"Great Pacific Garbage Patch" by Nsikan Akpan

Question

What weighs more than 43,000 cars and is twice the size of Texas? The Great Pacific Garbage Patch. A new analysis, published Thursday in Scientific Reports, reveals the makeup of this massive collection of floating trash in the North Pacific in a way that’s never been done before. The patch weighs 87,000 tons — 16 times more than previous estimates — and contains more than 1.8 trillion pieces of plastic, the study shows. But its findings on the individual pieces of plastic inside the patch might hold the key to cleaning up this human-made mess.What the scientists did: Plastics tend to break down, due to heat and sunlight exposure, into small particles known as microplastics. In the past, scientists estimated the size of the Great Pacific Garbage Patch by hopping on a boat and trawling the trash with fine nets — nets originally designed for catching plankton. Running these nets through the patch, which extends from California to Hawaii, was not only laborious, it failed to catch big things like bottles and buoys. Scientists tried counting these larger items by eye, but they could only do so for small sections of the patch. By extrapolating, they could develop a sense of the Great Pacific Garbage Patch size, but their final estimates — especially for large pieces of trash — varied dramatically. Three year ago, The Ocean Cleanup foundation opted for a more direct approach. The Netherlands-based organization hired 18 ships to trawl at different spots across the whole patch. But they used 652 nets capable of catching microplastics or larger trash. The international team took the extra step of conducting aircraft surveys — covering 120 square miles and snapping 7,300 photographs — so they could better calculate the amount of large pieces of plastic. Then, like prior studies, the team used math models and ocean current projections to estimate the scale of the Great Pacific Garbage Patch.What they found: The Great Pacific Garbage Patch stretches across 617,000 square miles of the northern Pacific Ocean, based on their survey, and plastics make up 99.9 percent of the trash in the patch. And while 1.8 trillion pieces of plastic might seem extraordinary, oceanographer Laurent Lebreton of The Ocean Cleanup foundation said the composition of the Great Pacific Garbage Patch is the noteworthy takeaway. While microplastics made up 94 percent of the total number of pieces of plastic in the patch, they only accounted for 8 percent of the mass. That means the overwhelming bulk of the Great Pacific Garbage Patch is large pieces of trash. Most are hard plastics — think plastic food containers, bottles, lids, buckets, ropes and lots of fishing nets. Fishing nets made up nearly half the plastic discovered. The large and medium-sized plastics bigger than 2 inches, known as megaplastics and macroplastics, comprised more than 75 percent of the total mass of the Great Pacific Garbage Patch.Based on inscriptions, most of the plastic collected in the study originated in Asia — namely China and Japan — but that makes sense given the North Pacific Current runs west to east. The oldest piece of plastic they found dated to 1977. Why it matters: “We provide a better understanding on the distribution of plastics — on what they are, what size and how often we can find them,” Lebreton said. “That can help engineers to design solutions to collect the plastic.” Not only can conservationists use this data to design the right nets for cleaning the patch, but these numbers create a baseline for tracking the progress of the cleanup. For instance, by comparing their data to prior studies, they learned the concentration of microplastics has rapidly grown — tripling in the Great Pacific Garbage Patch since the 1970s. This summer, The Ocean Cleanup foundation will lead an expedition to remove this plastic from the sea. They hope to clean up 50 percent of the patch within the next five years. The project will cost about $370 million, which they plan to finance by selling corporate sponsorships for the cleanup vessels.But even if they wipe out the Great Pacific Garbage Patch, more trash will await. Four additional giant garbage patches exist in the ocean’s gyres, in the south Pacific, the north and south Atlantic and the Indian Oceans. Lebreton said those other patches may not contain as much trash as the Great Pacific Garbage Patch, but they cover areas of similar size.

Book Review: "Great Pacific Garbage Patch" by Nsikan Akpan

Nsikan Akpan's compelling exploration of the Great Pacific Garbage Patch offers a detailed insight into one of the most pressing environmental crises facing our planet today. Akpan presents a thorough analysis of the patch, describing not only its sheer scale but also the alarming composition of plastic waste that constitutes this floating landfill. With its staggering weight of 87,000 tons and an estimated 1.8 trillion pieces of plastic, the Great Pacific Garbage Patch serves as a sobering reminder of humanity's impact on the oceans.

Content Evaluation

The book dives deep into the methodology employed by scientists to analyze the patch, highlighting both traditional and innovative approaches to oceanic research. Previously, estimations of the patch's size relied heavily on manual trawling, which was both labor-intensive and imprecise. Recent advancements, as described through the efforts of The Ocean Cleanup foundation, showcase a modern approach that combines extensive ship surveys and aerial photography to provide more accurate data. This meticulous attention to methodology not only enhances the credibility of the findings but also underscores the importance of adapting scientific practices to meet the needs of complex environmental issues.

One fascinating aspect of Akpan's narrative is the revelation about the distribution of plastic within the patch. While microplastics account for an overwhelming majority of the pieces, they represent only a small fraction of the total mass, indicating that large plastic debris like fishing nets and containers contribute significantly to the pollution. This finding serves as critical information for engineers and conservationists working on cleanup solutions.

The author also contextualizes the issue by noting the geographic origins of the plastic waste, most notably from Asia, which resonates with the reader's understanding of ocean currents and global waste management practices. Furthermore, the historical perspective provided by the age of the oldest piece found adds a poignant touch to the narrative, reminding us of the long-term consequences of our consumption habits.

Presentation Evaluation

Akpan's writing style is engaging and informative, making complex scientific concepts accessible to a broader audience. The use of vivid imagery and relatable comparisons—such as describing the patch as "twice the size of Texas"—helps to illustrate the enormity of the issue. The structure of the book flows logically, with each section building upon the last, culminating in a call to action for collective responsibility towards ocean conservation.

Illustrations and data visualizations could enhance the presentation further by providing a visual representation of the statistics discussed. However, the textual descriptions alone effectively convey the urgency of the issue and the necessity for immediate intervention.

Conclusion

In conclusion, Akpan's examination of the Great Pacific Garbage Patch serves as a crucial resource for understanding the scale and implications of plastic pollution in our oceans. It not only informs readers about the specifics of the patch but also emphasizes the need for innovative cleanup solutions and greater awareness of our environmental footprint. As the world grapples with the aftermath of plastic waste, Akpan's work is timely and essential, prompting readers to reflect on their choices and encouraging a collective effort towards mitigating this critical challenge.
