Do you attribute 'special' status to humans?
Isn't there something about the atmosphere used to be majorly CO2 based, and it caused a crap load of sea algae to bloom to the point where they consumed so much CO2 and produced so much O2 that it flipped the atmosphere to be more oxygen based? The point is, if you were an outside observer watching earth, would you really say what humans are doing is unnatural, abnormal? All animals if given an environment in which they can flourish will consume all the resources until they're all gone, why do you think we're any different? Are you religious?
Not religious at all. I understand what you are saying but I do think that humans operate at a significantly higher level than the other species on Earth. We have a greater awareness of our actions and, as such, should probably have a greater responsibility over them when they affect the place we call home (Earth).
Unfortunately, what is happening is that people are becoming ever more isolationist within themselves and their immediate tribe (family/friends) to the point that nothing else matters outside of that sphere and so its largely ignored
