Abstract

Urban greening offers an opportunity to reinforce food security and safety. Seagrass ecosystems can reduce human bacterial pathogens from coastal sources, but it remains unknown whether this service is conferred to associated food fish. We find a 65% reduction in human bacterial pathogens from marine bivalves experimentally deployed across coastal urban locations with seagrass present compared with locations with seagrass absent. Our model estimates that 1.1 billion people reside in urban areas within 50 km of a seagrass ecosystem. These results highlight the global opportunity to support human health and biodiversity sustainability targets.
