My only problem with your comment, and this is what has been eating at me for some time, is that you say this

Here’s the thing - this is a reasonable description of the vast majority of human existance.

Which is only from the human perspective. I honestly could zero fucks about what happens to the human race after all this is over. But the destruction of earth as a whole will be horrendous. You mentioned “remaining few animals” and that’s really where the problem is. We are destroying Earth, not humanity. And Earth doesn’t deserve that.
