"Humans are not a mammal. All mammals have developed the ability to find a natural equilibrium with their environment, to coexist with it without depleting it's resources. Humans, however, arrive at an area, then they multiply and multiply, and when they have consumed everything, they move to another area. There is another organism that acts like this. A virus. Humans are a disease, a cancer eating away at this planet. A... plague, and we are the cure." ~ Agent Smith, The Matrix

I've always loved that quote.
