Fens, bogs, swamps and marine estuaries are the earth’s most desirable and dependable resources, and in four illuminating parts Proulx documents the emergence of their systemic destruction in the pursuit of profit and the consequent release of their stored carbon. Wide-ranging and idiosyncratic, Proulx’s explanation of wetlands takes readers to the fens of sixteenth-century England, Canada’s Hudson Bay Lowlands, Russia’s Great Vasyugan Mire and America’s Okefenokee National Wildlife Refuge and introduces the nineteenth-century explorers who launched the ravaging of the Amazon rainforest.
