The air pollution is the most serious pollution in China
　　I think air pollution is the most serious pollution in China.We human being cannot live without air.Once the air is polluted,our health is threatened.There are two main atmospheric pollution sources:one is natural,and another is man-made.We can do nothing to control the former,but we can control the latter.Burning coal provides 75 percent of the energy in China.The waste air emitted from the coal burning contains a lot of sulfur elements mostly existing in the sulfur dioxide gas,which will turn into acid rain after a series of chemical reactions and changes.The using of agriculture poisons is another origin of the man-made air pollution.So we should use as less poisons in agriculture as we can and try to use some biological method to kill the harmful insects.
　　In conclusion,the main causes of the pollution of China are air,water,land and noises.Any kind of pollution has a bad impact on our daily life.Among them,I think,air pollution is the most pollution of China

　　Well,if you want to konw more about the pollution...
　　The main causes of the pollution of China:
　　1.The air pollution is the most serious pollution in China
　　2.The water pollution is another serious pollution that we cannot ignore
　　3.The land pollution and noise pollution are also parts of the pollution of China.
　　The main causes of the pollution of China
　　Peace and development are still the two themes of the current world.But as the world develops,more and more problems have arisen,among which is pollution,especially in some developing countries like China.Generally speaking,there are four kinds of pollution in China:water,air,land and noise.So what cause those pollutions in China?
　　Firstly,the land and noise are two parts of the pollution of China.The wastes on the land mainly include life rubbish and industrial solid wastes.Some materials are difficult to be decomposed such as plastic materials; although they can be decomposed,it will take a long time.The industrial solid wastes usually take a lot of room,and make our environment dirty and untidy such as slag or cinder and some deserted old machines.I think noises are the most annoying pollution.In recent decades because of all kinds of noises the average ability of people’s listening is declining more promptly than the past in China.People can not sleep well when the machines are still working at night.In day time the sound made by vehicles seriously affect the work of officers and the studies of the students,and destroy the quiet environment of some hospitals near the roads We need quiet.
　　Secondly,water pollution is another serious pollution that we cannot ignore.Water is,like the air,another basic substance of human life.But the fact is that more and more water is being contaminated.The available drinking water is declining.Some factories only pursue the development of their factories regardless of considering protecting the environment.They pour the wastewater into rivers and oceans as they like.Although sometimes they are forbidden and punished in China,after they are imposed a fine or forfeit they will continue to do as usual because the money they make by not adding some equipment to deal with the waste water is far less than the fine.In addition,the leak of petroleum,overproduction of some alga plants,and droppings from human and cattle are also apt to contaminate the waters around.
　　Finally,I think air pollution is the most serious pollution in China.We human being cannot live without air.Once the air is polluted,our health is threatened.There are two main atmospheric pollution sources:one is natural,and another is man-made.We can do nothing to control the former,but we can control the latter.Burning coal provides 75 percent of the energy in China.The waste air emitted from the coal burning contains a lot of sulfur elements mostly existing in the sulfur dioxide gas,which will turn into acid rain after a series of chemical reactions and changes.The using of agriculture poisons is another origin of the man-made air pollution.So we should use as less poisons in agriculture as we can and try to use some biological method to kill the harmful insects.
　　In conclusion,the main causes of the pollution of China are air,water,land and noises.Any kind of pollution has a bad impact on our daily life.Among them,I think,air pollution is the most pollution of China.
