Earth's Greatest Spectacles

New England is the stage for the most incredible colour change on earth, when the vivid greens of summer give way to the golds and reds of autumn. This film reveals how this vibrant fiesta is created by the battles between the trees and the forests inhabitants. Moose, chipmunks, rattlesnakes and a bizarre mixture of caterpillars all play a crucial role, but surprisingly the forest itself was made so colourful thanks to a combination of hard work by beavers, ants and humans.

The Okavango Delta is one of the worlds largest inland deltas - and supports a variety of life as rich as any you will see in Africa. Yet this lush wetland of islands and lagoons lies in the middle of the vast, featureless Kalahari Desert. This is the story of how it happens. Following groups of wildlife, including hippos, baboons, catfish, kingfishers, leopards, warthogs and elephants, the film reveals how the yearly flood transforms the landscape and impacts their lives. But more surprisingly, it reveals how, with the help of termites and hippos, the flood actually creates this extraordinary delta in the first place.
