We are also watching the odd episode of "Living with the Kombai": on Discovery World, which we are finding really fascinating.
I was wondering exactly the same thing r-marie:
In the next episode the tribe face starvation, but why, when they are surrounded by such lush greenery?
I found the following on the Discovery website (Kombai facts):
The Kombai are hunter-gatherers, moving from place to place during long treks in search of food. They eat cassowary birds, riflebirds, wild pigs, grasshoppers, tree kangaroos and snakes. However, their main protein comes from the larvae of the Capricorn beetle, also coined the 'sago grub'.
They also eat biscuit-like concoctions called sago, which are made from the pulp of the sago tree. The pulp is turned into flour and then baked or steamed. It is supplemented with green bananas, cucumbers, mushrooms, fruits and berries. Palm leaves and ferns make up their diet as well. The Kombai cook with hot stones.
They do eat plants, but looks like they rely on animal (insect) protein as their main source of food?
I haven't watched an episode relating to their diet.
