The focus of the seventh edition of the World Ocean Review is on the impacts of climate change on the physics of the ocean and on its biotic communities; the consequences of fishing, shipping, resource extraction, energy generation and marine pollution; and the questions of how active substances from the ocean can be used and how the ocean can be managed in the future in such a way that both its protection and the participation of as many people as possible in its services and goods are guaranteed. The new WOR presents comprehensive solutions for sustainable use of the oceans in all thematic areas, describes best practice examples and refers to a large number of international marine protection agreements that are important instruments, but whose implementation has not been successful in many places to date.
