In Imagine It!, the documentary filmmakers behind Fed Up, The Biggest Little Farm, The Social Dilemma, and the Academy Award-winning An Inconvenient Truth highlight the need to change some of our food, clothing, and transportation habits and meaningfully lower our use of plastic, paper, water, and harmful chemicals. They call the changes in these areas lifestyle or footprint shifts, and there is a chapter devoted to each one of them in the book. Each begins with a short story on the footprint being explored, and then provides clear steps for replacing old habits with new ones to create a more sustainable future.
