The first observation that must be apparent to all men is that our dominion has been mostly destructive. We have been greatly engaged in digging up the stored resources, and in destroying vast products of the earth for some small kernel that we can apply to our necessities or add to our enjoyments. We excavate the best of the coal and cast away the remainder; blast the minerals and metals from underneath the crust, and leave the earth raw and sore; we box the pines for turpentine and abandon the growths of limitless years to fire and devastation; sweep the forests with the besom of destruction; pull the fish from the rivers and ponds without making any adequate provision for renewal; exterminate whole races of animals; choke the streams with refuse and dross; rob the land of its available stores, denuding the surface, exposing great areas to erosion. Nor do we exercise the care and thrift of good housekeepers. We do not clean up our work or leave the earth in order. The remnants and accumulation of mining-camps are left to ruin and decay; the deserted phosphate excavations are ragged, barren, and unfilled; vast areas of forested lands are left in brush and waste, unthoughtful of the future, unmindful of the years that must be consumed to reduce the refuse to mould and to cover the surface respectably, uncharitable to those who must clear away the wastes and put the place in order; and so thoughtless are we with these natural resources that even the establishments that manufacture them--the mills, the factories of many kinds--are likely to be offensive objects in the landscape, unclean, unkempt, displaying the unconcern of the owners to the obligation that the use of the materials imposes and to the sensibilities of the community for the way in which they handle them. The burden of proof seems always to have been rested on those who partake little in the benefits, although we know that these non-partakers have been real owners of the resources; and yet so undeveloped has been the public conscience in these matters that the blame--if blame there be--cannot be laid on one group more than on the other. Strange it is, however, that we should not have insisted at least that those who appropriate the accumulations of the earth should complete their work, cleaning up the remainders, leaving the areas wholesome, inoffensive, and safe. How many and many are the years required to grow a forest and to fill the pockets of the rocks, and how satisfying are the landscapes, and yet how desperately soon may men reduce it all to ruin and to emptiness, and how slatternly may they violate the scenery! All this habit of destructiveness is uneconomic in the best sense, unsocial, unmoral. Society now begins to demand a constructive process. With care and with regard for other men, we must produce the food and the other supplies in regularity and sufficiency; and we must clean up after our work, that the earth may not be depleted, scarred, or repulsive.
