Ecological Economics represents the extension into economics of the thermodynamic revolution of the nineteenth and twentieth centuries. In physics, that revolution dethroned Newton and brought relativity. In biology, it was midwife to the birth of ecology, the study of ecosystems as wholes in which energy networks—food webs—are a defining structure. In chemistry the laws of thermodynamics brought clarity and rigor to a science that struggled to bring theoretical unity to diverse phenomena.
