Yes, and? We're not using it for anything else. Saving 93% of the arid scrubland we use to raise cattle in the US wouldn't benefit us in any way.

OTOH, growing soy and other plant protein sources used for fake meat requires high-quality land and is extremely taxing on the soil.

As an interesting reference, take a look at how farmers in Brazil use deforested Amazon land to graze cattle only after depleting the soil to grow soy for a few years, at which point it is inhospitable to plant agriculture.

What do cattle eat in CAFOs, and how much of their lives are spent there and how much more do they eat there than when they are younger and smaller? And where does that food come from?
