Alarmed by drastic changes in the Earth's climate systems, the author, a climate scientist and suburban father of two, embarked on a journey to change his life and the world. He began by bicycling, growing food, meditating, and making other simple, fulfilling changes. Ultimately, he slashed his climate impact to under a tenth of the US average and became happier in the process. Being the change explores the connections between our individual daily actions and our collective predicament. It merges science, spirituality, and practical action to develop a satisfying and appropriate response to global warming.
