Louisville, Kentucky, has some of the worst air in the country. Given the city is a transit hub, tens of thousands of planes, trucks, and trains pass through the city each year, not to mention all the cars. Louisville is also an industrial center where chemicals are manufactured. Heart disease, strokes, asthma and other conditions caused by excessive pollution are found at very high levels. Last year, the city received a failing grade from the American Lung Association in its annual report.

In order to see if trees can help combat the negative health impacts of the city’s deadly air pollution, University of Louisville Medical Center, the Nature Conservancy, Hyphae Design Laboratory and other organizations are coming together in the Green Heart project, the first clinical trial where “nature is the pharmaceutical.”
