First off when you are talking about potentially wiping out certain species or killing off reefs that have taken 1000's of years to form in "a days work" then I think it is pretty hard to say that we are looking at things on too short of a time frame. Secondly you are comparing a natural disaster to a man made oil spill....what? third, I am pretty certain people do scream bloody murder when a volcano erupts. Not to mention, sitting back and saying well, it's OK, we can do whatever we want cause theoretically the world should "right it" in around 5000 years is crazy. I live here now.
