Josh Coulter Posted over 1 year ago Sunken Cities Noah - thanks for the response! Your questions bring me to a whole new set of questions. If we were to build an above-ground city, how could we think about the layout and design of a city that would be fundamentally different, with the focus on eliminating as many emissions as possible and keeping the city as green as possible, in order to have a negligible impact on global warming? Some of my original thoughts still come to mind, including reliance on mass transit which is smartly built to provide service to as many residents as possible, and eliminate roads to keep cars out of the city. Also - how would the city be kept green? Larger, high-rise residential buildings that have gardens on the tops of the buildings, or, somehow, hanging gardens surrounding nearly the entire building? What other thoughts might you (and others) have in regard to building green (and that's more than just sustainable-green, but definitely sustainable) cities?
