"The land ethic simply enlarges the boundaries of the community to include soils, waters, plants, and animals, or collectively: the land . . . a land ethic changes the role of Homo sapiens from conqueror of the land- community to plain member and citizen of it."

Aldo Leopold, The Land Ethic (1949)

"It is inconceivable to me that an ethical relation to land can exist without love, respect, and admiration for land, and a high regard for its value. By value, I of course mean something far broader than mere economic value; I mean value in the philosophical sense"

Aldo Leopold, The Land Ethic (1949)

"A thing is right when it tends to preserve the integrity, stability, and beauty of the biotic community. It is wrong when it tends otherwise"

Aldo Leopold, The Land Ethic (1949)
