From human rights to land mines, sustainable development, and democratization, global problemsolving is increasingly being left to an agglomeration of unelected, often unaccountable transnational civil society actors.

The Union of International Associations lists over 15,000 internationally and regionally oriented nongovernmental organizations (Union of International Associations 1999).
