Given the media coverage surrounding climate change, most people are aware of this environmental issue. One that is less well known but may become just as crucial is "peak oil." What is peak oil? Simply put, it is the point at which the world production of oil reaches its highest point and begins a steady, irreversible decline. This has been known for some time. Hubbert's Curve (1956), named for the scientist who formulated it, predicted that U.S. production would peak around 1970. He was off by 1 year. Since 1971-2, the oil production of the United States has been gradually declining. -To argue that climate change presents a serious danger -To persuade readers to take action on the issue of peak oil -To introduce the subject matter by comparing it to a familiar issue -To provide a definition of the term "peak oil"
