picked this up off slashdot:
Stating the obvious: "
Two scientists write that obese people are disproportionately responsible for high food prices and greenhouse gas emissions because they consume 18% more food energy due to their greater body mass -- and require increased quantities of fuel to transport themselves and the food they eat. 'Promotion of a normal distribution of BMI would reduce the global demand for, and thus the price of, food,' write the authors, Phil Edwards and Ian Roberts of the evocatively named London School of Hygiene & Tropical Medicine."
thats something to think about...
