my second essay From the information given in the above bar chart, we can see a striking increase in city population and small decrease in country population from 1990 to 2010. During this period, there was a dramatic increase in city population from 300 million to 650 million and a small difference in country population from 810 million to 690 million. At least two fundamental factors could have contributed to this phenomenon. On the one hand, with the incredible development of economic happening in China, City greatly expanded to improve the level of their economic. As a result, a growing number of baby bored in city. On the other hand, due to the growth of economic, the farmer was more and more wealthy, even rich than city’s people, so part of farmer buy a house to live in city. In conclusion, the great increase of population in city could be a double -edged sword. While the big population can encourage the growth of city’s economic, it also bring some problems to city, such jobless, crime, house and so on. I am sure that if the goverment organize our society wisely, we can sidestep those drawbacks while taking advantage of the merits.
