Oil

About oil. A lot people say a lot of things, so I'll keep this brief. Robert Heinlein wrote this, probably at least four decades ago.

Ultimately, oil and dependence on it are a self solving problem. It's being consumed faster than it is being created, which means that eventually the imbalances in the world economy and ecology due to oil consumption will end. (Of course, if we prepared for this event we could make the transition to an oil free future a lot less painful than it is going to be, but conscientiously preparing for the future as a group just isn't done by the human race.)
