Or eat grassfed beef, which is grown consuming human-inedible grass that grows for free, instead of being fed human foods that have to be farmed.

White Oak Pastures even claims to have a negative carbon footprint[0], according to a report by a third party which, if I remember correctly, also authored the report behind one of the vegan burger's sustainability claims.

Grass-fed beef is no real solution to the grain shortage. For one the meat is more expensive, for another there is a limit to the land that can be used as meadows but not for other crops.

Can you use the meadows above the tree line for agriculture? That’s what they eat during the summer.

As I said, there's a limit to such land, and a limit to how much cattle that can be raised on that land.

There's a reason why cattle farming went from extensive to intensive methods.

What? There’s a limit to highlands? That entirely depends on where you live. ;)

Limit? The US federal government has over 100 million acres of public land for animal grazing.

That is another problem.

And it anyway affects only the US, a very small fraction of world population or land area. That the US is a very large part of the problem, e.g. importing beef, does not help.

If that were such a great and practical ressource, they'd be overflowing with cattle or sheep herds like in New Zealand. But it's not. Also the density of grazing isn't that great.
