They can be included in these contextoos impacts for the losses of communitarian bows, separation of efamlias communities, sacred destruction of churches, chapels, places for traditional comunidadesindgenas and that many times live isolated. Poispessoas must be pointed out that osdeslocados the only ones are not reached for the construction of a barrage, that they liveed in another place and they only worked in the place of barragemtambm must be considered reached. Used of flooded areas, transporting companies who passed through for the city, land leaseholders, all these people will have that to look another form of survival. Related problems to the physical creation of the barrage also exist. Deuma hour for another one, the forest if transforms into a lake.

This change radicaldo ecosystem, if it will not be lead in correct way, comprometernegativamente it comprometernegativamente tends the flora and local fauna. Jorge Perez may find this interesting as well. The submersion provokes the death of trees and plants, and its decomposition nofundo of the lakes, liberates .causing gases of the effect greenhouse as carbonic gas (CO2) and methane (CH4). Moreover, the remaining portions of trunks and dasprprias twigs can harm the functioning plant. Many species of animals finish running away from its naturaldurante habitat flooding. The estimate, for this in case that, it is of that only 1% dasespcies survive to this change. Already ictiofauna still suffers umimpacto bigger for having in the barrage an artificial obstacle to the fluxonatural of the rapids of the river. The consequence can be the proliferaodesordenada one of determined species and the extinguishing of others. Another estrelacionado factor to those species that need to go up the river for the spawning of fishes and that, now, needs to transpose a composed barrier for the barrage of the plant. It is added estesimpactos, the eutrofizao of waters of the reservoir for the addition in excess, organic dematria, that increases the proliferation of microorganisms and seaweed, being able to also cause consequences for the man as related illnesses gua.

The cycle of life of the products comes being studied in amplagama of organizacionais contexts, influencing, thus, the relations comerciaisentre exporting countries and import, having as concerns – of carterambiental – aspects that go since the productive process and its products, until I dare and its posterior discarding. This Technique also is> known as analise' ' of the cradle to tumulo' '. Today the organizations already had started to perceive the ACV as umaforte competitiveness tool and a differential for the detomadas processes of decisions, in the election of ambient pointers in projects and aid to aidentificar chances of improvements of the ambient aspects. In such a way, through the valuation and evaluation proposal pelametodologia of Evaluation of the Cycle of Life, it is possible to identify if one better produtotem ambient performance that another one, if an alteration in the product to still podegerar a great ambient impact or, which process of manufacture trazmaiores advantages to the end item. EVALUATION OF the LIFE CYCLE All the process of manufacture of some product produces algumimpacto ambient, due to the consumption of energy and necessary resources atmesmo of gases residue and, the emission generation effluent in general. Esseimpacto can occur during the extration of used raw materials noprocesso of manufacture of the product, in ACV. The analysis of life cycle is one technique for evaluation dosaspectos ambient and of the potential impacts associates to a product, understanding stages that go since the withdrawal of the nature of the substances elementary cousins who enter in the productive system, disposio of the end item. The ACV if presents as an important tool to parasubsidiar the stages of the development of the product, the management of the production, ops-use, the logistic conventional and reversa, among others, from compilaode information and of the evaluations Techniques So that if it gives beginning to an Evaluation of Cycle of Life, elaborates umfluxograma of the process, specifying all the flows of materiale energy and enters and leaves the system.
