From the prairies of Saskatchewan to a Manhattan skyscraper we'll see the 21st Century's cutting-edge "green" technologies in action. New technologies such as carbon sequestration and bio-remediation take on our most daunting environmental crises, from global warming and deforestation to nuclear waste and resource scarcity. See how blue-green algae are converted into automotive bio-fuel and methane from decomposing garbage is turned into clean-burning natural gas. Finally, see how trees and other natural environments can be used as engineering materials to control flooding and rejuvenate dying rivers.
