-- Concerned about the environment and create beautiful community
With the Beijing Olympic Games draws near, there is growing concern about environmental issues.
China is facing the following major environmental problem:
1. Severe air pollution problems
In 1999, the SO2 emissions to 18.58 million tons, remained at a relatively high level, the economic losses caused by acid rain serious automobile exhaust caused major cities NOx, CO, the concentrations of ozone, occupation of a trend in photochemical smog; particle pollution is highlighted , the majority of the urban prevalence total suspended particulates (TSP)超标phenomenon.
2. Water pollution and eutrophication problems remain unresolved
Seven major river systems, lakes and coastal waters large and medium-sized water pollution to be controlled. 1999 seven major river systems, only 38.1 percent of the river sections to or better than surface water quality Ⅲ standard; 131 in the vast majority of major lakes are subject to different degrees of pollution, reached more than half of the rich business degree in 1998 and the Bohai Sea 2002 years in a row in the history of the most serious red tide, area reached 6,500 square kilometers, sustained for more than a month, the serious impact on mariculture and result in major economic loss; urban groundwater pollution, water pollution threat to micro-safe drinking water.
3. Hazardous waste management and control to be strengthened urgently
In 1999, the volume of hazardous waste proced 10.15 million tons, of which nearly 2 million tons of hazardous waste directly to the environmental emissions, hazardous waste pile accumulated stock estimated to have reached 650 million tons. This gave rise to environmental pollution incidents have increased, a prominent environmental and food safety issues.
4. Poisonous chemical pollution on the environment and pose a clear threat to human health
To semi-volatile and volatile organic compounds, hormones, such as polycyclic aromatic hydrocarbons represented by the micro-refractory toxic chemicals from water and soil pollution, through the proction of agricultural soil pollution into the food chain. Volatile organic pollutants into the atmosphere, enter the body through the respiratory system, has been on human health hazard.
5. MSW and instrial solid waste pollution
Garbage and instrial solid waste at the mping or unsafe mping, the harmful gases and leachate seriously polluted surface water, groundwater, and atmospheric environment.
6. Serious sources of pollution in rural areas
Rural pesticides, fertilizers, animal husbandry pollution, because of Large-governance difficulties. At present the utilization of chemical fertilizers only 30 per cent, a large number of pesticides and fertilizers run-off into the water body. 1998 manure proction of instrial solid wastes proced 3.4 times. Manure to field rate was only 30%, the majority of untreated directly into rivers, lakes, and seas.
7. Trend of deterioration of the ecological environment has not been effectively controlled
Due to soil erosion, desertification, salinization, such as acidification caused by land degradation further intensified; water balance disorders, rivers drying up, shrinking lakes, wetlands destruction intensified, frequent flooding disasters; ecosystems, biological diversity and biological resources was severely damaged and the increase in the extent of the damage against the increase.
8. Nuclear safety and radiation safety supervision and management of the task is arous
China's nuclear power facilities is the type of reactor, technology sources country, building sites
How to solve these problems? How to make every Chinese person to have awareness of environmental protection? Not very good, everyone has a need, the whole of China is another way. Simple publicity and ecation from the start, now the Chinese people, almost not much use, although we can often see in the news hookup on the students or volunteers to do the environmental protection activities, but this alone forces, but drop in the bucket.
First, the rapid population growth, economic development and scientific and technological progress, and have intensified the root causes of environmental problems. Therefore, solutions to environmental problems must be population control, strengthening ecation, improving population quality, and enhance environmental awareness, and strengthen environmental management, relying on powerful economic strength and scientific and technological progress.
Second, solutions to environmental problems must be considerable economic strength, namely, the need to pay huge financial and material resources, and require long-term efforts.
Third, we must strive to develop science, and apply science and technology to create energy-saving machines and the promotion of economic development cycle. Development of energy materials, such as wind, hydro, etc.. Application of scientific methods on the factory cleaner proction. Application of sustainable development concept, and look at environmental issues and appropriate use of environmental resources, not excessive use.
