The report gives a broad analysis of the issue of marine plastic ingestion, from albatrosses to zooplankton (literally A-Z!!!) The first part summarizes the cause for and effects of ingested marine debris on a variety of marine species: The causes widely depend on where the species looks for food, the type of food each species ingests, and distinct physical qualities that could endanger them. The effects are based off of what type of marine plastic was ingested and how long it was in the system, and can be separated into two categories: physical and physiological. The size and shape of objects can do a lot of damage to the digestive tracts of many species, while the toxins inside the plastics can also have adverse effects on them just as well. The second part of the report denotes what is still missing from research and the problems they pose, such as our underestimate of marine debris due to the possibility of deeper accumulations of marine plastics we have yet to find. Also, there is a lot to further examine in area of toxicology the interaction of predator and prey in this circumstance.
Group #4 is exploring the how plastics affect all sorts of marine species. What drew us to this report was its promise to “summarize the “state of the science” regarding the effects of ingested marine debris and highlight areas where knowledge is currently lacking“. The organized and understandable collection of information combined with a critical lens for the missing pieces in the research made it an easy read and a very telling one that is serving as a springboard to our project. I think everyone can gain from reading this report, as it states what we do know and what we don’t in a way that leaves the door open to further effective investigation of this meaningful topic.
Great desciption of the resource Elisabeth. Both you and Chris (in the post before this one) talk about how more people should care or would care if they understood the scope of the issue or its impacts on them. On the other hand, our attention span or attention capacity has got to have a limit. There are so many things to worry and care about. It can seem overwhelming, and then we shut down. This is a known phenomenon that I should probably look up and share with next year’s MCHC 2001 class.
