Book excerpt: "From foraging and hunting for food to (more recently) finding solace and peace in a beautiful vista, humans have long interacted with the natural world. Though a connection to nature runs deep in our DNA, however, people of the modern age are indoors almost 93% of the day. With that said, there is a growing evidence suggests that the natural world promotes mental and physical well-being, including stress relief, improved mood, and neurological benefits. Ecotherapy, a steadily developing but lesser-known construct in mental health, explores the reciprocal relationship humans have with nature and its capacity to build strength and provide healing. Nature Is Nurture provides an overview of the theoretical concepts and empirical bases of ecotherapy via historical considerations and recent research within the discipline. Chapters share practical ways to incorporate ecotherapy with children, adults, and veteran populations; within schools; and in group work. Descriptions of modalities such as animal-assisted, equine-assisted, horticultural, forest-bathing, green-exercise, and adventure-based therapy are also included alongside case examples, techniques, and practical and ethical considerations. In examining the impact of improved physical and mental wellness for all clients, this book provides counselors, therapists, social workers, and psychologists with the knowledge and techniques to infuse ecotherapy into everyday practice."
