(Colorado State University. Libraries, 1988) Rolston, Holmes, 1932-, speaker; Bend, Ron, speaker and filmmaker
Rolston walking in the aspen in Colorado mountains notices the great detail there, such as the mosses, the lichens, the insects, biological diversity and wealth. These may be important in ecosystems, but the rare ones often are not, still they contribute to the richness of life on Earth. We ought to care for, to celebrate their conservation.
