"If the eco of ecology has literary cornerstones, they are Thoreau's 'Walden,' Marsh's 'Man and Nature,' Carson's 'Silent Spring,' and Leopold's 'A Sand County Almanac.'"-Sierra Club Magazine "The power of 'A Sand County Almanac' is that it helps us see in so many ways that the land is an organism, a circulating system, of which we are but a part. If and when we tinker, we must exercise ultimate care." -Woodnotes Published the year after Aldo Leopold died, A Sand County Almanac, a literary landmark in conservation, which blends poetic prose with keen observations of the natural world, was the naturalist's most influential work. Having been translated into nine languages, it has sold millions of copies worldwide and is considered to be a cornerstone for modern conservation science, policy, and ethics. This classic program, narrated by Lorne Greene (Bonanza), is based on the ecologist's famous book and includes his personal collection of beautiful nature sketches and philosophical essays on ecology and ethics.
