The UN food and Agriculture Organization estimates that althouge there is enough grain alone to provide everyone in the world with 3,600 calories a day, even taking account of increases in population growth (i.e. 1,200 more than the UN's recommended minimum daily intake), the number of people living in hunger continue to grow.
Furthermore, critics note that the Third World, where the majority of malnourished people live, produces much of the world's food, while those who consume most of it are located in the western world. Meat consumption tends to rise with household wealth, and a third of the world's grain in used to fatten animals.
