"First published in Great Britain on 2009 by Mitchell Beazley"-- t.p. verso. Companion book to the television series. Includes bibliographical references (p. 315) and index.

In this companion book to the television series, six of the most spectacular natural phenomena on our planet are explored--the flooding of the Okavango Delta in Botswana; the melting of 10 million square kilometers of ice in the Arctic; the migration of the Serengeti; the great salmon run in British Columbia; the explosion of sea life in Alaska's coastal waters; and perhaps the greatest marine spectacle on the planet, the annual tide of sardines along South Africa's east coast.
