According to ecological economists, conventional economics does not reflect adequately the value of essential factors like clean air and water, species diversity and social and generational equity. This introductory-level textbook is designed specifically to address this significant flaw in economic thought. The second edition of Ecological Economics provides a clear, readable and easy-to-understand overview of a field of study that continues to grow in importance. It remains the only stand-alone textbook that offers a complete explanation of theory and practice in the discipline.
