“Human communities are ecosystems. Ecosystems are biological, chemical and physical systems. The physics, chemistry and biology of complex self-organizing systems can tell us much that is useful about human communities: about the conditions necessary for the existence of human communities, about the properties human communities 'inherit' because they are special cases of more general kinds of systems, particularly ecosystems.”
