Because people are negative effects on the highly developed industry expected is insufficient, prevention of adverse, led to the global crisis of the big three: resource shortage, environment pollution and ecological destruction. Environmental pollution refers to natural or man-made destruction, adding a substance into the environment and more than the environment self-purification capability and harm behavior. (or due to human factors, the environment is polluted by harmful substance, make the growth of biological and human normal life affected by harmful.) Due to human factors make environment, form or state change environment quality to drop, so as to disturb and destroy the ecosystem and human's normal production and living conditions.
Environment pollution can cause direct damage to the ecological system and influence, such as desertification, forest destruction, will also be an indirect damage to the ecosystem and human society, sometimes the indirect environmental effect of harm does more harm than was caused by the direct, and much harder to eliminate. For example, the greenhouse effect, acid rain and ozone depletion is derived by atmospheric pollution environment effect. This kind of environmental effect has a hysteresis derived from environmental pollution, often occur in pollution is not easy to detect or anticipated at the time, however, in the event of means have been developed to the point of serious environmental pollution. Pollution of the environment, of course, the most direct, the most vulnerable to the feelings of the consequences of is to make the quality of human environment, affect the quality of human life, health and production activities. The city's air pollution cause air pollution, for example, the incidence of people up, etc. Water pollution worsen water environment quality, the quality of drinking water has generally been declining, endanger people's health, causing premature fetus or deformity, and so on. Serious pollution incident brings not only health problems, but also cause social problems. With the increase of pollution and people's environmental consciousness, because of pollution caused by the crowd disputes and conflicts increases year by year.
At present to varying degrees on a global scale environmental pollution problems, have a global impact have atmospheric pollution, Marine pollution, urban environmental problems etc. With the globalization of economy and trade, environmental pollution has increasingly showed a trend of internationalization, the border of the hazardous waste transfer problems in recent years is the prominent manifestation of this line.
