the korowai tribe of papua new guinea are strong and good at climbing they have to be! they live in treehouses sometimes forty-five meters above the ground. the dense rainforest is hot and humid. there are insects and dangerous animals. treehouses protect the tribe from these dangers on the ground. they use material from the forest to build the houses. they cut off the top of a tree and build the floor first. it has to be strong because sometimes a family of twelve people live there. they use a ladder to get up and down. imagine the breathtaking views from one of these treehouses!
