Chapter 2 of <a href=\"https:\/\/islandpress.org\/books\/poison-no-other#desc\">A Poison Like No Other<\/a>, by Matt Simon, published by Island Press, and posted here with permission.<\/em><\/p><p>Every day, ocean life embarks on a mass migration that puts a bird flock or reindeer herd to shame. When the sun\u2019s up, animals large and small hang out in the relative safety of deeper, darker waters, where their predators can\u2019t see them. But at night, they move en masse to surface waters, where there\u2019s more sustenance\u2014and more microplastics they mistake for sustenance. The extreme diversity of microplastics, all shapes and sizes and colors, provides a diversity of different-looking \u201cfood\u201d for different foragers with different diets.<sup>46<\/sup>&nbsp;Indeed, a 2009 expedition in the Pacific Ocean collected fishes and found microplastic in the stomachs (they didn\u2019t look in the rest of the digestive system) of 4.8 percent of species that don\u2019t do this kind of vertical migration, as it\u2019s known, while 11.6 percent of migrating species tested positive for plastic.<sup>47<\/sup>&nbsp;This suggests that the migrants are picking up more particles closer to the surface when they feed, whereas the non-migrating fishes feed exclusively in depths, where there may be fewer microplastics. All told, these researchers calculated that in the gyre that forms the Great Pacific Garbage Patch, fishes consume up to 53 million pounds of plastic debris each year just in the mesopelagic zone, between 650 and 3,300 feet deep. Migratory species are therefore acting as vehicles to disperse microplastics farther down the water column: when they return to the darkness of the depths and poop, out come the particles. The fecal matter and microplastics join all the other organic debris from giant larvacean houses and decaying organisms to make marine snow, which falls to the seafloor and accumulates as sediment.<\/p><p>So even in the deepest depths, ocean life is feeding on microplastics. Between 2008 and 2017, oceanographers visited nine sites, ranging from 23,000 feet to 36,000 feet at the Challenger Deep in the Mariana Trench (the deepest point in the ocean), and collected amphipods, crustaceans that look like shrimp.<sup>48<\/sup>&nbsp;At every site, at least half of the animals had microplastic in their guts. The Mariana Trench\u2019s amphipods had <em>all <\/em>ingested microplastic, and they tallied the highest average particle count per individual among the nine sites. The vast majority of these particles were fibers. A separate expedition found up to 2,200 microplastics per liter of sediment from the Mariana Trench, so it\u2019s no wonder the animals down there are so contaminated.<sup>49<\/sup><\/p><p>In another survey in the middle of the Atlantic, three-quarters of captured deep-sea fishes had microplastics in their bellies.<sup>50<\/sup>&nbsp;One specimen of a common fangtooth had two prey in its stomach, a cock-eyed squid and a bearded sea devil, which themselves had microplastics in their guts. (As a general but informal rule, scientists tend to give deep-sea animals names that are at once fantastical and perfectly descriptive. The fangtooth has a mouth full of giant teeth, one of the cock-eyed squid\u2019s peepers is enlarged to collect faint light from above, and the bearded sea devil grows frilly bioluminescent structures on its chin.) This reveals a dynamic called trophic transfer: a small species eats microplastic, then a predator eats that small species, and a still larger predator eats that predator<sup>51<\/sup>\u2014a perpetual biological cycling of microplastics. If you were to somehow instantly remove all the particles from ocean waters and sediments, they\u2019d live on by transferring from gut to gut. Everything eats, everything gets eaten, and microplastics go along for the ride.<\/p><p>Microplastics aren\u2019t just in the food chain\u2014they\u2019ve penetrated the very <em>base <\/em>of the food chain. Surface waters teem with little organisms collectively known as plankton, which are divided into two groups. We\u2019ve got bacteria and algae known as phytoplankton, which harvest their energy from the sun. Though individual phytoplankton are microscopic, great blooms of them create green clouds that drift along the surface of the world\u2019s oceans. Like plants do on land, these photosynthetic organisms take in the carbon dioxide dissolved in seawater and spit out oxygen, and a whole lot of it: they\u2019re responsible for two-thirds of the atmosphere\u2019s oxygen content.<sup>52<\/sup>&nbsp;The carbon the organisms absorb goes the other way, sinking to the seafloor when the phytoplankton die. These life forms, then, are critical actors in the carbon cycle, sequestering CO<sub>2<\/sub> and locking it in the ocean depths.<\/p><p>They\u2019re also a critical source of food for the other group of plankton: zooplankton. These include tiny species of animals like crustaceans and jellyfish and marine worms. To reproduce in the open ocean, a female fish releases masses of eggs and a male releases sperm, which all drift around in planktonic clouds. When those eggs hatch into larval fish, they become more active participants in the community, eating phytoplankton and each other. They are, in turn, eaten by bigger fish and seabirds.<\/p><p>Now you can add microplastic as a third player to the vast planktonic universe sparkling across Earth\u2019s oceans. Scientists have analyzed a trove of stashed-away plankton samples, collected off the coast of Scotland since the 1960s, and found a significant rise in microfiber contamination over the decades\u2014a sad echo of Jennifer Brandon\u2019s sediment samples.<sup>53<\/sup>&nbsp;Others have taken water samples off Antarctica and found zooplankton tangled up in microfibers.<sup>54<\/sup>&nbsp;Biologists not only find petroplankton and biological plankton mingling together in water samples taken from different depths but also find the particles mingling in the stomachs of captured zooplankton: baby salmon that (eventually) feed bears and humans, the crustaceans that feed fish and birds, the krill that feed whales.<sup>55<\/sup>&nbsp;A survey in the South China Sea tested fish larvae, jellyfish, shrimp, and predatory worms and found microplastics in them all.<sup>56<\/sup>&nbsp;Adult fish that feed on zooplankton, or on smaller fish that feed on zooplankton, then assume the particles: a sampling in the remote South Pacific turned up microplastics in 97 percent of fish species, including mahi-mahi, red snapper, and barracuda<sup>57<\/sup>\u2014one foot-long Pacific chub was burdened with 104 pieces of plastic in its gut. It\u2019s worth noting that the most contaminated fish were in the most remote waters, around Easter Island, where the South Pacific Gyre\u2014the counterpart of the North Pacific Gyre, which creates the Great Pacific Garbage Patch\u2014accumulates plastic.<\/p><div class=\"gb-container gb-container-3cd5d471\">\n<div class=\"gb-grid-wrapper gb-grid-wrapper-06dd3dcf\">\n<div class=\"gb-grid-column gb-grid-column-db5cb743\"><div class=\"gb-container gb-container-db5cb743\">\n<h3 class=\"gb-headline gb-headline-feb2560d gb-headline-text\"><a href=\"https:\/\/www.resilience.org\/stories\/2025-05-08\/live-event-troubled-waters-how-microplastics-are-impacting-our-oceans-and-our-health\/\">Troubled Waters: How Microplastics Are Impacting Our Oceans and Our Health<\/a><\/h3>\n\n<div class=\"gb-headline gb-headline-87245627\"><span class=\"gb-icon\"><svg width=\"28\" height=\"28\" viewBox=\"0 0 28 28\" fill=\"none\"> <path d=\"M19 4H5C3.89543 4 3 4.89543 3 6V20C3 21.1046 3.89543 22 5 22H19C20.1046 22 21 21.1046 21 20V6C21 4.89543 20.1046 4 19 4Z\" stroke=\"#333\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\" fill=\"none\"><\/path> <path d=\"M16 2V6\" stroke=\"#333\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\" fill=\"none\"><\/path> <path d=\"M8 2V6\" stroke=\"#333\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\" fill=\"none\"><\/path> <path d=\"M3 10H21\" stroke=\"#333\" stroke-width=\"2\" stroke-linecap=\"round\" stroke-linejoin=\"round\" fill=\"none\"><\/path> <\/svg><\/span><span class=\"gb-headline-text\"><strong>June 24, 2025 \u2022 10:00am US Pacific<\/strong><\/span><\/div>\n\n<p style=\"font-size:16px\">Join <strong>Dr. Britta Baechler<\/strong> (Ocean Conservancy), <strong>Christy Leavitt<\/strong> (Oceana), <strong>Emily Penn<\/strong> (ocean advocate &amp; skipper), and <strong>Madeline Kaufman<\/strong> (Debris Free Oceans) on an exploration of this topic and what we can do in response.<\/p>\n<\/div><\/div>\n\n<div class=\"gb-grid-column gb-grid-column-8c5d6f76\"><div class=\"gb-container gb-container-8c5d6f76\">\n<figure class=\"gb-block-image gb-block-image-19564f23\"><a href=\"\/stories\/2025-05-08\/live-event-troubled-waters-how-microplastics-are-impacting-our-oceans-and-our-health\/\"><img loading=\"lazy\" decoding=\"async\" width=\"550\" height=\"400\" class=\"gb-image gb-image-19564f23 inset-image\" src=\"https:\/\/www.resilience.org\/wp-content\/uploads\/2025\/05\/gyre_Chris-Jordan_550w.jpg\" alt=\"Gyre by Chris Jordan\" title=\"gyre_Chris Jordan_550w\" srcset=\"https:\/\/www.resilience.org\/wp-content\/uploads\/2025\/05\/gyre_Chris-Jordan_550w.jpg 550w, https:\/\/www.resilience.org\/wp-content\/uploads\/2025\/05\/gyre_Chris-Jordan_550w-275x200.jpg 275w\" sizes=\"auto, (max-width: 550px) 100vw, 550px\" \/><\/a><\/figure>\n<\/div><\/div>\n<\/div>\n\n<a class=\"gb-button gb-button-70e07321 gb-button-text res-btn-yellow\" href=\"https:\/\/www.resilience.org\/stories\/2025-05-08\/live-event-troubled-waters-how-microplastics-are-impacting-our-oceans-and-our-health\/\">FREE REGISTRATION<\/a>\n<\/div><p>Any size and shape and color of microplastic you can dream of, it\u2019s out there, so a speck too big for one hunter becomes easy pickings for the next. Nurdles, which look just like nutritious fish eggs, may be particularly tempting. Not many marine animals are big enough to choke on a whole plastic bag, but a great many diminutive creatures can choke on microplastic they mistake for prey: lab experiments have shown that some zooplankton prefer eating aged plastics over pristine plastics by a wide margin.<sup>58<\/sup> These animals may be sniffing out the microbes they typically eat, only to instead ingest petroplankton with microbial frosting. The plastisphere, as scientists Erik Zettler and Linda Amaral-Zettler are calling it, is a new kind of microbial habitat on Earth. Moving from surface waters to deep waters and back again, from the Atlantic to the Arctic, from coral reefs to open ocean, microplastics gather miniature communities like stamps on a passport.59 \u201cBasically it\u2019s a mini-world,\u201d says Linda. \u201cThere are organisms that make their own food, that photosynthesize. There are predators there. There are prey. There are symbionts and there are pathogens as well\u2014or at least as we know them to be pathogens on animals, and potentially humans as well.\u201d Under a microscope, this mini-world bustles.<sup>60<\/sup>&nbsp;Wispy filaments, possibly produced by bacteria, wrap around kayak-shaped photosynthetic organisms known as diatoms.<sup>61<\/sup> A single-celled organism called a ciliate grows like a mushroom from the surface. Keep zooming in and you\u2019ll see it\u2019s got company: the unmistakable tubular forms of bacteria cover its bulb but\u2014more curious still\u2014not its stalk.<\/p><p>Far from being a sanitary piece of synthetic material, each microplastic crawls with life. \u201cIt\u2019s this three-dimensional structure that provides all kinds of different niches for primary producers, consumers, degraders, parasites, predators, grazers\u2014you name it,\u201d says Erik. Bacteria and viruses mingle with animals, like the larvae of barnacles. \u201cEach of those animals has its own microbiome of additional microbes that are brought to this. So it really becomes quite a complicated little community.\u201d<sup>62<\/sup>&nbsp;As these microplastics tumble around the sea, they fragment\u2014some organisms will hold on, others won\u2019t. Microbes may themselves break down the plastic: Linda and Erik have found spherical cells resting in pits on a microplastic\u2019s surface, suggesting that whatever species this is, it could be digesting the polymer. \u201cAt some point,\u201d Erik says, \u201cwhen you get down to the nanoplastics range, it\u2019s not going to be the microbe sticking to the plastic, it\u2019s going to start becoming the plastic sticking to the microbes.\u201d Erik and Linda have only begun to understand this world. They can test the DNA on microplastics to reveal what kinds of bacteria are present, but that can\u2019t tell them how those players are interacting with one another. The bacteria <em>Vibrio<\/em>, for example, has dominated many of their samples, and other researchers have found the microbe hitching rides on microplastics elsewhere, from the Baltic Sea to the coasts of China and Brazil.<sup>63<\/sup> This is the bug in undercooked seafood that can cause severe gastrointestinal distress, but Erik and Linda caution that just because <em>Vibrio <\/em>is there, often in significant quantities, doesn\u2019t necessarily mean it\u2019s a threat to the health of sea creatures or humans. What\u2019s clear, though, is that ocean life has never encountered anything quite like the plastisphere.<\/p><p>Consider the journey of a polyester microfiber. During its life on your sweater, it\u2019ll have gathered microbes from your skin and the air around you. Flushed to a wastewater treatment facility, the fiber is soaked in human waste, acquiring new microbes there.<sup>64 <\/sup>In a river, the plastisphere steeps in agricultural runoff rich in nutrients, which opportunistic microbes might thrive on.<sup>65<\/sup>&nbsp;Finally in the open ocean, the particle encounters a still more alien saltwater microbiome\u2014bacteria, viruses, animal larvae. Floating at the surface, it attracts sunlight-loving organisms,<sup>66<\/sup>&nbsp;but then grows so heavy with life that it starts sinking.<sup>67<\/sup>&nbsp;In the darkness, the microbes dependent on light will perish, happily replaced by others in the new habitat.<sup>68 <\/sup>As currents carry it dozens and hundreds and thousands of miles, our fiber will sample innumerable unique oceanic microbiomes, its own microbiomes reshuffling all the while.<sup>69<\/sup>&nbsp;It may even act as a shuttle to introduce microbes to new oceanic habitats.<\/p><p>And then, disaster\u2014mass extinction in the plastisphere. A baby crustacean hoovers up the microplastic and its hangers-on, which are now imprisoned in a hostile habitat meant to digest things. Much microbial death later, the fiber comes out the other end. \u201cThere may be a few really hardy survivors that are still left on basically pristine plastic, and it gets put out into the ocean with a little dollop of fertilizer as well,\u201d Erik Zettler says. \u201cSo all of a sudden you have this yummy piece of pristine surface with high nutrient concentration available to a whole new community. That might be very different from the community that formed when that plastic first went into the ocean.\u201d<\/p><p>Zooplankton that feed on algae could instead be filling up their bellies with microplastics <em>coated <\/em>in algae, leading to the growth of the algal blooms they normally keep in check. When these blooms die, they suck oxygen out of the water, killing off fish and other life in the area. Microplastics\u2014with their own chemicals and agglomerated pollutants\u2014 might also directly influence the proliferation of phytoplankton.<sup>70<\/sup>&nbsp;Some studies have shown that particles inhibit the growth of the tiny algae while others have shown the opposite, though these experiments were done with high concentrations of microplastics in the lab, where conditions are different than out at sea. (This is a common practice in science, generally speaking: researchers do it to elicit responses from organisms, unrealistic as the concentrations may be.<sup>71<\/sup>) But with ever more petroplankton flowing into the ocean and persisting because plastic is durable by design, microplastic concentrations will be 50 times what they are now by 2100, according to one estimate.<sup>72<\/sup>&nbsp;\u201cThe modeling predictions are suggesting that within the next 50 to 100 years, if we carry on with business as usual, then those concentrations in the environment will reach the same kinds of concentrations as we\u2019re seeing in laboratory experiments,\u201d says University of Plymouth marine biologist Richard Thompson, who coined the term <em>microplastic<\/em>. \u201cThen we\u2019ll start to see quite widespread ecological harm if we don\u2019t start to change our ways.\u201d The ripple effects could be profound.<sup>73<\/sup>&nbsp;If microplastics encourage the growth of phytoplankton, they\u2019d encourage the algae\u2019s sequestration of carbon from the atmosphere and the release of oxygen. Great for the animals on the land that breathe oxygen, but not great for fish when local water oxygen levels drop as phytoplankton die. Or instead microplastics could be discouraging the growth of phytoplankton, having the opposite effect on the cycle of carbon and oxygen in addition to shrinking a critical food source for zooplankton. (The seas have in no small part helped save humanity from itself, sequestering a third of the carbon we\u2019ve pumped into the atmosphere, so these are vital processes we\u2019re talking about.<sup>74<\/sup>) It might also be that the particles are somehow decreasing the photosynthetic efficiency of the algae, as several lab studies have suggested. Basically, scientists know that phytoplankton and petroplankton are in constant contact out there, but they don\u2019t yet know <em>how <\/em>they\u2019re interacting. The planktonic party, though, is growing increasingly crowded with microplastics\u2014that much is for sure.<\/p><ol start=\"47\" class=\"wp-block-list\"><li>Davison, Peter, and Rebecca G.
