I do believe prices might double, (bad enough) but i do not understand where the 10 fold is coming from. But if so, rice and beans are going to be popular as well as wild foraging and stealing from people's gardens.
I am doing my bit by planting more potatos. Good plan to move some sunchokes. I have planted some tobacco early, i thought if prices are going to go up, people won't have money for tobacco but be stressed and want to smoke even more. Barter material.
I believe and see most capable people are already giving it their best and cannot do much more than they are doing already. Adding more crisis talk in an overly alarmed society will not change a lot i think.
I checked a bit on youtube and saw AI slob about growing gardens..People generally overestimate what they can achieve, growing a garden full of food with no previous experience... They come across 100% sure they will have super gardens, better than those socalled gardeners, because they're winners. But they'll learn trying. And then in disappointment look for guidance. People's focus will shift to food growing as insecurity strikes and prices rise. And as chemical inputs will become too costly for many, attention will automatically shift to how to do local and biological, maybe even work with nature, not against it. Permaculture movement can and should flourish. I would also like to point out to people here that seed saving has never been more important. Plant some extra, and let the biggest plants provide seeds, share extra seeds of this year with friends willing to really grow.(in doubt do not share, but keep them for later)
But back on topic if the price of food goes up tenfold, anything can happen and none are good.
