A paradigm I would like to see shifted is our economic system's dependency on exponential, limitless growth. I think we're in for some rough times ahead and if I live to be 100 I might have to experience some really painful changes. Another thing I would like to see is the end to centralized energy. Rather than destroy the desert with solar plants (you should see them, oh my god) we should all have solar on every building. Rather than destroy the desert with windmills (sorry, that is not clean energy, I've seen it) we should have our own windmills in the back yard or on the roof. Also, rather than shit in our fresh water it would be nice to see composting toilets or gray water toilets instead. I don't know if any of that is paleo, except maybe the toilets. Paleo pooping. Maybe we could use green waste for TP.
By the way, last year there was this property near me for sale that had an off-the-grid homestead on it. Probably not totally self-sustaining as the high desert isn't going to allow for much of a garden, but it cost less than some cars and had a great pinyon pine tree and I wish it was mine.
