brians356 said:Petroleum is "natural", it's just dead organisms. "Natural" is one of the most misused terms in common usage. Petroleum is a naturally occurring liquid found in geological formations when large quantities of dead organisms, usually zooplankton and algae, are buried underneath sedimentary rock and subjected to intense heat and pressure. What's "unnatural" about it?
I think the implied context is you wouldn't want to add the all natural unsaturated benzo-rings as a salad dressing. Plus with my luck the required distal level probably requires Saudi oil like diesel gas. That said, 10 cans of imperial will probably last me the remainder of my life.
