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