The result of this express process in the reduction, loss or same disappearance of properties, beyond the quality or productive capacity of the natural resources in face of the varied forms of pollution and production of a harmful environment that reaches direct or indirectly the health and the security of the people. Here it is the phenomenon of the ambient degradation, produced historically, as resulted of the social production of the space forms (p.104). The concept of sustainable development holds a paradigm rupture as the dominant representations on development. In accordance with Castro and Pinton (1997), translate, more necessarily, the necessity to exceed the dichotomy restored between nature and society as half to reconcile preservation of the environment and economic and social development. However, to collate, in planetary scale the problematic one on the environment with the question of the development is not an enterprise of easy reach when it knows that no model, until the gift, was susceptible to satisfy to these requirements (p.10). Any proposal of development will have to take in consideraes the ambient quality, stimulating the investments in the adjusted areas more inhibiting the program of high economic, social and ambient risk.

economic growth must have as inductive base the potencializao of the capacity of the traditional populations, from ethics of social development that it sends for the contour of the regional inaqualities and the ambient impacts. Of parallel and similar form, when dealing with the regional questions, comumente the process of formularization of politics does not take in account the available scientific knowledge, in the search for rational solutions for the problems. SACHS (2004) emphasizes that the sped up same growth that, is not synonymous of development if it does not reduce the poverty and if does not attenuate the inaqualities and also demands that if prevents the trap of spurious competitiveness e, in last instance, autodestrutiva, on the basis of the depreciation of the force of work and the natural resources (p.14).

In this direction, the city must be understood by the dynamics of the territory, for as if of its organization space, what it means a perception more dynamic, marked for the interaction of nets of communication and materialization of urban flows. It stops beyond describing given, urges to understand them. Ribeiro (2004: 22) affirm on the social segmentation its consequences when studying ' ' the population of eight regions metropolitans jumps in last the ten years of 37 million for 42 million inhabitants, and its peripheries know a tax of 30% growth, while the areas more central offices of the metropolises do not grow more than 5%. We have a period more each polarized time. After 1996, the per capita income in the Brazilian average cities increased in 3% and in the peripheries of the great cities it diminished in 3%. It has ten years the violence in the peripheries was another one.

They were committed about 30 homicides for 100 a thousand inhabitants. The Brazilian metropolises concentrate today, therefore, the national social matter and express the deepening of the divorce between the society, the economy and the Estado' '. The questions brought for Ribeiro is very bigger of what simply describing the data. One is about an analysis of the urban social problems and the paper of the State. A good content of geography demands, to if studying the city, the comment of the commercial areas, the historical center, the residential areas, the irregular occupation, the geographic exclusion and its correlation, allowing to the pupil the understanding of the value of the city and its space conflicts and contradictions. From the study thus lead the pupil she understands the meaning of the experience place, of the belonging, she reflects on standards of segregation in the management of the urban problems – they are of that nature will be -, associate ambient phenomena to the management of natural resources (water, sewer, sanitation, emission of pollutants, etc.), of preference comparing what she happens in diverse realities of other cities, states or countries with its personal experience.
