> There is coming a point (it has already passed, in my opinion), where we can no longer justify our purpose for existence as "creating more humans."
Two comments. First, within evolution (true, a brutal and inhumane theory), the point of life is exactly to survive and reproduce. It is literally unnatural to deliberately choose to not have children (unless you don't believe in evolution).
Second, I presume that you don't mean for this to be taken to the point of nobody having children, that is, to the extinction of the human race. I get the impression that some eco-types think that would be a good thing; I deeply disagree.
>It is literally unnatural to deliberately choose to not have children
Something's being natural or unnatural has no bearing on whether it is right or wrong. I assume that when the OP says "we can no longer justify" they are making a moral claim, which means that saying it's "unnatural" to not reproduce is failing to be relevant.
