RIO DE JANEIRO, Brazil — One of Brazil's last uncontacted Indian tribes has been spotted in the far western Amazon jungle near the Peruvian border, the National Indian Foundation said Thursday. There are more than 100 uncontacted tribes worldwide, most of them in Brazil and Peru, the group said in a statement. "These pictures are further evidence that uncontacted tribes really do exist," Survival director Stephen Corry said. "The world needs to wake up to this, and ensure that their territory is protected in accordance with international law. Otherwise, they will soon be made extinct." Now, some ask "But, did they want to be found?" I ask, "were they lost?"
