reaction on Sherry's Videos

when i saw these two videos, I felt that my heart was hurts, and there are two reasons. The first reason is these statistics, I never know that everyday there are about 5700 people die from AIDS and 7.6 million people died from cancer during 2007. This really surprised me. And the second reason is because of these animals. We use their lives for our own purpose. We never care about their feelings, when we do the research. On one hand, we have no choice, because so many disease are come from animals, and these disease are affecting our health, so we have to find the treatment for these disease, or we all going to die. But I think animals also have their rights, we can not take their lives, just because some tests or researches. however, on the other hand, animals also can get benefits from these tests, they can evolve themselves. Someone said that get something, lose something. when the animals lose their lives, they also get a chance to evolve their specie.
