The earth ecosystem has life characteristics by itself, and is able to maintain sustainable development through strong capability of self-regulate and self-control. This paper showed that in the biogeochemical process of silicon (Si) and Carbon (C), the earth ecosystem determined the phytoplankton growth by virtue of silicon, in turn by virtue of the phytoplankton growth determined the variation of atmospheric C. The power of the earth ecosystem was silicon, whose core was the dynamic balance of the temperature, and whose aim was the sustainable development of itself. In the furiously wrestling process between human being and the earth ecosystem, intensively brought would be a series of natural catastrophes, such as drought, desertification, sandstorm, storm, flood, mudslide, hillside, storm tide and red tide. Therefore, human being should bave to put up with and adapt to the climate change, to comply the controlling chain and the dynamic balance in the earth ecosystem, and to follow the laws of the variations in the earth ecosystem.
