What work are more land to grow food crops if all humans ate only vegetables or ate only meet?

If all humans ate only vegetables, more land would be required for growing food crops due to the need for extensive agricultural practices, including crop rotation and soil management. Conversely, if everyone ate only meat, the demand for grazing land and feed crops (like grains and soy) would significantly increase, as livestock require large amounts of feed to produce meat. Overall, a vegetarian diet is generally more land-efficient than a meat-based diet, as it requires less land to produce the same caloric intake. However, both scenariOS would still place considerable pressure on land and resources.
