Paul West at the University of Minnesota in St Paul and his team looked for "leverage points"--areas with big potential to change how humans grow food. They focused on the 17 crops that consume the most resources and that represent 86% of the world's crop calories. The study is a "high-altitude view" of what it would take to feed a planet full of people, says Greg Asner of the Carnegie Institution for Science in Stanford CA.
