I'm in a position unlike many others. I'm by no means a prepper, but I have adequate resources which I've cultivated locally to forage from in abundance and and hunt in abundance.
There are deer regularly seen walking in the fields at dawn and dusk nearby, a huge amount of rabbits, pigeons and squirrels. Many of which I've hunted, shot with either a catapult and lead ball at close range or with a .22 rifle at range.
Many of the forageable items I've planted in the area are perennials and many are root veg, which unless you know the leaves, you'd walk past and not know.
Callaloo, carrots, potatoes, parsnips, horseradish, kale, onions, garlic, sorrel, various berry bushes (brambles, blueberries, raspberries), various trees in the area which now produce fruit (apples of varying degrees), pears, plums, damsons, walnuts, hazelnuts, chestnuts, and if times are rough, acorns can be used too.
For fish and the like...half a days walk at a slow pace, or 3 hours at a reasonable pace sees me at a spot I can trap crayfish in ludicrous abundance, catch trout, and shoot ducks and geese.
If the worst happens. We'd be shit out of luck for growing stuff like wheat and grains because the soil couldn't cope with it on a repeated basis, however, not many in my village know about what I've planted, where I've planted it, and when to pick it.
At worst, we'd survive a few months before winter kills off the crops, then comes the struggle, surviving on nuts and whatever hunted meat.
