Explanation:

The Indian communities in the Amazon rain forest are largely disrupted by the modern ways of life. Most of the tribes in the rain forest have never had contact with outside influences. The ones who have had contact only do so to trade and have little contact.

By setting up reservations, they way of life will change drastically. They will not be able to hunt as they have throughout their generations. They will not be able to live in their own handmade huts/homes. The reservation will bring the government into their lives and expose them to outsiders.

Being exposed to the outside world can cause physical damage to the tribes. Since they are not vaccinated, they can contract many diseases that are lethal and could wipe out whole tribes.
