Modern Marvels: Environmental Tech (TV)

Modern Marvels: Environmental Tech takes us from the prairies of Saskatchewan to a Manhattan skyscraper as we explore the 21st Century's cutting-edge "green" technologies in action. The documentary looks at how human ingenuity takes on our most daunting environmental crises, from global warming and deforestation to resource scarcity and nuclear waste. Technological solutions include: carbon sequestration; converting carbon dioxide to algae-based biofuels; "green" building techniques and materials; using bioremediation to neutralize deadly uranium waste; creative recycling of industrial waste into useful materials; and reviving river ecosystems as a means of controlling catastrophic floods.
