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 after the BP oil spill, 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.
