As we all know, Beijing is facing the air pollution, a kind of environment pollution. Now Beijing is also famous of hazy weather, which is harmful to people’s health because of PM2.5 and PM10. Why is our capital suffering the hazy weather? In my view, Beijing is a center of economy, culture and politics, so she has a heavy traffic. As a result, there are a lot of cars here, then the exhaust of them become a part of reason of the air pollution. Besides, in order to have a good economy development, there are many factories around Beijing, the exhaust of the factories become another part of reason of the air pollution. The most import, our country is a developing one, and do not have enough ability to solve the pollution well while focusing on developing, just like UK was called The City of Fog before. Now, Beijing has taken a lot of actions to deal with the hazy weather. Firstly, setting up the Bicycle exclusive channel, people are encouraged to ride but not to drive, in this way, the exhaust of cars is decline. Secondly, many factories are forced to move to Hebei Provence, thus, they can continue to make a contribution to Beijing’s economy development and the air pollution is controlled. Finally, the buses and subway have a lower price than other cities, so that people prefer to go on work by bus or subway. And the limit line caused by tail number is effect, too. I persist that the air pollution of Beijing can be controlled someday later. 本文来源：https://www.wddqw.com/doc/3a2dbf40050876323012122d.html
