Algorithms Aid Tracking of Migrating Songbirds in Arctic

Tracking wildlife migration has been historically difficult in the rugged terrain of Alaska. Researchers primarily rely on either surveys or GPS tracking to understand bird migration patterns. Both methods are expensive, either in terms of time or money. And the trackers are often too large or heavy. 

One way to sidestep these common issues is to record audio from frequently used nesting grounds. Using birdsong allows researchers to unobtrusively study the animals, although there’s a downside. Each day produces a flood of audio recordings from multiple microphones placed around nesting grounds. It takes trained listeners endless hours to search the noisy soundscape for birdsong.

In a recently published paper in the journal Science Advances, U.S. researchers explain how they got around these tracking troubles. Columbia University ecologist Ruth Oliver and her fellow collaborators replaced the human ears with machine learning algorithms to listen to birdsong.

Costly proposition

Oliver told VOA News, “Arrival times of migratory song birds is really important for their reproductive success. And obviously sending people to the Arctic to do field work is very expensive and takes a lot of time” — hence, the scientists’ interest in creating an automated method for tracking bird species.

Oliver and her colleagues focused on migratory songbirds who fly to northern Alaska during their mating season. These birds tend to chirp more frequently as soon as they reach the breeding grounds to attract a mate. Spring is short in Alaska and the birds must breed and hatch their clutch before winter.

The team of researchers recorded the springtime soundscape of northern Alaska for five sequential years. They placed microphones at four sites in the foothills of the Brooks Range, which recorded 1,200 audio hours.

However, Oliver admitted the recordings weren’t always perfect. “There’s a lot of other noise in these recordings” Oliver said. “Even in May in northern Alaska there’s lots of wind, lots of rain, and all of that is confounding when you’re listening to birds.”

The scientists fed hours of audio into two types of machine learning algorithms — one that used human expertise to help train it and one that relied solely on the collected audio. Both algorithms were based on the same model that’s used by applications like Siri and Alexa.

Oliver told VOA that in creating the human-supervised algorithm, she “wrote a little program to randomly sample about 1 percent of the data set” and then listened to 4-second clips. She scored these clips as either containing or not containing songbird vocalizations and then fed this information into the program.

Both algorithms were fairly accurate at estimating when the avian commuters arrived in the foothills. The models showed the importance of snowmelt for the arrival of the traveling birds. The human-trained model was slightly better at recognizing the relationship between weather conditions and bird calls, although neither model specifically tracked individual species.

This technique has great potential according to Emily Jo Williams, vice president of migratory birds and habitat at the American Bird Conservancy, “This kind of technique that allows you to survey populations in those remote areas is really exciting and could allow us to even discover new places where protection and conservation efforts are needed,” she said.

This study looked at nesting grounds near the Alaskan Arctic Refuge, which is a summer home for birds from nearly every continent. For example, the Northern Wheatear travels approximately 21,000 kilometers (13,000 miles) from Africa to summer in the refuge.

Climate change

Williams told VOA, “We know from some research that some birds’ ranges have actually changed, and they’ve moved in response to what we think is a warming climate.” She went on to explain that “the timing of that migration has evolved over eons, and in large part it’s relative to what food sources are available over a particular time, what weather patterns are or aren’t favorable. So you could end up with bird migration out of sync with insect hatches or the phenology of plants that birds have a relationship to.”

Tools like the algorithm created in this study could be used to track how migratory patterns of many species may shift in response to climate change. Using machine learning is a new way to follow these shifting patterns in birds, insects and other animals.

French Divided Over Bataclan Performances by Rapper Medine

“All I want to do is the Bataclan, the Bataclan.” Those are lyrics to a song released earlier in the year by rapper Medine. Two of his concerts are scheduled for the Bataclan theater in October. But not everyone wants to see the shows go on.

At issue, in part, are the words to another song by the artist, whose real name is Medine Zaouiche. In the song, “Don’t Laik,” one line goes, “I put fatwas on the heads of idiots.” The song was released in 2015 — the same year that France was hit by several terrorist attacks, including one targeting the Bataclan.

This is not the first time Medina has generated controversy. A decade earlier, he released an album titled Jihad — and he has been photographed in a T-shirt bearing the term, and a massive sword.

Now, thousands of people have signed a petition launched by the far right and demanding Medine’s concerts be canceled. Critics are tweeting their opposition via the hashtag #pasdemedineaubataclan, or “no Medine at the Bataclan.”

On French radio, far-right National Rally party head Marine Le Pen described Medine as an Islamic fundamentalist. His performance at the Bataclan, she said, is a threat to public order.

Victims’ associations are divided. Philippe Duperron, who heads one of them, is against the concerts taking place, out of respect for the victims and the memory of them.

Medine and his lawyers are fighting back. The rapper has criticized Islamic fundamentalism a number of times and says he is against violence. He says “Don’t Laik” is more of a slap at France’s tough secular creed, and that the jihad he refers to is an internal spiritual struggle, rather than violence.

“It’s been 15 years since I’ve criticized all forms of radicalism in my albums,” he posted recently on social media. Banning his concerts, he argues, amounts to caving in to the far right.

Medine’s arguments are drawing support, partly in the name of free expression. That appears to be the argument of Prime Minister Edouard Philippe. 

Still, others argue the divisions over the rapper’s concerts are the worst outcome, at a time when the French should be united against terrorism.

Police: Backup Driver in Fatal Uber Crash Was Distracted

The human backup driver in an autonomous Uber SUV was streaming the television show “The Voice” on her phone and looking downward just before fatally striking a pedestrian in suburban Phoenix, according to a police report.

The 300-page report released Thursday night by police in Tempe revealed that driver Rafaela Vasquez had been streaming the musical talent show via Hulu in the 43 minutes before the March 18 crash that killed Elaine Herzberg as she crossed a darkened road outside the lines of a crosswalk. The report said the crash, which marks the first fatality involving a self-driving vehicle, wouldn’t have happened had the driver not been distracted.

Dash camera video shows Vasquez was looking down near her right knee for four or five seconds before the crash. She looked up a half second before striking Herzberg as the Volvo was traveling about 44 miles per hour.

Vasquez told police Herzberg “came out of nowhere” and that she didn’t see her prior to the collision. But officers calculated that had Vasquez been paying attention, she could have reacted 143 feet before impact and brought the SUV to a stop about 42.6 feet before hitting Herzberg.

“This crash would not have occurred if Vasquez would have been monitoring the vehicle and roadway conditions and was not distracted,” the report stated.

Tempe police are looking at a vehicular manslaughter charge in the crash, according to a March 19 affidavit filed to get a search warrant for audio, video and data stored in the Uber SUV.

 

 The detective seeking the warrant, identified as J. Barutha, wrote that based on information from the vehicular homicide unit, “it is believed that the crime of vehicular manslaughter has occurred and that evidence of this offense is currently located in a 2017 Grey Volvo XC-90.”

A previously released video of the crash showed Vasquez looking down just before the crash. She had a startled look on her face about the time of the impact.

The National Transportation Safety Board, in a preliminary report issued last month, said the autonomous driving system on Uber’s Volvo XC-90 SUV spotted Herzberg about six seconds before hitting her, but did not stop because the system used to automatically apply brakes in potentially dangerous situations had been disabled.

The system is disabled while Uber’s cars are under computer control, “to reduce the potential for erratic vehicle behavior,” the NTSB report said. Instead of the system, Uber relies on the human backup driver to intervene, the report stated. But the system is not designed to alert the driver.

Uber pulled its self-driving cars out of Arizona the day before the NTSB report was released, eliminating the jobs of about 300 people who served as backup drivers and performed other jobs connected to the vehicles. The company had suspended testing of its self-driving vehicles in Arizona, Pittsburgh, San Francisco and Toronto while regulators investigated the cause of the crash. Arizona Gov. Doug Ducey prohibited Uber from continuing its tests of self-driving cars after Herzberg was run over.

Police initially determined that Vasquez was not impaired after giving her a field test.

Analysis of video taken from the vehicle shows Vasquez looked downward 204 times in the 11.8 miles traveled before the crash. While the SUV was in motion, Vasquez averted her eyes away from the roadway nearly a third of the time, according to the report.

“Sometimes, her face appears to react and show a smirk or laugh at various points during the times that she is looking down,” the report said. “Her hands are not visible in the frame of the video during these times.”

The office of Cristina Perez Hesano, an attorney for Herzberg’s daughter and husband, declined to comment on the police report. Attorney Pat McGroder, who represents Herzberg’s mother, father and son, didn’t immediately respond to a call late Friday morning seeking comment.

An Uber spokeswoman said in a prepared statement Friday morning that the company is cooperating with investigations while it does an internal safety review. “We have a strict policy prohibiting mobile device usage for anyone operating our self-driving vehicles. We plan to share more on the changes we’ll make to our program soon,” the statement said.

Use of a mobile device while an autonomous vehicle is moving is a fireable offense, and “this is emphasized on an ongoing basis,” the statement said.

After the crash, the ride-hailing company said it did a top-to-bottom safety evaluation, reviewing internal processes and safety culture. Uber also said it brought in former transportation safety board chairman Christopher Hart to advise the company on safety.

Both Vasquez and Uber could still face civil liability in the case, Uber for potentially negligent hiring, training and supervision, said Bryant Walker Smith, a University of South Carolina law professor who closely follows autonomous vehicles.

Vasquez could be charged criminally, and if there’s evidence that Uber or its employees acted recklessly, then charges against them are possible, Smith said. But charges against the company are not likely, he added.

“This should not have happened in so many ways and on so many levels,” Smith said. “This report, if true, makes things worse. And obviously it would not look good to a jury.”

Uber settled quickly with some of Herzberg’s family members but others have retained legal counsel.

The Yavapai County Attorney’s Office hasn’t set a deadline for deciding whether to bring charges, said Penny Cramer, assistant to County Attorney Sheila Polk. The prosecutorial agency declined to comment on the police report.

The case was handed to Polk’s office after the prosecutor’s office in metro Phoenix passed on the case, citing a potential conflict of interest. The agency in Phoenix had previously participated in a public-safety campaign with Uber.

On a body camera video the night of the crash, police gathered at the scene quickly realized that they were dealing with a big story because an autonomous vehicle was involved.

An officer who identifies himself as supervisor of the unit that investigates fatal crashes is seen asking a man who appears to be an Uber supervisor about getting video from the SUV and whether Uber’s lawyers have been contacted.

“You guys know as well as I know that this is going to be an international story,” the police supervisor says. “We want to make sure that we’re doing not only what we normally do and not doing anything different, but also making sure that everything’s above board and everything’s out in the open.”

The supervisor goes on to say that he’s going to communicate as honestly as he can. “I hope that you guys do the same because we’re going to be working together throughout this whole process from now, probably for months from now.”

No Drugs, No Alcohol in US Celebrity Chef Bourdain’s Body When He Died: Prosecutor

U.S. celebrity chef Anthony Bourdain, who killed himself in a French hotel room earlier this month, had no narcotics or alcohol in his body when he died, a local prosecutor said on Friday.

Bourdain, host of CNN’s food-and-travel-focused “Parts Unknown” television series, was 61. Brash and opinionated, he had spoken openly about his use of drugs and addiction to heroin earlier in his life.

“No trace of narcotics, no trace of any toxic products, no trace of medicines, no trace of alcohol,” prosecutor Christian de Rocquigny told Reuters.

Bourdain, whose career catapulted him from washing dishes at New York restaurants to dining in Vietnam with President Barack Obama, hanged himself in a hotel room near Strasbourg, France, where he had been working on an upcoming episode of his TV series, according to CNN.

1 More American Confirmed Hurt by Mystery ‘Attack’ in Cuba

One more U.S. Embassy employee in Havana, Cuba, has been affected by mysterious health incidents, the State Department said. 

State Department spokeswoman Heather Nauert said one of two Americans recently evacuated from Cuba was “medically confirmed” to have been affected, while the other was “still being evaluated” by doctors. 

25 Americans affected

In all, 25 Americans have been affected by the mystery ailment in Cuba. 

“We still don’t know, to this day, what is causing it and who is responsible,” Nauert said, noting that investigations were underway in Havana as well as Guangzhou, China, where one employee experienced similar symptoms recently.

The United States has said that the Cuba incidents started in late 2016. The State Department calls them “specific attacks” but has not said what caused them or who was behind them. Cuba has adamantly denied involvement or knowledge. 

Initial speculation centered on some type of sonic attack owing to strange sounds heard by those affected, but an interim FBI report in January found no evidence that sound waves could have caused the damage, The Associated Press has reported.

Warning issued in China

The State Department issued a health warning after the employee in China reported experiencing “subtle and vague, but abnormal, sensations of sound and pressure” and was diagnosed with a mild traumatic brain injury.

Secretary of State Mike Pompeo described it as a “serious medical incident.” 

The new confirmation came less than a week after the U.S. renewed demands on Cuba to determine the source of the “attacks” on U.S. diplomats. Cuba responded by again denying any involvement in or knowledge of any such attacks.

Overweight? Depressed? It May Be Your Microbes

Microbes may be helping stir up anxiety and depression in obese people, if results from a new mouse study hold true in humans. 

The authors link the effects to how the brain responds to insulin, the hormone that regulates sugar levels in the blood. 

The research raises questions about whether changing gut microbes, or changing diet, could help treat these conditions. 

Mood, microbes and metabolism

Obesity triggers changes in metabolism — for example, making liver, muscle, fat and other tissues less responsive to insulin. Left untreated, these changes can lead to diabetes. 

Obese people also have higher rates of anxiety and depression. 

“One could say, ‘Maybe that’s just because they’re obese,’ ” said Harvard Medical School diabetes researcher Ronald Kahn, “but others could say, ‘Maybe there’s a metabolic link.’ ”

“And we asked the question, ‘Maybe the metabolic link is at least partly fueled by the microbiome,’ ” the community of microbes living in a person’s gut, he added.

Those microbes change with diet, and Kahn said different microbes might respond differently to the foods we eat.

To test the theory, Kahn and colleagues fed mice a high-fat diet and studied their behavior as the animals became obese. 

They used common tests to gauge anxious and depressed behavior in rodents — for example, how much time the animals spent hiding in a dark box versus exploring a brightly lit area. The more anxious the mouse, the less time it will spend in the light.

Obese mice spent about 25 percent less time in the light than animals on a normal diet, and they scored higher on the other anxiety and depression tests, too.

Return to normal

But those differences disappeared when obese mice were given antibiotics, even though their weight didn’t change much.

“That really says there’s probably something about the microbiome,” Kahn said. 

The researchers then tested how the animals’ microbiomes affected mice raised in a sterile environment with no microbes of their own. 

Bacteria from obese rodents made these germ-free mice more anxious than microbes from normal mice.

But when germ-free mice got microbes from obese animals that had been given antibiotics, they behaved like normal mice. 

To see what parts of the brain might be responsible for the effects, the researchers focused on two regions involved in metabolism and responses to rewards. They found these regions were less responsive to insulin in the obese mice compared with normal-weight animals. 

Again, antibiotics returned those responses to normal. 

The research appears in the journal Molecular Psychiatry. 

“It was actually quite a surprise,” Kahn said. “Even though we had seen some effects on metabolism in the rest of the body, I was very surprised how dramatic and how clear the effects were also on the brain and on behavior.”

Into the unknown

That doesn’t mean antibiotics are the cure for depression, Kahn warned. The drugs kill good and bad microbes indiscriminately, and taking the medication unnecessarily can contribute to the rising threat of antibiotic resistance. 

Also, what happens in mice does not necessarily happen in humans, he added, or it may happen for only some people. So far, there is not much evidence that probiotics help anxious people. 

“The difficulty is, both of these things — depression and obesity — are complicated things that have multiple, multiple factors influencing them,” said mental health researcher Gregory Simon at Kaiser Permanente Washington Health Research Institute, who was not part of the study.

Microbes are likely just one factor, along with environment, genetics, social influences and more, Simon added.

But Kahn said his group’s research raised interesting questions about how food affects our behavior. 

“I think now we can get some idea that there are a lot of things that are being metabolized by gut bacteria that could affect brain function,” he said.

And he said there might be ways to change brain function by changing those bacteria, by eating helpful microbes or by eating foods that sustain them. 

He and his colleagues are working to figure out exactly which of the hundreds of species of gut bacteria are responsible. At the moment, it’s a mystery.

Turkey Joins Nations Placing New Tariffs on US Products

Turkey announced Thursday that it would impose tariffs on $1.8 billion worth of U.S. goods in retaliation for U.S. President Donald Trump’s tariffs on steel and aluminum imports.

The World Trade Organization said the new Turkish tariffs would amount to $266.5 million on products including cars, coal, paper, rice and tobacco.

Economy Minister Nihat Zeybekci said in a statement that Turkey would not allow itself “to be wrongly blamed for America’s economic challenges.”

He continued, “We are part of the solution, not the problem.”

On Wednesday, the EU announced that it had compiled a list of U.S. products on which it would begin charging import duties of 25 percent, a move that could escalate into a full-blown trade war, especially if U.S. President Donald Trump follows through with his threat to impose tariffs on European cars.

“We did not want to be in this position. However, the unilateral and unjustified decision of the U.S. to impose steel and aluminum tariffs on the EU means that we are left with no other choice,” EU Trade Commissioner Cecilia Malmstrom said in a statement.

The commission, which manages the daily business of the EU, adopted a law that places duties on $3.2 billion worth of U.S. goods, including aluminum and steel products, agricultural products, bourbon and motorcycles.

Malmstrom said that the EU response was consistent with World Trade Organization rules and that the tariffs would be lifted if the U.S. rescinded its metal tariffs, which amount to $7.41 billion.

Trump slapped tariffs of 25 percent on steel and 10 percent on aluminum on the EU, Canada and Mexico, which went into effect at the beginning of June.

Canada said it would impose retaliatory tariffs on $12.5 billion worth of U.S. products on July 1.

Mexico imposed tariffs two weeks ago on a range of U.S. products, including steel, pork and bourbon.

Study: Leptospirosis Spread by Cattle, Not Just Rats

Fever, chills, and muscle pain aren’t the symptoms just of malaria. They could be signs of leptospirosis, which infects millions of people each year — primarily in tropical regions. 

The under-reported disease is usually spread though contact with rodents, but a new study finds this trend may not hold in northern Tanzania or beyond.

Research in Asia has tied living in close quarters with rats to outbreaks of leptospirosis. The bacterial infection causes symptoms that are often mistaken for malaria. Severe cases can be life-threatening, says Professor Albert Ko at the Yale School of Public Health.

“Our group has done global burden of disease studies on this and there are over a million a cases a year and roughly 60 thousand deaths,” said Ko.

Common source of fevers

Leptospirosis is becoming recognized as a common source of fevers in Africa. But the source of the disease was unclear. It could be rats, or it could be something else, said Michael Maze, of the University of Otago.

“Well, we know that leptospirosis has many possible animal hosts,” said Maze. “I guess the story starts when we identified how common leptospirosis was the cause of severe fever in people coming to the hospital in northern Tanzania.”

Maze and an international team of researchers asked those patients about their lifestyles: how many rats they saw around their home… whether they owned livestock and if so, what kind?

They also tested blood samples for leptospirosis infections. Of the nearly 900 people tested, almost a third were infected, or had been. 

The researchers also trapped almost 400 rats in nearby villages. They tested the rodents to see if they carried the leptospira bacterium like their Asian cousins. They did not.

But cattle did — they found over seven percent of them carried up to four types of leptospira that could potentially infect humans. Goats and sheep did, too, though less often.

Blood samples match

This result matched the findings from the patients’ blood samples. People who owned livestock were most likely to have leptospirosis infections, especially cattle owners.

“Leptospirosis is carried in the renal tract — so the kidney and the bladder — and comes out in the urine of infected animals,” said Maze. “So even simple things like avoiding urine while doing activities such as, for example, milking cattle would be a good first step.”

Maze recommends abattoir workers and dairy farmers wear gloves and other protective clothing.

“A cow is much bigger and it produces a much larger volume of urine and so that creates a greater opportunity for exposure,” said Maze.

But Maze and colleagues found doctors did not diagnose a single one of the patients in the study with leptospirosis. In fact, one in four active cases was misdiagnosed as malaria — even though the patients’ blood tested negative for parasites.

Symptoms similar

Maze says one reason is because symptoms of the two diseases are similar and there is not an accurate, simple test for leptospirosis that can be run in regional hospitals.

“The second reason is that clinician awareness of these diseases is low,” said Maze. “If you don’t recognize them it becomes a cycle where they’re never diagnosed so you never recognize them.”

Yale’s Albert Ko says the work Maze and his colleagues have done provides a better understanding of how leptospirosis spreads.

“This is an important study specifically because it provides key information on risk factors in a high burden setting, said Ko. “In specifically among this at-risk population of vulnerable pastoralist society.”

Intel CEO Resigns After Probe Into Relationship With Employee

Intel Corp Chief Executive Brian Krzanich resigned on Thursday after a probe found his consensual relationship with an employee violated company policy.

The head of the largest U.S. chipmaker is the latest in a line of powerful men in business and politics to lose their jobs or resign over relationships viewed as inappropriate, a phenomenon highlighted by the #MeToo movement.

“An ongoing investigation by internal and external counsel has confirmed a violation of Intel’s non-fraternization policy, which applies to all managers,” Intel said in a statement.

The board named Chief Financial Officer Robert Swan as interim CEO and said it has begun a search for a permanent CEO, including both internal and external candidates.

Intel declined to give any further information about the probe. Intel shares fell 1.5 percent in early trade.

Wall Street took Krzanich’s unexpected departure in stride.

“Although we respect Krzanich’s efforts in redirecting Intel’s strategy from a computer-centric to a data-centric company, we view Intel as a process-driven company with a deep bench of CEO candidates that can continue to drive the corporate strategy,” said Kevin Cassidy, an analyst at Stifel.

Krzanich, 58, was appointed Intel CEO in May 2013, and was in charge of moving the company’s focus to growing data centers from personal computers. Intel shares more than doubled during his tenure.

He was recently credited with containing the fallout from the disclosure of some security flaws in the company’s chips that could allow hackers to steal data from computers, although his sale of some Intel stock before the flaws were disclosed to investors attracted some criticism.

“There are no new payments as part of his departure,” a source familiar with the company told Reuters.

Temporary replacement Swan has been Intel’s CFO since October 2016 and previously spent nine years as CFO of eBay Inc.

Intel on Thursday raised its second-quarter revenue and profit forecast, saying it expects quarterly revenue of about $16.9 billion and adjusted profit of about 99 cents per share, up from a previous forecast of $16.3 billion in revenue and adjusted earnings per share of 85 cents.

Analysts on average were expecting revenue of $16.29 billion and adjusted profit of 85 cents per share.

Scientists: Nations Must Slow Plastic Buildup Caused by China’s Ban

China’s decision to stop accepting plastic waste from other countries is causing plastic to pile up around the globe, and wealthy countries must find a way to slow the accumulation of one of the most ubiquitous materials on the planet, a group of scientists said.

The scientists sought to quantify the impact of the Chinese import ban on the worldwide trade in plastic waste, and found that other nations might need to find a home for more than 122 million tons (110 million metric tons) of plastic by 2030. The ban went into effect Dec. 31, 2017, and the stockpiling trend figures to worsen, the scientists said.

Wealthy countries such as the United States, Japan and Germany have long sent their plastic recyclables to China, and the country doesn’t want to be the world’s dumping ground for plastic anymore. The study found China has taken more than 116 million tons (105 million metric tons) of the material since 1992, the equivalent of the weight of more than 300 Empire State Buildings.

The change is forcing countries to rethink how they deal with plastic waste. They need to be more selective about what they choose to recycle, and more fastidious about reusing plastics, said Amy Brooks, first author on the study and a doctoral student in engineering at the University of Georgia. In the meantime, Brooks said, more plastic waste is likely to get incinerated or sent to landfills.

“This is a wake-up call. Historically, we’ve been depending on China to take in this recycled waste and now they are saying no,” she said. “That waste has to be managed, and we have to manage it properly.”

The study was published Wednesday in the journal Science Advances. Using United Nations data, it found that China has dwarfed all other plastics importers, accounting for about 45 percent of the world’s plastic waste since 1992. The ban is part of a larger crackdown on foreign garbage, which is viewed as a threat to health and environment.

Some countries that have seen an increase in plastic waste imports since China’s ban — such as Thailand, Vietnam and Malaysia — are already looking to enforce bans of their own because they are quickly becoming overburdened, Brooks said.

The study illustrates that plastic, which has a wide array of uses and formulations, is more difficult to recycle than other materials, such as glass and aluminum, said Sherri Mason, who was not involved in the study and is the chair of the geology and environmental sciences department at the State University of New York at Fredonia.

Many consumers attempt to recycle plastic products that can’t ultimately be recycled, Mason said. One solution could be to simplify the variety of plastics used to make products, she said.

“We have to confront this material and our use of it, because so much of it is single use disposable plastic and this is a material that doesn’t go away,” Mason said. “It doesn’t return to the planet the way other materials do.”

The plastics import ban has attracted the attention of the U.S. recycling industry. The National Recycling Coalition said in a statement in mid-May that it must “fundamentally shift how we speak to the public” and “how we collect and process” recyclables.

“We need to look at new uses for these materials,” said Marjorie Griek, the coalition’s executive director. “And how do you get manufacturers to design a product that is more easily recyclable.”
