How the Earth Changed History – Water World

Today on Discovery Enterprise we are presenting a brand new series entitled “How the Earth Changed History” hosted by Iain Stewart with the first episode entitled “Water World”.

National Geographic Channel first aired “How the Earth Changed History: Water World” on Sunday June 20, 2010 at 7:00 p.m. ET. This was the first of five episodes debuting between June 20 – 22, 2010. National Geographic Channel is taking viewers from deep beneath the crust of the earth to the skies to look back at how Planet Earth has helped shaped human history, and how history has shaped the earth.

How the Earth Changed History: Water World is the first of five episodes of the series. The other episodes include Beneath the Crust, The Skies Above, the Gift of Fire and The Human Era.

Water is the planet’s essential lifeblood. Water is constantly transforming itself, shifting between guises and from place to place. Of all our planet’s forces, perhaps none has greater power over us. Our struggle to control it has been behind the rise and fall of some of our greatest civilizations throughout history.

In Africa the show rediscovers how early communities found water underground in the desert, and how this guided their food supply and economy. Viewers joined Prof. Stewart on a trek to Cherrapunji, India, where average annual rainfall approaches 40 feet, to see how an overabundance of water has created the need for an engineering partnership between man and nature in the form of bridges grown from the roots of trees. These beautiful and ancient constructions take hundreds of years to grow and only get stronger as they grow older.

In Iceland, the viewer follows the never-ending cycle of water as it rises from the oceans to clouds from which it rains down and forms rivers, then is bound up as ice or stored below the Earth’s surface, only to return to the oceans and repeat the cycle again.
