Yep. I agree. Planet don't care if we survive or not. Planet will be here long after whatever we do to it, and long after the last cockroach croaks.
The planet can take whatever we or anything else throws at it. Until, a coupla billion years hence, it gets swallowed up by our sun's super nova. (I don't worry about that much. C'est la vie and all that.)
But, we do, I think, care for our own survival and quality of life upon the planet in the geologically brief period we remain upon it, so best to pay attention to threats is my counsel.
