bacteria!!

I got thinking about over population and what damages this does to the planet. Here were my thoughts.. Looking at the earth as one living organism, we humans are no more than an over-evolved super bacteria that builds up and makes the earth ill. Like a cancerous growth on earth, thats what i imagine the unnatural city lights and built up constructions looking like from outer space. I might explore the concept that when there are natural disatsers it is like the earths attempt at defeating the cancer, like our bodies natural antibodies would try to do.

I think this could definatly be an interesting thought to play with. I will contrast modern society with bacteria, rot , disease and mold..
