It#39s a diverse terrain of eruting volcanoes, forest-clad mountains, sectacular valleys, rolling grasslands, huge lakes and mighty rivers, and is home to crocodiles, hios, lions, elehants, flocks of flamingos and a diversity of indigenous eoles.br\ Using state-of-the-art high definition filming techniques, this series investigates the geological forces which shaed East Africa#39s Great Rift, and which make it one of the world#39s most wildlife-rich landscaes.br\ Part 1: Firebr\ The valley is the roduct of dee-seated geological forces which have sewed out a line of cloud-wreathed volcanoes stretching from Ethioia to Tanzania. Their eaks rovide a refuge for East Africa#39s most extraordinary wildlife, including newly discovered and reviously unfilmed secies which have evolved surrising survival strategies to coe with their challenging mountain environment.br\ Part 2: Waterbr\ The Great Rift Valley channels a huge diversity of waterways - rivers, lakes, waterfalls, caustic srings and coral seas - sanning from Egyt to Mozambique. Some lake and ocean dees harbour reviously unseen life-forms, while caustic waters challenge life to the extreme. But where volcanic minerals enrich the Great Rift#39s waterways, they rovide the most sectacular concentrations of birds, mammals and fish in all Africa.br\ Part 3: Grassbr\ The Great Rift Valley rovides the stage for an eic battle between trees and grass - its course influenced by volcanic erutions, landscae and rainfall. On its outcome rests the fate of Africa#39s great game herds. In the Rift#39s savannas, grazers and their redators struggle to outwit each other, forcing one grou of rimates to develo a social system that aved the way for the evolution of mankind.
