How the Earth Changed History
This visually stunning five-part series from the BBC and National Geographic reveals how geology, geography and climate have had a far more powerful influence on human civilization than has previously been acknowledged, through the perspective of a new science, geo-determinism. Travelling around the globe, geologist Iain Stewart discovers how the world’s powerful natural forces have influenced every aspect of our history, from art to industry, religion to war, world domination to collapse.

Deep Earth
In this five-part series, geologist Iain Stewart travels into the Earth's crust to understand Mother Nature's forces. We begin our journey a thousand feet below the surface in a geological wonder: the Naica crystal cave in Mexico. In Israel's Negev Desert, we'll uncover man's earliest source of copper, which changed our relationship with the planet forever. (1 of 5)
Water
Our struggle to control our planet's forces has been behind the rise and fall of some of our greatest civilizations. In Africa, we'll discover how early communities found water underground in the desert, and how this guided their food supply and economy. (4 of 5)
Wind
Iain learns about the impact of the Himalayas on wind patterns, then jets over to Australia's Red Center, where a giant swirl of wind relentlessly stripped the land of its fertility, forcing Aboriginal people to survive as hunter-gatherers while civilizations elsewhere developed agriculture. (2 of 5)
Fire
From the earliest hearth fires that kept prehistoric humans warm, to the fuel that thrusts rockets into space, our ability to master fire has driven human history. In this episode, Professor Stewart walks through the heart of a staged fire (approaching 3,000 degrees F) wearing a state-of-the-art fireproof suit and special breathing equipment. (3 of 5)
Human Planet
Travelling to the Canadian Rockies, Iain peels back the historic record locked in ancient ice to see how man's earliest agriculture may have sparked global warming. (5 of 5)
