This is degree generally more than diss. I paid £3k a year to learn about terrorism, joy!
I was considering this earlier, well something similar anyway. We've become a species that can adapt spectacularly quickly, and more over adapt beyond our natural capability. We augment our environment to our needs, we improve ourselves beyond our means with medicine.
That got me thinking, we've become rather resilient. It'll take something absolutely catastrophic to destroy us. Either so massive a change it undermines our ability to adapt to it, or something so quickly catastrophic we don't have time to.
And because of that, even things like widespread nuclear war would have to literally wipe the population away, which is reasonably unlikely, to destroy our race.
