Actually, it doesn’t so much. It just requires putting people back on land with hoes and seeds and manual labor. They aren’t doing anything anyway, and the secret is to dry the food for storage or leave it on the hoof until needed. That means more local grain mills running on windpower: and those can be built locally from wood and stone. We know more about production of organic food now, including composting all the crap from cities, as well as intercropping.
Then, there’s the minimum industrial tech required for solar charging, lead acid bateries and small electric tractors: not because we couldn’t run them on alcohol, but making them electric cuts down on oil leaking on my vegebles…
There’s a lot we can do if we want. We just let the “always low prices” shift spending to crap nobody needs.
It’s fun to bitch about it, but the majority either don’t know, don’t care, or are making a living (or a killing) from pretending not to know or care.
The tide of awareness is turning, but the beach head is sinking.
