The World Health Organization's Health and Environment Committee (WHO) recommends the transition from animal resources to plant resources, with an emphasis on cereals and legumes. On one hectare of land, 2,000,000 calories in the form of wheat can be grown, but when plants are fed to animals whose meat is subsequently consumed by humans, the yield is only 500,000 calories (about a quarter). Half of the grain crop is used (in the US) for animals.
