I am in favor of the opinion that animals are used for scientific purpose.

Our science skills have been improved. the improved science skiles  have been a part of our life by developing facilities, radio communication, medicine...

At the same time, however, the scientific development leads to many things that menace our life. Fortunately, the animal experiment has prevent us from perilous things. operating animal experiment, our life’s security has been assured from these things. and pursuing better life is similarity of all creatures in the Earth. therefore, if you happen to regard this experiment as selfish thing, you deny nature phenomenon. so we accept animal experiment as a necessary method.
