And what about the negative experiences? Especially for the vast majority of poor people?
I agree that in the end the industrial revolution was a wonderful thing. But not because of the number of people.
And the hosting of those 7bn people has caused irreperable damage to ecosystems. Why are you so happy for the extinction of entire species, but not for 6.9bn people not existing?
Why should I care about "entire species"?
I'm happy that we made smallpox extinct. Likewise, I'd be ecstatic if we decided to drive the mosquito out of existence. I'm all for caring about nature, but towards the end of improving human welfare. Where saving some random species conflicts with saving people, choosing anything but the latter is just monstrous. Sentient creatures (only humans, currently) have moral worth. Non-sentient creatures, none.
So why are you happy for the untold billions who will never be born because we've ruined out planets ability to sustain us?
Sustainability is about being able to give future generations the same quality of life that you have had. And society as it stands is not sustainable

Climate Change is another topic but there seems to be some movement as well on that front.
