This series investigates the world above and below the surface of the seas and oceans. The books describe in detail the wildlife of the sea, how the seas were formed and why they are constantly changing, the latest developments in sea exploration and recent discoveries on the ocean floor. They also look at the sea as a source of food and minerals, examining the worldwide effects of over-fishing and pollution, and suggesting the measures that need to be taken in order to save the sea and its wildlife for future generations. The world's oceans and seas are extremely valuable as an important food source for humans. This book explains the various methods, both traditional and modern, employed to harvest this food source - which includes fish, crustaceans and seaweeds. The author discusses: the fine balance between financially economical fishing and the serious problems of over-fishing; the dangers to other sea creatures, such as dolphins and seals, which are often killed by long lines and drift nets; and the need to stop polluting the oceans and seas which give us such an important resource.
