Aldo Leopold (January 11, 1887 – April 21, 1948) was an American author, scientist, ecologist, forester, and environmentalist. He was a professor at theUniversity of Wisconsin and is best known for his book A Sand County Almanac(1949), which has sold more than two million copies.
Leopold was influential in the development of modern environmental ethics and in the movement for wilderness conservation. His ethics of nature and wildlife preservation had a profound impact on the environmental movement, with his ecocentric or holistic ethics regarding land.[1] He emphasized biodiversity and ecology and was a founder of the science of wildlife management.[2]
“The land ethic simply enlarges the boundaries of the community to include soils, waters, plants, and animals, or collectively: the land…[A] land ethic changes the role of Homo sapiens from conqueror of the land-community to plain member and citizen of it. It implies respect for his fellow-members, and also respect for the community as such.”
