All that glitters ain't gold, or so the old adage goes. And when it comes to the glitter used in everyday cosmetics, specialty make-up, hair products and party paraphernalia, the negative effects on human health and the environment are indeed far from golden.
"They really do get into everything, and despite their tiny size, they can have a devastating impact on humans and non-human animals," wrote Trisia Farrelly, a social anthropologist at Massey University in New Zealand and an expert in waste plastics, in an email to AlterNet.
Glitter is one member of a large family of microplastics—tiny little bits of plastic less than five millimeters in size. Think microbeads, microfibers and fingernail-sized fragments of much larger plastic wastes that have broken down over time. When washed or flushed away, microplastics make their way into our oceans and great lakes, slowly accumulating over time, creating all sorts of health and environmental hazards, the full breadth of which is still being grasped.
For one, there's the issue of how microplastics like cosmetic glitter—made by bonding aluminum with polyethylene terephthalate (PET)—impact sensitive ecosystems. That's because PETs leach out endocrine-disrupting chemicals, which, when eaten by marine life, can cause adverse developmental, reproductive, neurological and immune effects, said Farrelly. In this recent study, microplastics are shown to significantly impact the reproduction rates of oysters.
Then there's the domino-like effect of microplastics through the food-chain, for the sheer volume of microplastics consumed by seafood-loving humans is staggering. This study from the University of Ghent found that Europeans who eat shellfish can consume as much as 11,000 microplastics per year. But what are some of the long-term implications from glitter passing through the food-chain?
PETs attract and absorb persistent organic pollutants and pathogens, adding an extra layer of contamination. When those at the bottom of the ladder—like molluscs, sea snails, marine worms, and plankton—eat pathogen or pollutant-carrying particles of glitter, these minuscule poison pills can concentrate in toxicity as they move up the food chain, all the way to our dinner plates, said Farrelly.
"When we eat Kai moana [Maori term for seafood], we are taking on these toxins," she wrote. "When they enter the gut, the toxins and pathogens are very easily taken up."
A growing body of research is shining a light on the resulting effects of these toxins and pathogens on humans. Studies connect endocrine disrupting chemicals with marine and freshwater fish population collapses, as well as declines in sex ratios in human populations that live adjacent to plastic factories.
All of which is prompting many marine experts and environmentalists to advocate for the same ban on glitter as there has been on microbeads—the tiny little balls of plastic used in things like exfoliating beauty products.
"At the rate we are going, there could be one pound of plastic for every three pounds of finfish in the ocean in the next ten years," wrote Nick Mallos, director of Ocean Conservancy's Trash Free Seas Program, in an email. "And unless action is taken, the problem is only going to get bigger."
At the end of 2015 after a sustained campaign at the state level, the Obama administration signed the Microbead-Free Waters Act, banning plastic microbeads in cosmetics and personal care products. Other countries have subsequently followed suit. The U.K. and New Zealand announced their own prohibitions on microbeads earlier this year.
Importantly, these bans aren't necessarily a reflection of the singular impact from microbeads. Rather, they're a nod to a much wider understanding of the pervasiveness in the environment of microplastics in general, for the amount of microplastics entering the ocean alone is staggering. According to estimates made in 2014, there are between 15 and 51 trillion microplastic particles, weighing between 93 and 236 thousand metric tons, sitting in the world's seas.
What's more, their impacts are myriad
.A number of studies have shown that tiny plastic particles have been detected in sea salts sold commercially. In an interview with the Guardian, Sherri Mason, a professor at the State University of New York at Fredonia who led one of these studies, described plastics as being "ubiquitous in the air, water, the seafood we eat, the beer we drink, the salt we use—plastics are just everywhere." Microfibers have even been found in honey.
Microplastic had also made their way into 83 percent of tap water samples from more than a dozen countries around the world including India, Lebanon, France and Germany, according to an investigation by Orb Media. The U.S. languished at the bottom of the pile, with plastic fibers appearing in 94 percent of samples.
But microplastics comprise only a fraction of the global plastic pollution problem. The world's oceans are pockmarked, for example, with massive clusters of marine debris and plastics—the Great Pacific Garbage Patch found in the North Pacific Ocean proving to be the largest such gyre. According to the U.N., more than 8 million tons of plastic makes its way into the ocean each year—equal to a garbage truck of plastic dumped every minute.
Data shows that rapidly developing economies, where population growth and consumption are outpacing waste collection and recycling capacity, are responsible for the largest amounts of plastic wastes entering the oceans, said Nick Mallos. And he warned that, without intervention, growing economies would likely exacerbate these "unintended consequences of development spread." Still, he remains optimistic.
"By raising awareness of the issue of ocean plastic," Mallos wrote, "we can curb the flow through reduced consumption, improved waste management and innovative product and material solutions."

The conclusion to decades of work to remove a dam on the Middle Fork Nooksack River east of Bellingham, Washington began with a bang yesterday as crews breached the dam with a carefully planned detonation. This explosive denouement is also a beginning.
The History<p>The Middle Fork Nooksack drains glacier-fed headwater streams that run off the icy summit of 10,778-foot Mt. Baker. The Middle Fork joins the North Fork and then the mainstem of the Nooksack River, which travels to Bellingham Bay and Puget Sound. The entire Nooksack watershed stretches 830 square miles across Washington and into British Columbia.</p>
A Plan Comes Together<p>The Middle Fork dam is not a pool dam built for water storage. Much of the time, water flows over the top until dam operators drop a floodgate to divert water to new locations. That water travels about 14 miles through tunnel and pipeline to Mirror Lake, then Anderson Creek, and to Lake Whatcom before finally being delivered to residents' taps.</p><p>Before removing the dam, engineers had to move the water intake 700 feet upstream and situate it at an elevation that still enabled city water withdrawals throughout the year, regardless of flow conditions.</p><p>They also needed to make sure that the rushing water didn't sweep up fish and accidentally send them through the water-supply system.</p><p>"The solution required a fairly complex design in the intake structure, including a fish exit pipe out of that structure to put fish back into the river in a way that meets current environmental permit standards," explains LaCroix.</p>
Project layout for the removal of the Middle Fork Nooksack diversion dam and rebuilding of water intake. City of Bellingham<p>Despite the cost and the work, she says, being able to continue to meet their municipal water obligations while opening up habitat for threatened species has been a win-win.</p><p>"I think there's a lot of benefits to having a dam removal versus fish passage — the main one being that you get a free-flowing river that can be a dynamic ecosystem and change over time," she says. "A static fish ladder just can't provide that same level of ecosystem benefit."</p>
Restoration Success<p>Despite local authorities' championing dam removal on the Middle Fork, the project has largely flown under the radar, overshadowed in the Pacific Northwest by heated discussions about a much larger potential project — removing <a href="https://www.seattletimes.com/seattle-news/feds-reject-removal-of-4-snake-river-dams-in-key-report/" target="_blank">four federal hydroelectric dams on the lower Snake River</a>, a major tributary of the Columbia River.</p><p>Proponents of dam removal there see it as the best chance for recovering threatened salmon populations, including Chinook, which could help starving Southern Resident killer whales. Those dams also provide irrigation water, barge navigation and hydropower, so there's been more pushback against removal efforts.</p><p>Previous dam removals around the country, however, have proved successful at aiding fish recovery and river restoration.</p><p>Most notably the 1999 demolition of <a href="https://therevelator.org/edwards-dam-removal/" target="_blank">Edwards Dam on Maine's Kennebec River</a> restored the annual run of alewives, a type of herring essential to the food web. The fish run has gone from zero to 5 million in the two decades since dam removal. Blueback herring, striped bass, sturgeon and shad have also extended their reach. And the resurgence has brought back osprey, bald eagles and other wildlife, too.</p><p>The overwhelming success of river restoration on the Kennebec helped to spur a nationwide dam removal movement that's now seen 1,200 dams come down since 1999. Last year a record <a href="https://www.americanrivers.org/conservation-resource/a-record-26-states-removed-dams-in-2019/" target="_blank">90 dams</a> were removed in 26 states, including <a href="https://therevelator.org/cleveland-forest-dam-removal/" target="_blank">20 dams in California's Cleveland National Forest</a>.</p>
Spider excavators remove on dam on San Juan Creek in California's Cleveland National Forest. Julie Donnell, USFS<p>The results have been seen in the Pacific Northwest, as well, which boasts the largest dam removal thus far in the country. In 2011 and 2014, the demolition of <a href="https://therevelator.org/elwha-dam-removal/" target="_blank">two dams</a> on Elwha River, which runs through Washington's Olympic National Park, opened up 70 miles of habitat that had been blocked for a century. Scientists have started seeing all five species of salmon native to the river coming back, particularly Chinook and coho. Bull trout, they've observed, have increased in size since the dams were removal.</p>
Benefits on the Middle Fork Nooksack<p>McEwan hopes to see a similar outcome on the Middle Fork.</p><p>Like the Elwha the Middle Fork Nooksack is a relatively pristine river with little development, and dam removal is expected to provide a big boost to fish. The additional miles of spawning habitat are important, but so is the temperature of that water.</p><p>The dam removal will open access to cold upstream waters, which are ideal for salmon and getting harder to come by as climate change warms waters and reduces mountain runoff.</p><p>"This is really great for the climate change resiliency for these species," says McEwan.</p><p>Steelhead will get back 45% of their historic habitat in the river, and scientists expect Chinook populations to increase in abundance by 31%.</p><p>That <em>could</em> help Southern Resident killer whales.</p><p>"When you get to the ocean, it's a little bit of a black box in terms of what you can model and say definitively is going to help, but more fish is better for orcas," McEwan says.</p><p>Upstream habitat will see benefits, too.</p><p>Oceangoing fish like salmon enrich their bodies with carbon and nitrogen while at sea. When they return to their natal rivers to spawn and die, the marine-derived nutrients they carry back upriver become important food and fertilizer for both riverine and terrestrial ecosystems — aiding everything from trees to birds to bears.</p><p>"Once the fish start making their way back, it will start changing the whole ecological system," says Delgado.</p><p><span></span>But any ecological benefit from salmon restoration, either in the ocean or the upper watershed, won't be immediate.<br></p><p>"The population of salmon on the Middle Fork is so low that we expect it's going to take quite a while to rebound," she says. "But the big picture is that what's good for salmon is good for the region — our history and our destiny are intricately intertwined."</p><p>After decades of work, that process of restoration has finally begun.</p>

It can grow to a maximum of six inches (16 centimeters), change color depending on mood and habitat, and, like all seahorses, the White's seahorse male gestates its young. But this tiny snouted fish is under threat.
Building an Ocean Seahorse Destination<p>Seahorses are found in tropical and temperate coastal water worldwide, but are most abundant around Australia, China and the Philippines. </p><p>Trade in the tiny creatures is strictly regulated because of their use in traditional medicine, aquariums and their sale as dried curios. But because they are poor swimmers and cannot easily move elsewhere, habitat loss is a particular threat for these curious animals. </p><p>Seahorses wrap their tails around seagrass and corals to avoid being carried away on currents. They use the habitat to spawn and hide from predators such as crabs, while also feeding on riches of plankton and small crustaceans living in the reef.</p><p><span></span>Where corals aren't available, <a href="https://onlinelibrary.wiley.com/doi/abs/10.1002/aqc.1217" target="_blank">scientists</a> found seahorses taking up residence in fishing nets and old crab traps abandoned at the bottom of the ocean. </p>
Mixing With the Locals<p>Baby seahorse mortality is high in the wild because they are easily caught, so those bred in the protected environment of the aquarium weren't ready to be released into the wild until early May.</p><p>The team released 90 new arrivals into Sydney Harbor, placing some directly into the purpose-built hotels, and others onto a net that wild seahorses had already settled on.</p><p>Before setting them free, the researchers marked each young seahorse with a fluorescent tag with unique IDs inserted just beneath the skin to track how they get on in the different environments. </p><p>"The most exciting part was being able to put these animals into the wild and then go back a month later and still see them surviving and growing," said McCracken. </p><p>The seahorses will be old enough to mate and reproduce around October or November 2020. And researchers hope that by then, they will be able to breed with the wild population. </p>
Building a Global Seahorse Hotel Chain<p>With seahorses everywhere facing the loss of their coral reef homes, similar projects have sprung up in places like Greece and South Africa, home to the world's most endangered seahorse, the Knysna seahorse. </p><p>"The endangered South African seahorse is benefiting from something quite similar, even though it wasn't intentional," said Peter Teske, professor at the Department of Zoology, University of Johannesburg.</p><p>In the South African <a href="https://www.researchgate.net/publication/322649251_An_endangered_seahorse_selectively_chooses_an_artificial_structure" target="_blank">case</a>, seahorses have bedded down in "Reno mattresses" — wire cages filled with rocks — that were used to build a new marina. Researchers from NGO Knysna Basin Project found the structures acted as a refuge for the animals.<span></span></p><p><span></span>While Teske describes the seahorse hotels as "a positive news story" and a great way to create public awareness of conservation, he added that establishing artificial habitats in some areas will only prevent the extinction of local populations.</p><p>"For a complete recovery, it is necessary to give the natural habitat a chance to regenerate," said the seahorse expert. </p>
Underwater Mascot<p>In Australia, the researchers hope the project could provide an opportunity to raise awareness not only of the plight of the Sydney seahorses but the other animals with which it shares its ocean habitat.</p><p>The waters around Sydney and the east coast are rich in biodiversity and include several threatened species like the weedy seadragon — a relative of the seahorse — and the grey nurse shark. Like the seahorse, they're also under pressure from pollution, ocean traffic and habitat loss through storms and coastal construction. </p><p>"It's a good thing to get people's support and interest. The seahorses are a useful vehicle to get people concerned if the harbor is in trouble," said David Booth, professor of marine ecology at the University of Technology Sydney who is also working on the project. </p><p>The hotels have become an attraction for divers hoping to catch a glimpse of these small but near mythical creatures. </p><p>"Everyone loves seahorses," added Booth, "they are so popular." </p>
