pollution control
there are many cause of pollution. let us have a look at some of them. first, there are so many cars in our cities, especially large ones. they give off waste, sometimes even poisonous gases. second, many factories, such as papermaking ones, let their dirty water directly flow into our rivers and lakes. third, farmers use more and more chemicals and pesticides. so, our fields are polluted.
of course, these pollutions are harmful to our health. some rivers have become undrinkable. some polluted food or vegetables can cause cancer and if we breathe dirty air into our lungs, we may fall ill.
now, some governments are taking measures to solve this problem. for example, our government is making a policy to punish the factories, which have made the huai river very dirty. also, our government is reducing the number of cars in beijing. i think all these are very necessary. if we all work hard, this problem can be solved in the future.
