Sustainable seafood is good both for the ocean environment and human health. In the first analysis of its kind, Leah Gerber (2011) and her colleagues brought together several types of sustainability rankings, along with species-specific health metrics, including omega-3 fatty acid and mercury content. The team hopes that the results will help inform consumers about the health risks and benefits of different seafood choices, while addressing the ecological impacts of fishing and fish farming. “We want to help people choose fish that are both eco-friendly and healthy,” Gerber says.
