While I agree, the "meat is not sustainable" argument is literal, and evidenced in beef prices rising as beef consumption lowers over the past years. Beef is moving along the spectrum from having had been a "staple" to increasingly being a luxury.

The US never gave up eating lobster either, but many here have never had lobster and almost nobody has lobster even once a week. It's a luxury which used to be a staple.
