Conservation is a state of harmony between men and land.
— Aldo Leopold
In essay "Conservation' (1953), Collected in Aldo Leopold and Luna B. Leopold, Round River (1972), 145.
Science quotes on:  |  Conservation (143)  |  Harmony (70)  |  Land (115)  |  State (136)

Conservation is getting nowhere because it is incompatible with our Abrahamic concept of land. We abuse land because we regard it as a commodity belonging to us. When we see land as a community to which we belong, we may begin to use it with love and respect. There is no other way for land to survive the impact of mechanized man, nor for us to reap from it the esthetic harvest it is capable, under science, of contributing to culture. 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. That land yields a cultural harvest is a fact long known, but latterly often forgotten.
— Aldo Leopold
A Sand County Almanac, and Sketches Here and There (1949), viii-ix.

Every farm woodland, in addition to yielding lumber, fuel, and posts, should provide its owner a liberal education. This crop of wisdom never fails, but it is not always harvested.
— Aldo Leopold
In A Sand County Almanac: and Sketches Here and There (1949, 1989), 73.

Having to squeeze the last drop of utility out of the land has the same desperate finality as having to chop up the furniture to keep warm.

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.
— Aldo Leopold
From 'Conservation' (c.1938), Round River: From the Journals of Aldo Leopold (1953), 141. Collected in The Essential Aldo Leopold: Quotations and Commentaries (1999), 142.

To save every cog and wheel is the first precaution of intelligent tinkering.
— Aldo Leopold

Twenty centuries of “progress” have brought the average citizen a vote, a national anthem, a Ford, a bank account, and a high opinion of himself, but not the capacity to live in high density without befouling and denuding his environment, nor a conviction that such capacity, rather than such density, is the true test of whether he is civilized.
— Aldo Leopold
In Game Management (1933), 423.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
