With the eye of a professional scientist and the passion of a dedicated amateur, E. C. Pielou conducts a guided tour of fresh water on its course through the natural world. As the world's supply of clean, fresh water continues to dwindle, it becomes increasingly important to understand the close connection between water and all forms of life. Pielou's fascination with fresh water gives us a "natural history" that is remarkable and surprising. "[A] keen and detailed look at the life and history of fresh water. . . . Dip into Fresh Water. It will both stimulate and satisfy as only good natural history can."--Toronto Globe and Mail "Pielou's ease with her subject and her no-nonsense style of writing will satisfy and inspire the poet as well as the naturalist."--Denize Springer, Express Books "[Pielou's] writing is didactic and definitive, in places even charming, and is buttressed by clear illustrations. . . . A welcome addition to the genre of literature designed to bridge the gap between scientists . . . and the intelligent and concerned lay public."--Daniel Hillel, Nature "A wonderful natural history of one of life's necessities, a refreshing break from the grand theory and special pleading of many a science book. . . . Read it."--Fred Pearce, New Scientist Aucune description trouvée dans une bibliothèque |

Acute observation and a fluid writing style characterize this detailed, but not overly technical description of the hydrological cycle. An attractive aspect of Pielou's presentation is her encouragement to the reader to copy her observational techniques, for example, wading into a stream to measure its flow and carefully watching the water in order to understand a landscape's shape. Her chapters correspond to where fresh water accumulates: underground, in streams and rivers, in wetlands, in lakes natural and artificial, and in clouds. She explains particularly well water's unusual chemical properties--its surface tension as a liquid, its expansion as a solid--that influence the depth of the water table, or how a lake freezes. Numerous line drawings help readers understand particular hydraulic situations; the text's calmness elicits concern for how civilization uses this limited resource, whether drilling for it or damming it up. A rare resource itself, Pielou's soft-sell presentation will probably sensitize more people to the cause of water conservation than hectoring tracts from environmental advocacy groups..
