a) That's could, what about would? I think the time to organise less wasteful food usage is now, not when petro-shortage happens, then it's too late.

b) Why do you think that the future scenario I described is short-term dislocation? What happened in post-war Europe was short-term dislocation, because its causes were temporary (and local on a global scale), the causes of scarcity could be addressed. I don't think that applies to this future.
