The poet Walt Whitman spoke of soil and earth as the great transformers, accepting “the leavings” of men and producing “such divine materials.” Whitman marveled at the ability of the earth to reabsorb the corrupt, the vile, the diseased, and produce new, pristine life. There is no reason to zap away your organic material with gas or flame when there is good to be done with “the leavings” of your mortal form.
