How the obese is partly responsible for global warming

And people wonder if this negative publicity is a bad thing:

Its authors, from the Centers for Disease Control and Prevention, did a sort of back-of-the-envelope calculation of how much extra fuel airlines spend hauling around fatter Americans. The answer, they wrote, based on the extra 10 pounds the average American gained in the 1990’s, is 350 million gallons, which means an extra 3.8 million tons of carbon dioxide.

“People are out scouring the landscape for things that make obese people look bad,” said Kelly Brownell, director of the Rudd Center for Food Policy and Obesity at Yale.

And is that a bad thing? Dr. Jacobson doesn’t think so. “We felt that beyond public health, being overweight has many other socioeconomic implications,” he said, which was why he was drawn to calculating the gasoline costs of added weight.

The idea of using economic incentives to help people shed pounds comes up in the periodic calls for taxes on junk food. Martin B. Schmidt, an economist at the College of William and Mary, suggests a tax on food bought at drive-through windows. Describing his theory in a recent Op-Ed article in The New York Times, Dr. Schmidt said people would expend more calories if they had to get out of their cars to pick up their food.
