If we use livestock feed for biofuels, what will the cows eat?

Around one-third of all biodiesel produced in the U.S. is made from waste feedstocks like used cooking oil, animal fats, and inedible corn oil. But few waste feedstocks are really wastes; none of...“Waste” biodiesel from corn oil probably drives up corn production and could have resulted in 500 thousand extra tonnes of CO2e emissions in 2017.
