In this National Geographic feature on the future of food, a map that illustrates how much of the world’s crops are grown for people to eat directly (green), compared to crops grown for biofuel or to feed animals.

“Only 55 percent of food-crop calories directly nourish people. Meat, dairy, and eggs from animals raised on feed supply another 4 percent.”
