For anyone interested in wildlife, birds, wilderness areas, parks, ecology, conservation, environmental literature, and ethics, the name Aldo Leopold is sure to pop up. Since first publication, Aldo Leopold: A Fierce Green Fire has remained the classic short, inspiring biography of Leopold--the perfect companion to reading his ever popular A Sand County Almanac. Winning numerous awards, this comprehensive account of his life story is dynamic and readable, written in the context of the history of American conservation and illustrated with historic photographs. Marybeth Lorbiecki has now enriched A Fierce Green Fire in a way no other biography on Leopold has, adding numerous chapters on the ripple effects of his ideas, books, ecological vision, land ethic, and Shack, as well as of the ecological contributions of his children, graduate students, contemporary scholars, and organizations--and the wilderness lands he helped preserve. Lorbiecki weaves these stories and factual information into the biography in a compelling way that keeps both lay and academic readers engaged. In the introduction to this edition, Lorbiecki makes it clear how much better our lives are because Leopold lived and why today we so radically need what he left us to bring about paradigm shifts in our ethical, economic, and cultural thinking. Instead of losing relevance, Leopold's legacy has gained ever more necessity and traction in the face of contemporary national and world challenges, such as species loss and climate change. Even the phenological studies he started at as a hobby are proving valuable, showing the climatic shifts that have occurred at the Shack lands since the 1930s, recognized by the plants and animals.
