People In the Earth

In today's news paper, I found two articles about animals. One is about the event that people helped a deer which was involved in the accident. and another is about the hardness of killing the increasing raccoon. When I read these news, I felt that we, humanbeing, is so selfish. When we look back the history of the earth, the big change was leaded by us only in the past century. 100 years ago, there were not so many buildings and roads, but now we are living with many technological machine. WE changed the environment of the earth and nature world. Today some people point out that we can't live in this earth forever because we changed the environment of the earth too much. How selfish we are!! Now we have to think about our influences on the earth seriously, and also effective actions should be taken as soon as possible to save this wonderful earth.
