Over two three-month periods, researchers sampled air quality at five sites along metro Atlanta interstates and highways. When compared to similar sites without vegetation, the researchers found a 37% reduction in soot and a 7% reduction in ultrafine particles at sites with natural or ornamental vegetation. The findings appear in the journal PLOS ONE. “Trees and bushes near roadways don’t solve the problem of air pollution caused by motor vehicles, but they can help reduce the severity of the problem,” says lead author Roby Greenwald, associate professor in the Georgia State University School of Public Health.

““The Great Pacific Garbage Patch can now be cleaned,” announced Dutch entrepreneur Boyan Slat, the wonderkid inventor who’s spent a decade inventing systems for waterborne litter collection.
Recent tests on his Ocean Cleanup rig called System 002, invented to tackle the 1.8 trillion pieces of plastic pollution, were a success, leading Slat to predict that most of the oceanic garbage patches could be removed by 2040.
Intersections of ocean currents have created the massive floating islands of plastic trash—five slow-moving whirlpools that pull litter from thousands of miles away into a single radius.
The largest one sits between California and Hawaii, and 27-year-old Slat has been designing and testing his systems out there, launching from San Francisco since 2013.
GNN has reported on his original design for the floating device, but his engineering team improved upon it. System 002, nicknamed “Jenny,” successfully netted 9,000 kilograms, or around 20,000 pounds in its first trial.
It’s carbon-neutral, able to capture microplastics as small as 1 millimeter in diameter, and was designed to pose absolutely no threat to wildlife thanks to its wide capture area, slow motion, alerts, and camera monitors that allow operators to spy any overly-curious marine life...
Slat estimates ten Jennies could clean half the garbage patch in five years, and if 10 Jennies were deployed to the five major ocean gyres, then 90% of all floating plastic could be removed by 2040.” -via Good News Network, 10/19/21

Welcome to my Tuesday morning PSA about plastics!
So--I was walking along the Bolstadt beach approach sidewalk here in Long Beach, WA yesterday afternoon, and I started seeing these little orange pellets on the ground that looked a little bit like salmon roe (but probably weren't). So I picked one up, and it was most definitely rubber. I went around picking up every one I could find, and while I didn't keep exact count I probably amassed 50-60 of them. I took this picture before depositing them in the nearest trash can.
These are airsoft gun pellets, and you can buy them in big jars containing thousands of them. That means that someone who decided that the beach was a great place to shoot their airsoft guns could easily litter the place with countless little bits of plastic rubber in less than an hour. We already have a huge problem here with people leaving trash, including tiny bits of plastic, all over the beach (you should see the gigantic mess after 4th of July fireworks when thousands of people come in from out of town, blow things up, and then leave again without picking up after themselves.)
But these airsoft pellets have a particularly nasty side effect. You know how my first thought was "wow, those look kind of like salmon roe?" Well, we have a number of opportunistic omnivore birds like crows, ravens, and several species of gull that commonly scavenge on the beach, especially along the approaches because people often feed them there. If I can catch the resemblance of an orange airsoft pellet to a fish egg, then chances are there are wildlife that will assume they're edible.
Since birds don't chew their food, they probably won't notice that the taste or texture is wrong--it'll just go down the hatch. And since they can't digest the pellets, there's a good chance they might just build up in the bird's digestive system, especially if the bird eats a large number of them--say, fifty or sixty of them dropped on the ground along the same fifty foot stretch of sidewalk. The bird might die of starvation if there's not enough capacity for food in their stomach--or they might just die painfully of an impacted gut, and no way to get help for it. If the pellets end up washed into the ocean, you get the same issue with fish and other marine wildlife eating them, and then of course the pellets eventually breaking up into microplastic particles.
You can get biodegradable airsoft pellets; they appear to mainly be gray or white in color rather than bright screaming orange and green. But "biodegradable" doesn't mean "instantly dissolves the next time it rains." An Amazon listing for Aim Green biodegradable airsoft pellets advertise them as "Our biodegradable BBs are engineered to degrade only with long-term exposure to water and sun and will degrade 180 days after being used." That's half a year for them to be eaten by wildlife.
I don't know, y'all. That handful of carelessly dropped rubber pellets just encapsulates how much people don't factor in the rest of nature when making decisions, even on something that is purely for entertainment like an airsoft gun. We could have had a lot of the same technological advances we have today, but with much less environmental impact, if we had considered the long-term effects on both other people and other living beings, as well as our habitats. We could have found ways from the beginning to make these things in ways that benefited us but also mitigated any harm as much as possible. Instead we're now having to reverse-engineer things we've been using for decades, and sometimes--like the "biodegradable" airsoft pellets--they still have a significant negative impact.
But--at least there are people trying to do things better, thinking ahead instead of just on immediate profit. We're stuck in a heck of a mess here, figuratively and literally, and changing an entire system can't be done in a day. Maybe we can at least keep pushing for a cultural shift that emphasizes planning far into the future--if not the often-cited "seven generations ahead", then at least throughout the potential lifespan of a given product.

Analysis of data gathered using cutting-edge methodology – including detailed satellite images and measurements from more than 1,400 ground monitoring stations – reveals a dire picture of dirty air, with 98% of people living in areas with highly damaging fine particulate pollution that exceed World Health Organization guidelines. Almost two-thirds live in areas where air quality is more than double the WHO’s guidelines.
[...]
“This is a severe public health crisis,” said Roel Vermeulen, a professor of environmental epidemiology at Utrecht University who led the team of researchers across the continent that compiled the data. “What we see quite clearly is that nearly everyone in Europe is breathing unhealthy air.”

"At nearly 150 acres, the Jardim Gramacho landfill in Rio de Janeiro was one of the largest and most infamous in all of Latin America. Now it’s a mangrove forest teeming with life.
Decommissioned 11 years ago, between 1970 and 2012 the dump, bordering Rio’s famous Guanabara Bay, received 80 million metric tonnes of trash from the area’s Gramacho neighborhood.
Now, a public-private partnership led by the Rio Municipal Cleaning Company has returned the area to nature, specifically mangroves, one of the most valuable of all ecosystems.
Planting 24 acres of mangroves at a time, today the forest stretches out more than 120 acres and is the largest mangrove area of the bay.
“Before, we polluted the bay and the rivers. Now, it’s the bay and the rivers that pollute us,” a lead official on the project told Africa News. “Today, the mangrove has completely recovered.”
Other organizations have taken action to restore mangroves along the bay as well. The non-profit Ocean Pact funded the Green Guanabara Bay Project which successfully restored 12.5 hectares or around 25 acres of mangroves.
According to some estimates, 1 acre of mangrove forests can store more carbon in roots and soil than 4 acres of even the most biodiverse rainforest, making them paramount to any world climate mitigation strategy.
Furthermore, their impressive lattice work of roots and insane durability means that storm surges impacting mangroves lose about 66% of their kinetic energy without even destroying the trees.
Lastly, coastal fishing communities, in [four] words, cannot exist without mangroves. They act as nurseries and perfect habitat for all kinds of fish and crustaceans that small-scale fishermen rely on for their daily bread."

of fucking course.....they fucking coated paper straws with pfas......its a fucking nightmare
--
Long-lasting 'forever chemicals', which can cause damaging health issues, found in 18/20 brands of paper straws
In the first analysis of its kind in Europe, and only the second in the world, Belgian researchers tested 39 brands of straws for the group of synthetic chemicals known as poly- and perfluoroalkyl substances (PFAS).
PFAS were found in the majority of the straws tested and were most common in those made from paper and bamboo, the study, published in the peer-reviewed journal Food Additives and Contaminants, found.
PFAS are used to make everyday products, from outdoor clothing to non-stick pans, resistant to water, heat and stains. They are, however, potentially harmful to people, wildlife and the environment.
They break down very slowly over time and can persist over thousands of years in the environment, a property that has led to them being known as "forever chemicals."
They have been associated with a number of health problems, including lower response to vaccines, lower birth weight, thyroid disease, increased cholesterol levels, liver damage, kidney cancer and testicular cancer.
"Straws made from plant-based materials, such as paper and bamboo, are often advertised as being more sustainable and eco-friendly than those made from plastic," says researcher Dr Thimo Groffen, an environmental scientist at the University of Antwerp, who is involved in this study.
"However, the presence of PFAS in these straws means that's not necessarily true."
A growing number of countries, including the UK and Belgium, have banned sale of single-use plastic products, including drinking straws, and plant-based versions have become popular alternatives.
A recent study found PFAS in plant-based drinking straws in the US. Dr Groffen and colleagues wanted to find out if the same was true of those on sale in Belgium.
To explore this further, the research team purchased 39 different brands of drinking straw made from five materials -- paper, bamboo, glass, stainless steel and plastic.
The straws, which were mainly obtained from shops, supermarkets and fast-food restaurants, then underwent two rounds of testing for PFAS.
The majority of the brands (27/39, 69%) contained PFAS, with 18 different PFAS detected in total.
The paper straws were most likely to contain PFAS, with the chemicals detected in 18/20 (90%) of the brands tested. PFAS were also detected in 4/5 (80%) brands of bamboo straw, 3/4 (75%) of the plastic straw brands and 2/5 (40%) brands of glass straw. They were not detected in any of the five types of steel straw tested.
The most commonly found PFAS, perfluorooctanoic acid (PFOA), has been banned globally since 2020.
Also detected were trifluoroacetic acid (TFA) and trifluoromethanesulfonic acid (TFMS), "ultra-short chain" PFAS which are highly water soluble and so might leach out of straws into drinks.
The PFAS concentrations were low and, bearing in mind that most people tend to only use straws occasionally, pose a limited risk to human health. However, PFAS can remain in the body for many years and concentrations can build up over time.
"Small amounts of PFAS, while not harmful in themselves, can add to the chemical load already present in the body," says Dr Groffen.
It isn't known whether the PFAS were added to the straws by the manufacturers for waterproofing or whether were the result of contamination. Potential sources of contamination include the soil the plant-based materials were grown in and the water used in the manufacturing process.
However, the presence of the chemicals in almost every brand of paper straw means it is likely that it was, in some cases, being used as a water-repellent coating, say the researchers.
The study's other limitations include not looking at whether the PFAS would leach out of the straws into liquids.
Dr Groffen concludes: "The presence of PFAS in paper and bamboo straws shows they are not necessarily biodegradable.
"We did not detect any PFAS in stainless steel straws, so I would advise consumers to use this type of straw -- or just avoid using straws at all."
