Why do species become endangered? How are scientists learning about endangered wildlife? What are people doing to conserve species and how can young people help? This book is richly illustrated with unique photos that Isabelle has taken over many years of observing endangered species in the field alongside the people who work to conserve them. Throughout, the author shares enchanting encounters and personal field stories: watching narwhals socialize in the Canadian Arctic, getting close to a Laysan albatross raising chicks on a remote Hawaiian island, spotting a rhinoceros on safari and even swimming with sea lions in the Galápagos Islands. Gone is Gone will inform, intrigue and inspire readers to take small steps toward big changes for endangered species around the world. The epub edition of this title is fully accessible.
