The question is, with today’s life expectancy of 78 years, what kind of return on investment is this over and above than the sheer beauty of clean air!

Clean Air

The study lead by Arden Pope, an epidemiologist at Brigham Young University in Utah, found that life expectancy had increased by 2.72 years between 1980 and 2000. Fifteen percent of this increase could be attributed to air quality, giving the reported 21 weeks. The reduction in smoking and general increase in socioeconomic conditions were the two most significant factors improving life expectancy.
