Zombie attack would be collapse of civilisation...

According to a BBC article Canadian scientists carrying out a "mathematical exercise" concluded that if zombies really existed and attacked we'd be damn near toast if we didn't kill 'em all real quick.

Money quotes:

If zombies actually existed, an attack by them would lead to the collapse of civilisation unless dealt with quickly and aggressively.

In their scientific paper, the authors conclude that humanity's only hope is to "hit them [the undead] hard and hit them often".

"It's imperative that zombies are dealt with quickly or else... we are all in a great deal of trouble."

"My understanding of zombie biology is that if you manage to decapitate a zombie then it's dead forever...."

The professor running the study sounds like a hoot. It would be interesting to take one of his classes....
