Whether humans have duties directly to endangered species is a deeper question, part of the larger issue of biodiversity conservation. Many endangered species have no resource value, nor are they particularly important for the usual humanistic reasons: medical, industrial, agricultural resources, scientific study, recreation, ecosystem stability,. Many environmental ethicists believe that species are good in their own right, whether or not they are good for anything. The duties-to-persons-only line of argument leaves deeper reasons untouched. What may be required is not just prudence saving resources but principled responsibility to the Earth.born digitalchapters (layout features)eng©2010 Greenwood Press.Copyright and other restrictions may apply.
