Why do we try to preserve wild animals? Why do we set aside delightful scenes of nature? Why do we establish open spaces and national parks? Would it not be better to accept here and now that man in his dominion over all the lesser creatures has every right to divest the land of animals, trees, or anything else which may stand in his way, or hinder him in exploiting the earth for the alleged well-being of mankind? Vast sums are spent in the larger continents to control domestic animal diseases; greater sums are spent in denuding the face of the earth of its natural cover, so that there can be more room for cattle, crops, factories and cities, in an attempt to meet the insatiable clamour of millions of human beings. Should we not pause to assess what irreplaceable assets are being endangered by this scramble and to what extent those assets contribute to men's peace of mind?
