A high-altitude clean-up in Bolivia’s Valley of the Souls

In Bolivia’s Valley of the Souls, razor sharp rock formations pierce the blue sky above the nearby highland city of La Paz, from where urban sprawl over years has left the picturesque spot littered with plastic waste and construction rubble.

Now the rocky canyon is getting a clean up amid a wider push to spruce up the South American country’s scenic spots and waterways, with hundreds of volunteers, aided by heavy machinery, shifting over 15 tons of debris in the last week.

Why 99% of ocean plastic pollution is “missing”

by

via Vox

Starting in the 1990s, the world’s attention began turning to the specter of ocean garbage patches — heaps of plastic and other debris that accumulate in distinct areas of the ocean, thanks to currents known as gyres. These patches came to symbolize our global addiction to plastic production and consumption.

A lot of the plastic we consume ends up in the ocean due to man-made causes, such as poor waste management practices. Some of it ends up there because of natural disasters. There’s a lot of Japanese plastic floating in the Great Pacific Garbage Patch, for example, due to the 2011 tsunami. Japan is a country that otherwise has above-average waste management policies.

This 185-foot sailboat can gobble up to three tons of plastic waste per hour

According to the International Union for Conservation of Nature, at least eight million tons of plastic end up in our oceans every year and make up 80 percent of all marine debris from surface waters to deep-sea sediments. If nothing is done about the situation, there will be more plastic waste in the oceans than fish by 2050. French ocean adventurer Yvan Bourgnon and his team have therefore taken it upon themselves to heal the ocean slowly but surely. They’ve designed Manta, a 185-foot, plastic-eating catamaran (sailboat) powered by renewable energy. Plastic trash is literally scooped up and converted into fuel to help power the catamaran.

Could Plastic-Eating Mushrooms Solve Humanity’s Plastic Problem?

by

via Interesting Engineering

Since the mass production of plastics began in the 1950s, humans have created 9 billion tons of plastic, and this creates a crisis that’s not easy to tackle since plastic takes more than 400 years to degrade. Those used by the people of the ’60s still exist in some form, and with only 9 percent recycled, only 12 percent has been incinerated.

This has lead scientists to search for alternative methods for plastic reduction, and one solution that could aid humanity might be hidden in fungi. Scientists have discovered mushrooms that eat plastic over the years: Some mushroom species have the ability to consume polyurethane, which is one of the main ingredients in plastic products.

Airborne plastic pollution ‘spiralling around the globe’, study finds

by

via The Guardian

Microplastic pollution is now “spiralling around the globe”, according to a study of airborne plastic particles.

The researchers said human pollution has led to a global plastic cycle, akin to natural processes such as the carbon cycle, with plastic moving through the atmosphere, oceans and land. The result is the “plastification” of the planet, said one scientist.

Plastic Is Falling From the Sky. But Where’s It Coming From?

by

via Wired

At any given time, 1,100 tons of microplastic are floating over the western US. New modeling shows the surprising sources of the nefarious pollutant.

IF YOU FIND yourself in some secluded spot in the American West—maybe Yellowstone, or the deserts of Utah, or the forests of Oregon—take a deep breath and get some fresh air along with some microplastic. According to new modeling, 1,100 tons of it is currently floating above the western US. The stuff is falling out of the sky, tainting the most remote corners of North America—and the world. As I’ve said before, plastic rain is the new acid rain.

But where is it all coming from? You’d think it’d be arising from nearby cities—western metropolises like Denver and Salt Lake City. But new modeling published yesterday in the Proceedings of the National Academy of Sciences shows that 84 percent of airborne microplastics in the American West actually comes from the roads outside of major cities. Another 11 percent could be blowing all the way in from the ocean. (The researchers who built the model reckon that microplastic particles stay airborne for nearly a week, and that’s more than enough time for them to cross continents and oceans.)

How does plastic debris make its way into ocean garbage patches?

by

via EurekAlert

WASHINGTON, March 2, 2021 — Tons of plastic debris get released into the ocean every day, and most of it accumulates within the middle of garbage patches, which tend to float on the oceans’ surface in the center of each of their regions. The most infamous one, known as the Great Pacific Garbage Patch, is in the North Pacific Ocean.

Researchers in the U.S. and Germany decided to explore which pathways transport debris from the coasts to the middle of the oceans, as well as the relative strengths of different subtropical gyres in the oceans and how they influence long-term accumulation of debris.

It’s not just oceans: scientists find plastic is also polluting the air

For several years scientists were puzzled why Delhi was more susceptible to thick smogs than other polluted cities such as Beijing. New research links this to tiny chloride particles in the air that help water droplets to form. Globally, chloride particles are mainly found close to coasts, due to sea spray, but the air in Delhi and over inland India contains much more than expected.

At first, the sources were thought to be illegal factory units around Delhi that recycle electronics and those that use strong hydrochloric acid to clean and process metals. These are certainly part of the problem, but new measurements have revealed another source.

Sea turtle: Sentinels and victims of plastic pollution in the Adriatic Sea

by

via EurakAlert

Sea turtles are witnesses and victims of the high level of plastic pollution of the Adriatic Sea. A group of researchers at the University of Bologna analysed 45 turtles hospitalised at Fondazione Cetacea in Riccione and found plastic debris in their faeces. Besides confirming the role of turtles as ideal sentinels to monitor plastic pollution in the sea, the results of their analysis – published in the journal Frontiers of Marine Medicine – crucially show how the plastic debris in their intestines can dangerously alter their microbiota, eventually compromising their health.

Fighting the plastics plague, one canoe-full at a time

John Naylor eased his 16-foot fiberglass canoe into the Susquehanna River near a small archipelago of forested and ever-changing mudflat islands known as the Conejohela Flats, once the domain of Native Americans and still a vital stop for migrating shorebirds.

It’s a placid and beautiful spot on the lower Susquehanna between Lancaster and York counties, PA. But the York city resident was there this day to nibble at a growing sheen of ugliness — namely, single-use plastic containers, especially discarded water bottles.
