Your mis-characterizing what I'm saying.
I'm saying human activity is naturally occurring, this is because of the fact, that humans are a natural part of the ecosystem. We are not some aliens from another planet, we are not some disease form outer space. Believe it or not, this planet created us and our abilities to manipulate the environment. Probably ever creature on this Planet manipulates their environment in some way or another. To single out humans and say because we are smarter then the other animals and therefore our impact of the environment is bad, is wrong.
You can have a red tide that wipes out huge numbers of fish, but that is natural. You can have Beatles that decimate a forest, but that is natural. You can have a pathogen that wipes out the bee population, but that is natural. But us humans, disturb one rock, "Oh, better put that back where it belongs".
Sure, us humans have a brain and maybe we can stumble our way into doing something half right, but it does not mean we need to have a environment that is untouched by us "naturally" occurring humans. For if we don't evolve the way nature intends us too, then what happens will be unnatural.
I mean, when did humans become "unnatural", when we started to walk upright, when we learned how to use sticks and stones, or was it when we harnessed fire. Are the only people that are allowed to have a green card, are those that live under a rock. :lol:
