'Interdependence is not only a crucial skill for personal relationships; it is also an essential way of understanding and relating to both the social sphere and the ecosphere. The illusion of independence damages the the idividual and those who come into contact with him or her. It also damages society as a whole, and the whole planetary biosphere, when people believe that they can take without giving, and that taking does not make them dependent on the sources from which they take.'
Nick Totton in Guy Brandon, Just Sex, p.41.
