Witness wonders created by the force that makes our planet unique — life itself. In the Amazon Rainforest, two 9-year old boys must prepare themselves for a terrifying rite of passage involving the insect with the most painful sting on Earth: the bullet ant. In Borneo, a father must provide for his family by climbing to the roof of a vast cave to collect birds’ nests. And, in Bangladesh’s Sundarbans, the largest mangrove forest in the world, a father and son must brave killer bees and man-eating tigers to find honey.
