Today's economy is developing rapidly, but it is not difficult to find that most of the rapid accumulation of economic wealth is at the expense of the environment. What are the causes of environmental pollution? The following is my analysis of the causes of environmental pollution for you. I hope I can help you.
Generally speaking, environmental pollution can be the result of human activities, natural activities, or the joint action of these two kinds of activities. For example, volcanic eruptions emit a large amount of dust, sulfur dioxide and other harmful gases into the atmosphere, which also pollutes the atmospheric environment. But usually, environmental pollution is more caused by human activities, especially social and economic activities. We usually refer to this kind of environmental pollution from human activities. The reason why human activities cause environmental pollution is that there is a fundamental difference between human beings and other organisms: in addition to their own production, human beings also carry out more large-scale material production, which is not available to all other organisms. Because of this, the intensity of human activities is much greater than that of other organisms. For example, for the utilization of water in the ecosystem, other organisms only use the amount that meets their survival requirements, while human beings do not know how many times more water is used than other organisms, so that all water in some local ecosystems is not enough. The emission source of pollutants is called pollution source. The situation of various pollution sources will be described in section IV.
Environmental pollution can be classified from different angles. According to the type of the polluted environmental system or the dominant elements, it can be divided into air pollution, water pollution, soil pollution and so on; According to the social field of the pollution source, it can be divided into industrial pollution, agricultural pollution, traffic pollution and so on; According to the form or nature of pollutants, they can be divided into waste gas pollution, waste water pollution, solid waste pollution, noise pollution, radiation pollution, etc.
In addition to the direct damage and impact of environmental pollution on the ecosystem, the accumulation, migration and transformation of pollutants will also cause a variety of derived environmental effects, causing indirect harm to the ecosystem and human society. Sometimes the harm of this indirect environmental effect is greater and more difficult to eliminate than the direct harm caused at that time. For example, greenhouse effect, acid rain, and ozone layer destruction are environmental effects derived from air pollution. This environmental effect derived from environmental pollution has a lag, which is often difficult to detect or predict when the pollution occurs. However, once it occurs, it means that the environmental pollution has developed to a very serious level. Of course, the most direct and easily felt consequence of environmental pollution is to reduce the quality of human environment and affect human quality of life, health and production activities. For example, city air pollution causes air pollution, people's incidence rate rises and so on. Water pollution worsens the quality of water environment, generally reduces the quality of drinking water sources, threatens human health, causes premature birth or malformation of fetus and so on. Serious pollution incidents not only bring health problems, but also social problems. With the aggravation of pollution and the improvement of people's environmental awareness, the population disputes and conflicts caused by pollution are increasing year by year.
At present, environmental pollution problems have appeared in varying degrees all over the world. The aspects with global impact include atmospheric environmental pollution, marine pollution, urban environmental problems and so on. With the globalization of economy and trade, environmental pollution is increasingly showing an international trend. The problem of transboundary movement of hazardous wastes in recent years is a prominent manifestation in this regard.
1. The plant's sewage, waste gas, waste smoke, waste residue and other toxic gases are filtered and discharged.
2. Try not to use private cars when going out to reduce environmental pollution caused by vehicle exhaust emissions.
3. Do not use disposable tableware and save paper.
4. Plant more flowers and trees and do not cut down indiscriminately.
Pollution prevention and control:
Every instance of environmental pollution can be said to be an alarm sounded by nature to mankind. In order to protect the ecological environment and maintain the health of mankind itself and future generations, we must actively prevent and control environmental pollution. If the environment is not protected, mankind will face extinction.
Air pollution prevention:
The collection of advanced technologies for air pollution prevention and control covers flue gas emission control of utility boilers, flue gas emission control of industrial boilers and kilns, typical toxic and harmful industrial waste gas purification, motor vehicle exhaust emission control, typical air pollutant purification in living rooms and public places, unorganized emission source control of bomeidikang environmental protection Technology (Shanghai) Co., Ltd., simulation and decision support of air compound pollution monitoring Most of the key technologies in eight fields, including cleaner production, are from relevant national science and technology projects or research achievements of independent innovation since the eleventh five year plan.
