GlobalNet21 started as 21st Century Network in April 2007 to discuss some of the great issues of the 21st century and then follow this up with further debate and action. It is about enlarging the Public Square where debate takes place using social networks to bring new audiences of people into that debate.
GlobalNet21 believes that the coming century will be one of the most critical facing the human race and that if we do not tackle the great inequalities within societies and between them then the future will be one of conflict and turmoil. GlobalNet21 embraces the humanistic values of global compassion, personal self-discovery, shared development, planetary concern and a love of community; and it is committed to a more equal society where all are valued.
