After zombies run out of brains to eat, or if they are the flesh eating variety and they run out of people to eat, what happens to them? Do they starve? Can the starve to death? Do they eat each other? How long do the surviving humans have to survive until there are no longer any zombies?
Zombies should only last a few years. Everything needs energy and without it zombies will eventually stop. Unless they convert to vegetarian and start eating trees and grass. Plus since zombies can't repair any damage eventually they will fall to pieces after being worn down by the elements.
Do I need to point out the illogic of trying to hold something that already violates all known scientific laws to... scientific laws?
But as an intellectual exercise - if they're merely the reanimated bodies of dead people, their souls are elsewhere, therefore they're not responsible for the behavior of their bodies minus their souls. Would you say that's a fair assessment?
In the last hundred years, the human race has expanded from one to 7.6 billion people. We're like the mammalian equivalent of cockroaches. I suspect we're being bred and harvested by monsanto as zombie soylent green already.
Zombies don't violate all known scientific laws. I've yet to see a Zombie on fire that did not burn up. Nor have I seen a zombie take flight (sounds like a bad Syfy movie lol). So if they can follow some laws then certainly they can follow the laws of energy.
I've seen something close. They were vampire zombies. A memorably bad movie, that one. Starring the chick who played the female Klingon in STV. *edit* Here you go. The actress's name is "Spice," and that movie was The Dead Undead
