Vertical farming will be big. 60 story hydroponic tanks with solar mirrors for sides and recyled water systems based on our interplanetary exploration craft. Eventually the LeGrange points will be populated by captured comets and asteroids and such, fueled from the Moon, and full of bioengineered plants/trees and such. Incidentally it will be inside these giant free-fall constructs that the flying humans will come into their own
We will have manna from heaven as drone craft full of fresh produce land 24-7 wherever it seems appropriate. The downside will be the pollution. We have traces of plastic microfibres in our DNA right now - that is very scary shit. Also we will eventually be buggy with nanobots pumped out by government agencies, big business, the religious freaks and the entertainment industry. Neural firing inside the head triggered by nanobots working according to an outside script will lead to some pretty wild new paradigms.
Enough for now - must go drink coffee - and I desire a smoke ...
