While I think the environmental sustainability angle is also an active thing to think about here (because beef potentially involves less suffering for the animals, but relatively more harm to the environment), I did actually intend sustainability in the spirit of “able to stick with it for a long period of time” or something like that. Probably could have been clearer.
I took Tristan to be using “sustainability” in the sense of “lessened environmental impact”, not “requiring little willpower”
