Never-before-seen high-definition footage of an uncontacted Amazonian tribe has surfaced in a recent interview between an American conservationist and podcaster Lex Fridman. Author Paul Rosolie has spent two decades working in the Amazon and says the moment was one of the most profound experiences he’s ever had. “In order for any of this to make sense, I had to show you this footage … This has not been shown ever before. This is a world first,” he told Fridman.
