I want to consider a relationship between humans and animals following last article. Basically I think it is only a relation whether eat or eaten as a living thing. Even more for human of eating everything, it is natural. I guess, in savannah if a human and a lion meet, the man would be killed and eaten soon. Therefore, I look down on vegetarians who say that animals are poor and terrorists who protest that whales should not be caught because they are wise than other animals. If there are not religious idea, socially-accepted idea and law, even we can’t predict its appearance. Therefore, I think it is important for us to eat everything with thanking them.
