As the Obama administration considers further steps to fight air pollution, a recent report from a Washington think tank shows that air quality in the United States has improved significantly over the last decade.
The American Enterprise Institute for Public Policy Research analyzed data collected by the U.S. Environmental Protection Agency and concluded that levels of numerous gases linked with air pollution have fallen off since 2001.
Among the findings: Carbon monoxide decreased by 39 percent, ozone by 6 percent, and sulfur dioxide by 32 percent.
"Pick any category you want and pollution levels are generally lower than they were seven years ago," said Steven Hayward, the policy analyst who authored the report, titled "Index of Leading Environmental Indicators," for the conservative think tank.
"(Environmental groups) said air pollution was out of control, but this was always more about politics than it was fact," Hayward said. - FOX News Story
