Only 16% of agricultural land today is used directly for food, providing 83% of calorie supply, while 80% is used for livestock, providing 17% of calorie supply [0]. Not all land used for livestock is usable for food crop agriculture. Though I suspect it still gives us plenty of margin. If the population stays constant, we could probably deal with a 50-75% yield reduction without using more land overall, but gradually switching to a more plant-based diet. So, good news, we're not fucked yet. There are many other solutions other than vegetarianism. Changing the ways we do agriculture, switching away from industrial processes, could greatly increase yield. Education in general about soil and plant ecology would probably help a lot globally.
