BUSAN, SOUTH KOREA — The world’s nations will wrap up negotiating a treaty this weekend to address the global plastic pollution crisis.

Their meeting is scheduled to conclude Sunday or early Monday in Busan, South Korea, where many environmental organizations have flocked to push for a treaty to address the volume of production and toxic chemicals used in plastic products.

Greenpeace said it escalated its pressure Saturday by sending four international activists to Daesan, South Korea, who boarded a tanker headed into port to load chemicals used to make plastics.

Graham Forbes, who leads the Greenpeace delegation in Busan, said the action is meant to remind world leaders they have a clear choice: Deliver a treaty that protects people and the planet, or side with industry and sacrifice the health of every living person and future generations.

Here’s what to know about plastics:

Every year, the world produces more than 400 million tons of new plastic.

The use of plastics has quadrupled over the past 30 years. Plastic is ubiquitous. And every day, the equivalent of 2,000 garbage trucks full of plastic are dumped into the world’s oceans, rivers and lakes, the U.N. said. Most nations agreed to make the first global, legally binding plastic pollution accord, including in the oceans, by the end of 2024.

Plastic production could climb about 70% by 2040 without policy changes.

The production and use of plastics globally is set to reach 736 million tons by 2040, according to the intergovernmental Organization for Economic Co-operation and Development.

Panama is leading an effort to address the exponential growth of plastic production as part of the treaty, supported by more than 100 countries. There’s just too much plastic, said Juan Carlos Monterrey, head of Panama’s delegation.

“If we don’t have production in this treaty, it is not only going to be horribly sad, but the treaty may as well be called the greenwashing recycling treaty, not the plastics treaty,” he said in an interview. “Because the problem is not going to be fixed.”

China, the United States and Germany are the biggest plastics players.

China was by far the biggest exporter of plastic products in 2023, followed by Germany and the U.S., according to the Plastics Industry Association.

Together, the three nations account for 33% of the total global plastics trade, the association said.

The United States supports having an article in the treaty that addresses supply, or plastic production, a senior member of the U.S. delegation told The Associated Press Saturday.

Most plastic ends up as waste

Less than 10% of plastics are recycled. Most of the world’s plastic goes to landfills, pollutes the environment or is burned.

Sarah Dunlop, head of plastics and human health at the Minderoo Foundation, said chemicals are leaching out of plastics and “making us sick.”

The International Indigenous Peoples Forum on Plastics held an event about the impact of plastics Saturday on the sidelines of the talks. They want the treaty to fully recognize their rights and the universal human right to a healthy, clean, safe and sustainable environment.

Juan Mancias of the Carrizo/Comecrudo Nation in Texas spoke about feeling a spiritual connection to the land.

“Five hundred years ago, we had clean water, clean air, and there was no plastics,” he said. “What happened?”

Many plastics are used for packaging

About 40% of all plastics are used in packaging, according to the United Nations. This includes single-use plastic food and beverage containers — water bottles, takeout containers, coffee lids, straws and shopping bags — that often end up polluting the environment.

U.N. Environment Program Executive Director Inger Andersen told negotiators in Busan the treaty must tackle this problem.

“Are there specific plastic items that we can live without, those that so often leak into the environment? Are there alternatives to these items? This is an issue we must agree on,” she said.

YANQING, CHINA — In a research facility in the northwest of Beijing, molecular biologist Li Jieping and his team harvest a cluster of seven unusually small potatoes, one as tiny as a quail’s egg, from a potted plant.

Grown under conditions that simulate predictions of higher temperatures at the end of the century, the potatoes provide an ominous sign of future food security.

At just 136 grams, the tubers weigh less than half that of a typical potato in China, where the most popular varieties are often twice the size of a baseball.

China is the world’s biggest producer of potatoes, which are crucial to global food security because of their high yield relative to other staple crops.

But they are particularly vulnerable to heat, and climate change, driven by fossil fuel emissions, is pushing temperatures to dangerous new heights while also worsening drought and flooding.

With an urgent need to protect food supplies, Li, a researcher at the International Potato Center (CIP) in Beijing, is leading a three-year study into the effects of higher temperatures on the vegetable. His team is focusing on China’s two most common varieties.

“I worry about what will happen in the future,” Li said. “Farmers will harvest fewer potato tubers, it will influence food security.”

Li’s team grew their crop over three months in a walk-in chamber set at 3 degrees Celsius above the current average temperature in northern Hebei and Inner Mongolia, the higher altitude provinces where potatoes are usually grown in China.

Their research, published in the journal Climate Smart Agriculture this month, found the higher temperatures accelerated tuber growth by 10 days, but cut potato yields by more than half.

Under current climate policies, the world is facing as much as 3.1 C of warming above pre-industrial levels by 2100, according to a United Nations report released in October.

Farmers in China say they are already feeling the effect of extreme weather events.

In Inner Mongolia, dozens of workers clutching white sacks rush to gather potatoes dug up from the soil before the next downpour.

“The biggest challenge for potatoes this year is the heavy rain,” said manager Wang Shiyi. “It has caused various diseases… and greatly slowed down the harvest progress.”

Meanwhile, seed potato producer Yakeshi Senfeng Potato Industry Company has invested in aeroponic systems where plants are grown in the air under controlled conditions.

Farmers are increasingly demanding potato varieties that are higher-yielding and less susceptible to disease, particularly late blight, which caused the Irish Potato Famine of the mid-19th century and thrives in warm and humid conditions.

“Some new and more aggressive (late blight) strains have begun to appear, and they are more resistant to traditional prevention and control methods,” said general manager Li Xuemin, explaining the Inner Mongolia-based company’s strategy.

The research by CIP, which is headquartered in Lima, is part of a collaborative effort with the Chinese government to help farmers adapt to the warmer, wetter conditions.

In the greenhouse outside Li’s lab, workers swab pollen on white potato flowers to develop heat-tolerant varieties.

Li says Chinese farmers will need to make changes within the next decade, planting during spring instead of the start of summer, or moving to even higher altitudes to escape the heat.

“Farmers have to start preparing for climate change,” Li said. “If we don’t find a solution, they will make less money from lower yields and the price of potatoes may rise.”

UNITED NATIONS — The U.N.’s children’s fund raised the alarm on Friday over the high rate of new HIV infections among young women and girls, warning they lacked access to prevention and treatment.

In a report ahead of world AIDS day on Sunday, UNICEF said that 96,000 girls and 41,000 boys aged 15-19 were newly infected with HIV in 2023, meaning seven out of 10 new adolescent infections were among girls.

In sub-Saharan Africa, nine out of 10 new HIV infections among 15- 19-year-olds were among girls in the most recent period for which data is available.

“Children and adolescents are not fully reaping the benefits of scaled up access to treatment and prevention services,” said UNICEF associate director of HIV/AIDS Anurita Bains.

“Yet children living with HIV must be prioritized when it comes to investing resources and efforts to scale up treatment for all, this includes the expansion of innovative testing technologies.”

As many as 77% of adults living with HIV have access to anti-retroviral therapy, but just 57% of children 14 and younger, and 65% of teenagers aged 15-19, can obtain lifesaving medicine.

Children 14 and younger account for only 3% of those living with HIV, but account for 12% — 76,000 — of AIDS-related deaths in 2023.

Around 1.3 million people contracted the disease in 2023, according to a report from the UNAIDS agency.

That is still more than three times higher than needed to reach the U.N.’s goal of ending AIDS as a public health threat by 2030.

Around 630,000 people died from AIDS-related illnesses last year, the lowest level since a peak of 2.1 million in 2004, the report said ahead of World AIDS Day on Sunday.

Much of the progress was attributed to antiretroviral treatments that can reduce the amount of the virus in the blood of patients.

Out of the nearly 40 million people living with HIV around the world, some 9.3 million are not receiving treatment, the report warned.

Cucumbers shipped to 13 U.S. states and five Canadian provinces have been recalled because of potential salmonella contamination, the Food and Drug Administration said this week.

SunFed Produce, based in Arizona, recalled the cucumbers sold between October 12 and November 26, the FDA said Thursday.

No illnesses were immediately reported. People who bought cucumbers during the window should check with the store where they purchased them to see if the produce is part of the recall. Wash items and surfaces that may have been in contact with the produce using hot, soapy water or a dishwasher.

Salmonella can cause symptoms that begin six hours to six days after ingesting the bacteria and include diarrhea, fever and stomach cramps. Most people recover without treatment within a week, but young children, people older than 65 and those with weakened immune systems can become seriously ill.

Earlier this summer, a separate salmonella outbreak in cucumbers sickened 450 people in the United States.

NYANGAMBE, ZIMBABWE — At first, the suggestion to try farming maggots spooked Mari Choumumba and other farmers in Nyangambe, a region in southeastern Zimbabwe where drought wiped out the staple crop of corn.

After multiple cholera outbreaks in the southern African nation resulting from extreme weather and poor sanitation, flies were largely seen as something to exterminate, not breed.

“We were alarmed,” Choumumba said, recalling a community meeting where experts from the government and the United States Agency for International Development, or USAID, broached the idea.

People had flocked to the gathering in hope of news about food aid. But many stepped back when told it was about training on farming maggots for animal feed and garden manure.

“People were like, ‘What? These are flies. Flies bring cholera,’” Choumumba said.

A year later, the 54-year-old walks with a smile to a smelly cement pit covered by wire mesh where she feeds rotting waste to maggots — her new meal ticket.

After harvesting the insects about once a month, Choumumba turns them into protein-rich feed for her free-range chickens that she eats and sells.

Up to 80% of chicken production costs were gobbled up by feed for rural farmers before they took up maggot farming. Many couldn’t afford the $35 charged by stores for a 50-kilogram (110-pound) bag of poultry feed, said Francis Makura, a specialist with a USAID program aimed at broadening revenue streams for farmers affected by climate change.

But maggot farming reduces production costs by about 40%, he said.

Black soldier fly

The maggots are offspring of the black soldier fly, which originates in tropical South America. Unlike the house fly, it is not known to spread disease.

Their life cycle lasts just weeks, and they lay between 500 and 900 eggs. The larvae devour decaying organic items — from rotting fruit and vegetables to kitchen scraps and animal manure — and turn them into a rich protein source for livestock.

“It is even better than the crude protein we get from soya,” said Robert Musundire, a professor specializing in agricultural science and entomology at Chinhoyi University of Technology in Zimbabwe, which breeds the insects and helps farmers with breeding skills.

Donors and governments have pushed for more black soldier fly maggot farming in Africa because of its low labor and production costs and huge benefits to agriculture, the continent’s mainstay that is under pressure from climate change and Russia’s war in Ukraine.

In Uganda, the maggots helped plug a fertilizer crisis caused by the war in Ukraine. In Nigeria and Kenya, they are becoming a commercial success.

In Zimbabwe

The Zimbabwean government and partners piloted it among farmers struggling with securing soya meal for their animals. A World Bank-led project later used it as a recovery effort for communities affected by a devastating 2019 cyclone.

Now it is becoming a lifesaver for some communities in the country of 15 million people where repeated droughts make it difficult to grow corn. It’s not clear how many people across the country are involved in maggot-farming projects.

At first, “a mere 5%” of farmers that Musundire, the professor, approached agreed to venture into maggot farming. Now that’s up to “about 50%,” he said, after people understood the protein benefits and the lack of disease transmission.

The “yuck factor” was an issue. But necessity triumphed, he said.

With the drought decimating crops and big livestock such as cattle — a traditional symbol of wealth and status and a source of labor — small livestock such as chickens are helping communities recover more quickly.

“They can fairly raise a decent livelihood out of the resources they have within a short period of time,” Musundire said.

Reduces waste, too

It also helps the environment. Zimbabwe produces about 1.6 million tons of waste annually, 90% of which can be recycled or composted, according to the country’s Environmental Management Agency. Experts say feeding it to maggots can help reduce greenhouse emissions in a country where garbage collection is erratic.

At a plot near the university, Musundire and his students run a maggot breeding center in the city of 100,000 people. The project collects over 35 metric tons a month in food waste from the university’s canteens as well as vegetable markets, supermarkets, abattoirs, food processing companies and beer brewers.

“Food waste is living, it respires and it contributes to the generation of greenhouse gases,” Musundire said.

According to the U.N. Food and Agriculture Organization, food loss — which occurs in the stages before reaching the consumer — and food waste after sale account for 8% to 10% of greenhouse gas emissions globally, or about five times that of the aviation sector.

The university project converts about 20 to 30 metric tons of the waste into livestock protein or garden manure in about two weeks.

Choumambo said people often sneer as she goes around her own community collecting banana peels and other waste that people toss out at the market and bus station.

“I tell them we have good use for it, it is food for our maggots,” she said. She still has to contend with “ignorant” people who accuse maggot farmers of “breeding cholera.”

But she cares little about that as her farm begins to thrive.

‘Sweet smell of food’

From bare survival, it is becoming a profitable venture. She can harvest up to 15 kilograms (about 33 pounds) of maggots in 21 days, turning out 375 kilograms (826.7 pounds) of chicken feed after mixing it with drought-tolerant crops such as millets, cowpeas and sunflower and a bit of salt.

Choumambo sells some of the feed to fellow villagers at a fraction of the cost charged by stores for traditional animal feed. She also sells eggs and free-range chickens, a delicacy in Zimbabwe, to restaurants. She’s one of 14 women in her village taking up the project.

“I never imagined keeping and surviving on maggots,” she said, taking turns with a neighbor to mix rotting vegetables, corn meal and other waste in a tank using a shovel.

“Many people would puke at the sight and the stench. But this is the sweet smell of food for the maggots, and for us, the farmers.”

geneva — The World Health Organization on Thursday urged countries to step up surveillance for bird flu after the first case was detected in a child in the United States. 

A small but growing number of H5N1 avian influenza infections have been detected in humans around the world in recent years, Maria Van Kerkhove, WHO epidemic and pandemic preparedness and prevention director,  said at a press conference. 

“What we really need globally, in the U.S. and abroad, is much stronger surveillance in animals: in wild birds, in poultry, in animals that are known to be susceptible to infection, which include swine, which include dairy cattle, to better understand the circulation in these animals,” she said. 

More outbreaks

H5N1 emerged in 1996, but since 2020, the number of outbreaks in birds has grown exponentially, alongside an increase in the number of infected mammals. 

The strain has led to the deaths of tens of millions of poultry, with wild birds and land and marine mammals also infected. 

Human cases recorded in Europe and the United States since the virus surged have largely been mild. 

In March, infections were detected in several dairy herds across the United States. 

U.S. health officials believe the risk for the general public is low, though albeit higher for those working directly with livestock, including birds, dairy cattle and more. 

Last Friday, U.S. authorities said a child in California had become the first in the United States to test positive for bird flu infection. Health officials offered checks and preventive treatment to exposed contacts at the youth’s child care center. 

The child had mild symptoms and was said to be recovering at home following treatment with flu antivirals. 

“Including this most recent case, 55 human cases of H5 bird flu have now been reported in the United States during 2024, with 29 in California,” the U.S. Centers for Disease Control and Prevention said. 

No human-to-human infections seen

Van Kerkhove said all but two of those had known exposure to infected animals. 

“We have not seen evidence of human-to-human infection. But again, for each of these human detected cases, we want to see a very thorough investigation taking place,” she said. 

“We need much stronger efforts in terms of reducing the risk of infection between animals to new species and to humans,” she added, notably through testing and proper protective equipment. 

Van Kerkhove, who was the WHO’s COVID-19 technical lead, stressed the importance of preparing “for when or if we will be in a situation where we are in a flu pandemic.” 

“We’re not in that situation yet, but we do need more vigilance,” Van Kerkhove said.

Geneva, Switzerland — A young South African activist living with HIV will take over Oscar-winning actress Charlize Theron’s Instagram account on World AIDS Day, the United Nations said Thursday.

Ibanomonde Ngema, a 21-year-old activist, will be given the reins to the South African-born actress’s global account @charlizeafrica, with some 7.6 million followers, on December 1, UNAIDS said in a statement.

The takeover by Ngema, who was born with HIV and has dedicated her advocacy work to dispelling myths and reducing stigma around HIV, will aim to bring awareness to the first-hand experiences of young people living with HIV, it said.

Theron, a so-called UN Messenger of Peace who has long advocated for tackling the systemic inequalities that drive HIV infections among young women and girls, insisted in the statement that “ending AIDS is within reach.”

But, she warned, “only if we completely dismantle harmful patterns of stigma and discrimination through laws, policies, and practices that protect people living with HIV.”

Theron won a best actress Oscar for her lead role in the 2004 film “Monster” and has more recently starred in pictures such as “Mad Max: Fury Road.”

“I have always loved watching Charlize Theron on the big screen and have long been inspired by her using her influence to help people around the world, especially in our home country of South Africa,” Ngema said in the statement.

The announcement came after UNAIDS this week released a new report that showed how rights violations exacerbate the vulnerability of women and girls to HIV.

Last year, women and girls accounted for 62% of all new HIV infections in sub-Saharan Africa, UNAIDS said.

HARARE, ZIMBABWE — Ahead of World AIDS Day on December 1, the U.N. has released a report saying that upholding human rights is essential for ending the AIDS pandemic.

The report says human rights violations, including discrimination against girls and women, and criminalization of LGBTQ+ people, obstruct efforts to end AIDS.

UNAIDS Executive Director Winnie Byanyima released a report online called “Take the Rights Path to End AIDS.”

The report says the world can meet the goal of ending AIDS by 2030 if leaders protect the human rights of everyone living with and at risk of HIV.

She said advances in medicine are helping reduce new cases of HIV.

“But big gaps still remain in the protection of rights. When there is impunity for gender-based violence; when people can be arrested for who they are, or who they love; when a visit to health services is dangerous for people because of their gender — the result is that people are blocked from care, this drives the AIDS pandemic,” she said. “Only rights can fix these wrongs. There is an urgent need to enact laws that protect the human rights of everyone.”

Zimbabwe was one of the countries hit hardest by HIV/AIDS until it introduced an AIDS levy in 1999, a 3% tax on income and business profits which is managed by the National AIDS Council.

Dr. Bernard Madzima, the executive officer of the Zimbabwe National AIDS Council, said the country is aiming to end HIV as a public health threat by the end of the decade. He said the country enforces a policy of no discrimination against HIV patients.

“In Zimbabwe there is no one who has been stigmatized whether they are HIV positive or whether they are HIV negative, they will get access. Our approach in HIV intervention is based on it being a public health approach,” he said. “So our interventions are to make sure that HIV is no longer a public health threat by 2030.”

Madzima said the government is also attempting to reach marginalized groups like sex workers, prison inmates and informal miners with care. In the past, Zimbabwean authorities targeted sex workers and organizations such as Gays and Lesbians of Zimbabwe.

The UNAIDS report noted that police only stopped arresting sex workers for “loitering” in 2015, after Zimbabwe Lawyers for Human Rights successfully argued in court that the police conduct was illegal. The report said the move has resulted in sex workers being able to seek health services.

The report commended Zimbabwe for stopping the criminalization of HIV transmission in 2022, adding that criminalization and stigmatization of marginalized communities obstruct access to life-saving HIV services.

JACKSON, Mississippi — Medical marijuana businesses in the southern U.S. state of Mississippi don’t have the right to advertise on billboards or other places because marijuana itself remains illegal under federal law, an appeals court says. 

The owner of a medical marijuana dispensary argued that the First Amendment protects the right to advertise because Mississippi law permits the sale of cannabis products to people with debilitating medical conditions. The state enacted its law in 2022. 

A three-judge panel of 5th U.S. Circuit Court of Appeals on Friday rejected the arguments about advertising. They cited the federal Controlled Substances Act, which since 1970 has prohibited the manufacture, distribution, dispensing and possession of marijuana. 

The federal law applies in all states, and Mississippi “faces no constitutional obstacle to restricting commercial speech relating to unlawful transactions,” the judges wrote. 

The Mississippi attorney general’s office praised the court decision for upholding “Mississippi’s reasonable restrictions on advertising for medical marijuana dispensaries by print, broadcast and other mass communications,” said the office spokesperson, MaryAsa Lee. 

Clarence Cocroft II operates Tru Source Medical Cannabis in the northern Mississippi city of Olive Branch. He sued the state in 2023 to challenge its ban on medical marijuana advertising on billboards or in print, broadcast or social media or via mass email or text messaging. 

“Upholding this ban makes it incredibly difficult for me to find potential customers and to educate people about Mississippi’s medical marijuana program,” Cocroft said in a statement Monday. “I remain committed to continuing this fight so my business can be treated the same as any other legal business in Mississippi.” 

The state allows medical marijuana businesses to have websites or social media accounts that provide information about their retail dispensing locations and a list of products available. It allows them to be listed in phone books or business directories and to display cannabis in company logos. The businesses can also sponsor not-for-profit charity or advocacy events. 

Cocroft is represented by the Institute for Justice, a nonprofit libertarian law firm. The firm said Monday that it was considering its next steps in the lawsuit, including possibly asking the entire appeals court to reconsider the case or an appeal to the Supreme Court. 

“Mississippi cannot on the one hand create an entire marketplace for the sale of medical marijuana, and on the other hand rely on an unenforced federal law to prohibit buyers and sellers from talking about it,” said Ari Bargil, an Institute for Justice attorney.
