A stable popolation is a healthy population.
If our population had a stable birthrate of 2 kids in every country, our numbers would stabilize. A population that is stable is a healthy, happy, and successful one. But alas, we humans will continue breeding ourselves into utter oblivion because "OMG, BAYBEES ARE GOD! I MUST HAVE THEM!" and "MUST OVERFLOOD THE GENE POOL WITH LARGE FAMILIES OF 3 OR MORE KYDS!" Not to mention "BUT IT'S MY "right" TO HAVE AS MANY CHILDREN AS I WANT! WAHHH!"/s
....We probably deserve to go extinct. We're no better than your average cockroach. Thanks a lot, guys. We couldn't have reached our inevitable doom without you. For those of us who don't have kids or only had one or two for replacement (as well as the future parents of only 1 or 2 kids), thank you. I'm glad some people have common sense and intellect. It's a damn shame that all of us will suffer due to the actions of the less intelligent. :(
