Book excerpt: A very powerful chronicle of the St. Lawrence River Beluga whales which were hunted to near extinction until given legal protection in 1979, and are now quite literally dying from pollution. Beland (senior research scientist, St. Lawrence National institute of Ecotoxicology) describes the Beluga history, how they live now, the pollution threats to them, and ways in which this kind of tragedy can be prevented in the future, although it looks like it's too late for the Beluga; thus the volume also serves as their elegy. Includes color photographs. Annotation copyright by Book News, Inc., Portland, OR
