Should animals be used for scientific or commercial testing? From at least 1948‚ animals are being used by the U.S space program for testing aspects of space travel. Animals are used to help in medical treatments‚ determining the toxicity of medications‚ checking the safety of products for humans‚ and other commercial and biomedical uses.

Is it normally acceptable to experiment on non-human animals to develop products and medicines that benefit human beings? New scientific research has cast grave doubt on the safety testing of hundreds of thousands of consumer products. Everyday products‚ from soft drinks to paints‚ contain numerous synthetic chemicals. Official assurances of the safety of these chemicals are based largely on animal experiments. But recent results from a consortium in America suggested such assurances may be worthless

Scientists use animal testing for household products‚ cosmetics and medical purposes. Using animals to test household products and cosmetics is not necessary but when it comes for medical purposes‚ it is crucial. Even then‚ experts argue that animal testing for medical purposes lead to wrong ideas and provide unreliable data. Other experts say
