"The ocean is largely unexplored." So states the seventh and final Ocean Literacy principle, a series of fundamental concepts to help us better understand the ocean's influence on us and our influence on the ocean. World Ocean Radio's Ocean Literacy series continues this week with a discussion about how little we know about the ocean, and the need to designate vast marine protected areas around the world in order to protect the planet's natural biodiversity (known and unknown) from further destruction. This episode is part eight of a nine-part series on Ocean Literacy, an anthology of reflections, examples and illustrations that represent responses to the ocean and the environmental challenges we face.
