World's Last Uncontacted Tribes

Survival International has released pictures of world's last uncontacted tribes living in Brazil, near the Peruvian border. Invasion of loggers from Peru threaten the survival of this tribe as loggers penetrate in protected areas and destroy the tribe's environment. Contact with exterior world could end up destroying the tribe as history has shown us.
A petition can be signed at Survival's website to ask Peru's President to help protect uncontacted tribes.
