Aldo Leopold (1887-1948)
• Professor• Sand County Almanac (1949)• Land Ethics, Environmental Ethics,
Nature and Wildlife Preservation
All ethics so far evolved rest upon a single premise: that the individual is a member of a community of interdependent parts.
That land is a community is the basic concept of ecology, but that land is to be loved and respected is an extension of ethics.
The land ethic changes the role of Homo Sapiens from conqueror of the land-community to plain member and citizen of it.
We abuse land because we regard it as a commodity belonging to us. When we see land as a commodity to which we belong, we may begin to use it with love and respect.
Anything is right when it tends to preserve the integrity, stability, and beauty of the biotic community.
It is wrong when it tends otherwise.
