Biofuel: filling your tank with hunger

The UN is calling for action to avoid the "silent tsunami of rising food prices which threatens to push more than 100 million people worldwide into hunger" (http://www.un.org/). Protests against rising costs of basic foods already started in Haiti, Mexico, the Philippines, Bangladesh, South Africa.... Sub-Saharan Africans continue their decades-old silent protest, dying slowly, quietly, dryly.
I recall now the bad feeling I had last year when I read about Bush's visit to ethanol-driven Brazil.

Biofuel production is said to be responsible for at least one third of the recent increase in food prices. It was already being called “deforestation fuel”. Now it’s also “hunger fuel”.

But it’s bio. «Quand je dors chez mon copain, on mange tout le temps bio» (Sanseverino, «Cette conne m'ennuie»).
