Unlike just about everyone else here, I agree with this 100%. Population does not need to increase. Take either men or women and limit their number of children to 2; that would ensure a 1-to-1 replacement with the exception of early deaths. Once population decreases, maybe increase the limit to 3 if the numbers support it.
I’m not sure where I heard this quote, but it holds true here: “Save the earth; don’t give birth.”
