during the 15 days from new year’s eve to lantern festival, beijing was affected by smog for more than half the time, because of which people suffered a lot. on the road people drove slowly because they could not see clearly. people also suffered from many illnesses caused by smog.

the smog in beijing has been caused by many factors, in which the increase of cars in the city area plays an important role. the carssend off a lot of poisonous gases, which in turn adds to the already seriousair pollution.

in my opinion, the number of cars should be limited.we should call on the people to use more public transport. only in this way canwe expect to have more sunny days.
