Unfortunately for us, the geologists, analysts, mathematicians, and former oil-company employees have all repeatedly come up with proof that our oil supply will be almost gone by the end of the 21st century, and that oil production will peak within a few years from now, if it hasn't already sone so.
After it peaks the oil will then become more expensive to extract than to use. And immediately after that, prices will soar, businesses will shut down, people will panic like animals, economies will collapse, wars will break out, blood will soak the ground, and billions of people will die horrible deaths as our species shrinks back to the population of the 1700s, or even that of Medieval times.
All because of that cursed, smelly brown muck that was once found oozing from the round.
Oi chief, oil at 12 o'clock. We may have trouble slamming these birds.
