Editor’s note: In 2012, the US state of California formally adopted a statewide network of 124 marine protected areas (MPAs), covering over 16% of state waters. A new book Beyond Polarization: Public Process and the Unlikely Story of California's Marine Protected Areas analyzes what allowed the California Marine Life Protection Act (MLPA) Initiative to succeed in a time of political polarization and fiscal constraint. We interviewed book author Steven Yaffee and process participant Kaitilin Gaffney to get their perspectives about the MLPA Initiative and how conservation action can be achieved at times of political polarization. Yaffee is a professor of natural resources and environmental policy at the University of Michigan, and Gaffney is director of the Ocean, Coast, and Fisheries Program at the Resources Legacy Fund, which oversaw the MLPA Initiative, a public-private partnership between the state of California and philanthropic donors. She participated in the MLPA Initiative as director of the Pacific Program of Ocean Conservancy.
