Poor air quality has led to an explosion of a health problems among vulnerable populations, claims the American Society of Landscape Architects. This video explains how urban forests provide environmental benefits to densely populated cities.
ASLA explains the "tremendous benefits" of urban forests:
"Urban forests reduce energy use by providing shade in the summer and wind breaks in the winter, reduce stormwater runoff, remediate soils, and provide animal and plant habitat."
Studies have shown that "...trees can reduce hourly ozone by up to 15 percent, sulfur dioxide by 14 percent, and particulate matter by 13 percent. U.S. trees remove some 784,000 tons of pollution annually, providing $3.8 billion in value."
