Fishing trawls cause significant CO2 emissions as they stir up the carbon bound in the seabed and release it again. It is also clear that they drastically affect ecosystems in the ocean. A new study by the Helmholtz-Zentrum Hereon models the influence of bottom trawls on sedimentary carbon in the North Sea. It also shows that restrictions on fishing in certain areas would benefit life in the ocean and on land.
