To feed a person on an all plant-based vegan diet for a year requires just one-sixth of an acre of land.
To feed that same person on a vegetarian diet that includes eggs and dairy requires three times as much land.
To feed an average U.S. citizen’s high consumption of meat, dairy, and eggs requires 18 times as much land.
This is because you can produce 37,000 pounds of vegetables on one and a half acres but only 375 pounds of meat on that same plot of land.
