No man may rightly fail to take a great pride in what has been accomplished by means of the destruction of our natural resources so far as it has gone. It is a paradoxical statement, perhaps, but nevertheless true, because out of this attack on what nature has given we have won a kind of prosperity and a kind of civilization and a kind of man that are new in the world. For example, nothing like the rapidity of the destruction of American forests has ever been known in forest history, and nothing like the efficiency and vigor and inventiveness of the American lumberman has ever been developed by any attack on any forests elsewhere. Probably the most effective tool that the human mind and hand have ever made is the American axe. So the American business man has grasped his opportunities and used them and developed them and invented about them, thought them into lines of success, and thus has developed into a new business man, with a vigor and effectiveness and a cutting-edge that has never been equalled anywhere else. We have gained out of the vast destruction of our natural resources a degree of vigor and power and efficiency of which every man of us ought to be proud. Now that is done. We have accomplished these big things. What is the next step? Shall we go on in the same lines to the certain destruction of the prosperity which we have created, or shall we take the obvious lesson of all human history, turn our backs on the uncivilized point of view, and adopt toward our natural resources the average prudence and average foresight and average care that we long ago adopted as a rule of our daily life? The conservation movement is calling the attention of the American people to the fact that they are trustees. The fact seems to me so plain as to require only a statement of it, to carry conviction. Can we reasonably fail to recognize the obligation which rests upon us in this matter? And, if we do fail to recognize it, can we reasonably expect even a fairly good reputation at the hands of our descendants? Business prudence and business common-sense indicate as strongly as anything can the absolute necessity of a change in point of view on the part of the people of the United States regarding their natural resources. The way we have been handling them is not good business. Purely on the side of dollars and cents, it is not good business to kill the goose that lays the golden egg, to burn up half our forests, to waste our coal, and to remove from under the feet of those who are coming after us the opportunity for equal happiness with ourselves. The thing we ought to leave to them is not merely an opportunity for equal happiness and equal prosperity, but for a vastly increased fund of both.
