Clear As Crystal, Red As Flame: Later Chinese Glass

Addresses the problem that human activities are threatening more species than can be preserved by existing or foreseeable financial and organizational resources. Biologists, economists, and resource managers discuss criteria for choosing which ones to save, and review preservation techniques. The six essays, with commentaries and summaries of the discussions, are from a June 1985 conference near Seattle. Annotation copyright Book News, Inc. Portland, Or.
