Rebecca Prince-Ruiz set a goal to avoid using plastic entirely for the month of July 2011. The Plastic Free July movement, which got its start with a small group of Perth residents, has expanded to 177 countries and 250 million members, enabling people to use less single-use plastic and build a greener future. This book examines the launch of one of the most successful environmental initiatives in history and offers takeaways from its success. It illustrates the enormous scope of the plastic trash problem and how it may be solved by describing marine debris research cruises, tracking what actually happens to our waste, and offering insights from behavioural study. Plastic Free weaves together participant, activist, and expert interviews to present the amazing tale of how common people have built change in their homes, communities, workplaces, schools, businesses, and beyond.
