Why your grand children and not someone else's?

Or put differently, would you forgo having children and grandchildren so that others can have this future you imagine?

There are lots of people who intentionally don’t have children, me included. I don’t have much hope, if we continue treating Mother Earth as garbage.

That said, your parent comment probably meant “our” grand children, just a guess.

I meant everyone’s grandchildren. I will be more careful how I say that in the future.
