The hidden carbon cost of reality TV shows like The Traitors

Source: The Conversation – UK – By Jack Shelbourn, Senior Lecturer and Director of Photography, University of Lincoln

Millions of us unwind with reality television. It’s comforting, social and, when the format is good, brilliantly engineered drama. But there’s an invisible carbon cost to all that escapism.

Plenty of attention has been paid to the carbon footprint of big Hollywood productions, but less so to unscripted TV. Yet the key emitters are similar: travel, energy and materials.

The British Film Institute’s Screen New Deal, a landmark 2020 report on the environmental impact of UK Film Production, found that an average tent-pole show (a high-budget feature that is expected to be a success) produces around 2,840 tonnes of carbon dioxide equivalent (CO₂e) during production. That’s roughly the annual absorption of more than 3,000 acres of forest, and the equivalent of 11 one-way trips to the Moon.

In television, the pattern persists. Bafta’s latest industry data, drawn from thousands of UK and international TV productions, reports about 174,000 tonnes of CO₂e were generated from productions completed in 2024. Travel and transport made up around 65% of that footprint, and energy a further 21%.

These productions burned some 3 million litres of generator fuel last year, while only 2% of recorded car journeys were electric. Flights alone contributed about 30% of total industry emissions in 2024.

And these numbers cover only the “making of” column. They don’t include the downstream emissions from distribution data centres and the devices we watch on. Nor do they capture what economists call “induced demand” – when screen stories inspire consumption.

The Traitors and the carbon of desire

Take The Traitors. The BBC show’s core is psychological: people at a table trying to read each other. Yet the look and feel are scaffolded by a language of luxury adventure – convoys of vehicles, helicopter shots and speedboats.

When a prestige reality show glamorises high-carbon lifestyles, it doesn’t just burn emissions during production – it normalises this behaviour. Research on ITV’s dating show Love Island has shown how a programme’s aesthetic and product associations can directly spike audience consumption patterns, from fast fashion to cosmetic procedures.

Bafta’s climate content analysis also highlights how screen narratives can legitimise environmentally harmful choices through repetition and tone. This fits within a wider media pattern where screen culture reinforces certain identities, aspirations and ways of living. When the “aspirational” look is carbon-heavy, the influence is felt far beyond the set.

In the Traitors, contestants are driven around the Scottish Highlands in vintage Land Rover Defenders, complete with custom number plates. The car-selling website Autotrader saw 90,000 searches for this model in January 2024 when The Traitors was on air – a spike seen again in 2025 during Celebrity Traitors.

Under Bafta’s sustainability framework, most UK broadcasters now require a carbon action plan before filming begins, and must measure their full carbon impact after completing each show. Compliance is encouraged through certifications and is increasingly written into broadcaster contracts.

That’s progress – but the Bafta data shows stubborn problems remain: planes, road fleets, diesel power and material waste.

Practical fixes exist – trains instead of short-haul flights, economy class where flying is unavoidable, electric vehicles instead of diesel, plant-forward catering and circular set design.

Cutting one in four flights and switching a third of road journeys to electric vehicles would, on Bafta’s modelling, significantly reduce the sector’s footprint. Replacing diesel with hydrotreated vegetable oil and prioritising hybrids could drive further reductions.

Changing what ‘exciting’ looks like

The most powerful lever isn’t always new technology, it’s commissioning – choosing formats that don’t need high-carbon logistics to feel exciting. We don’t need to cancel fantasy to cut emissions – we need to change what “exciting” looks like. Three shifts would get us there fast:

1. Rebalance the grammar of spectacle.

Reality TV doesn’t become dull when you strip out the expensive convoy. The Traitors proves the opposite. The most gripping moments in the show happen around the table, not behind the wheel. Drama doesn’t need horsepower to hold our attention.

2. Localise by default.

The biggest savings come when productions avoid flights altogether. Productions that hire local crews and cast and choose accessible locations can slash travel emissions while investing in communities. The BFI Sustainable Screen: Black Samphire report shows how integrating local action, from beach cleans to a “climate positive clause” in production, can turn community engagement into both a sustainability and legacy strategy.

3. Design low-energy craft into the look.

Cameras and lighting can now deliver strong results with smaller, fewer fixtures and more reflective control, cutting power and transport without harming picture quality. In my teaching and research, I’ve demonstrated that replacing all the lights and clutter on a film set with a single light source, which is then bounced around the set to create the illusion of many lights, can replace multi-head rigs for many scenes, slashing energy use while improving speed and safety.

Productions that rely less on diesel and long-haul logistics are cheaper to insure, easier to schedule, quieter on location and more resilient to fuel-price shocks and grid constraints.

Audiences aren’t powerless. I love The Traitors – I’ve watched all the UK seasons and some international ones too. It’s a great way to get through the post-Christmas blues. But it’s time we asked broadcasters to publish their carbon action plans in plain English – and for us to celebrate productions that make their low-carbon choices visible through smart logistics and elegant craft.

We’ve learned to recognise intimacy coordinators and accessibility credits – sustainability leads should be there too.

Reality TV isn’t the villain of the climate story. But it is a powerful amplifier of taste. If commissioners prioritise formats that deliver drama without flights, convoys and diesel, and crews embrace low-energy craft, the sector can cut much of its footprint – while telling even better stories.


The climate crisis has a communications problem. How do we tell stories that move people – not just to fear the future, but to imagine and build a better one? This article is part of Climate Storytelling, a series exploring how arts and science can join forces to spark understanding, hope and action.

I Deliver Parcels in Beijing by Hu Anyan: an unforgettable look at gig-economy hardship

Source: The Conversation – UK – By Bran Nicol, Professor of English, University of Surrey

From HBO drama Succession to Netflix reality show Selling Sunset, TV depictions of work tend to treat it as a vehicle for social betterment rather than a means to survival. The Chinese writer Hu Anyan’s arresting memoir, I Deliver Parcels in Beijing, just published in an English translation, provides an alternative perspective.

The book began life as a lockdown blog post about its author’s experiences in a logistics warehouse. When it went viral, he reshaped it into a book about his time working as a courier and in a range of other low-paid positions, from waiter to gas station attendant.

It has now sold almost 2 million copies in China, and nearly 20 countries have translation rights. The 46-year-old Hu was dubbed “one of China’s most remarkable new literary talents” by the Financial Times.

Despite documenting hardship and frustration, I Deliver Parcels in Beijing is narrated in an intimate and witty style – for which English translator Jack Hargreaves deserves great credit.

It’s an unforgettable portrayal of the gruelling realities of work in the gig economy. The book covers the dire effects on sleep and health, punishing shifts without breaks, stressed-out bosses and rivalries between workers. It’s packed with engaging stories about the people Hu works with and delivers to.

Though the central theme is about work in general, the book’s title shrewdly highlights one job which now occupies a particularly prominent position both socially and culturally. During the pandemic online delivery driving was termed a new “emergency service” – a function which had been prophetically mythologised in the 2019 action-adventure video game, Death Stranding, which casts the courier as post-apocalyptic saviour.

Souleymane’s Story: the quietly devastating tale of an immigrant worker’s struggles in Paris


Earlier this year Stephen Starring Grant’s touching memoir Mailman showed that the true purpose of being a letter carrier in rural Appalachia was to provide a lifeline for the isolated and lonely.

Autobiographical writing such as Grant’s – and now Hu’s – shows that the narrow perspective of one person’s experience can also illuminate something much broader. By presenting his life as a patchwork of all the jobs he has had, Hu provides a powerful insight into a much larger system – or rather into three vast systems which have profoundly shaped contemporary existence.

There is the enormous, largely hidden, network of logistics and “platform capitalism” – the system which uses digital platforms to connect different users in the economic chain – upon which we all increasingly depend. I Deliver Parcels in Beijing allows us to peek inside this world, and learn how it operates – from the bureaucratic labyrinth of being onboarded as a contractor to the frustrations of having to cover the cost of lost parcels, or to wait while customers try on clothes they’ve ordered on the spot.

Then there are the glimpses of everyday life in contemporary China, a driving force behind much of the world’s economy but still mysterious to those in the west. Hu’s book shines a light on the predicament of “internal migrants” – the members of a 300-million strong workforce uprooted from their rural hometowns to find work in cities, where their undocumented status forbids them access to social services.

But it also provides rich insight into all sorts of distinctive aspects of Chinese life, from social and culinary customs to a village in which everyone still shares the same surname.

But enveloping all this is the irrepressible system of late-stage capitalism – which China is able to inhabit so formidably through its unique blend of market economy and state-owned and private business. For those in the west, to read I Deliver Parcels in Beijing is to enter a fascinating parallel universe.

There is no Amazon but the vast Alibaba ecosystem of online retail, WeChat instead of Facebook, and Goade Maps rather than Google Maps. But in its charming, understated way, the book is a vivid account of the process Marxists term “alienation”.

Work in the gig economy is a means to survive rather than a form of self-expression. Its workers do not control their labour nor own its products, and can become dehumanised.

Though too modest and self-deprecating to be a memoir with a strong political message, I Deliver Parcels in Beijing is nevertheless a quietly critical story of how it feels to be stuck in this system.

After a few weeks as a delivery driver Hu begins to notice his personality changing. He finds himself shouting at an annoying customer, and feeling nothing when he makes an old man wait for his delivery on the sidewalk for nearly three hours.

It is reasonable to assume, from his memoir’s inspiring, open-hearted humanity, that this does not represent the person Hu really is. As he writes, however: “There is a reason that deep-sea fish are blind, and animals in the desert tolerant of thirst – a big part of who I am is determined by my environment and not my nature.”

Choking during sex is common among young adults, but the risks are poorly understood

Source: The Conversation – UK – By Christopher Saville, Clinical Senior Lecturer, School of Psychology and Sport Science, Bangor University

Choking during sex has moved from the margins to the mainstream for many young adults, but the risks have not changed. New research shows how common the practice has become, and how confused many people are about what makes it dangerous.

A survey commissioned by the Institute for Addressing Strangulation (IfAS) has found that more than one-third of people aged 18 to 34 have been choked or strangled at least once during consensual sex. IfAS is a UK-based organisation that aims to reduce harms from strangulation in domestic abuse, sexual contexts and forensic settings – environments where injuries are examined for legal, evidential or investigative purposes.

The survey findings suggest that pornography featuring choking is helping to normalise strangulation during sex among young adults. The report was published as the UK government prepares to ban such content in the upcoming crime and policing bill.

While many participants reported positive experiences, others described deeply negative experiences, and just over one-quarter said they had been choked without agreeing to it first. This raises particular concern because choking during sex sometimes intersects with domestic abuse and non-fatal strangulation is a known predictor of serious harm in intimate partner violence.

When a behaviour that is well documented in coercive and violent relationships becomes normalised in consensual settings, the boundaries can blur. Young people may struggle to distinguish experimentation from harm and may feel pressured to accept acts they do not want. The survey’s accounts of distress and lack of consent highlight how these boundaries can erode.

One of the most revealing parts of the survey explored how people think about danger. Almost three-quarters of respondents described choking during sex as either “very dangerous” or “somewhat dangerous”. However, when asked whether it is possible to strangle someone safely during sex, opinions were divided. Twenty-nine percent believed it is possible, 39% believed it is not and 32% were unsure.

Participants also gave a wide range of answers about how a person might try to make this safer. One important theme was that participants were divided about whether it is more important to avoid pressing on the airway or on the blood vessels in the neck.

This confusion matters because the body responds very differently to these types of pressure. Strangulation denies the brain oxygen and this can happen in two ways.

One involves blocking the airway, which makes breathing difficult or impossible. The other involves interrupting the flow of blood to and from the brain, by blocking blood vessels on the side of the neck.

Some people use the word choking for the first and strangulation for the second, but these terms are often used in confusing ways.

A key difference is how quickly these two types of strangulation affect the brain. Blocking breathing can take around one minute to cause unconsciousness. Blocking blood flow can cause unconsciousness in as little as five to ten seconds.

Another difference is that restricted breathing feels uncomfortable and obvious, while restricted blood flow can be hard to recognise until it is too late. It is not intuitive to people that they can be strangled while still being able to breathe.

Strangulation’s rapid effects happen because the brain depends on a constant supply of oxygen. If oxygen is cut off, the brain can suffer damage very quickly. Some areas such as the hippocampus, which plays a central role in memory, are particularly vulnerable.

As oxygen levels fall, the brain tries to protect itself by reducing its own use of oxygen, which causes unconsciousness. If oxygen is not restored quickly, brain cells begin to die.

Strangulation can also harm the body in other ways. Sexual choking can cause a range of physical and psychological injuries and, in extreme cases, can be fatal. During or after choking a person may experience trouble breathing, pain or difficulty swallowing, loss of bladder or bowel control, memory problems or psychological trauma.

In rare cases, choking during sex can trigger a stroke. This can happen if a blood vessel is damaged and bleeds, or if blood pools behind a blockage and forms a clot that later travels to a smaller vessel.

What can be done?

Public health has two broad approaches to risky behaviour. The first is prohibition, which creates legal or practical barriers to prevent dangerous acts.

The UK government’s plan to ban pornography that shows choking is one example. However, sexual practices take place in private settings and cannot be monitored or restricted in the same way as access to pornography, which limits the reach of prohibition.

The second approach is harm reduction. It accepts that people may continue a behaviour even if discouraged and aims to help them reduce the risks. This approach is complicated in the case of sexual choking, because misinformation is widespread and many online communities promote inaccurate ideas about “safe” practice.

Both approaches attract debate. Prohibition is sometimes criticised as intrusive or unrealistic, and harm reduction as condoning dangerous or immoral behaviours. But they do not have to work against each other. They can operate together by reducing the likelihood of a behaviour while equipping people with accurate information about risk.

The IfAS survey shows that many young people misunderstand what makes strangulation dangerous – and this gap in knowledge could have life-threatening consequences. Education that explains how strangulation affects the body could help reduce harm by giving people a clearer sense of the risks involved.

Accurate information would also support wider public health efforts by helping people recognise why certain sexual practices carry significant danger, and why legal and clinical responses are being developed to address them.

Just follow orders or obey the law? What US troops told us about refusing illegal commands

Source: The Conversation – USA – By Charli Carpenter, Professor of Political Science, UMass Amherst

There are certain situations in which the military should not fall in line. Bo Zaunders/Corbis Documentary via Getty Images

As the Trump administration carries out what many observers say are illegal military strikes against vessels in the Caribbean allegedly smuggling drugs, six Democratic members of Congress issued a video on Nov. 18, 2025, telling the military “You can refuse illegal orders” and “You must refuse illegal orders.”

The lawmakers have all served either in the military or the intelligence community. Their message sparked a furious response on social media from President Donald Trump, who called the legislators’ action “seditious behavior, punishable by death.”

One of the lawmakers, Sen. Elissa Slotkin, told The New York Times that she had heard from troops currently serving that they were worried about their own liability in actions such as the ones in the Caribbean.

This is not the first time Trump has put members of the military in situations whose legality has been questioned. But a large percentage of service members understand their duty to follow the law in such a difficult moment.

We are scholars of international relations and international law. We conducted survey research at the University of Massachusetts Amherst’s Human Security Lab and discovered that many service members do understand the distinction between legal and illegal orders, the duty to disobey certain orders, and when they should do so.

The ethical dilemma

With his Aug. 11, 2025, announcement that he was sending the National Guard – along with federal law enforcement – into Washington, D.C. to fight crime, Trump edged U.S. troops closer to the kind of military-civilian confrontations that can cross ethical and legal lines.

Indeed, since Trump returned to office, many of his actions have alarmed international human rights observers. His administration has deported immigrants without due process, held detainees in inhumane conditions, threatened the forcible removal of Palestinians from the Gaza Strip and deployed both the National Guard and federal military troops to Los Angeles, Portland, Oregon, Chicago and other cities to quell largely peaceful protests or enforce immigration laws.

When a sitting commander in chief authorizes acts like these, which many assert are clear violations of the law, men and women in uniform face an ethical dilemma: How should they respond to an order they believe is illegal?

The question may already be affecting troop morale. “The moral injuries of this operation, I think, will be enduring,” a National Guard member who had been deployed to quell public unrest over immigration arrests in Los Angeles told The New York Times. “This is not what the military of our country was designed to do, at all.”

Troops who are ordered to do something illegal are put in a bind – so much so that some argue that troops themselves are harmed when given such orders. They are not trained in legal nuances, and they are conditioned to obey. Yet if they obey “manifestly unlawful” orders, they can be prosecuted. Some analysts fear that U.S. troops are ill-equipped to recognize this threshold.

Compelled to disobey

U.S. service members take an oath to uphold the Constitution. In addition, under Article 92 of the Uniform Code of Military Justice and the U.S. Manual for Courts-Martial, service members must obey lawful orders and disobey unlawful orders. Unlawful orders are those that clearly violate the U.S. Constitution, international human rights standards or the Geneva Conventions.

Service members who follow an illegal order can be held liable and court-martialed or subject to prosecution by international tribunals. Following orders from a superior is no defense.

Our poll, fielded between June 13 and June 30, 2025, shows that service members understand these rules. Of the 818 active-duty troops we surveyed, just 9% stated that they would “obey any order.” Only 9% “didn’t know,” and only 2% had “no comment.”

When asked to describe unlawful orders in their own words, about 25% of respondents wrote about their duty to disobey orders that were “obviously wrong,” “obviously criminal” or “obviously unconstitutional.”

Another 8% spoke of immoral orders. One respondent wrote that “orders that clearly break international law, such as targeting non-combatants, are not just illegal — they’re immoral. As military personnel, we have a duty to uphold the law and refuse commands that betray that duty.”

Just over 40% of respondents listed specific examples of orders they would feel compelled to disobey.

The most common unprompted response, cited by 26% of those surveyed, was “harming civilians,” while another 15% of respondents gave a variety of other examples of violations of duty and law, such as “torturing prisoners” and “harming U.S. troops.”

One wrote that “an order would be obviously unlawful if it involved harming civilians, using torture, targeting people based on identity, or punishing others without legal process.”

Soldiers, not lawyers

But the open-ended answers pointed to another struggle troops face: Some no longer trust U.S. law as useful guidance.

Writing in their own words about how they would know an illegal order when they saw it, more troops emphasized international law as a standard of illegality than emphasized U.S. law.

Others implied that acts that are illegal under international law might become legal in the U.S.

“Trump will issue illegal orders,” wrote one respondent. “The new laws will allow it,” wrote another. A third wrote, “We are not required to obey such laws.”

Several emphasized the U.S. political situation directly in their remarks, stating they’d disobey “oppression or harming U.S. civilians that clearly goes against the Constitution” or an order for “use of the military to carry out deportations.”

Still, the percentage of respondents who said they would disobey specific orders – such as torture – is lower than the percentage of respondents who recognized the responsibility to disobey in general.

This is not surprising: Troops are trained to obey and face numerous social, psychological and institutional pressures to do so. By contrast, most troops receive relatively little training in the laws of war or human rights law.

Political scientists have found, however, that having information on international law affects attitudes about the use of force among the general public. It can also affect decision-making by military personnel.

This finding was also borne out in our survey.

When we explicitly reminded troops that shooting civilians was a violation of international law, their willingness to disobey increased 8 percentage points.

Drawing the line

As my research with another scholar showed in 2020, even thinking about law and morality can make a difference in opposition to certain war crimes.

The preliminary results from our survey led to a similar conclusion. Troops who answered questions on “manifestly unlawful orders” before they were asked questions on specific scenarios were much more likely to say they would refuse those specific illegal orders.

When asked if they would follow an order to drop a nuclear bomb on a civilian city, for example, 69% of troops who received that question first said they would obey the order.

But when the respondents were asked to think about and comment on the duty to disobey unlawful orders before being asked if they would follow the order to bomb, the percentage who would obey the order dropped 13 points to 56%.

While many troops said they might obey questionable orders, the large number who would not is remarkable.

Military culture makes disobedience difficult: Soldiers can be court-martialed for obeying an unlawful order, or for disobeying a lawful one.

Yet between one-third to half of the U.S. troops we surveyed would be willing to disobey if ordered to shoot or starve civilians, torture prisoners or drop a nuclear bomb on a city.

The service members described the methods they would use. Some would confront their superiors directly. Others imagined indirect methods: asking questions, creating diversions, going AWOL, “becoming violently ill.”

Criminologist Eva Whitehead researched actual cases of troop disobedience of illegal orders and found that when some troops disobey – even indirectly – others can more easily find the courage to do the same.

Whitehead’s research showed that those who refuse to follow illegal or immoral orders are most effective when they stand up for their actions openly.

The initial results of our survey – coupled with a recent spike in calls to the GI Rights Hotline – suggest American men and women in uniform don’t want to obey unlawful orders.

Some are standing up loudly. Many are thinking ahead to what they might do if confronted with unlawful orders. And those we surveyed are looking for guidance from the Constitution and international law to determine where they may have to draw that line.

G20 in a changing world: is it still useful? Four scholars weigh in

Source: The Conversation – Africa – By Danny Bradlow, Professor/Senior Research Fellow, Centre for Advancement of Scholarship, University of Pretoria

US president Donald Trump’s address to the annual gathering of the United Nations general assembly in late September 2025 set a new low in international relations. Trump delivered a broadside attack on multilateralism – the effort to solve the world’s problems through collective endeavour – as well as issues that have found common cause among rich and poor countries alike, such as climate change.

So where does this leave the work of organisations such as the G20? The body was set up by the G7 in 1999 in the wake of the Asian financial crisis. The purpose was to create a bigger grouping of countries to help manage the governance of the global economy.

The group now represents about 67% of the global population and about 85% of the global economy. But it’s a strange beast: it is a self-selected group, which raises questions about its legitimacy. And it doesn’t have a permanent secretariat, which makes its work cumbersome.

We asked four leading scholars for their answers. Given the changing global context, is the G20 still useful?

Climate change and inequality are connected – policies need to reflect this

Source: The Conversation – Africa – By Anda David, Senior researcher, Agence Française de Développement (AFD)

An increasingly strong case is being made to bring inequality into discussions about climate change. The logic behind this has been set out by leading international institutions such as the International Labour Organisation, the UN Environmental Programme and the Network for Greening the Financial System.

All have begun to highlight the connection between climate outcomes and inequality. They are stressing that inequality should be viewed as posing systemic and macroeconomic risk. Inequality has been found to undermine democracy, social and political cohesion and economic stability. Inequality also undermines our ability to deal with climate and environmental challenges.

In a recent summary paper we analysed how environmental policies can be designed and implemented with an inequality-reduction lens. We used examples from South Africa, Colombia, Indonesia and Mexico.

As researchers in the research department of the French development agency the AFD, specialising in the analysis of inequality and the social implications of energy and economic transitions, we have seen how climate action can either narrow or deepen existing divides, depending on how policies are designed.

The core of the case we make is that reducing inequality should be a guiding principle in decisions on climate change. There are numerous cases we studied in which it’s clear that countries often simply opt for compensating those who stand to lose from environmental transitions rather than seeking more equitable solutions. This needs to change. But a shift requires focusing on a meaningful reduction of inequality as well as understanding who wins from the transition.

The green transition and the absence of equity

We take the just transition as a starting point as it is increasingly cited as the accepted framework for building sustainable economies. This approach focuses on the social dimension of the ecological and energy transition and highlights the need to secure the livelihood of those negatively affected by the green transition. It highlights an inclusive transition to a low-carbon and sustainable economy, leaving no one behind.

Countries are progressively incorporating just transition principles into their national climate strategies. Examples include South Africa’s 2022 just transition framework and Mexico’s upcoming NDC 3.0. But when it comes to the actual design and implementation of policies, equity is rarely treated as the central concern. This becomes obvious when we look at some of the characteristics of the current green transitions.

Green jobs: The promise often is that these jobs are better, more stable and more sustainable. But the research we coordinated in Colombia with the University of Los Andes shows that these opportunities benefit groups that already have advantages. Examples include university-educated urban men. Women, youth and rural populations remain largely excluded.

Green infrastructures: We looked at who owns green infrastructures, such as solar parks, wind farms, smart grids, and storage systems. We often saw it remained largely in the hands of large private and multinational companies. In South Africa, for instance, the union Numsa has pushed back against a profit-driven renewable energy programme that transferred risks to the state and kept electricity tariffs high. The main beneficiaries of the programme are financial actors and multinational corporations. This is a good illustration of how ownership determines who controls energy as well as who truly gains from the transition.

Environmental protection policies. These include:

  • protected areas – defined spaces with the goal of nature conservation and the preservation of ecosystems

  • biodiversity offsets – intended to compensate for environmental damage caused by development projects.

These policies and plans for environmental protection can generate inequalities as they are often designed top-down. As a result, local communities can lose out.

What needs to shift

Putting inequality reduction at the centre means more than adding a social component to existing programmes.

In Colombia, the findings point to the need for early and targeted public policies to address labour market disparities. Examples include:

  • integrating training in renewable energy, energy efficiency and other sustainability-related skills into technical and vocational training

  • using approaches tailored to local needs and that are sensitive to gender differences.

Another thing that needs to change is the level of support for businesses and particularly small enterprises so that they can contribute to job creation. Most of them operate informally and rely on survivalist strategies. Evidence from South Africa showed that they’re excluded from just energy transition plans.

We also identified areas that need improvement around taxation. A fair climate policy should start with recognising that carbon taxes are not neutral: their burden falls differently across income groups.

In Indonesia, the study we led with our partners using microsimulation found that a €30-per-ton carbon tax would slightly increase costs for lower-middle income households. But when revenues were recycled through targeted cash transfers to low-income and energy-poor households, the policy had positive outcomes.

This example shows that equity depends less on the tax itself than on how its proceeds are used.

Finally, democratising ownership of the energy transition process is key to ensuring that it’s just. Our evidence shows that community and user-owned models can make renewable infrastructure inclusive as well as viable. Examples include community-owned solar installations, worker share ownership schemes and multistakeholder cooperatives.

Inequalities threaten the commitment to existing efforts in the climate domain. Embedding the reduction of inequality into climate action is an opportunity for a meaningful transformation.

The examples we found of best practice as well as the weaknesses in initiatives can help guide policymakers. The needle is moving in discussions on inequality. The suggestion by the G20 Extraordinary Committee of Independent Experts on Global Inequality is a case in point. It has recommended the creation of a global panel to provide guidance to countries on how they can ensure that reducing inequality sits at the heart of their development trajectories.

Mercury pollution in marine mammals is increasing – new study

Source: The Conversation – UK – By Rosie Williams, Postdoctoral Researcher, Toxicology, Institute of Zoology, Zoological Society of London

In 2017, a new global treaty was meant to bring mercury pollution under control. But three decades of data from UK harbour porpoises show mercury is still increasing, and is linked to a higher risk of dying from infectious disease.

When the Minamata convention came into force eight years ago, it was hailed as a turning point. The global treaty on mercury commits countries to reducing mercury from coal-fired power plants, industry and products, like batteries and dental fillings.

Yet mercury levels are still rising in many parts of the ocean. Human activities such as the burning of fossil fuels have already tripled mercury in shallower ocean waters (less than 1,000m in depth) since the industrial revolution. Warmer seas and shifting food webs are exacerbating the problem by increasing the rate of accumulation in the marine food chain.

In our new study, my colleagues and I analysed liver samples from 738 harbour porpoises that stranded along UK coastlines between 1990 and 2021. We found mercury levels increased over time and animals with higher levels are more likely to die from infectious disease.

Harbour porpoises are sentinels of ocean health because they are long lived (often for more than 20 years) and high up the food chain. This makes them more vulnerable to certain pollutants. The contaminants that build up in them are a warning for the marine ecosystem – and for us.

We measured trace elements as part of the UK’s strandings programmes in England, Wales and Scotland – the Cetacean Strandings Investigation Programme (CSIP) and the Scottish Marine Animal Stranding Scheme (SMASS). Stranded animals die from a range of causes, including bycatch in fishing gear and disease. When found washed up, a subset are sent to our London laboratory for post-mortem examination to help us better understand the population and the threats they face.

We sampled each animal to measure eight trace elements, including mercury, in their liver, which plays a critical role in the metabolism, detoxification and accumulation and tends to be where concentrations are highest. We analysed how concentrations changed over time, how they varied geographically around the UK, and whether levels were related to cause of death.

Over the last 30 years, mercury concentrations in porpoise livers rose by about 1% per year. By 2021, the average mercury concentration was almost double that of early 1990s. A worrying minority (about one in ten animals in the last decade) had mercury levels where serious health effects are expected.

In contrast, lead, cadmium, chromium and nickel declined, reflecting past bans and tighter controls on these pollutants (such as the ban on lead petrol).

We then investigated whether metal burdens were linked to health. Comparing porpoises that died of infectious disease with those that died of trauma, such as bycatch in fishing gear, we found that animals with higher burdens of mercury had a significantly greater risk of dying from infectious disease.

In parallel, we saw a steady increase in the proportion of porpoises dying from infectious disease and a corresponding decline in deaths from trauma. That doesn’t prove mercury is the sole cause. Many factors, including nutritional stress and other pollutants like industrial chemicals called polychlorinated biphenyls (PCBs), also affect immune function. But our study strongly suggests that mercury is part of the problem.

Why mercury is rising

Large amounts of mercury from past coal burning, industry and mining are already present in the oceans. Much of it sits in deeper waters acting as a source supplying shallower water and can take decades or centuries to be removed. This may explain why declines aren’t evident.

Climate change and overfishing are also disrupting marine food chains. This affects the formation and bioaccumulation (build up in tissues) of methylmercury (the toxic organic form of mercury), increasing levels in the fish that porpoise prey on. And global emissions have not stopped: coal power, cement production and sources such as dental amalgam still release mercury to the environment.

The five most poisonous substances: from polonium to mercury


Our findings highlight that mercury ins’t just a historical problem. It is a current, growing pressure on marine mammals that face multiple other stresses: bycatch, noise pollution, habitat degradation, climate-driven prey shifts and exposure to forever chemicals.

Because mammals share many aspects of physiology and immune function, the trends in porpoises offer a warning for human health too. If top predators in UK coastal waters are becoming more contaminated, the same processes may be affecting some of the fish and shellfish we eat.

Harbour porpoises are small, shy and easily overlooked. But their tissues are quietly recording the story of our chemical footprint in the sea. Right now, that story is telling us something uncomfortable: even after a global treaty, mercury pollution is still rising, and it is affecting the health of marine wildlife.

Mercury and climate change are two sides of the same problem: burning fewer fossil fuels cuts CO₂ and mercury, while missing climate targets risks driving more methylmercury into marine food webs. A safer ocean for porpoises and for people can be achieved by phasing out coal more quickly, reducing industrial emissions and moving away from mercury-containing products wherever safer alternatives exist.

The outlook for marine mammals can also be improved by addressing other human threats such as bycatch, underwater noise and other pollutants. None of this works without long-term monitoring, so continued investment in programmes, like the UK strandings network that underpinned our study, is essential to assess progress.

$2B Counter-Strike 2 crash exposes a legal black hole: Your digital investments aren’t really yours

Source: The Conversation – USA (2) – By João Marinotti, Associate Professor of Law, Indiana University

In late October 2025, as much as US$2 billion vanished from a digital marketplace. This wasn’t a hack or a bubble bursting. It happened because one company, Valve, changed the rules for its video game Counter-Strike 2, a popular first-person shooter with a global player base of nearly 30 million monthly users.

For years, its players have bought, sold and traded digital cosmetic items, known as “skins.” Some rare items, particularly knives and gloves, commanded high prices in real-world money – up to $1.5 million – leading some gamers to treat the market like an investment portfolio. As a result, many investment-style analytics websites charge monthly fees for financial insight, trends and transaction data from this digital marketplace.

In one fell swoop, Valve unilaterally changed the game. It expanded the “trade up contract,” allowing players to exchange – or “trade up” – a number of their common assets into knives or gloves.

By flipping this switch, Valve instantly upended digital scarcity. The market was flooded with new supply, and the value of existing high-end items collapsed. Prices plummeted, initially erasing half the market’s total value, which exceeded $6 billion before the recent crash. Although a partial recovery brought the net loss to roughly 25%, significant volatility continues, leaving investors unsure whether the bottom has truly fallen out.

Many of those who saw their digital fortunes evaporate immediately wondered whether there was anything they could do to get their money back. Speaking as a law professor and a gamer myself, the answer isn’t what they want to hear: no. In fact, the existing legal structure largely protects Valve’s ability to engage in this sort of digital market manipulation. Players and investors were simply out of luck.

The Counter-Strike 2 crash reveals a troubling reality that extends far beyond video games: Corporations have built exchange-scale investment markets governed primarily by private terms-of-service agreements, rather than the robust set of public regulations that oversee traditional financial and consumer markets. These digital economies occupy a legal blind spot, lacking the fundamental guardrails of property rights, meaningful consumer protection or even securities regulation.

Buyer’s guides like this one have cropped up on YouTube.

Your digital ‘property’ isn’t really yours

If you spend real money on a digital item, it may feel like you should own it. Legally, you don’t.

The digital economy is built on a crucial distinction between ownership and licensing. When users sign up for Steam, Valve’s platform, they agree to the Steam subscriber agreement. Buried in that contract is a critical piece of legalese stating that all digital assets and services provided by Valve, including the Counter-Strike 2 skins, are merely “licensed, not sold.” The license granted to users “confers no title or ownership” at all. This isn’t meaningless corporate jargon; it’s a legal standard routinely affirmed by U.S. courts.

The legal implication is clear: Because players only license their skins, they have no property rights over them. When Valve changed the game’s mechanics in a way that collapsed the items’ market value, it didn’t steal, damage or destroy anyone’s “property.” In the eyes of the law, Valve simply altered the conditions of a license, something that its terms-of-service agreement allows it to do unilaterally, at any time, for any reason.

Consumer protection laws don’t apply

While the Counter-Strike 2 crash may seem like a violation of consumer rights, current laws are ill-equipped to handle this type of corporate behavior.

Lawmakers have begun addressing concerns about digital goods, primarily focusing on instances where purchased movies or games disappear entirely from user libraries. For example, California recently enacted AB 2426. This law requires transparency, prohibiting terms like “buy” or “purchase” unless the consumer confirms that they understand they will receive only a revocable license.

As commendable as this law is, it protects only against confusion and loss of access, not loss of market value when platforms rebalance virtual economies. Valve can comply with consumer transparency laws and still adjust the supply of digital items, rendering them valueless overnight. Ultimately, current consumer protection laws are designed to ensure users know what they are licensing. They do not, however, create ownership interests or protect the speculative value of those digital items.

Game items are treated like unregulated stocks

Perhaps the most significant legal vacuum is the absence of financial regulation. The Counter-Strike 2 economy, a multibillion-dollar ecosystem with dedicated investors and third-party cash markets, looks and behaves like a traditional financial market. Yet, it remains outside the purview of any financial regulator, such as the U.S. Securities and Exchange Commission.

Under U.S. law, the primary standard for determining whether an asset should be governed as a security is the Howey test. According to this Supreme Court precedent, an asset is a security if it meets four criteria. Securities involve an “investment of money” in a “common enterprise” with a reasonable expectation of “profits” derived from the “efforts of others.”

Counter-Strike 2 skins arguably meet all of these criteria. Participants invest real money in a common enterprise – Valve’s platform – with an expectation of profit. Crucially, that profit depends on the “efforts of others.” The SEC notes this prong is met when a promoter provides “essential managerial efforts” that affect the enterprise’s success. Valve controls the game’s development, manages the platform and – as the recent update proves – dictates item supply and scarcity.

If a publicly traded company unilaterally changed its rules in a way that predictably tanked the price of its own shares, regulators would immediately investigate for market manipulation. So how can Valve get away with this? Three things cut against the skins’ status as securities.

First is their “consumptive intent” – skins are primarily game cosmetics. Second, there’s no way to convert the skins into dollars within Valve’s own ecosystem. In other words, third-party markets allow users to cash out, but these markets operate outside Valve’s own immediate control. And finally, the Howey test generally governs assets, such as stocks and bonds, that grant investors enforceable rights. Valve’s licensing scheme attempts to circumvent this by ensuring players hold nothing but a revocable license.

In my view, the $2 billion crash is a wake-up call. As digital economies grow in financial significance, society must decide: Will these markets continue to be governed solely by private corporate contracts? Or will they require integration into more robust legal frameworks, such as securities regulation, consumer protection and property law?

From ‘mail-order brides’ to ‘passport bros,’ the international dating industry often sells traditional gender roles

Source: The Conversation – USA (3) – By Julia Meszaros, Associate Professor of Sociology, Texas A&M University-Commerce

For many American men, the draw of the international dating industry is the idea of ‘more traditional’ women. Kurgenc/iStock via Getty Images Plus

Fifteen years ago, when I started studying the international dating industry, few people took the subject seriously. The term “mail-order bride” was treated as a punch line – something outdated, associated with lonely men and poor women who migrated from Eastern Europe, Asia or other places to meet their new husbands in the United States.

But I’ve seen firsthand how ideas about gender, intimacy and global mobility have shifted. In 2025, a man going abroad to look for love might call himself a “passport bro” – and celebrate his lifestyle on TikTok.

This new generation of young men may have rebranded international dating, but they reflect an age-old theme. Social and economic changes shape how people negotiate love and labor across borders, as I explore in my 2025 book, “Economies of Gender.” In a chaotic world, some men and women turn to traditional gender roles as a source of seeming stability – and that often leads them abroad.

Old industry, new look

The term “mail-order bride” dates back to the 19th century, when so-called frontier brides advertised themselves in newspapers to single men in the American West. After the Civil War, when large numbers of men had died on the East Coast, some women saw migrating to the frontier to marry someone sight unseen as a way to secure stability. That narrative still lingers today in Western novels and films.

The modern international matchmaking industry, however, took shape in the 1970s, when catalogs of mostly Filipino women’s photos and addresses were sold to American men. After being pen pals, men would travel to the Philippines to meet and decide whether they wanted to get married. Some scholars consider this a form of human trafficking, but that has been challenged by other scholarship.

These catalogs emerged as more U.S. women were entering the workforce and earning their own money. Some men sought wives abroad who they believed would embody more traditional values – prioritizing domestic work and devoting themselves to men and children.

Over the next few decades, large numbers of stable, well-paying factory jobs disappeared, further challenging some men’s view of themselves as breadwinners.

By 2010, the catalog system had moved online and expanded into a global industry that generated US$2 billion dollars per year. Today, it takes many forms. Most of the industry is online, with email and chat correspondence that charges men but not women. Some agencies provide in-person tours for male clients, and there are higher-end, more personalized matchmaking services as well.

From taboo to televised

What was once stigmatized has become more normalized through reality TV. TLC’s hit series “90 Day Fiance,” which came on air in 2014, has transformed international dating into a lucrative entertainment franchise.

The show and its numerous spin-offs show couples navigating the K-1 visa process, which gives 90 days to marry after a partner enters the country. If the wedding is called off, the foreign fiance or fiancee must return to their country of origin.

Many of the featured couples met randomly, in person. A significant number, however, connected through online dating or language-learning sites. Numerous couples’ storylines highlight family and friends of the American partner who question the girlfriend’s or boyfriend’s motives, accusing them of faking love for financial gain and access to a green card.

Audiences might watch the show for drama or love stories, but the underlying themes mirror what I’ve seen in the field: relationships shaped by economic inequality and migration, with women often exchanging emotional, domestic and sexual labor in return for financial stability.

Rise of the ‘passport bros’

In recent years, the mail-order bride industry has gotten a cultural revamp, with younger and more diverse men who identify as “passport bros.” This crowd is typically younger than men participating in the commercial international dating industry and more likely to identify as men of color.

These men are less likely to pay for formal dating and introduction services. They travel on their own, using free dating apps such as Tinder to meet local women – mostly in Colombia, Brazil and the Dominican Republic.

Passport bros say they travel abroad to meet women who are more traditional than the ones they meet at home. Many of the American men I interviewed between 2010 and 2022 talked about Western women as too focused on career, which challenged their idea of themselves as financial providers.

Similarly, my research in Ukraine, Colombia and the Philippines shows that many men using international dating services are motivated by more than just love or cultural curiosity. They are responding to a changing world in which women’s financial independence has challenged traditional male roles. For some, traveling abroad is a way to reassert control and to find relationships that reaffirm a sense of masculine identity.

In my interviews, American men looking abroad talked about feeling empowered and having choices, while being ignored in the U.S. dating market. Some recognized that their relative wealth is the cause of this. As one man on a romance tour in Ukraine told me in 2012, “I am here to exchange my financial stability for some Ukrainian woman’s youth and beauty, and I am OK with that.”

Appeal of ‘tradition’

Together, many of these daters illustrate the global pattern I’ve seen across my years of fieldwork: anxiety fuels a longing for traditionalism.

What appears to be a return to the past is, in reality, an adaptation to the present. The romance tours, the “90 Day Fiance” phenomenon and the passport bros speak to how people use relationships to navigate the economic instability of the modern world. Gender roles become a way to reestablish order and identity.

In the past two decades, rising inflation, stagnant wages and housing shortages have left many people, especially younger generations, feeling economically trapped. The COVID-19 pandemic deepened these inequalities, forcing millions out of the workforce and amplifying the strain of unpaid caregiving, particularly for women.

In times of uncertainty, societies often retreat to familiar narratives. Traditional gender roles offer an illusion of stability and order, even if they reinforce inequality. The fantasy of the dependable male provider and the nurturing homemaker resurfaces because it seems to resolve anxieties that the modern economy has made harder to bear.

As a sociologist, I study these dynamics not just to understand dating trends but to trace how societies reproduce inequality through intimacy. Until our society addresses stagnant wages, rising costs and the erosion of social safety nets, I believe nostalgia for a clear, gendered hierarchy will continue. In this hierarchy, men are guaranteed women’s labor, and women hold out hope for economic security – which is often seen as romance.

Making GLP-1 weight loss drugs cheaper isn’t enough to address America’s obesity problem – here’s why

Source: The Conversation – USA (3) – By David B. Sarwer, Professor of Social and Behavioral Sciences, Temple University

Polling shows that 1 in 8 Americans have tried GLP-1 drugs. zimmytws/iStock via Getty Images Plus

The Trump administration is making a significant effort to reduce the cost of weight loss drugs. Its agreement with pharmaceutical giants, announced Nov. 6, 2025, will reduce the monthly prices of these medications by hundreds of dollars.

For the past 25 years, I have treated people with obesity and have developed and studied treatments for the condition in both adults and adolescents. One major frustration of my work is the fact that evidenced-based treatments for obesity are woefully underused

These drugs, originally approved to treat Type 2 diabetes, mimic a natural hormone called glucagon-like peptide-1 that regulates blood sugar and reduce appetite.

In my view, by making GLP-1 drugs more accessible to patients, this agreement represents one of the most significant advances the federal government has made to address obesity, one of the country’s most pressing public health issues. However, this reduced price tag alone may not make a meaningful dent in rates of obesity in American adults without additional policy changes.

Treating obesity

The Centers for Disease Control and Prevention estimates that about 40% of adults in the U.S. – more than 70 million people – have obesity. Researchers and clinicians generally define obesity based on a measure called body mass index, or BMI, which is the ratio of a person’s weight in kilograms to their height in meters, squared.

BMI is an imperfect measure, to be sure, but most medical organizations consider a person with a BMI greater than 30 to have obesity.

Between television commercials, advertisements on social media and suggestions from family and friends, Americans are bombarded by approaches to losing weight. For many of these approaches, there’s little to no evidence showing they successfully help people lose weight. However, extensive and rigorous research supports the use of GLP-1s for treating obesity. Studies show that these medications can reliably help people lose about 15% of their body weight in six to 12 months.

Evidence-based approaches for weight loss include GLP-1 drugs, surgical treatment and behavior changes such as adopting a healthier diet.

There are two other evidence based-approaches. Lifestyle changes, such as consuming fewer calories and increasing physical activity, can help people lose about 5% of their weight in the same period of time. With surgical treatment, now referred to as metabolic and bariatric surgery, patients can achieve a loss of about 30% of their body weight after about 18 months.

Which of these treatment approaches is appropriate for a given person depends on their circumstances and is best discussed with their health care provider. But in my experience, too few health care professionals refer their patients to any of these therapies.

Addressing the cost barrier

According to a November 2025 poll from the Kaiser Family Foundation, 1 in 8 adults in the U.S. have tried a GLP-1 medication. That may sound like a lot, but given that more than 40% of American adults have obesity, it may not be enough.

In clinical trials, people taking GLP-1 drugs to treat obesity generally maintained their weight loss for a year if they stayed on the medication. However, participants in the trials did not have to pay for the medications. Research suggests that more than half of people using the drugs stop taking them after six months, most often because they can’t afford them.

The federal government’s deal with Eli Lilly and Novo Nordisk aims to address this barrier.

GLP-1 drugs currently cost more than US$1,000 per month for people unable to get them covered by health insurance – and many insurance plans do not.

According to the Nov. 6 White House announcement, starting in early 2026, certain GLP-1 drugs covered by the agreement will be available for $350 per month or less through an online marketplace the government plans to launch.

Some drugs will be as cheap as $150, according to the announcement. Companies will also drop the amount that Medicare and Medicaid pay for them, and certain Medicare patients would be able to access them with a $50 co-pay.

These prices are still in flux, news reports suggest. However, for most Americans, paying even $150 a month for a single medication remains a budget buster. That’s especially true given that people from lower socioeconomic groups experience higher rates of obesity and often have other related health conditions that require costly medications.

These costs are not temporary. Most patients with obesity and related health problems will likely need to use these medications indefinitely. According to emerging research, people who stop taking them typically regain the weight they lost. Realistically, very few people who take GLP-1 drugs can maintain their weight loss with lifestyle changes alone.

Beyond cost

The reduced pricing for GLP-1 drugs is an important first step in increasing affordability and access to these treatments. Given that the food environments people live in make it difficult to make healthy choices, I believe that this move will only meaningfully benefit the health of all Americans if it is combined with other policy changes.

While several countries have a national plan to prevent and treat obesity, the U.S. does not. Instead, American public health policies are largely set state by state. They often include strategies such as free school meals for children or more robust insurance coverage for treating obesity and related health conditions. However, most such policies are often too narrow to have significant benefits at the population level.

Broader policy shifts and legislation targeting obesity prevention could move the needle.

For example, research is increasingly showing that ultraprocessed foods play a role in promoting weight gain and potentially other diseases, such as colorectal cancer. Legislators could draw on that research to better regulate these foods – for example, to limit the use of certain especially harmful ingredients, to restrict marketing of ultraprocessed products, or to limit their inclusion in school meals.

Another policy change that may help would be to build more extensive nutrition education into the training that medical students and other health care providers receive. This may better position the next generation of clinicians to help their patients make the healthiest choices to maintain their weight and health.

These and other policy changes will be critically important in efforts to reduce the rate of obesity among Americans in the future.
