As made mad animals, we still have more than enough oil left, plus coal and gas, to power our necessary complete destruction our home ecosphere, to poison life everywhere with industrial by-products and plastic-chemical trash, deplete the last ground water systems, kill all remaining forests, and deplete all remaining arable soils. With these fossil fuel left-overs we can create enough deadly weapons to use in one more global war, before going lights out with a sad wimper.
