History of industrial agriculture:

<1940s: scarce but nourishing food
~1950-1990: abundant and nourishing food (depletion period)
~1990-present: abundant but depleted food

Next phase will have supply shocks of depleted food

The best move is to rotate back into nourishing foods by going local

going local is challenging in most places due to unfavorable climate. yes, we have enough technology to build a green house and create an ideal environment for growing anything you like but... that's unaffordable
