i know i'm probably gonna be attacked for saying this, but i think the growth of the old population is just as dangerous, if not more dangerous, than that of the young. as science keeps finding new ways to prolong the grave, we get to the point where 70 is still "middle age" and living to 90 or 100 is no longer a particularly noteworthy feat. lots of people are still working and contributing at advanced ages due to arthritis medicine and better heart-health regimens, but you also have an exponentially growing segment of the populace that's a wealth of old-timey stories to tell the new generation, but offers little or no practical contribution to the world, they take in resources but have ceased to put anything back into the system. i honestly think we have to figure out a way to either accommodate or deal with this portion of the world's population, or else they will soon become a burden that will break the backs of the newer generations of the human species.
So remember, when you're feeling very small and insecure,
How amazingly unlikely is your birth,
And pray that there's intelligent life somewhere up in space,
'Cause there's bugger-all down here on Earth.
