Or at least we think nothing of it in the West. If the price of our breakfast cereal goes up because we’re diverting agricultural production to ethanol or biodiesel, it’s an annoyance. But if the price of corn or flour doubles or triples in the Third World, where according to Mr. Brabeck-Letmathe people “are spending 80% of [their] disposable income on food,” hundreds of millions of people go hungry. Sometimes, as in the Middle East earlier this year, they revolt.
“What we call today the Arab Spring,” Mr. Brabeck-Letmathe says over lunch at Nestle’s world headquarters, “really started as a protest against ever-increasing food prices.”
