A California Highway Patrol officer travels south with commuters on Interstate 5 as they make their way through heavy morning fog near San DiegoI have a confession to make — I’m glad gas prices in the United States, as elsewhere, are rising. And I’m quietly hoping they’ll keep going higher because there may possibly be no more effective way to promote conservation and reduce carbon dioxide emissions.
 
Higher pump prices might be the only way that we Americans will ever even begin adjusting our driving habits and reducing fuel consumption — when it hits you in the pocketbook. The price of gas in the United States may be cresting at over the $4 per gallon level but it is still far lower than it many other countries where fuel taxes are much higher.
