Just to make sure you wouldn't miss reading all parts of the Spiegel-article I recommended yesterday. (No, I am not on the Spiegel's payroll; besides, I do not like the spelling style of their German edition).
Part 1: The Choice between Food and Fuel
Part 2: The New Chinese Appetite for Meat
Part 3: Snapping Up Land Across the Globe
Part 4: Can the Poor Afford to Eat?
