I think cities will be better in the future.
The population of the world keeps growing, but the amount of arable land does not increase. Therefore, I think more and more people will move to cities for jobs. This will make cities more crowded, and many problems like traffic jam and environmental pollution will become worse. In addition, housing price in cities is much higher than that in rural areas. So a lot of people may choose to live outside cities where they can enjoy fresh air and peaceful life.
However, I still think cities will be better in the future. Because most people are living in cities nowadays and they also have their families there, they may not easily leave their city life and move to other places. The government has been making efforts to improve problems which result from the population increase, so i believe that there won’t be any more new problems in our future cities.
