A new study suggests that an increase in average life expectancy of five months is the result of decreases in air pollution between 1980 and 2000.
Researchers at Brigham Young University and Harvard School of Public Health have released a study suggesting that a reduction in air pollutants in 51 U.S. cities between 1980 and 2000 has added an average of five months to life expectancy. Moreover, residents in cities that made the most significant improvements in air quality, such as Pittsburgh, PA, can expect to live almost 10 months longer.
