U.S. food production dominates land, water and fertilizer use, with beef being the main agricultural resource-user per kcal or gram of protein produced. Our speaker will offer a possible definition of "sustainable” beef as that subsisting exclusively on grass and byproducts, and quantify its expected U.S. production as a function of the extent of pastureland use. Utilizing all the pastureland U.S beef currently uses can "sustainably” deliver ≈ 45% of current beef production. Choosing to forgo the less productive half of the U.S. pastureland, thus "rewilding" ≈135 million lower-yielding hectares, can still deliver ≈ 43% of current beef production.
