"Hardly more than two generations ago Americans first woke up to the fact that their land was not inexhaustible. Every year since then more and more has been said, and at least a little more has been done about "conserving resources," about "rational use" and about such reconstruction as seemed possible. Scientists have studied the problem, public works have been undertaken, laws passed. Yet everybody knows that the using up still goes on, perhaps not so fast nor so recklessly as once it did, but unmistakably nevertheless. And there is nowhere that it goes on more nakedly, more persistently or with a fuller realization of what is happening than in the desert regions where the margin to be used up is narrower.
First, more and more cattle were set to grazing and overgrazing the land from which the scanty rainfall now ran off even more rapidly than before. More outrageously still, large areas of desert shrub were rooted up to make way for cotton and other crops watered by wells tapping underground pools of water which are demonstrably shrinking fast. These pools represent years of accumulation not now being replenished and are exhaustible exactly as an oil well is exhaustible. Everyone knows that
they will give out before long, very soon, in fact, if the number of wells continues to increase as it has been increasing. Soon dust bowls will be where was once a sparse but healthy desert, and man, having uprooted, slaughtered or driven away everything which lived healthily and normally there, will himself either abandon the country or die. There are places where the creosote bush is a more useful plant than cotton.
To the question why men will do or are permitted to do such things there are many answers. Some speak of population pressures, some more brutally of unconquerable human greed. Some despair; some hope that more education and more public works will, in the long run, prove effective. But is there, perhaps, something more, something different, which is indispensable? Is there some
missing link in the chain of education, law and public works? Is there not something lacking without which none of these is sufficient?
After a lifetime spent in forestry, wild-life management and conservation of one kind or another, after such a lifetime during which he nevertheless saw his country slip two steps backward for every one it took forward, the late Aldo Leopold pondered the question and came up with an unusual answer which many people would dismiss as "sentimental" and be surprised to hear from a "practical" scientific man. He published his article originally in the Journal of Forestry and it was reprinted in the posthumous volume, A Sand County Almanac, where it was given the seemingly neutral but actually very significant title "The Land Ethic."
This is a subtle and original essay full of ideas never so clearly expressed before and seminal in the sense that each might easily grow into a separate treatise. Yet the conclusion reached can be simply stated. Something is lacking and because of that lack education, law and public works fail to accomplish what they hope to accomplish. Without that something, the high-minded impulse to educate, to legislate and to manage become as sounding brass and tinkling cymbals. And the thing which is missing is love, some feeling for, as well as some understanding of, the inclusive community of rocks and soils, plants and animals, of which we are a part.
It is not, to put Mr. Leopold's thoughts in different words, enough to be enlightenedly selfish in our dealings with the land. That means, of course, that it is not enough for the farmer to want to get the most out of his farm and the lumberer to get the most out of his forest without considering agriculture and wood production as a whole both now and in the future. But it also means more than
that. In the first place enlightened selfishness cannot be enough because enlightened selfishness cannot possibly be extended to include remote posterity. It may include the children, perhaps, and grandchildren, possibly, but it cannot be extended much beyond that because the very idea of "self" cannot be stretched much further. Some purely ethical considerations must operate, if anything does. Yet even that is not all. The wisest, the most enlightened, the most remotely long-seeing exploitation of resources is not enough, for the simple reason that the whole concept of exploitation is so false and so limited that in the end it will defeat itself and the earth will have been plundered no matter how scientifically and farseeingly the plundering has been done.
To live healthily and successfully on the land we must also live with it. We must be part .not only of the human community, but of the whole community; we must acknowledge some sort of oneness not only with our neighbors, our countrymen and our civilization but also some respect for the natural as well as for the man-made community. Ours is not only "one world " in the sense usually implied by that term. It is also "one earth." Without some acknowledgment of that fact, men can no more live
successfully than they can if they refuse to admit the political and economic interdependency of the various sections of the civilized world. It is not a sentimental but a grimly literal fact that unless we share this terrestrial globe with creatures other than ourselves, we shall not be able to live on it for long.
You may, if you like, think of this as a moral law. But if you are skeptical about moral laws, you cannot escape the fact that it has its factual, scientific aspect. Every day the science of ecology is making clearer the factual aspect as it demonstrates those more and more remote interdependencies which, no matter how remote they are, are crucial even for us."
