See the grading rubric [12] for specifics on how this assignment will be graded.
Visit WPSU's Marine Fisheries & Aquaculture Series [9] and read about the problems with overfishing. This PBS documentary is a must see. You may be able to get it from your local library. If not you could buy it (it's a great thing to show to your classes). I've also collected a few youtube links with interesting shorts on related topics.
