War for oil - Mission accomplished.
Dig it out of the ground. Pump it into a tanker. Ship it half way around the planet. Put the enviornment in jeapordy. Place it in a truck. Pump it back into the ground. Pump in out of the ground and into your car. Drive it around as it sloshes around in the tank of your car. Burn it in your engine. Spit it out your exhaust pipe. Evaporate it into the atmosphere. Eat up all the oxygen in the air. Start more wars to ensure supplies. Spend billions and billions and billions. Kill millions. Cause global warming. Spend trillions cleaning up the mess.
OR. Drive with Biodiesel. Which makes more sense to you?
