BBC最新紀錄片，講述地球的氣力如何改變了人類的汗青。2010年1月19日首播，共播出了5集：'Water'，'Deep Earth', 'Wind', 'Fire'，'Human Planet'。節目中，Iain Stewart 教授帶領觀眾探究幾個世紀以來，地質學、地理學和氣候是如何影響人類生活的。　　我們的星球擁有驚人的氣力，但卻很少在教科書中被提起。這個系列節目第一次通過電視展現地球的神奇氣力對人類成長的影響。節目將汗青故事的講述和炫目的攝影鏡頭緊密結合，給我們顯現一幅原汁原味的人類汗青圖景。　　Iain Stewart tells the epic story of how the planet has shaped our history. With　　spectacular images, surprising stories and a compelling narrative, the series discovers the central role played in human history by four different planetary forces.　　Episode 1: Water　　Professor Iain Stewart continues his epic exploration of how the planet has shaped human history. This time he explores our complex relationship with water. Visiting spectacular locations in Iceland, the Middle East and India, Iain shows how control over water has been central to human existence. He takes a precarious flight in a motorised paraglider to experience the cycle of freshwater that we depend on, discovers how villagers in the foothills of the Himalayas have built a living bridge to cope with the monsoon, and visits Egypt to reveal the secret of the pharaohs' success. Throughout history, success has depended on our ability to adapt to and control constantly shifting sources of water.　　Episode 2: Deep Earth　　Iain Stewart tells the epic story of how the planet has shaped our history. With spectacular images, surprising stories and a compelling narrative, the series discovers the central role played in human history by four different planetary forces. In this first episode, Iain explores the relationship between the deep Earth and the development of human civilisation. He visits an extraordinary crystal cave in Mexico, drops down a hole in the Iranian desert and crawls through seven-thousand-year-old tunnels in Israel. His exploration reveals that throughout history, our ancestors were strangely drawn to fault lines, areas which connect the surface with the deep interior of the planet. These fault lines gave access to important resources, but also brought with them great danger.　　Episode 3: Wind　　Professor Iain Stewart continues his epic exploration of how the planet has shaped human history. Iain sets sail on one of the fastest racing boats ever built to explore the story of our turbulent relationship with the wind. Travelling to iconic locations including the Sahara desert, the coast of West Africa and the South Pacific, Iain discovers how people have exploited the power of the wind for thousands of years. The wind is a force which at first sight appears chaotic. But the patterns that lie within the atmosphere have shaped the destiny of continents, and lie at the heart of some of the greatest turning points in human history.　　Episode 4: Fire　　Professor Iain Stewart continues his epic exploration of how the planet has shaped human history. Iain explores man's relationship with fire. He begins by embarking on an extraordinary encounter with this terrifying force of nature - a walk right through the heart of a raging fire. Fire has long been our main source of energy and Iain shows how this meant that the planet played a crucial role in Britain's industrial revolution, whilst holding China's development back. Along the way he dives in a mysterious lake in Oregon, climbs a glacier of salt, crawls through an extraordinary cave in Iran and takes a therapeutic bath in crude oil.　　Episode 5: Human Planet　　Series in which Professor Iain Stewart looks at how four geological forces have shaped human history. He explores the most recently established force, humans. It's easy to think of the human impact on the planet as a negative one, but as Iain discovers, this isn't always the case. It is clear that humans have unprecedented control over many of the planet's geological cycles the question is, how will the human race use this power?
