Human detritus: I just received Jim Schutze's article "Garbage to You" (January 13) in an e-mail from a friend in Manhattan. What a sad situation here, that we treat the poorest of us as detritus. This reminds me of the recent story of "Pale Male," the red-tailed hawk in New York whose nest was destroyed by Paula Zahn's husband simply because there were droppings on the Fifth Avenue sidewalk in front of their building. There, however, the nest was restored by public demand--and that for animals, not even humans. Thanks, Jim, for bringing this to our attention. My sympathy goes out to those affected.
