True that !
A food shortage makes for desperate people,
especially in the cities where the population is compressed and is more dependent on a broken supply chain, and,
where there is no room for a home garden.
This results in scavenging for self and family survival and a desperate population,
and then the rules of society and civilization may no longer apply.
My grandfather (born 1915) often spoke of the family eating Robins during the depression... I wonder if the meat texture is similar to quail? Hmmm.

I used to hang out with a guy that did the mountain man thing, and the annual rendezvous that they organized. They were pretty hard-core. The only serious anachronism that they allowed was Coleman canoes. He used to brag about the woodpecker stew that he made.
Even if you had a home garden, some lazy SOB will steal from it after you have done the hard work.
