Scientists and inventors are on the front lines of the battle against global warming and pollution, rapidly developing remarkable--and sometimes bizarre--technologies to help reverse the damaging trends. ENVIRONMENTAL TECH explores the science behind Earth-saving advancements such as pollution-eating algae and carbon sequestration.
Description by New Video Group:
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 bioremediation 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 biofuel and methane from decomposing garbage is turned into clean-burning natural gas. Finally, we'll see how trees and other natural environments can be used as engineering materials to control flooding and rejuvenate dying rivers.
