Witness To A Changing Earth

Book excerpt: This book is of interest to all of you willing to gain perspective both in time and in depth about the global environmental crises we are facing in the Anthropocene as well as pondering potential solutions. Humans are dominating the Earth’s environment and causing global changes in the most recent geologic time called the Anthropocene. Global changes are caused by both natural events like earthquakes and volcanic eruptions, or caused by humans like global warming and pollution of air, water, and soil. The author documents all types of global changes, beyond climate change, pointing out the risks for humanity when all these changes combine in time. Hans Nelson describes global changes while traveling through an earth scientist’s 60-year global journey. Throughout his memoirs, the author provides many humorous examples of adventures taking place during the scientific studies on land and at sea. He makes suggestions for a sustainable planet and shows that humans worldwide in the past, and can in the future, work together on solutions for global change problems. Students can use this book to learn about the many aspects of global change and methods that marine geologists use to obtain data on geologic hazards, resources, and environmental changes.
