Okavango

The Okavango Delta is one of the world's 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.
