Marine reserve status for whole Arctic region is best way to protect it

The question that the scientists at the Institute of Marine Research in Norway have to answer is why it would not be in the best interests of the whole area to have marine reserve status as its default position (Targeted marine protection provides best hope for the Arctic, Letters, theguardian.com, 11 March)?

This would mean that no fishing could take place (be licensed) unless that proposal to fish could prove that it was not injurious. This is exactly what all other human marine activities have to do, so why should fishing be exempt?
