Tracy's animal rights homework

This discuss is disputable all the time. No matter agree or oppose experiments, they both have their reasons. So it is difficult for me to choose one.

First, I didn't agree with animal experiments. Because I thought human are also animal, human and animals are equal. Therefore, I don't think human have the right to do animal experiments. It is very cruel! I don't think human is more important than animals.

If we have not done animal experiments, all the medicine would not be produced. If we didn't have the medicine, we could not resist many kinds of disease. After I read the history of animal experiments and changed my angle to think scientifically, I could understand why we need animal experiments. We have no choice but to sacrifice particular animals to rescue some people who suffer from disease.
