Latest news from the Guardian:

Biofuels have forced global food prices up by 75% — far more than previously estimated — according to a confidential World Bank report obtained by the Guardian. The damning unpublished assessment is based on the most detailed analysis of the crisis so far, carried out by an internationally-respected economist at global financial body.

And as we all know, Friends of the Earth lobbied the government hard to get the biofuels obligation put in place. Environmentalism kills!
