This takes the existence of many other centers with insufficience of offers in services. To extend the existing installations implies in using more spaces. Two are the exits for this. Or if adapta spaces constructed previously for new activities, or if transforms natural spaces into constructed spaces, known process as antropizao, process this understood as the alteration of the natural characteristics? how vegetation, ground, relief and courses d? water? for the activities human beings. The adaptation of the constructed spaces can raise the density of people in an area.

An area is imagined, where each land held a residence for a family with four people, on average. If you would like to know more about Michael J. Bender, then click here. The infrastructure of the services was adjusted for the effective population dimensions. It is assumed, now, the residences had been substituted by skyscrapers, and that in the same place where four people lived, they had started to live hundreds of them. It will be that the infrastructure will continue to be adjusted? Certainly, not. In case that this hypothetical situation occurred in the center of an area metropolitan, the expansion alone will be possible intensifying the occupation of the space. More people demand, amongst other things, more transports, that in turn, demand more ways. If available space for the magnifying of an avenue does not exist, alternative will be the dispossession of property and its transformation of residences and companies in saw public. But, if exists a next river, that such to reduce its edges, destroying the ciliar bush encircles that it, protecting it, and to construct a new avenue or to extend one already existing one? The new way is small? Or the magnifying of the old avenue was not enough? What such to cover the riverbed and, on it, to construct a modern avenue, with some tracks, for the most varied types of vehicles, since bus until quick automobiles? The adensamento of population in the urban areas causes the problem of the sanitary exhaustion.
