The word conservation has a thrifty
meaning. To conserve is to save and protect, to leave what we ourselves enjoy in
such good condition that others may also share the enjoyment. Our forefathers
had no idea that human population would increase faster than the supplies of raw
materials; most of them, even until very recently, had the foolish idea that the
treasures were "limitless" and "inexhaustible". Most of the citizens of earlier
generations knew little or nothing about the complicated and delicate system
that runs all through nature, and which means that, as in a living body, an
unhealthy condition of one part will sooner or later be harmful to all the
others. Fifty years ago nature study was not part of the school
work; scientific forestry was anew idea; timber was still cheap because it
could be brought in any quantity from distant woodlands; soil destruction and
river floods were not national problems; nobody had yet studied long-term
climatic cycles in relation to proper land use; even the word "conservation" had
nothing of the meaning that it has for us today. For the sake of
ourselves and those who will come after us, we must now set about repairing the
mistakes of our forefathers. Conservation should, therefore, be made a part of
everyone's daily life. To know about the water table in the ground is just as
important to us as a knowledge of the basic arithmetic formulas. We need to know
why all watersheds need the protection of plant life and why the running current
of streams and rivers must be made to yield their full benefit to the soil
before they finally escape to the sea. We need to be taught the duty of planting
trees as well as of cutting them. We need to know the importance of big, mature
trees, because living space for most of man's fellow creatures on this planet is
figured not only in square measure of surface but also in cubic volume above the
earth. In brief, it should be our goal to restore as much of the original beauty
of nature as we can.
