Air pollution

Last winter, fog and haze weather has occurred a lot of times in Beijing. This kind of air pollutant come from a variety of natural and manmade sources.

Natural sources can include windblown dust, and soot from wildfires. Manmade sources can include motor vehicles, and industrial fuel burning, and manufacturing operations.It is obvious that fog and haze weather has many negative effects. First of all, people ’s health is threatened and some of them even suffer from diseases such as coughing and sore throats. In addition, increasing number of traffic jams and accidents arise from it, which in turn disturbs people’s normal life. In my opinion, the number of cars in Beijing should be limited. We should call on the people to use more public transport. Only in this way can we expect to have more sunny days.
