Pork: the first unsustainable meat?

(via Reddit) The idea that the amount of meat humans produce being problematic isn't a new one.  It was one of my major motivations for becoming a weekday vegetarian -- around half of the plant food humans grow is used to feed livestock, which raises questions about the ethics of global food shortage.

Unfortunately, the majority of Westerners are unlikely to give up their bacon willingly.  Fortunately, it looks like the forces of economics might make them.  The NPA ("the voice of the British pig industry") report that, next year, a global shortage of pork and bacon is unavoidable.

The Huffington Post point out that increased droughts in North America and Russia caused grain crops to fail, increasing the price for grain produced.  They add, half of the country's counties have been labeled natural disaster areas by the Department of Agriculture.

I suppose it's a little grim of me to hope that this foreshadows a global-scale collapse of industrial livestock, forcing us onto more sustainable, less environmentally damaging food sources.  Then again, I can go grimmer:  If the world governments' responses to the failing Entertainment industry are representative of their future approach to other luxuries, America might face its ultimate collapse in a mad struggle to fund steak and bacon until they've sold off everything else and have to stop trying.

What I'd like to see, I think, is a polarization.  I'd like to see most people resign themselves to the reality that meat will have become a sometimes food, and either shift totally into vegetarianism or only occasionally seek out meat. Then, the super-macho pseudo-darwinist food chain fanboys that think the consumption of weaker animals is what defines humanity can all learn to hunt, and go live on the edge of the woods and get all their meals shooting things themselves.
