Climate change and habitat loss from big agriculture are combining to swat down global insect populations, with each problem making the other worse, a new study finds. While insects may bug people at times, they also are key in pollinating plants to feed people, making soil more fertile and they include beautiful butterflies and fireflies. Scientists have noticed a dramatic drop both in total bug numbers and diversity of insect species, calling it a slow-motion death by 1,000 cuts. Those cuts include pesticides and light pollution. Big single-crop agriculture that leaves less habitat and leafy food for bugs plus higher temperatures from climate change are huge problems for insects, but a new study in the journal Nature Wednesday based on more than 750,000 samples of 18,000 different species of insects says it’s not just those two threats acting on their own. It’s how habitat loss and climate change interact that really smashes bug populations. In about half the cases where numbers of insects had plummeted, researchers found climate change and habitat loss from agriculture magnifying each other. In more than a quarter of the cases of biodiversity loss, meaning fewer species, the same dynamic was at work. “We know insects are under threat. We’re now getting a much bigger handle on what they are threatened by and how much,” said study author Charlotte Outhwaite, an ecologist at the University College of London. “In this case, the habitat loss and climate change can often be worse than if they were acting …

The World Health Organization said on Saturday that at least one child death had been reported following an increase of acute hepatitis of unknown origin in children, and that at least 169 cases had been reported in children in 12 countries. The WHO issued the figures as health authorities around the world investigate a mysterious increase in severe cases of hepatitis — inflammation of the liver — in young children. The WHO said that as of April 21 acute cases of hepatitis of unknown origin had been reported in the United Kingdom, the United States, Spain, Israel, Denmark, Ireland, the Netherlands, Italy, Norway, France, Romania and Belgium. It said 114 of the 169 cases were in the United Kingdom alone. The cases reported were in children aged from 1 month to 16 years, and 17 had required liver transplantation, it said. It gave no details of the death that it said had been reported and did not say where it occurred. The WHO said a common cold virus known as an adenovirus had been detected in at least 74 cases. COVID-19 infection was identified in 20 of those tested and 19 cases were detected with a COVID-19 and adenovirus co-infection, it said. The WHO said it was closely monitoring the situation and working with British health authorities, other member states and partners. U.S. health officials have sent out a nationwide alert warning doctors to be on the lookout for symptoms of pediatric hepatitis, possibly linked with a cold virus, as …

Maggie Mulligan said her dogs could sense the panic while she and her husband packed them up, agonized over having to leave horses behind and fled a fast-moving wildfire barreling toward their home in northeast New Mexico.  “We don’t know what’s next,” she said. “We don’t know if we can go back to the horses.”  Mulligan and her husband, Bill Gombas, 67, were among the anxious residents who hurriedly packed up and evacuated their homes Friday ahead of ominous Western wildfires fueled by tinder-dry conditions and ferocious winds.  Over a dozen sizable fires were burning in Arizona and New Mexico, destroying dozens of homes and as of Saturday burning more than 174 square miles (451 square kilometers).  Winds that howled Friday remained a concern Saturday in northern New Mexico where two fires merged and quadrupled in size to a combined 66 square miles (171 square kilometers) in the mountains and grassland northwest of Las Vegas.  The merged fires burned some structures, but no figures were available, said fire information officer Mike Johnson. “They were able to save some structures and we know we lost other structures that we weren’t able to defend.”  Wind-blown clouds of dust and plumes of smoke obscured the skies near the fires, said Jesus Romero, assistant county manager for San Miguel County. “All the ugliness that spring in New Mexico brings — that’s what they’re dealing in.”  An estimated 500 homes in San Miguel were in rural areas of Mora and San Miguel counties covered by …

The number of women in Lebanon dying from pregnancy-related complications has nearly tripled amid a crushing three-year economic crisis that has seen doctors and midwives leave the country, the U.N. children’s agency UNICEF said Wednesday. The crisis is also affecting children, especially among Syrian refugees who have fled over the border into Lebanon. UNICEF said a third of children could not access health care by October 2021, and the number of children who die within the first four weeks after birth “increased dramatically among refugees in four provinces assessed, from 65 neonatal deaths in the first quarter of 2020 to 137 in the third quarter.” Lebanon hosts 1.5 million Syrian refugees, making up about a quarter of the population, according to official estimates. “Repeatedly, anguished parents and families are unable to access basic health care for their children“ as many dedicated health workers struggle to keep operations running during the crisis,” said Ettie Higgins, UNICEF Lebanon representative. Some 40% of doctors, including those that work specifically with children and women, have left the country, as well as some 30% of midwives, UNICEF said, diminishing the quality of services in a country formerly seen as a regional health care hub. “Lebanon had achieved remarkable success in reducing maternal deaths, but numbers rose again between 2019 and 2021, from 13.7 to 37 deaths per 100,000 live births,” the agency said in a report. It did not give the raw numbers. Faysal al-Kak, coordinator of Lebanon’s National Committee on Safe Motherhood, said the …

Authorities in Pakistan have confirmed the first case of wild polio virus in more than a year, dealing a setback to the country’s progress against the highly infectious disease. A 15-month-old boy was paralyzed by the virus in the turbulent North Waziristan district, which borders Afghanistan, according to an official announcement Friday. “This is, of course, a tragedy for the child and his family and it is also very unfortunate both for Pakistan and polio eradication efforts all over the world,” said Aamir Ashraf, a top health ministry official in Islamabad. “We are disappointed but not deterred.” Pakistan and neighboring Afghanistan are the only two countries where polio continues to paralyze children, although case numbers in recent years have significantly dropped on both sides of the border.  The last time a child was paralyzed in Pakistan was in January 2021. There is one wild polio virus infection reported in Afghanistan this year and four in 2021. Ashraf said health officials are conducting a thorough investigation into the detection of the polio case, and emergency immunization campaigns are underway to prevent further spread of the virus in the country of about 220 million people.  Pakistani Prime Minister Shehbaz Sharif’s office said he will chair an emergency meeting Monday of a national task force for polio eradication to review eradication efforts.   Polio crippled approximately 20,000 Pakistani children a year in the early 1990s. The latest case in Pakistan has raised to three the global number of polio infections in 2022, including …

A new case of Ebola has been confirmed in northwestern Democratic Republic of Congo, the National Institute of Biomedical Research said Saturday, four months after the end of the country’s last outbreak. The case, a 31-year-old male, was detected in the city of Mbandaka, capital of Congo’s Equateur province, the institute said. A health ministry spokesperson confirmed the discovery. The patient began showing symptoms on April 5 but did not seek treatment for more than a week. He was admitted to an Ebola treatment center on April 21 and died later that day, the World Health Organization (WHO) said in a statement. “Time is not on our side,” said Dr. Matshidiso Moeti, the WHO’s Regional Director for Africa.”The disease has had a two-week head start and we are now playing catch-up.” Mbandaka, a crowded trading hub on the banks of the Congo River, has contended with two previous outbreaks — in 2018 and in 2020. It is a city where people live in close proximity, with road, water and air links to the capital Kinshasa. The WHO said that efforts to contain the disease are already underway in Mbandaka, and that a vaccination campaign will begin in the coming days. Congo has seen 13 previous outbreaks of Ebola, including one in 2018-2020 in the east that killed nearly 2,300 people, the second highest toll recorded in the history of the hemorrhagic fever. The last outbreak, also in the east, infected 11 people between October and December and killed six of …

The World Health Organization warns the health system in eastern Ukraine has all but collapsed, putting the lives of thousands of people trapped in Mariupol and other besieged areas at risk.    U.N. health officials say it is critical they be granted immediate access to Mariupol and other areas hardest hit by fighting in eastern Ukraine. They say they have received reports that nearly all health facilities and hospitals in areas like the Luhansk region either are damaged or destroyed.   The WHO is appealing for access to affected areas to assess health needs and to provide critical medical supplies to the sick and injured. Speaking from Lviv in western Ukraine, WHO spokesman Bhanu Bhatnagar said the WHO so far has not been able to enter Mariupol and does not know the health status of the besieged population. Mariupol has been subjected to relentless bombing and shelling by Russian forces for the past two months. The city has been razed to the ground. Tens of thousands of people reportedly are living in underground bunkers, with limited food, water, and medical supplies. Bhatnagar said the WHO is moving supplies it thinks are needed in Mariupol closer to the city. But he added it is essential that a safe passage is created quickly. “We need a cessation of fighting for at least two days in order to move vital supplies in, but also assess the health needs,” he said. “We anticipate the worst. A health system that has collapsed completely and that brings with …

Devastating floods in South Africa this week, as well as other extreme weather events across the continent linked to human-caused climate change, are putting marine and terrestrial wildlife species at risk, according to biodiversity experts.  Africa has already faced several climate-related woes in the past year: the ongoing fatal floods follow unrelenting cyclones in the south, extreme temperatures in western and northern regions, and a debilitating drought which is currently afflicting eastern, central and the Horn of Africa.  Conservation and wildlife groups say it’s critical to protect species from these climate change-related weather events.  “Climate change is disrupting ecosystems and affecting the survival and suitability of species to live in their usual habitats,” said Shyla Raghav, who heads the climate change division at Conservation International. “Massive disruption to ecological stability will occur if adequate adaptation and mitigation measures are not implemented. There is need to incorporate climate proofing of our protected areas. That way we boost nature’s ability for resilience.”  Multiple species, including Africa’s famed “big-five” land animals and other terrestrial and marine life, are vulnerable to significant population loss. Ornithologist Paul Matiku, who heads the biodiversity watch group Nature Kenya, says shifting rainfall patterns and increased temperatures are having serious consequences for bird populations.  “Climate change causes seasonal variability in rainfall, temperature and food for birds. As such breeding aborts and bird populations automatically reduce over time,” Matiku said. “Wetland birds are affected by reducing water levels due to droughts. The Sahara Desert gets hotter, and some migratory birds …

Most Americans support a flexible approach to the lingering COVID-19 pandemic, with cities reimposing mask mandates when cases surge, even as a growing number are eager to get on with their lives, a Reuters/Ipsos poll completed Friday found. The results of the two-day poll illustrate the balancing act facing U.S. officials as they navigate a health crisis that will not go away. Sixty-four percent of U.S. adults — including 83% of Democrats and 46% of Republicans — said cities and states should impose mask mandates for indoor public places if there is a resurgence of COVID-19 in their area, the poll found. At the same time, 44% of respondents said that Americans need to get back to normal and get on with their lives, up from 36% in a poll completed in early February. The tension between the two sentiments was apparent this week in Philadelphia, which on Monday became the first major U.S. city to reimpose a mask mandate in settings including restaurants, schools and businesses following a rise in local COVID-19 cases, only to reverse course days later. City officials in Philadelphia, which like most big American cities is run by Democrats and overwhelmingly voted for Biden in the 2020 presidential election, on Thursday said decreasing hospitalizations and a leveling of case counts warranted a recommendation that residents wear masks in indoor public spaces, rather than a mandate. The city is the largest in the state of Pennsylvania, which will be a key battleground in November 8 midterm …

Environmentally, the planet was on a downward slide well before the U.N. General Assembly adopted a resolution designating April 22 in 2009 as International Mother Earth Day. The aim of this day is to celebrate the wonders of Mother Earth. The day also is meant to shed light on the issues threatening the health of the world’s ecosystems to ensure their survivability. Unfortunately, says U.N. Secretary-General Antonio Guterres, humans have been poor custodians of our fragile planet, which is facing a triple planetary crisis. “Climate disruption. Nature and biodiversity loss. Pollution and waste. The triple crisis threatening the well-being and survival of millions of people around the world. The building blocks of happy, healthy lives—clean water, fresh air, a stable and predictable climate—are in disarray, putting the Sustainable Development Goals in Jeopardy.” Ecosystems support all life on Earth. A healthy ecosystem depends on a healthy planet. Yet, scientists warn the planet is losing 4.7 million hectares of forests every year. They estimate around one million animal and plant species are now threatened with extinction. And, the warming of the planet, they say, could lead to a climate disaster, rendering the planet uninhabitable. Despite the dire outlook, Guterres says not all is lost. He says there is still hope of saving Earth if nations act together to tackle the problems that are endangering the well-being of the planet. He notes much has been accomplished since the global environmental movement started 50 years ago at a conference in Stockholm, Sweden. He says …

U.S. President Joe Biden has chosen Earth Day on Friday to sign an executive order to protect some of the country’s largest and oldest trees. The order the president is scheduled to sign in Washington State will require the Forest Service, the Bureau of Land Management and the National Park Service to identify threats to older trees, such as wildfire and climate change, and develop policies to safeguard them. Old trees are an ally in fighting climate change because they absorb large amounts of carbon dioxide, which contributes to global warming.  Scientists say redwood forests are among the world’s most efficient means of removing and storing carbon dioxide.  Thousands of U.S. redwoods have been destroyed in recent years. Biden’s order will require federal land managers to define and count mature and old-growth forests nationwide within a year. The measure is a safeguard designed to protest U.S. forests that have been decimated by fires, drought, and blight in recent years. Some information in this report came from the Associated Press and Reuters. …

Australia’s most populous states will on Friday abolish a raft of coronavirus rules, including compulsory isolation for close contacts. Some vaccine mandates for key workers will also be scrapped.  Health officials in New South Wales and Victoria say the overhaul to the rules is a “big step” and is part of a plan to “co-exist with COVID-19.” The new policy is a major overhaul of coronavirus restrictions for more than half of the Australian population. Those who may have come into close contact with COVID-19 in the states of New South Wales and Victoria will no longer have to isolate for seven days. They must, however, wear a mask indoors and be tested regularly. They also need special permission to visit hospitals, nursing homes or prisons. Many business leaders said the quarantine measures were too strict because they forced workers who weren’t infected to stay at home. “We get to put COVID in the rear-view mirror and finally leave the baggage of restrictions, isolations, and check-ins behind us. It means that the maximum available staff will now be with us,” said Paul Guerra, chief executive of the Victorian Chamber of Commerce. Health authorities in Australia say a recent omicron wave has peaked and that many restrictions can be lifted because more than 95% of the population has received at least two doses of a COVID-19 vaccination. However, Nancy Baxter, a clinical epidemiologist at Melbourne University, told the Australian Broadcasting Corp. that it is too soon to end mandatory isolation for …

Every year on Earth Day — April 22 — people come together to raise awareness about environmental problems. And this year they will focus on accelerating the transition to a prosperous green economy.     During the event, also known as International Mother Earth Day, some 1 billion people in 190 countries take part in activities that often include planting trees, removing litter from land and water sites, and educating others about the environment.     As curtailing climate change remains at the forefront of the global environmental agenda, Earth Day this year focuses on a business aspect of that goal: investing in our planet.    More businesses need to be pulled into the effort to safeguard the planet, especially to fight climate change, according to the Washington-based nonprofit Earthday.org.    According to the Earthday.org website, “Smart companies are discovering that they no longer have the choice between going green and growing long term profits — sustainability is the path to prosperity.”     “If you want to solve climate change, follow the money, because the money is overwhelmingly moving into technological solutions, research and development, all of which are green,” Earthday.org President Kathleen Rogers told VOA in an interview.   Oil and gas companies that rely on fossil fuels are feeling the pressure.    Companies that don’t go green face a “giant risk,” Rogers cautioned, because the outcry to curb fossil fuels continues to grow.    Climate scientist Michael Mann at Pennsylvania State University agreed, saying that “the transition towards …

A U.K. patient with a severely weakened immune system had COVID-19 for almost a year and a half, scientists reported, underscoring the importance of protecting vulnerable people from the coronavirus. There’s no way to know for sure whether it was the longest-lasting COVID-19 infection because not everyone gets tested, especially on a regular basis like this case. But at 505 days, “it certainly seems to be the longest reported infection,” said Dr. Luke Blagdon Snell, an infectious disease expert at the Guy’s & St. Thomas’ NHS Foundation Trust. Snell’s team plans to present several “persistent” COVID-19 cases at an infectious diseases meeting in Portugal this weekend. Their study investigated which mutations arise — and whether variants evolve — in people with super long infections. It involved nine patients who tested positive for the virus for at least eight weeks. All had weakened immune systems from organ transplants, HIV, cancer or treatment for other illnesses. None were identified for privacy reasons. Repeated tests showed their infections lingered for an average of 73 days. Two had the virus for more than a year. Previously, researchers said, the longest-known case that was confirmed with a PCR test lasted 335 days. Persistent COVID-19 is rare and different from long COVID. “In long COVID, it’s generally assumed the virus has been cleared from your body but the symptoms persist,” Snell said. “With persistent infection, it represents ongoing, active replication of the virus.” Each time researchers tested patients, they analyzed the genetic code of the virus …

Scientists have successfully bred a threatened species of coral as part of a project that hopes to restore damaged reefs off the coast of Florida that are under threat by a relatively new disease, a coral rescue organization said on Thursday. Reefs in Florida and the Caribbean are facing growing threat of destruction by the Stony Coral Tissue Loss Disease that strips coral of its color and ultimately its life altogether. The Florida Coral Rescue Center has in recent weeks bred hundreds of new coral of a species called rough cactus coral at a 185.80-square-meter facility that houses a total of 18 Florida coral species that are threatened by the disease. “There is potential to propagate these corals… on a level, that you could return some of these corals to the wild,” said Justin Zimmerman, Florida Coral Rescue Center supervisor, in an interview. “And there’s a potential that you could save the species by doing that.” Stony Coral Tissue Loss Disease was first observed near Miami in 2014 and by 2017 had spread to Florida’s northernmost reef tract and later past Key West to the south. Species that fall victim to it have a mortality rate of 66-100%, making it deadlier than the better-known coral bleaching phenomenon that is typically caused by higher water temperatures associated with climate change. The Florida Coral Rescue Center is managed by SeaWorld, a marine animal theme park company, and funded in part by the Disney Conservation Fund. Stony Coral Tissue Loss Disease represents another …

Palestinian militants fired a rocket into southern Israel for the first time in months on Monday, in another escalation after clashes at a sensitive holy site in Jerusalem, a series of deadly attacks inside Israel and military raids across the occupied West Bank. Israel said it intercepted the rocket, and there were no immediate reports of casualties or damage. Israel holds Gaza’s militant Hamas rulers responsible for all such projectiles and usually launches airstrikes in their wake. It was the first such rocket fire since New Year’s Eve. Early Tuesday, Israeli fighter jets carried out a series of airstrikes in southern Gaza Strip, targeting a “weapons manufacturing site” for Hamas, the Israeli military said. There were no reports of injuries. Hours earlier, the leader of the Islamic Jihad militant group, which boasts an arsenal of rockets, had issued a brief, cryptic warning, condemning Israeli “violations” in Jerusalem. Ziad al-Nakhala, who is based outside the Palestinian territories, said threats to tighten an Israeli-Egyptian blockade on Gaza imposed after Hamas seized power 15 years ago “can’t silence us from what’s happening in Jerusalem and the occupied West Bank.” However, no Palestinian group claimed responsibility for the rocket fire. Palestinians and Israeli police clashed over the weekend in and around the Al-Aqsa Mosque compound in Jerusalem, which has long been an epicenter of Israeli- Palestinian violence. It is the third holiest site in Islam and the holiest for Jews, who refer to it as the Temple Mount because the mosque stands on a …

The flight debut of NASA’s mega moon rocket faces additional delays following a string of failed fueling tests.  Officials said Monday it will be challenging to meet a launch window in early to mid-June. The next opportunity to send an empty capsule to the moon on a test flight would be at the end of June or July.  The 30-story Space Launch System rocket has been on the pad at Kennedy Space Center for the past month. It will return to the hangar next week for valve and fuel leak repairs. The problems cropped up earlier this month, preventing NASA from filling the rocket’s fuel tanks for a critical dress rehearsal.  The rocket will likely spend weeks in the hangar before heading back to the pad for a testing redo, said launch director Charlie Blackwell-Thompson.  Managers are considering various options for getting back on track.  “It’s just a matter of what’s the right time, what’s the right way to do that,” said Tom Whitmeyer, a NASA deputy associate administrator.  NASA wants this test flight under its belt before putting astronauts on board for the second launch, a lunar flyaround targeted for 2024. The third mission would attempt to land astronauts on the moon around 2025, more than a half-century after NASA’s Apollo moonshots.  …

Three Chinese astronauts returned to Earth on Saturday after six months aboard their country’s newest orbital station in the longest crewed mission to date for China’s ambitious space program. The Shenzhou 13 space capsule landed in the Gobi desert in the northern region of Inner Mongolia, shown live on state TV. During the mission, astronaut Wang Yaping carried out the first spacewalk by a Chinese woman. Wang and crewmates Zhai Zhigang and Ye Guangfu beamed back physics lessons for high school students. China launched its first astronaut into space in 2003 and landed robot rovers on the moon in 2013 and on Mars last year. Officials have discussed a possible crewed mission to the moon. On Saturday, state TV showed images from inside the capsule as it traveled at 200 meters per second over Africa before entering the atmosphere. The trio were the second crew aboard Tiangong, or Heavenly Palace. Its core module, Tianhe, was launched in April 2021. Plans call for completing construction this year by adding two more modules. Authorities have yet to announce a date for launching the next Tiangong crew. China is excluded from the International Space Station due to U.S. unease that its space program is run by the ruling Communist Party’s military wing, the People’s Liberation Army. China was the third nation to launch an astronaut into space on its own after the former Soviet Union and the United States. Tiangong is China’s third space station following predecessors launched in 2011 and 2016. The …
