nature-deficit disorder
n.— «The real disorder lies in the society that has disengaged children from nature and imposed on them an artificial environment for which they have not evolved. Viewed from this angle, children and adults alike would suffer from what might be called nature deficit disorder, not in a clinical sense, but as a condition caused by the cumulative human costs of alienation from nature, including diminished use of the senses, attention difficulties, and higher rates of physical and emotional illnesses.» —“Robert Bateman Launches Environmental Awareness Program” in Vancouver, Canada CNW Group Mar. 1, 2007.
