Amazon - not the website

An uncontacted indigenous tribe has been discovered (see update below) in the Amazon rain forest of Brazil near the border with Peru. In some of the pictures, they don't look very happy about being found, and are threatening the plane with arrows and warpaint. Very sensible of them, I say.

According to the BBC article (quoting Survival International), there are about 100 uncontacted tribes in the world, more than half of which live in Brazil and Peru. I was intrigued - I didn't realize there are that many. I went to the Survival International website to find out where the rest are. It's down at the moment due to high volumes of traffic.
Lets just hope none of the planes accidentally drops a coke bottle where they can find it... Of course, nowadays it would probably be a plastic energy drink bottle.

Why does this story remind me of this?

Cheney: 100 Brazilian soldiers are joining our troops to help fight the war in Iraq.
Bush: That's GREAT! How much is a brazillion?

*UPDATE*: I found another website that indicates that officials have known about this tribe for at least 20 years, but only just published the photos to draw attention to the fact that the tribe is losing habitat due to illegal logging. They have already been pushed out of Peru and into Brazil...although I doubt it makes that much difference to them.
