I'm not sure I agree with your link completely. Most European and North American nations are actually below replenishment levels. Replenishment levels for a given population are about 2.5 children per woman, on average. Yes, the amount of humans on the Earth is pretty large, but this is the one time in history where the elderly have outnumbered the young, and the median age is higher than it's ever been.
Or to quote Gandhi, "There is enough for everyone's need, but not everyone's greed."
God's first command, ever, was to be fruitful and multiply. I don't think he was kidding.
