I get where you are coming from, I read all your comments here.
You are making an assumption that children just are a net negative.
As others have mentioned the carbon footprint of a child is miniscule compared to an adult,
They are not driving, flying, owning homes, etc for a while, and many never will.
One of those children could very well be the solution to that, and many other problems.
As for moral high ground you insist that you are better for having made the choice not to have children, as you see their opinions as less than and not worth listening to, as they have had children.
