A group of ideologists such as Griffin state that the entire ecologic system other than human being should be the main consideration when we met with problems. They insist that the harmonious balance between human and other species and their environment, the awareness of the world protection ,the encouragement of different ideas play a significant rule in solving the problem between natural resource and global environment ,in adjusting and coordinating the relationship between human society and ecosystem .
