IS HUMANITY SUICIDAL?
Edward O. Wilson argues that we must save other species, not for their own sake, but so "they can be understood and employed in the fullest sense for human benefit" ("Is Humanity Suicidal?" May 30). What is needed, instead, is to see human beings merely as one part of the whole earth system and probably as that part whose job is to bring about healing, where previously we have caused destruction and degradation.
