Mark Steyn's variant of Mike Lester's lesson:

[F]ood rioting is a planetwide phenomenon, from Indonesia to Pakistan to Ivory Coast to the tortilla rampages in Mexico and even pasta protests in Italy.

So what happened?

Well, Western governments listened to the ecowarriors and introduced some of the "wartime measures" they've been urging. The EU decreed that 5.75 percent of petrol and diesel must come from "biofuels" by 2010, rising to 10 percent by 2020. The United States added to its 51 cent-per-gallon ethanol subsidy by mandating a fivefold increase in "biofuels" production by 2022.

The result is that big government accomplished at a stroke what the free market could never have done: They turned the food supply into a subsidiary of the energy industry.
