Earth: The Power of the Planet: Atmosphere

Documentary series. Dr. Iain Stewart reveals the crucial natural forces that have shaped the earth's development. A flight in a jet plane, a trip to the Andes and a trip to Shark Bay in Australia may seem expensive: but they're all necessary for Iain to discuss atmosphere. Without atmosphere, we couldn't live: we are, in his own words, but lobsters scuttling around in an ocean of air. Iain traces the history of the atmosphere: from the ozone layer's first creation to its current destruction.
