I prefer the term petroleum instead of fossil fuels. I really really doubt that all of the fuel we're burning came from the decomposition of biomass. It just doesn't make sense to me. Especially how such biomass got to be a thousand or so feet underground. Hydrocarbons seem to be produced by the planet. Maybe biomass can be converted into oil in a natural way. What I don't believe is that most of the petroleum on the planet came from it.

I just wish humanity would use more varied fuels that don't create nasty fumes. Human power for local transportation needs to expand a little more. Instead the bellies of humans are expanding.
