Classical economics is a mythology. Predatory capitalism is a fundamentalist religion based on this mythology. Environmental destruction and income inequality are results of the practice of this mythical religion. But is the present economic and environmental situation a conscious conspiracy or an unintended consequence of simplistic beliefs supported by basic human greed?This book provides the basics of classical economic theory and the description of the intended or unintended consequences of predatory capitalism based on this theory. It contrasts these to sustainability principles underpinning modern environmental economic theory and the various movement towards corporate responsibility.This book is not meant to be an academic or scientific exercise for economists or policy makers. The concepts discussed are easily accessible to thoughtful readers. My objective was to explain to myself the structure of influence that is at the heart of environmental degradation (including the welfare of individual human beings). Understanding is the foundation of action.
