A Crowded Ark

This is a good book. It lays out the groundwork for the survival of several species in a way that might not immediately have occurred to you. It explains in plain and readable English what zoological breeding programs are like, how they are administered and coordinated and how they really are the only hope of preserving some animals now tentatively upon this earth. The title comes because not all threatened species can be saved. This book may change the way you look at zoos and breeding programs.
