nature deficit disorder
n.— «The increased activism has been partly inspired by a best-selling book, “Last Child in the Woods,” and its author, Richard Louv. Coining the term “nature deficit disorder,” Louv has argued that indoor kids are more prone to a range of childhood problems, including obesity, depression and attention disorders. He contends that they miss out on the spiritual, emotional and psychological benefits of exposure to the wonders of nature, including reduced stress and improved cognitive development, creativity and cooperative play.» —“Getting Lost in the Great Indoors” by Donna St. George Washington Post June 18, 2007.
