Host Jeff Young looks at the next decade of our planet. Jared Diamond, author of "Collapse," says our "present consumption rates just can't be sustained." But urban farmer Will Allen suggests that mounting food demands can be met by growing food everywhere ? in vacant buildings, on rooftops, asphalt, and on concrete. And Camille Parmesan, biology professor at University of Texas-Austin, suggests that the survival of wildlife may depend on our willingness to transport creatures out of the path of climate disruption.
