Animal Testing

I have seen these two videos. They are showing us two different sides to the animal testing issue.
One video, which named Pro Animal Testing, supports animal testing to help people. Some people say that animal testing is good for human to find solution to disease. Nowadays, more and more people died from AIDS, HIV or H1NI. Animal testing can help people to find out how to treat these diseases.
The other one, which named Stop Animal Testing Now, is against animal testing. Obviously, this video suggests people stop animal testing. We should protect all species of animals from dying out. Ecological balance is so important to the environment. There are a lot of consequences if we destroy the diversity of animal.
In my opinion, I think we should protect animal and find another solution to treat disease. Even though saving people lives is very important, we cannot kill animals to save people. We have to find a win-win solution in protecting animals and saving people lives at a same time.
