RIO DE JANEIRO, Brazil (AP) — The Brazilian government will begin using a plane equipped with body-heat sensors to locate — and protect — uncontacted Indian tribes in the Amazon, officials said Tuesday.
Locating the tribes will help the National Indian Foundation create reserves where loggers or farmers are barred, Antenor Vaz, who heads the work on isolated tribes for the agency, known as Funai.
I'm glad to see that the Brazillian gov. is ostensibly looking out for these lost tribes(of course it would be nicer if the gov didn't have to step in to stop loggers and farmers from encroaching on these lost tribes' native lands), but there is always the chance of bringing a new disease into the isolated communities, and that the searchers' presence might be misinterperated as has happened
before.
Sounds like some interesting heat signature technology. At first I thought it might be hard to separate animals from humans but, I suppose it's not that hard to distinguish an animal's heat signature from a human's if there's a large village of humans.
