The thing that popped up in a different thread was about: if we all start doing really great and we start getting the big bucks for our awesome permaculture food, then doesn't that also mean that people wanting good food are gonna be stuck deciding between parting with the big bucks or with eating the chem food?
If you took the combines and tractors and harvesters out of the giant monocropping fields, there is no fuel energy savings. These vast amber waves of grain do not have the housing and infrastructure to support the substitute labor force. The labor would be driving in from miles around. Drive to work and home every day. How many people does a combine replace?
The future of agriculture will see a return to the land for certain. Housing and infrastructure will need to be built to make it possible.
if our new food system becomes a bunch of people trying to sell each other expensive things that aren't full of nutritionally dense calories, I have a feeling we'll all be kinda skinny.
my original "if everybody" statement was meant mostly as a joke, you know.
