For much of human evolution, the natural world was one of the most important contexts of children’s maturation. Indeed, the experience of nature was, and still may be, a critical component of human physical, emotional, intellectual, and even moral development. Yet scientific knowledge of the significance of nature during the different stages of childhood is sparse. This book provides scientific investigations and thought-provoking essays on children and nature. This work incorporates research from cognitive science, developmental psychology, ecology, education, environmental studies, evolutionary psychology, political science, primatology, psychiatry, and social psychology. The authors examine the evolutionary significance of nature during childhood; the formation of children’s conceptions, values, and sympathies toward the natural world; how contact with nature affects children’s physical and mental development; and the educational and political consequences of the weakened childhood experience of nature in modern society.
