While true, it's functionally irrelevant. Humans are animals, animals procreate. Telling people not to do it because reasons is going to be about as effective as telling them not to eat or sleep.
What I would like to see is a norm on numbers of children. Personally, I think that having more than the replacement number - i.e. more than 2 - is straightforwardly unethical given the stress our planet is under. But by the same token, 2 or fewer is fine. And it would be nice if those who choose to have none got a little more respect for it.
