Animals are often used as objects for various experiments and test. Any new human disease medicines are first used on animals, the new types of make has to pass the test on the animals first and surgeons practice their skills on pigs and dogs. I don’t think animal test is fair to put through the risky experiments to ensure that the medicine or other products are safe for humans to endure. Who measures the importance of life? We kill animals to avoid risk ourselves; I think there are no legitimate reasons for that. Animals have to have rights just as we people do, because they feel pain and emotions and if they look different from us, that does not mean they do not suffer or are ready to die.
It is obvious that scientists have to test the new products, but they would definitely come up with more accurate results if they tested medicine and other products of humans, since they are intended for human use. For instance, when trying to look for a cure for a stroke, scientist mainly used rats for test purposes. Out of nearly a thousand tests only 30 have worked on rats and eventually only three worked on humans. In my opinion we could find the right cures much faster and easier if we test them on humans. By testing the cures on our own species we would have more information on our body reaction to different medicines, rather than make thousands of experiments on species that have bodies and DNA very different from ours.
