Divided into three sections, Hope, Human and Wild profiles the efforts of three caring communities to preserve wilderness and reverse environmental devastation. They include the reforestation of McKibben's home territory, New York's Adirondack Mountains; solving traffic and pollution problems in the densely populated Curitiba, Brazil; and how the citizens of Kerala, India have demonstrated that quality of life doesn't depend on overconsumption of resources. This edition features a new introduction that revisits these places and explores how they've changed over the years.
