Activists on board the Rainbow Warrior hit the water today to demand immediate action to protect the endangered Mediterranean bluefin tuna from commercial extinction. They deployed buoys marked "Crime Scene" around cages holding bluefin tuna which are being fattened up for harvesting to then be sold for export -- mostly as luxury gourmet Sushi.

The action comes just days after the European Commission announced its support for a ban on trading North Atlantic and Mediterranean bluefin tuna, under rules governing the trade of endangered species. That's a great move, long overdue, but why, people, why do we continue to let the threat of extinction be the only really powerful regulator that the fishing industry has to face? What we really need, if we want fish for tomorrow, is Marine Reserves today.
