Save The Trees, Save Yourself

Mat McDermott runs down the benefits of urban foliage:

After looking at trees in Atlanta, Baltimore, Boston, Chicago, Los Angeles, Minneapolis, New York City, Philadelphia, San Francisco, and Syracuse, [scientists at the Davey Institute and the U.S. Forest Service] found the annual removal of fine particulate matter varied from 4.7 metric tons in Syracuse to 64.5 metric tons in Atlanta. This correlates to one person’s life per 365,000 people saved each year in Atlanta, to one life saved for every 1.35 million people in San Francisco. Fine particulate air pollution can cause (in addition to premature death): Inflammation of the lungs, accelerate hardening of the arteries, and altered heart function.
