Without animal testing, the cure for polio would not exist and diabetics would suffer or die from their disease. Despite these benefits, some people believe that animals should be not be used for testing medical techniques and drugs. This essay will outline the advantages of animal testing.

　　Animal testing allows scientists to test and create new drugs. Animals such as monkeys or rabbits have similar physical processes to humans. This allows scientists to test the effects of certain drugs. If a drug produces adverse effects in animals it is probably unfit for human use.

　　Animal testing is cheap. There is a large supply of animals for medical research. Animals are easily bred, and maintained safely in controlled labs. The costs of testing in humans would be extremely high.

　　Many people argue that animal testing is cruel. In some cases this is true. However it would be much more cruel to test new drugs on people or children, or to let people die because there was not enough information about a drug. Furthermore, legislation in most countries sets standards for animal treatment, and laboratories have guidelines to prevent cruelty.

　　Opponents of animal research also say that information from animals does not apply to humans. They point to certain commercial drugs which have been withdrawn because of side-effects in humans While it is true that animal systems differ from human systems, there are enough similarities to apply information from animals to humans.

　　Animal rights campaigners claim that we dont need new tests because we already have vast amounts of information. However, many new deadly infections appear every year and new treatments and drugs are needed to combat these deadly plagues.

　　Animal testing is needed in the world we live in. Our responsibility is to manage the animals in our care and balance their suffering against the good that comes from them. 321 words
