“Why can’t we plant fallow fields?”
The yields won’t be economically feasible without fertilizer in many areas. In many places it makes an enormous difference.
Oh yes, fertilizer, I nearly forgot. We have to use fertilizer on our lawns to keep them green, not our food-producing fields. You have to keep the neighborhood association happy.
Buy a book on farming. Till up your back yard. Go to the barn and get manure. Wait for weeds to grow and spray them with weed killer. Till it up again. Plant, hoe often. When the food matures. Can it, freeze it, and otherwise store it. Taa Daa! Food you got from fallow ground. See any problems here?

The money quote:
We believe we are at the onset of a global famine of historic proportions. In a staggering defiance of logic, many US politicians are still attacking the lifeblood of our own energy production infrastructure, looking to score political points against “the other team,” blaming price-taking producers of global commodities for gouging, threatening producers of energy with windfall profits taxes, resisting calls to remove bureaucratic hurdles to new production, and refusing to open an introductory physics textbook to help guide them through the suite of policy choices that require true leadership to get right. They remain stuck in an endless loop of platitudes, blamestorming, corruption, and ignorance.
Prepare accordingly.
