While permaculturists and Transition towns are still mostly practicing horizontal farming, a traditional concept that works well where there’s lots of land and not many people, what about cities? Here’s one video, showing what visionary architects are beginning to imagine. Just in time?

However . . . creating all these tall structures will take lots more nonrenewable resources. Will we recycle old buildings to build them? Will we use our ingenuity to creatively retrofit wherever possible instead? And to gear down, way way down, on personal energy use? Or will we just cross our fingers, count on technotopia, and meanwhile, continue to dredge and gouge and drain and mutilate Earth until she has no more to give.

Thanks to nextworld.tv. And see lots of other youtube videos on vertical farming as well.
