The general evolution of this soil is toward greater powers; and yet, so nicely balanced are these powers that within his lifetime a man may ruin any part of it that society allows him to hold; and in despair he abandons it and throws it back to nature to reinvigorate and to heal. We are accustomed to marvel at the power of man in gaining dominion over the forces of nature—he bends to his use the expansive powers of steam and the energy of the electric currents, and he ranges through space in the light that he concentrates in his telescope; but while he is doing all this he sets at naught the powers in the soil beneath his feet, wastes them, and deprives himself of vast sources of energy. Man will never gain dominion until he learns from nature how to maintain the augmenting powers of the disintegrating crust of the earth.
We can do little to control or modify the atmosphere or the sunlight; but the epidermis of the earth is ours to do with it much as we will. It is the one great earth resource over which we have dominion. The soil may be made better as well as worse, more as well as less; and to save the producing powers of it is far and away the most important consideration in the Conservation of natural resources.
No man has a right to plunder the soil
The man who owns and tills the soil owes an obligation to his fellowmen for the use that he makes of his land; and his fellowmen owe an equal obligation to him to see that his lot in society is such that he will not be obliged to rob the earth in order to maintain his life. The natural resources of the earth are the heritage and the property of every one and all of us. A man has no moral right to skin the earth, unless he is forced to do it in sheer self-defense and to enable him to live in some epoch of an unequally developed society; and if there are or have been such epochs, then is society itself directly responsible for the waste of the common heritage.
The man who plunders the soil is in very truth a robber, for he takes that which is not his own and he withholds food from the mouths of generations yet to be born. No man really owns his acres; society allows him the use of them for his life-time, but the fee comes back to society in the end. What, then, will society do with those persons who rob society? The pillaging or reckless land-worker must be brought to account and be controlled, even as we control other offenders.
(I know that the soil-depletion idea is now challenged; but I am sure that the Conservation ideal must be applied to soil maintenance even as it is applied to other maintenance. If it transpires that plants hold a different relation to the soil-content than we have supposed, we still know that poor farming makes the land unproductive and that the saving of wastes is a desirable human quality; and we shall probably need to change only our phraseology to make the old statement broadly correct.)
I have no socialistic program to propose. The man who is to till the land must be educated: there is more need, on the side of the public welfare, to educate this man than any other man whatsoever (applause). When he knows, and when his obligations to society are quickened, he will be ready to become a real conservator; and he will act energetically as soon as the economic pressure for land-supplies begins to be acute. When society has done all it can to make every farmer a voluntary conservator of the fatness of the earth, it will probably be obliged to resort to other means to control the wholly incompetent and the recalcitrant; at least, it will compel the soil-robber to remove to other occupation, if economic stress does not itself compel it. We shall reach the time when we shall not allow a man to till the earth unless he is able to leave it at least as fertile as he found it. (Applause)
It is a pernicious notion that a man may do what he will with his own. The whole tendency of social development is away from this idea. A person may not even have the full control of his own children: society compels him to place them in school, and it protects them from over-work and hardship. A man may not breed diseased cattle. No more should he be allowed wantonly to waste forests or to make lands impotent, even though he "owns" them. (Applause)
Ownership vs. Conservation
This discussion leads me to make an application to the Conservation movement in general. We are so accustomed to think of privileged interests and of corporation control of resources that we are likely to confuse Conservation with company ownership. The essence of Conservation is to utilize our resources with the least waste consistent with good progress, and with an honest care for the children of all generations.
