Urban street trees slow traffic, provide sidewalk shade, improve air quality, and reduce the urban heat island effect - contributing to improved health outcomes for children, older adults, and those living in poverty. Air quality vulnerability varies between neighborhoods - and so does the presence of trees - but new trees are rarely planted with this in mind.
