“Left alone, human beings are a plague. They multiply relentlessly, consuming every resource, destroying everything they touch.”

“It's amazing how quickly nature consumes human places after we turn our backs on them. Life is a hungry thing.”

“Clear-cutting" was the word for what the Rusties had done to the old forests: felling every tree, killing every living thing, turning entire countries into grazing land. Whole rain forests had been consumed, reduced from millions of interlocking species to a bunch of cows eating grass, a vast web of life traded for cheap hamburgers. "Look, we're not clear-cutting. All we're doing is pulling out the garbage that the Rusties left behend," David said. "It just takes a little surgery to do it.”

“Sure, zombies can “be a metaphor.” They can represent the oppressed, as in Land of the Dead, or humanity’s feral nature, as in 28 Days. Or racial politics or fear of contagion or even the consumer unconscious (Night of the Living Dead, Resident Evil, Dawn of the Dead). We could play this game all night.But really, zombies are not “supposed to be metaphors.” They’re supposed to be friggin’ zombies. They follow the Zombie Rules: they rise from death to eat the flesh of the living, they shuffle in slow pursuit (or should, anyway), and most important, they multiply exponentially. They bring civilization down, taking all but the most resourceful, lucky and well-armed among us, whom they save for last. They make us the hunted; all of us.That’s the stuff zombies are supposed to do. Yes, they make excellent symbols, and metaphors, and have kick-ass mythopoeic resonance to boot. But their main job is to follow genre conventions, to play with and expand the Zombie Rules, to make us begin to see the world as a place colored by our own zombie contingency plans. […]Stories are the original virtual reality device; their internal rules spread out into reality around us like a bite-transmitted virus, slowly but inexorably consuming its flesh. They don’t just stand around “being metaphors” whose sole purpose is to represent things in the real world; they eat the real world.”

“Maybe human beings are programmed...to help one another, even to fall in love. But just because it's human nature doesn't make it bad...”

“Maybe they didn't want you to realize that every civilization has its weakness. There's always one thing we depend on. And if someone takes it away all that's left is some story in a history class.”

“You see, freedom has a way of destroying things.”
