Already for Mota (1980), Some characteristics of the way can be used as elements that will guide the definition of the diverse uses of the ground. On the other hand, the knowledge of the ambient impacts of the diverse activities in an urban way is important in the disciplinamento of the use of the ground urban (MOTA, 1980, p.22). One evidences, that the urban one ahead in a new way of life, which appeared leaving stops backwards dreams of an inadequate model, goes of meeting with the contemporaneidade. Valley to emphasize, that the man continues living under a regimen tax for the power. When analyzing this Ribeiro question (2001) affirms that, the international system is complex and involves diverse actors. The ambient order can be considered international as a subsystem of the international system. It is multifacetria because she adds actors as enterprise groups, not governmental organizations, aboriginal states, peoples, resulting in a complex net of relations social and espacializadas dispersed, whose actors if find sazonalmente for occasion of the meetings of the parts of each international convention (RIBEIRO, 2001, p.02). He is possible to still observe, that the new way of life, in the urban environment, brings obtains new problems, as, the exacerbado increase of the cities, thus standing out, serious problems for the urban, ecological environment and for the proper man.
Moreover, he observes yourself that during century XIX he did not have as many cities as currently and, that the biggest urban centers were concentrated in countries that presented higher incomes. He still identifies yourself, no longer century XX, that the biggest cities also met in countries that possuam low incomes. For Ribeiro (2003), this geographic alteration results in the aggravation of the partner-space inaquality, generated for the extreme concentration of the wealth, that devastates the world contemporary and for limits of the natural base.
