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.
Discusses conditions affecting populations of various species, causes and effects of animal explosions and invasions, man's influence on animal populations, and the problems of expanding human population.
