This is another book from the Greenpeace stable with an emphasis on conservation - and quite right too! Anything and everything to do with the North Sea is included here. Shipbuilding, seaweed harvesting, day-trips to the beach, the oil industry, fishing and, of course pollution. Expertly laid out so that the reader is able to build on the knowledge gained from what has been read so far, we commence with the sea's hidden wealth and the human tide of invasion. The author then compares the present with the past before detailing the huge varieties of marine life to be found.
