"For that, IMO, it makes no difference if it's biotic or abiotic."
For an abiotic continuous process, if not for the human consuming it just as it bubbled from the earths crust, what would our destiny be? Swimming in it?
With that, for whatever you consider to be the process....the way we utilize it, is detrimental to living biotic nature.
If you do not believe that, experimentally I can put you to sleep forever in less than 45 minutes utilizing the process we now worship.
The way it looks, if an abiotic process is perpetual we die if not consumed.
As far as I know, the earth does not have a chimney, so we die if we consume.
