Co-published by Greenpeace. Through stunning photographs, taken on a 16-month Defending Our Oceans expedition, Greenpeace reveals wonderful sights that few people have seen, and also some that certain people would like us not to see. Despite the vastness of the oceans we now know that they are in crisis, struggling to absorb the impact of our destructive ways. This is the story of our oceans - their extraordinary beauty and diversity of life - and the equally astounding ways in which they are exploited. Photographs by Daniel Beltra.
