also.. something else to keep in mind.. volcano eruptions (a purely natural occurance) have alone done more 'damage' to the atmosphere and the environment than we have, or ever WILL, in our entire existence of species.
and theyre going to keep erupting. because everything is a cycle. the earth wasnt made to last forever. species have been going extinct now since the beginning of time, and new species fill the niches as they go. (you hear about all the extinctions... try looking up how often they find new species, you'll see there is a WHOLE lot more of that going on than the media lets on to.

)
are we damaging the environment? yes. are we really that big of a contributor to the detriment of the environment vs. the natural evolution of the earth as has been going on since LONG before our technologies allowed us to? absolutely not.
be green. recycle. its good for the earth, and its not wasteful (which is always a good thing). but nobody will ever prove to me that we are the ones 'ruining' the world.
people just don't like change, and the world is changing.
