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.
This may happen due to climate change, where more extreme weather patterns interrupt food production in different parts of the world. We might see more flooding and droughts which wipe out crops, so it is more important than ever that we keep global supply chains open because we don't know when we might rely on other nations to rescue us. There have been plenty of lessons throughout history, even the bible mentions plague and pestilence, which we may not be able to solve quick enough. You mention insects as a possible food source alternative but the population numbers have plummeted as well, so that option could be out the window. Those who are richest, as always, will be able to weather this storm the best.. but the storm is slowly rolling in on all of us, it might just take decades to play out.
