The percentage of deaths related to malnutrition have declined over the past 40 years. In 1970, approximately 33% of the developing world was malnourished. In 2010, approximately 20% of the developing world is poorly nourished. If we were to put our concern toward micro and macro nutrition and less emphasis on greenhouse gas output, the improvement might even be greater. Dithering over GhGs with schemes such as biofuel ends up hurting those it is supposedly meant to help. Biofuel production steals from food production.
About 5 per cent of the world’s grain production is now going to make motor fuel rather than food, with the result that rich farmers like me get better prices, but poor Africans pay more for food. Yet that 5 per cent of world grain has displaced just 0.6 per cent of world oil use, so biofuel is hurting the patient without even stopping the nosebleed.- Matt Ridley, The Tourniquet Theory
