By Robert Slater, author of Seizing Power: The Grab for Global Oil WealthThe BP ( BP) oil spill has deservedly captured the media's attention. It has been the dominant story in America all spring and summer. But to look at the wider picture, the spill is part of a much larger story -- the fact that oil, the world's most cherished resource, is running out. But few watching their television sets or listening to radios have learned of that larger picture during the Gulf oil spill. And that larger picture has far greater implications for the world. Naturally, television anchors focus on the nitty-gritty details: How many barrels of oil spilled into the Gulf this week? How quickly the spill will be stopped? Who is responsible? That is hardly surprising that the media focuses on today, not on what is perhaps going to happen in 100 to 150 years. Still, the BP oil spill, while its attendant loss of oil was tiny compared to the total amount of oil consumed yearly in the United States, is an unpleasant reminder that, because of the way we are consuming oil, there will be none left sometime in the next century or two.
