No doubt early people fought over the hunting/fishing/gathering grounds - a very big deal..............
I have wondered about the eating habits of hunter/gatherers. Seems like it wouldn't be much fun, but means you eat things by season, or capture. Kill a deer and that's what you eat for a week..berries are ripe, ditto. Bugs on the other hand have longer available seasons....................Bad weather and scarcity + competition makes one wonder if there were wars over berry patches. Maybe this is why our ancient ancestors might be considered old people at 40ish.
I think only in an overfed, obese, modern society do you see vegetarians and vegans. (enough to be a thing) If we are ever forced to go back to growing all of our own food, this will disappear.
Where I grew up, we had pork/beef season - November to April (after that it is hard to keep meats frozen in big volume).
Goose season - October to April.
Chicken season - August/September until no more young roosters to slaughter (occasional chicken through the year).
Fresh egg season - March/April to November.
Fresh milk season - March/April to October.
Roughly April to August was very little fresh meat (salted/dry/canned meats; fresh caught or store bought canned/salted fish).
So it was mostly vegetarian diet April to August/September.
Though meats, bread, and potatoes were considered the "real food".
Looking back, it is shame so many good vegetable options were ignored or considered animal feed.
Just a shame for that.
