Among the first people to live on the ocean were fishermen and sailors who spent months or years on ships, exploring or fighting in wars. Today, people live on the ocean for scientific study, work, or simply for fun. There are even entire villages that live by floating on the ocean. Through accessible text and vibrant photographs, young readers will understand how life on the water has changed over time and what the future holds. As land-based populations increase, resources dwindle and pollution levels rise. People are looking to the oceans as a more permanent solution, considering ideas like floating cities and undersea habitats. This book will intrigue young readers and help them to look at the oceans in a new, open-minded way.

The first edition of The Living Ocean, published in 1991 by Island Press in association with Friends of the Earth, was widely praised by scientists, policymakers, instructors, and general readers as a useful and accessible introduction to the science and policy of biological diversity in marine environments. Since that time, much new research has been conducted and numerous national and international policy initiatives have been undertaken.With 1998 designated by the United Nations as the International Year of the Ocean, this new, revised and expanded, edition is a welcome and much-needed addition to the literature.This edition brings the volume up-to-date, and re-establishes it as an essential primer for anyone wishing to gain an understanding of marine biodiversity and how it can be protected. It provides an overview of basic concepts and principles and a review of relevant policy issues and existing instruments. The author:defines biological diversity and discusses the importance of threats to marine biodiversity reviews the current status of scientific knowledge describes the major coastal and oceanic ecosystem types and addresses the major threats in each presents a general discussion of the ways in which government and the public can protect marine biological diversity provides specific examples of national and international policies, legal instruments, programs, and institutions addresses how social, economic, political, and ethical considerations affect decisions to conserve marine biological diversity considers the involvement of citizens in developing ocean policy The book also includes a useful glossary that provides information about basic biological concepts, and a comprehensive bibliography. Throughout, the author emphasizes the relationship of human societies and governments to the living ocean, and the need to implement programs that will protect ecosystems and species.

"Our Planet is surrounded by two great oceans," says Dr. Maury, the eminent American savant: "the one visible, the other invisible; one is under foot, the other over head. One entirely envelopes it, the other covers about two-thirds of its surface." It is proposed in "The Ocean World" to give a brief record of the Natural History of one of those great oceans and its living inhabitants, with as little of the nomenclature of Science, and as few of the repulsive details of Anatomy, as is consistent with clearness of expression; to describe the ocean in its majestic calm and angry agitation; to delineate its inhabitants in their many metamorphoses; the cunning with which they attack or evade their enemies; their instructive industry; their quarrels, their combats, and their loves. The learned Schleiden eloquently paints the living wonders of the deep: "If we dive into the liquid crystal of the Indian Ocean, the most wondrous enchantments are opened to us, reminding us of the fairy tales of childhood's dreams. The strangely-branching thickets bear living flowers. Dense masses of Meandrineas and Astreas contrast with the leafy, cup-shaped expansions of the Explanarias, and the variously-branching Madrepores, now spread out like fingers, now rising in trunk-like branches, and now displaying an elegant array of interlacing tracery. The colouring surpasses everything; vivid greens alternate with brown and yellow; rich tints, ranging from purple and deepest blue to a pale reddish-brown. Brilliant rose, yellow, or peach-coloured Nullipores overgrow the decaying masses: they themselves being interwoven with the pearl-coloured plates of the Retipores, rivalling the most delicate ivory carvings. Close by wave the yellow and lilac Sea-fans (Gorgonia), perforated like delicate trellis-work. The bright sand of the bottom is covered with a thousand strange forms of sea-urchins and star-fishes. The leaf-like Flustræ and Escharæ adhere like mosses and lichens to the branches of coral—the yellow, green, and purple-striped limpets clinging to their trunks. The sea-anemones expand their crowns of tentacula upon the rugged rocks or on flat sands, looking like beds of variegated ranunculuses, or sparkling like gigantic cactus blossoms, shining with brightest colours. "Around the branches of the coral shrubs play the humming-birds of the ocean: little fishes sparkling with red or blue metallic glitter, or gleaming in golden green or brightest silvery lustre; like spirits of the deep, the delicate milk-white jelly-fishes float softly through the charmed world. Here gleam the violet and gold-green Isabelle, and the flaming yellow, black, and vermilion-striped Coquette, as they chase their prey; there the band-fish shoots snake-like through the thicket, resembling a silvery ribbon glittering with rose and azure hue. Then come the fabulous cuttle-fishes, in all the diaphanous colours of the rainbow, but with no definite outline.

I have enjoyed writing this book. Some of my ideas are controversial. Some of them I know to be true though I have not sufficient evidence for a conviction. My intention is that you should realise that microbes will be as important in the future of the earth as they have been in the past. They have led to our existence, and may help to prevent our destruction; they may even save us from ourselves. i As a student, I was taught that a scientist must be objective, and that every statement or observation must be documented. Also, that a scien tist must seek the truth, and not be satisfied with less. It took me a long time to realize that no human being can be completely objective, and that the truth, even scientific truth, is a chimera. The most that we can get with our human minds and feeble experimentation is an approxima tion, and all we can hope to contribute is a better approximation than we have had to date. Newton's theories were regarded as absolute until Einstein came along; and now it seems that Einstein may be inadequate.
