Fish is often sold as the perfect climate-friendly dinner: highly nutritious and lower carbon than other forms of protein. But new research is increasingly bringing some of these eco marketing claims into question. In part, because industrial fishing – scientists and campaigners say – is weakening the ocean’s ability to act as a carbon sink. Over the last 60 years, the ocean, forests and other natural carbon sinks have absorbed over half of all man-made emissions, slowing down global warming. Yet, as temperatures rise, scientists warn such processes could be on the brink of collapse.
