Can you imagine a world without fish? It’s a frightening, cataclysmic premise, and worst of all, it’s happening right now. A Sea Change follows the journey of retired history teacher Sven Huseby on his quest to discover what is happening to the world’s oceans. After reading Elizabeth Kolbert’s “The Darkening Sea,” Sven becomes obsessed with the rising acidity of the oceans and what this “sea change” bodes for mankind. His quest takes him to Alaska, California, Australia, and Norway as he uncovers a worldwide crisis that most people are unaware of. Speaking with oceanographers, marine biologists, climatologists, and artists, Sven eventually discovers that global warming is only half the story of the environmental catastrophe that awaits us. A Sea Change is also a touching portrait of Sven’s relationship with his grandchild Elias. As Sven keeps a correspondence with the little boy, he mulls over the world that he is leaving for future generations. A disturbing and essential companion piece to An Inconvenient Truth, A Sea Change brings home the indisputable fact that our lifestyle is changing the earth, despite our rhetoric or wishful thinking.
