>>2856323The big problem is having enough food and how to store and make it last through winter if you live in that environment.
Having some goats or sheep and chickens will provide you with milk and egg, but the animals will also require food so it's hard having many, which also limits the food they can produce.
Hunting, trapping, fishing and foraging will provide some, but you need gear, it can be time consuming and the government will frown upon any illegal hunting or fishing without permits if that's required in your area. So you'll need at least some money for that.
Stinging nettle, along with other edible weeds, are a good source of food and have been used for survival.
You can of course grow your own food as well. Cabbage and similar is probably easiest.
