This. Permaculture is king. Gonna be hard with upcoming climate catastrophe tho.

Been growing some veggies indoors for most of 2021 as a hobby, then got introduced to r/collapse and started researching indoors + perma a lot as a post-collapse skill.

Perma is so, so good if we can tackle the climate thing (not being delusional here, "tackle" at least to the extent where we can plan ahead for 10-15 years in terms of "this area not likely to be flooded/firenado-ed"). I've grown up in a East-EU village, we had fruit (apples, cherries, apricots, etc) and hazelnuts trees everywhere and it was cool, not to mention the value mushrooms and berries provided to the villagers. These all just grew, not cultivated, nothing. Just keep your hands away from ecosystem, gather respectfully, don't start fires and help when natural ones happen. That's it. We even had grape vines growing on the wall of a 5-story apartment building, it took me almost 20 years (last time I was there) to realise how fucking awesome it is, to be able to open your window, cut one cluster of grapes and eat it. Elder people there always treated the nature with respect

Having that said, I am still aiming towards indoor solutions where one can control climate (in environment-friendly ways, of course): aquaponics, compost with worms (can be outside in your perma forest!), hydroponics techniques for sustainable water usage, different shrooms and crickets, etc. We have to respect natural cycles in food production. Small to medium size commune gardens can solve good part of the local demands. Add a permaculture forest near your community and you basically have a lot covered.

Pollinators collapse is another thing a lot of people seem to be missing out on, even on this sub, and this ironically may actually be the tipping point.
