There is no doubt about that. We cannot destroy the "planet". What we can do, and what we are doing, is damaging the atmosphere of the planet that sustains life, and as we do this it impacts every living breathing entity on the face of the earth. While we may not be able to destroy the "planet" we are damaging the thing layer of gases that provide the possibility of live on this chunk of rock.

I think life will continue on without us. There is speculation now, that the biomass in the earth's crust is larger than that found on the surface (micro-organisms living in cracks in the rocks). Life goes on, even after mass extinction events.
The Human species is fortunate to have survived as long as it has. A comet could have ended us any time. Unless the human race can colonize space, our extinction may be inevitable.
