ZERO: A Landscape of Conversation and Action

Last year artist Catherine Leberg created a sculpture consisting of over 1000 cups which represent the amount of water an average American uses in a day. Through this project Leberg, anthropologist Adrian Cerezo, and photographer Carly Ann Hilo, are revitalizing the sculpture and using it as a foundation for dialogue and action on comprehensive sustainability.

From July 30 to August 3, the cups will be installed at the Pulitzer and locations around the city, creating landscapes which invite the community to contribute their own thoughts, meditations, and ideas. Operating on the belief that sustainability must integrate both dialogue and action simultaneously, the trio will encourage visitors to leave these thoughts and ideas in exchange for a cup to take home. Cards designed with photographs of the cups and a rotation of the 15 themes of the UN Sustainability Agenda Post 2015, social media, and blank notebooks will be provided.

As cups are taken, and stories left in their place, the landscape of the sculpture will change and begin to describe a regional dialogue that will in turn provide a ripe scene to photograph and assess the current state of awareness, knowledge, skills and values regarding sustainable development in Saint Louis.

What would all of this be without an eventual gathering, however? The project will end with a potluck at the Pulitzer with a free and open invitation. Here people can write more ideas, share stories, and view the end of the Dialogues together.

Following this weekend, Dr. Cerezo will use the project to expand upon and develop concrete programs and activities that illustrate each human being’s inherent involvement in sustainability, and leverage this awareness into diverse and deliberate positive actions.


Catherine Leberg is a recent graduate of the Washington University Sculpture program. Her work concerns environmental issues, with a particular focus on empowering people to create environmental change in their communities through dialog and action.

Carly Ann Hilo is a photographer who specializes in documentation, fine art, and portraits. She currently is co manager of Enamel, an experiential art space. Beginning her photography career 5 years ago in New Mexico, she has since worked with arts organizations such as 516ARTS in Albuquerque, NM, Pulitzer Arts Foundation, and the Saint Louis Art Museum. Incorporating her desire to teach and share, she uses her photography to observe and bring awareness to surroundings and the spaces that people inhabit.

Dr. Adrian Cerezo holds a PhD in Environmental Studies with a concentration in Social Ecology from Yale University. For twenty years he has explored environmental education and conservation from multiple perspectives: as student, researcher, teacher, trainer, evaluator of programs, designer of curricula, developer of education materials, writer of children’s books, participant in international forums, developer and designer of out-of-school programs, consultant for museum designs, and manager of education programs. Adrián is currently the Associate Director for Conservation Education Research at the St Louis Zoo, policy consultant for UNICEF, fellow at Yale University’s Zigler Center, and Adjunct Professor of International Environmental Policy at the University of Missouri, Saint Louis.
