In case you are unaware we were losing babies by the truckload just a century ago. There was death, but we all forgot since we dont see it anymore.

I am aware. And that is progress that is good for humanity. However air quality is decreasing and global temperatures are increasing.

A century from now we'll be losing a truckload more babies

Its like we rose to the top of the bell curve and are now hurtling down the other side

Where exactly is air quality decreasing? At least in developed nation air quality, and water quality, improved over the last decades.

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

> 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.

Thats such a selfish outlook. The same outlook that leads to overfishing, soil erosion and monoculture agricuture. We think we are optimising for human welfare and happiness whilst simultaneously destroying our ability to give future generations the same prospects that we have.

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
