Why can a given area of land support more vegetarian humans than omnivorous humans?

Answer 1

The production of meat requires far more water, land, and fossil fuels than would the production of the same amount of plant-based food. Up to 16 pounds of grain are needed to produce one pound of beef. Out of the huge amount of pesticide used on these grains, a percentage ends up on the food is destined for animals that are used to produce meat, milk, and eggs. The pesticide concentrates in the bodies of the animals. This pesticide is then eaten by people, and fed to their companion animals. The meat industry generates nearly one-fifth of man-made greenhouse gas emissions, according to the UN Food and Agriculture Organization, and many scientists now believe that in the wake of a changing climate, the switch to a largely plant-based diet is necessary to avoid famine.

Besides costing in terms of water and fuel that much of the world cannot afford, a pound of ground beef will cost $2.88 this year in the United States, where its production is highly subsidized. It provides 1,152 calories, nearly 91 grams of fat, 78 grams of protein, and no fiber. A half pound of lentils mixed with a half pound of brown rice costs about $1.38 in the United States. They provide 1,587 calories, 8 grams of fat, 88 grams of protein, and 77 grams of fiber.

Plants produce many more seeds than animals do offspring, so plants are replaced faster.
