Great Rift: Africa's Wild Heart

The Great Rift Valley is the product of intense geological forces which have spewed out a line of cloud-wreathed volcanoes stretching from Ethiopia to Tanzania. As this compelling nature documentary reveals, its peaks provide a refuge for East Africa's most extraordinary wildlife, including newly discovered and never before filmed species which have evolved surprising strategies to survive.

The Great Rift Valley channels a huge diversity of waterways: rivers, lakes, waterfalls, caustic springs and coral seas, spanning from Egypt to Mozambique. As this engrossing documentary shows, some lakes and oceans harbor previously unseen life-forms. But where volcanic minerals enrich these waterways, they provide the most spectacular concentrations of birds, mammals and fish in all Africa.

The Great Rift Valley provides the stage for an epic battle between trees and grass, influenced by volcanic eruptions, landscape, and rainfall. Its outcome, as this stunning nature documentary reveals, decides the fate of Africa's great game herds. Grazers and predators try to outwit each other, forcing one group of primates to develop a social system that paved the way for mankind’s evolution.
