November 3, 2023 — Over 90 percent of global blue food production faces substantial risks from environmental changes, with leading seafood-producing countries – including China, Norway, and the U.S. – running the highest risks, according to a new study.
Published in the scientific journal Nature Sustainability, the study, “Vulnerability of blue foods to human-induced environmental change,” included a global analysis assessing the vulnerability of countries’ fisheries and aquaculture production in the face of anthropogenic impacts, or environmental changes directly caused by human activities. Specifically, anthropogenic threats can reduce the amount of high-quality blue food countries can produce by altering water quality and habitats, causing shifts or declines in stocks, and compromising food safety by contaminating fish with pathogens or pollutants that are toxic for human consumption.
