Seriously, folks, building a stockpile of long life food right now might not be a bad idea.

Most cities have only a few days worth of food in them, thanks to the brilliance of "just in time" inventory. Our economy is so interdependent that if one thing seizes up - say, fuel supplies - everything else will jam up behind it very quickly. Coal supply goes down - no electricity. Fuel pumps don't work - refinery doesn't work - transport becomes very hard to arrange - food becomes scarce... etc.
It could take a few weeks before things start trickling through again.

Most disaster agencies recommend everyone have at least one week worth of essentials on standby. Food, water, and don't forget the toilet paper *.

I am NOT forecasting the end of civilisation as we know it. Maybe nothing like the above will happen. But I reckon that for the next 1 or 2 years, there is a higher than usual chance of things going a bit haywire.
