  3. Land Ethic What is a land ethic?

  4. Aldo Leopold 1887-1948 Land Ethic “When the private landowner is asked to perform some unprofitable act for the good of the community, he today assents only with outstretched palm. If the act costs him cash this is fair and proper, but when it costs only forethought, open-mindedness, or time, the issue is at least debatable.” The Shack - In 1935, he and his family initiated their own ecological restoration experiment on a worn-out farm along the Wisconsin River outside of Baraboo, Wisconsin.

  5. Aldo Leopold Continued Land Ethic Continued “To sum up: a system of conservation based solely on economic self-interest is hopelessly lopsided. It tends to ignore, and thus eventually to eliminate, many elements in the land community that lack commercial value, but that are (as far as we know) essential to its healthy functioning. It assumes, falsely, I think, that the economic parts of the biotic clock will function without the uneconomic parts. It tends to relegate to government many functions eventually too large, too complex, or too widely dispersed to be performed by government.”

  6. Aldo Leopold Continued Land Ethic Continued Aldo Leopold, A Sand County Almanac The land Ethic The land-relation is still strictly economic, entailing privileges but not obligations. All ethics so far evolved rest upon a single premise: that the individual is a member of a community of interdependent parts. His instincts prompt him to compete for his place in the community, but his ethics prompt him also to co-operate. The land ethic simply enlarges the boundaries of the community to include soils, waters, plants, and animals, or collectively: the land. We can be ethical only in relation to something we can see, feel, understand, love, or otherwise have faith in. The case for a land ethic would appear hopeless but for the minority which is in obvious revolt against these “modern” trends. Examine each question in terms of what is ethically and esthetically right, as well as what is economically expedient. A thing is right when it tends to preserve the integrity, stability, and beauty of the biotic community.
