Maybe we should, at least in one area.

The Strasbourg-based European Parliament passed an amendment to limit the amount of transport fuel, such as gasoline and diesel, that can be obtained from food and energy crops to 6% of total energy consumed for transport by 2020, from 10% previously. … The new limit is meant to ease concerns about the amount of agricultural land that is turned over to growing crops for biofuel use….

There shouldn’t be any requirement, but this is certainly a step in the right direction.

Corinne Lepage, the lawmaker driving the legislation [says] “Taking indirect land-use change into account is important for the integrity of the EU climate-change policy.”

Because, among other concerns, “food prices could rise if crops are diverted from the dinner plate to the fuel tank.”  Our…environmentalists…need to understand this.  It diverts, here in the US, actual food crops—like corn—from the mouths of our poor to the gas tanks of “environmentalists'” cars.  And it jacks up the costs of food crops that substitute for corn.  And it jacks up the price of food that eats corn—like cows, pigs, and chickens.

Be like Europe.  At least in this.
