This volume is a co-operative venture of the Global Ecological Integrity Project and the Earth Charter Initiative. In June 2000, the Integrity Project convened an international conference on Connecting Environmental Ethics, Ecological Integrity, and Health in the Millennium in San Jose, Costa Rica. Many chapters originate from this event, but the authors have also encouraged modifications and received new contributions to address their theme: Just Ecological Integrity: The Ethics of Maintaining Planetary Life .
