This book examines the pressures now facing marine ecosystems, from plastic pollution and industrial fishing practices to rising sea temperatures and acidification. You will learn how these factors interact, why certain species and habitats are particularly vulnerable, and what scientists currently understand about the long-term consequences for biodiversity and coastal communities. The chapters draw on established research to outline the mechanisms behind ocean degradation and the efforts underway to address them. This book was written with the assistance of artificial intelligence and reviewed for accuracy and clarity. It offers a clear, factual introduction for readers who want to understand the state of the world's oceans and the challenges that lie ahead.The world's oceans cover more than seventy percent of the planet's surface and sustain life both in the water and on land.
