Response Questions : medical testing & animal testing on cosmetics

1.
Why do we use animals as Animal-Based Science? I think it must have its necessity. It's apparent that scientists don't want to hurt human beings, so they just experiment with drugs on animals. First, We have to believe some experiments are necessary, and they can't be substituted. Then, an appropriate animal based science doesn't cause intolerable pain on animals. Finally, if we do the suitable experiment carefully, people will work out the plan of animal based science and take care about animal's rights. They are all positive thoughts.
On the other hand, those experiments are always controversial issues. " Should animals have to be suffered for human? " " Will killing animals be a bad habit to make us more brutal? " " Are there any solutions to replace animal science? " Because those researchers have been trained to regard animals as tools, they take animal's pain for granted and they even don't feel guilty. However, there is no doubt that the animal science brings us a lot of benefits.

In my opinion, those cosmetics company want to save their cost to be the least, so they must use some inhuman experiments to produce their cosmetics. Of course, it's not a good idea at all. I know that, but in the meanwhile, we should think about how we can do to reduce those cosmetics. We can see so many companies which produce cosmetics with animal testing. Everyone has sympathy if they are human beings. We can't avoid this issue because we are customers who are also the murders.
Although using cosmetics is the necessary evil to modern people, I believe there are some companies do a successful model to exclude animal testing. Maybe other companies can ask those good companies how to do that. Well, sometimes it's a secret to those good companies. :P
I don't want to use those cosmetics with animal testing. Even if I don't want to be one of the animal killer, I can't afford the expensive cosmetics. The spirit is willing, but the flesh is weak. Nevertheless, I do agree with protecting animal rights. If I have abundant money, I will buy non animal testing cosmetics.
