This aerial footage showing one of the world’s last uncontacted tribes living in the Amazon rainforest of Brazil was filmed by the BBC for their new series “Human Planet” and released via uncontactedtribes.org on February 4, 2011.

“Without proof they exist, the outside world won’t support them,” says José Carlos Morelos, whose job it is to monitor the endangered tribe’s land and protect it from invaders. “One image of them has more impact than a thousand reports.”
