Can the world support more vegetarians than meat eaters?

Unfortunately, the answer is not as simple as a mere calculation. The United States uses more than one-third of its land for pasture. For more than 100 million people in arid regions, grazing livestock is their only source of livelihood. Half of the land area in the U.S. cannot be used for growing crops and is used as grazing land instead. If cattle, sheep and goats were not grazed on this land, it would be of no use for food production.
