This book examines sustainability as both a system‑wide challenge and a lived human experience, drawing on a wide range of credible, publicly available sources, including peer‑reviewed research, international reports, government and biodiversity data, technical studies, and investigative journalism. Emphasizing recent and well‑documented material, it situates sustainability debates within current environmental, social, and economic realities.
The analysis takes an interdisciplinary and life‑cycle approach, integrating environmental science, social equity, and development studies to explore how technologies, materials, and policies shape outcomes from resource extraction to end of life. Through real‑world examples-from energy systems and waste to digital infrastructure and displacement-the book highlights recurring patterns rather than isolated cases, asking who benefits, who bears the costs, and how impacts accumulate over time. Quantitative evidence is paired with human narratives to ensure clarity without abstraction, and uncertainty is treated transparently where data is incomplete. The result is a thoughtful, rigorous guide that equips readers to evaluate sustainability claims critically and understand their real‑world consequences with depth and care.
