Sala et al.1 present a framework for designing and assessing the benefits of a global network of marine protected areas (MPAs) for biodiversity, carbon sequestration, and food security. However, the model used to project these benefits makes a series of insufficiently tested or justified assumptions. We show that a more defensible model greatly alters the map of priority MPA areas and reduces food benefits by 62%.
