【正确答案】[范文] Air Pollution
The air pollution does harm to people. It causes people to suffer from some illnesses such as headache and cough. What's more, it affects the environment, too. For example, in some heavily-polluted areas, plants do not grow well or can't grow at all.
However, something can be done to solve the problem. First, we can develop a good public bus transportation system to reduce the number of cars on the roads. Cars are the main source of air pollution in many places. And second, we can move all the pollution-causing factories out of cities.
In summary, there are lots of things that should be done to prevent ourselves from the air pollution.
