Microplastics pose a huge threat to aquatic life, particularly large filter feeders such as whale sharks, manta rays, and baleen whales . A new study by an international team of researchers led by the Marine Megafauna Foundation (MMF) and Murdoch University identifies risks faced by these marine giants from an insidious form of plastic pollution known as microplastics. Filter feeders are at particular risk because of their constant sifting through ocean water to capture their micro-plankton prey. These large creatures play an important role in oceanic ecosystems and huge problems in the food chain could arise if they were to become threatened or even extinct due to escalating threats. While much remains unknown about the specific impacts of ingesting microplastics, evidence suggests that plastic ingestion, whether directly or through eating animals that have consumed plastics, can lead to toxicity in fish and birds. The effects on large, filter feeders is even less understood, a knowledge gap that the study authors urgently sought to address. “Understanding the effects of microplastic pollution on filter-feeding megafauna is imperative because nearly half of the mobulid rays, two-thirds of filter-feeding sharks , and over one quarter of baleen whales are listed by the IUCN as globally threatened species and prioritized for conservation,” wrote the study authors . Related: Over 200 nations commit to ending ocean plastic waste Incorporating a review of data from related research, the new study identifies microplastic “hotspots,” such as the Gulf of Mexico, the Bay of Bengal, the Coral Triangle, and the Mediterranean Sea , as areas where filter feeders gather in high numbers likely due to plentiful food sources. This unfortunate confluence of plankton and plastic pollution has led to filter feeders consuming significant amounts of microplastics, with fin whales estimated to consume up to 2,000 plastic particles per day. While a greater understanding of the problem is helpful, this new research also emphasizes the sorely needed action needed to prevent further harm from plastic pollution to ocean life, large and small.

"Microplastics have been found in mussels everywhere scientists have looked"

Mussels might serve as a global “bioindicator of microplastic pollution ,” Chinese researchers suggested last year, as the creatures remain in the same area and reside on the seabed where plastic ends up. And a new study from the Norwegian Institute for Water Research (NIVA) uncovered plastic in 76.6 percent of individual blue mussels they tested. Reuters pointed to other surveys where researchers found microplastics in mussels near China, Belgium, Britain, Canada, and Chile. NIVA Researcher Amy Lusher told Reuters, “Microplastics have been found in mussels everywhere scientists have looked.” The new NIVA research found on average 1.8 pieces of microplastic in mollusks near Norway, while and mussels living in waters thought to be pristine in the Arctic actually had the greatest amount of plastic among any of the creatures tested near the Norwegian coast. Lusher said ocean currents and winds from American and Europe may be sweeping plastic north, where it might then swirl in the Arctic Ocean.

Microplastics expert and Plymouth University professor Richard Thompson told Reuters of the global discoveries, “It’s a warning signal that we need to do something about reducing the input of plastic to the ocean. It’s a cause for concern at the moment rather than an alarm story for human consumption.” You can check out the NIVA report here .

Scientists call for a worldwide ban on the ‘global hazard’ of glitter

You know microbeads are terrible for the planet, but have you ever considered the environmental impact of glitter? The ubiquitous party supply is made up of tiny plastic particles , and are every bit as bad as microbeads, which have been banned in many places across the world. Now, scientists say that it’s time to ban the glittery stuff as well. Microplastics make their way from waterways and landfills into the ocean, where sea life consumes it. Fish have been found to actively seeking out plastics , mistaking it for food, and a third of fish in the UK contain plastics. This is not only deadly for wildlife, but it could be dangerous for humans who consume fish as well. Related: Microplastics are killing fish faster than they can reproduce Glitter has become more and more common, appearing in cosmetics , clothing, and bath products, (not to mention the trend of putting on beards and hair) in addition to the party supply aisle. Scientists say that it should be treated like microbeads since it is essentially no different when it comes to the environment, and are calling for a ban.

Designer Antony Gibbon is known for his nature-inspired designs , each of which is more jaw-dropping than the last. His latest masterpiece is the Helix House – a beautiful twisting tower clad in wooden slatted beams that seamlessly blends into the forest. At just 100 square feet, the home is tiny, but the majestic design is straight out of a fairy tale. Like all of Gibbons’ designs, the Helix House was inspired by nature. The rising twisted form allows the structure blend in quietly with the surrounding forestscape. Clad in wooden beams, the home’s design is not only gorgeous, but the unique shape was also strategic to hiding all the structural support and access into the low-impact home. Related:Antony Gibbon’s Lucent House is a serene minimalist retreat made of glass and stone A tiny home in tower form, the one-bedroom home is less than 100 square feet. On the inside, the first floor has a kitchenette and a small bathroom. The second floor houses the bedroom, which has a beautiful glazed wall that provides natural light and stellar views of the surrounding environment. + Antony Gibbon Designs Images via Antony Gibbon Designs

Now There’s Microplastic Pollution in the Great Lakes Too

Plastic pollution on Bicaz Lake in Romania for illustrative purposes only, Shutterstock Swirling plastic pools as large as countries have long collected in our oceans , but now researchers have found that the Great Lakes face a similar problem, Discovery reports. While on a recent outing with students, environmental chemist Sherri Mason wondered whether plastic might be floating in the world’s largest freshwater system, so she and other researchers returned with a large trawl and a mesh net that traps anything larger than one third of a millimeter. They took 21 samples from Lakes Superior, Erie and Huron, which revealed that in some places there are up to 650,000 bits of plastic in a square kilometer.
