IF...

How would you have not allowed it? You are here for a reason\purpose, as we all are. You have no choice to accept this fact, even if you don't approve of it. The majority of humans breed to have children, so that is just the way it is. This is largely founded on religious notions anyway, to populate the earth abundantly. Blame the wrongheaded notions of religion and what's in scripture, if you aren't happy with this. Take another path or route otherwise, because the one you are following, is obviously not working for you....
