Wilderness is a resource which can shrink but not grow.
Aldo Leopold
Image
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.
Aldo Leopold
Image
One of the penalties of an ecological education is that one lives alone in a world of wounds.
Aldo Leopold
Image
Time was when education moved toward soil, not away from it.
Aldo Leopold
Image
All history consists of successive excursions from a single starting-point, to which man returns again and again to organize yet another search for a durable scale of values.
Aldo Leopold

No important change in ethics was ever accomplished without an internal chage in our intellectual emphasis, loyalties, affections, and convictions.
Aldo Leopold
Image
Harmony with land is like harmony with a friend you cannot cherish his right hand and chop off his left.
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.
Aldo Leopold
Image
Bread and beauty grow best together. Their harmonious integration can make farming not only a business but an art the land not only a food-factory but an instrument for self-expression, on which each can play music to his own choosing.

In that year [1865] John Muir offered to buy from his brother ... a sanctuary for the wildflowers that had gladdened his youth. His brother declined to part with the land, but he could not suppress the idea: 1865 still stands in Wisconsin history as the birth-year of mercy for things natural, wild, and free.

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.

Land health is the capacity for self-renewal in the soils, waters, plants, and animals that collectively comprise the land.
Aldo Leopold
Image
There is time not only to see who has done what, but to speculate why.

A peculiar virtue in wildlife ethics is that the hunter ordinarily has no gallery to applaud or disapprove of his conduct
Aldo Leopold

There are idle spots on every farm, and every highway is bordered by an idle strip as long as it is keep cow, plow, and mower out of these idle spots, and the full native flora, plus dozens of interesting stowaways from foreign parts, could be part of the normal environment of every citizen.

Wilderness is the raw material out of which man has hammered the artifact called civilization.

On motionless wing they emerge from the lifting mists, sweep a final arc of sky, and settle in clangorous descending spirals to their feeding grounds. A new day has begun on the crane marsh.

The problem, then, is how to bring about a striving for harmony with land among a people many of whom have forgotten there is any such thing as land, among whom education and culture have become almost synonymous with landlessness. This is the problem of conservation education.

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.

There can be no doubt that a society rooted in the soil is more stable than one rooted in pavements.
