The earth's population exceeds 6 billion and rapidly going up to 7 billion.
In my view , I'm helping to keep that boom in check .
Howard, you are not thinking like a Ph.D. You've offered a reason for your choice, not a justification (reasons are not necessarily support).
Are we to understand that you don't want to sire children because you want to "help?"
Look here, old bean, you seem to have fallen into the Malthusian fallacy of inserting either a moral or pragmatic value into your refusal to participate in the natural phenomena of procreation and its concomitant population growth. For countless millennia, continuous advance in human population follows the natural order of things -- it is value-free (reproduction is a result of selective fitness, wherein value-laden notions over social/moral matters do not apply). Consequently, so what if an ever-increasing population leads to catastrophe?
Howard, as a bare branch and barren fig tree, please consider this insight about your arboreal cousins:
Just as trees in a forest that are close and cramped to each other compete for resources such as water, air, and sun, for the very reason that each endeavors to rob the other of these resources by competition, each forces each other to shoot upwards in this quest, and thus they grow tall, straight, and beautiful — whereas those trees which are planted far away from each other under no conflict or competition, grow stunted, crooked, and deformed.
Dear boy, social conflict, competition, and antagonism force the species to advance (e.g., unsocial sociability: "Man wishes concord; but Nature knows better what is good for the species; she wills discord").
If you are concerned with "helping," consider that your opting out of fathering children contributes to the fact that those in the upper quintile of intelligence and means are being out-sired by the rancid rabble. This is not a bad thing, per se, but the rabble think they matter when the grand designer has conditioned them for nothing other than fodderous material.
Moreover, wouldn't you agree that the world needs more Howards to offset the unrelenting, disproportionate influx of more Hamaads and Hakeems?
You are not "helping," quite the contrary.
Go father children. Yes, you'll be unhappy and miserable, but the content of your balls never promised you a schmoe's garden.
Good day.
