Survival International is a human rights organization formed in 1969 that campaigns for the rights of indigenous tribal peoples and uncontacted peoples, seeking to help them to determine their own future. Their campaigns generally focus on tribal peoples’ fight to keep their ancestral lands, culture and their own way of living. (wikipedia.org)
