From Pulitzer Prize winner Annie Proulx—whose novels are infused with her knowledge and deep concern for the earth—comes a riveting, revelatory history of our wetlands, their ecological role, and what their systematic destruction means for the planet. A lifelong environmentalist, Annie Proulx brings her wide-ranging research and scholarship to the subject of wetlands and the vitally important yet little understood role they play in preserving the environment—by storing the carbon emissions that greatly contribute to climate change. Fens, bogs, swamps, and marine estuaries are the earth’s most desirable and dependable resources, and in four stunning parts, Proulx documents the long-misunderstood role of these wetlands in saving the planet.
