Book excerpt: This book will teach you everything you need to know about sustainable living—from reducing your greenhouse gas footprint to making sure that you are part of the green economy. Along the way, readers will learn about the field of sustainability and the “three E’s” of sustainable living—environment, economy, and equity. We are in the midst of great environmental change and all of us need to do everything we can to try to live more gently on the planet. Robert Brinkmann provides a range of options for readers as to what they can do to try to make a difference. Some involve simple lifestyle changes - but he also challenges all of us to commit to make more difficult and more meaningful changes to create a greener, more sustainable world. The book also delves into how we can create more sustainable communities, schools, and organizations. It showcases many examples of people and organizations that are making significant contributions to improving our planet’s sustainability that serve as inspiration and guidance for all of us trying to live more sustainably.
