At last, to have flexibility and adaptability to the new climatic requirements (physical earthquakes, volcanos and other elements), without congealing its structures. The things move quickly and the cities have that to have the resilience capacity. Great urban conglomerates had invaded and forcene the space of natural geography. In Rio De Janeiro and many great cities of the world, entire mounts had been busy for irregular and unsafe constructions. It has that if to redesign the urban growth of form to integrate it with natural geography, as to reactivate edges of rivers and to recoup ciliares bushes, so that the city if becomes arredia little and it does not receive a reply hostile from the natural environment.

To search to live in the break-even point is the great challenge of concentraers human beings who desire the support, dreams in being green cities. This that is important!
