Alex Steffen writes at Worldchanging“ Where might we be on climate today if Carter had won in 1980? What would America look like if 1970s environmentalism hadn’t met such a quick and brutal end? What would sustainability itself look like — would we all be living in a world of arcologies, living machines, and whalesong? Would America be a green superpower? Or would we simply be Europe, living better on less? Or would we be living in a stagflationary sweater-vest hell? What do you think might be different if that election had gone differently, and what lessons might it have for us this year?”
