“1997, for instance, the EPA moved to reduce surface ozone, a form of air pollution caused, in part, by emissions from oil refineries. Susan Dudley, an economist who became a top official at the Mercatus Center, came up with a novel criticism of the proposed rule. The EPA, she argued, had not taken into account that by blocking the sun, smog cut down on cases of skin cancer. She claimed that if pollution were controlled, it would cause up to eleven thousand additional cases of skin cancer each year.”
