What Is Ecological Economics?

What is ecological economics, and how does it differ from mainstream (or neoclassical) economics? Ecological economics began in part as an attempt to bring together ecology and economics - to bridge the gap between a natural and social science. Today it a transdisciplinary field that covers topics from degrowth to the Doughnut of social and planetary boundaries. In this short lecture, I discuss the history, fundamental vision, and modern focus of ecological economics.
