Improving Food Security by Lester R. Brown

REVE - Regulación Eólica con Vehículos Eléctricos -: "From 1950 to 1990, world grainland productivity increased by 2.2 percent per year, but from 1990 until 2009 it went up by only 1.3 percent annually. Despite some impressive local advances, the global loss of momentum in expanding food production is forcing us to think more seriously about reducing demand by stabilizing population, moving down the food chain, and reducing the use of grain to fuel cars."
