Air Pollution's Wake Of Destruction

Air pollution from Maryland's six largest coal-fired power plants causes an estimated 700 premature deaths a year and about 30,000 astham attacks annually, according to a study by the Harvard School of Public Health.

The report is part of a campaign with environmental groups to pass stronger air pollution laws in Maryland, according to the Baltimore Sun. Jonathan Levy, an Assistant Professor of Environmental Health at Harvard, said that air pollution in Maryland had been improving through 2003, but got worse in 2004 and 2005.
