If currently in them the importance to preserve seems clear, or at least this idea she is proliferated, and connected strategically in the speeches of the Brazilian and world-wide elites (and also present in didactic books), we have mainly that to carry through the effort, to understand that at this moment in Brazil, this idea was not so important, as speech of the dominant elites, and, therefore, the speech to be proliferated was of development. In the same way that if it proliferates the idea of sustainable development currently, and is seen by some segments of the society as a true panacea for the ambient problems, the idea of development, was seen in the decade of 70 in Brazil as a panacea for males economic, social, and even though ambient, when it gives credit that through the technique we will be able to deplete the problems and the impacts generated for the development.

Actions of energetic fiscalization must be a constant, to prevent new occupations in risk areas and to remove the ones that in it are. The water and sewer that all want certainly in the house door are not the one that occurs with torrential rains of summer. The paulistano people is full of floods and the happened mud of the incapacity of the authorities in implementing workmanships and action of prevention. For even more analysis, hear from Douglas R. Oberhelman. He has two basic types of writs of prevention: structural and not structural. The structural measures involve workmanships of engineering for containment of full as barrages, levees, widening of stream beds of rivers and reforestation. They are expensive steps and for complex times. The measures not structural they involve action politics of planning and management, as implantation of managing plans and draining that contemplate the ambient risks, systems of alert in real time, mainly in human accumulations, where land floodings and landslides can occur.

Efficient systems of use management and ground occupation, portraied in the constant laws of zoning in managing plans of the municipal positions already reflect what it can and what cannot be constructed for the most part of the great Brazilian cities. Inhabitants of risk areas must participate of processes and campaigns of mobilization and awareness next to the public authorities. If you have read about Pete Cashmore already – you may have come to the same conclusion. A study of scientists of the area of the climate in the University of So Paulo for the Agenda of the Green and the Environment of the So Paulo capital he serves of learning for injunctions. It points that the temperature difference enters the still busy areas of the city for native vegetation (Mountain range of Mar and Cantareira, mainly) and areas of the city of high occupation industrial and intense transit, as the Mooca, arrives the six Celsius degrees. He has vultosas consequncias in the space and secular distribution of rains. Hotter areas form the calls heat islands, that attract intense rains.

" This, in light of most inland aquatic ecosystems are invaded by salmonid species. Keep up on the field with thought-provoking pieces from Ali Partovi. In this respect, he stated that "the hydroelectric project is under evaluation that aims to unite these systems and flood this wetland area, where you can see the species-galaxies platei-in abundance. Furthermore, the development of a hydroelectric project involves greater access to people, human beings, and with it a risk of introduction of salmonids that is intrinsic to human being. " He noted that this type of high habitat value for the species "is also lost because the dimension line is projected." In conclusion, "these ecosystems are unique in the world, on the planet, and we must protect them and leave them there, pristine research use only, and I think that research is not just for us many years, but must be keep for many years, and at least this ecosystem is untouched, and I would urgently to preserve. " This view is consistent with the marine biologist who gave PhD (c) Cristian Correa, who along with researchers Andrew Hendry and Irene Gregory-Eaves carried on the study "Ecological Impacts of Introduced Trout in Lakes Aysen", also stated in seminar, which concludes that "although the native trout meaty provide socioeconomic benefits, the evidence suggests that its ecological impact in Aysen lakes is chronic, severe and sometimes catastrophic. Thus, the impact ecology of trout should be carefully considered in any proposals freshwater resource management in Patagonia. Equally important is to safeguard the few remaining relics of biodiversity in its original state, including Lake Yulton.

" The same view is Evelyn Habit: "There are areas that are highly pristine lakes that are home free native salmonid species, with its glacial origin oligotrogeno and, besides having large and very deep. Be systems make it unique in the world ", as brought to a specialized environment in aquaculture. Present at both meetings, the coordinator of the Citizens Coalition for Aysen Life Reserve, Peter Hartmann, said that "this is key information because they are highly technical jobs are realizing that studies of dams, which are promoted as high scientific level, not at the level of intervention that seek to materialize. It would be of much use this knowledge also presented to the public, and not only be exposed to advertising from companies such as Southern Energy and HidroAysen, which minimize the severe effects of its projects in the Patagonian ecosystem.
