Fossil Fuels? Huh?
The correct scientific term includes a reference to Petrochemicals.
Hydrocarbons. Necessary for most of modern life. I support the abiotic theory, that hyrdo -- water -- and carbon -- mineral -- combine under pressure, making the process wholly natural.
The only fossils I consider worth getting to "zero" are the politicians, old, white rich activists spouting the Mathusian line, and all the old fossil academics whose "assumptive close" -- a sales pitch technique -- is to step past the very basic discussions in favor of blather and more blather.
