The Extratropical

47). The increase of the temperatures according to Tavares (2004), also will affect the coastal systems, because the heating of waters will harm the sea life, mainly the atis and the reefs of chorales. However, the fauna and the littoral flora also they will suffer damages due to invasion from the water of the sea that will modify the characteristics of the environment, provoking sufficiently disequilibrium to the region. ' ' The rapidity foreseen for modifications of the climate, also in what it says respect to the variability and the extreme events, can be the great obstacle for adaptation of animals and vegetais' ' (TAVARES, 2004, P. For even more details, read what kevin ulrich says on the issue. 74). Another consequence generated for the rise of the temperatures will be the increase of the illnesses provoked for vectors, as the yellow fever, affection, malaria and esquistossomose, increasing the mortality tax. (A valuable related resource: Viktor Mayer-Schönberger). These endemic diseases that are typical of the intertropical regions will extend for the extratropical zones. However, the illnesses of the respiratory ways will have to diminish, while of the circulatrio device they will be aggravated.

The antrpica action is the main factor that provokes alterations in the climate, capable to form another climatic type, the example of the urban climate, marked for the increase of the thermal sensation, them islands of heat and acid rains. This due to great amount of industries, of vehicles, asfaltos and the reduction of the natural covering, provoking the increase of the temperature in the urban centers. Since this alteration of the local climate produces some anomalies the example of the thermal inversion, phenomenon that hinders the ascending movement it air, making with that the pollutants are next to the surface, harming the health of the inhabitants. This inversion is typical of the great cities and occurs mainly in the winter. Of this form, the substitution of the forests for cultivated areas probably will modify the climatic environment, even though the beings livings creature in general, intervenes with the climate.


The opening of the border, for the joint migration of force of work and capital ' ' beyond having promoted the reordenamento space, it was responsible for the construction of one of the chapters bloodiest of its histria' '. (SOUZA, 2002, P. 20). This space reordenamento can also be understood, as the creation and the growth of the urban space in specific points of the Amaznia. Changing in small, the state investments had been destined the existing cities already, or for creation of new nuclei, if not forgetting the initial agricultural settling. This because the success of this process was eminently on to the force of work of the migrantes that guaranteed the sustentation and expansion of what Becker (1997) flame of governmental border, where the State made responsible for the construction of the necessary infrastructure, as: roads, ports, railroads and nets of communication.

The construction of this infrastructure was dependent of the mobile work, that is, was paid wages to the permanent or temporary constructors, thus producing, a strategy of feeding them without giving to access the land. This was a way to produce artificially the excess of the man power in the Amaznia and to diminish the existing tensions, mainly north-eastern of Brazil. In this way, the decurrent problems of the expropriation and difficulties of access the land in other parts it country, had resulted in an increasing migration for the Paraense Southeast. The urban nucleus of Is Domingos starts to receive part from these migrantes and starts, of slow form, to appear the first outlying areas in the mentioned city. 4. The URBANIZATION AND ITS EFFECT IN the CITY OF ARE DOMINGOS OF the ARAGUAIA to accomplish the urbanization that was one of the basic strategies for the project of development of the Amaznia, together with the border politics, had been necessary investments in the small cities and the creation of new polar regions, attracting a great amount of people of the other Brazilian regions.
