Even if something crazy happens and the planet freaks out, some of us will inevitably survive. We're like cockroaches. Even worse really. We've spread over more of the earth than they have, plus into space.
Hell, it might even be fun to try and survive in a post-apocalyptic world. I'm damn good with old machines (my car is 23 years old and runs like new!), I can build and repair electronics in my sleep, I can manufacture my own ammunition (cast my own bullets, work up my own powder charges etc..), and that wife of mine is one helluva breeder (I give her one pop without birth control and she's prego
.. easy pregnancies, healthy babies, all boys so far too!).
Meh.. Either way, it'll all work out.
