Using austerity economics to crush UK inflation would be a cure worse than the disease

For more than a year Britain has been trapped with the highest inflation rate in four decades. Rather than making serious inroads to shift this uncomfortable fact, the past month’s economic developments have turned the country to panic.

The view in the City is the Bank of England has lost control. After a parade of bad news, leaving it backed into a corner, the central bank’s latest rate increase was as much a plea to financial markets to be taken seriously again as it was an inflation-busting tactic.

Over in Westminster, the government has invited half of corporate Britain for tea, biscuits, and crunch talks on Downing Street in an effort to appear “100% on it”, as Rishi Sunak’s once surefire bet to halve inflation this year risks lying in tatters.

Both camps have seen their credibility shattered in the past month, as financial markets bet that a recession is the price Britain must pay to tame the inflation beast stalking the nation. But while there are clear and obvious problems with soaraway prices, this is a trade-off the country mustn’t embrace lightly.

Across the economy the fallout from 13 consecutive interest rate rises in less than two years grows clearer by the day. Millions of mortgage holders are facing a surge in their borrowing costs, adding to the strain on household finances. Next come the nation’s water utilities, drowning in debt after years of reckless borrowing, plunging Thames Water into crisis. With interest rates expected to hit 6% by Christmas, this trickle of bad news could rapidly become a flood.

In the inflation hysteria of the past fortnight, concerns over the impact of rising interest rates were given a back seat as the government and central bank scrambled to restate their authority. Yet there is a growing danger: lacking credibility, might the reaction for monetary policy – what the Bank does – and fiscal policy – what the Treasury does – be to oversteer?

The big concern is that, despite the lessons of the 2008 financial crisis, austerity economics is back with a bang in the name of fighting inflation. It would be a cure far worse than the disease.

More economists are sounding the alarm over this risk.

Andy Haldane, the former Bank of England chief economist, had been held up by monetary policy hawks as an important Cassandra of the current mess. But although he went against the grain to call for higher rates in early 2021, he now advocates a pause.

There are good reasons for caution. Most of the impact from previous interest rate increases has yet to be felt, largely because of the nature of Britain’s mortgage market. With most people buying at least a two-year fixed rate mortgage, there is a lengthy delay, typically of about 18 months, before monetary policy bites.

Nowhere is this more clearly seen than in Britain’s ticking mortgage timebomb – where 2.5 million mortgage holders will reach the end of cheap fixed-rate deals before the end of next year. A typical borrower will be hit with a £2,900 annual rise in their repayments, according to the Resolution Foundation, sucking a total £15.8bn of spending power out of the economy by 2026.

While inflation has remained higher than anticipated in recent months, it has not been by a significant margin. Rather than a fall to 8.4% in May, inflation stuck at 8.7% was of course a worrying signal of inflation persistence. But there are dangers in setting too much store in short-term developments, if the long-term path back towards the Bank’s target level of 2% remains intact.

One reason UK inflation has proven stubbornly high should fade this week. Millions of households will see a modest fall in their gas and electricity bills from July after the reduction in the Ofgem energy price cap to £2,074 a year for a typical household – down from the £2,500-a-year level set by the government’s energy price guarantee.

Although still eye-wateringly high, the consultancy Capital Economics expects the development to subtract about one percentage point from overall CPI inflation in July. It expects a sharp fall in the headline rate to 6.7% for the month.

Inflation in food and drink should fade, too, from the highest levels since 1977, as declines in global agricultural commodity prices feed through to the supermarket shelves. Elsewhere, producer price inflation – measuring factory gate prices – is now below 3%, helped by falling wholesale energy prices. This should, in time, feed through to consumer prices.

Most economic forecasters expect inflation will fall back closer to 4-5% by the end of this year, before dropping near 2% by the end of 2024. That is still consistently higher than the Bank’s 2% target rate but there is more danger in rushing to hit that target over the short-term than taking a more flexible approach.

The focus should be on bolstering the productive capacity of the economy, not dismantling it

To be sure there are factors pushing in the opposite direction, particularly in the labour market, where Brexit and underinvestment in healthcare, skills and training are adding to the inflationary impetus. With near-record job vacancies unfilled, companies are putting up wages.

However, a breakdown on the supply side of the economy is a fairly poor excuse for tighter fiscal and monetary policy to crush demand.

The Bank has freely acknowledged in the past it is powerless to address these problems. For the government, there can be no good to come from further restraint in public sector pay, when the NHS and other public services are already at breaking point. In the face of persistent inflationary pressures, the focus should be on bolstering the productive capacity of the economy, not dismantling it.

Instead of panic over short-term inflation risks, there is a need for cool heads to prevail. A scorched-earth approach to tackling inflation would be too heavy a price to pay.

Almost 13 million adults now struggling to pay bills, debt charity warns

The number of UK households struggling with heavy debt has increased by two thirds since 2017, according to new analysis. Debt Justice, a charity that campaigns against unjust debt, has found that about 12.8 million adults in the UK are falling behind on bills or finding repayments a heavy burden. It is calling for urgent action to prevent people being “trapped in poverty”.

The findings come after the Bank of England increased interest rates to 5% last month, the highest level for 15 years. Financial markets now expect the Bank to raise rates to as much as 6.25% by the end of the year.

Heidi Chow, executive director of Debt Justice, said: “The government is turning a blind eye to the colossal household debt crisis that is engulfing millions of people at breakneck speed.


“Instead of ignoring the problem, they need to raise incomes, boost the protections for people in arrears and write off the unpayable debts to give everyone that needs it a fresh start.”

The Financial Conduct Authority’s (FCA) financial lives tracking survey in 2017 found 7.7 million adults in the UK were then over-indebted, which meant they had missed payment for credit commitments for three or more months or were finding bills a heavy financial burden.

The numbers struggling with debt in the UK rose to 9.6m in the May 2022 survey and 12.8m in January this year. Debt Justice says there is not enough support for people struggling with debt during the cost of living crisis.

A 47-year-old community worker from east London who provided a statement to the charity about the impact of debt said: “My health started deteriorating and I had to have a major operation. Afterwards I needed time off work to recuperate, so my pay went down even further. My debt started spiralling and eventually it reached £15,000.

Related: Rip-off Britain: why everything we buy now costs a fortune

“I took out credit cards and loans. I tried everything possible to pay off the debt that was building up. I was put in an impossible situation.”

One of the options for people struggling with debt is an individual voluntary arrangement (IVA), which is a formal and binding agreement to pay back debts to creditors over a certain period. In 2022, 87,967 IVAs were registered in England and Wales, the highest number since 1990.

There have been concerns that unscrupulous companies have been targeting people with large debts to promote IVAs. Citizens Advice has warned that some firms had been “preying on and profiting” from people struggling with debt.

The FCA announced last month that it was banning companies from receiving referral fees from debt solution providers. It found examples of customers in financial hardship who were recommended IVAs that would have caused greater harm.

One homeless person was recommended an IVA costing £6,000, when they could have been debt free in one year for £90 with a debt relief order, a low-cost debt remedy aimed at people with relatively low levels of debts.

Debt Justice warns that the cost of living crisis and high interest rates risk trapping people in poverty and acting as a drag on the economy for years to come. It wants a new strategy from the government to address the crisis including a freeze on all evictions and bailiff action to enforce household bills.

Kenya's President Ruto lifts six-year logging ban despite environmental concerns

Kenyan President William Ruto announced Sunday the lifting of a near six-year ban on logging, despite the concerns of environmental campaigners.

Ruto said the move was "long overdue" and was aimed at creating jobs and opening up sectors of the economy that rely on forest products.

"We can't have mature trees rotting in forests while locals suffer due to lack of timber. That's foolishness," he said at a church service in Molo, a town about 200 kilometres (120 miles) northwest of the capital Nairobi.

"This is why we have decided to open up the forest and harvest timber so that we can create jobs for our youth and open up business."

Ruto, who has positioned himself at the forefront of African efforts to combat climate change, said the government would push ahead with plans to plant 15 billion trees over 10 years.

The end of the ban is likely to delight saw millers and timber merchants who protested that it had caused major job losses.

Labour pledges bonus for new teachers but no commitment to 6.5% pay rise

SIR KEIR'S RED TORIES

Bridget Phillipson
Shadow Education Secretary.



Labour will unveil its education offer this week with a promise to pay new teachers a £2,400 retention bonus and pledge to cut billions spent on agency workers, but has refused repeatedly to commit to giving teachers a 6.5% pay rise.

Keir Starmer, the Labour leader, will set out his “mission” on schools aimed at improving school standards and extending childcare to pre-schoolers later in the week.

Ahead of that announcement, Bridget Phillipson, the shadow education secretary, unveiled a promise of a £2,400 bonus for newly qualified teachers who stay in post for two years in a bid to halt the retention crisis.

She also pledged to reduce payments to teaching agencies to fill growing vacancies, in response to new analysis by the party that found state schools in England have paid recruitment agencies more than £8bn since 2010.

According to the latest data, there were 43,997 leavers in the teaching profession in 2021-22, compared with 36,159 new starters.

Phillipson said: “We will only drive … rising standards in our classrooms if we get a grip on the perfect storm in our teaching profession, which is seeing an exodus of experienced teachers and costing taxpayers over the odds to fill vacancies.”

However, she would not be drawn about whether Labour would give teachers a pay rise in line with a recommendation from the pay review body – believed to be 6.5%.

“I would see that as the starting point for negotiation; we can’t get anywhere unless we’re prepared to negotiate,” she told the BBC’S Sunday with Laura Kuenssberg, adding: “I’m not going to come on this programme and commit to a figure, I wouldn’t expect the secretary of state to do that either; that is what will happen during the course of a negotiation.”

She added: “Labour governments always want to prioritise education and make sure we properly support people working in teaching with fair and affordable pay settlements.

“But who knows what the situation will be if we win that election, because the Conservatives crashed the economy, have behaved utterly recklessly, and that will present some tough choices.”

Teachers are set to strike again this week on Wednesday and Friday after rejecting a 4.5% increase offered by the government. The government is refusing to publish the teachers’ pay body recommendation.

Dr Mary Bousted, the joint general secretary of the National Education Union, welcomed the Labour plan as she warned of a “crisis point” in schools.

Related: Labour says government has created ‘perfect storm’ in England’s teaching workforce

But she added: “We want Labour to go much further, with better salaries for experienced teachers as well. Teachers are leaving the profession in droves – 40,000 left last year, 9% of teachers, 8% of headteachers last year. It’s experience we are missing in the profession.” She told Sky’s Sophy Ridge on Sunday that she had “no sympathy” with the government and Bank of England’s position that public sector pay rises are inflationary.

Paul Whiteman, the general secretary of the National Association of Head Teachers, welcomed the announcement but echoed calls for Labour to do more.

“Plans to improve early career training and ongoing professional development are sensible but Labour will need to be prepared to go further if they are to begin to solve the current crisis.

“We know that issues such as uncompetitive pay and a punitive inspection system are key factors in pushing people out of the profession, and it is only by tackling these that we will see teaching and school leadership become an attractive proposition once again.”

Danish researchers solve the mystery of how deadly virus hide in humans

Danish researchers solve the mystery of how deadly virus hide in humans

With a new method for examining virus samples researchers from the University of Copenhagen have solved an old riddle about how Hepatitis C virus avoids the human body's immune defenses. The result may have an impact on how we track and treat viral diseases in general.

An estimated 50 million people worldwide are infected with with chronic hepatitis C. The hepatitis C virus can cause inflammation and scarring of the liver, and in the worst case, liver cancer.   Hepatitis C was discovered in 1989 and is one of the most studied viruses on the planet. Yet for decades, how it manages to evade the human immune system and spread through the body has been a riddle – one that Danish researchers have become the first to solve.

A new method for examining virus samples has led researchers at the University of Copenhagen and Hvidovre Hospital to the answer, which is: the virus just puts on a 'mask'.

By donning a mask, the virus can remain hidden while making copies of itself to infect new cells. The mask cloaks the virus in the form of a molecule already in our cells. Disguised by the molecule, our immune systems confuse the virus with something harmless that needn't be reacted to.  

"How the Hepatitis C virus manages to hide in our liver cells without being detected by the immune system has always been a bit of a mystery. Our revelation of the virus’ masking strategy is important, as it could pave the way for new ways of treating viral infections. And it is likely that other types of viruses use the same trick," says Associate Professor Jeppe Vinther of the Department of Biology, who together with associate professor Troels Scheel and professor Jens Bukh from Copenhagen Hepatitis C Program headed the research.

The study has just been published in the scientific journal Naturehttps://www.nature.com/articles/s41586-023-06301-3

Camouflage for a malicious virus

The mask used by the hepatitis virus to hide in our cells is called FAD, a molecule composed of Vitamin B2 and the energy carrying molecule ATP. FAD is vital for our cells to convert energy. The FAD molecule’s importance and familiarity to our cells makes it ideal camouflage for a malicious virus.

For several years, the research team had a good idea that FAD was helping the virus hide in infected cells, but they lacked a clear way to prove it. To solve the challenge, they turned to Arabidopsis, a well-known experimental plant among researchers.

"We were getting desperate to find a way to prove our hypothesis, which is when we purified an enzyme from the Arabidopsis plant that can split the FAD molecule in two," explains Anna Sherwood from Department of Biology, who together with Lizandro Rene Rivera Rangel are first authors of the study.

Using the enzyme, the researchers were able to split the FAD and prove that the hepatitis C virus used it as a mask. 

Other viruses probably use the same trick

Like both the coronavirus and influenza virus, Hepatitis C is an RNA virus. Its genetic material consists of RNA that must be copied once the virus enters its host organism. New RNA copies are used to take over new cells, and one end of the RNA’s genetic material is masked by the FAD.

According to Jeppe Vinther, it is very realistic that other RNA viruses use similar masking techniques to spread without being detected by cellular control systems. In fact, researchers have already found another virus that uses the same strategy. And there are likely more.

"All RNA viruses have the same need to hide from the immune system and there is a good chance that this is just the beginning. Now that we’re attuned to this trick, it opens up the possibility of developing new and perhaps improved methods of tracking and treating viral infections in the future," concludes Jeppe Vinther.  

The research is funded by Independent Research Fund Denmark, as well as several other Danish and European foundations and conducted in a collaboration between Jeppe Vinther's research group at the Department of Biology, University of Copenhagen, and Troels Scheel and Jens Bukh's research groups from the Copenhagen Hepatitis C Program, which are located at UCPH’s Department of Immunology and Microbiology and the Department of Infectious Diseases at Hvidovre Hospital.

A trio of ethologists at the University of Pisa has documented and analyzed an instance of infant cannibalism in a drill monkey. In their paper published in the journal Primates, Grazia Casetta, Andrea Paolo Nolfo and Elisabetta Palagi describe the scenario recorded on videotape and offer possible explanations for the behavior they witnessed.

Observations of instances of infant cannibalism in  is rare—when it has been observed, it has almost always been of a mother consuming her offspring after it has died. That was the case with this new observation as well. In this instance, the researchers documented an adult female drill—a type of monkey that looks similar to a mandrill. They are native to the rainforests of Nigeria, Cameroon and parts of Equatorial Guinea and are considered to be endangered. They are also omnivorous.

The instance of cannibalism was observed and recorded by staff at the park. They sent what they found to the research team for analysis.

The focus of this effort, a young female, gave birth to a male at the Dvůr Králové safari park in the Czech Republic. Eight days later, for unknown reasons, the infant died. Following the death, the mother, named Kumasi, carried the dead infant around in the enclosure. Other monkeys in the troop came by to inspect the dead infant and to communicate with Kumasi.

Kumasi carried the dead infant for two days. The first day, she carried it as if it were still alive, stopping periodically to peer into its eyes to see if she could find a reaction. Finding none, she would roam around the pen carrying the corpse with her. On the second day, Kumasi appeared to have come to grips with the reality of the death of her infant. She carried it with less care and then at one point, she picked a spot in the pen, sat down, and began tearing flesh from its body which she placed into her mouth. She seemed bent on consuming the entire corpse, but park staff intervened, entering the pen and collected the remains.

The researchers suggest that the reason the monkey ate her dead infant was to recover more rapidly from the rigors of giving birth, thereby increasing her potential for mating and reproducing again as soon as possible.

When a creature's stress levels decrease because of the presence of a companion, it is known as social buffering. In highly social animals, such as mammals and birds, this phenomenon is well studied. Now, researchers have examined social buffering in rattlesnakes and found that the presence of a second snake significantly reduced rattlesnakes' change in heart rates after they experienced disturbance. It is the first evidence of social buffering in reptiles.

When animals suffer from acute or , they produce more hormones causing shifts in the , and behavior. Some animals, if they are in the presence of a conspecific, can modulate their response to buffer . This is known as social buffering.

There is some research suggesting that snakes can exhibit complex social behavior. Nevertheless, social buffering in reptiles, as well as in other asocial organisms and solitary foragers, hasn't been studied extensively. Now, researchers in the U.S. have examined if  inhabiting Southern California use social buffering to alleviate acute stress.

"We showed that when two snakes were together and experienced a stressful situation, they could buffer each other's , much like what happens to humans when they endure a stressful event together," said Chelsea Martin, a Ph.D. student at Loma Linda University and first author of a new Frontiers in Ethology study. "This dampening of the stress response has not been reported previously in any reptile species."

Snakes that rattle buffer

When exposed to stress, the presence of a snake companion reduced the change in heart rate of snakes significantly. Because the researchers worked with wild-caught rattlesnakes, they could show that social buffering likely exists in nature and can persist in captivity.

"Our test snakes came from populations that overwinter individually and communally. We found no differences in snake populations who did or didn't overwinter in groups," Martin explained. "We also did not observe a difference in social buffering between the sexes."

Montane rattlesnakes hibernate communally, which could have been an indicator of stronger social networks than in lowland rattlesnakes, which usually overwinter alone. It is also known that female rattlesnakes aggregate during pregnancy and remain with newborn offspring. Testing for these variables helped the researchers establish that proclivity to buffer was equally pronounced in both populations as well as female and male snakes.

Snakes in a bucket

For their study, the researchers assessed social buffering in 25 wild-caught southern Pacific rattlesnakes in three scenarios: when the snakes were alone, in the presence of a rope that served as inanimate control object, and while the snakes were in the presence of a same-sex companion.

Measuring rattlesnakes' heart rates should be a reliable indicator of  levels and social buffering. To obtain data, the researchers outfitted the snakes with electrodes near their hearts and attached the sensors to a heart rate monitor. They then placed the snakes in a bucket—a dark, enclosed testing environment.

After an adjustment period of 20 minutes, the snakes were artificially disturbed. Then Martin and the research team measured the snakes' heart rate increase from baseline, the time it took for their heart rate to return to normal, and the time they spent rattling.

An image boost for rattlesnakes

"Our results provide insights into social behavior patterns of snakes," said Martin. "But it might also improve rattlesnakes' image. In the public eye they are often maligned. Our findings could help to change that," she added.

The scientists also pointed to some limitations they worked with. During the experiment's duration, the  pairs were kept in very confined spaces. Accordingly, they did not examine whether a stress buffering response occurs when snakes are close, but not in physical contact with each other. Another unknown variable, which the researchers hope to test in the future, is if familiarity between two snakes impacts their social buffering response.

Study says drinking water from nearly half of US faucets contains potentially harmful chemicals

Drinking water from nearly half of U.S. faucets likely contains "forever chemicals" that may cause cancer and other health problems, according to a government study released Wednesday.

The synthetic compounds known collectively as PFAS are contaminating drinking water to varying extents in  and small towns—and in private wells and public systems, the U.S. Geological Survey said.

Researchers described the study as the first nationwide effort to test for PFAS in  from private sources in addition to regulated ones. It builds on previous scientific findings that the chemicals are widespread, showing up in  as diverse as nonstick pans, food packaging and water-resistant clothing and making their way into .

Because the USGS is a scientific research agency, the report makes no policy recommendations. But the information "can be used to evaluate risk of exposure and inform decisions about whether or not you want to treat your drinking water, get it tested or get more information from your state" about the situation locally, said lead author Kelly Smalling, a research hydrologist.

The U.S. Environmental Protection Agency in March proposed the first federal drinking water limits on six forms of PFAS, or per- and polyfluorinated substances, which remain in the human body for years and don't degrade in the environment. A final decision is expected later this year or in 2024.

But the government hasn't prohibited companies using the chemicals from dumping them into public wastewater systems, said Scott Faber, a senior vice president of the Environmental Working Group, an advocacy organization.

"We should be treating this problem where it begins, instead of putting up a stoplight after the accident," he said. "We should be requiring polluters to treat their own wastes."

Studies of lab animals have found potential links between PFAS chemicals and some cancers, including kidney and testicular, plus issues such as high blood pressure and low birth weight.

Federal and state programs typically measure exposure to pollutants such as PFAS at water treatment plants or groundwater wells that supply them, Smalling said. In contrast, the USGS report was based on samples from taps in 716 locations, including 447 that rely on public supplies and 269 using private wells.

The samples were taken between 2016 and 2021 in a range of locations—mostly residences but also a few schools and offices. They included protected lands such as national parks; residential and  with no identified PFAS sources; and urban centers with industry or waste sites known to generate PFAS.

Most taps were sampled just once. Three were sampled multiple times over a three-month period, with results changing little, Smalling said.

Scientists tested for 32 PFAS compounds—most of the ones detectable through available methods. Thousands of others are believed to exist but can't be spotted with current technology, Smalling said.

The types found most often were PFBS, PFHxS and PFOA. Also making frequent appearances was PFOS, one of the most common nationwide.

Positive samples contained as many as nine varieties, although most were closer to two. The median concentration was around seven parts per trillion for all 32 PFAS types, although for PFOA and PFOS it was about four parts per trillion—the limit EPA has proposed for those two compounds.

The heaviest exposures were in cities and near potential sources of the compounds, particularly in the Eastern Seaboard; Great Lakes and Great Plains urban centers; and Central and Southern California. Many of the tests, mostly in rural areas, found no PFAS.

Based on the data, researchers estimated that at least one form of PFAS could be found in about 45% of tap water samples nationwide.

The study underscores that private well users should have their  tested for PFAS and consider installing filters, said Faber of the Environmental Working Group. Filters containing activated carbon or reverse osmosis membranes can remove the compounds.

The USGS study is "further evidence that PFAS is incredibly pervasive and folks who rely on private wells are particularly vulnerable to the harms caused by these chemicals," Faber said.

The profile of scent compounds from a person’s hand can be used to predict their sex, according to a new study led by Kenneth Furton of Florida International University, publishing July 5 in the open-access journal PLOS ONE.

In criminal investigations, dogs have long been used to reliably identify and track people based on their odor. But while human scent evidence from the field is well established, researchers have made little progress in analyzing human scent profiles in the lab.

In the new study, researchers used an analysis technique called mass spectrometry to analyze the volatile scent compounds present on the palms of 60 individuals – half male and half female. After identifying the compounds in each sample, the team performed a statistical analysis to see if they could determine the individual’s sex based on their profile of scents. The analysis successfully predicted a person’s sex with a 96.67% accuracy rate.

Robberies, assaults and rape are all crimes that are often executed with a perpetrator’s hands, and thus have the potential to leave behind valuable trace evidence at a crime scene. The new study shows that it is possible to predict a person’s sex based on hand scents, and existing human odor research indicates scent compounds can also reveal a person’s age and racial or ethnic group. With further validation, the chemical and statistical analyses presented in this paper could be used to uncover many details about a potential perpetrator solely through their hand scent profiles.

The authors add: “This approach to analyzing hand odor volatiles can be applied when other discriminatory evidence such as DNA is lacking and allow for differentiation or class characterization such as sex, race and age.”

When asked to draw their local wildlife, 401 UK schoolchildren aged 7 to 11 most commonly drew mammals and birds, while amphibians and reptiles appeared in the fewest drawings, suggesting imbalances in children’s ecological awareness. Kate Howlett and Edgar Turner of the University of Cambridge, UK, present these findings in the open-access journal PLOS ONE on July 5, 2023.

Prior research has shown that, overall, European and North American children’s access to green space has declined in recent decades, and they are becoming increasingly disconnected from nature. Access to greenspace is associated with better cognitive function for children, and disconnection with nature may reduce children’s future support for conservation.

To deepen understanding of children’s connection with nature, Howlett and Turner asked 401 children aged 7 to 11 from 12 schools in England to draw and label the animals living in their gardens and in parks near their homes. The researchers then analyzed the different types and specificity of the wildlife depicted.

The analysis showed that mammals—such as squirrels, cats, and hedgehogs—appeared in 80.5 percent of the drawings, more often than any other type of animal. Birds were the second most common type, found in 68.6 percent of drawings. Insects and other invertebrates were less common, and amphibians and reptiles were least common, appearing in 15.7 percent of the drawings. Although the children were not asked to draw plants, plants appeared in 91.3 percent of the drawings.

The children were most specific when drawing mammals and birds, with most of these animals being an identifiable species. Among animals, insects, reptiles, amphibians and other invertebrates were less often identifiable to species. Among plants, trees and crops—such as strawberries, potatoes, and carrots—were most identifiable.

On the basis of these findings, the researchers suggest that children’s ecological awareness is focused on mammals and birds. Further analysis suggested that ecological awareness may be tied more strongly to at-home or cultural influences, rather than attending a state- versus privately funded school.

The researchers call for broad efforts to boost ecological awareness through adjusting national school curricula and expanding green spaces at schools.

The authors add: “Children’s perceptions of the local wildlife with which they share their gardens and local parks are skewed towards mammals and birds. Not only do children draw mammals and birds more often than they draw invertebrates, amphibians or reptiles, but they are also able to identify them more precisely than they are the smaller, less charismatic groups. While this is perhaps unsurprising, given that it mirrors similar slants in wider media and culture, biases in children’s perceptions of the natural world hint at a wider problem of nature disconnect and attrition of ecological knowledge, and suggest we need to readdress these biases as a matter of urgency.”
