This is exactly what happens. The highest quality land in a country is used for tillage. The less productive parts are used for grazing. This is how farmers make the most money. They’d be fools to use productive land for grazing and grow crops on poor land.

greenhouse gases and water usage are different issues i didn’t address here.

the usa is one of the “few parts of the world” i was talking about, that it is a bad example of sustainable farming.

yes lots of people cant understand that others can have other ideas about the world. in fact the historical norm for humans is for everyone in the same community to believe the same thing. this time of ideological diversity we live in is anomylous.

of someone says “i believe the earth is flat” most people will not accept that immediately. it’s triggering.

people are triggered by alien ideas. it’s not bad. it’s just being human.

or at a stretch or could be an argument against beef. but the question was about meat generally.

what kind of erosion?

are you thinking of “overgrazing”?

depends on the land. normally livestock are put on land which won’t grow anything else.

that’s true in a few parts of the world. it may not be valid at all, depending where op is from. in general livestock is the most sustainable land use food.

people have lots of different reasons. some don’t like the idea of killing a big animal with feelings and expressiveness. some because of how farms abuse or torture animals in some countries. some think Anibal farming is worse for the environment. some have religious prohibitions. some think it’s bad for your health. some people don’t like the taste or can’t afford it but don’t want people to think they are weird so they tell people they have a principled argument for it.
