Hundreds of environmental activists marched in the Kenyan capital, Nairobi, Saturday demanding drastic curbs on plastic production, ahead of a meeting to negotiate a global plastics treaty. Representatives of more than 170 nations will meet in Nairobi Monday to negotiate what concrete measures should be included in a binding worldwide treaty to end plastic pollution. Marchers waved placards reading “Plastic crisis = climate crisis” and “End multigenerational toxic exposure.” They chanted “let polluters pay the price” as they walked slowly behind a ceremonial band from central Nairobi to a park in the west of the capital. Nations agreed last year to finalize by 2024 a world-first U.N. treaty to address the scourge of plastics found everywhere from mountain tops to ocean depths and within human blood and breast milk. Negotiators have met twice already but Nairobi is the first opportunity to debate a draft treaty published in September that outlines the many pathways to tackling the plastic problem. The Nov. 13-19 meeting is the third of five sessions in a fast-tracked process aiming to conclude negotiations next year so the treaty can be adopted by mid-2025. At the last talks in Paris, campaigners accused large plastic-producing nations of deliberately stalling after two days were lost debating procedural points. This time around, the sessions have been extended by two days but there are still concerns a weaker treaty could emerge if time for detailed discussion is swallowed up going in circles. Global plastic production has more than doubled since the start …
US Childhood Vaccination Exemptions at Highest Level Ever
The proportion of U.S. kindergartners exempted from school vaccination requirements has hit its highest level ever, 3%, U.S. health officials said Thursday. More parents are questioning routine childhood vaccinations that they used to automatically accept, an effect of the political schism that emerged during the pandemic around COVID-19 vaccines, experts say. Even though more kids were given exemptions, the national vaccination rate held steady: 93% of kindergartners got their required shots for the 2022-23 school year, the same as the year before, the Centers for Disease Control and Prevention said in a report Thursday. The rate was 95% in the years before the COVID-19 pandemic. “The bad news is that it’s gone down since the pandemic and still hasn’t rebounded,” said Dr. Sean O’Leary, a University of Colorado pediatric infectious diseases specialist. “The good news is that the vast majority of parents are still vaccinating their kids according to the recommended schedule.” All U.S. states and territories require that children attending child care centers and schools be vaccinated against a number of diseases, including, measles, mumps, polio, tetanus, whooping cough and chickenpox. All states allow exemptions for children with medical conditions that prevents them from receiving certain vaccines. And most also permit exemptions for religious or other nonmedical reasons. In the last decade, the percentage of kindergartners with medical exemptions has held steady, at about 0.2%. But the percentage with nonmedical exemptions has inched up, lifting the overall exemption rate from 1.6% in the 2011-12 school year to 3% last …
Wildlife Refuge Pond in Hawaii Turns Pink; Drought May Be to Blame
A pond in Hawaii has turned so bubble-gum pink it could be from the set of Barbie, but the bizarre phenomenon is no cause for a dance party. Drought may be to blame for the strange hue, scientists say, and they’re warning against entering the water or drinking it. Staff at the Kealia Pond National Wildlife Refuge on Maui have been monitoring the pink water since Oct. 30. “I just got a report from somebody that was walking on the beach, and they called me up like, ‘There’s something weird going on over here,’” said Bret Wolfe, the refuge manager. Wolfe was concerned the bright pink could be a sign of an algae bloom, but lab tests found toxic algae was not causing the color. Instead an organism called halobacteria might be the culprit. Halobacteria are a type of archaea or single-celled organism that thrive in bodies of water with high levels of salt. The salinity inside the Kealia Pond outlet area is currently greater than 70 parts per thousand, which is twice the salinity of seawater. Wolfe said the lab will need to conduct a DNA analysis to definitively identify the organism. Maui’s drought is likely contributing to the situation. Normally Waikapu Stream feeds into Kealia Pond and raises water levels there, but Wolfe said that hasn’t happened in a long time. When it rains, the stream will flow into Kealia’s main pond and then into the outlet area that’s now pink. This will reduce the salinity and potentially …
Tuberculosis Remains One of World’s Deadliest Diseases, but Vaccine Hopes Rise

Quakes Rock Southwestern Iceland as Volcanic Eruption Looms
Iceland declared a state of emergency on Friday after a series of powerful earthquakes rocked the country’s southwestern Reykjanes peninsula in what could be a precursor to a volcanic eruption. “The National police chief … declares a state of emergency for civil defense due to the intense earthquake (activity) at Sundhnjukagigar, north of Grindavik,” the Department of Civil Protection and Emergency Management said in a statement. “Earthquakes can become larger than those that have occurred, and this series of events could lead to an eruption,” the administration warned. The Icelandic Met Office (IMO) said an eruption could take place “in several days.” The village of Grindavik, home to around 4,000 people, is located some three kilometers (1.86 miles) southwest of the area where Friday’s earthquake swarm was registered. It has evacuation plans in place in case of an eruption. Thousands of tremors since October Around 1730 GMT, two strong earthquakes were felt as far away as the capital Reykjavik some 40 kilometers away, and along much of the country’s southern coast, rattling windows and household objects. According to preliminary IMO figures, the biggest tremor had a magnitude of 5.2, north of Grindavik. Police closed a road running north-south to Grindavik on Friday after it was damaged by the tremors. Some 24,000 tremors have been registered on the peninsula since late October, according to the IMO, with “a dense swarm” of nearly 800 quakes registered between midnight and 1400 GMT Friday. The IMO noted an accumulation of magma underground at a …
Tuberculosis Remains One of World’s Deadliest Diseases, But Hope for Vaccine Rises
Global cases of tuberculosis — also known as TB — continued to rise last year as disruption to health services caused by the COVID-19 pandemic set back efforts to fight the disease, according to the latest report from the World Health Organization. Tuberculosis, an infectious disease that usually attacks the lungs, is both preventable and curable. It caused an estimated 1.3 million deaths in 2022 — a 19% drop from the year before, said the annual WHO report published last week. However, there was a small increase in the number of global TB cases to an estimated 10.6 million. Some 40% of people living with TB are undiagnosed and untreated. The disease is just behind COVID-19 as the world’s deadliest infectious illness, with India, Indonesia and the Philippines particularly affected. COVID disruption The COVID-19 pandemic, which began in 2020, saw health services overwhelmed in many parts of the world. TB diagnosis and treatment levels plummeted, said Dr. Lucica Ditiu, the executive director of the Geneva-based Stop TB Partnership. “Unfortunately, the incidence of TB is growing. We used to have a decline of 2% per year. And then due to COVID, we have now an increase for the last two years — 2021 and 2022 — of almost 4%,” she told VOA. The World Health Organization estimates COVID-related disruptions resulted in almost half a million excess deaths from TB in the three years from 2020 to 2022. Childhood TB The report also reveals a concerning lack of progress in some areas, …
US Hit by 25 Reported Billion-Dollar Climate Disasters in 2023
The U.S. National Oceanic and Atmospheric administration — NOAA — reports the U.S. has seen 25 separate weather or climate “disasters” — events causing damage or losses exceeding $1 billion — so far this year, the highest number since the agency began tracking such events 43 years ago. In a report issued this week, NOAA said severe thunderstorms moving through Oklahoma and other southern Plains states September 23 and 24 brought high winds and large hail, causing enough damage to rank as the 25th weather disaster so far in 2023. The agency said disasters through October of this year included 19 severe storms, two flooding events, a winter storm in the northeastern U.S., a drought and heat wave in the central and southern states, one wildfire (on Maui in August), and one tropical cyclone (Hurricane Idalia in Florida). NOAA said these events took the lives of 464 people and had a severe economic impact on the regions where they occurred. The total cost in damages from these events was more than $73 billion. The year-to-date tally exceeds 2020, which saw 19 disasters through October. NOAA reports the annual average number of such disaster events between 1980 and 2022 was 8.1 per year. The agency reports the annual average jumped in the most recent five years (2018-2022) to 18 disasters per year. Since 1980, the U.S. has sustained 373 separate weather and climate events resulting in overall damages or costs reaching or exceeding $1 billion, according to NOAA. The …
What Do We Expect From COP28?
Debates over the phasing out of fossil fuels and a new climate damage fund for the Global South are expected to take center stage in the climate negotiations at the U.N. Climate Change Conference, or COP28, in Dubai, UAE, later this month, experts say. This follows the release of the first Global Stocktake report in September. The “stocktake,” to be conducted every five years, is designed to evaluate the world’s progress toward meeting the goals of the 2015 Paris Agreement and recommend steps to address shortfalls. The report shows alarming results: Countries are far from reaching the Paris Agreement goals, and the window within which the world can still limit global temperature increase to 1.5 degrees Celcius above pre-industrial levels is “rapidly narrowing.” To reach that goal, nations would have to slash global greenhouse gas emissions by 43% by 2030 and 60% by 2035 compared with 2019 levels. This year is set to be the hottest on record, with historic heatwaves hitting the United States, China and southern Europe this summer. Leading climate scientists attribute their intensity almost entirely to the burning of fossil fuels. The World Meteorological Organization called in July for governments to adopt heat action plans to “protect hundreds of thousands of people dying from preventable heat-related causes each year.” Climate change “is an existential threat,” said Niklas Hohne, founder of the climate NGO NewClimate Institute and a former member of the secretariat of the U.N. Framework Convention on Climate Change. “But the warming alone doesn’t make …

Kenyan University Student Innovators Manufacture Flour Using Grass
Students from Kabarak University in Kenya’s Rift Valley have developed a method for turning grass into flour and then fortifying it for human consumption.

Kerry: US and China Have ‘Some Agreement’ on Climate Issues
U.S. climate envoy John Kerry said talks this week with his Chinese counterpart resulted in “some agreement” on climate issues that leave him optimistic about the U.N. climate summit scheduled for later this month in Dubai. Speaking at the Bloomberg New Economy Forum in Singapore, Kerry said Friday that he met for four days this week with Chinese climate envoy Xie Zhenhua in California. He described their talks as “productive” and, without providing details, said they had reached “some agreement on reducing emissions and the direction we have to go.” Kerry said, “I am hopeful about that,” adding that details of the agreements would be released soon. The U.N. Climate Change Conference, known as COP28, is scheduled for the end of this month. The climate conference seeks to meet and expand on climate goals established during the Paris agreement of 2015, in which some 200 nations agreed to limit the rise of global temperatures to 1.5 degrees Celsius, or about pre-industrial age levels. Kerry said the goal, as in the previous climate conferences, “is to open up the opportunity to keep 1.5 degrees alive.” Any agreements between the United States and China — the world’s two largest polluters — would be integral to the success of the conference. The U.S. climate envoy said the use of fossil fuels — coal in particular — is likely to be a central part of the discussion at the conference. China is the world’s largest user of fossil fuels and relies on coal for …
Indian Capital Gets Breather as Rain Brings Respite from Smog
Rain in New Delhi and its suburbs brought relief Friday morning to the Indian capital, where authorities were mulling seeding clouds to improve the toxic air gripping the city. New Delhi, which was the most polluted in the world until Thursday, saw its air quality index (AQI) improve to 127 early Friday – a welcome change from the “hazardous” 400-500 level seen during the past week, according to the Swiss group IQAir. India’s weather department has forecast intermittent rain over the city and adjoining areas until early noon on Friday. Light showers are also expected in neighboring states like Punjab, Haryana, and Rajasthan. On Friday morning, New Delhi was the 10th most polluted city in the world, while Kolkata, in India’s east, topped the global chart with an AQI of 303. Meanwhile, air in the financial capital of Mumbai has markedly improved due to showers in nearby coastal areas. This year, attention on the worsening air quality has cast a shadow over the cricket World Cup hosted by India. Scientists and authorities were planning to seed clouds in New Delhi around Nov. 20 to trigger heavy rain, the first such attempt to clean the air. A thick layer of smog envelops the city every year ahead of winter as heavy, cold air traps dust, vehicle emissions and smoke from burning crop stubble in Punjab and Haryana. Friday’s rain comes two days before the Diwali festival, when many people defy a ban on firecrackers, causing a spike in air pollution. The …
Man Receives First Eye Transplant in Step Toward One Day Restoring Sight
Surgeons have performed the world’s first transplant of an entire human eye, an extraordinary addition to a face transplant — although it’s far too soon to know if the man will ever see through his new left eye. An accident with high-voltage power lines destroyed most of Aaron James’ face and one eye. His right eye still works. But surgeons at NYU Langone Health hoped replacing the missing one would yield better cosmetic results for his new face, because it would support the transplanted eye socket and lid. The NYU team announced Thursday that so far, it’s doing just that. James is recovering well from the dual transplant last May, and the donated eye looks remarkably healthy. “It feels good. I still don’t have any movement in it yet. My eyelid, I can’t blink yet. But I’m getting sensation now,” James told The Associated Press as doctors examined his progress recently. “You got to start somewhere, there’s got to be a first person somewhere,” said James, 46, of Hot Springs, Arkansas. “Maybe you’ll learn something from it that will help the next person.” Today, transplants of the cornea — the clear tissue in front of the eye — are common to treat certain types of vision loss. But transplanting the whole eye — the eyeball, its blood supply and the critical optic nerve that must connect it to the brain — is considered a moonshot in the quest to cure blindness. Whatever happens next, James’ surgery offers scientists an unprecedented …
Recent Floods in Kenya Kill 15, Displace Thousands
Recent heavy rain and flooding killed 15 people in Kenya and displaced thousands of others, the Kenya Red Cross Society says. The heavy rainfall also killed livestock and destroyed businesses and farmland, said Peter Murgor, a disaster risk reduction and climate change adaptation manager with the Kenya Red Cross Society. “Schools [are] being affected … and even hospital facilities in some of the places that have been marooned are also affected,” Murgor told VOA. The situation could get worse, Murgor said. In its forecast for this year’s last quarter, the Kenya Meteorological Department had warned the country will experience above-average rainfall, driven by warmer sea surface temperatures over the central and eastern equatorial Pacific Ocean. “We are informed by the [weather forecaster] that November normally is the peak,” Murgor told VOA. “If November is the peak and we are just at the beginning of November, chances are … the situation is likely to worsen in the month towards the end, probably seeing a bit more people being displaced, probably seeing a bit more loss of livelihoods.” Nearly half of the 47 counties in Kenya are at risk, he said, with the northeastern part of the country being the most affected. Heavy rains also have affected neighboring Uganda, Ethiopia and Somalia, where the government declared a state of emergency after 29 people died and hundreds of thousands were displaced as a result of the extreme weather. Meanwhile, in Kenya, Murgor said flash floods would likely cause more problems. “We are likely …
‘Like Breathing Poison’: Delhi Children Hardest Hit by Smog
Crying in a hospital bed with a nebulizer mask on his tiny face, 1-month-old Ayansh Tiwari has a thick, hacking cough. His doctors blame the acrid air that blights New Delhi every year. The spartan emergency room of the government-run Chacha Nehru Bal Chikitsalaya hospital in the Indian capital is crowded with children struggling to breathe — many with asthma and pneumonia, which spike as air pollution peaks each winter in the megacity of 30 million people. Delhi regularly ranks among the most polluted major cities on the planet, with a melange of factory and vehicle emissions exacerbated by seasonal agricultural fires. “Wherever you see there is poisonous smog,” said Ayansh’s mother Julie Tiwari, 26, as she rocked the baby on her lap, attempting to calm him. “I try to keep the doors and windows closed as much as possible. But it’s like breathing poison all the time. I feel so helpless,” she told AFP, fighting back tears. On Thursday, the level of PM2.5 particles — the smallest and most harmful, which can enter the bloodstream — topped 390 micrograms per cubic meter, according to monitoring firm IQAir, more than 25 times the daily maximum recommended by the World Health Organization. Government efforts have so far failed to solve the country’s air quality problem, and a study in the Lancet medical journal attributed 1.67 million premature deaths to air pollution in the world’s most populous country in 2019. ‘Maddening rush’ “It’s a maddening rush in our emergency room during this …
Transsexual People Can Be Baptized Catholic, Serve as Godparents, Vatican Says
Transsexual people can be godparents at Roman Catholic baptisms, witnesses at religious weddings and receive baptism themselves, the Vatican’s doctrinal office said on Wednesday, responding to questions from a bishop. The department, known as the Dicastery of the Doctrine of the Faith, was vague, however, in response to a question about whether a same-sex couple could have a church baptism for an adopted child or one obtained through a surrogate mother. Bishop Jose Negri of Santo Amaro, Brazil, sent the doctrinal office six questions in July regarding LGBTQ people and their participation in the sacraments of baptism and matrimony. The three pages of questions and answers were signed by the department’s head, Argentine Cardinal Víctor Manuel Fernandez, and approved by Pope Francis on October 31. They were posted in Italian on the department’s website Wednesday. Francis, 86, has tried to make the church more welcoming to the LGBTQ community without changing church teachings, including one saying that same-sex attraction is not sinful but same-sex acts are. In response to a question of whether transsexual people can be baptized, the doctrinal office said they could with some conditions and as long as there is “no risk of causing a public scandal or disorientation among the faithful.” It said a transsexual people could be godparents at a baptism at the discretion of the local priest, as well as a witness at a church wedding, but the local priest should exercise “pastoral prudence” in his decision. A person in a same-sex relationship could …
Workers Exposed to Sunlight at High Risk of Deadly Skin Cancer
A new study by the World Health Organization and International Labour Organization finds nearly 1 in 3 deaths from non-melanoma skin cancer are caused by working in the sun. “We know that around the world, 1.6 billion workers are exposed to solar ultraviolet radiation globally. Depending on where you live, you will have more or less protection,” said Maria Neira, director of the WHO department of environment, climate change and health. “The number of those deaths from occupational non-melanoma skin cancer burden has doubled over the last 20 years and, of course, unfortunately, we can expect to see many cases in the future. It takes a number of years to develop a cancer,” she said. The joint study issued Wednesday provides data for 183 countries and produces the first comprehensive global picture of the extent of this growing occupational health problem. Authors of the study say governments can use their data to identify unsafe workplaces and design policies to protect workers from the harmful effects of the sun’s rays. According to the joint estimates, 1 in 4 of the 1.6 billion people of working age was exposed to UV radiation while working outdoors in 2019 and nearly 19,000 died from non-melanoma skin cancer. “We pooled a large number of case control studies, epidemiological evidence in three regions of the world, 90,000 people, and found there was a 60% increased risk” of developing non-melanoma skin cancer among working people exposed to solar UV radiation, said Frank Pega, a technical officer in …
FDA Approves New Version of Diabetes Drug for Weight Loss
A new version of the popular diabetes treatment Mounjaro can be sold as a weight-loss drug, U.S. regulators announced Wednesday. The U.S. Food and Drug Administration approved Eli Lilly’s Zepbound, or tirzepatide. The drug helped dieters lose about a quarter of their body weight, or 27 kilograms, in a recent study. Zepbound is the latest diabetes drug approved for weight loss, joining Novo Nordisk’s Wegovy, a high-dose version of its diabetes treatment Ozempic. The FDA approved Lilly’s drug for people who are considered obese, with a body mass index of 30 or higher, or those who are overweight with a related health condition, like high blood pressure, high cholesterol or diabetes. The drug should be paired with a healthy diet and regular exercise, the FDA said. In the U.S., at least 100 million adults and about 15 million children are considered obese. The drug tirzepatide in Zepbound and Mounjaro and semaglutide in Wegovy and Ozempic work by mimicking hormones that kick in after people eat to regulate appetite and the feeling of fullness. Both imitate a hormone called glucagon-like peptide-1, known as GLP-1. Tirzepatide targets a second hormone, called glucose-dependent insulinotropic polypeptide, or GIP. Zepbound appears to spur greater weight loss than Wegovy. Approved for chronic weight management in 2021, Wegovy helped people lose about 15% of their body weight or 15.4 kilograms, according to study results. “This would be the most highly efficacious drug ever approved for the treatment of obesity,” said Dr. Fatima Cody Stanford, an obesity medicine …
UN: Excess Global Fossil Fuel Production will Undermine Goal of Limiting Global Temperatures
A new United Nations report says the amount of fossil fuels produced in 2030 will far exceed the levels needed for the world to alleviate global warming. The study by the U.N. Environment Program says 20 of the world’s major fossil fuel producing nations are on track to produce about 110% more oil, gas and coal in 2030 than the amounts consistent with limiting global temperature rise to 1.5 degrees celsius. Holding down global temperatures to a 1.5 degree increase compared with pre-industrial levels was a key goal of the global climate pact signed in Paris in 2015. The 20 countries in the report include Australia, Brazil, Russia, Saudi Arabia, the United Arab Emirates and the United States, which account for 82% of fossil fuel production and 73% of consumption. The report says none of them have committed to reducing production of oil, gas and coal to levels that would meet the 1.5 degree Celsius threshold. Many of those countries have continued to offer government subsidies or tax breaks to fossil fuel companies, while others produce oil through state-owned enterprises. The report was also produced by experts with the Stockholm Environment Institute, the International Institute for Sustainable Development, and research groups Climate Analytics and E3G. Some information for this report came from The Associated Press, Reuters, Agence France-Presse. …
This Year ‘Virtually Certain’ to be Warmest in 125,000 Years, EU Scientists Say
This year is “virtually certain” to be the warmest in 125,000 years, European Union scientists said on Wednesday, after data showed last month was the world’s hottest October in that period. Last month smashed through the previous October temperature record, from 2019, by a massive margin, the EU’s Copernicus Climate Change Service (C3S) said. “The record was broken by 0.4 degrees Celsius, which is a huge margin,” said C3S Deputy Director Samantha Burgess, who described the October temperature anomaly as “very extreme.” The heat is a result of continued greenhouse gas emissions from human activity, combined with the emergence this year of the El Nino weather pattern, which warms the surface waters in the eastern Pacific Ocean. Globally, the average surface air temperature in October was 1.7 degrees Celsius warmer than the same month in 1850-1900, which Copernicus defines as the pre-industrial period. The record-breaking October means 2023 is now “virtually certain” to be the warmest year recorded, C3S said in a statement. The previous record was 2016, another El Nino year. Copernicus’ dataset goes back to 1940. “When we combine our data with the IPCC, then we can say that this is the warmest year for the last 125,000 years,” Burgess said. The longer-term data from the U.N. climate science panel IPCC includes readings from sources such as ice cores, tree rings and coral deposits. The only other time before October a month breached the temperature record by such a large margin was in September 2023. “September really, really …

Syphilis Cases in US Newborns Skyrocketed in 2022
Alarmed by yet another jump in syphilis cases in newborns, U.S. health officials are calling for stepped-up prevention measures, including encouraging millions of women of childbearing age and their partners to get tested for the sexually transmitted disease. More than 3,700 babies were born with congenital syphilis in 2022 — 10 times more than a decade before and a 32% increase from 2021, the Centers for Disease Control and Prevention said Tuesday. Syphilis caused 282 stillbirth and infant deaths, nearly 16 times more than the 2012 deaths. The 2022 count was the most in more than 30 years, CDC officials said, and in more than half of the congenital syphilis cases, the mothers tested positive during pregnancy but did not get properly treated. The rise in congenital syphilis comes despite repeated warnings by public health agencies, and it’s tied to the surge in primary and secondary cases of syphilis in adults, CDC officials said. It’s also been increasingly difficult for medical providers to get benzathine penicillin injections — the main medical weapon against congenital syphilis — because of supply shortages. “It is clear that something is not working here, that something has to change,” the CDC’s Dr. Laura Bachmann said. “That’s why we’re calling for exceptional measures to address this heartbreaking epidemic.” The federal agency wants medical providers to start syphilis treatment when a pregnant woman first tests positive, rather than waiting for confirmatory testing, and to expand access to transportation so the women can get treatment. The CDC also …
Star-filled Euclid Images Spur Mission to Probe ‘Dark Universe’
European astronomers on Tuesday released the first images from the newly launched Euclid space telescope, designed to unlock the secrets of dark matter and dark energy — hidden forces thought to make up 95% of the universe. The European Space Agency, which leads the six-year mission with NASA as a partner, said the images were the sharpest of their kind, showcasing the telescope’s ability to monitor billions of galaxies up to 10 billion light years away. The images spanned four areas of the relatively nearby universe, including 1,000 galaxies belonging to the massive Perseus cluster just 240 million light years away, and more than 100,000 galaxies spread out in the background, ESA said. Scientists believe vast, seemingly organized structures such as Perseus could have formed only if dark matter exists. “We think we understand only 5% of the universe. That’s the matter that we can see,” ESA’s science director Carole Mundell told Reuters. “The rest of the universe we call dark because it doesn’t produce light in the normal electromagnetic spectrum,” she said. “But we know its effect because we see the effect on visible matter.” Tell-tale signs of the hidden force exerted by dark matter include galaxies rotating more quickly than scientists would expect from the amount of visible matter that can be detected. Its influence is also implicated in pulling together some of the most massive structures in the universe, such as clusters of galaxies, Mundell said. Dark energy is even more enigmatic. Its hypothetical existence was established …
Why Sweden Going Smoke-Free May Not be Such Good ‘Snus’
Sweden is poised to become Europe’s first smoke-free country largely thanks to the popularity of snus, a kind of moist snuff which is placed under the upper lip. But some are worried the tobacco industry is peddling a “fairytale” that is too good to be true. Used by one in seven Swedes, snus has, according to the government, helped slash the number of smokers from 15% of the population in 2005 to 5.2% last year, a record low in Europe. A country is considered smoke-free when less than 5% of its population are daily smokers. Snus has been banned in the European Union since 1992. But Sweden negotiated an exemption when it joined the bloc three years later. At the Swedish Match factory in the western city of Gothenburg, thousands of doses of snus wend their way through a complex web of machinery producing the sachets. The company sold 277 million boxes of snus in Sweden and Norway in 2021. “We have used it for 200 years in Sweden. [It’s] part of the Swedish culture, just like many other European countries have their wine culture,” Swedish Match spokesman Patrik Hildingsson told AFP. Clad in a white lab coat, he described the manufacturing process. “Tobacco comes from India or the United States. It goes through this silo and is then packed inside the pouches like tea bags and then into these boxes.” There are two types: traditional brown snus, which contains tobacco, and white snus, which is …
