How do u want the world to end?
Heres how I want it to end :
RIGHT! Anyways, in about 50 years a crazy scientist man extracted some VELOCIRAPTOR DNA from... something, amber? Sure. Why not? (Shut up, it's my future.)
BUT! It all goes horribly wrong and they end up growing far bigger than what skeletons would suggest and have grown to be like, OVER 9000!!! miles tall, but just under 10ft really.
THEN! They manage to escape their enclosure because they have the strength of at least FOUR men and we used chicken wire to secure them. Bad times.
SO! The horrible, giant 'Raptors get wild and start eating people and chickens and dogs and killer whales, and people start to get really scared and paranoid and they start having searches like this:

AND! The world changes, Maths as we know it evolves:

FINALLY! MySpace (Formerly known as Western Civilisation) and Russia blame each other for this, even though it was Yahoo's (Formerly known as Japan) fault and both of them go crazy-insane and declare war on the rest of the world and end up nuking everything.
HOWEVER! Cockroaches can survive and do, but only after mutating to become super intelligent and huge creatures. They build space rockets out of raptor bones and fly to another planet as the radiology levels on Earth are too high to get good TV reception.
BUT! The cockroaches fleet of rockets gets attacked by crazy space-rexes who eat them all and then Earth itself for dessert, for they truly are OVER 9000!!! miles tall.

THE END.
I can't wait. I hope I don't get eaten too early on.
