And some countries make laws to control people do not hurt animals. Some people think that animal testing is very vertical method for human. It can help people to develop the science, the medication, the environment. For another’s, they think people cannot treat animals. That is very merciless. However, I think animal testing likes a sword has two blades. Animal testing has positive side effect on biology, food, medication, cosmetic and other chemical products. But animal testing have some negative side for people and animal per se.

On the one hand, animal testing is helpful for people to observe biology of species. Scientists can discover some cells assist human to develop the medication, and make more rapidly than before. For example, Madison at UW finds embryonic stem cells from monkeys and human. It is a revolution about biology (UW Animal Research Achievements, 2011). There also has induced pluripotent stem (iPS) cells. IPS cells are still in use worldwide to explore basic biology and animal development now (UW Animal Research Achievements, 2011).

It is very essential that animal testing can assist people to check our food. The scientists utilize animals to investigate the safety of food. There are all kinds of food people need to eat. And plenty of foods are pernicious for people. Researchers can use animals like mouse or rabbits to feed them different food long time. At that time, they observe the active of these animals. If animals emerge some actions that harmful for themselves, the new food cannot sale for people. Also I think everyone knows that food additives are a serious problem in modern society. Food...
