we see a newly emerging community: there are supermarkets, schools, banks and hospitals. A resident tells us, “Eight years ago it was still the countryside.” The history of reform and openingup is the history of rapid economic development; it is also the history of largescale urbanization of our nation.
I firmly believe that the advantages of urbanization are many. First, when more and more people flood into cities, the city is often becoming bigger and bigger and many people move out of the downtown area and into the suburbs. This trend of urban construction is beneficial to future city development as a whole. Second, it provides more development opportunities for big cities. With more and more people coming to the city, urban development is experiencing a new round of leaping forward.
Urbanization may also bring a series of unfavorable consequences. First, the farmland in the country is shrinking. Second, sometimes, the rural land, rivers and air are polluted. When more and more new factories are set up, the surrounding environment is likely to decay. In my mind, it is not necessarily the result. Finally, the young people who still practice farming are becoming fewer and fewer. Some of them go to big cities to pursue a better life. Some of them stay at home, but begin to do business or work in local factories.
All in all, urbanization brings more benefits than problems. The present society is experiencing great changes—what we should be sure is that we strike a balance between economical development and environmental protection.
