范文节选：However, depopulation is not the ultimate solution to overcrowding in urban areas; new problems may arise. Firstly, the need for public-sector dwellings is not eliminated. With the number of migrants to cities constantly increasing, the vacated places are quickly inhabited by newcomers, so that the government has to develop more land to build houses. Moreover, evicting people does not cut the demand for quality resources such as education, medical care, and infrastructure, which are clustered in city centres. If rural areas are incapable of satisfying those needs, some people may still choose to travel back to their urban homes, thereby creating more traffic flow on the limited road space. Furthermore, simply shifting buildings to regional areas does not weaken vehicle dependency, as long as accessible public transit and industry cluster are not developed. Since companies are further from their clients, providers and other contractors, greater traffic volumes are still likely to be induced by transporting raw materials, delivering goods and services, and travelling on business.
