In the first broad-scale estimate of air pollution removal by trees nationwide, U.S. Forest Service scientists and collaborators calculated that trees are saving more than 850 human lives a year and preventing 670,000 incidences of acute respiratory symptoms. Researchers valued the human health effects of the reduced air pollution at nearly $7 billion every year. 

Studies have proven the environmental gains that come with infill development of brownfield sites. But there has not been reliable data on the actual value of brownfield remediation nationwide - until now. And the data is compelling.

Imagine if our cities were more like forests. Connected by green pathways for safe movement. Cooled with shade and evapotranspiration. Naturally absorptive of rainfall, turning this resource into drinking water and clean rivers. Protected from storms by the bend of trees and the natural sponge effect of marshes.
