ChatGPT is in classrooms. How should educators now assess student learning?

Generative artificial intelligence (GenAI) is now a reality in higher education, with students and professors integrating chatbots into teaching, learning and assessment. But this isn’t just a technical shift; it’s reshaping how students and educators learn and evaluate knowledge.

Our recent qualitative study with 28 educators across Canadian universities and colleges — from librarians to engineering professors — suggests that we have entered a watershed moment in education.

We must grapple with the question: What exactly should be assessed when human cognition can be augmented or simulated by an algorithm?

Research about AI and academic integrity

In our review of 15 years of research that engages how AI affects cheating in education, we found that AI is a double-edged sword for schools.

On one hand, AI tools like online translators and text generators have become so advanced that they can write just like humans. This makes it difficult for teachers to detect cheating. Additionally, these tools can sometimes present fake news as facts or repeat unfair social biases, such as racism and sexism, found in the data used to train them.

On the other hand, the studies we reviewed showed AI can be a legitimate assistant that can make learning more inclusive. For instance, AI can provide support for students with disabilities or help those who are learning an additional language.

Because it’s nearly impossible to block every AI tool, schools should not just focus on catching cheaters. Instead, schools and post-secondary institutions can update their policies and provide better training for both students and teachers. This helps everyone learn how to use technology responsibly while maintaining a high standard of academic integrity.

Participants in our study positioned themselves not as enforcers, but as stewards of learning with integrity.

Their focus was on distinguishing between assistance that supports learning and assistance that substitutes for it. They identified three skill areas where assessment boundaries currently fall: prompting, critical thinking and writing.

Prompting: A legitimate and assessable skill

Participants widely viewed prompting — the ability to formulate clear and purposeful instructions for a chatbot — as a skill they could assess. Effective prompting requires students to break down tasks, understand concepts and communicate precisely.

Several noted that unclear prompts often produce poor outputs, forcing students to reflect on what they are really asking.

Prompting was considered ethical only when used transparently, drawing on one’s own foundational knowledge. Without these conditions, educators feared prompting may drift into over-reliance or uncritical use of AI.

Critical thinking

Educators saw strong potential for AI to support assessing critical thinking. Because chatbots can generate text that sounds plausible but may contain errors, omissions or fabrications, students must evaluate accuracy, coherence and credibility. Participants reported using AI-generated summaries or arguments as prompts for critique, asking students to identify weaknesses or misleading claims.

These activities align with a broader need to prepare students for work in a future where assessing algorithmic information will be a routine task. Several educators argued it would be unethical not to teach students how to interrogate AI-generated content.

Writing: Where boundaries tighten

Writing was the most contested domain. Educators distinguished sharply between brainstorming, editing and composition:

• Brainstorming with AI was acceptable when used as a starting point, as long as students expressed their own ideas and did not substitute AI suggestions for their own thinking.

• Editing with AI (for example, grammar correction) was considered acceptable only after students had produced original text and could evaluate whether AI-generated revisions were appropriate. Although some see AI as a legitimate support for linguistic diversity, as well as helping to level the field for those with disabilities or those who speak English as an additional language, others fear a future of language standardization where the unique, authentic voice of the student is smoothed over by an algorithm.

• Having chatbots draft arguments or prose was implicitly rejected. Participants treated the generative phase of writing as a uniquely human cognitive process that needs to be done by students, not machines.

Educators also cautioned that heavy reliance on AI could tempt students to bypass the “productive struggle” inherent in writing, a struggle that is central to developing original thought.

Our research participants recognized that in a hybrid cognitive future, skills related to AI, together with critical thinking are essential skills for students to be ready for the workforce after graduation.

Living in the post-plagiarism era

The idea of co-writing with GenAI brings us into an post-plagiarism era where AI is integrated into into teaching, learning and communication in a way that challenges us to reconsider our assumptions about authorship and originality.

This does not mean that educators no longer care about plagiarism or academic integrity. Honesty will always be important. Rather, in a post-plagiarism context, we consider that humans and AI co-writing and co-creating does not automatically equate to plagiarism.

Today, AI is disrupting education and although we don’t yet have all the answers, it’s certain that AI is here to stay. Teaching students to co-create with AI is part of learning in a post-plagiarism world.

Design for a socially just future

Valid assessment in the age of AI requires clearly delineating which cognitive processes must remain human and which can be legitimately cognitively offloaded. To ensure higher education remains a space for ethical decision-making especially in terms of teaching, learning and assessment, we propose five design principles, based on our research:

1. Explicit expectations: The educator is responsible for making clear if and how GenAI can be used in a particular assignment. Students must know exactly when and how AI is a partner in their work. Ambiguity can lead to unintentional misconduct, as well as a breakdown in the student-educator relationship.

2. Process over product: By evaluating drafts, annotations and reflections, educators can assess the learning process, rather than just the output, or the product.

3. Design assessment tasks that require human judgment: Tasks requiring high-level evaluation, synthesis and critique of localized contexts are areas where human agency is still important.

4. Developing evaluative judgment: Educators must teach students to be critical consumers of GenAI, capable of identifying its limitations and biases.

5. Preserving student voice: Assessments should foreground how students know what they know, rather than what they know.

Preparing students for a hybrid cognitive future

Educators in this study sought ethical, practical ways to integrate GenAI into assessment. They argued that students must understand both the capabilities and the limitations of GenAI, particularly its tendency to generate errors, oversimplifications or misleading summaries.

In this sense, post-plagiarism is not about crisis, but about rethinking what it means to learn and demonstrate knowledge in a world where human cognition routinely interacts with digital systems.

Universities and colleges now face a choice. They can treat AI as a threat to be managed, or they can treat it as a catalyst for strengthening assessment, integrity and learning. The educators in our study favour the latter.

Addressing climate change without the ‘rules-based order’

Source: The Conversation – Canada – By Matthew Hoffmann, Professor of Political Science and Co-Director of Environmental Governance Lab, University of Toronto

At the recent World Economic Forum in Switzerland, Canadian Prime Minister Mark Carney proclaimed “a rupture” in the global “rules-based order” and a turn to great power rivalry.

While its demise is not certain, even the current disruption to global order, largely due to the Donald Trump administration in the United States, promises profound impacts on the global response to climate change. The world is at risk of losing even the insufficient progress made in the last decade.

But it’s unclear what that effect will be. That uncertainty is both a cause for concern and a source of hope. The climate crisis is not slowing, and humanity must figure out how to navigate the disruption.

Unfortunately, much of what we know about how climate politics works has depended on a relatively stable rules-based order. That order, however problematic, provided institutions like the United Nations Framework Convention on Climate Change and the Paris Agreement.

It also established trade rules for energy technology, co-operative agreements on public and private climate finance, and parameters for how civil society and states interact. It structured the opportunities and obstacles for acting on climate change.

Everyone who cares about climate action must now grapple with how climate politics can function in a new world of uncertainty. It won’t be easy.

But, to inject a slight note of hope, I’m not convinced that meeting the climate challenge is harder now. It’s difficult in a different way. Let’s be clear: the rules-based order was not producing effective global co-operation on climate change.

Limited successes of the rules-based order

Canadian Prime Minister Mark Carney’s speech in Davos where he noted the ‘rupture’ in the global rules-based order.(The Journal)

The U.S. has consistently been an obstacle to global climate action. As Carney noted, under the the rules-based order “the strongest would exempt themselves when convenient.” Clearly the U.S. decided from very early on that a stable climate was not a public good it was willing to seriously support.

The U.S. failed to see benefits from climate action that outweighed the perception of costs and has consistently been influenced by status quo, fossil-capital economic interests.

That’s not to say there was no progress under the old rules-based system. At least five sources of progress are worth highlighting:

Possibilities for progress

These sources of past progress on climate action could survive the current disruption and play a role in increasing momentum in the global response to climate change. But uncertainties and questions are more plentiful than answers.

A coalition of the ambitious is clearly what Carney’s speech is seeking to catalyze among middle powers. He was not talking about climate change, but a commitment to climate action could and should be a cornerstone that a new order is built upon. This may even attract one of those competing great powers that he alluded to — China. Will China see climate leadership as a means to enhance its global position?

The political economy of renewable energy has momentum that is at least somewhat insulated from the current disruption. How insulated it remains depends on a number of uncertainties.

What will trade rules and practices look like moving forward? What happens within the fossil-fuel energy sector as the U.S. continues to engage in resource imperialism? How will resource competition and co-operation in the renewables sector (over critical minerals, for example) play out moving forward?

Can experimental efforts be a source of resistance and change within the U.S., especially among individual states? And can they play the same role that they did previously, catalyzing further innovation and public support?

Public support for climate action in this new era will likely vary wildly by country. How will growing dissatisfaction with the status quo play out as it intersects with increasingly severe climate impacts?

This could generate further support for right-wing populism. However, affordability and inequality concerns could also become the foundation for building support for climate action and a just transition.

Does the Paris Agreement survive this? It could become a backbone institution for the coalition of the ambitious. The U.S. is gone, again. Maybe other recalcitrant governments should be sidelined from multilateral climate efforts as well, and those willing to act can proceed.

If full global co-operation around climate change is no longer even a façade of the possible now, then the imperative to bring everyone along at each step in the process may evaporate.

None of the ways forward I’ve laid out here are easy. Even if the positive possibilities materialize, they do not guarantee decarbonization and a just transition that is fast and effective enough to matter; to head off the worst of climate change.

What is clear, though, is that like Carney, climate scholars and activists may need to let the fiction of the global rules-based order go. It was not working either in addressing climate change or enhancing justice. Perhaps its disruption is an opportunity to build better foundations for a just and effective global response to climate change.

Canada should be wary of embracing ‘total national defence’ to ward off an American invasion

Source: The Conversation – Canada – By James Horncastle, Assistant Professor and Edward and Emily McWhinney Professor in International Relations, Simon Fraser University

As the Donald Trump administration in the United States continues to threaten Canadian sovereignty — including a recent suggestion that Alberta could secede from Canada and join the U.S. — Canadians, like many others in the world, finds themselves in a period of extreme uncertainty.

Trump’s continued violations of the rules-based international order means Canada can no longer rely on its partners to the same extent as it has in the past.

The world must, as Prime Minister Mark Carney recently noted, accept the current climate as it is, rather than looking to the past.

Mark Carney’s Davos speech marks a major departure from Canada’s usual approach to the U.S.


To do so, Canada must develop a defence policy that can meet the country’s needs. The Canadian government’s recent budget envisions a significant increase in defence spending over the next several years. The problem Canada faces, however, is one that all middle powers face: an inability to compete with great powers in a conventional war.

The Canadian government must therefore pursue non-conventional means to overcome conventional weakness. Simultaneously, the country must be cognizant of the implications of alternative defence policies. The former Yugoslavia provides a harrowing example.

How to ward off an invasion

The turmoil created by the mercurial American president has caused Canada to examine how it could resist a U.S. invasion in a series of war games. Inevitably, Canada was unable to defeat the U.S. in these exercises, and was forced to rely on unconventional warfare.

One way Canada is considering addressing this issue is by creating a civilian defence force and incorporating “total national defence” principles. This development is not completely new; Canada has been considering it for some time.

Why annexing Canada would destroy the United States


Total national defence in theory

Total national defence is not a new concept. After the Second World War, it became clear to many medium-sized countries that they could not compete with the great powers in a conventional war.

In the 1950s, Yugoslavia spent 22 per cent of its GDP on defence, yet still recognized it was unlikely to defeat a great power in a conventional war. Yugoslavia, and other countries, needed an alternative. Enter total national defence.

The concept of total national defence seeks to mobilize all aspects of society for the war effort. Given the uniqueness of each country, no country’s total national defence system looks the same as the other. What’s important for Canada’s examination, however, is the command-and-control elements of the system.

The biggest vulnerability is the enemy eliminating their command-and-control functions early in the conflict. The U.S., as seen in Iraq in 1991, excels at these types of operations. Russia, while not as effective, attempted to do the same against Ukraine in the early phases of its full-fledged invasion.

For a smaller country to survive such an attack, it needs to ensure that resistance can continue regardless if centralized command is compromised.

Under the theory of total national defence, countries decentralize command and control functions to prevent them being eliminated.

The extent to which countries do so varies. Individual units may operate at the local level without centralized guidance to maintain the struggle against an opponent. In short, even if an opponent succeeds in eliminating the central command of a state, its army and people can continue the struggle.

Canada’s chosen example: Finland

Canada, as it considers implementing such a policy, has looked to Finland for inspiration. Prior to joining NATO, Finland was a relatively small country that could not rely upon allies for defence.

What Canadian officials found in Finland impressed them. Finnish officials have long relied upon extensive joint-use facilities, such as bunkers. It also uses conscription to maintain a strong deterrent.

But Canada and Finland are fundamentally different countries. The persistent threat of Russian invasion has, over time, normalized policies like conscription among the Finnish. Furthermore, and most critically, Finland is, unlike Canada, a unitary state and not a federation.

Canada’s worst-case scenario: Yugoslavia

Much like the former Yugoslavia, Canada is a federation. It has stark regional differences, both in terms of culture and economics.

The divisions in Canada aren’t as entrenched as those in Yugoslavia in the 1980s. Nevertheless, as CSIS recently warned Parliament, the divides are real and outside forces could magnify and exploit them.

U.S. Treasury Secretary Scott Bessent’s recent encouragement of Albertan separatism, and Albertan separatist meetings with Trump officials, are examples of how foreign entities can magnify these divides.

Yugoslavia’s embrace of total national defence relied on the unity of the people to overcome the weaknesses of a decentralized command structure. Without it, not only would the effectiveness of such a defence have been compromised but, more worryingly, separatist forces could have used such decentralized forces for their own purposes.

In fact, separatists did so , using these decentralized defence forces for their own purposes against Yugoslavia. That helped fuel the former country’s conflicts and ultimate dissolution in the 1990s.

Learning from the past

But just because Yugoslavia’s embrace of total national defence and a civilian defence force helped facilitate the breakup of the country doesn’t mean that will happen to Canada. Too often, people assume that history is repetitive.

Instead, the past is an inventory of ideas. Yugoslavia’s embrace of total national defence failed, but Canada can learn lessons about what worked and what will not in a federation, and in doing so improve its own capabilities.

Canada is wise to pursue non-conventional defence strategies. The country, and its defence planners, however, must ensure they’re drawing from the right examples.

Why does this river slice straight through a mountain range? After 150 years, scientists finally know

The western US is a geologists’ dream, home to the Rocky Mountains, the Grand Canyon, active volcanoes and striking sandstone arches. But one landform simply doesn’t make sense.

Rivers normally flow around barriers. The Danube river, for example, flows between the Alps and the Carpathians, twisting and turning to avoid the mountains.

But in north-western Colorado, one river does the opposite.

The intimidatingly named Gates of Lodore marks the entrance to the 700-metre deep Canyon of Lodore that slices straight through the Uinta Mountains as if the range wasn’t there at all. It was created by the Green River, the largest tributary of the Colorado River (of Grand Canyon fame).

For more than 150 years, geologists have debated why the Green River chose such an unusual path, creating a spectacular canyon in the process.

In 1876, John Wesley Powell, a legendary explorer and geologist contemplated this question. Powell hypothesised that the river didn’t cut through the mountain, but instead flowed over this route before the range existed. The river must have simply maintained its course as the mountains grew, carving the canyon in the process.

Unfortunately, geological evidence shows this cannot be the case. The Uinta Mountains formed around 50 million years ago, but we know that the Green River has only been following this route for less than 8 million years. As a result, geologists have been forced to seek alternative explanations.

And it seems the answer lies far below the surface.

Drip drip

Colleagues and I have found evidence for a process in which part of the Earth’s crust becomes so dense that it begins to sink into the mantle beneath it. This phenomenon, known as a “lithospheric drip”, occurs deep in the Earth, but can have profound effects on the surface.

Drips often form beneath mountain ranges. The sheer weight of the mountains raise temperatures and pressures at the base of the crust, causing dense minerals to form. As these minerals accumulate, the lower crust can become heavier than the mantle it “floats” on. At this point, the crust begins to detach, or “drip”, into the mantle.

Diagram of lithospheric drip
Dripping (left) then rebounding (right).
Smith et al (2026)

At the surface, this causes two things. Initially as the drip forms, it pulls the crust down, lowering the height of the mountain range above. Then as the drip detaches, the crust springs or rebounds back. The whole process is like pulling a trampoline down and then letting it go again.

For the Green River, this temporary lowering of the Uinta Mountains appears to have removed a critical barrier. The river was able to cross the range during this low period, and then, as the range rebounded, it carved the Canyon of Lodore as it continued on its new course.

A geological bullseye

Our evidence for the lithospheric drip comes from the river networks around the Uinta Mountains. Rivers record a record of past changes to landscapes, which geomorphologists can use to assess how the elevation of a mountain range may have changed in the distant past. The rivers around the Uintas show that the range had recently (in geological terms) undergone a phase of renewed uplift.

By modelling these river networks, we were able to map out the uplift. The result was striking: a bullseye-shaped pattern, with the greatest uplift at the centre of the mountain range, with things decreasing further from the centre. Around the world, this same pattern represents the telltale sign of a lithospheric drip. Similar signals have been identified in places such as the Central Anatolian Plateau in Turkey, as well as closer to the Uinta Mountains on the Colorado Plateau or the Sierra Nevada of California.

To test whether such a process was occurring beneath the Uintas, we turned to seismic tomography. This technique is similar to a medical CT (computerised tomography) scan: instead of using X-rays, geophysicists analyse seismic waves from earthquakes to infer the structure of the deep earth.

Existing seismic imaging reveals a cold, round anomaly more than a hundred miles below the surface of the Uintas. We interpreted this huge feature, some 30-60 miles across, as our broken-off section of the drip.

By estimating the velocity of the sinking drip, we calculated it had detached between 2 and 5 million years ago. This timing matches the uplift inferred from nearby rivers and, crucially, perfectly matches separate geological estimates for when the Green River crossed the Uinta Mountains and joined the Colorado River.

Taken together, these different bits of evidence point towards a lithospheric drip being the trigger that allowed the Green River to flow over the Uintas, resolving a 150-year-old debate.

A pivotal moment in the history of North America

When the Green River carved through the Uinta Mountains, it fundamentally changed the landscape of North America. Rather than flowing eastwards into the Mississippi, it became a tributary of the Colorado River, and its waters were redirected to the Pacific.

This rerouting altered the continental divide, the line that divides North American river systems that flow into the Atlantic from those that flow into the Pacific. In doing so, it created new boundaries and connections for wildlife and ecosystems.

The story of the Green River shows that processes deep within the Earth can have profound impacts for life on the surface. Over geological timescales, movements of country-sized lumps of minerals many miles below the surface can reshape mountains, redirect rivers and ultimately influence life itself.

Men rule the Grammys as women see hard drop in wins at 2026 awards

Source: The Conversation – UK – By Luba Kassova, PhD Candidate, Researcher and Journalist, University of Westminster

In her acceptance speech for best pop vocal album at the 68th Grammy Awards ceremony last night, Lady Gaga shone a light on the challenges that women face in studios. “It can be hard,” she said. “So, I urge you to always listen to yourself and … fight for your songs, fight for yourself as a producer. Make sure that you are heard, loudly,” she continued, placing the onus on women to take control of the fight for equality in music.

Many well-established and new female superstars were indeed heard loudly last night in the broadcast, which clearly made sure to display gender balance in front of the camera. However, when it comes to awards, nominations and the wider industry the picture is much different.

Working with my business partner, strategist Richard Addy, I looked at gender representation across all 95 of this year’s Grammy categories. Our analysis reveals that women and female bands sustained a dramatic fall in winners compared to last year. They received less than a quarter of all Grammys (23%), a 14 percentage point drop from last year’s high of 37% and the lowest level since 2022.

This fall has been partly a reflection of women’s declining recognition as Grammy nominees. Women’s representation peaked at under a third (28%) of all nominations last year, and this year just one in four nominations (24%) were given to women.

Despite Lady Gaga’s encouraging words for women to own their music as producers, their fight for a seat at the producers’ table is yet to yield results. Since its introduction 51 years ago, no woman has ever won the coveted Grammy for producer of the year, non-classical. Last year, Alissia became only the tenth woman to even earn a nomination in the category but lost out to Daniel Nigro. This year, all five nominees were male.

Addy and I have previously conducted a year-long data-led investigation of over 9,700 Grammy nominations and over 2,200 wins between 2017, revealing that it takes a village of men to raise a superstar, female or male. The winners of record, album and song of the year – three of the four most coveted Grammy awards – typically come on stage to collect their trophy alone.

In reality, however, they share their award with numerous producers, engineers and mixers, who are overwhelmingly male. So music icons like Beyoncé or Taylor Swift collecting their individual awards masks the male dominated structures behind these wins. For example, Bad Bunny, this year’s album of the year winner, has received it alongside 12 male producers, songwriters and technicians who were not on stage with him.

Despite women’s consistently high visibility at the Recording Academy nominee announcements and broadcasts over the year, their recognition across the Grammys has remained peripheral compared to men’s. Since 2017, 76% of nominations and wins across all categories have been awarded to men. By contrast, women have been nominated for and won only one in five Grammys in the same period.

Research consistently shows that the reasons women remain marginalised in the Grammys and in music more generally, are deeply structural and multifaceted.

Although the Recording Academy’s mission is to advance a strong culture of diversity, inclusion, belonging and respect in the music industry, women remain marginalised as Recording Academy members. The proportion of Grammy voting members who are women has grown from 21% (2018) to 28% (2024). But this growth rate will only deliver gender parity in 2051.

This slow growth is likely linked to 69% of voting members being songwriters, composers, producers and engineers, roles in which women’s marginalisation has repeatedly been reported to be highest. For example, the latest Inclusion In the Recording Studio report from the Recording Academy revealed the overall ratio of men to women songwriters in Billboard Hot 100 year-end charts across 13 years is 6.2 to 1.

Our assessment of 67 academic papers and reports in our report, The Missing Voices of Women in Music and Music News, revealed that gender discrimination, sexual harassment and sexual violence consistently hinder women’s success in music, as do pay gaps, women’s cultural exclusion from the “boys club” and limited discovery and promotional opportunities. According to Be The Change: Gender equity in music, a 2024 report from consultancy Midia based on research conducted across 133 countries 60% of women in the music industry have experienced sexual harassment while one in five women have survived sexual assault.

The evidence points to a reality in which no matter women’s talent or determination to succeed, they will only be able to do so if the music industry changes. Until then, we are unlikely to see women achieving recognition parity at the Grammys or any other music awards.

Crime is no longer just a local issue – that’s why a national police force is needed

Source: The Conversation – UK – By Estelle Marks, Assistant Professor in Criminology, University of Sussex; King’s College London

Modern crime transcends place and space. From burglary to fraud, crime increasingly crosses local, national and digital borders. England and Wales’ geographically restricted police forces are not well equipped to respond.

This is why the home secretary, Shabana Mahmood, has announced a significant restructuring of the policing system. The proposals include establishing a National Police Service and merging existing local forces areas into larger regional ones.

Currently, England and Wales have 43 local police forces. Each has different organisational structures and levels of expertise in specific areas of crime. Police intelligence databases and digital capabilities vary, which can silo local forces and result in blind spots.

Most of the country’s specialist policing resources are situated in London’s Metropolitan police and the National Crime Agency. This uneven distribution of resources leaves local forces reliant on each other as specialist needs arise.

Even crime we think of as “local” can exploit force boundaries. Burglars and car thieves may cross local force borders to avoid multiple crimes being linked by police. This problem is more evident in serious crimes like weapons or drug trafficking and modern slavery. Organised crime groups move products and people around the country, and often across international borders.

Much modern crime is also placeless or transnational. Technology-enabled crime, phishing and other scams, and image-based abuse can involve victims and perpetrators in multiple locations, both in the UK and abroad. Fraud is currently the most prevalent crime affecting people in the UK.

The problem for British policing is therefore not simply a question of efficiency, but one of fit. The current structure of policing does not match the structure of crime.

The government’s proposals will centralise existing specialist policing capabilities into a single organisation, better equipped to respond to cross-border crime. This, the home secretary argues, will reduce intelligence blind spots, allow police to share data nationally, and save money.

A National Police Service will also provide stronger leadership and accountability. The NPS will be headed by a chief constable who will be Britain’s most senior officer. The proposals have been welcomed by current police leadership organisations including the National Police Chiefs’ Council, the College of Policing and the independent Police Foundation.

A national approach

To understand the benefits of this approach, we can look at another area where the UK has already nationalised its efforts – extradition policing.

A National Extradition Unit was established ahead of Brexit to bring frontline extradition policing into one team. Before this, responsibility was dispersed across all local forces, with the National Crime Agency coordinating and linking UK policing to partners overseas.

The UK receives more extradition requests – to send criminals to other countries – than it issues. The bulk of extradition work involves tracking down fugitives wanted by foreign states, bringing them before the courts and arranging for their removal from the UK. Although larger forces sometimes had dedicated teams, for many local forces this work competed with other duties and force priorities.

Crime is crossing international and digital borders every day.

If a fugitive could not be located in one local area, the warrant would be returned to the NCA to reallocate the case to another force, wasting time and money. Once a fugitive was arrested, local forces would need to transport them to London, where extradition courts are located.

Once extradition was agreed by the court, these forces would have to travel again to meet international police officers at airports (often in London) to hand the individual over into foreign custody. All of this cost significant officer time and resources, often at very short notice.

The National Extradition Unit now sits within the newly formed Joint International Crime Centre, which offers a one-stop-shop service to UK policing and international partners.

This centralisation has reduced inefficiency and strengthened international partnerships, which is crucial in the face of growing transnational crime. There is also potential to centralise more international capabilities, such as criminal evidence exchange.

The formation of a National Police Service aims to replicate these benefits across policing: driving down costs and inefficiency, increasing effectiveness and improving governance. If delivered, it should improve the UK response to national and international cross-border crime.

Unresolved issues

Reform of British policing is long overdue – the last structural reforms were in 1964. But the movement to a national structure naturally raises questions about the future of neighbourhood policing. The number of community support officers has fallen 40% since 2010, and the public is disappointed with police responses to crimes like shoplifting, which predominantly affect local areas.

There is also the question of the relationship between the national and regional levels, which is not clearly spelt out in the proposals. Another unresolved issue is the status of the National Crime Agency – currently the UK’s national law enforcement agency that investigates serious and organised crime – as it is absorbed into a future National Police Service.

Of more concern are proposals to expand the home secretary’s powers to dismiss chief constables and to set centralised performance targets. This centralisation of power into government potentially threatens operational independence, a foundational principle of British policing.

Why the home secretary can’t fire a police chief who has done wrong – it’s key to the integrity of British policing


The imposition of performance targets under previous governments has tended to focus police on what is measured, not always on what matters most: maintaining public trust while effectively responding to serious crime. It is important that the implementation of these reforms guards against unintended consequences that undermine those capabilities.

A centralised system could better equip police to deal with modern, borderless crime. Yet this must be balanced against the need for local accountability and operational independence.

The success of a National Police Service will depend on how it is designed and governed. As the proposals move through consultation and scrutiny, the challenge for the government will be to modernise policing without undermining the principle of public trust on which it ultimately depends.

Stroke survivors can counterintuitively improve recovery by strengthening their stronger arm – new research

Stroke survivors often face substantial and long-lasting problems with their arms. Both arms often decline together: When one arm is more severely affected by the stroke, the other becomes more difficult to use as well. Compared with a healthy person’s dominant hand, a stroke survivor may take up to three times longer to complete everyday tasks using their less-impaired arm.

This creates a frustrating reality. People with severe impairment in one arm must rely almost entirely on their other arm for daily activities, such as eating, dressing and household tasks. When that “good” arm works slowly or awkwardly, even simple activities become tiring and discouraging, and some people may begin to avoid them altogether.

But that good arm can be strengthened. In our newly published research in the journal JAMA Neurology, we found that training the less-impaired arm in people living with chronic stroke can improve everyday hand function, in some cases even better than focusing only on the most impaired arm.

What is a stroke?

A stroke occurs when the flow of oxygen-carrying blood to part of the brain is interrupted by a blockage in a blood vessel or by bleeding. Without oxygen, brain cells begin to die.

Because each side of the brain mainly controls the opposite side of the body, a stroke often causes movement problems on the side of the body opposite the brain injury. For this reason, stroke rehabilitation has traditionally focused on restoring movement in the most impaired arm.

If someone’s face is drooping, their arm is weak or they’re having difficulty with speech, it’s time to call 911.

However, research over the past few decades has shown that both sides of the brain contribute to controlling movements for both arms, although they play different roles. As a result, damage to one side of the brain can affect movement on both sides of the body.

As expected, the arm opposite the brain injury often has major problems with weakness, stiffness and voluntary control, limiting its use for reaching, grasping and manipulating objects. But the other arm, usually thought to be unaffected from the stroke, is frequently not normal either. Many stroke survivors experience reduced strength, slower movements and poorer coordination in the less-impaired arm.

Training the less-impaired arm

As neuroscientists who study how the brain controls movement after stroke, these findings led us to a simple question: Could training the less-impaired arm help it work better?

In a clinical trial of over 50 patients, we studied people living with chronic stroke who had severe impairments in one arm, making it unusable for everyday tasks. These individuals depended almost entirely on their less-impaired arm to manage daily life.

Participants were randomly assigned to one of two rehabilitation groups: one that trained their most-impaired arm, and one that trained their less-impaired arm. Both received five weeks of therapy that involved challenging, goal-directed hand movements, including virtual reality tasks designed to improve coordination and timing.

Compared to those who trained their most-impaired arm, we found that participants who conditioned their less-impaired arm became faster and more efficient at everyday hand tasks, such as picking up small objects or lifting a cup. These improvements remained six months after training ended.

We believe the lasting benefit of training the less-impaired arm may come from a simple feedback loop: When their arm works better, people naturally use it more, and that extra practice in daily life helps lock in those gains.

Strengthening what remains

Stroke rehabilitation has long focused on the arm that is most visibly impaired. But for many people, full function in that arm never returns. They adapt and rely on their less-impaired arm to get through the day.

“Less-impaired,” however, does not mean unaffected. When this arm becomes the sole tool for daily activities, even mild problems can have major consequences for independence and quality of life. Improving how well this arm works could make everyday tasks faster, easier and less exhausting, even years after a stroke.

Future work will focus on how best to combine training of the less-impaired arm with standard therapy for the more-impaired arm, and how these approaches translate into everyday life at home.

For many survivors, recovery may not mean restoring what was lost but strengthening what remains.

Un robot, un cerveau, une découverte : démystifier l’équilibre debout

Source: The Conversation – in French – By Jean-Sébastien Blouin, Professor, School of Kinesiology, University of British Columbia

Imaginez-vous au volant d’une voiture dont la direction ne réagit pas instantanément et dont le GPS indique toujours où vous étiez une seconde plus tôt. Pour conduire un tel véhicule, vous devriez constamment déduire comment manœuvrer le volant à partir d’informations qui ne sont pas à jour.

C’est exactement ce que fait le cerveau chaque fois que l’on bouge : les signaux sensoriels atteignent le cerveau quelques dizaines de millisecondes après un événement, et les commandes motrices mettent un temps similaire pour arriver aux muscles, qui ont besoin de temps pour générer de la force. En d’autres termes, le cerveau travaille toujours avec des « informations anciennes » et doit prédire le résultat de chaque action.

Cette capacité prédictive est particulièrement impressionnante lorsque nous nous tenons debout, car elle permet de maintenir l’équilibre d’un corps grand et lourd sur deux petits pieds.

Les défis de l’équilibre

Les scientifiques savent depuis longtemps que le temps de réponse neuronale rend complexe le contrôle de l’équilibre. Même chez les jeunes adultes en bonne santé, il faut environ un sixième de seconde pour que les informations provenant des pieds, des muscles et des oreilles internes atteignent le cerveau, puis pour qu’un signal correctif soit envoyé aux muscles. Les modèles physiques simples considèrent le corps comme une masse qui s’équilibre autour des chevilles et prédisent qu’il devient impossible de rester debout si la transmission des informations neuronales et le temps de réponse sont trop longs.

Les propriétés physiques de notre corps influencent notre façon de bouger. Tout comme un gros camion se conduit plus lourdement qu’une petite voiture, une personne grande ou lourde qui se tient debout a une plus grande résistance au mouvement et ressent moins les poussées externes ou les secousses soudaines.

Pour vérifier si le cerveau traite les signaux décalés temporellement de la même manière qu’il traite les changements dans la mécanique corporelle, une équipe de l’Université de Colombie-Britannique et du Centre médical universitaire Erasmus, aux Pays-Bas, a construit un robot de simulation corporelle grandeur nature.

Les participants, debout sur deux plateformes de force, sont attachés à un cadre rembourré. Des moteurs déplacent le cadre en fonction des forces qu’ils génèrent, ce qui fait que l’ensemble du système se comporte comme leur vrai corps qui oscille sous l’effet de la gravité.

Le robot peut modifier la mécanique corporelle simulée en temps réel : il peut faire sentir la personne plus légère ou plus lourde, ajouter ou retirer de l’énergie à ses mouvements ou insérer un délai entre son effort et le mouvement ressenti, imitant ainsi le décalage sensorimoteur du cerveau.

Trois expériences

À l’aide de cet outil, les scientifiques ont voulu déterminer si le cerveau traitait le temps (le délai) et l’espace (la dynamique corporelle) de manière indépendante. Pour ce faire, ils ont mené trois expériences :

1. Les changements dans la dynamique corporelle et les délais modifient l’équilibre de manière similaire. Les participants étaient debout, et le robot insérait un décalage de 0,2 seconde entre leurs commandes et le mouvement résultant. Cette micropause provoquait une importante oscillation et a amené de nombreux participants à la limite virtuelle de la chute. De même, l’oscillation augmentait quand le robot changeait le corps pour le rendre plus léger ou ajoutait de l’énergie au mouvement, un peu comme lorsqu’un coup de vent pousse une personne.

2. Les délais temporels sont perçus comme une modification de la mécanique corporelle. Une fois le retard désactivé, les participants ajustaient les propriétés mécaniques de leur corps jusqu’à ce que leur sensation corresponde à la sensation de délai qu’ils venaient de ressentir. Ils optaient alors pour un corps plus léger ou un réglage qui ajoutait de l’énergie. Lorsqu’on leur demandait de rendre la condition d’équilibre en présence d’un délai « naturelle », ils choisissaient un corps plus lourd ou un réglage qui dispersait l’énergie. Ainsi, modifier les propriétés mécaniques du corps permet de recréer ou d’annuler la sensation de signaux différés dans le temps.

3. Améliorer l’équilibre en présence d’un délai. Des personnes qui n’avaient jamais utilisé le robot furent soumises à un retard de 0,2 seconde entre leurs commandes motrices et le mouvement résultant. Lorsque leur corps étaient plus lourd ou dissipait l’énergie du mouvement, leur équilibre s’améliorait instantanément – aucun entraînement ou adaptation requis. Les oscillations étaient réduites de 80 % et la plupart des participants n’atteignaient plus la limite virtuelle de chute.

Le temps et l’espace

Ces trois expériences permettent de tirer une conclusion : le cerveau ne stocke pas de solutions distinctes pour des « informations décalées » et un « corps instable ». Au contraire, il maintient un modèle interne unifié qui fusionne le temps et l’espace en une seule représentation du mouvement.

Lorsque le retour sensoriel a du retard et que le corps est instable, ajouter de la lourdeur ou dissiper l’énergie du mouvement rétablit l’équilibre. À l’inverse, alléger le corps ou ajouter de l’énergie reproduit l’instabilité causée par les retards neuronaux. Dans les deux cas, une représentation unifiée de l’équilibre permet de demeurer en équilibre debout.

Ces découvertes sont plus que de simples curiosités scientifiques. Avec l’âge ou en cas de maladies endommageant les nerfs longs, les signaux voyagent plus lentement et sont davantage perturbés, ce qui provoque des troubles de l’équilibre et augmente le risque de chutes. Selon l’Organisation mondiale de la santé, une personne âgée sur trois fait une chute une fois par an, ce qui en fait la principale cause d’hospitalisation pour blessure et engendre un coût de plusieurs milliards de dollars pour les systèmes de santé.

Le robot de simulation corporelle offre une nouvelle perspective sur ce problème : des appareils fonctionnels et des exosquelettes portables qui fournissent juste assez de résistance au moment où une personne commence à vaciller peuvent contrebalancer les effets déstabilisants des ralentissements neuronaux.

Ils soulèvent également une question plus large : la taille des animaux et les mécanismes compensant les retards neuronaux ont-ils évolué pour améliorer leur survie ?

La prochaine fois que vous vous pencherez au-dessus d’un évier ou que vous aurez une discussion sur le pas de la porte, rappelez-vous que votre cerveau jongle discrètement avec le temps et les représentations corporelles en arrière-plan. Le plus étonnant est peut-être le fait que l’on ne remarque jamais ce travail.

« Aime-moi ! » ou comment les entreprises peuvent générer de l’engagement entre elles

Source: The Conversation – in French – By Benoit Bourguignon, Professeur de marketing, Université du Québec à Montréal (UQAM)

Une publication de McDonald’s peut générer 17 000 réactions. Pour une entreprise qui vend à d’autres entreprises, en obtenir une trentaine relève déjà de la performance. Sur les réseaux sociaux, le marketing Business-to-Business (B2B) semble condamné à un faible engagement. Nos recherches montrent pourtant que ce désavantage n’est pas une fatalité.


Tout le monde veut être aimé ; les entreprises aussi. Et ce besoin d’amour se manifeste également sur les réseaux sociaux où chaque publication cherche à attirer un maximum de « J’aime ». Or, les publications B2B suscitent beaucoup moins d’engagements sur les réseaux sociaux que celles des marques destinées aux consommateurs individuels (B2C). Dans notre échantillon, une publication d’entreprise reçoit en moyenne 29 réactions, loin des milliers générées par certaines campagnes B2C.

Depuis deux ans, notre équipe de recherche s’est penchée sur ce qui favorise les réactions positives sur les publications des entreprises qui vendent à d’autres entreprises — par exemple, une société qui fournit de la farine à un boulanger, un logiciel de comptabilité à une PME, ou des composants électroniques à un fabricant.

Nous avons mené plusieurs études, dont deux se dégagent particulièrement : l’une sur le rôle de la narration, l’autre sur l’effet des émotions exprimées dans les publications diffusées sur les réseaux sociaux.

Carburer aux histoires

« Laissez-moi vous raconter ce qui m’est arrivé hier ! »

Avez-vous déjà remarqué que cette simple phrase suscite immédiatement l’attention de vos interlocuteurs ? L’être humain carbure aux histoires, que ce soit dans les livres, les films ou les réseaux sociaux. Les organisations utilisent elles aussi la narration pour capter l’intérêt des consommateurs, mais aussi d’autres entreprises qui sont leurs clientes. Quand on raconte une histoire, on retrouve généralement des personnages, des séquences d’événements et un lieu où se déroulent ces actions.

Dans une étude, nous avons cherché à retrouver ces éléments de la narration dans 85 075 publications de 439 entreprises B2B afin de déterminer s’ils favorisaient l’engagement. Comme mesure de l’engagement, nous avons additionné le nombre de « J’aime », de commentaires et de partages. Nous avons utilisé le traitement automatique des langues pour analyser près de 4,3 millions de mots contenus dans ces publications.

Par exemple, une entreprise a publié ceci en anglais : « Chaque mois de juin, nous tenons le Mois du leadership en matière de sécurité afin de recentrer nos efforts et de nous réengager envers notre objectif de zéro incident de sécurité. Découvrez comment (noms des 4 employés) font de la sécurité une obligation ».

La publication se poursuit avec le témoignage de ces quatre employés. En présentant ces personnes racontant une histoire dans leur entreprise, on retrouvait des éléments de narration qui ont contribué à susciter 52 réactions, 2 commentaires et 3 republications, ce qui représente un niveau d’engagement important pour une entreprise qui ne vend pas aux consommateurs.

On sait depuis longtemps que la narration influence positivement l’image des marques auprès des consommateurs. Nos résultats démontrent que la narration peut aussi avoir une influence positive sur l’engagement envers des publications de compagnies de B2B. Pourtant, elle reste encore peu utilisée en B2B, notamment sur les médias sociaux, alors même qu’elle permet de rendre les communications plus authentiques, de mieux utiliser les ressources et de créer des relations plus fortes.

Générer une réaction

Une autre stratégie utilisée par les marketeurs pour susciter de l’intérêt, que ce soit sur TikTok, Instagram ou Facebook, est de créer du contenu qui génère une réaction émotionnelle. Parmi les 27 émotions que nous avons étudiées, 24 ont une influence significative sur l’engagement, dont la surprise, comme avec l’anecdote relatée par cette publication qui a reçu 33 réactions, soit plus que la moyenne : « Aujourd’hui, c’est la Journée mondiale des sols (#WorldSoilDay). Fait surprenant : une cuillère à soupe de sol contient plus d’organismes qu’il n’y a de personnes sur Terre ».

On connaît, depuis des décennies, l’importance de susciter des émotions chez les consommateurs pour qu’ils s’intéressent à un produit ou à un service, même s’ils refusent parfois de l’admettre. À l’inverse, les décisions d’achat en entreprise sont souvent perçues comme rationnelles et uniquement guidées par des chiffres.

Or, les acheteurs professionnels en B2B, comme les consommateurs, sont tout aussi influencés par leurs émotions lorsqu’ils sont soumis à des propositions commerciales, car derrière chaque organisation il y a des personnes. Et ces personnes, comme tout le monde, éprouvent des émotions vis-à-vis d’une marque ou d’une présentation d’un produit ou d’un service.

Les décisions B2B ne reposent donc pas seulement sur des chiffriers Excel et des critères techniques : elles sont aussi influencées par des émotions, des perceptions et des histoires qui rendent une option plus rassurante, plus crédible ou plus désirable que les autres.

L’impact concret de la narration et des émotions

Il fallait maintenant étudier si cela se traduisait par un plus grand engagement sur les réseaux sociaux. Pour mesurer l’effet des émotions sur l’engagement, nous avons analysé 65 027 publications sur Facebook de 439 entreprises canadiennes de B2B. Afin de classer les publications selon les émotions, nous avons appliqué des méthodes de traitement automatique des langues à l’aide d’un jeu de données public, et mesuré l’engagement de la même façon que dans l’étude précédente.

Il en ressort que des émotions positives, comme la joie, la fierté et l’admiration ont un effet positif sur l’engagement. Une seule émotion négative, le chagrin, génère de l’engagement, probablement par empathie, comme ces nombreuses publications d’entreprise soulignant le décès de la reine Elizabeth, qui ont eu un niveau d’engagement supérieur.

Par exemple, une entreprise d’équipements en cuir pour chevaux a publié : « Aujourd’hui, le monde a perdu une véritable cavalière. Reposez en paix, reine Elizabeth II. » Cette publication a reçu 52 réactions, et 2 commentaires et a été partagée 13 fois. Les publications neutres, c’est-à-dire sans présence manifeste d’émotion, ont plutôt un effet négatif sur l’engagement.

On pense souvent que les algorithmes décident de tout, mais l’engagement naît souvent d’une émotion. Une histoire qui étonne, qui émeut ou qui fait rire peut suffire à susciter le désir de réagir. Et c’est sans doute la seule stratégie qui résiste au temps lorsqu’il s’agit de se faire aimer.

Quand les animaux de compagnie dévorent la biodiversité : un vide juridique dans l’Union européenne

Source: The Conversation – in French – By Miguel Ángel Gómez-Serrano, Assistant lecturer, Universitat de València

Les textes européens qui encadrent le bien-être animal le circonscrivent aux espèces domestiques. digitalienspb/Shutterstock

À travers ses grands textes, l’Union européenne défend la biodiversité d’un côté et le bien-être de nos animaux domestiques de l’autre. Mais que dit-elle quand nos chats et chiens attentent à la faune sauvage ? Pas grand-chose pour l’instant…


Près de 44 % des ménages de l’Union européenne possèdent au moins un animal de compagnie, dont plus de 90 % sont des chiens ou des chats.

La place des animaux de compagnie dans nos vies n’a cessé de croître au cours des dernières décennies, mais elle s’est fortement accélérée à partir de la pandémie de Covid-19. Plus précisément, on estime que la population européenne d’animaux de compagnie a augmenté de 11 % en 2022, pour atteindre 340 millions, principalement des chats (127 millions) et des chiens (104 millions).

À mesure que les foyers adoptent chiens et chats, l’intérêt pour leur bien-être ne cesse de croître. Dans le même temps, le déclin des populations d’animaux sauvages alerte la société sur la nécessité de protéger la biodiversité.

Mais cette convergence ne va pas toujours de soi. S’il existe un certain chevauchement entre les objectifs du bien-être animal et ceux de la conservation de la faune sauvage, un biais apparaît clairement dans la hiérarchisation des priorités entre animaux de compagnie et animaux sauvages, en particulier lorsque ces deux groupes interagissent.

Miguel Ángel Gómez-Serrano

Une étude récente identifie les ressorts du conflit entre défenseurs du bien-être des animaux de compagnie et partisans de la conservation de la nature. Ce travail analyse les leviers juridiques, dans le cadre de l’Union européenne, permettant de réduire l’impact des animaux de compagnie sur les animaux sauvages.

Deux cadres juridiques difficilement conciliables

L’Union européenne dispose actuellement d’une législation environnementale solide, dans laquelle les directives « Oiseaux » et « Habitats » ont joué un rôle clé dans la protection de la faune sauvage. En revanche, la législation relative au bien-être animal – en particulier celle concernant les animaux de compagnie – est beaucoup plus récente et reste encore émergente.

En toute logique, le bien-être animal a été associé exclusivement aux espèces domestiques, tandis que les espèces sauvages relèvent du droit de l’environnement.

Mais ce déséquilibre a engendré un important vide juridique : que se passe-t-il lorsque des animaux de compagnie causent des dommages à la faune sauvage ?

Des animaux de compagnie devenus sauvages

Parmi les impacts les plus importants des animaux de compagnie sur la faune sauvage figurent ceux liés aux individus retournés à l’état sauvage. Les animaux abandonnés ou échappés peuvent former des populations autosuffisantes dans la nature, avec de graves conséquences pour les espèces autochtones.

Les perroquets échappés des foyers en sont un bon exemple. Des espèces comme la perruche à collier ou la conure veuve ont établi des colonies dans de nombreuses villes européennes. Au-delà de la question de savoir s’il faut les considérer comme des espèces invasives, leur gestion constitue un conflit socio-environnemental complexe.

Certains travaux scientifiques suggèrent qu’elles entrent en compétition avec les espèces locales pour les sites de nidification et les ressources, mais ce sont des animaux charismatiques et appréciés par le public, si bien que leur régulation suscite de vives controverses sociales.

Cependant, si un animal de compagnie concentre particulièrement les préoccupations lorsqu’il retourne à l’état sauvage, c’est bien le chat domestique. Il est considéré comme l’un des prédateurs invasifs les plus nocifs au monde, responsables d’environ 25 % des extinctions contemporaines de reptiles, d’oiseaux et de mammifères à l’échelle mondiale.

Malgré ces preuves, il existe encore en Europe une forte réticence à reconnaître les chats retournés à l’état sauvage (ou chats harets) comme des espèces invasives, ce qui limite les options juridiques pour gérer leur impact.

Animaux de compagnie qui errent librement hors de leur domicile

De nombreux animaux de compagnie passent une partie de leur temps à l’extérieur sans surveillance. Pour les chiens, les impacts concernent principalement la prédation sur la faune sauvage et la transmission de maladies.

Les chats, qui errent plus librement hors de leur domicile, pratiquent également la prédation, même lorsqu’ils sont bien nourris, affectant particulièrement les oiseaux et les petits vertébrés dans les environnements urbains et périurbains.

Un cas particulier concerne les colonies félines. Le contrôle des populations de chats errants relève généralement des États membres de l’UE, ce qui entraîne des approches très variées, allant de la mise à l’écart des animaux aux programmes de capture, stérilisation et retour (méthode CSR).

Bien qu’il s’agisse d’une méthode socialement acceptée, les preuves scientifiques montrent que, dans la majorité des cas, elle n’est pas efficace pour réduire la population de chats ni pour limiter à court terme leur impact sur la faune sauvage.

Promener des animaux de compagnie dans la nature

Promener son chien dans la nature est devenu une des activités de loisirs particulièrement courante, en atteste notamment, dans les zones concernées, la popularité croissante des plages pour chiens. Ce type de gestion est probablement bénéfique pour la santé des animaux et de leurs propriétaires, mais pas pour la faune sauvage.

Sur les plages naturelles, par exemple, les chiens peuvent avoir un impact grave sur les oiseaux nichant au sol, comme les gravelots à collier interrompu. Même en l’absence de prédation directe, la simple présence d’un chien peut amener les oiseaux à abandonner leurs nids ou à réduire le temps d’incubation, avec des effets négatifs sur le succès reproducteur.

Réconcilier le bien-être animal et la conservation

À mesure que la biodiversité diminue et que les populations d’animaux de compagnie augmentent dans les foyers européens, le conflit entre la conservation de la faune sauvage et la défense du bien-être animal s’intensifie. Il devient donc urgent de réconcilier ces perspectives divergentes et d’harmoniser leurs cadres juridiques respectifs.

L’Union européenne dispose de marges de manœuvre juridique pour agir. Les directives environnementales obligent déjà les États membres à prévenir les dommages aux espèces protégées, ce qui pourrait se traduire par des restrictions plus claires concernant la liberté de déplacement des animaux de compagnie, en particulier dans les espaces naturels protégés.

Parallèlement, l’élaboration d’une nouvelle législation sur le bien-être animal constitue une occasion de renforcer la responsabilité des propriétaires tout en réduisant l’impact de la liberté de déplacement et en prévenant l’abandon ou le retour à l’état sauvage.

Il est nécessaire que les autorités s’attellent à la régulation de l’impact des animaux de compagnie et que leurs propriétaires s’engagent activement à les limiter. Ce n’est qu’ainsi que nous éviterons d’atteindre le point de non-retour où les seuls animaux que nous observerons lors de nos promenades dans la nature seront nos propres animaux de compagnie.
