My brother in Christ, you literally have no idea how much stuff is made out of petrochemicals, do you? Try asphalt, industrial solvents, cosmetics, any real lubricant, fertilizers, pesticides, textiles, circuitry, detergents, insulation, PVC, paint, adhesives, roofing material, synthetic rubbers, as well as a ton of pharmaceutical products and food additives. And that’s not even an exhaustive list. Gasoline is a big part of the petrochemical industry, but it’s not the totality of it.
