剧情简介:<p>　　【内容简介】<br/>　　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。<br/>　　Visible from space, Africa&#39;s Great Rift Valley runs three thousand miles from the Red Sea to the mouth of the Zambezi. It&#39;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.<br/>　　Using state-of-the-art high definition filming techniques, this series investigates the geological forces which shaped East Africa&#39;s Great Rift, and which make it one of the world&#39;s most wildlife-rich landscapes.<br/>　　Part 1: Fire<br/>　　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&#39;s most extraordinary wildlife, including newly discovered and previously unfilmed species which have evolved surprising survival strategies to cope with their challenging mountain environment.<br/>　　Part 2: Water<br/>　　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&#39;s waterways, they provide the most spectacular concentrations of birds, mammals and fish in all Africa.<br/>　　Part 3: Grass<br/>　　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&#39;s great game herds. In the Rift&#39;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.</p>
