In the movie clip, Rediagnosing Oceans (http://www. shiftingbaselines. org/videos/video18.htm), The narrator suggests that we have done a poor job of evaluating what the cause of certain problems has been in the oceans. He cites three examples as evidence (sea lions, kelp beds and sea turtles). By reviewing the history of these organisms, it was concluded that the scientists got it wrong and upon looking at the history of these organisms, they came up with a new diagnosis. In your opinion, what was the ultimate cause of all of the problems for all of the organisms? How do you think can fix that?
