They're all greater than the amount of gallons spilled by not extracting and transporting it in the first place and instead finding alternative sources of energy supply.
Yeah, that's just not true. With appropriate investment alternative energy technology today can replace all fossil energy sources. You just have to build the wind turbines and the solar panels, and the batteries, and the power-to-gas facilities. It's expensive to change the entire energy supply, but its doable.
I'll be honest, I'm not a material scientist. Do we make plastics and packaging and medical devices out of natural gas? Are we talking about petroleum at all in this discussion? Does this whattaboutist thing actually address the point I'm making at all?
