Agricultural science is largely a race between the emergence of new pests and the emergence of new techniques for their control.

More quotes by Aldo Leopold

Image
Sometimes in June, when I see unearned dividends of dew hung on every lupine, I have doubts about the real poverty of the sands. On solvent farmlands lupines do not even grow, much less collect a daily rainbow of jewels.
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

That the situation appears hopeless should not prevent us from doing our best.
Aldo Leopold
Image
Our children are our signature to the roster of history our land is merely the place our money was made. There is as yet no social stigma in the possession of a gullied farm, a wrecked forest, or a polluted stream, provided the dividends suffice to send the youngsters to college. Whatever ails the land, the government will fix it.

Patriotism requires less and less of making the eagle scream, but more and more of making him think.
Aldo Leopold
Image
The whole conflict thus boils down to a question of degree. We of the minority see a law of diminishing returns in progress our opponents do not.

We Americans, in most states at least, have not yet experienced a bear-less, eagle-less, cat- less, wolf-less woods. Germany strove for maximum yields of both timber and game and got neither.
Aldo Leopold
Image
Ideas, like men, can become dictators. We Americans have so far escaped regimentation by our rulers, but have we escaped regimentation by our own ideas? I doubt if there exists today a more complete regimentation of the human mind than that accomplished by our self-imposed doctrine of ruthless utilitarianism.

A peculiar virtue in wildlife ethics is that the hunter ordinarily has no gallery to applaud or disapprove of his conduct
Aldo Leopold
Image
Two things hold promise of improving those lights. One is to apply science to land-use. The other is to cultivate a love of country a little less spangled with stars, and a little more imbued with that respect for mother-earth - the lack of which is, to me, the outstanding attribute of the machine-age.

Wildlife administration, in this respect, is not yet a profession.
Aldo Leopold
Image
Wilderness is a continuous stretch of country preserved in its natural state, open to lawful hunting and fishing, big enough to absorb a two weeks' pack trip, and kept devoid of roads, artificial trails, cottages, or other works of man.
Aldo Leopold
Image
Thus far we have considered the problem of conservation of land purely as an economic issue. A false front of exclusively economic determinism is so habitual to Americans in discussing public questions that one must speak in the language of compound interest to get a hearing.
Aldo Leopold
Image
Our remnants of wilderness will yield bigger values to the nation's character and health than they will to its pocketbook, and to destroy them will be to admit that the latter are the only values that interest us.

I love all trees, but I am in love with pines.

A profession is a body of men who voluntarily measure their work by a higher standard than their clients demand. To be professionally acceptable, a policy must be sound as well as salable. Wildlife administration, in this respect, is not yet a profession.
Aldo Leopold
Image
Mechanized recreation already has seized nine-tenths of the woods and mountains a decent respect for minorities should dedicate the other tenth to wilderness.

Our ability to perceive quality in nature begins, as in art, with the pretty.

Image
One of the penalties of an ecological education is that one lives alone in a world of wounds.
Aldo Leopold

Conservation is a positive exercise of skill and insight, not merely a negative exercise of abstinence and caution.
