The seas and oceans cover more than two-thirds of the surface of our planet. They provide us with food and energy, help regulate the daily weather and are a vital habitat for millions of plants and animals. Without them, life on Earth would not exist. Seas and Oceans takes an innovative and informative look at this important environment, explaining how oceans form, the cause of waves, tides and currents, how the sea shapes the land and how we make use of the oceans, often with alarming consequences. It also looks at methods of protecting the oceans and their inhabitants, as well as describing recent exciting discoveries and developments in underwater exploration.
