Yeah, sometimes I think people lose track of why they support environmental movements. I've had people question my choice to have kids along these lines before. I just don't understand it - surely we only care about all this stuff because it is observed by humans? For humanity to continue, someone has to have children.

I can sympathise more with the idea that humans are destroying everything and life won't be worth living for my descendants. But that feels like giving up on the possibility of humans. I don't want to do that.

In any case, it turns out that global fertility rates are in freefall and we're facing population decline faster than anyone predicted.
