Brasilia has problems as a city. The city was made for half a million people. Now about two million people live in Brasilia.The poor people live in slums outside the city like in other Brazilian cities.It is not in the center of Brazil and there are few tree in the new city.There aren't too many people outside in the streets. some of the streets are very wide. They are really for cars. It is not easy for people to cross the streets.
