Interdependence is the mutual reliance between two or more groups. This concept differs from the reliance in a dependent relationship, where some members are dependent and some are not. There can be various degrees of interdependence. In an interdependent relationship, participants may be emotionally, economically, ecologically and/or morally reliant on and responsible to each other. An interdependent relationship can arise between two or more cooperative autonomous participants (e.g. a co-op). Some people advocate freedom or independence as the ultimate good; others do the same with devotion to one’s family, community, or society. Interdependence can be a common ground between these aspirations.
