Trees are more than just beautiful fixtures of any city neighborhood. They make hot summer days more bearable by providing shade and naturally cooling air temperatures in the immediate surroundings. However, researchers have found a distinct and historical connection between tree canopy disparity in wealthy, mostly white neighborhoods and low-income, often minority communities.
