Your comment uses so much loaded language that I'm not actually sure what you're arguing against or for. > actual green communities that don't require massive cement structures everywhere I interpret this as meaning more single-family homes rather than apartments and condos. That would mean urban sprawl which is anything but green. The lower the population density, the less effective mass transit becomes, and more people are driving. Most jobs can't be done from home. > self-sustaining communities I interpret this to mean not needing external resources, but this would mean your food choices are limited based on the whims of the local climate. Live up north? Then you're not getting any mangoes or other tropical fruits.
