Everything you need to understand or teach Fen, Bog and Swamp by Annie Proulx.
Annie Proulx's Fen, Bog and Swamp is a work of environmental non-fiction that employs first, second and third person points of view in a series of short essays. The book opens with an essay that tangentially explores the underlying causes of the destruction of wetland ecosystems, and continues into three essays that detail the history of the distinct wetland ecosystems designations of "fen," "bog," and "swamp." Exploring themes of environmental destruction and conservation, human relationships to nature, agricultural history, and the spiritual significance of place, Proulx makes a compelling case for the protection of these critically endangered ecosystems.
