I know “wood” instead of food was a typo but it brought a few things flashing back into memory.
A couple of things most people living today don’t quite grasp is the degree of hunting for food that occurred during the Great Depression.
Wildlife numbers were seriously depressed even into my childhood in the late sixties and seventies. It was a fairly rare sight to see a deer even in rural North Carolina, to the point that a set of deer tracks was a noteworthy thing, talked about down at the country store.
So, any wildlife that can be hunted for food will rapidly be hunted down and numbers will fall precipitously, taking decades to recover after the emergency period of want has passed.
Second, the “wood” part ... have you looked hard at old Depression era photographs from the south and east? Even in the cities and towns, forestation was gone. Ornamental trees along city streets, in churchyards and such was all there was. Just cut over as far as the eye could see.
Cheap fuel for heating and cooking, I guess, plus cash strapped landowners selling it all to keep from losing it to the bank or a tax sale.
It will be an interesting clash between the government environmental regulations and raw, panicky need, should a full on collapse ever arise. Major soil erosion, possible Dustbowl II in some dryer areas.
I can see some good in undermining regard for overweening environmental regulation and restriction in the long term. In the near term it’d be like living on the face of the moon after a few years.
