As I said below:

Cozy small time agriculture in the west is a small part of your general food supply. The rest is in places you do not want to live and is called monoculture. A huge part of your food supply is not produced "in the countryside" in either Denmark or most of the West.

It all starts with oil and energy. Nothing else matters as much. So getting off oil and producing energy in other ways is at the forefront of our struggle as a species and if you deny this progress because it hinders the view from your detached house porch I get the impression you have not really realized the situation we are in.
