These days, when people go out of their way to avoid mention of the P word, it's almost hard to believe that population used to be a mainstream issue.
Today's supervillains are soooo boring. If only they'd wear tights and touch entrapped damsels’ hair in a way that made us uncomfortable, we'd be up for patriotically pistol-whipping them, Captain America style. Instead we find out that Wall Street and ethanol -- a diffuse network of trading computers and a colorless inebriant, respectively -- are the reason billions are going hungry in the developing world. How are we supposed to launch a hideously expensive vendetta-war against that?
