A new uncontacted Amazon tribe in Brazil was discovered and recently confirmed by National Indian Foundation (FUNAI) of Brazil, a government body overseeing indigenous peoples.

Authorities have confirmed the existence of a group of approximately 200 uncontacted Indians in the Amazon.

An overflight carried out by the government's Indian Affairs Department, FUNAI, has revealed that these Indians are living in three clearings in the Javari Valley in the western Amazon, close to the border with Peru.

All over Brazil, indigenous peoples are living in differing degrees of isolation. Illegal miners, ranchers, loggers and other groups pose a risk to Indians' lives and well-being and destroy their natural resources.

Brazil's Amazon is home to more uncontacted tribes than anywhere in the world. There could be up to 70 isolated groups in this rainforest, according to FUNAI.

Their decision not to maintain contact with other tribes and outsiders is almost certainly a result of previous disastrous encounters and the ongoing invasion and destruction of their forest home.

For example, the uncontacted groups living in the state of Acre are probably survivors of the rubber boom, when many Indians were enslaved.
