A 'time bomb' for world wheat crop

A 'time bomb' for world wheat crop - Los Angeles Times: I have been keeping up with reports like this over the last 18 months or so. It had been confined to Central Asia, but now, I'm starting to get nervous. Between this and increasing amounts of corn acreage being converted to ethanol production, you might actually see food shortages in the United States. We haven't had anything resembling a true famine in our recorded history; this is no time for a first.
