In July 2011, Rebecca Prince-Ruiz challenged herself to go plastic free for the whole month. Starting with a small group of people in Perth, the Plastic Free July movement has grown into a 250-million strong community across 177 countries, empowering people to reduce single-use plastic consumption and create a cleaner future. This book explores how one of the world's leading environmental campaigns took off and shares lessons from its success. From narrating marine-debris research expeditions to tracking what actually happens to our waste to sharing insights from behavioral research, it speaks to the massive scale of the plastic waste problem and how it can be tackled. Interweaving interviews from participants, activists, and experts, Plastic Free tells the inspiring story of how ordinary people have created change in their homes, communities, workplaces, schools, businesses, and beyond.
