A recent article published by ZMEScience describes the usefulness of trees as a solution to urban pollution. Beyond the aesthetic beauty that tree-lined streets provide, researchers are finding that trees remove air pollutants caused by car exhaust, road dust and dust particulates from the air we breathe.
Researchers at Lancaster University in England measured particulates both inside and outside of homes on an urban street with no trees. They then lined the street with silver birch trees, re-measured the particulate levels, and discovered the quantity of polluting particulates was reduced by 50 percent.
Locally, the 2013 iTree report showed that along with reducing particulate matter, trees in the Kansas City region remove about 1 million tons of carbon from the atmosphere each year and reduce residential energy costs.
