Environmental policy aims at putting environmental resources, such as land, water, air, the atmosphere regime, with clear and enforceable rules. The tools various forms of restriction on activity: access to these resources may be limited, for example, by placing limit values on emissions or their use may be limited ( by restricting the kind of activities allowed in natural habitats or drinking water reservoirs) or make subject to specific conditions ( such as paying a tax or an environmental levy or the obligation to clean and recycle them after use). Rising incomes and rising pollution have brought with them a rising demand for environmental protection of policies. Market forces themselves have led to a reduction in the pollution in intensity of economic activity of the dynamic growth of the " cleaner" rates of return for local and regional pollution are closer to social rates, then for global commons. However, policy action has nevertheless been strong needed to decouple economic activity and emission levels. In fact, environmental policies cause an adjustment of economic structures. The price of using environmental resources and of exposing the public to health risks should be brought closer with social cost, with consequence that pollution and risks to public health should decline and GDP becomes less pollution intensive. Besides, polluting industries will be held in check when cleaner industries will be boosted and net effects on welfare though not necessarily on economic activity as measured in national accounts statistics. This adjustment comes at th price of fiction between regulated industries, their supplies and customers which could offset potential welfare gains. A cost effective environmental policy should aim to minimize costs incurred in achieving an environmental objective by dynamic character of adjustment needs and cost and benefit can be estimates in the absence of well functioning markets. In this way, it could contribute to significantly relaxing potential trade off between environmental protection and economic growth aim and supporting welfare enhancing structural adjustment.In conclusion, in the future, environmental behavior change will be limited by unclear solutions and low political profile, but models of human behavior can help in understanding how to support change. I shall recommend three methods to solve environment pollution challenge to influence economic growth for long term at the same time.The first point, it is practical for example, governments need to promote teaching behavior to let their countries' citizen to know the corrective attitude to putting rubbish to rubbish boxes in streets and to promote recycling schemes to achieve more environmentally friendly products. For example, Hong Kong have 7 million people are living in one small city. If HK citizen put their rubbish to any streets, gardens etc. public places. It will influence natural environment to be worse, then it will influence the flowers, trees plants and bees, butterflies, ants etc. insects which can not be alive, due to their natural environment has been polluted by HK citizen. Hence, human have responsibility to protect their natural environment to let any animals and plants can be alive safely and healthy. If our world could have health and good natural environment which can let human and animals and plants to be alive, then pollution can also be reduced, even our countries' economy can grow fast because product manufacturers can have good and beautiful places to let them to build their plants to manufacture their products every day, due to good natural environment will provide good places to let manufacturers to build their plants, then their workers will also have good health to do their jobs in their plants to raise their productivity and work efficiency.
