No we don't. IIRC, birth rates are dropping everywhere and the world population in on track to plateau mid-century before it declines.

And also "uncontrolled and unsustainable" living standards growth. When you have huge portions of world population wanting to live like in the west, and not only for basic stuff like hygiene and schooling. And meanwhile people are decrying that we're too many, too many people are born. Which basically translates to more women should take more pills. Children of men, the movie, comes to mind.
