When tribes that have never been contacted by the outside world first encounter outsiders such as loggers, it is likely half of them will die of diseases, as they have never developed immunities to illnesses that are common in the outside world.

Some tribes are nomadic and may move away from areas of deforestation without encountering outsiders. These tribes are pushed further and further as deforestation spreads.

Other tribes are assimilated (those who do not die shortly after first contact). They take on jobs as loggers themselves or are moved into villages.
