So does that mean you think it’s likely that we will spread to other planets without spreading ecosystems? If we spread ecosystems it seems likely that we would also spread at least some wild animals. And I think we have good reasons to do so—to promote good atmospheres and other ecosystem services.
I feel pretty skeptical that humans capable of going to other galaxies would not have realized the inefficiencies of meat and would still not have made competitive substitutes.
