Greenpeace activists from the MY Rainbow Warrior form a symbolic 'tuna graveyard' with mock crosses and display a banner saying "SOS Mediterranean" inside a tuna ranch in Cartagena, Southeast Spain. They call for the immediate closure of the Mediterranean bluefin tuna fishery until it can be properly managed and the adoption of urgent measures, including the establishment of a network of marine reserves to protect 40% of the Mediterranean Sea and regenerate its fish stocks.
