In spring of 2004, when US gas prices hit US $2 a gallon, University of Washington senior Jo Blue kept on driving. After Hurricane Katrina last August, prices topped US $3 a gallon. But Blue kept driving. Now, when prices have leveled -at about US$ 2.25, she still commutes an hour everyday to her job as a swim coach. Blue has to get to work and public transportation is not an option. Buses to the suburb where she works are infrequent, so Blue has no choice but to spend US $30 a week on gas.

　　High gas prices, which began to soar in 2004, have Americans-whose way of life depends on cars-complaining, but not doing much to change the country's car culture.

　　Like Blue, most Americans, except those in major cities, drive to work. Many live in sprawling suburbs which are accessible only by car. The average American spends 55 minutes each day behind the wheel, according to the US Department of Transportation. In 2003, the US's 290, 000 residents registered 237, 000 vehicles.

　　Many experts say that this car driven lifestyle is unsustainable. "An event like Hurricane Katrina demonstrates how constrained and fragile the energy supply is now," said Barry Silverthorne, producer of "The End of Suburbia", a documentary about American car culture.

　　In the 1950s, King Hubert, a geologist working for Shell, a major US oil company, predicted that the rate of oil extraction(提取)could not continue to increase forever. Once all the high quality or easiest-to-reach oil was extracted, oil would become progressively scarcer and more expensive until the supply runs out altogether.

　　Many major oil fields in the Middle East have reached or will soon reach their peaks, says Megan Qinn, director of the Community Solution, an organization that promotes sustainable development.

　　Though most experts agree the US should become less dependent on cars, few have addressed the issue of "how".

　　"Deep down in America many of us have a sense that we are about to hit a brick wall of some kinD. But people are too distracted by Paris Hiton and iPods to notice," said Silverthorne.
