Sustainable Development

　　As the technology develops constantly, more and more people start to advocate the point of sustainable development. Especially countries depend on oil and coal, they begin to realize this kind of ways are not sustained.

　　In the past, we gain some great achievements by sacrificing our environment. But now we pay a price for neglecting the importance of sustainability. We should learn how to develop our economy sustainably. But some officials just do it symbolically, and they only want to get a promotion by it. If we want to do it well, we must try our best to do it and care for the sysmaticness.

　　There is no doubt that people should account for the terrible environment. What humanity needs to be subject to the nature is so obvious. We need act for the nature. We should think about how to adjust to it.
