The Settlers got to the Amazon Rainforest in the 1960's when the Brazilian Government began encouraging poor people to move in the rainforest. When they migrate they clear-cut the trees off the land to make farm fields. This isn't sustainable because the soil so too thin and constant rain washes the soils nutrients. Then when the land isn't good enough anymore the settlers find another piece of land ,and do the same process all over again. That's why the settlers have conflict with the Native Amazonians , Rubber Tappers, and the Environmentalists. What the settlers want is to clear the forest land for subsistance farming , so that they can grow or feed their family. All they want is land and food for their family.
