More quotes by Aldo Leopold

Image
In farm country, the plover has only two real enemies: the gully and the drainage ditch. Perhaps we shall one day find that these are our enemies, too.
Aldo Leopold
Image
Examine each question in terms of what is ethically and aesthetically right, as well as what is economically expedient.
Aldo Leopold
Image
If we lose our wilderness, we have nothing left, in my opinion, worth fighting for or to be more exact, a completely industrialized United States is of no consequence to me.
Aldo Leopold
Image
That the situation appears hopeless should not prevent us from doing our best.
Aldo Leopold
Image
All ethics so far evolved rest upon a single premise: that the individual is a member of a community of interdependent parts. . . The land ethic simply enlarges the boundaries of the community to include soils, waters, plants, and animals, or collectively: the land.
Aldo Leopold
Image
Education, I fear, is learning to see one thing by going blind to another.
Aldo Leopold
Image
I do not imply that this philosophy of land was always clear to me. It is rather the end result of a life journey.
Aldo Leopold
Image
To those who know the speech of hills and rivers straightening a stream is like shipping vagrants—a very successful method of passing trouble from one place to the next. It solves nothing in any collective sense.
Aldo Leopold
Image
The oldest task in human history: to live on a piece of land without spoiling it.
Aldo Leopold
Image
The land-relation is still strictly economic, entailing privileges but not obligations
Aldo Leopold
Image
What conservation education must build is an ethical underpinning for land economics and a universal curiosity to understand the land mechanism. Conservation may then follow.
Aldo Leopold
Image
The outstanding scientific discovery of the twentieth century is not television, or radio, but rather the complexity of the land organism.
Aldo Leopold
Image
When some remote ancestor of ours invented the shovel, he became a giver: He could plant a tree. And when the axe was invented, he became a taker: He could chop it down. Whoever owns land has thus assumed, whether he knows it or not, the divine functions of creating and destroying plants.
Aldo Leopold
Image
Our ability to perceive quality in nature begins, as in art, with the pretty.
Aldo Leopold
Image
No important change in ethics was ever accomplished without an internal chage in our intellectual emphasis, loyalties, affections, and convictions.
Aldo Leopold
Image
To keep every cog and wheel is the first precaution of intelligent tinkering.
Aldo Leopold
Image
Never did we plan the morrow, for we had learned that in the wilderness some new and irresistible distraction is sure to turn up each day before breakfast. Like the river, we were free to wander.
Aldo Leopold
Image
It is, by common consent, a good thing for people to get back to nature.
Aldo Leopold
Image
What avail are forty freedoms without a blank spot on the map?
Aldo Leopold
Image
Prudence never kindled a fire in the human mind I have no hope for conservation born of fear.
Aldo Leopold
