There is no way that agriculture can produce enough food in this climate to feed 7 billion mouths worldwide without a massive raft of innovation which is never going to happen. That means that people will be fighting in the streets over food.
If you study hydroponics and permaculture for even a little while you will start to grasp that nearly all the needs of a family can be produced in a very small area with minimal energy inputs, at a fraction of the costs that large agribusiness operates. This is why you will never see hydroponics promoted in the public sphere because it would mean the death of the big corporate food chain. Globalism and multikult are intimately tied up with the ideological framework that keeps these guys in the money year round. Once you have a cartel of supply outlets like the grocery store monopolies they have established in recent years you are essentially charging humans to go on living and they have no recourse but to pay you. Permaculture spins this whole process around and inverts it, putting you back in the drivers seat. This is why they are introducing the Codex Alimentarium worldwide now.
