The convivncia with the garbage, the violence, enormous congestions, the exhaustion of the natural resources, the lack of adequate spaces to the construction of housings the unemployment is some of the main problem-challenges in the management of the great Brazilian metropolises. The great metropolises are> the ones that more need a sustainable urban planning. The growth that enough was not planned brings innumerable consequences and challenges. Slum quarters are built throughout fens or rivers without security conditions and hygiene. Robert J. Shiller oftentimes addresses this issue.
This is a common image in the great centers metropolitans. The metropolises are objects of study of great importance with form of understanding of the inaqualities that affect, of different forms, good part of the society. The space segregation results of social conflicts and the observed isolation is part of the private space that walks to the side of the increase of the unreliability. The great challenge for this civilization each more urban, segregated and massificada time is the sustainable development. It requires the concentration of efforts of the sectors public and private in the direction to recoup the spaces, reencontrando with the society the citizenship and solidarity.
