A fascinating look at the future of our oceans—and how human actions may change them. The Earth—our home—is covered mostly with water: the wide, deep, salty, and very blue ocean. It regulates our climate in a way that makes life as we know it possible. This huge ocean is full of an amazing amount of life, most of which is too small to see. But life in the ocean is in trouble. The ocean is becoming hotter, more polluted, and, in places, empty of life. The right amount of warming is good for us, but too much warming is causing shifts that are not good for life in the ocean. Global warming, pollution, and overfishing are creating a New Ocean, in which life is changing drastically. This book tells the stories of the probable fates of six sea dwellers: jellyfish, orcas, sea turtles, tuna, corals, and blue-green algae. What becomes of them may help you understand what becomes of us. Praise for Bryn Barnard’s Outbreak! and Dangerous Planet: "An absorbing narrative that includes touches of humor. . . . Teachers will find many uses for this, but the book is so engaging it will also attract browsers—and hold them.” —Booklist, Starred “An engrossing introduction for young adult readers to the chillingly topical subject of man vs. microbe.” —The Wall Street Journal
