The US alone uses about 26 mio animals to test on each year. Laboratories use animals to test medicine or check the safety of cosmetic products.
Some people say that animal testing helped to develop life saving treatments and medicine and say that there is no other method to test on.
Others say that it's inhumane and cruel and that there are other methods to test products. Also, animals are not humans and animals could react differently on these tested products than humans.
No animal should suffer the cruelty these test animals suffer. These are sentient living creatures who don't deserve mistreatment the same as we don't deserve it. What these laboratories do to these animals is beyond our imagination and simply evil.
How do you see that?
