You need a lot of words to correct yourself, you may sound smart, to me you sound like a hypocrite. let me go ahead and try to summarize, what you actually try to say is: we should bear less children, instead of your first statement no children at all. On that we can agree.
Leave the earth for whom then? No one? Everything else but humanity? It’s such a destructive and pessimistic take. And no, we are not gonna get along then. I have a bit more faith in humanity and our intuitive ability to adapt.
