"LOS ANGELES -- Wildfire smoke poses a growing health risk to millions of Americans, even for those who live hundreds of miles from the flames, a new report by an environmental group says."
"About two-thirds of Americans, or nearly 212 million people, lived in counties that two years ago contended with wildfire smoke linked to respiratory problems such as asthma, pneumonia and chronic lung diseases, according to a report released by the Natural Resources Defense Council.
The group used satellite imagery of smoke plumes from the 2011 wildfire season - one of the worst in recent years - to take a nationwide snapshot of air quality. The analysis found that the extent of the country affected by wildfire smoke was 50 times greater than the area burned in the fires."
Tony Barboza reports for the Los Angeles Times October 26, 2013.
