 We fight wars all over. This is from the last chapter, Chapter 6, titled Staving Off Extinction. We fight wars all over the world for oil, and we don't even need it. That in and of itself is insane. But when you look at a 250-million-year-old piece of sedimentary rock and see that it's virtually barren of fossilized life forms, you realize that this is a hell of a lot more important than whether or not our country is going to fight stupid wars and far-off lands so the oil companies and the Koch brothers can continue to get rich.
