The world's oceans make up 99 per cent of the living space on our planet and are home to more than half of all the earth's creatures. They are our life support, regulating the global climate and when this delicate ecosystem is threatened, so is our survival. The first book to look at the planetary environmental crisis through the lens of the global ocean, Seasick dives down on a journey through the planet's hidden realms. Each chapter features a different group of researchers who explore the importance of ocean currents, the effects of acidification or the extinction of marine species. With award-winning journalist Alanna Mitchell at the helm, readers submerge 3000 feet to gather sea sponges that may help to cure cancer, see first-hand the lava lamp-like 'dead zone' covering 17,000 square kilometres in the Gulf of Mexico, and witness the simultaneous spawning of corals under a full moon in Panama. Seasick will give you a new reverence for the source of all life on earth.
