About this Issue:
It seems there are stories on cloning everywhere (including here!). The ethical questions that cloning raises certainly warrant the amount of attention they are receiving. The purpose of this issue was not only to inform (and add to the many cloning stories out there) but provide a forum for our readers to discuss these important issues and to make their opinions known. We look forward to reading your contributions to this discussion.
