@freemo interesting matter. We do not know how to survive to a total global disaster that would let us living "la vida loca" in a wild forest, years after this dammed pandemic! Hehehe!
Hunters an butchers would be the most valuable assets for our colonies, as always were. My wife and i have a little experience fishing. Diferent kinds of knots, baits, fishes ... My father and hers were hunters, had hunting shotguns but they never taught us hunting, that knowledge will disapear. My son wanted to know hunting but i failed in that because my father did not tramsmit that knowledge to me... My wife's parent knows a lot of birds, even their trills, mushroom, kitchen gardening, cattle raising. In short, they lived another kind of life, they were in contact with the natural medium.
