Strengthening the role the United Nations can play...will require serious examination of the need to extend into the international arena the rule of law and the principle of taxation to finance agreed actions which provide the basis for governance at the national level.

A shift is necessary toward lifestyles less geared to environmental damaging consumption patterns.

Occupy World Street is a masterpiece which deserves to get wide circulation and commitment by world leaders.
