As trees disappear from urban neighborhoods, lives may be lost with them. In a new study, Northwestern University scientists tracked death rates and fluctuations in tree canopy cover across an 11-year period in Chicago. They found that areas experiencing greater losses in tree canopy—land covered by trees' leafy crowns—also experienced higher mortality rates, particularly in the city's hottest neighborhoods.
