Replaceable natural resources such as soil fertility, grasses and trees can be restored and reproduced. Irreplaceable natural resources are exhausted by one use. In so far as they are concerned, that part of the earth's crust has been impoverished—made poorer.

Wasted through neglect and careless use, squandered in the senseless destruction of war, the earth is still a rich treasure house for its multitudinous forms of life. Its remaining treasures can be carefully conserved. Such replaceable resources as topsoil, vegetation and water can be husbanded. Oceans, mountains and, deserts can be dealt with as we proceed with our programs for the most economical use of the natural resources that remain to us.

Western man is presently emerging from a boisterous era of invention, discovery, of multiplying productivity and corresponding waste of irreplaceable natural resources-temporarily justified by "national security" and "war emergency." The temporary loss of replaceable reserves and the permanent loss of irreplaceable resources is none the less tragic, no matter how urgent the immediate cause for their consumption.

At this stage in the history of earth's conservation, when so much is waiting to be done, if each family, each village and town, each city state and nation will do its bit to conserve, plan, shape, utilize, beautify, improve what remains of the natural environment, the results will be impressive enough to justify the time and means devoted to the enterprise.

Wherever we go with our plea for the foresighted and economical use of the earth and its remaining resources, we are met with the question: "But what can I do?" The answer is simple. Find your place in the nearest team working to utilize, conserve, and, where possible, enlarge the natural wealth of the planet. If no such team exists, join with your neighbors in organizing one. Take seriously your assignment to use the part of the earth with which you are in contact intelligently, economically, wisely.

Whether you are a novice or a professional, a homesteader or a longtime resident, be sure that each contact you make with the earth enlarges its possibilities of utility, order, beauty.

This crusade to save and utilize the earth as the common mother of so many forms of life must be carefully planned and well organized through successive generations. Men have spent far too much time and energy in destroying. The time has come when they must conserve, plan, shape, utilize, beautify, improve.

If the energies now going into business, sport, social events, frivolities, make-believe and the deliberate destruction of waste and war could be directed to planning, utilizing, beautifying on the circumferences and at the centers of population concentrations, immense forward strides could be taken in a single generation.

The planet still has immense, unused or little used reserves of natural resources. The old order is slipping, floundering, wasting. Civilization has told the best of its story and is busy writing its epitaph. The revolution of 1750-1970 provides the opportunity for a new beginning. The place is here. The time is now. Let us conserve, beautify, share, utilize and, in so far as possible, improve our natural surroundings.
