Integrated studies of tree effects on air pollution reveal that management of urban tree canopy cover could be a viable strategy to improve air quality and help meet clean air standards. A modeling study using hourly meteorological and pollution concentration data from across the coterminous United States demonstrates that urban trees remove large amounts of air pollution that consequently improve urban air quality.
Higher street tree density was associated with a lower prevalence of childhood asthma even after adjustment for potential confounders (including sociodemographic characteristics, population density and proximity to pollution sources.
Among preschool children from low-income families, neighborhood homicide rate was associated with more obesity and street tree density was associated with less obesity.
A flier, journal article, and presentation about reports suggesting “greener” surroundings have influence on lower fear levels, fewer incivilities, less violent behavior, and fewer reported crimes.
Higher levels of green vegetation are associated with decreased mortality. Policies to increase vegetation may provide opportunities for physical activity, reduce harmful exposures, increase social engagement, and improve mental health. While planting vegetation may mitigate effects of climate change, evidence of an association between vegetation and lower mortality rates suggests it also might be used to improve health.
