A SAND COUNTY ALMANAC

There are some who can live without wild things, and some who cannot,' begins Aldo Leopold's totemic work of ecological thought. Ranging from lyrical observations of the changing seasons over a year on his Wisconsin farm to his hugely influential idea of a 'land ethic' signifying moral equilibrium between humans and all other life on earth, A Sand County Almanac changed perceptions of the natural world and helped give birth to the modern conservation movement.
