The politics of the hyper-polluting private transport used by the world’s super-rich is hotting up

While millions of people make the effort to sort their recycling, buy fewer clothes and generally make greener choices, the world’s wealthiest can emit the same amount of carbon as the average person does in a year by going on holiday just once.

Among the many things worrying the climate-conscious is the question of the carbon-intensive movements of the super-rich – classed as those with more than US$30 million (£23 million) in disposable assets. This phenomenon, characterised by the use of private jets, fossil-fuelled yachts, heavy cars and space rockets, represents an enormous, and unnecessary, environmental impact.

It is estimated that the 125 wealthiest billionaires alone emit three million tonnes of carbon annually. This is close to the carbon footprint of Madagascar, a country of 30 million people.

Recent attention on the super-emitters has focused on jets, but private super-yachts are also major contributors. Despite their names, these vessels lack sails and require gigalitres of fuel to transport only a small number of crew and passengers.

Large yachts can consume hundreds of litres of fuel per hour, while super-yachts may use thousands of litres per hour even when just cruising. Yacht engines must “idle” at anchor to maintain heating and energy systems, consuming thousands of litres per week.

The yacht owned by former Chelsea FC owner Roman Abramovich, Eclipse, reportedly has a 1,000,000-litre fuel tank, while Google’s Sergey Brin’s super-yacht uses enough power to supply 580 homes, even when it is simply moored in port.

The emerging trend of private rockets also involves burning vast quantities of fuel – with no current limits on use. Former Amazon CEO Jeff Bezos’ first trip to the edge of the atmosphere reportedly produced around 93 metric tons of CO².

It has been calculated that there are 41.3 million high net worth individuals in the world, and, within this group, 510,000 ultra-high net worth individuals. Together, they are thought to possess liquid wealth of nearly US$60 trillion.

More money, more travel

This growth in private wealth has directly translated into an increase in jets and yachts and their use over time. For example, the global private super-yacht fleet has grown by 50% in about ten years and continues to see strong demand. The number of private jets has also increased substantially, leading to greater use and expansion of ground facilities at numerous airports.

The data shows the massive carbon footprints associated with the most luxurious (and unnecessary) forms of mobility utilised by the world’s wealthiest people. While many may scoff at the prospect of a human exit to Mars, this does not prevent a ramping-up of exploratory and carbon-intensive trial flights in pursuit of this mission.

Compared to the essential carbon emitted by everyday citizens going about their work and lives, the contrast is stark. It highlights how luxury and entitlement combine to create a new class of hyper-mobile carbon-emitting groups.

The expansion of the super-rich and their carbon footprint poses significant challenges to curbing emissions and fostering social unity. Inequality threatens social cohesion and has undermined the effectiveness of the political sphere, both of which are crucial for climate action.

The primary “winners” in the global political economy have been positioned as legitimate users of private jets by the aero industry on the basis that they save time that is critical to business activity. But it seems that something else is blocking action, given how publicly unpopular the use of private jets by the rich has become.

In 2024 Oxfam reported that 80% of the public support higher passenger duties on private jets and yachts. Another survey the same year showed that more than 40% of people in six European nations (UK, Germany, France, Spain, the Netherlands and Belgium) supported an outright ban on the use of private jets.

It is increasingly clear that the global climate emergency outweighs the need for “Instagram sunsets” of private super-yacht and jet users in public opinion. For brave leaders, there could be real political capital to be gained from reducing this mobility as feelings run high over waste, pollution and emissions.

Social cohesion and collective action are necessary to reduce emissions. But efforts to discourage unnecessary mobility will be challenged by powerful voices celebrating choice, individual freedoms to move and consume, and life experiences that entail massive carbon costs. The planet cannot support this outdated growth and status-conscious economic model – it must be challenged for all our sakes.

La location de jouets, une nouvelle tendance pour Noël ?

Source: The Conversation – France (in French) – By Service Environnement, The Conversation France

Et si, pour Noël, on troquait l’achat de jouets contre la location ? Moins coûteuse, plus écologique, cette solution remise au goût du jour par plusieurs marques s’inspire des ludothèques. Reste une question : tous les jouets sont-ils adaptés à ce modèle ?


Et si pour Noël, vous offriez au petit dernier des jouets de location plutôt que des objets coûteux qui finissent souvent au fond d’un placard ? L’intérêt est à la fois d’ordre économique mais aussi écologique : la durée de vie des jouets est courte. Les enfants eux-mêmes expriment une préoccupation environnementale grandissante.

Dans ce contexte, les marques de jouets commencent à proposer de nouveaux services, comme la location. Mais ces entreprises très médiatisées à la faveur de cette pratique sont-elles vraiment des pionnières ?

La ludothèque, une invention ancienne

La location de jouets existe en réalité en France depuis 1968, où a ouvert la toute première ludothèque à Dijon. Une ludothèque, mot formé à partir du latin ludus « jeu » et du grec θήκη/thḗkē « lieu de dépôt », c’est un lieu qui met à la disposition de ses membres des jouets et des jeux de société en prêt. On peut aussi jouer sur place, dans des espaces dédiés, ce qui favorise les rencontres et les liens sociaux.

Des entreprises ont ainsi eu l’idée de remettre au goût du jour ce concept. Par exemple Lib&Lou, la première plateforme de location de jouets et jeux éducatifs, créée en 2019. Elle dispose d’un partenariat avec le leader du marché de location de jeux et de matériels éducatifs écoresponsable, Juratoys, entreprise jurassienne qui propose des jouets en bois de haute qualité.

Autre acteur sur le marché, Les Jouets voyageurs proposent trois formules d’abonnements, qui permettent de choisir des jouets de seconde main dans un catalogue en ligne, puis de changer tous les mois de jouets. La marque a également développé un service de rénovation des jouets usagés, autre tendance de fond depuis la loi de janvier 2023 qui impose aux magasins spécialisés dans la vente de jouets de proposer, sans condition d’achat, un service de reprise des jouets usagés

Miljo.fr, nouvel entrant sur le marché, offre également des formules d’abonnement pour ses jouets de seconde main. La marque propose des services aux structures d’accueil de la petite enfance et aux professionnels du jouet.

Une solution gagnant-gagnant

La location de jouets présente de nombreux avantages. D’un point de vue économique, elle coûte souvent moins cher que l’achat. D’un point de vue écologique, elle permet de réduire le gaspillage et les déchets car les jouets sont réutilisés. Enfin, d’un point de vue pratique, elle évite de devoir stocker des jouets encombrants lorsque les enfants grandissent. En somme, la location de jouets est une solution gagnante pour les parents, les enfants et l’environnement.

Quelques questions restent cependant en suspens : toutes les marques peuvent-elles adhérer à ce concept, par exemple pour des questions d’hygiène ? Par exemple, une poupée Corolle en location peut-elle survivre au passage des désinfectants nécessaire pour garantir une propreté irréprochable aux futurs utilisateurs ?

De Ford à Tesla : ce que l’automobile nous apprend sur l’art de s’adapter

Source: The Conversation – France (in French) – By Norchene Ben Dahmane Mouelhi, Marketing, ESCE International Business School

De Ford à Tesla, l’histoire de l’industrie automobile et celle du management sont liées. PxHere, CC BY

L’automobile a longtemps été au centre des mutations de l’économie capitaliste. Ce secteur a même inventé des modes de management : du fordisme au toyotisme. Sans oublier le controversé Tesla et son dirigeant aussi connu que sujet de critiques. Mais qu’en est-il vraiment ?


Ford, Toyota, Tesla… Derrière ces marques emblématiques se cachent des modèles de gestion et de management enseignés dans les écoles de commerce. Le contexte historique de chaque modèle impose aussi de s’adapter et de se renouveler.

Le fordisme : un premier modèle critiqué

En 1913, Henry Ford propose de lancer la Ford T comme modèle unique de voiture, proposée en une seule couleur : « Le client peut avoir une voiture de la couleur qu’il veut, tant qu’elle est noire ». Il va alors mettre en place un système de travail à la chaîne inspiré des abattoirs de Chicago en proposant que ce ne soit plus l’ouvrier qui se déplace mais la voiture qui vienne à l’employé posté.

Cette idée révolutionnaire, désignée par le terme d’« organisation scientifique du travail » (OST), a permis à l’entreprise un gain sur le temps de production (en passant de 12 heures à 93 minutes) avec un prix plus abordable (de 850 dollars à 260 dollars). Un an après, en 1914, Ford propose d’augmenter les salaires des employés à 5 dollars par jour pour leur permettre d’acheter les voitures qu’ils fabriquent. La Ford T devient alors l’une des voitures les plus vendues dans le monde. Cependant, ce modèle de production, aliénant et déshumanisé, ne tarde pas à subir des critiques, immortalisées par Charlie Chaplin en 1936 dans son film les Temps Modernes.

Et General Motors inventa le contrôle de gestion

Face à l’uniformisation excessive promue par le système de Ford, Alfred Sloan, président de General Motors en 1923, propose cinq marques, allant de Chevrolet à Cadillac, et plusieurs modèles adaptés à différents segments du marché et clients. C’est lui qui inventera le contrôle de gestion : un système où chaque marque devient un « centre de profit » autonome, le siège fixant les grandes lignes et les stratégies du groupe. Pour Sloan, il est important de « centraliser grâce à la décentralisation » ou encore « décentraliser les opérations, centraliser le contrôle ». Ce modèle de management permettra à GM de rester leader de son marché pendant 77 ans.

Le Kaizen par Toyota

Dans un contexte de post-guerre en 1950 où le Japon essaye de se reconstruire, Kiichiro Toyoda et l’ingénieur Taiichi Ohno se fixent comme défi de trouver un modèle de management novateur qui pourrait détrôner le fordisme. La production massive associée à ce premier modèle d’organisation du travail est jugée inadaptée à leur petit pays. Ils décident donc de produire à la demande ce qui est commandé, sans gaspillage. Ils suggèrent alors le Kaizen, un processus d’évaluation dans lequel chaque employé peut suggérer des améliorations. Ce sont les prémices du cercle de qualité en méthode de gestion. Cette philosophie pousse les individus à se surpasser avec des petits pas et le désir permanent de l’amélioration continue.

Ce concept a été vulgarisé en 2024 par Inoxtag, un jeune youtubeur qui ne pratiquait pas de sport, qui se fixe alors le défi de se challenger et de gravir l’Everest dans un documentaire vu par plus de 43 millions de personnes.

Stellantis ou le géant aux 14 marques

L’exemple du groupe Stellantis met en lumière la difficulté de gérer différentes marques, différentes usines dans différents pays avec des cultures différentes. En 2021, PSA Fiat et Chrysler ont fusionné.

Carlos Tavares, à la tête du groupe, a choisi une approche darwinienne selon laquelle chaque marque peut se gérer seule et être rentable ou disparaître. Il fallait dans ce contexte gérer un paradoxe : partager une chaîne de valeur éclatée par pôle d’expertise et commune à toutes les marques du groupe Stellantis, tout en cherchant à différencier les marques au détriment du contrôle de la chaîne de valeur. Cette situation reflète bien la réalité du XXIe siècle où le management devient une affaire de survie des entreprises et non pas seulement de performance.

Tesla : le management disruptif controversé

Si de nombreuses entreprises ont adopté un management disruptif, Tesla a une valeur d’exemplarité dans le secteur automobile. Fondée en 2003, elle fonctionne en mode start-up, à savoir comme une entreprise technologique qui mise sur l’innovation pour s’adapter à l’évolution du marché de l’automobile. Elon Musk, son dirigeant depuis 2004, va jusqu’à livrer lui-même les voitures à certains clients privilégiés. Ceci est difficilement transposable à l’international.

Arts et métiers Alumni, 2019.

La recherche-développement est aussi au cœur du modèle de management de Tesla (Tesla dépense en R&D 5 203 euros contre 1 000 euros chez la concurrence). Certains critiquent Tesla et notamment les conditions de travail controversées, le fait par exemple que la plupart des composants de la voiture soient chinois ou la gestion financière fragile. Il est aussi à noter que la concurrence (Mercedes, Audi, BMW, Aston Martin) s’est lancée dans une véritable course de production d’automobiles électriques, notamment face à la domination des entreprises chinoises.

De quoi sera fait demain ?

De 1903 à aujourd’hui, de Ford à Tesla en passant par Toyota, GM ou Stellantis, on peut voir que tous ces exemples révèlent qu’il est possible de voir que les révolutions opérées ne sont pas brutales, il est important d’évoluer et de s’adapter.

Le management lui aussi n’est pas figé dans le temps. Chaque modèle managérial est la résultante de plusieurs paramètres en partant d’un mécanisme spécifique à un contexte, un pays, une période, une culture.

Comment pictogrammes et émojis traitent la question du genre

Source: The Conversation – France in French (3) – By Jonathan Groff, Docteur en psychologie, Université de Technologie de Troyes (UTT)

Les pictogrammes fabriquent du masculin par défaut, mais pas les émojis : pourquoi ? Daiki Sato/Unsplash, CC BY

Pensés pour être universels, les pictogrammes racontent une histoire moins neutre qu’il n’y paraît. Au fil des normes et des usages, la figure de l’homme s’est silencieusement imposée. Comment cette évidence graphique s’est-elle construite ? Du côté des émojis, une sous-catégorie du système iconique, la situation est moins androcentrique – et ce n’est pas seulement parce qu’ils sont apparus plus récemment. Comment s’en inspirer pour rendre les pictogrammes plus représentatifs de l’ensemble de la société ?


Ils recouvrent nos écrans, ponctuent nos correspondances et investissent l’espace public : les pictogrammes. Conçus pour exprimer des concepts simples, immédiatement déchiffrables, ils sont utilisés dans le but de « communiquer des informations nécessaires indépendamment de toute langue ». Pour autant ils ne sont pas neutres. Ils peuvent être les vecteurs d’androcentrisme graphique. L’androcentrisme désigne une propension à considérer « l’humain » ou « le générique » par le prisme exclusif du masculin.

Cette forme de stéréotype de genre appliqué aux pictogrammes apparaît dans la littérature scientifique, tout particulièrement dans les recherches des trente dernières années. Cette période correspond à une époque d’intensification des échanges internationaux qui s’est traduite par une circulation accrue de normes visuelles. D’autre part, elle coïncide avec une phase de démocratisation des outils informatiques qui a entraîné une multiplication des pictogrammes.

Les transports publics les exploitent, notamment pour communiquer des informations intelligibles rapidement. C’est justement à l’occasion de travaux menés dans la filière ferroviaire et destinés à évaluer la compréhension de messages pictographiques que j’ai supposé l’existence de stéréotypes dans ce milieu. Pour comprendre comment se diffusent ces biais, il était cependant nécessaire d’élargir le champ d’étude à un domaine mieux documenté : le genre.

Mon analyse porte sur les environnements où les pictogrammes sont les plus nombreux, les plus exposés et les plus fréquemment utilisés – les hôpitaux et la signalisation routière (l’un des premiers secteurs à avoir fait l’objet d’une normalisation et dont les codes tiennent toujours lieu de modèles en matière de signalétique).

Ces pictogrammes qui nous guident… et perpétuent des stéréotypes

Les transports, terrain propice à l’iconographie, n’ont pas échappé à la diffusion de stéréotypes de genre, aujourd’hui encore ancrés dans les standards. Une étude récente portant sur 227 pictogrammes routiers provenant de plusieurs pays a ainsi mis en évidence une prédominance de figures masculines sur les profils féminins et neutres.

Comme je l’avais observé dans le monde ferroviaire, ce déséquilibre varie selon le type de panneaux. Ceux qui évoquent des passages d’enfants, comptent davantage d’images féminines, comparés aux passages piétons ou travaux, qui représentent quasi exclusivement des hommes. Lorsqu’il apparaît, le féminin se limite généralement à des icônes de fillette accompagnée. Un seul (sur 227) la montre indépendante.

Motel, Peck, 2018, CC BY

Point de référence, le système de signalisation routière voit ses biais reproduits dans d’autres univers visuels. Dans les espaces publics, par exemple les aéroports, cette tendance se confirme avec une nuance. Les femmes ne sont pas totalement absentes mais semblent confinées à des fonctions d’assistance (ex. prendre soin d’un bébé). Dès qu’elles sont associées à un ou plusieurs hommes, elles sont renvoyées au second plan (ou matérialisées dans des proportions plus réduites).

Cette récurrence invite à interroger les mécanismes mêmes de production des pictogrammes et plus précisément les banques d’illustrations mises à disposition par les organismes de normalisation. Dans beaucoup d’entre elles, les femmes sont peu présentes ou cantonnées à des rôles subalternes. Par exemple, la norme ISO 7010, qui régit la conception des symboles de sécurité, fait principalement appel à des figures masculines.

Il en est de même dans le secteur du handicap, où les icônes sont majoritairement composées d’hommes (ex. 89 % sur un échantillon de 40, dont 28 personnages) alors que les femmes constituent 56 % des personnes en situation de handicap âgées de 16 ans ou plus et vivant à domicile.

Au-delà des lieux publics, les tableaux de bord électroniques (ex. grues, machines de production, hôpitaux) ont largement participé à la propagation des stéréotypes de genre dans la pictographie. Le domaine médical en est un exemple. Des symboles sont couramment employés pour désigner l’activation de commandes, chez les professionnels (ex. moniteurs de signes vitaux) comme chez les patients (ex. télécommandes de chevet).

Dans une étude menée en 2019 et couvrant 8 pays, 56 appareils d’appel de soignants ont été comparés. Parmi eux, 37 recouraient à des figures féminines pour illustrer le concept d’assistance. Neuf étaient neutres et dix sans illustration. Une telle distribution suggère une association automatique entre la femme et la notion d’assistance, et par extension une orientation genrée du processus de codage iconographique.

Les émojis : un modèle de gouvernance distinct

Le numérique n’échappe pas à cette logique même si des progrès sont notables.

Ainsi, dans une étude menée en 1997 et portant sur 14 000 cliparts (représentations simplifiées d’un concept, d’un objet, d’une personne, d’une situation) les femmes ne constituaient que 4 % des items, souvent secrétaires ou infirmières.

Si les améliorations restent globalement limitées, des transformations positives se dessinent dans une autre branche proche des pictogrammes, plus populaire : les émojis.

En 2016, le consortium Unicode, chargé de normaliser l’encodage du texte et des symboles, a entrepris une révision de son système en faveur de la diversité. Onze nouveaux émojis décrivant des femmes en activité (ex. programmeuses, scientifiques) sont venus s’ajouter à la féminisation de 33 items existants (ex. espionnes, surfeuses). Des sociétés comme Google ont introduit des figures féminines dans des rôles valorisés (ex. scientifique, médecin).

Des emojis représentant des femmes dans des métiers valorisés.
Unicode

Ces trajectoires distinctes entre pictogrammes et émojis pourraient en partie s’expliquer par leurs modèles de gouvernance. Du côté des pictogrammes, celui-ci est dispersé : certaines normes sectorielles (ISO, par exemple) coexistent avec de vastes banques de symboles libres (notamment Noun Project), sans qu’aucune instance unique ne fixe définitivement les usages. Du côté des émojis, il est plus centralisé. Une forme de standardisation est assurée par le Consortium Unicode, une organisation soutenue par des entreprises technologiques (dont Google), qui reconnaissent son autorité et contribuent ainsi à renforcer son rôle dans l’uniformisation des caractères numériques.

En clair, les émojis suivraient un processus formalisé de propositions et de standardisation qui rend possible l’introduction de modificateurs (ex. genre). À l’inverse, la construction des pictogrammes, en particulier dans le monde logiciel, serait atomisée entre une multitude de systèmes graphiques qui ne bénéficient d’aucun effort collectif comparable.

Et après ? Rendre les pictogrammes réellement universels

Les démarches entreprises dans le contexte des émojis laissent entrevoir plusieurs axes d’amélioration pour les pictogrammes. Ainsi, une approche de création empirique et standardisée serait susceptible de limiter les effets de l’androcentrisme graphique.

Empirique d’abord : s’appuyer sur des méthodes et outils scientifiques permettrait de mesurer de manière quantitative l’ampleur des biais et d’estimer leur impact sur le public dans le but de définir des lignes directrices respectueuses de l’égalité.

Standardisée ensuite : en combinant les recommandations d’organisations reconnues (ex. Unicode), les travaux d’instituts de normalisation (ex. ISO) et les initiatives individuelles (ex : designers indépendants), la diversité des représentations se trouveraient renforcées.

En tant que signe visuel simple, intelligible de tous et omniprésent, le pictogramme contribue à propager une certaine forme d’androcentrisme. De fait, pour s’assurer qu’elle réponde à sa promesse d’universalité et éviter qu’elle ne véhicule des stéréotypes, la communication pictographique implique un questionnement du prisme masculin « par défaut ». Cette étape suppose l’établissement concerté de nouveaux référentiels, couplé à une évaluation continue des normes de conception.

More dialogue, less debate: At an ‘Ethics Bowl,’ students learn to handle tough conversations

Source: The Conversation – Canada – By Rackeb Tesfaye, Knowledge Mobilization Lead and Senior Scientist at the Bridge Research Consortium, Simon Fraser University

As Canadian federal election candidates prepared for their final debate in April 2025, youth across the country were preparing for collaborative conversations around timely and potentially divisive issues for the National Ethics Bowl at the Canadian Museum of Human Rights in Winnipeg.

Ethics Bowl Canada is a non-profit organization that hosts competitions where high school and university students explore complex ethical issues through respectful dialogue in teams.

Rather than trying to undermine their opponents’ arguments, as in traditional debates, Ethics Bowl competitors win by engaging constructively, responding positively to reasonable criticism and refining or amending their views.

Polarization and engaging with disagreement

The Public Policy Forum’s 2023 report Far and Widening: The Rise of Polarization in Canada documented serious issues around how young people think about their futures. It highlighted that, among young people’s concerns like pandemics, climate emergencies and a declining economy, their deepest fear for Canada’s future is growing political and ideological polarization.

The erosion of trust in institutions like government, industry and media contributes to people seeking alternative sources of information.

Alternative sources sometimes contribute to healthy social empowerment and democratic participation. But we are also living with cascading misinformation — sometimes sewn by groups seeking to destabilize society — with harmful effects. Through algorithmic filtering we’ve seen a growth of ideological echo chambers.

Philosophers like John Stuart Mill, John Rawls and Seyla Benhabib have long proposed that engaging with diverse and sometimes contrary points of view is part of what legitimizes democracy.

Conflict and disagreement are healthy parts of a democracy. But these need to be engaged with productively.

How the Ethics Bowl works

The Ethics Bowl is a “gamified” way of engaging in deliberative dialogue about civic issues. More than 1,500 high school and university students now participate in Ethics Bowls each year.

Ethics Bowl teams conduct research on cases created by philosophers and subject matter experts, and then form their opinions and arguments on them. Teams of three to five students then participate first in regional competitions, where they present their arguments, listen to other arguments, provide comments and respond to feedback.

A panel of judges (including philosophers, subject matter experts and community members) scores the teams. Their rubric rewards acknowledging nuance, refining positions and being respectful. Regional winners then compete nationally.

Evidence shows thinking and talking about ethics alone can be a driver for social change. The Ethics Bowl is also an intervention that allows participants to develop their civic discussion skills.

Research shows that engaging in this kind of dialogue can help participants acquire civic virtues, such as tolerance, respect for diverse viewpoints and willingness to engage in conversation.

Vaccines as a timely topic

While the legitimization of anti-vaccine rhetoric continues in the United States, Canada is not immune to divisiveness around vaccines.

Since the pandemic, Canada has seen a rise in vaccine hesitancy, a resurgence of measles and a shift in COVID-19 vaccine accessibility.

Among young people in Canada, vaccination is now one of the most polarizing topics of discussion.

To support young people reflecting upon ethical tensions around vaccines, Ethics Bowl Canada partnered with the Bridge Research Consortium (BRC), a national consortium of social scientists and humanity scholars. BRC scholars have a broad range of expertise to support public trust and equitable access to new vaccines.

Vaccine case studies

BRC Bioethicists developed timely case studies for the National Ethics Bowl:

Participants in the National Ethics Bowl found these cases the most challenging in the competition. One participant said:

“Public health is not something we often think about.”

A graphic illustration visually captured the many themes and reflections emerging from six teams discussions, and a version with links to the case studies is available on the Ethics Bowl website.

Engaging in civil dialogues is a transformative experience for students. As one teacher explained:

“These discussions matter. This type of dialogue has the power to change individuals.”

They also contribute to a sense of belonging. One high school student shared:

“Being around people who care about real world issues feels good.”

An educational model to train scientists

Scientists have also been caught in the crosshairs of political partisanship on vaccines. Despite a decline of trust in many institutions, scientists are still trusted sources of information by the public globally.

As evidenced by the COVID-19 pandemic, confidence in and the adoption of immune-based innovations moves at the speed of trust. Yet, rather than a loss of trust, scientists are losing influence to other information sources.

The need for scientists to strengthen trust and resonate with the public among the sea of other voices was addressed by a second mini Ethics Bowl with science graduate students in Montréal in June 2025. Before the event, 86 per cent of the science graduate students indicated they rarely or sometimes discussed the ethical implications of their work.

Student participants were part of RAMP-UP, a Québec-based research initiative developing reliable, scalable and adaptable biomanufacturing processes to produce vaccines and immunotherapies ahead of a future health emergency.

This mini ethics bowl was a teaching and learning tool to support students’ deeper engagement with the moral and ethical implications of their work, and to instil more socially informed science engagement.

Science researchers deliberate ethical concepts

As part of the full day of the mini Ethics Bowl training, students were introduced to ethical and philosophical concepts and engaged with experts in multiple disciplines. They competed in an Ethics Bowl with their peers discussing the above described vaccine-related case studies.

As captured in an illustration of events, not only did students feel stimulated and learn new knowledge, they came away calling for more integration of the social sciences and humanities in their education.

They also reflected on other ethical tensions in their work — like pharmaceutical companies profiting from their research.

We recommend this novel model of learning be introduced into curricula for scientists working on polarizing topics like immunology.

How to engage in productive dialogue

From election periods to holiday dinners with family, here is a blueprint for how people can collectively engage in productive dialogues:

1. Disagreement isn’t a failure: Instead of viewing someone disagreeing with you as having failed in some way (perhaps by being irrational), view them as an intellectual equal. Rational processes can result in more extreme (farther in content from other opinions) and radical (more strongly held) opinions. The processes that produce more extreme and radical opinions can also work on you.

2. Listen and try to understand: Be curious about, and interested in, interpreting what your conversation partner is saying with empathy. This can allow you to evaluate their points more fairly. Empathizing might allow you to better understand where others are coming from.

3. Set realistic expectations: People rarely change their minds during a conversation. But if sustained conversation focuses on practical issues, as opposed to foundational values, parties change their minds more often while reflecting between conversations.

Cem Erkli, program co-ordinator for Ethics Bowl Canada, and Pierre-Jean Alarco, knowledge mobilization officer for RAMP-UP, co-authored this story.


Immunity and Society is a new series from The Conversation Canada that presents new vaccine discoveries and immune-based innovations that are changing how we understand and protect human health. Through a partnership with the Bridge Research Consortium, these articles — written by experts in Canada at the forefront of immunology, biomanufacturing, social science and humanities — explore the latest developments and their impacts.

Seven of the best novels of 2025 – chosen by our literary experts

Source: The Conversation – UK – By Tessa Whitehouse, Reader in 18th-century Literature and Director of Queen Mary Centre for Religion and Literature, Queen Mary University of London

Reading is very subjective, but one thing most book lovers can agree on is that 2025 was a notable year for fresh, inventive, affecting storytelling. Books translated from their original language are proving increasingly popular as readers seek out global perspectives beyond their own, as evidenced in this year’s International Booker win, Heart Lamp by Banu Mushtaq, which is included here.

We also bring you five other novels our academic experts have chosen as their favourites this year. From a Mrs Dalloway for the service economy, to a dreamlike encounter between people across time, place and mortality, do our academic picks chime with yours?

Pick A Colour by Souvankham Thammavongsa

This slender little novel is both a reverie and a dash of icy water to the face that will make you think twice about tuning out from your surroundings next time you get a mani-pedi. We follow the owner of a low-price nail bar through a workday from turning on the fluorescent lights to pulling down the metal shutter.

In this Mrs Dalloway for the service economy, the painful intersections of the personal and the political are inescapable for the “Susans” (the name each employee must adopt), but as invisible as the workers themselves to many of their customers.

Slight in length, light in touch, full of humour, and closely observed, Pick A Colour can be read in a single, intense afternoon. But the troubling thoughts it raises through its memorable characters linger long after your Christmas nail polish has all chipped away.

Perfection by Vincenzo Latronico

Perfection is a curious sort of novel. There is no dialogue and almost no conflict between the two central characters, Anna and Tom, digital nomads who spend their days in Berlin designing websites and always appear together, almost like a single entity.

In a sequence of beautifully written, perfectly observed chapters, Latronico itemises and describes their apartment, their social media habits, their limited perspective on Berlin, their sex life, their futile attempts at meaningful political activism, their growing disillusionment and desire for relocation – the repetitive consumption and socially structured habits of a globalised lifestyle built around image and taste.

The result is a remarkably astute and compelling novel – social realism at its sharpest – as Latronico nails the manners of the millennial generation and that brief period of optimism, from 2006 to 2016, when we felt digital media might make a positive difference and lifestyle choices seemed imbued with an optimistic ethical resonance – soon shown to be hollow.

Old Soul by Susan Barker

At first, Barker’s novel seems a gorgeously written adaptation of one of my favourite gothic tropes: the vampire. The story opens with two strangers, Jake and Mariko, who meet at Osaka airport. They have both lost loved ones in strange and brutal circumstances but in common, each of the deceased encountered a mysterious, dark-haired woman just before their deaths. A woman who came looking for Mariko, and then disappeared.

As the plot advances, Barker takes familiar tropes and themes in unexpected directions, turning this novel into an unforgettable tale of cosmic horror. There is the terrifying lore of “the Tyrant”, different timelines and settings from Wales to New Mexico, not to mention a cast of unreliable narrators who become more vibrant, twisted and compelling as the novel advances. Ultimately, this is a story about our societal obsession with becoming famous and being seen – Barker’s novel goes a step further and asks: who gets to witness? Who gets to record? And for what purpose?

Big Kiss, Bye-Bye by Claire-Louise Bennett

There is no shortage of contemporary novels with first-person narrators who are women, often writers, struggling to keep themselves together in the face of late capitalism, the internet and the patriarchy. Claire-Louise Bennett’s Big Kiss, Bye-Bye is narrated by a woman, a writer, but beyond that, all similarities to other works in this category disappear.

The narrator’s interior world is made up of thoughts about and responses to others – her friend and ex-lover Xavier, her old schoolteacher with whom she had a relationship as a teenager, and another old schoolteacher who has recently emailed her.

It is a novel of extraordinary noticing, but it is a noticing that has such rhythm and intensity that it enters your very bones as you read. It is as unrepeatable as a dream, and like a dream stays with you way beyond the ability of words to account for it.

We Do Not Part by Han Kang

The English translation of We Do Not Part followed Han Kang’s 2024 Nobel Prize in Literature. Her earlier Greek Lessons (2011, translated into English 2023) considered loss of sight and speech through the arresting metaphor of burial in snow.

We Do Not Part reconsiders this metaphor, employing the destructive and creative force of a snowstorm to convey the danger of lost histories. Kyungha reluctantly agrees to house sit and look after the much-loved pet bird of her sick friend, Inseon, and travels in snow and darkness to reach her rural cabin.

The novel is at once a dreamlike encounter between people across time, place, and mortality; a recollection of the women’s friendship and childhoods; a personal history of the impact of the 1948-49 Jeju massacre (an intense period of anti-communist violence and suppression that resulted in thousands of deaths); and a portrait of the rural South Korean landscape in bleak winter. The prose is crisp and poetic, the dialogue sparse, and the protagonist introspective and self-questioning. An intelligent, graceful, bruising novel and an encounter with the rural and the local.

Dream Count by Chimamanda Ngozi Adichie

At a time when many literary novels are becoming shorter and increasingly opaque, the luminous Dream Count – Adichie’s first novel in a decade – bucks the trend. Expansive and richly detailed, it follows the lives of four African women, moving fluidly between the US and Nigeria.

Set at the onset of the Covid pandemic, the pause in ordinary life creates space for the women to reflect and dream, deepening the novel’s engagement with memory and personal history alongside its comparative exploration of women’s experiences in different parts of the world.

Like many recent novels, films, and television series (Conversations with Friends; Girl, Woman, Other; Derry Girls), the women here both contrast and complement one another, offering nuanced insight into what it means to be Black and female and with varying degrees of privilege.

The novel skilfully intertwines universal aspects of the female experience, such as cultural pressure to marry and produce children, with a post-#MeToo focus on sexual violence rooted in stark racial and gendered power inequalities.

Heart Lamp by Banu Mushtaq

Delicately woven over a period of 33 years, this collection of 12 short stories comes from the heart of the Muslim community in southern India. Rendered nearly invisible in the nation’s literary imagination despite its substantial presence, Heart Lamp offers a necessary intervention into the silences of Indian Muslim women’s interior lives.

It maps the emotional landscapes and the intricate layers of marginalisation through caste, class and gender expectations embracing the politics of location. Mushtaq, an activist, inevitably represents Karnataka’s “Bandaya Sahitya” (Rebel Literature) movement, rooted in anti-caste, feminist and secular traditions.

The stories juxtapose modern India’s patriarchal structures with the obscured lives of women through literal and metaphorical veils where pain, suffering, injustice are critiqued through razor sharp realism mingled with sentimentality and humour. Deepa Bhasthi’s translation performs its own quiet rebellion, refusing to italicise Kannada words or append footnotes.

En 2025, voici comment l’inflation a fragilisé la stabilité politique et sapé les fondements moraux de notre société

Source: The Conversation – in French – By Mircea Vultur, Professeur titulaire et chercheur en sociéconomie du travail et de la formation, Institut national de la recherche scientifique (INRS)

Depuis quelques années, le coût de la vie ne cesse d’augmenter. Nourriture, essence, logement : tout semble plus cher, et l’inflation dépasse les simples chiffres économiques. Elle réduit le pouvoir d’achat, brouille les signaux du marché et fragilise la confiance dans l’État, transformant une hausse des prix en véritable enjeu social et politique.

Selon la définition la plus répandue aujourd’hui, l’inflation est une hausse soutenue du niveau de prix. On la mesure par l’évolution d’un indice du prix à la consommation (IPC), calculé à partir des prix de marché d’un certain nombre de biens de consommation censés être représentatifs des habitudes de consommation de la population.

Au Canada, l’inflation est restée modérée jusqu’au début des années 2020. La pandémie de Covid-19 l’a fait chuter temporairement, avant un rebond marqué en 2021‑2022, atteignant son plus haut niveau depuis 40 ans. Depuis, elle redescend progressivement, mais reste au-dessus de la moyenne observée avant la crise, autour de 2,4 % en septembre 2025, selon Statistique Canada.

Après deux décennies de stabilité autour de 2 %, le choc inflationniste de 2021‑2023, et les risques qui subsistent, ne se limitent pas à un phénomène économique : l’inflation devient une véritable pathologie sociale, puisqu’elle affecte directement la société. Son caractère destructeur dépasse la simple hausse des prix : elle réduit le pouvoir d’achat, influence les comportements d’épargne, modifie les stratégies d’investissement et façonne la perception que les citoyens ont de l’État et des institutions financières.

À cet égard, l’inflation agit comme un révélateur. Lorsque les prix s’emballent, les fragilités économiques, institutionnelles et psychologiques d’une société apparaissent au grand jour. Ainsi, la hausse du prix du logement a transformé une donnée économique en source de stress, de renoncements et parfois d’instabilité sociale. On le voit aussi lorsque les consommateurs se précipitent pour acheter avant une nouvelle hausse de prix. Ces comportements collectifs, motivés par la peur, illustrent comment l’inflation trouble les repères sociaux.

Une érosion silencieuse du contrat social

L’inflation agit comme une « taxe furtive » qui contourne le débat démocratique. Elle réduit le pouvoir d’achat de tous sans débat parlementaire ni avis officiel. Contrairement aux taxes « visibles » qui doivent être adoptées, argumentées et justifiées, l’inflation agit dans l’ombre. Une hausse généralisée des prix de 10 % réduit la valeur réelle de chaque dollar de 10 %, même pour ceux qui n’ont rien consommé. Aucun reçu, aucun document officiel ne signale cette perte. On se réveille un bon matin simplement moins riche.

L’inflation agit comme une redistribution invisible de richesses, mais de façon arbitraire. Certains en bénéficient, d’autres en pâtissent. Les emprunteurs y gagnent, car leurs dettes perdant de la valeur réelle, tandis que les épargnants prudents y perdent. Les actifs réels deviennent des refuges, tandis que les salaires fixes et les retraites non indexées s’érodent. Cette redistribution chaotique crée un sentiment d’injustice et dévalorise l’effort, l’épargne et la prudence.

Des signaux économiques brouillés

Dans une économie de marché, les prix servent de signal : ils indiquent si un bien est rare, très demandé ou coûteux à produire, et guident les décisions d’investissement. L’inflation brouille ces signaux. Par exemple, si le prix des loyers à Montréal augmente fortement, certains promoteurs pourraient croire que la demande est énorme et construire de nouveaux appartements, alors qu’en réalité, cette hausse reflète surtout la pression générale des prix et le coût croissant des matériaux.

Quand les prix ne reflètent plus la réalité de la demande, les investissements peuvent être mal orientés et les ressources gaspillées.

Par ailleurs, l’incertitude inflationniste décourage l’épargne et pousse les entreprises vers des stratégies court-termistes. Une société qui peine à se projeter dans l’avenir investit moins dans l’innovation, les infrastructures ou la formation, ce qui freine sa croissance économique et compromet son développement à long terme.

Méfiance de l’État et résurgence des tensions politiques

La monnaie repose sur un pacte implicite entre les citoyens et l’État : un dollar gagné aujourd’hui doit permettre une consommation quasi équivalente demain. Lorsque ce pacte est rompu, la confiance s’effrite et l’État apparaît de moins en moins comme l’agent des citoyens, mais plutôt comme un maître indigne de confiance.

Dans ce contexte, les épisodes d’inflation forte coïncident souvent avec des tensions politiques : mouvements de protestation, contestation de la classe politique, polarisation sociale, montée du populisme comme réponse. Au Canada, des appels de boycottage de supermarchés ont émergé face à la flambée des prix alimentaires, tandis que la crise du logement a entraîné des pressions pour imposer des gels et plafonds de loyers. En Argentine, l’inflation chronique alimente la défiance envers les institutions, provoque des alternances politiques brusques et renforce l’attrait pour les solutions populistes. Avec les prix de l’épicerie, du logement et de l’essence en tête, la frustration économique se transforme rapidement en colère politique.

Le rôle central de la politique monétaire

Pour les économistes de l’école autrichienne, l’inflation provient d’une augmentation trop rapide de la quantité d’argent en circulation par rapport à la production réelle. Dans la perspective de l’École de Chicago, elle est toujours un phénomène monétaire : les gouvernements utilisent parfois l’impression de monnaie pour financer des dépenses, repoussant les problèmes économiques plutôt que de les résoudre directement.

L’économiste Milton Friedman comparait l’inflation à l’alcoolisme : les effets bénéfiques apparaissent d’abord, mais les conséquences négatives arrivent plus tard, et la tentation d’en faire trop est forte.

Déficits publics financés par création monétaire, banques centrales trop accommodantes et volonté politique d’alléger la dette sont des moteurs classiques de l’inflation. La solution ? Empêcher les gouvernements d’utiliser la création monétaire comme levier politique. La réforme de 1991 illustre ce principe : l’indépendance accrue de la Banque du Canada et un mandat clair de contrôle de l’inflation ont permis de maintenir durablement les prix à des niveaux bas et stables.

Dans cette perspective, il est essentiel de garantir l’indépendance des banques centrales pour les protéger des pressions politiques, d’imposer des limites strictes aux déficits publics et d’assurer une transparence totale de la politique monétaire. Pour les économistes « autrichiens » comme pour Friedman, la stabilité monétaire est la condition sine qua non de toute stabilité économique et sociale.

Qualifier l’inflation de « pathologie sociale » n’est pas exagéré. Elle érode la confiance, bouleverse l’équité, fausse l’allocation des ressources et fragilise la stabilité politique, sapant les fondements moraux d’une société. L’expansion monétaire qui la provoque est une fuite en avant, un culte du compromis, repoussant les problèmes vers les générations futures. Le choc récent et les tendances actuelles rappellent que même nos sociétés industrielles avancées restent vulnérables. Comprendre l’inflation et ses effets sociaux aide à en mesurer la portée et à mieux s’y préparer.

No, your brain doesn’t suddenly ‘fully develop’ at 25. Here’s what the neuroscience actually shows

Source: The Conversation – Canada – By Taylor Snowden, Post-Doctoral Fellow, Neuroscience, Université de Montréal

If you scroll through TikTok or Instagram long enough, you’ll inevitably stumble across the line: “Your frontal lobe isn’t fully developed yet.” It’s become neuroscience’s go-to explanation for bad decisions, like ordering an extra drink at the bar or texting an ex you swore not to.

The frontal lobe plays a central role in higher level functions like planning, decision-making and judgment.

It’s easy to find comfort in the idea that there’s a biological excuse for why we sometimes feel unstable, impulsive or like a work in progress. Life in your 20s and early 30s is unpredictable, and the idea that your brain simply isn’t done developing can be oddly reassuring.

But the idea that the brain, particularly the frontal lobe, stops developing at 25 is a pervasive misconception in psychology and neuroscience. Like many myths, the “age 25” idea is rooted in real scientific findings, but it’s an oversimplification of a much longer and more complex process.

In reality, new research suggests this development actually extends into our 30s. This new understanding changes how we view adulthood and suggests that 25 was never meant to be the finish line in the first place.


No one’s 20s and 30s look the same. You might be saving for a mortgage or just struggling to pay rent. You could be swiping dating apps, or trying to understand childcare. No matter your current challenges, our Quarter Life series has articles to share in the group chat, or just to remind you that you’re not alone.

Read more from Quarter Life:


Where did the ‘age 25’ myth come from?

The magic number stems from brain imaging studies in the late 1990s and early 2000s. In one 1999 tudy, researchers tracked brain changes through repeated scans in children and teens. They analyzed grey matter, which consists of cell bodies and can be thought of as the “thinking” component of the brain.

Researchers found that during the teenage years, grey matter goes through a process called pruning. Early in life, the brain builds an enormous number of neural connections. As we age, it gradually trims back the ones that are used less often, strengthening those that remain.

This early work highlighted that grey matter volume growth and loss is key for brain development.

In influential follow-up work led by neuroscientist Nitin Gogtay, participants as young as four had their brains scanned every two years. The researchers found that within the frontal lobe, regions mature from back to front.

More primal regions, like areas responsible for voluntary muscle movement, develop first, while more advanced regions that are important for decision-making, emotional regulation and social behaviour had not fully matured by the final brain scans around age 20.

Since the data stopped at age 20, researchers couldn’t say precisely when development finished. The age of 25 became the best estimation for the assumed endpoint, and eventually became enshrined in the cultural consciousness.

What newer research reveals

Since those early studies, neuroscience has moved on considerably. Rather than looking at individual regions in isolation, researchers now study how efficiently different parts of the brain communicate with one another.

A recent major study assessed efficiency of brain networks, essentially how the brain is wired, through white matter topology. White matter is made up of long nerve fibres that link different parts of the brain and spinal cord, allowing electrical signals to travel back and forth.

Researchers analyzed scans from more than 4,200 people from infancy to 90 years old and found several key periods of development including one from age nine to 32, which they coined the “adolescent” period.

For anyone well into adulthood, it may feel jarring to be told that your brain is still an “adolescent,” but this term really just signifies that your brain is in a stage of key changes.

Based on this study, it seems that during brain adolescence, the brain is balancing two key processes: segregation and integration. Segregation involves building neighbourhoods of related thoughts. Integration involves building highways to connect those neighbourhoods. The research suggests this construction doesn’t stabilize into an “adult” pattern until the early 30s.

The study also found that “small worldness” (a measure of network efficiency) was the largest predictor for identifying brain age in this group. Think of this like a transit system. Some routes require stops and transfers. Increasing “small worldness” is like adding express lanes. Essentially, more complex thoughts now have more efficient paths throughout the brain.

However, this construction doesn’t last forever. After around the age of 32, there is a literal turning point where these developmental trends switch directions. The brain stops prioritizing these “expressways” and shifts back to segregation to lock in the pathways our brains use most.

In other words, your teens and 20s are spent connecting the brain, and your 30s are about settling down and maintaining your most used routes.

Making the most of a brain under construction

If our brains are still under construction throughout our 20s, how do we make sure we are building the best possible structure? One answer lies in boosting neuroplasticity — the brain’s ability to rewire itself.




Read more:
What is brain plasticity and why is it so important?


While the brain remains changeable throughout life, the window from age nine to 32 represents a prime opportunity for structural growth. Research suggests there are many ways to support neuroplasticity.

High-intensity aerobic exercise, learning new languages and taking on cognitively demanding hobbies like chess can bolster your brain’s neuroplastic abilities, while things like chronic stress can hinder it. If you want a high-performance brain in your 30s, it helps to challenge it in your 20s, but it’s never too late to start.

There is no magical switch that turns on at age 25, or even 32 for that matter. Like your brain, you’re in a decades-long construction project. Stop waiting for the moment you become an adult and start making active choices about how to support this project. Make mistakes, but know that the concrete hasn’t set quite yet.

How can Canada become a global AI powerhouse? By investing in mathematics

Source: The Conversation – Canada – By Deanna Needell, Professor of Mathematics, UBC. Co-Director Programs, Pacific Institute for the Mathematical Sciences, University of British Columbia

This AI-generated illustration is an example of how AI is at our fingertips. But mathematics lies at the heart of AI, and investment in these mathematical foundations will help Canada become a true global AI leader. (Adobe Stock), FAL

Artificial intelligence is everywhere. In fact, each reader of this article could have multiple AI apps operating on the very device displaying this piece. The image at the top of this article is also generated by AI.

Despite this, many mechanisms governing AI behaviour remain poorly understood, even to top AI experts. This leads to an AI race built upon costly scaling, both environmentally and financially, that is also dangerously unreliable.

Progress therefore depends not on escalating this race, but on understanding the principles underpinning AI. Mathematics lies at the heart of AI and investment in these mathematical foundations is the critical key to becoming a true global AI leader.

How AI shapes daily life

AI has rapidly become part of everyday life, not only in talking home devices and fun social media generation, but also in ways so seamless that many people don’t even notice its presence.

It provides the recommendations we see when browsing online and quietly optimizes everything from transit routes to home energy use.

Critical services rely on AI because it’s used in medical diagnosis, banking fraud detection, drug discovery, criminal sentencing, governmental services and health predictions, all areas where inaccurate outputs may have devastating consequences.

Problems, issues

Despite AI’s widespread use, serious and widely documented issues continue to showcase concerns around fairness, reliability and sustainability. Biases embedded in data and models can propagate discriminatory outcomes, from facial detection methods that perform well only on light skin tones to predictive tools that systematically disadvantage underrepresented groups.

Beyond bias: Equity, diversity and inclusion must drive AI implementation in the workplace


These failures continue to be reported and range from racist outputs of ChatGPT and other chatbots to imaging tools that misidentify Barack Obama as white and biased criminal sentencing algorithms.

At the same time, the environmental and financial costs of deploying large-scale AI systems are growing at an extremely rapid pace.

If this trajectory continues, it will not only prove environmentally unsustainable, it will also concentrate access to these powerful AI tools to a few wealthy and influential entities with access to vast capital and massive infrastructure.

Why mathematics?

To address issues with a system, whether it’s fixing a car or ensuring reliability in an AI system, it’s crucial to understand how it works. A mechanic cannot fix or even diagnose why a car isn’t operating correctly without understanding how the engine works.

The “engine” for AI is mathematics. In the 1950s, scientists used ideas from logic and probability to teach computers how to make simple decisions. As technology advanced, so did the math, and tools from optimization, linear algebra, geometry, statistics and other mathematical disciplines became the backbone of what are now modern AI systems.

These methods are certainly modelled after aspects of the human brain, but despite the nomenclature of “neural networks” and “machine learning,” these systems are essentially giant math engines that carry out vast amounts of mathematical operations with parameters that were optimized using massive amounts of data.

This means improving AI is not just about continuously building bigger computers and using more data; it’s about deepening our understanding of the complex math that governs these systems. By recognizing how fundamentally mathematical AI really is, we can improve its fairness, reliability and sustainable scalability as it becomes an even larger part of everyday life.

Canada’s path forward

So what should Canada do next? Invest in the parts of AI that turn power into dependability. That means funding the science that makes AI systems predictable, auditable and efficient, so hospitals, banks, utilities and public agencies can adopt AI with confidence.

This is not a call for bigger servers; it’s a call for better science, where mathematics is the core scientific engine.

Canada already has a national platform to advance this work: the mathematical sciences institutes the (Pacific Institute for the Mathematical Sciences, Fields Institute for Research in Mathematical Sciences, The Centre de recherches mathématiques, Atlantic Association for Research in the Mathematical Sciences, Banff International Research Station connect researchers across provinces and disciplines, convene collaborative programs and link academia with the public sector.

Together with Canada’s AI institutes (Mila, Vector, Amii) and CIFAR, this ecosystem strengthens both foundational and translational AI nationwide.

Canada’s standing in AI was built on decades of foundational research, work that preceded today’s large models and made them possible. Reinforcing that foundation would allow Canada to lead the next stage of AI development: models that are efficient rather than wasteful, transparent rather than opaque and trustworthy rather than brittle. Investing in mathematical research is not only scientifically essential, it is strategically wise and will strengthen national sovereignty.

The payoff is straightforward: AI that costs less to run, fails less often and earns more public trust. Canada can lead here, not by winning a computing power arms race, but by setting the scientific bar for how AI should work when lives, livelihoods and public resources are at stake.

China’s durian craze has turned this tropical fruit into a tool of diplomacy

Source: The Conversation – UK – By Ming Gao, Research Fellow of East Asia Studies, Lund University

Durian is a tropical fruit from south-east Asia that is known for its intensely strong and pungent odour. passkphoto / Shutterstock

Distinctive in taste and famously divisive, durian is not everyone’s choice of fruit. This was certainly the case for some Chinese explorers when they first encountered it during the Ming Dynasty’s early maritime voyages.

One record dates back to 1413, when a translator called Ma Huan travelled to what is now Malaysia on a trip with diplomat and admiral Zheng He. In his travelogue, Ma described durian as a “stinky fruit” that smelled like “rotten beef”.

But fast forward six centuries and this tropical fruit has settled into Chinese daily life. China is now the world’s top importer of durian, accounting for around 95% of global demand. Its imports surged to a record high of nearly US$7 billion (£5.2 billion) in 2024.

Such is the popularity of durian in China that governments across south-east Asia, where most of the world’s durian is produced, are using its export as a tool of political and economic influence.

For years, gifting top-quality durians to Chinese officials has been one way south-east Asian governments have sought to cultivate goodwill. On a visit to Beijing in 1975, for example, former Thai prime minister Kukrit Pramoj gifted 200 durians to Chinese leaders.

More recently, in 2024, Malaysia’s King Ibrahim offered Chinese president Xi Jinping two boxes of premium durians during a state visit. This included the prized Musang King, a variety that is often referred to in China as the “Hermès of durians” – a nod to the exclusive Hermès fashion brand, which is known in China for extreme prestige.

The Chinese premier, Li Qiang, and Malaysia’s prime minister, Anwar Ibrahim, had also been filmed earlier that year sat together tackling a durian with a knife and spoon. The traditional way to eat a durian is to open the fruit and consume the flesh by hand.

However, durian is more than just a symbol of friendship between south-east Asian states and Beijing. China’s massive demand for durians has boosted domestic economic growth across the region, turning some previously poor agricultural areas into sites of prosperity.

According to Eric Chan, a Malaysian durian farmer who was interviewed by the New York Times in 2024, revenue from durian sales to China has transformed his town. Chan said durian farmers there have been able to rebuild their houses from “wood to brick” and can now “afford to send their children overseas for university”.

South-east Asian countries have also used China’s appetite for durian to strengthen their economic relationships with Beijing. Vietnamese durian exports, for instance, have been credited with opening access to the Chinese market for other domestically produced agricultural goods.

And Malaysia’s deputy prime minister, Ahmad Zahid Hamidi, has openly announced that he sees durian exports as a way to secure follow-up Chinese investments. “Durian diplomacy is not just diplomacy – it is durian business,” said Hamidi in November. “We need to work with Chinese businessmen to further develop Musang King plantations in Malaysia, and we should also strengthen downstream industries together.”

Food silk road

For China, the durian trade is part of a broader strategy. Since taking power in 2013, Xi has repeatedly stressed that his country must safeguard its food security. Researchers describe the resulting approach as a “food silk road”, an emerging network of investments and trade agreements designed to diversify China’s food imports across many regions of the world.

Durian from south-east Asian countries is thus one part of a much wider flow. New Zealand exports most of its premium gold kiwifruit to China, with the Chinese market an equally important destination for Chilean cherries. Reports suggest that shipments of Kenyan avocados to China are also increasing.

Donald Trump’s return to the White House in January, and the subsequent global chaos that was unleashed by his sweeping tariff campaign, has enabled China to consolidate these relationships. In the first quarter of 2025, for example, Chinese imports of agricultural products from members of the Association of Southeast Asian Nations reached nearly US$7.5 billion – a 14% increase from the same period in 2024.

According to Chatham House, a UK-based international affairs thinktank, Trump’s erratic policies have led to declining perceptions of the US among south-east Asian officials. This may see countries in the region, including traditional US allies such as the Philippines and Thailand, shift further towards Beijing’s sphere of influence in the near future.

China’s durian boom has delivered rapid growth in south-east Asia, but it has also produced several unintended consequences. The establishment of new durian plantations, for example, has led to deforestation in Indonesia, Laos and Malaysia. This has disrupted local habitats and ecosystems, posing a risk to endangered animal species such as the Malayan tiger.

As the Chinese market continues to grow, south-east Asian countries will also need to prepare for rising foreign control over supply chains and regulatory uncertainty in an unstable global economy. The challenge for these states moving forward will be to capture the benefits of Chinese durian demand while managing the expansion of the industry.
