Many people don't like big cities. They see the large population of cities, and they are afraid. Many cities are growing very fast. They are "monster" cities. (A monster is a big, terrible thing.) In some countries, there are no jobs in small towns. People go to cities to work. For example, 300,000 people go to Sao Paulo, Brazil, every year. In China, about 183,000 people move to Beijing from the countryside every year.
