In these new ways, stimulated for the development idea, the region that shelters the biggest biodiversity of the planet, in the same molds confided for the exploration as if they had extracted raw materials of Atlantic Mata per 500 years: wood, followed of cattle extensive, occurred for agricultural production in scale industrial. In the productive succession, the ecological exhaustion of environments is clear where if these practical productive are developed, followed of the migration of the activity for new lands or the substitution for intensive systems of production with raised load of insumos, accessible for a reduced number of agro-industrial complexes, highly subsidized for State (Hunter, 2001) 2.

Beyond obvious factors economic politicians and who certainly subjazem to these separatistas speeches, we can be led to think that it also has inadequao of this migrante population to an Amazonian cultural identity, since great part DES.
