In today's Shared Planet we ask who is responsible for the life in the ocean? Featuring a field report from Scotland, Monty Don explores the problems faced by life trying to compete with us for resources in an area with little or no regulation. The Isle of May is home to a quarter of a million seabirds in the breeding season, yet come the winter months most disperse out to the open sea to spend weeks at the mercy of storms and cold weather. The birds need a rich food supply to survive, yet the fish stocks and all other life in the sea is at the mercy of humanity. Suffering from what is known as "The Tragedy of the Commons", no one owns the oceans and therefore no one has responsibility for them, they are open to exploitation from many nations.
