Where did it originate?
The term Sustainable Development was first introduced to the world in the pages a 1987 report (Our Common Future) produced by the United Nations World Commission on Environmental and Development, authored by Gro Harlem Brundtland, VP of the World Socialist Party. The term was first offered as official UN policy in 1992, in a document called UN Sustainable Development Agenda 21, issued at the UNs Earth Summit, today referred to simply as Agenda 21.
Does anyone know which states have refused to submit to the Race To The Top (RTT) education portion of Agenda 21?
