@robcornelius My father is a farmer, I see how intensive farming created higher yield over the years and how approaches to bring in more people failed on multiple accounts. When its a matter of starving vs working the land, it will be difference. But than it will be different for nearly all other "moving parts" too. Think of the people of London, Berlin, Paris or Warsaw having to move to the country side and live there. there is not even enough infrastructure in housing of energy provision...
