    While reading an article in the latest issue of Science, I could not help thinking of the lesson Tragedy in the Making, Fishing the Global Commons.  I really like this activity and the students love it.  However, I think you could add one more layer to the activity by supplementing the lesson with this article.  In the activity the students discuss the problems caused by overfishing for humans.  This article discusses the problems associated with overfishing for other organisms, in particular seabirds.  The lesson discusses types of fish and although it doesn't use the term forage fish it does discuss by-catch.  The article states that when the population of some species of forage fish drops below 2/3 of the maximum population, birds have fewer chicks.  I have included a link to the article below. 

    I really think that having the students look at this issue from a different point will place even a greater emphasis on the interconnectedness of life.
