I suspect that not many have those knowledge and skills. I guess they will learn on the job. The rat plan will lead to drastic reductions in consumption so I do not see any alternative to more basic living.
AFter 9/11 I wondered if it would be necessary to leave the city and move into the hills. I swear I plotted this move. Take my children with me.
I still think about it. I can’t build a fire without a fire source (not real keen on rubbing two sticks together), and I don’t know that I could catch an animal and roast it on a spit, but do believe I have enough knowledge to forage for berries and other edible foods.
Meanwhile, my citified friends would roll over and die, pitifully spoiled that they are.
