The arborization is made thus it can help the environment as a whole, in the urban way, they have the important function to diminish the effect greenhouse, beyond preserving and improving the quality of the hdricos resources. We must remember the benefits of the trees: The reduction of the solar rays, forming a species of ' ' it keeps sol' ' that it produces shade in the sidewalk, with the reduction of the heat for the pedestrians also improving in the thermal comfort of the residences; The reduction of the effect greenhouse, that is the process that occurs when a part of the solar radiation reflected by the terrestrial surface is absorbed by determined gases gifts in the atmosphere, holding back heat and causing increase of the temperature; The reduction of the temperature and increase of the humidity of air, therefore provide to the surrounding renewal of the oxygen of air and hidratando the atmosphere by means of the processes of the photosyntheses and perspiration. Planted in the neighborhoods of buildings, the trees stabilize the internal temperature of these constructions, making possible lesser use of the air conditioners and, consequentemente, reducing the consumption of electric energy. The shelter and the abundant food for birds and other animals, therefore, the presence of trees in the urban areas provides shelter, food and even though they multiply in them; The biological diversity of arbreas species that can be preserved, beyond contributing for the improvement of the urbansticas conditions, and still can rescue cultural values and of memory of the city for the native inhabitants; The increase of water infiltration in the ground; It diminishes the force of the winds and assists in the reduction of the sonorous pollution: the trees made use in rows or bulks (together for the pantries), form true barriers that can contribute for the ambient improvement of the places where if they point out and generate benefits to the areas of entorno.

The occupation of the Village started as an invasion, at the beginning was about 130 people, occupying barracos constructed in the proper one I fill with earth with remaining portions of boxes wooden and plastics gotten in the garbage. In 1993 393 resident families in the area had been registered in cadastre, 149 of which surviving of the activity of catar garbage. In 1994 the number of resident families duplicated and passed to about 700. In 2005, the Structural one was one of the biggest invasions of the Federal District, with approximately 6,700 families, that is, of 28 the 30,000 people, with average income of up to two minimum wages. In 2006, the Government of the Federal District regulated the Complementary Law n 715/2006 that it created the Special Zone of Interesse Social (ZEIS), called Structural Village. The objective of the Law is the urbanization of the Structural Village (SEDUMA, 2007). Such information compose the scene to think the partner-ambient question, a time that: the inaquality is without a doubt one of expressions of the social inaquality that marked the history of our country. … Consequently Has strong correlation between poverty pointers and the occurrence of illnesses associates to the pollution for absence of water and sanitary exhaustion or for launching of solid rejeitos, liquid and gaseous emissions of industrial origin (ACSELRAD, 2004, p.1). The Structural Village constitutes, therefore a fertile field to argue the relation between socioeconmicos aspects and environment, that is, to develop a reflection on the ambient injustices that occur in the Federal District. 2. Historical aspects of the formation of Brasilia and the Structural Village the history of the Structural Village is confused with the history of the capital of the Republic. This fact evidences the necessity to retake the data historical of the formation of the city of Brasilia. Without the pretension to make minute a chronological picture of the construction of the city, we detach aspects of the past that, when being the urbanstica materialization of these ideas.
