'"Our scenarios suggest that global trends of increasing body mass will have important resource implications and that unchecked, increasing BMI could have the same implications for world energy requirements as an extra 473 million people," they write. "Tackling population fatness may be critical to world food security and ecological sustainability."'
Yep, yet another study. Fat people 'require' more resources to sustain their weight, evidently not just food but energy, water, space (sit in an airline seat beside one of these gaia destroyers for evidence of the space claim).
Anyhow, the implication is that the US, the fattest nation in the world, needs to be put on an enforced diet to save the world.
