Brazil uses radar to protect isolated tribes | World news The Brazilian government has said it will employ heat-seeking radar in a last-ditch attempt to save the country's remaining groups of isolated Indians. The body-heat sensors will be mounted on a Brazilian air force jet normally used to monitor rainforest destruction and will be used to locate an estimated 39 groups of isolated indigenous people, hidden deep in the Amazon rainforest. The authorities hope the system will help them to locate groups of isolated Indians to protect them from invaders such as loggers, goldminers and ranchers. Antenor Vaz, the coordinator for isolated tribes at Brazil's National Indian Foundation, said the system would allow authorities to locate tribes without disturbing their way of life. "We have been using planes more and more, not just to monitor [isolated tribes] but also to find new references," he said.
There are hundreds of indigenous tribes in the Amazon rainforest. The indigenous groups in all of South America have disappeared or been torn apart by the colonization process, disease, alcohol, forced labor and war. For long period of time the Amazon rainforest was a giant refugee for the indigenous population. This happened because the lack of a clear economic potential to be exploited by the colonizers.
