Should Animals Be Used for Scientific or Commercial Testing? Some say that animal testing is cruel and inhumane, but the testing has contributed to many lifesaving cures and treatments. The California Biomedical Research Association states that nearly every medical breakthrough in the last 100 years has resulted directly from research using animals. But some animals are very different from human beings therefore they make poor test subjects. Researchers have now found new ways to test products without using animals; by doing this the government is saving money. While some animals are similar to humans the results can still be inaccurate; hurting and killing these animals may be useless if the research done on them is for nothing. So is the risk worth taking? It is after all another life.
