This concise volume presents an excellent synopsis of many of the key articles describing the Earth's condition. In convenient form, this book presents the selections in such a way that they can easily be used for undergraduate courses. Any active ecologist or student of biology would have need to refer to many of these. By exposing undergraduate students to these articles, careers in biology will be stimulated and enhanced. Outstandingly useful!
