This. I do not see off-world animal farming as a real issue. It’s such an energy and resource inefficient way of making food. Indeed, a prerequisite or a proxy indicator for Earth-independent sustainable civilization seems to be extremely good efficiency in food production. You can’t possibly be on Mars or make an interstellar ship and still have a thousand cows in it for making some cheese.
