Richard Gregg (social philosopher)

"The generally accepted computation is that 2½ acres of land are required to provide a minimum adequate diet for each person, by Western standards anyhow. On a vegetarian diet it has been estimated that 1½ acres per head may provide enough. The reason for this difference is that animals grazed for meat-eating purposes require about 15 times more land than is necessary to raise an equivalent amount of nutrition in the form of grains, vegetables and fruit for human consumption. This means that India, on a vegetarian diet, is living far more wisely within its own land resources than are the meat-eating peoples."
