Is education possibly a process of trading awareness for things of lesser worth? The goose who trades his is soon a pile of feathers.
Aldo Leopold

What avail are forty freedoms without a blank spot on the map?
Aldo Leopold
Image
To build a road is so much simpler than to think of what the country really needs.
Aldo Leopold
Image
A peculiar virtue in wildlife ethics is that the hunter ordinarily has no gallery to applaud or disapprove of his conduct
Aldo Leopold
Image
Only economists mistake physical opulence for riches.
Aldo Leopold
Image
Civilization has so cluttered this elemental man-earth relationship with gadgets and middlemen that awareness of it is growing dim. We fancy that industry supports us, forgetting what supports industry.
Aldo Leopold
Image
The art of land doctoring is being practiced with vigor, but the science of land health is yet to be born.
Aldo Leopold
Image
One of the penalties of an ecological education is that one lives alone in a world of wounds.
Aldo Leopold
Image
There is, as yet, no sense of pride in the husbandry of wild plants and animals, no sense of shame in the proprietorship of a sick landscape. We tilt windmills in behalf of conservation in convention halls and editorial offices, but on the back forty we disclaim even owning a lance.

No one would rather hunt woodcock in October than I, but since learning of the sky dance I find myself calling one or two birds enough. I must be sure that, come April, there be no dearth of dancers in the sunset sky.

Conservation is a state of harmony between men and land.
Aldo Leopold
Image
Is it possible to preserve the element of Unknown Places in our national life? Is it practicable to do so, without undue loss in economic values? I say 'yes' to both questions. But we must act vigorously and quickly, before the remaining bits of wilderness have disappeared.
Aldo Leopold
Image
Individual thinkers since the days of Ezekiel and Isaiah have asserted that the despoliation of land is not only inexpedient but wrong. Society, however, has not yet affirmed their belief.
Aldo Leopold
Image
The last word in ignorance is the man who says of an animal or plant: 'What good is it?
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
This whole effort to rebuild and stabilize a countryside is not without its disappointments and mistakes... What matter though these temporary growing pains when one can cast his eye upon the hills and see hard-boiled farmers who have spent their lives destroying land now carrying water by hand to their new plantations
Aldo Leopold

Like all real treasures of the mind, perception can be split into infinitely small fractions without losing its quality. The weeds in a city lot convey the same lesson as the redwoods the farmer may see in his cow-pasture what may not be vouchsafed to the scientist adventuring in the South Seas.

Wilderness is the raw material out of which man has hammered the artifact called civilization. Wilderness was never a homogenous raw material. It was very diverse. The differences in the product are known as cultures. The rich diversity of the worlds cultures reflects a corresponding diversity. In the wilds that gave them birth.

No matter how intently one studies the hundred little dramas of the woods and meadows, one can never learn all the salient facts about any one of them.

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.
