In a word , the environment of human life has already worsened day by day. The reasons of the worsening mostly come from the human own bad life style, disrespecting the objective law, eager for quick success,use of the earth resource without scientific plan ,and lack of consciousness pratecting the environment in design . So they destroy home by themselves,which not only harm human on contemporary, but also seriously influence existence of descendants.

    The environmental question is caused by people's bad design and life style to a great extent , which puts forward a serious question for a designer that designers should undertake the historical important task of environment protection.

    Industry has brought the disaster to world while creates a large amount of wealth for mankind . Industry design has accelerated the consumpition of the resource and energy resource and has caused enormous destruction to the ecological balance of the earth while creating modern life style and living environment for mankind.

    So as industry designers, setting up environmental awareness incarnates their morals and social sense of responsibility. Designers must be responsible for their own designs, and must take human health and blessedness , and harmonically coexisting of nature with the human as the rules necessarily obeyed in their own design.

    Designers must also master the necessary knowledege in material, craft, chemical industry, manufacturing,ect.,in order to be possible for avoiding to danger to environment causing by his design.

    The concept of "Sustainable development design"has epoch-maling meanings of humanity and real development of the world .It reflects the designer's morals and responsibility , and has already become the trend of designing development in the 21st century .Hence ,mankind's development made of traditional industrial civilization was turned to one of the modern ecological civilization. It is the coordination of social progress,economic growth and environmental protestion.

    Sustainable development is a kind concept of brand-new ethics,morals and values that people should follow. Its essence lies in fully utilizing the modern science and technongy ,exploiting green resources ,development constantly, impelling harmonious development between human and nature and pramoting inter-harmony of population ,resource and environment .

    Solving the problem of sustainable development is a change of technological innovation and behavior made.

    Sustainable development strategy is to solve the problem of meeting contemporary people's demands in maximum under the precondition of un-hurting several generations' demands of the future . It will realize the unity of the present interests and long-term interest and leave the development space for descendants.

    The question of the strategic consideration of sustainable development should include circulation, green energy and ecological efficiency.

    Green design comes from introspection on environmental and ecological disruption caused by design of modern technology and culture. Green design focuses on the balance relation of persons and natural ecology . Designers should consider the environmental benefits at every decision of the disign process, and try their best to reduce the destruction to environment.

    For industry design, the core of green design is "3R",namely Reduce,Recycle and Reuse.It is necessary not only to reduce consunption of substance and energy sources,and reduce letting of harmful substance,but also to classified reclaim, recycle and reuse products and parts conveniently.Green design is not only technical ,but also an innovative idea. It requires designer to give up some rat-fuck method excessively emphasizing at the style of products, and to focus on the real innovative. He or she would design the form of the products with more responsible method and make the products lengthen their wervice life as much as possible through succinct and permanent modeling.
