Although he mentions the caveat that “That said, before we become too gung ho about eliminating natural ecosystems, we should also remember that many other humans value wilderness, and it’s good to avoid making enemies or tarnishing the suffering-reduction cause by pitting it in direct opposition to other things people care about. In addition, many forms of environmental preservation, especially reducing climate change, may be important to the far future, by improving prospects for compromise among the major world powers that develop artificial general intelligence.”
I think he also pointed out somewhere that most of expected future wild animal suffering wouldn’t take place on Earth, and getting societal support to prevent space colonization-induced future wild-animal suffering is more important.
