“The last word in ignorance is the man who says of an animal or plant, "What good is it?" If the land mechanism as a whole is good, then every part is good, whether we understand it or not. If the biota, in the course of aeons, has built something we like but do not understand, then who but a fool would discard seemingly useless parts? To keep every cog and wheel is the first precaution of intelligent tinkering.”
― Aldo Leopold, Round River: From the Journals of Aldo Leopold

“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.”
― Aldo Leopold

“There are two spiritual dangers in not owning a farm. One is the danger of supposing that breakfast comes from the grocery, and the other that heat comes from the furnace.”
― Aldo Leopold, A Sand County Almanac

“Examine each question in terms of what is ethically and aesthetically right, as well as what is economically expedient. A thing is right when it tends to perserve the integrity, stability, and beauty of the biotic community. It is wrong when it tends otherwise.”
― Aldo Leopold
