For the coming century it'll have to be something different. Something sustainable. Our challenge is to get there from here - while avoiding or mitigating the potentially (or according to Jim Kunstler, http://kunstler.com/ certainly) disastrous consequences of the passing of worldwide peak oil output.
The question I ask myself is: what should a community, a place, a business, an individual, do TODAY to begin this transition. More specifically, what should Longleaf, Longleaf Development Company, Frank Starkey, do today to begin this transition?
reintroduce real agriculture
introduce on-site power generation; solar, wind, etc.
turn "waste" streams into resource streams: harvest rainwater and sewage, recycle and compost (man, do I wish I'd installed a good old windmill-powered well downtown, instead of a dumb submersible pump!)
encourage entrepreneurship in the Longleaf economy by providing places for businesses to incubate, and supporting the existing businesses
and somehow, there are educational opportunities in all this - with the preschool and elementary school in town, but also with middle, high, technical schools, and the community college and university.
Boy, I'm going to need some help!
