If you fly over the country, you will see a bunch of green circles from center pivot irrigation systems mining "fossil" groundwater. All the brown spots outside of those circles are vegetated, but the only way to get human food out of them is grazing. By necessity there will always be a large amount of cattle grazing area. Feedlots should be ended as a practice- wasteful of feedstock and poor quality and nutrition of the output.
