I first saw this last year on Wide Angle (a PBS series). It shows how carbon credits might be used to prevent the slash and burn of rainforests in Thailand while at the same time helping to rejeuvenate the economy of Banda Aceh (remember the tsunami?)

Excellent and very thought provoking. Would like to see someone succeed at this. Maybe the time is finally right.
