Published in 2018 by the University System of Georgia, Introduction to Environmental Science is now in its second edition and remains a great tool for educators teaching environmental science or studies and related courses. The textbook encompases biology, earth sciences, environmental policies, and resource management practices, and helps readers prepare for the "unprecedented environmental challenges," facing the planet. Topics are divided between eight chapters, beginning with an introductory chapter and then diving into topics such as energy resources, climate science, and water cycles. Each chapter begins with a list of learning outcomes, which help orient students towards concepts they should focus on. In addition to being completely open access, with options to view online (via the "Link to Full Text" button) and downloaded in its entirety or as individual chapters, the textbook also has accessible formats. Readers can download these versions in both PDF and Word formats, with optical character recognition (OCR) and auto-tagging. The textbook is authored by Caralyn Zehnder, Kalina Manoylov, Samuel Mutiti, Christine Mutiti, Allison VandeVoort, and Donna Bennett, with support from a Round Two ALG Textbook Transformation Grant.
