The Natural World Museum (NWM) was a mobile institution based in San Francisco, California that presented art as a catalyst to inspire and engage people in environmental awareness and action.
NWM designed curatorial programs that offered new and creative perspectives on specific environmental themes such as green cities, desertification, and global climate change.
For the 2007 World Environment Day exhibit, Envisioning Change: Melting Ice / A Hot Topic, NWM commissioned Alfio Bonnano to create a site-specific outdoor nature installation entitled "Ark", depicting a boat balanced in the treetops.
In 2007, NWM published a book entitled Art in Action: Nature, Creativity, and Our Collective Future, with a foreword by Achim Steiner, Executive Director of the United Nations Environment Programme, and containing artworks by Christo and Jeanne-Claude, Joseph Beuys, Ed Burtynsky, Ken Rinaldo, and Cai Guo-Qiang, among others.
NWM also held an ongoing lecture series and annual international symposium that bridged the worlds of art, science, and the environment, featuring guest speakers such as Al Gore, Ernest Callenbach, Hunter Lovins, Joanna Macy, Daryl Hannah, and Wangari Maathai, Nobel Laureate 2004.
