This book documents the intersection of architecture and design with ecology, environmental history, policy, governance and law from the 19th century to today. It will present conflicting definitions and concepts of architects and designers and the parallel histories of their intellectual positions toward environmental thoughtout time. Arguably, ecological design starts with the reconceptualization of the world as a complex system of flows rather than a discrete compilation of objects, which visual artist and theorist György Kepes has described as one of the fundamental reorientations of the 20th century.
