This textbook introduces the reader to the new and emerging field of Conservation Psychology, which explores connections between the study of human behavior and the achievement of conservation goals.People are often cast as villains in the story of environmental degradation, seen primarily as a threat to healthy ecosystems and an obstacle to conservation. But humans are inseparable from natural ecosystems. Understanding how people think about, experience, and interact with nature is crucial for promoting environmental sustainability as well as human well-being.The book first summarizes theory and research on human cognitive, emotional, and behavioral responses to nature and goes on to review research on people's experience of nature in wild, managed, and urban settings. Finally, it examines ways to encourage conservation-oriented behavior at both individual and societal levels. Throughout, the authors integrate a wide body of published literature to demonstrate how and why psychology is relevant to promoting a more sustainable relationship between humans and nature.
