The development of industry has brought prosperity to Taiwan, but has also caused some serious pollution problems. For example, the air pollution, water pollution, and noise pollution. The government and the public should be responsible for solving these problems. How we control the pollution? First, encouraging people to use unleaded gas to reduce the vehicle exhaust. Second, to concern with the water pollution, we have to use the waste of chemicals more carefully. Third, for the noise pollution, we must prevent drivers from honking at the midnight or turn on their music loudly. But, only by strict laws can prevent people from producing pollutions. It is really important to control the pollution.
