Biography

Aldo Leopold was an American forester and conservationist who pioneered the land ethic—a revolutionary framework expanding moral consideration to soil, water, plants, and animals. His masterwork A Sand County Almanac transformed environmental philosophy by arguing that humans are part of nature's community, not its conquerors, profoundly influencing modern ecology and conservation movements.
