The oceans of the world rank foremost among humankind's last great frontiers, and their climatological and ecological workings remain mysterious to all but specialists. In this lively, well-written survey, marine scientist Carl Safina encourages readers to take a wider interest in the oceans, especially because so much of that great blue expanse is now threatened by human progress. Safina notes, for example, that the North Atlantic's tuna population has fallen by more than 90 percent in just the last few decades. It has gone the way of cod and herring and pilot whales thanks to a combination of changing global temperatures, overfishing, pollution, inland watershed and delta destruction, and other causes--many of them attributable to human activities. Even now, he notes, many Pacific fishing fleets use cyanide to catch fish, a process that destroys sensitive marine ecosystems. Safina's tour of the world's waters may inspire readers to press for changes in the way that fish is brought to their tables, and to take a more careful look at the natural processes that govern this watery planet.

Other than fishers and oceanographers, few people have taken note of the worldwide decline of fish populations. Sounding an alarm, Safina argues that we must extend a sense of biological community to ocean animals.
