Environmental Problem

Air pollution has become one of the most serious problems in China. With higher living standard, an increasing number of people are able to have their own cars. However, the exhaust produced by these cars is a big threat to the environment as it contains not only green house gases but also toxic gases such as sulfur dioxide. In addition, China's economy depends heavily on heavy industry and many factories simply release waste gases that have not been dealt with properly. More often than not, chemicals contained in the gases will do great harm to both human beings and other living things. In the past few years, there have been quite a few cases in which industrial waste leads to diseases and deaths. Moreover, due to deforestation, China's largest "air cleaner" has got into trouble. With much fewer trees, less carbon dioxide is "replaced" with fresh oxygen. All these factors contribute to air pollution. Before the problem becomes too big to handle, measures must be taken to reduce air pollution. For our government, strict laws and policies must carried out against releasing industrial waste directly. Forests must be protected and a certain number of trees must be planted every year. For individuals, using public transport should be encouraged. People should be aware of the present situation of air quality in China and know what they can do to improve the situation. In a word, we must unit together and solve air pollution problem for the benefit of, in fact, ourselves.
