Hudson River Dumps 300 Million Microfibers Into Atlantic Ocean Daily

A new study highlights how our laundry contributes to major oceanic pollution.
The Hudson River could be dumping about 300 million clothing fibers into the Atlantic Ocean per day, according to new research published in the Marine Pollution Bulletin.
For the study, researchers collected 142 water samples throughout the length of the Hudson River and found about one microfiber per liter. That's a lot when you consider that this endless stream of human-made fibers ultimately ends up in our oceans.
"The ocean is the endgame for plastics," marine biologist Abigail Barrows, a principal investigator with Adventure Scientists, told PBS Newshour.
About half the samples were plastic microfibers and the other half were non-plastic microfibers such as cotton or wool.
Microfibers get flushed into our waterways when we wash our clothing or other textiles. Notably, the researchers did not find more fibers near wastewater treatment plants or high-population areas, suggesting that microfiber pollution is pervasive throughout the river.
"There was no pattern across the whole Hudson River—from Lake Tear of the Clouds, an alpine remote beauty, down to the heaving, thriving Manhattan," Rachael Miller, a co-author on the study, told PBS. "It was a real surprise."
You might not be able to see microfibers with the naked eye but the material is pervasive in our environment and can make its way up the food chain, according to The Story of Stuff:
"Microfibers are tiny plastic threads shed from synthetic fabrics like polyester, rayon and nylon. These fabrics currently make up 60 percent of all clothing worldwide and their use as the dominant textile materials [is] dramatically on the rise. When washed, plastic microfibers break off and a single jacket can produce up to 250,000 fibers in washing machine effluent. Less than 1 mm in size, they ultimately make their way through wastewater plants and into marine environments where they have been found to enter the food chain. Microfibers make up 85 percent of human made debris on shorelines around the world according to a 2011 study."
Barrows told PBS she wears wool or other natural materials to reduce her plastic footprint, but even natural materials can be harmful to the environment.
"Toxins and dyes are added into that thread. The science is still out. We don't know how natural fibers are interacting with humans or animals," she said.
Heatwaves are not just distinct to the land. A recent study found lakes are susceptible to temperature rise too, causing "lake heatwaves," The Independent reported.

A chance discovery of a beautifully preserved fossil in the desert landscape of Morocco has solved one of the great mysteries of biology and paleontology: how starfish evolved their arms.

<h2></h2><p>Although starfish might appear very robust animals, they are typically made up of lots of hard parts attached by ligaments and soft tissue which, upon death, quickly degrade. This means we rely on places like the Fezouata formations to provide snapshots of their evolution.</p><p>The starfish fossil record is patchy, especially at the critical time when many of these animal groups first appeared. Sorting out how each of the various types of ancient starfish relate to each other is like putting a puzzle together when many of the parts are missing.</p><h2>The Oldest Starfish</h2><p><em><a href="https://www.biorxiv.org/content/10.1101/216101v1.full.pdf" target="_blank" rel="noopener noreferrer">Cantabrigiaster</a></em> is the most primitive starfish-like animal to be discovered in the fossil record. It was discovered in 2003, but it has taken over 17 years to work out its true significance.</p><p>What makes <em>Cantabrigiaster</em> unique is that it lacks almost all the characteristics we find in brittle stars and starfish.</p><p>Starfish and brittle stars belong to the family Asterozoa. Their ancestors, the Somasteroids were especially fragile - before <em>Cantabrigiaster</em> we only had a handful of specimens. The celebrated Moroccan paleontologist Mohamed <a href="https://doi.org/10.1016/j.palaeo.2016.06.041" target="_blank" rel="noopener noreferrer">Ben Moula</a> and his local team was instrumental in discovering <a href="https://www.sciencedirect.com/science/article/abs/pii/S0031018216302334?via%3Dihub" target="_blank" rel="noopener noreferrer">these amazing fossils</a> near the town of Zagora, in Morocco.</p><h2>The Breakthrough</h2><p>Our breakthrough moment came when I compared the arms of <em>Cantabrigiaster</em> with those of modern sea lilles, filter feeders with long feathery arms that tend to be attached to the sea floor by a stem or stalk.</p><p>The striking similarity between these modern filter feeders and the ancient starfish led our team from the University of Cambridge and Harvard University to create a new analysis. We applied a biological model to the features of all the current early Asterozoa fossils in existence, along with a sample of their closest relatives.</p>Cantabrigiaster is the most primitive starfish-like animal to be discovered in the fossil record.

<p>Our results demonstrate <em>Cantabrigiaster</em> is the most primitive of all the Asterozoa, and most likely evolved from ancient animals called crinoids that lived 250 million years before dinosaurs. The five arms of starfish are a relic left over from these ancestors. In the case of <em>Cantabrigiaster</em>, and its starfish descendants, it evolved by flipping upside-down so its arms are face down on the sediment to feed.</p><p>Although we sampled a relatively small numbers of those ancestors, one of the unexpected outcomes was it provided an idea of how they could be related to each other. Paleontologists studying echinoderms are often lost in detail as all the different groups are so radically different from each other, so it is hard to tell which evolved first.</p>Trending

In many schools, the study of climate change is limited to the science. But at the University of Minnesota, Twin Cities, students in one class also learn how to take climate action.

Industry would have us believe that pesticides help sustain food production — a necessary chemical trade-off for keeping harmful bugs at bay and ensuring we have enough to eat. But the data often tell a different story—particularly in the case of neonicotinoid pesticides, also known as neonics.
