If the city residents over want to improve living quality, the problem of air pollution has to be
solved. With more and more factories being set up, plenty of people flooding into cities and a great
many cars and buses running on the roads, this problem has been much more serious.
First of all, big factories should abide by the environmental laws and rules closely, not giving off
waste gases into the air directly without disposal. What's more, the municipal government should
call on the community to plant more trees, which can purify the air and improve air quality. Finally
the tail gases from cars, buses and trucks should never exceed the national standard. Only when
all the people stop pursuing personal interests at the price of air pollution can we hope put an end
to this unfavorable situation.
The air quality is of great importance to anybody at any time and place. If a person refuses to
learn cooperation and discipline, how can we enjoy the privilege of higher living quality?
