In Prepper circles, when we speak of when the SHTF or TEOTWAWKI, those you speak of are called "Zombies".
I don't know about all that zombie talk. I guess in the cities they can't live a subsistence lifestyle like out here.
WE have all kinds of local dependent on govt checks, but everybody lives off what the land & river provides too. So I figure those people be eating salmon 24/7 if it gets bad. Heck the Indians do and don't even realize there's anything wrong with it, ha ha.
Ya know out here people don't play the end of the world game, they have lived that lifestyle for decades out of necessity. Our nearest Sams is 500 miles away. Cost prohibits flying everything in, so people have always had big gardens and lived off moose & caribou & salmon. Most everybody has 3-4 years of basic supplies and the ability to make do with what is out here. Nothing wrong with rendering bear fat down, no joke.
