How to Think Like an Ecologist offers a witty and engaging guide to the science behind restoring the planet and, by association, ourselves. Aimed at non-science students, this book demystifies the basic science of environmental global changes, from climate change to biodiversity loss, while tackling the natural constraints that shape our future. The book dives into the unique power of science as a tool for uncovering truths about the natural world and equips readers with strategies to spot and counter scientific misinformation. Exploring how differing views of nature can spark conflict, it emphasises the importance of clarity and community in setting environmental priorities. To address environmental challenges requires a basic ecological literacy, so the science of ecology and evolution are examined. The text unpacks the interconnected crises we face, from plastic pollution, invasive species, ocean acidification, and more, arguing for holistic, systemic solutions. The final chapters inspire action, addressing what it takes to create a sustainable society and how to cultivate hope in these challenging times. Filled with innovative ideas and real-world examples, this alternative textbook is a must-read for students in introductory environmental courses and those in other disciplines seeking to grasp the fundamental science behind our rapidly changing global environment.
