o add to this, there were issues when meat processing plants were closing down. Meat became difficult to find on store shelves for a while. Technically the meat was all there and could have been sent out to butchers but there was no infrastructure to support it and there weren’t enough people going to local butchers to buy it all.
Pigs grew to be too large to be turned into food and ended up being executed and disposed of rather than being used to feed people. The same thing happened to chickens. Cities rely heavily on the supply chain. It’s impossible for a city to exist without them since there’s no such thing as a self-sufficient city.
