Nature's Other Way

We're all adults here, right?  Or at least our versions of adult?  We're all enlightened and fully aligned with the live-and-let-live ethos, right?  Okay good.  Lemme say a thing now that is completely aside from all that.

 I do this little disclaimer because when certain topics are brought up, they're instantly derailed and then slammed into the popular narrative that everyone seems to want to talk about and I'm not here for that end of it.  I'm viewing this subject from mechanical perspective, not a moral one.  Maybe not so fun for most, but since when have I ever been fun?

I think the world has pretty well neared critical mass in terms of population and I'm thinking that the human instinct to procreate might be beginning to shift. 

Since about forever, sex drive has kept our species on the planet.  It's an instinct.  If it were something that humans could procrastinate about, we would, which means it would never get done.  There would be so few of us.  If instinct were not driving the train, the train would never leave the station.

But it does seem procreation is on the decline, and we have an increasingly large number of people who have genders and sexualities that don't fit traditional definitions.  It seems homosexuality is on the rise - probably at its peak.  Things in this regard are being redefined all over the place and we're pretty far away from the nuclear family model of the 1950's, and not just because we're more enlightened - it's also because we have a thousand monkeys sitting at a thousand typewriters inventing every possible combo, which is great, but most of those combos won't ever procreate.

Let me stop here for a second to say again I have zero judgement about any of the moral stuff involved here.  What I'm wondering is, is this all a biological response to our environment?

Is there some kind of magnetic (okay not really magnetic) shift inside our brains that dulls our need to procreate?  Like the birds need to fly south in the winter, maybe when we look around and see how many of us there are, there's a subconscious shift that happens in our little pea brains, too.  Our whole existence on this planet is owed to the instinct to procreate.  If aliens were able to come here and rewire us all to just forget about it, all they'd have to do is wait it out and the planet would be theirs.  THAT'S SUPER CLEAN!

Okay - a little bit carried away there for a sec but I do wonder if there's some sort of human mechanism that responds to overpopulation and if we might be experiencing it right this very moment.

All right don't worry about it.  These were just some ideas.  Sorry for the interruption.  Back to taking sides on the issue everyone!
