Isolated tribe spotted in Brazil

I was very happy to find out that there are uncontacted indigenous tribes still in the world. Recently a previously uncharted village has been photographed from the air. I am also pleased to read that the Brazilian government is aware of several such tribes along the Brazil-Peru border and plans to protect them from the outside world. It is VERY important to do so! We have inadvertently destroyed many indigenous micro-cultures by allowing well meaning ethnographers, to start, then missionaries and later indifferent government agents, tourists, and unscrupulous traders to slowly erode those cultures, luring them into our "civilized" world where they without fail end up at the peripheries of society, broken and exploited.
