Survival International : Survival is the only international organisation supporting tribal peoples worldwide. Today, Survival has supporters in 82 countries. It works for tribal peoples' rights in three complementary ways: education, advocacy and campaigns. We also offer tribal people themselves a platform to address the world. We work closely with local indigenous organisations, and focus on tribal peoples who have the most to lose, usually those most recently in contact with the outside world.
