If we're a disease, don't you want to exterminate us? But then, if all other life is so much better than human life, and if by adding 220ppm of CO2 we extended the time left for that life on Earth by a few million years, didn't our intervention save non-human life from a worse fate[0] than merely having to deal with us? So we can be both, disease and cure. [0] All life on Earth will go extinct eventually, but if we've added a few million years to its story so far, and we could add more millions later, then maybe saying we've "saved" that life is fair.
