From USA Today:
Wyoming’s smog exceeds Los Angeles’ due to gas drilling
Rural Wyoming, known for breathtaking vistas, now has worse smog than Los Angeles because of its boom in natural gas drilling.
Residents who live near the gas fields in the state’s western corner are complaining of watery eyes, shortness of breath and bloody noses, reports the Associated Press. The cause is clearer than the air: local ozone levels recently exceeded the highest levels recorded in the biggest U.S. cities last year.
