The rainforest is home to more species of plant and animals than any other habitat on the planet. But for humans, life there is not as easy as it looks. Life in the trees requires great skill, ingenuity and sheer bravery. The Matis of Brazil carve 4-meter-long blowpipes to hunt monkeys in near total silence. Deep in the Congo forests, Tete defies death by scaling a giant tree using nothing more than a liana vine, and he must then negotiate an angry swarm of bees, all to a collect honey for his family. Most memorable of all, in Brazil we join a unique monitoring flight in search of an un-contacted tribe.
