Yes Giancarlo, I also thought it was the same tribe Ray had visited. I didn't really recognize its name, although it did sound familiar too, but the village and its setting looked the same and their way of cooking manioc semolina on a cast iron tray (a split second sequence).
Yes very sad, in this program particularly it felt like a culture, a people on its last legs.
They had lost the vast region of forest where they used to lead their previous nomadic life. It seemed that they had been cornered by events beyond their control and then thought of a damage limitation solution:
living nearby the other tribe (forgot its exact name, the village that looked like where Ray Mears had first landed) which was a tribe already with one foot in our modern world which could provide them with medications and some medical care. It looked like this was a reasoned, deliberate decision.
Like one of you has said, the other tribe exploits them. It is all quite sad.
I have seen films and pictures and heard direct accounts from anthropologists etc on forest tribes in the Amazon some, say, 30 years ago. The picture was so different. These people looked quite different in appearence too: sharp traditional hair cuts, wearing nothing but something round their waist or hips and maybe around their legs right below the knee, etc Their general appearance was clean-cut, sharp, everyone in the village wore the same things: it looked distinctive, it had unity in appearance: never overall shabby and sad and full of bits and bobs the way these people sort of look now.
Well, long story...logging seem to be one of the main threat and cause of the decline of these tribes and their distinctive cultures.
