According the human rights organisation Survival International, there are approximately 100 uncontacted tribes in the world today. More than half of these are believed to live in the Amazon rain forest in the Brazil-Peru region. Many of these tribes choose to have no contact with the outside world, sometimes by exhibiting hostility to outsiders, including neighbouring tribes.
