Aldo Leopold [photo]
English
Aldo Leopold (1887-1948), (left, with naturalist Olaus Murie) was an American ecologist famous for the ‘land ethic’ he proposed in his book A Sand County Almanac (1949). Leopold believed we must change our characters from “conqueror of the land-community” to “plain member and citizen of it”; only then will we respect all creatures of the natural world as our “fellow members” in a shared community.[fn][[nid:684]][/fn]
