"Damage to oceans is releasing vast amounts of CO2, despite efforts to market fish as a sustainable food."
"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.
A new study suggests that industrial fishing is also threatening the sea’s capacity to absorb carbon, by disrupting a process known as the ‘biological carbon pump’, which sees carbon sequestered as dead marine animals drop to the bottom of the ocean.
Estimates suggest humans catch between one and two trillion fish every year. This is adding stress to habitats already endangered by warming oceans, which are estimated to help feed over three billion people, and to be home to more than 700,000 different species."
