Urgent environmental problems call for vigorous research and theory on how humans develop a relationship with nature. For eight years, Peter Kahn studied children, young adults, and parents in diverse geographical locations, ranging from an economically impoverished black community in Houston to a remote village in the Brazilian Amazon. In these studies Kahn sought answers to the following questions: How do people value nature, and how do they reason morally about environmental degradation? Do children have a deep connection to the (...) natural world that gets severed by modern society? Or do such connections emerge, if at all, later in life, with increased cognitive and moral maturity? Are there universal features in the human relationship with nature? Kahn's empirical and theoretical findings draw on current work in psychology, biology, environmental behavior, education, policy, and moral development. (shrink)
