Aldo Leopold (January 11, 1887 – April 21, 1948) was an American ecologist, forester, and environmentalist. He was influential in the development of modern environmental ethics and in the movement for wilderness conservation. Leopold is considered to be the father of wildlife management in the United States and was a life-long fisherman and hunter. Leopold died in 1948 from a heart attack two hours after fighting a brush fire on a neighbor's farm.[1]
[edit] Life and workIn 1933 he was appointed Professor of Game Management in the Agricultural Economics Department at the University of Wisconsin–Madison. He lived in a modest two-story home close to the campus with his wife and children, and he taught at the university until his death. Today, his home is an official landmark of the city of Madison. One of his sons, Luna, went on to become a noted hydrologist and geology professor at UC Berkeley. Another son, A. Starker Leopold, was a noted wildlife biologist and also a professor at UC Berkeley.[2] A third son, A. Carl Leopold, became a noted plant physiologist. [3] His nature writing is notable for its simple directness. His portrayals of various natural environments through which he had moved, or had known for many years, displayed impressive intimacy with what exists and happens in nature. Leopold offered frank criticism of the harm he believed was frequently done to natural systems (such as land) out of a sense of a culture or society's sovereign ownership over the land base – eclipsing any sense of a community of life to which humans belong. He felt the security and prosperity resulting from "mechanization" now gives people the time to reflect on the preciousness of nature and to learn more about what happens there. However, he also writes "Theoretically, the mechanization of farming ought to cut the farmer's chains, but whether it really does is debatable." [4] [edit] A Sand County AlmanacThe book was published in 1949, shortly after Leopold's death. One of the well-known quotes from the book which clarifies his land ethic is
The concept of a trophic cascade is put forth in the chapter "Thinking Like a Mountain", wherein Leopold realizes that killing a predator wolf carries serious implications for the rest of the ecosystem.[5]
[edit] ConservationIn "The Land Ethic", a chapter of A Sand County Almanac, Leopold delves into conservation in "The Ecological Conscience" section. He wrote: "Conservation is a state of harmony between men and land." According to him, curriculum-content guidelines in the late 1940s, when he wrote boiled down to: "obey the law, vote right, join some organizations and practice what conservation is profitable on your own land; the government will do the rest."(p.243-244) [edit] DigitizationCurrently the Digital Content Group of University of Wisconsin–Madison is conducting a large-scale digitization of Aldo Leopold's journals and records. They are expected to be made available online late 2009.[7] [edit] See also
