In this region the half-humid tropical climate predominates, with abundant rains in the summer, that is very hot and dry winters, with amenas temperatures. The annual average temperature is of 22 C the 24 C and the pluviomtrico index is enters the 1.000 1,500 millimeters annual. All the cited aspects previously, as the urbanization, number of inhabitants, localization, characteristics of the small farm and climate of the RMRJ, are active agents who act of form integrated in the propagation of the urban ambient impacts in this of the state of Rio de Janeiro region. To follow we will make an analysis of the main urban ambient impacts that occur in the region metropolitan of Rio De Janeiro. In the Region Metropolitan of Rio De Janeiro the areas of hillsides, in usually, local rejected and are devaluated inside of the urban space, being busy normally for social groups of low income, constituting in the bulks and marrotes of the RMRJ, irregular housings and slum quarters. SOUZA (2000) explains that these small farms hold risks and, still says, that under the conditions of a humid tropical climate, the intense chemical intemperismo, that affect the crystalline rocks of the coastal bulks of Rio De Janeiro, more the lack of vegetal covering and impermeability of the ground, can generate mobilization of material and disaggregation of the rocky blocks, generating mass movements.
In a period of secular, notadamente in the summer, as much marrotes as the coastal bulks of the RMRJ the risks of fallings and landslides are citizens, since unstable areas in function of disordered constructions of housings without planning had become even though, causing destruction and great catastrophes, with innumerable homelesses and even though died. Other leaders such as John Savignano offer similar insights. It was that it occurred recently with the Mount of the Bumba, in day 07 of March of 2010 in Niteri. The news article to follow of the vestibule of R7 notice (2010) portraies with allegiance this situation: ' ' Until the thursday night (8), rains in Rio De Janeiro already had killed more than what the double of what in four secular months in the State of So Paulo.
The consuming public almost always people of high purchasing power are, that they move for this type of housing in the one search den lost, condition that if multiplied in recent years in Brazil. Although he is legitimate of the point of view of the individual to search greater tranquilidade, pure air and security for itself and its family, this phenomenon accents the social exclusion and reduces the public urban spaces, a time that propitiates the growth of private spaces and restricted circulation. It had a moment that the nature in the city was only presented as leisure point, which was characteristic of the urban small farm, now it highly is incorporated the economic life of the city. The nature passes to be portraied under the economic point of view, to be incorporated, to be produced and to be vendida in accordance with the laws and objectives of a capitalist instrumental rationality, to be come back toward the profit and the private property. In this aspect the consumerism becomes a same habit or a life style, that starts to be the focus of the capitalist relations in all the spheres of the life and, the nature, or better, the nature concept, inside starts to be a mere product of this logic. At the same time it is placed idea to buy a life in harmony with the nature, what he is contradictory. The interest of the speculative agents, mainly those on ones to the real estate market, manifest and is materialized in the sales of ' ' areas? greens? found in the urban space, transforming the city, breaking up according to characteristic the areas favorable to the real estate incorporation of the territory. The woody quality of air, squares and parks become consumption objects. The nature becomes, due to rarity in some cities, a luxury article. Any object associated with a nature idea becomes synonymous of quality of life and makes possible the appropriation of values, through the increase of prices in land divisions, as the case of the Ecoville object of this study.
