This is not a commonly explored issue.
The story is also the current homepage of Survival International. From the site: ‘We did the overflight to show their houses, to show they are there, to show they exist,’ said uncontacted tribes expert José Carlos dos Reis Meirelles Júnior. Meirelles works for FUNAI, the Brazilian government’s Indian affairs department…
Meirelles says that the group’s numbers are increasing. But other uncontacted groups in the region, whose homes have been photographed from the air, are in severe danger from illegal logging in Peru. Logging is driving uncontacted tribes over the border and could lead to conflict with the estimated five hundred uncontacted Indians already living on the Brazilian side.
‘What is happening in this region [of Peru] is a monumental crime against the natural world, the tribes, the fauna and is further testimony to the complete irrationality with which we, the ‘civilised’ ones, treat the world,’ said Meirelles.
There are more than one hundred uncontacted tribes worldwide, with more than half living in either Brazil or Peru. All are in grave danger of being forced off their land, killed and decimated by new diseases.”
