I will read the rest of this after I finish eating my cake.
I can see war starting over this, and I don't mean the revolutionary type. China, by sheer numbers, could decide...hey, we need more food but don't have the ability to produce it...so we are gonna take some land (by invasion) and before you know it...WW3.
I'd be keeping my eyes on countries who are not democratic, and are suffering. They have the biggest chance of raising up a leader who will war for land.
Interesting stuff.
