City Problems
Nowadays, millions of migrant workers flock into cities in search of jobs and better
living. However, with the sharp rise in the urban population, many problems arise in t
he development of cities.
Firstly, cities become more and more crowded, putting much pressure upon transportation, housing, sanitation, education, employment and so on. City services and facilities have been strained to a breaking point. Secondly, a growing number of private cars emit huge amount of carbon dioxide, leaving the air mercilessly polluted. What is more, the city is also threatened by rising crime. Not a single day passes without the report of someone being robbed, kidnapped or murdered. Last but not least, city-dwellers are not only separated from the natural world but also isolated from each other, even not knowing the name of their next-door neighbor.
All these problems have harmed the attractiveness of the city. Unless there is some improvement, more and more people may seek to live in the suburbs.
