So basically, we are a virus. That is my theory. We are here to fuck up the earth. We are decrepit filth. We are a rot on this planet. We suck up its lifeblood and turn it to waste. For the longest time, the earth has fought it off, like a healthy person fights off the flu. But we are too strong. There are too many. We are degrading the earth as fast as we can. Fuck global warming, that's a marketing ploy. If you can't look around you and find something wrong, something totally fucked up with this planet and with the way us humans run it, your gain? I guess. You can watch walls crumble and not see a thing. We are fighting over areas. Over territory. We want to do our job and we compete. Because we thrive off of this. And when this organism we call the earth is far too unlivable, we will spread like any good virus does. Contaminate a whole new species. Mars, the moon? Who fucking knows. But we're gonna. Or we will perish.
So, you might ask, what are these things we call good and bad? Why would we have religion? Well, it is so that we can further ourselves and propagate ourselves. We need to copy (sex) to survive. We need to spread (conquest) to fruit in the earth. We are like a mushroom. Our subways are spreading underground, we dig deep to get what we need, and we must remain on top of all of this to breathe, and to reproduce. Get it?

"We're devouring the lifestream, the round river, that biosphere from which our species evolved and upon which we still depend for subsistence.We are the snake feasting upon its own tail. "

and here's somebody (gooddrugguy) owning my theory (also from shroomery.org)

"I don't think so. Comparing a human being to a cancer is like comparing a ant bed to a pimple. Organisms exhist on this earth to absort energy, and that is exactly what we are doing. We construct all of our bullshit (dogma, architecture, ect) because that is just what humans do. Does this hurt the earth? I think you have to be one egocentric son of a bitch to think that human beings are any more disasterous to this earth than termites or moles. As an individual your perception of yourself is subjective, and while one guy might sit there and think in his head he is a genius or a god, to all the other eyes he is just another person. Humanity as a whole has a subjective conscounse, and we cannot step outside of our egocentric exhistence to really look at ourselves for what we are. "

So, wow, just had to rant. Some people gotta cry, I can't. I'm like Chuck muthafuckin Norris. I NEVER cry.
