As a supplement to a family's food supply, hunting and foraging are totally insufficient.You can't really make that claim without quantifying the degree of supplementation in question. And that's an unknown. So really this is all just speculation. But I can say that for myself, I'd rather have the ability/knowledge/skills to acquire food by hunting, trapping, foraging, fishing, etc. than not, all things being equal. If you want to take a defeatist attitude and not pursue those things, well... that just means you'll be one less person I'll be competing with for food eventually.
I just posted to provide the insight that, this isn't going to ever matter to our situation in any significant way. We have to support/restart our commercial food chain, or its going to get very bad.
I think we're ultimately talking about two different things here. Of course we have to restart the commercial food supply chain. That, to me, goes without saying. It's also somewhat irrelevant to that I'm talking about (which I think is different from what you're talking about). I'm talking about things to do in the interim for base survival... until the commercial food supply chain is working again. It sounds like you're assuming that we're talking about depending on hunting/foraging/fishing etc. as the default way of life for perpetuity. On that point, I agree with you... it's not reasonable to sustain a population of our current size for an indefinite period of time.
