Did you happen to notice what Hurricane Sandy did/is doing/will do to the "Megacity" of New York? And what was that Jesus said about the man who built his house on the sand? Not to mention that little bit about "...they were eating and drinking, marrying and giving in marriage, and they did not know anything about it until the waters rose and swept them away." The average Megacity, including the one I live in, is about 12 hours from starvation, or an even quicker death, at any given hour of any given day. Just ask them over at Breezy Point...oh, wait, that burned down, didn't it?
