If people don't want to eat shit and survive the coming storm, you'll pull your finger out and work something out. You don't necessarily have to do the hard yards yourself. You've heard of the barter system? You bake cookies and cakes someone tends your garden. Or, they tend your garden for a % of the harvest. Even if you live in an apartment, you can organise a community garden. Somewhere, someone has a plot of land. I look at solutions, no problems.
I have planned and organised what I need to do for my family. I've got heaps of veggie & fruit seeds and a bucket load of non-perishables until the crops grow.
There is a solution for everything. If you say that there isn't, you may as well just give up now. It's not about doing it now, it's about learning and preparing for the worst.
Better to plan for the worst, and hope for the best.
Better to have one and not need it, than to need it and not have one.
