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.
