I want no such thing, merely offering my differing point of view here. It probably doesn't have relevance or any sort of impact in the lives of most people, but claiming that having children is universally moral could be challenged at the very least.

If nothing else, each child is another mouth to feed and will contribute to the carbon footprint of our species. While the planet could sustain more people on it, in our current climate of consumerism, i personally don't believe that the world needs to strive towards overpopulation and accelerated exhaustion of the resources that we have (amongst other things).
