Pollution is becoming more and more serious all over the world,especially the smog.The poisonous gas sent off by factories,domestic appliances and automobiles has made the air unhealthy for people to breathe.
There is no denying that automobiles or factories are indications of civilization,nevertheless，which cause the serious problem of air pollution. It is on doubt that there are other reasons lead to this air pollution.On the one hand,The weather plays an important role in the formation and disappearance of air pollution. This is mainly influenced by wind and temperatures. Air pollutants can be transported by wind, causing a pollution to spread widely. Rain can remove pollutants from air, causing soil and water pollution. Sunlight can aid the conversion of air pollutants to different substances.On the other hand,the trees had been cut down and little by little, the forest eventually disappeared.Thus,there is no green trees to absorb the carbon dioxide.Therefore,this is also a reason to causes this problem.so,who should be responsibility for this matter?At first,Government officials have the greatest responsibility because they failed to develop effective measures.secondly,Consumers are also partly responsible for air pollution.not only because the products they use have caused air pollution during their production and distribution,but also because heating of houses and offices causes chemicals release into the air.
In addition,scientists have warned that unless effective measures are taken， the problem of pollution will eventually get out of hand. In addition,environmental experts point out that increasing pollution not only causes serious problems such as global warming but also could threaten to end human life on our planet.For example,the smog will have a great influence for humans activity, possibly causes the traffic accident.besides,the smog can go deep into the lungs and even enter the bloodstream,which will lead to heart,brain diseases and increase the risk of cancer.
Indeed， the earth is our home and we have the duty to take care of it for ourselves and for our descendants.Actually，people are showing a real concern over the problem. For example， there is an increasingly loud voice from the public for firm action against pollution from automobiles. In my opinion， we should work out concrete solutions to the problem of pollution from poisonous gas given off by automobiles or something else. First at all,Public transportation system should be perfected.Therefore, people will consciously reduce the use of private cars.For example,the automobiles should be equipped with a device which can dispose of waste gas so as to prevent it from polluting air. Secondly,In the environmental protection, the participation of the public has made the enormous promotion positively. The citizen’s environmental consciousness enhancement have the great significance for it.Thirdly,For environmental agencies it is very important to determine exactly how an air pollutant spreads. Air is not a very complex medium. This enables us to predict the dispersion of air pollutants with computer models.Only in those ways,can we reduce the pollution of air and build a more wonderful world.
