大裂谷:美丽的非洲心脏

简介:

  【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.

简介:

北极地区总是带着神秘色彩,也是神话传说中的迷人胜境。然而,这里每年有九个月被冰雪覆盖,生存环境比世上其他地方更为严苛。这里乍似冷酷无情,原来却是不少物种的家园 ——北极熊、弓头鲸、一角鲸、厚嘴海鸦,还有人类皆居于此,北冰洋部分水域更是全球最丰饶的海洋生态系统之一。数千年来,因纽特人和前居者适应了北极地区,并在此落地生根。他们在冰原上寻找食物,互相交往,起居作息。为了生存,因纽特人还发展出一些特别的技能,他们透过观察冰雪反照在云层上的光,便能判断在远处有没有开阔的水域。这些传统智慧正好帮助前来研究的科学家。现时,北极地区已成为研究重点,科学家揭露了全球人类活动正如何影响这片遥远脆弱的地方。全球暖化对北极地区的影响比其他地方更为严重,北冰洋上的永久浮冰已缩减近百分之七十,如情况持续,终有一天北冰洋在夏季将完全无冰。世代生长在这片冰天雪地的动植物和居民能否适应这种变化?全天域电影《奇幻冰极》在探访这片奇妙异境之余,更会介绍冰对于北极地区和全球各地所发挥的重要作用。大家齐来与科学家和因纽特人一起,细察这个冰雪王国。
