A VERY special and important book for young readers written by a highly respected and often referenced scientist, Dr. Rachel Carson, author of "Silent Spring". Appropriate for age group pre-teen through high school years. Very nice pictorial cover of a rocky coast and the sea. This is not a simplistic picture book, but is actually a well-written and comprehensive scientific text. A must for every young person interested in environmental sciences. "The fascinating story of the oceans of the earth and the life they support, especially adapted for young readers from the original text of Rachel Carson's magnificent best-seller. With more than 150 marine photographs, maps and drawings in color and black-and-white."
