8．The word"conservation"has a thrifty （节俭）meaning．To conserve is to save and protect，to leave what we ourse1ves 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 this foo1ish idea that the treasures were"1imitless"and"inexbaustible"．Most of the citizens or earlier generations knew little or nothing about the complicated and delicate system that runs all through nature，and which means that，as in a 1iving body，an unhealthy condition of one part will sooner or 1ater be harmful to a11the others．
??Fifty years ago nature study was not part of the schoo1work； scientific forestry was a new idea：timber was still cheap because it could be brought in any quantity from distant woodlands； soil destruction and river f1oods were not national problems； nobody had yet studied long-term climatic cycles in relation to proper 1and 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（地下水位） 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 river 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．
