The part of the talk that interested me most was that about climate feedback. We talked today in class about how the inertia of the CO2 emissions means that ppm in atmosphere will continue to grow even if we stop emitting altogether. In other words, rising CO2 emissions lead to climate change which leads to even more CO2 emissions. These self-reinforcing effects - in conjunction with the sun, other greenhouse gases, ect - are driving climate change. I just found this aspect of her talk especially interesting since it relates so well to what we were talking about in class today.

Being from the gulf coast area, I would like to spend tomorrow's class examining the breadth of the economic impact caused by the BP oil spill. I know it devastated the gulf coast region's aquatic life which had a trickle down effect, affecting the restaurant business and others. Is there a total economic value that can be placed on that? What effect is the spill still affecting the gulf coast today?

This paper explores the very interesting trade-off between short term financial benefits and a variety of long term benefits (that don't exactly fit into that category of "financial"). This issue, as the paper indicates, is primarily a problem in small fishing based communities whose citizens have few options other than fishing and agricultural work. The paper uses a model to determine the effectiveness of different types of policies enacted to ensure a MPA. They basically fall under two different categories: 'stick' and 'carrot' incentives. The 'stick' incentives (i.e. enforcement by fine) was shown to have the greatest impact on the reduction of fishing; however, it also lowered the overall wellbeing of the community. Perhaps this short term dip in livelihood is compensated for in the future when the fish stocks are repleted, but I must ask, is it worth it? If a long time fisherman is now forced to earn his keep in the field, are the short term economic burdens that he endures truly compensated for in the future? In a MPB-MPC sense, I would argue that no, he is not compensated. The social benefit of enacting and enforcing an MPA may far outweigh the social cost, but I believe that it comes at the expense of the small fisherman, who cannot afford to change his line of work.

I find it interesting the way the author(s) discuss the monetary value of certain benefits of coral reefs and their inhabitants. For example, as diving instructors indicate, sea turtles are valuable because people love to encounter them on scuba trips. Their benefits extend beyond just their aesthetic value, however, they also help prevent disease and mediate sponge-coral interactions, which can be harmful to coral reefs. How does one place a value on that? More importantly, if policy makers choose to enact a policy of sea turtle conservation (in areas where harvesting turtle is still legal) what are the economic ramifications? Perhaps even more importantly, how do the policy makers justify these seemingly immeasurable, long term benefits against these very quantifiable short term losses? These are some of the questions that the authors raise and that I find very interesting.
