Global: Indigenous people the missing delegate at Cancun

As nearly 200 delegates gather at the Conference of the Parties in Cancun, Mexico, writer Dennis Martinez points out that Indigenous peoples and their advocates have no official seat among nations, and yet have experienced the worst impacts of climate change. To solve the problem, delegates of the wealthy nations have a climate-mitigation plan of choice - carbon offsets embodied in a program called Reduced Emissions from Deforestation and forest Degradation (REDD). But for healthy and stable ecosystems, Martinez finds that it fails to measure up to an overlooked method: continued indigenous stewardship.
