Without the quote marks, I got 1000 doing it both ways. Maybe a temporary glitch?
BTW, some argue that oil has nothing (or not much) to do with dead dinosaurs and vegetation. Their idea is that oil is a chemical process from deep in the earth. That is called "abiotic oil".
Peak oil is still a problem, because we have used all the easily obtained stuff that has gotten near the surface.
Now, we have to drill miles below the surface. That is a problem source, as has happened off the coast of Louisiana in the Gulf.
Eventually, even that will be depleted, as we are extracting in a 100 years or so what took millions of years to generate.
And, eventually we will reach a point where it "costs" more than a barrel of oil to find, extract, transport, and refine a barrel of oil.
Too many people breeding too many litters of rugrats with no thought of consequence.
