You can also buy things from all over the world. But there are serious problems in big cities tool It is expensive to live there, and there are too many people in some places of big cities. Every year many people move to the cities to find jobs, to study at good schools and to receive good medical care. But sometimes these people cannot find work or a good place to live in.
