 Social ecologists assert that the present ecological crisis has its roots in human social problems and that the domination of human-over-nature stems from the domination of human-over-human.Bookchin later developed a political philosophy to complement social ecology which he called Communalism (spelled with a capital "C" to differentiate it from other forms of communalism).While originally conceived as a form of social anarchism, he later developed Communalism into a separate ideology which incorporates what he saw as the most beneficial elements of anarchism, Marxism, syndicalism and radical ecology.
