.
Animal testing allows researchers to develop new medicine and treatments, advancing the field of medicine and improving the health of society. For example, many drugs used to treat or prevent cancer, HIV, diabetes, etc, have resulted from tests performed on animals. Many advocators of animal testing support the practice for this reason, even if they do not support testing, cosmetics or other non-essential substances on animals. No one chooses to use animals where there in no need. In fact, animal research has contributed to 70 percent of Nobel prizes for physiology or medicine.
Animal testing also enables scientists and researchers to test the safety of medicine and other substances with which humans have regular contact. Drugs, for example , may create significant risks to humans, so testing them on animals first gives researchers a chance to determine their safety before human trials are performed. While scientists understand the differences between humans and animals, the similarities are considered significant enough to produce relevant data that they can then apply to humans. This, animal testing reduces harm to humans and saves lives, not only because the exposure to risky substances is minimized, but because some new medicine and treatments have positive effects on humans’ overall quality of life.
However, a significant number of animals are harmed or die as a result of experiments and testing. Unfortunately, many of the substances used on animal subjects never receive approval for human use or consumption. Those who oppose animal testing consider this a very important point , because saving humans from suffering is no excuse for the death of laboratory animals. Opponents also argue that animals are dissimilar enough from humans to make the results of animals tests unreliable. Related criticism is that testing causes stress in animals, meaning that they do not react to experimental substances in the same way that they might in natural circumstances, making the results of experiments less valid
Using animals as research subjects is also expensive because they require food, shelter, care and treatment in addition to the costs of experimental substances. Long-term or multi-stage tests can increase the costs of the practice as well. The actual price paid for animals is also worth considering. In this respect, researchers take on an additional burden.
