EU Ambassadors Take Up Shovels to Make Point About Climate Change

Around the world, national leaders and diplomats have expressed their hopes that the United States will reverse its decision to pull out of the Paris Agreement on fighting climate change. In Washington, some others have chosen to act in small ways rather than wait. 
Ambassadors and aides from all 28 members of the European Union joined forces last week with volunteers from Casey Trees, a local conservation group, to plant trees in a Washington city park, hoping to earn goodwill and make a symbolic point with their labor. EU countries’ representatives joined National Park Service staff and volunteers from Casey Trees to plant oak, holly, tuliptree and American elm trees at Montrose Park in northwest Washington, Nov. 15, 2019.

(Natalie Liu/VOA)Estonian emissary Jonatan Vsevoiv, one of about a dozen ambassadors who took up shovels, said the effort “symbolizes the EU’s effort on the climate front.” He added that the oak tree he helped plant holds special meaning to his native Estonia, just as it does in the United States.”I would say this is a national tree. It symbolizes strength and longevity — and stability,” he said.Having spent half of the past decade in diplomatic posts in the U.S. capital, Vseviov added that Washington has become for him “almost like my second hometown. … I’m glad to do something that gives back to the city.”  The tree-planting effort was led by Ambassador Kirsti Kauppi of Finland, which currently holds the EU’s rotating presidency. (Natalie Liu/VOA)The tree-planting effort was led by Ambassador Kirsti Kauppi of Finland, which currently holds the EU’s rotating presidency. She said her nation has a special affinity for trees, given that 70% of its surface is covered by woods and that Finns basically “live in and outside of the forest.” 
Even as Finland is often imagined as a land of ice and snow, the trees in her Nordic country “have no problem surviving the winter,” she said. “Then we have a very nice summer, a lot of sunlight. That’s when the trees grow.”   
Eva Hunnius Ohlin, senior adviser for energy and environment at the Swedish Embassy, was laboring with two other female embassy staffers when Juan Urbano, the Spanish Embassy’s robust agricultural attaché, offered a hand. 
The self-sufficient women declined his offer, but Ohlin cheerily told Urbano he should not take it personally “because we had earlier turned down the Finnish ambassador.”  Eva Hunnius Ohlin, right, senior adviser for energy and environment at the Swedish Embassy, with two of her colleagues insisted on Swedish sovereignty in their planting effort. (Natalie Liu/VOA)On a more serious note, Ohlin told VOA that her embassy has been increasingly engaged on climate change with institutions on the city and state level, even as the federal administration is seen as retreating on the issue. 
The interest in the issue in the big coastal states such as New York and California is well known. But, Ohlin said, citizens are also active “in the middle of the country,” in states like Colorado. 

Mum Knows Best: Homemade Soup May Fight Malaria

Some soups may be good for more than just the soul.A new study suggests that certain homemade broths — made from chicken, beef or even just vegetables — might have properties that can help fight malaria.Researcher Jake Baum of Imperial College London asked children from diverse cultural backgrounds at state-funded Eden Primary School to bring in homemade clear soup broth from recipes that had been passed down across generations to treat fever.  The samples were filtered and incubated with cultures of Plasmodium falciparum, a parasite that accounts for an estimated 99.7%  of malaria cases in Africa, according to the World Health Organization (WHO).Of 56 soup samples tested, five were more than 50% effective in curbing growth of the parasite, two with similar success as one drug currently used to treat malaria, Baum and his team reported Tuesday in the Archives of Disease in Childhood.Four other soups were more than 50% effective at blocking parasites from maturing to be able to infect mosquitoes, which transmit the disease.”When we started getting soups that worked — in the lab under very restricted conditions, I should add — we were really happy and excited,” Baum told AFP in an email.But he noted that it was unclear which ingredients had the antimalarial properties.”If we were serious about going back and finding the magic ingredient, like good scientists, we’d have to do it in a very standardized way,” he said.The soups came from families from diverse ethnic backgrounds, including Europe, North Africa and the Middle East, and had a variety of base ingredients, including chicken, beef, beetroot and cabbage.Much to the pleasure of the vegetarians involved in the study, Baum noted, the veggie-only soups showed similar results to the meat-based ones.Baum said he had wanted to teach children the process through which scientific research can turn an herbal remedy into a synthetically produced medicine.He pointed to the success of Professor Dr. Tu Youyou of China, who in the 1970s was instrumental in isolating and extracting an antimalarial substance from quinhao, an herb used in Eastern medicine to treat fever for some two thousand years.This research led to the synthetic production of artemisinin — a drug now widely used to treat malaria — and won Tu the Nobel Prize in 2015.Emerging resistance to drugs treating the disease — which kills some 400,000 people a year — means scientists have to “look beyond the chemistry shelf for new drugs,” Baum noted in a press release.”The lesson from me was more that there may well be golden recipes out there in the world for disease that remain untapped.”

US House Panel Backs Marijuana Decriminalization

A divided U.S. House committee approved a proposal Wednesday to decriminalize and tax marijuana at the federal level, a vote that was alternately described as a momentous change in national cannabis policy and a hollow political gesture. The House Judiciary Committee approved the proposal 24-10 after more than two hours of debate. It would reverse a long-standing federal prohibition by removing marijuana from the Controlled Substances Act, while allowing states to set their own rules on pot. The vote marks a turning point for federal cannabis policy and is truly a sign that prohibition's days are numbered,'' Aaron Smith, executive director of the National Cannabis Industry Association, said in a statement. Cannabis Trade Federation CEO Neal Levine called the votea historic step forward for cannabis policy reform.” State measuresThe vote came at a time when most Americans live in states where marijuana is legal in some form, and committee members from both parties agreed that national cannabis policy lagged behind changes at the state level. That divide has created a host of problems. Loans and other banking services, for example, are hard to get for many marijuana companies because pot remains illegal at the federal level. The House bill’s future is uncertain. It wasn’t immediately clear if the proposal would be reviewed by other committees, nor was it clear when or whether a vote would take place in the full House. The proposal has better chances of passing in the Democratic-controlled chamber than in the Republican-held Senate. The House passed a bill earlier this year to grant legal marijuana businesses access to banking, but it hasn’t advanced in the Senate. Republicans on the House Judiciary Committee complained that the proposal to decriminalize cannabis had never had a hearing and lacked the bipartisan support needed to become law. It's going nowhere,'' said Representative Doug Collins, a Georgia Republican. Sales taxAmong its provisions, the legislation would authorize a 5% sales tax on marijuana products to fund programs aimed at assisting people and communities harmed in the battle against drugs, such as job training and legal aid. It also would require federal courts to expunge prior marijuana convictions. Committee Chairman Jerrold Nadler, a New York Democrat, said the nation has for too longtreated marijuana as a criminal justice problem, instead of a matter of personal choice and public health.” Arresting, prosecuting and incarcerating users at the federal level is unwise and unjust,'' he said.The racial disparity in enforcement of marijuana laws has only compounded this mistake with serious consequences, particularly for minority communities.” 

Australia Searches for African Swine Fever Vaccine

Australian scientists say it could be another five years before a vaccine is developed to protect pigs from African swine fever.  It is estimated that a quarter of the world’s pig population has died this year, following the deadly outbreak of the virus in China. African swine fever, or ASF, has yet to reach Australia, but it is close.  The virus has been spreading rapidly through Asia, and outbreaks have been reported in East Timor, one of Australia’s closest neighbors.Hong Kong Reports a Case of African Swine Fever

        A case of African swine fever has been detected in a Hong Kong slaughterhouse, prompting the culling of all 6,000 pigs at the facility.

Secretary for Food and Health Sophia Chan said in a statement Friday that the incurable virus was found in a single pig imported from a farm in Guangdong province in mainland China, where the monthslong outbreak has devastated herds.

Pork is China’s staple meat and its price and availability is considered a matter of national concern.

The disease is devastating pig populations in several countries.  It is highly contagious and there is no cure.Scientists have been working on a vaccine for 60 years, but because the African swine fever virus is so large and complex it is an immense task.At the Australian Animal Health Laboratory in the state of Victoria researchers are hopeful of a breakthrough, but concede an effective treatment for ASF could be at least five years away.China Reports Outbreak of African Swine Fever in Hunan

        China has reported a new outbreak of African swine fever that is threatening the country’s vital pork industry.

The Ministry of Agriculture and Rural Affairs reported Friday that the disease had been detected on a farm in Yongzhou in the central province of Hunan, where 4,600 pigs were being raised.

Although 171 of the pigs had died and 270 were found sick, ministry regulations require all pigs on an affected farm be culled and disposed of and the area quarantined and decontaminated.

1 million pigs…
The laboratory’s director is Dr Trevor Drew.“I do not think I really expected African swine fever to spread with such ferocity,” said Drew.  “I think we will not be able to control African swine fever until there is a vaccine available.”Without a vaccine, Australia will rely on traditional methods of disease control should ASF reach its shores.  Infected pigs would be culled, their carcasses buried and farms disinfected.Australia’s multi-million dollar pork industry includes about 2,700 producers, which employ 34,000 people.US Halts Polish Pork Imports Over African Swine Fever

        The United States suspended imports of pork from Poland Thursday because of an outbreak of the highly contagious hog disease African swine fever in that country.

African swine fever has spread rapidly in Eastern Europe and China, the world’s largest pork producer, where new cases are appearing and the disease is traveling far distances.

The United States is free of the disease and eager to keep it that way because infections in U.S.

There are concerns the disease could spread through Australia’s large feral pig population.  It numbers about 25 million, and the animals are spread across almost half the country.Scientists say the most likely way ASF could enter Australia is through infected pork products that are then fed to pigs.Under new bio-security laws, Australia is deporting tourists who fail to declare illegal pork products.

Nigerian Authorities Launch Campaign Against Open Defecation

Baba Awolu reports for work at 5 a.m. each day at a local toilet and washroom facility he owns in the Jahi district of Abuja.

Nov. 18, 2019. (Timothy Oviezu/VOA)”What we’re doing is helping people and the government,” Awolu said. “Instead of going to nearby bushes to defecate, they can use our facility and pay a token.” In  October a survey by the U.N. Children’s Fund named  Nigeria as the country with the most people practicing open defecation, passing India, which outlawed the practice.About 25 percent, or more than 47 million Nigerians, lack access to toilet facilities. The majority are in rural areas, where many poor people can’t afford to install toilets in their homes.The result is defecation in bushes and fields, leading to contaminated water supplies and the spread of disease.At an event in Abuja this week, Nigerian authorities said they are determined to end open defecation and achieve U.N. sanitation goals by 2025, five years ahead of schedule.Only 14 out of the 774 local government areas in Nigeria are open defecation-free, authorities say. The practice is more prevalent in north-central states, including Abuja, the capital.  Muhammad Mahmood is Nigeria’s environment minister.”This commitment is demonstrated by the president’s declaration of state of emergency on water, sanitation and hygiene in the country,” Mahmood said. “With just 11 years to go with the 2030 deadline, we must re-double our efforts to provide universal access to toilets, leaving no one behind.”An open defecation site in Abuja close to houses. (Timothy Obiezu/VOA)Some 87,000 young children in Nigeria die each year from illnesses linked to open defecation, poor sanitation and hygiene.That number may fall, however, as more places like Baba Awolu’s open across Nigeria, giving people regular access to working bathrooms and a boost to public sanitation. 

Bei Bei, Washington’s Eligible Bachelor Panda, Heads to China

After a month of preparations and goodbyes, Bei Bei, the Washington National Zoo’s most eligible giant panda bachelor, was on his way to China on Tuesday, where scientists hope he will help increase the population of his species.The departure of 4-year-old Bei Bei to his parents’ homeland had been pre-arranged and was announced last month by the zoo, where giant pandas have always been a visitor favorite.Bei Bei, which means “precious treasure,” munched his last American breakfast of bamboo and leaf eater biscuits early Tuesday before entering a custom travel crate that was loaded onto a truck for the trip to Dulles International Airport, the zoo said.From there, he began the 16-hour direct flight to Chengdu, China, aboard a dedicated Boeing 777F flown by FedEx and stocked with his favorite snacks, such as bamboo shoots, pears, and cooked sweet potatoes, it said.Workers look at a FedEx’s crate where Bei Bei, the giant panda, has been placed before his departure to China, at the Smithsonian’s National Zoo, in Washington, Nov. 19, 2019.”Today is bittersweet,” zoo Director Steve Monfort said. “We’ve cared for Bei Bei, and along with millions, watched him grow into a true ambassador for his species.”Visitors have spent the past few weeks getting their last looks as zookeepers got Bei Bei accustomed to his travel crate, first by training him to walk through it, then spending time inside with the door closed.Breeding programs are key to efforts to reintroduce pandas into the wild. Thanks to reforestation to expand habitats in which the species can survive, pandas have been reclassified from “endangered” to “vulnerable” by the International Union for the Conservation of Nature. There are an estimated 1,800 giant pandas in the wild.Mei Xiang and Tian Tian Bei Bei is not the first in his family to travel abroad. His parents, Mei Xiang and Tian Tian, arrived from China in 2000, and his older siblings Tai Shan and Bao Bao both packed their bags for China when they came of breeding age.Mei Xiang and Tian Tian are the zoo’s only remaining giant pandas.Zoo spokeswoman Pamela Baker-Masson did not rule out another breeding attempt, but added in an email that “Mei Xiang is of advanced maternal age so it is highly unlikely that she will have another cub.”An artificial insemination last year of Mei Xiang, who has been at the zoo for 20 years, failed to produce a cub.The zoo has collaborated with Chinese scientists on a breeding program since it received its first pandas in 1972 following President Richard Nixon’s visit to China.

Climate Change Puts North Africa in a Hot Spot

(Lisa Bryant/VOA)Sandwiched between an encroaching Sahara and a warming Mediterranean Sea, the region has seen a sharp drop in rainfall over the past half century—a trend experts say will likely intensify in the coming decades. Indeed, over the course of this century parts of North Africa as well as the Middle East might become uninhabitable, according to the German research and policy organization, the Max Planck Institute.“We’re seeing higher temperatures and increasing water stress,” says Essia Guezzi, climate and energy project officer for conservation group WWF North Africa, summing up some of the regional challenges. Meanwhile, rising sea levels threaten the region’s largely coastal populations, she and others note.A farmer in Bir Salah checks bark of an acacia tree, which produces coveted gum arabic. (Lisa Bryant/VOA)These and other issues will come into sharp focus during next month’s climate summit in Spain, a fellow member of the Mediterranean region that is considered a climate hotspot—more vulnerable to the effects of climate change than other parts of the world.
While Morocco has earned praise as a climate-change leader, the North African region overall needs to do much more to counter an otherwise grim future, experts say.

Many trees die and need to be replaced, while conflict in some Sahel countries makes areas inaccessible.“It doesn’t work 100 percent, but it works,” Boetsch says, adding a similar regional initiative could also work north of the Sahara. “The first problem is water. The second is getting communities to accept the projects.”Samira Sghaier arranges a shelf with her moringa products. She’s had a hard time finding buyers.

Women dominate the workforce. The projects have continued even after French financing ended. Participants are also making tourist handicrafts like palm leaf bags and hats, to earn extra revenue.“I think this is how, little by little, we can save the oases,” Guezguez says. “When local communities realize it’s in their interest to do so. 

US Asks Federal Judge to Toss Out Nevada Plutonium Lawsuit

The federal government wants a judge to reject Nevada’s request for a court order to remove weapons-grade plutonium from a site north of Las Vegas, arguing that officials have already promised that no more will be shipped to the state.
In documents filed Friday in U.S. District Court in Reno, the federal government brands as “conjectural” or “hypothetical” state claims that residents are harmed by radiation from the one-half metric ton of plutonium secretly trucked a year ago from South Carolina to Nevada.
The decision cannot be undone, the material is already in the state and the federal government has sovereign immunity, meaning the state can’t force the federal government to act, the motion contends.
The Department of Energy “routinely and safely transports nuclear materials into and out of Nevada and stores classified amounts of plutonium in Nevada,” it added.
State Attorney General Aaron Ford is pressing for the court order, saying the state was not informed of the shipments until they had already been made and can’t trust the federal agency to abide by after-the-fact promises.
“While we appreciate the Department of Energy’s new position that it will not ship additional plutonium here, a court order to this effect will hold the department accountable,” Ford said Monday in a statement.
The state maintains the Energy Department failed to conduct proper environmental reviews, and that an accident transporting, handling or storing the highly radioactive material could permanently harm Las Vegas, home to 2.2 million people and host to more than 40 million tourists a year.
“The long-term storage of this plutonium has exposed, and will continue to expose Nevada’s property, lands, water, air and citizens to greater radiological pollution and increased risk of ecological and economic catastrophe,” state attorneys said in documents filed Oct. 23.
The Energy Department disclosed last January that the plutonium had been taken in late 2018 to a specialized facility at the vast Nevada National Security Site, an area larger than the state of Rhode Island. The site was used to conduct nuclear weapons tests from 1945 to 1992.
The U.S. government had been ordered by a federal judge in South Carolina to remove a metric ton (2,204 pounds) of plutonium from the Savannah River nuclear weapons refining complex by 2020, and to remove another 5 metric tons (11,020 pounds) in future years.
The Energy Department says it plans to eventually move the plutonium to the Waste Isolation Pilot Plant in New Mexico. Outgoing Energy Secretary Rick Perry in April promised to send no more plutonium to Nevada and to remove the amount already delivered by 2027.
A spokeswoman for Democratic Sen. Catherine Marie Cortez Masto of Nevada said last week that Deputy Energy Secretary Dan Brouillette, President Donald Trump’s nominee to replace Perry, said he will abide by the department’s promise to remove the plutonium.

New and Old Drugs May Offer New Ways to Fight Heart Disease

Novel drugs may offer fresh ways to reduce heart risks beyond the usual medicines to lower cholesterol and blood pressure.One new study found that heart attack survivors benefited from a medicine long used to treat gout. Several experimental drugs also showed early promise for interfering with heart-harmful genes without modifying the genes themselves – in one case, with treatment just twice a year.The research was featured at an American Heart Association conference ending Monday in Philadelphia.”There’s a lot of excitement” about the new gene-targeting medicines, especially because they seem to last so long, said Dr. Karol Watson, of the University of California, Los Angeles.Scientists have been exploring gene therapy – altering DNA – to attack the root cause of many diseases. The new drugs essentially accomplish the same thing without tampering with genes, said the University of Pennsylvania’s Dr. Daniel Rader, who has consulted for some makers of these drugs.The medicines work by silencing or blocking messages that genes give to cells to make proteins that can do harm, such as allowing cholesterol to accumulate. The first few of these “RNA-interference” drugs recently were approved for other conditions, and research is also targeting heart disease.Farthest along is inclisiran, tested in 1,561 people with heart disease from clogged arteries who still had high LDL, the bad form of cholesterol, despite taking standard drugs. They were given a shot of inclisiran or a dummy drug when they joined the study, three months later and then every six months.The drug lowered LDL by 56% without serious side effects. More testing will show whether it also lowers heart attacks and other problems, not just cholesterol. Inclisiran’s maker, The Medicines Company, plans to seek federal approval for it later this year.Two other RNA interference drugs aim at a different target – triglycerides, another fat in the blood that’s elevated in one quarter of Americans. Treatments include very low-fat diets, weight loss, fish oil and drugs, but doctors say more and better therapies are needed.Each RNA interference drug was tested at various doses in 40 people. A single shot lowered triglycerides by 30% to 67%, and the benefit lasted for at least four months. The studies were just intended to show safety; Arrowhead Pharmaceuticals is developing both drugs.Other research found new benefits from older drugs. AstraZeneca’s Farxiga, originally developed to treat diabetes, also lowered the risk of heart problems in heart failure patients who did not have diabetes. Among 2,605 of such patients treated for 18 months, about 9% of those on Farxiga had worsening heart failure or heart-related death versus nearly 13% of those not given the drug. That worked out to a 27% lower risk, without extra serious side effects.Surprising benefits also were seen in a Canadian study of the decades-old gout drug. The anti-inflammatory drug colchicine – sold as Colcrys, Mitigare and in generic form – was tested in 4,745 people who recently had a heart attack.After about two years, colchicine users had a 23% lower risk of suffering a new heart attack, heart-related death, stroke, cardiac arrest or urgent need for an artery-opening procedure compared with a group given dummy pills. The benefit came mostly from preventing strokes and artery-opening procedures, and some heart doctors would rather have seen more difference in heart attacks and deaths.Colchicine is being tested in several other studies, and more evidence is needed before using it routinely to lower heart risks, Dr. L. Kristin Newby of Duke University wrote in a commentary published with the study in the New England Journal of Medicine.Dr. Donald Lloyd-Jones, a Northwestern University cardiologist and program chief for the heart conference, was more supportive.”When you have a safe drug that’s easily available, it’s going to be hard to hold this one back,” he said.

Hazardous Bushfire Smoke Blankets Sydney, Residents Warned to Stay Inside

Heavy winds stirred dozens of fires across Australia’s east coast on Tuesday, blanketing Sydney in hazardous smoke and prompting health warnings for the country’s most populous city.Wildfires have destroyed about 2.5 million acres (1 million hectares) of farmland and bush over the past couple of weeks, fuelled by tinder-dry conditions after three years of drought that experts say has been exacerbated by climate change.Strong winds fanned around 60 fires still ablaze across New South Wales (NSW) state and officials said smoke that stretched across Sydney was measured at 10 times above hazardous levels in some parts of the city.The NSW Rural Fire Service (RFS) said the smoke would linger for most of Tuesday as strong winds exacerbated the threat of more fires across Australia’s east coast.The state’s health department said people should stay inside as much as possible.”For most people, smoke causes mild symptoms like sore eyes, nose and throat. However, people with conditions like asthma, emphysema and angina are more likely to be sensitive to the health effects of smoke,” said Dr. Richard Broom, Director of Environmental Health at NSW Health.Australia’s bushfires are a common and deadly threat but the early outbreak of fires in the southern spring this year has already claimed at least four lives and destroyed more than 300 homes over the past week.NSW RFS said firefighters were working desperately to strengthen containment lines, with temperatures across the east coast set to soar for much of the week.”More than 1,300 firefighters are working on these fires, undertaking backburning operations and strengthening containment lines ahead of forecast hot, dry and windy weather, with seven areas under a total fire ban,” the RFS said in a statement.
