Natural gas drilling rigs scrape the sky in Garfield County, Colo., Saturday, Jan. 15, 2011. More than 400 methane wells have leaked an estimated 30 tons of carcinogenic benzene into the area environment. Pollution regulations are lighter for the gas industry where emissions are considered an isolated case. But in areas of high well density the emissions amount to more than for an oil refinery in an urban area. (Kevin Moloney for the New York Times)
