These transformations are tied to the changing American diet. Since the early 1980s, America’s per-person cheese consumption has doubled, largely in the form of mozzarella-covered pizza pies. And last year, for the first time, the average American ate 100 pounds of chicken, twice the amount 40 years ago.
I dont think you realize thr magnitudes of difference in efficiency between eating plants vs eating animals that eat plants.
Growing plants for humans to eat is negligible and probably wouldn’t be an issue even if our population exceeds 100 billion
