Since his death in 1948, Aldo Leopold has been increasingly recognized as one of the indispensable figures of American environmentalism. A pioneering forester, sportsman, wildlife manager, and ecologist, he was also a gifted writer whose farsighted land ethic is proving increasingly relevant in our own time. Now, Leopold's essential contributions to our literature--some hard-to-find or previously unpublished--are gathered in a single volume for the first time. Here is his classicASand County Almanac, hailed--with Thoreau'sWaldenand Carson'sSilent Spring--as one of the main literary influences on the modern environmental movement. Published in 1949, it is still astonishing today: a vivid, firsthand, philosophical tour de force. Along withSandCountyare more than fifty articles, essays, and lectures exploring the new complexities of ecological science and what we would now call environmental ethics. Leopold's sharp-eyed, often humorous journals are illustrated here for the first time with his original photographs, drawings, and maps. Also unique to this collection is a selection of over 100 letters, most of them never before published, tracing his personal and professional evolution and his efforts to foster in others the love and sense of responsibility he felt for the land.
