Having a lot of carbon around gives you a reducing environment (consumes oxygen). The world definitely has both carbon and oxygen.

One thing I do know. Clever wordsmithing does not equal science. It may be rhetoric, it may be poetry, but it does not equal science. Science would care about everything, not just a narrow line of narrative.

I am not at all well-informed on atmospheric chemistry and physics. I hardly know enough to ask a good question.

It seems to me, though, that we have so *little* carbon in our atmosphere (CO₂ is 400 ppm, which is only 0.04% --- compared to O₂, which is 21% or thereabouts.) It's hard for me to see how that little carbon dioxide effectively keeps enough plant biomass alive to keep up our rather astounding oxygen levels.

Does that make sense?
