Aesthetic value and ingestion by marine organisms, for example, is the first topics related to plastic debris covered in this paper, and coincidentally are also two of the major components used in raising awareness of the public to marine pollution issues. Additional topics, which are less frequently known to the public, in this paper include smothering, unnatural and increased growth of flotsam, and the migration of invasive species.
The preventative measures offered in this paper are scant, despite there being an evident critique of beach clean-up procedures. Gregory seems to offer that other methods must be created or refined in order to better combat the threat of plastic debris. While beach clean-ups, international conferences, and an increasing amount of research has certainly provided an introduction into solving this issue, the sources of marine plastic debris must be handled more effectively. Most importantly, according to Gregory, is the “further development of biodegradable plastics with significantly reduced and tightly managed disintegration times.” This is not fully discussed however, and so, further research would need to be examined to better grasp how this technological development can occur. Data not disclosed in this paper, such as the density and specific disintegration times of different plastics, would help in this assessment.
This review paper solidifies the notion there need to be more attention devoted toward understanding the different impacts of plastic debris and preventative solutions, as opposed to a narrower view on their affects and a focus on post-contamination solutions.
Thoughtful post Cale and I like the critique that you brought into it. We ended up discussing the value of beach clean ups in class, and how there’s conflicting views on this. These sort of civic engagement projects can be important for raising awareness of issues and therefore have an indirect impact on the problem. But cleaning up beaches is clearly not a long term viable solution to the plastics issue.
