Quote by Aldo Leopold
"An ethical obligation on the land is something so new in human history that our speculative philosophers have not yet devised a name for it."
More from Aldo Leopold
"In every walk with nature, one receives far more than he seeks."
"The land ethic simply enlarges the boundaries of the community to include soils, waters, plants, and animals, or collectively: the land."
"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."
"Conservation is a state of harmony between men and land."
