Easy there fuckwit. Your statement says you believe humanity is the worst thing for humanity when thats exactly what is being inferred in this discussion already. Humanity is effecting humanity environmentally as well as the obvious war, greed, murder, abuse, and such.
Humanity is actually the best thing to happen to humanity. If it weren't we would not be here. We have gained, and continue to gain, the knowledge to make things better for ourselves. What we are seeing is that we are in fact affecting our environment in big ways that are going to affect us in the long run. Were we ignorant and unable to to understand these things we would not have gotten very far in the evolutionary time line.
