In case you haven't seen it, this is footage that the BBC shot of one of the last uncontacted tribes in the world, shot from a kilometer above the Amazonian jungle and released in February. Kind of amazing video.
Brazilian government researcher Jose Carlos Meirelles fears the tribes could be harmed by illegal logging on the Peruvian side of the border and hopes the footage will awaken a desire to protect them, stating in the video that "one image of them has more impact than a thousand reports."
