It is imperative to maintain portions of the wilderness untouched so that
a tree will rot where it falls, a waterfall will pour its curve without generating
electricity, a trumpeter swan may float on uncontaminated water and moderns
may at least see what their ancestors knew in their nerves and blood.
Bernard De Voto
Animals are, like all living things, self-building, self-maintaining, and self-protecting
embodiments of their genetic designs, and they are therefore in human eyes objects
of their own operations.
A. VAN GINKEL, General Principles of Human Power
