The Kingfisher Book of Oceans
The oceans and seas cover seven-tenths of our planet. The Pacific Ocean, the largest and deepest, could swallow up every continent, or all the water of the other three oceans combined. And yet even today Scientists know more about the surface of the Moon than they do about the oceans’ depths.
All plants and animals on Earth evolved from ancient seas, and the oceans continue to provide whole habitats and an abundance of life today. For centuries, however, people have viewed the oceans with awe, and often fear, and we are only just beginning to understand this watery world and its strange creatures.
The Kingfisher Young People’s Book of Oceans examines this vast subject from every angle, incuding the most up-to-date exploration of the seas by means of submersibles, underwater cameras, and oceanographic satellites. Sailors once measured depths by lowering cannonballs on piano wire. Today, cartographers can map underwater hills and valleys with the help of echo sounders and TV cameras. The book also stresses the mportance of protecting our oceans and the life in them from environmental damage caused by overfishing, oil spills, and other forms of pollution. The oceans hold the key to where we have come from and, in many ways, the key to our future.
