Life on Earth is shaped by water, and only survives here because of it, but our ocean ecosystems are at the epicentre of global warming.

This enormous blue wilderness contains somewhere between half and three quarters of all life on Earth, including the biggest and most numerous creatures to ever live. But more than 90 per cent of Earth's warming since 1950 occurred in oceans, despite their vast capacity to absorb heat and CO2.

Framed by the need to protect our fragile oceans, Water World is natural-history illustrator Ben Rothery's rich exploration of the creatures from the coastal and offshore waters of the world - from penguins, seagulls, polar bears and seahorses, to plankton, sharks and deep-sea beings. Discover the longest migration and the loudest animal on Earth, and learn how our own actions affect the ocean, its inhabitants and our whole planet.

You’ll spend your WHOLE LIFE in your body. So it’s only fair you know how it works, right? This book will teach you EVERYTHING you need to know about the machine that is YOU. From your astonishing brain to your hard-working heart. Get ready for the BIG questions, like: How many muscles do you move playing Fortnight? (A twitch of a thumb on the controller uses TEN muscles) Are chillis actually HOT? (Short answer: no. We’ve been fooled by a plant.) How far can we sneeze? (Your sneeze droplets can reach up to eight meters – which means you could sneeze over an entire class.) You’ll also meet people like Chevalier Jackson, who collected things that people had swallowed by accident (for science, of course). And learn about why we poo (and why it smells). Packed with facts, history and humour, this beautifully illustrated book, from global bestselling science and history author Bill Bryson (ask your mum, he’s the one with the beard), will help you understand the secrets to our bodies and brains.
