　　The Impact of Air Pollution

　　The cartoon vividly reveals the phenomenon of air pollution or the decline of air quality.In the cartoon we can see the air pollution is so serious that the earth can't bear it.

　　What exactly contribute to this phenomenon? Possible reasons can be listed as follows: firstly, vehicle exhaust gases could be one of the most leading causes. With the improvement of economy and people's living standard, urban inhabitants in mounting numbers own their private cars. More automobiles will inevitably generate more exhaust gases. Additionally, household appliances widely used in cities also release a great amount of carbon dioxide gases, which further intensifies air pollution. Last but not least,many factories around the cities emit large quantities of untreated poisonous gases, which should also be responsible for the decline of air quality.

　　Definitely, air pollution will exert a detrimental impact on many aspects of people's life.For example, many diseases such as cough, skin problem and lung cancer are caused by it. Perhaps it is high time that we should adopt some measures to solve the problem of air pollution.
