A new report reveals that Norwegian fish farms release nitrogen, phosphorus, and organic carbon at levels comparable to the raw sewage of millions of people. This nutrient runoff leads to algal blooms and oxygen depletion in fjords, threatening marine ecosystems. While the industry argues that current production remains within nature's carrying capacity, environmental data shows a steady increase in feed consumption and waste. The pollution is particularly damaging in semi-enclosed fjords where oxygen levels are already dropping due to rising ocean temperatures.
