An increasing number of people flooding into cities is an unquestionable fact, some of the problems produce.

　　Firstly, cities become more and more crowded, putting much pressure upon employment, housing, medical care, transportation, education and so on. Urban public services are under tremendous pressure. Secondly, more and more serious environmental pollution, including air pollution, water pollution, noise pollution and so on.. Pollution has also caused people's living environment has become increasingly harsh, high diseases such as cancer, avian flu. Last but not least, the city is also threatened by rising crime. Television, newspapers, radio, the daily reported that a variety of homicide, robbery, rape and so on.

　　To sum up, Large influx of population is a two-edged sword, which brings us both conveniences and troubles. Of course, we should not give up eating for fear of choking. The best policy, as I see it, is to take advantage of its merits and eliminate its unhealthy influence so that it can better promote social development.
