There is a certain level of meat production that uses only waste as fodder, land that has no other agricultural value, and doesn't require destroying areas of high biodiversity to make room for our animals. The current global levels of meat productions are extremely far away from this. We cut down vast swathes of forests to get cheap farmland, both for grazing as well as for producing grain and soy as fodder.

The Great Plains in the US are huge. Lots of cattle grazing out there in an environmentally sensitive way. Most of the feed is hay cut from fallow farmland. Maybe what you’re describing happens in South America, but it’s not at all what happens in the US.
