    The sea contains millions of species of animals and plants, but we have identified only a few thousand of them. The sea controls our planet's climate, but we do not really understand how. The sea is still the frontier, and yet it seems so familiar that we sometimes forget how little we know about it. Just as we are poised on the verge of exploiting the sea on an unprecedented scale—mining it, fertilizing it, fishing it out—this book reminds us of how much we have yet to learn. More than that, it chronicles the knowledge explosion that has transformed our view of the sea in just the past few decades, and made it a far more interesting and accessible place. From the Big Bang to that far-off future time, two billion years from now, when our planet will be a waterless rock; from the lush crowds of life at seafloor hot springs to the invisible, jewel-like plants that float at the sea surface; from the restless shifting of the tectonic plates to the majestic sweep of the ocean currents, Kunzig's clear and lyrical prose transports us to the ends of the Earth.Originally published in hardcover as The Restless Sea.

       Striking paintings, from an adorable wolf pup to a wide range of modern-day dog breeds, illustrate this insightful story of teamwork and friendship. Through the eyes of a prehistoric boy and a lone wolf pup, we see how the bond between our ancestors and these wild animals may have developed. Starting as enemies competing for food, the wolf and the boy realize that they’ll eat better and be safer if they team up. Over time, others catch on, and as many of the wolves become more domesticated, the humans breed them for skills like hunting, herding, pulling, and rescuing. And today, there are more breeds of dog than of any other animal, all thanks to this relationship that started so long ago.
