    I tend to agree with you. Earth has always been in a constant state of change. We seem to have this perception that Earth's current state is optimal and that any change is bad. Certainly change could bring adverse effects but the premise that we're "ruining the planet" is too easily accepted. If we were living during the last ice age and having this discussion, our descendants in the common era would be having a laugh.

Responsible scientists are more likely to point out that we are doing the largest uncontrolled experiment in history on the Earth's climate system, and perhaps we should pay attention to what we're doing. Earth has always been in a state of change, yes, but we are currently in the midst of the fastest change, at least within the past few million years, possibly longer.
