““People in every generation...have found their joys and happiness [in nature]. Those in middle latitudes have thanked God for the green Earth, the lilies of the field and the golden corn, those in other latitudes for the beauty of the polar and mountain snows, the shelter of the northern forests, the great arch of the desert sky, or the big trees and flowers of the equatorial forest. How many of our present problems arise from not understanding our environment and making unrealistic demands on it?””
