By creating new alliances between the humanities and the environmental sciences, the Environmental Arts and Humanities Initiative offers educational, research, and outreach programs that will help humankind make the difficult turn toward a more sustainable life on Earth. Our times present challenges that are unprecedented in their complexity, danger, and scale. At the same time, they present correspondingly important opportunities. Meeting these challenges and opportunities will require new ideas and new forms of intellectual and cultural leadership based on a scientific understanding of Earth’s environmental and ecological systems, and grounded in a deep understanding of the sources of human wisdom and values. Neither the sciences nor the humanities can meet the challenges alone. Together, we have a chance.
