Climate change is the biggest threat of our century, one that will impact every aspect of children's lives: their physical, emotional, moral, financial, and social health and well-being. The relationship between the climate crisis and mental health in young people is therefore by definition multi-disciplinary and multi-cultural, requiring multiple perspectives on how to understand and guide younger generations. This book provides a unique synthesis of those perspectives - the science, psychology, and social forces that can be brought to bear on supporting young people's psychological well-being. No matter the setting in which an adult may interact with younger people, this book provides the intellectual rigor and tools to ensure those interactions are as helpful and supportive as they can be.
