Real food Will go so expensive that will become Luxury only for few and off course davos elite.
But people will hunt down rich ones then If they can't get food you woun't eat in the expensive places If rest of the world eating bugzz, you need armed sercurity guard near by restoraunts.
But food prices are about go bullish parabolic bull run so many can't afford real food only frozen bugz or who knows what some dead cats or rats.
It's hard to understand what you're trying to explain. Even if an economic downturn occurs in the future, I don't think it will be as bad as you imagine. There is still land to produce food, poor people can rely on the results of plantations to survive. The possibility of something like in a Zombie movie is very small unless there are no more water sources in this world and the sun no longer rises.
