Uh might want to reconsider that one there...
99.9% of fossil fuel is derived from plant matter,
maybe you’ve noticed something similar when you are
out hunting in the woods and sometimes you never see
a single deer.
Not even close to the mass balance.
Convertible organic mass diminishes to almost zero among plants.
A corresponding 90 ton tree would decay into about 1-2 pounds of convertible organic debris.
The overall point is that ‘fossil fuel’ is a misnomer.
It was really “coined” when the oil producing formations were found in fossil-containing strata.
Abiotic crude is more correctly used for the material we refine into fuels.
