【内容简介】 东非大裂谷自红海至赞比西河口 ，连绵三千里，从太空都能看到。这里是多姿多彩的地方
，有喷发的火山、覆盖着森林的高山、美丽的峡谷、广袤的草原、巨大的平湖和河流，是鳄鱼 、河马、狮子 、大象、火烈鸟和非洲人的家园
。BBC采用最新的高清摄影技术，探讨了形式东非大裂谷的地质力量，展现世界上野生动物品种最多的地貌。 Visible from space, Africa's Great Rift Valley runs three thousand miles from the Red Sea to the mouth of the Zambezi
. It's a diverse terrain of erupting volcanoes, forest-clad mountains, spectacular valleys, rolling grasslands, huge lakes and mighty rivers
, and is home to crocodiles, hippos
, lions, elephants
, flocks of flamingos and a diversity of indigenous peoples
. Using state-of-the-art high definition filming techniques
, this series investigates the geological forces which shaped East Africa's Great Rift , and which make it one of the world's most wildlife-rich landscapes . Part 1 : Fire The valley is the product of deep-seated geological forces which have spewed out a line of cloud-wreathed volcanoes stretching from Ethiopia to Tanzania. Their peaks provide a refuge for East Africa's most extraordinary wildlife, including newly discovered and previously unfilmed species which have evolved surprising survival strategies to cope with their challenging mountain environment . Part 2
: Water The Great Rift Valley channels a huge diversity of waterways - rivers, lakes, waterfalls, caustic springs and coral seas - spanning from Egypt to Mozambique

. Some lake and ocean deeps harbour previously unseen life-forms, while caustic waters challenge life to the extreme
. But where volcanic minerals enrich the Great Rift's waterways, they provide the most spectacular concentrations of birds, mammals and fish in all Africa . Part 3: Grass The Great Rift Valley provides the stage for an epic battle between trees and grass - its course influenced by volcanic eruptions
, landscape and rainfall. On its outcome rests the fate of Africa's great game herds. In the Rift's savannas
, grazers and their predators struggle to outwit each other, forcing one group of primates to develop a social system that paved the way for the evolution of mankind.
