How City Trees Support Human Health

The environmental services and benefits of urban trees are diverse and well recognized. Trees capture and store carbon, remove other air pollutants, decrease stormwater runoff and flooding, and keep our communities cool. What is less recognized is the relationship between urban trees and human health. The University of Washington, Natural Resources Canada, Health Canada, University of British Columbia, Toronto and Region Conservation Authority, and Tree Canada partnered to analyze 201 scientific studies from across North America, Europe and Asia. Results revealed more in-depth knowledge about the impacts of urban trees on human health.
