All our seas feed into one true ocean, interconnected and interdependent. Producing over half of the world's oxygen, our planet's ocean is a natural and vital wonder. As well as supporting a vast array of life, it plays a crucial role in regulating our weather and climate and it supplies us with food, medicine, recreation and a means of transport. Now it is under threat from many sides, such as overfishing, climate change and pollution to name a few. From the still waters of the Caribbean coastlines to the choppy North Sea, the Polar regions to the coral reefs, this book celebrates the essential ecosystems of our ocean around the world, providing a pictorial record of this wondrous world that needs our protection.
