Land ethic

A land ethic is a philosophy or theoretical framework about how, ethically, humans should regard the land. The term was coined by Aldo Leopold (1887–1948) in his A Sand County Almanac (1949), a classic text of the environmental movement. There he argues that there is a critical need for a "new ethic," an "ethic dealing with human's relation to land and to the animals and plants which grow upon it". Leopold offers an ecologically-based land ethic that rejects strictly human-centered views of the environment and focuses on the preservation of healthy, self-renewing ecosystems. A Sand County Almanac was the first systematic presentation of a holistic or ecocentric approach to the environment. Although Leopold is credited with coining the term "land ethic," there are many philosophical theories that speak to how humans should treat the land. Some of the most prominent land ethics include those rooted in economics, utilitarianism, libertarianism, egalitarianism, and ecology.

This is a land ethic based wholly upon economic self-interest. Leopold sees two flaws in this type of ethic. First, he argues that most members of an ecosystem have no economic worth. For this reason, such an ethic can ignore or even eliminate these members when they are actually necessary for the health of the biotic community of the land. And second, it tends to relegate conservation necessary for healthy ecosystems to the Government and these tasks are too large and dispersed to be adequately addressed by such an institution. This ties directly into the context within which Leopold wrote Sand County Almanac.

For example, when the US Forest Service was founded by Gifford Pinchot, the prevailing ethos was economic and utilitarian. Leopold argued for an ecological approach, becoming one of the first to popularize this term created by Henry Chandler Cowles of the University of Chicago during his early 1900s research at the Indiana Dunes. Conservation became the preferred term for the more anthropocentric model of resource management, while the writing of Leopold and his inspiration, John Muir, led to the development of environmentalism.
