N2  - Oceans cover over 70% of the Earth's surface and the marine environment supports a vast variety of life, from bacteria and plankton to the blue whale. In this Very Short Introduction, Philip V. Mladenov describes the various marine ecosystems from shorelines and coral reefs to the depths of the ocean, and their diversity of organisms. He explains the crucial role of marine life in the cycling of nutrients; the threats from overfishing, pollution, and climate change; and approaches to effective management and conservation of one of our planet's most precious resources
