Sustainable Development Sustainable development refers to economics, social, and environmental protection, coordinated developments of resources, which is an inseparable system. It is necessary not only to achieve the goal economic development, but also to protect the atmosphere of human survival, fresh water and land and other natural resources and the environment. Only after having done like this, our offspring can live and work on and on in a peaceful,stable and sustaintable environment. It has two main characteristics----development and constancy. The former is the premise, and the later is the key. There is no need to discuss constancy and the same on verse. Economic growth is the basis of development, and it aims to achieve the goal of man’s benefits and overall social progress. On the other hand, there is a limited capacity of bear of natural resources and environment. The combination of a lack of sustainable and economy consists of the limitation of economic development. And compared to ours we should think more of the interest of our descendants. These two exist side by side and play a part together, which forms the body of sustainable development. It gives consideration to both short-term and long-term goals and interest and overall harmony development of economy, society, resources and environment. It relates to every aspect of human society and means the completely reform of society. Environment protections can’t go on without economic development due to a large amount of capital. While it equals committing suicide if men just take care of economic development instead of environment protection. Our plundered demand from the nature today will lead to the drain of resources and the seriousness of environment deterioration and the disappearance of human being, let alone the economic development.
