It also reported recurring earnings before interest, taxes, depreciation and amortization (EBITDA) at 577 million reais in the period, a decline of 33.7% year-on-year.

According to Natura’s financial statement, the firm faced revenue challenges throughout its operations, with net revenue reaching 5.2 billion reais in the third quarter, down 13.1% from a year earlier.

In Brazil, Natura’s largest market, where economic growth has slowed amid the highest interest rates in nearly two decades, net revenue fell 3.7% year-on-year to 3.2 billion reais.

“The slowdown in the beauty market in Brazil, first identified in June 2025 and still ongoing, has led to the growth of the Natura brand stabilizing after a period of low double-digit expansion,” the company added.

In its Spanish-speaking Latin American markets, Natura cited integration challenges following the July merger of its Natura and Avon brands in Argentina. Net revenue in these markets fell 3.9% year-on-year to around 2 billion reais.

Conflicts are consequential, but their consequences are often unpredictable. Major wars are often seen as turning points that bookend specific historical periods with distinctive geopolitical and technological contexts. So, it is natural to look ahead and try to identify the coming seismic shifts.

One of the lessons of history is that effective description does not lead to accurate prediction. Even so, it is still useful to look back at some of the well-known geopolitical, economic and technological turning points associated with war, to understand what this might mean for the future of conflict and its consequences.

Although President Trump claims to have ended seven or eight wars, there are plenty more for him to settle. According to the Upsala Conflict Data Program (UCDP), the number of state-based armed conflicts increased from 33 cases in 2013 to 61 in 2024, spread across 36 countries.

Note: ‘Internationalised intrastate’ conflict refers to scenarios where side A is always a government; side B is always one or more rebel groups; and there is involvement of foreign governments with troops.

In addition to the high-profile wars in Ukraine and the Middle East, there are numerous less well-known conflicts in Sudan and in other Sahel states. UCDP also count 74 cases of large-scale non-state violence, such as the gang violence in Haiti, and 49 cases of one-sided conflicts. These are mainly local, but many hostilities – China and Taiwan or India and Pakistan, among others – could be flashpoints that escalate into more general conflicts.

The fault lines are there, and countries are preparing for the earthquake by increasing their military spending and preparing for long wars. Even so, it is unclear whether this will make the quake less likely. Research by Efraim Benmelech and Joao Monteiro examines the relationship between military expenditure and conflict using a dataset on armed conflict and military spending for 161 countries over 75 years (from 1948 onwards). They find that even large increases in military spending produce only modest reductions in conflict risk, despite sharply raising the expected cost of war.

Wars as geopolitical punctuation marks

The historian, Eric Hobsbawm, labelled the period that began with the French Revolution in 1789 and ended with the outbreak of World War 1 in 1914 as ‘the long nineteenth century’. During this timeframe, economies were transformed by the diffusion of new technology from the industrial revolution, and the geopolitical landscape shifted with the development of Britain’s status as an economic and naval superpower. European wars were few and short, and the world became increasingly globalised.

Despite the Anglo-German naval arms race of the early 20^th century, the onset and length of World War I in August 1914 were unexpected. Even the bond markets, those sensitive indicators of geo-economic tension, did not ‘anticipate’ war until over three weeks after the assassination of Archduke Ferdinand (Ferguson, 2006). The celebrated economist, John Maynard Keynes, arranged his investments on the assumption that there would be no war. Even after the war began, famously many people expected it to be over by Christmas.

After 1918, there were probably few people in Britain who thought of themselves as living in the ‘inter-war period’.  Rather, they felt that what they called The Great War had been ‘the war to end all wars’. An exception may be Keynes. In his 1919 paper, The Economic Consequences of the Peace, he mourned the loss of the globalised world of 1914. It would not achieve the same level of openness for almost three-quarters of a century.

He also denounced the punitive ‘peace’ terms imposed by the Treaty of Versailles, whose economic effects made another war very likely – the victors inviting their own destruction. But he remained sceptical of people’s ability to predict the future. Indeed, towards the end of the book he argues that “the events of the coming year will not be shaped by the deliberate acts of statesmen, but by the hidden currents, flowing continually beneath the surface of political history, of which no one can predict the outcome”.

The inter-war period – running from 1918 to 1939 – was one of economic turbulence. The world lacked a dominant economic organising power, with Britain unable and the United States unwilling to take charge. After World War 2 came the Cold War, where the world became crudely divided between capitalism and communism. In essence, the capitalist part was organised by the United States and the Bretton Woods institutions (including the World Bank and IMF), which had been designed to prevent the turbulence of the inter-war period. For Eric Hobsbawm, the long nineteenth century was followed by a ‘short twentieth century’. It many ways it began in 1914 and ended in 1991 – not with war but with the demise of the Soviet Union. Even so, this judgement may be premature.

Wars as spurs to innovation

Major wars are not only geopolitical turning points but also remove obstacles to innovation. This gives them the potential to be times of technological transformation. Drone warfare has advanced more rapidly during the two years of Ukrainian conflict than in 20 years of US government-backed R&D. The pressure of combat speeds up arms races as evaluation of safety and reliability is streamlined, and moral and ethical issues are sidelined in favour of rapid product delivery.

The pressure to innovate applies not just to lethal weapons. The canning process was invented after prolonged research by Nicolas Appert of France in 1809, in response to Napolean needing a way of preserving food for his army and navy. It was many years later that the can-opener was invented, with soldiers using their bayonets in the first instance.

Many medical advances have also come from the experience of war, where the need to treat large numbers of wounded patients prompted experiment and innovation. For example, wars saw big improvements in wound debridement, prosthetic limbs and plastic surgery, as well as the mass production of penicillin during World War 2.

Manufacturing has also tended to change during periods of conflict. Process innovations, such as interchangeable parts and mass production, were actually introduced in UK naval arsenals and US gun manufacturers before being adopted by Henry Ford. The division of labour has its roots in the business of warfare.

The importance of military procurement for technology development prompted Vernon Ruttan to ask ‘Is War Necessary for Economic Growth?’. Writing at the turn of the century, he argued that war and the threat of war would be a less powerful inducement to technical change in the first half of the 21st century than it was during the last half of the 20th century.  Whether or not his forecast proves correct, innovation does continue without war, and in many areas, civilian technology is well ahead of the military. This is partly because of the slowness of the military procurement process (compared with the short life-cycles of generations of electronics, for example).

Even areas like cryptography, once the preserve of military and spooks, have become dominated by commercial applications. A spin-off from military research, DARPA (the US Defense Advanced Projects Research Agency) developed the internet, and a spin-off from scientific research CERN (the European Organisation for Nuclear Research) developed the World Wide Web. While GPS was originally a military system, civilian use generated a range of complementary systems – many of which are now used by the military.

Perhaps it is not surprising that defence R&D is a major source of innovation. It is the largest component of publicly funded R&D in many countries, including the United States, the UK and France. If those resources had been spent on civil R&D – without the secrecy restrictions and diversion of scarce scientific and technical skills to the military – there may have been even more ‘innovations’. As an example of the effect of secrecy, the RSA public key cryptosystem – a method for data encryption – was discovered by Clifford Cocks at GCHQ in 1973 but was kept secret. It was then re-discovered independently by Ron Rivest, Adi Shamir and Leonard Adleman of MIT, by whose initials it is known, in 1977.

Forecasting war

Given the importance of such turning points, it is tempting to try and forecast the coming conflicts and their geopolitical and technological consequences. But as Lawrence Freedman demonstrates in The Future of War: A History, we are very bad at predicting the form of future conflicts. Some of the most perceptive analysts of war have been unfortunately overtaken by events.

Immanuel Kant’s 1795 book, Perpetual Peace: A Philosophical Essay, argues that republican governments would be more inclined to promote peace and commerce, and that a union of such states could promote pacifism. Despite being followed by the Napoleonic wars, the argument remains influential and is echoed by the ‘Democratic (or Capitalist) Peace’ hypothesis, that democratic and open-market states do not tend to fight each other.

Norman Angell’s 1910 book, The Great Illusion, points out that economic integration and the cost and destructiveness of modern weapons made war so expensive that no country could gain from starting one. Although he argues that war was unprofitable rather than impossible, the book is seen by some as an incorrect forecast. While he was correct about the expense and destruction involved, that did not stop World War 1. Governments do not always understand or act in their country’s best economic interests, after all.

While World War 2 was not as unexpected as World War 1, expectations about the effects of technology, particularly about the effects of bombing, proved wrong. It was physically more destructive than predicted, but, with the exception of the atomic bomb, strategically less decisive.

The atomic bomb shaped much Cold War prediction. The black humour of Dr Strangelove and Tom Lehrer reflected widespread perceptions of likely nuclear proliferation and Armageddon. By the 1960s, new nuclear powers arrived about every five years: the United States in 1945, Russia in 1949, the UK in 1952, France in 1960, and China in 1964. Optimists – hoping the trend would continue – expected about 17 nuclear powers by 2025. Pessimists – assuming that every country that could build a nuclear weapon would – expected about 50 nuclear powers by 2025. Both groups would be astonished to know that there are now only nine nuclear powers (see Figure 2), and that three Soviet republics – Ukraine, Belarus and Kazakhstan – surrendered their nuclear weapons.

Figure 2. Total inventory of nuclear warhead stockpiles, 1946-2024

Source: SIPRI Yearbook 2025 & Federation of American Scientists (FAS)
Note: Global historical data for nuclear warhead stockpiles (1946–2024) were sourced from the Federation of American Scientists (FAS). 2024 country-specific inventory data were obtained from the SIPRI Yearbook. This methodology results in a minor variance between the aggregated 2024 FAS figure and the sum of the SIPRI country inventories.

In his 2011 book, The Better Angels of Our Nature, Steven Pinker presents data to argue that violence has declined around the world, although he did not claim the trend was inevitable. Even so, given the current prevalence of conflict, he is in danger of suffering the same fate as Norman Angell and being remembered for an incorrect forecast.

The size distribution of wars, like that of earthquakes, is ‘fat-tailed’ – characterised by rare but extreme events. The fact that there have only been minor rumbles recently does not necessarily mean that the big one is not coming. There are reasons to be cheerful; there is less nuclear proliferation than expected, the Soviet Union departed peacefully, and World War 3 has not yet arrived.

Special Meeting of Shareholders to be held on December 9, 2025

Teck’s Board of Directors Unanimously Recommends Shareholders Vote “FOR” the Merger

Vancouver, B.C. – November 10, 2025 – Teck Resources Limited (TSX: TECK.A and TECK.B, NYSE: TECK) (“Teck”) today announced the filing and mailing of its notice of meeting, management information circular and related meeting materials (collectively, the “Meeting Materials”) in connection with its upcoming special meeting of shareholders to be held on December 9, 2025 (the “Meeting”), to approve the proposed merger of equals (the “Merger”) with Anglo American plc (“Anglo American”). The Meeting Materials, which include a copy of the interim order, can also be accessed online on Teck’s website at www.Teck.com/reports and under Teck’s issuer profiles on SEDAR+ at www.sedarplus.ca and EDGAR at www.sec.gov.

Teck’s Board of Directors urges all Teck shareholders to carefully review the Meeting Materials and recommends that Teck shareholders vote their shares “FOR” the Merger. 

The Merger will create Anglo Teck, a global critical minerals leader headquartered in Canada and top five global copper producer with a world-class portfolio and outstanding future growth optionality. Through the Merger, Teck expects to deliver tremendous long-term value for its shareholders. Importantly the all-stock consideration will allow Teck shareholders to participate in the enormous upside potential of the combined company.

“This merger presents a unique opportunity to create a global mining powerhouse headquartered in Canada, offering our shareholders the chance to participate in a larger company with greater resilience, growth potential and strategic flexibility for the long-term,” said Sheila Murray, Chair. “Your Board unanimously recommends this merger, as we firmly believe it is the absolute best path forward to realize the full potential of our strategy and our portfolio.” 

“We are confident this merger of equals will generate tremendous value for Teck shareholders as well as create significant economic opportunity in Canada, underpinning our Board’s unanimous determination that the combination is the best path forward for our shareholders and all of our stakeholders,” said Jonathan Price, President and CEO. “We invite all shareholders to carefully review the meeting materials and vote for this transformative merger to create a new global critical minerals champion with significant copper exposure, leading growth, and incredible near, medium and long-term value creation potential.” 

Key Highlights of the Proposed Merger:
 

• Opportunity to Participate in Future Value Creation: At closing of the Merger, Teck shareholders will own approximately 37.6% of the combined Anglo Teck on a fully diluted basis. The terms of the Merger allow Teck shareholders to maintain their full investment and participation in future value upside at Anglo Teck, including the proposed QB-Collahuasi synergies and value creation initiatives underway at Anglo American, including near term asset optimization opportunities, proceeds from asset disposals and planned adjacencies between Los Bronces and Andina.
   
• World-Class Portfolio and Improved Growth Prospects: Anglo Teck will offer a premier portfolio of copper assets, supported by zinc and premium iron ore businesses, including:
  • Six world-class copper assets
  • One of the world’s largest zinc mines
  • Two highly cash generative premium iron ore operations
  • Near-term growth driven through asset optimization
  • Medium-term growth including through capital efficient adjacencies (including QB & Collahuasi and Los Bronces & Andina synergies)
  • Significant long-term brownfield and greenfield optionality 
     
• Compelling Value Creation Through Synergies: The Merger is expected to generate significant value for shareholders by unlocking material operational and functional synergies:
  • Approximately US$800 million in pre-tax recurring annual synergies
  • Approximately US$1.4 billion of underlying annual EBITDA synergies between the adjacent Collahuasi and QB operations (100% basis)¹
     
• Creation of a Top 5 Global Copper Producer with the Scale, Resilience, Financial Strength and Capital Markets Footprint to Unlock Re-Rating Potential: Anglo Teck will be among the largest global producers of copper with the scale, resilience, financial strength and capital markets footprint, creating the opportunity to re-rate towards a premium copper valuation multiple:
  • Combined copper production of 1.2 million tonnes, expected to grow to c.1.35 million tonnes in 2027 from current operations
  • Greater than 70% exposure to copper
  • World-class portfolio of copper and other cash-flowing assets
  • Expanded cash flow base and realization of anticipated synergies expected to result in a stronger financial profile and investment grade credit metrics
  • Enhanced capital markets profile and liquidity

¹On an average annual basis from 2030-2049 but expected to continue beyond this period (100% basis).

The Merger, which was announced in September 2025, is expected to close within 12-18 months from the date of announcement, subject to shareholder approvals and customary closing conditions, including approval under the Investment Canada Act and applicable competition and regulatory approvals in various jurisdictions globally. On November 3, 2025, the Supreme Court of British Columbia granted an interim order (the “Interim Order”) in connection with the Merger, which authorizes the calling and holding of the Meeting. A copy of the Interim Order is included in the Meeting Materials.

The Merger is supported by Temagami Mining Company Limited, SMM Resources Incorporated, Dr. Norman B. Keevil and the directors and executive leadership team of Teck, who have collectively agreed to vote shares representing approximately 79.8% of the issued and outstanding Teck Class A common shares and approximately 0.02% of the issued and outstanding Teck Class B subordinate voting shares (as of the record date for the Meeting) in favour of the Merger at the Meeting.

Board Recommendation 
The Teck Board of Directors has unanimously recommended that shareholders vote “FOR” the Merger, having determined that the Merger is in the best interests of Teck, is fair to Teck’s shareholders, and presents a highly attractive and unique opportunity to create shareholder value above the value to be created from Teck’s standalone trajectory, while lowering downside risk and preserving strategic flexibility. 

Meeting Location and Voting Details
The Meeting will be held at Suite 400-550 Burrard Street, Vancouver, British Columbia, Canada and virtually at: https://virtual-meetings.tsxtrust.com/1856 on December 9, 2025 at 11:00 a.m. (Pacific Time).

Record Date
The Teck Board has set the close of business on October 20, 2025, as the record date for determining Teck shareholders who are entitled to receive notice of and vote at the Teck Meeting. The Meeting Materials provide important information relating to the Merger, voting procedures and how to attend the Meeting. Shareholders are urged to read the Meeting Materials carefully.

This study aimed to assess self-care behaviors among Nigerian T2DM patients receiving specialized endocrinology care and to identify the socio-demographic and clinical factors influencing these behaviors. We examined five key behavioral dimensions: diet, physical activity, blood glucose monitoring, foot care, and medication adherence, and investigated their relationships with glycemic control. Our findings provide important insights into the patterns of self-care behaviors and their determinants in this population, with significant implications for clinical practice and health policy in Nigeria and similar settings. These insights should be interpreted in context. Our participants were patients actively engaged with specialized endocrinology services, who may differ from the broader T2DM population in access, education, and engagement.

The most satisfactory behaviors observed were foot examination and medication adherence, with 82.44% of participants reporting that they inspect their feet and 62.60% stating that they strictly adhere to their medications. These findings are similar to those reported in other studies [19, 20]. The high foot care adherence may be partially attributed to cultural and religious practices, as 97.33% of participants identified as Muslim and 71.37% were of Hausa ethnicity, where regular foot washing is a religious practice. However, 73.28% and 70.61% did not perform self-monitoring of blood glucose in accordance with the recommendations of their healthcare providers over the past seven days and adhered to the recommended frequency as advised by their healthcare providers. Thus, the participants demonstrated suboptimal glycemic control. This is analogous to a prior study that similarly observed unsatisfactory and poor glycemic control among their study participants, which they reported to be potentially associated with noncompliance with self-care behaviors [21]. In alignment with our study findings and those of previous research, these investigations also demonstrated that the majority of participants in the study reported inadequate adherence to diabetic self-care practices, occurring less than four days a week [22]. Noncompliance with self-care is presumed to cause suboptimal health outcomes, diabetic complications, death, or, subsequently, increased healthcare costs [23].

Our regression analysis confirmed significant associations between certain self-care behaviors and glycemic control. Dietary habits (OR 0.72, P < 0.001), physical activity (OR 0.74, P < 0.001), and blood glucose monitoring (OR 0.22, P = 0.001) were significantly associated with improved glucose control, aligning with established literature on diabetes management [24, 25]. Specifically, dietary practices significantly influenced glycemic control, reinforcing the importance of nutritional counseling that addresses cultural dietary patterns in Nigerian populations [26,27,28]. Similarly, physical activity improves insulin sensitivity and helps lower blood glucose levels [29], while regular glucose monitoring enables timely treatment adjustments [30], forming a foundation for effective diabetes management.

Several sociodemographic and clinical factors influenced specific self-care behaviors. Male gender was associated with poorer dietary management (β = − 0.19, P < 0.01), lower foot care (β = − 0.13, P < 0.05), and reduced medication adherence (β = − 0.17, P < 0.01), but better exercise practices (β = 0.23, P < 0.001). This gender disparity suggests the need for tailored interventions addressing male-specific barriers to adherence [31, 32]. Age also emerged as a significant factor, with adults over 60 showing poorer dietary management (β = − 0.19, P < 0.05), potentially due to financial constraints or declining health [33].

Notably, Igbo participants showed distinct self-care patterns compared to the predominantly Hausa sample, including poorer dietary management (β = − 0.13, P < 0.05), lower blood glucose testing (β = − 0.16, P < 0.01), poorer foot care (β = − 0.49, P < 0.001), and reduced medication adherence (β = − 0.43, P < 0.001), but better exercise practices (β = 0.19, P < 0.01). These variations may reflect cultural, social, or structural factors and highlight the need for further investigation into how ethnicity influences diabetes care [34].

Marital status influenced self-care behaviors, with single individuals demonstrating better dietary management (β = 0.15, P < 0.05) and higher exercise adherence (β = 0.27, P < 0.001), but poorer blood glucose monitoring (β = − 0.18, P < 0.01). This may reflect greater flexibility in meal planning and physical activity for single individuals but potential challenges in maintaining consistent monitoring routines [35, 36].

Our findings revealed a complex relationship between diabetes duration and self-care behaviors. Patients with longer disease duration (> 20 years) demonstrated better medication adherence (β = 0.15, P < 0.05) and exercise practices (β = 0.13, P < 0.01), suggesting that long-term experience with the disease may foster better understanding of treatment importance and develop routines that support these aspects of self-management [37, 38]. However, the same group showed poorer foot care practices (β = − 0.19, P < 0.001), while those with 11–20 years duration exhibited poorer dietary management (β = − 0.21, P < 0.001). This indicates that duration-related self-care patterns are not uniform across all behavioral dimensions. The improved medication adherence among long-term patients aligns with previous research suggesting that extended experience with diabetes management can lead to better integration of medication routines into daily life [39]. Conversely, the decline in certain self-care practices with extended duration might reflect diabetes burnout, where the psychological burden of long-term disease management leads to reduced adherence in more demanding behavioral domains [40]. Diabetes burnout has been increasingly recognized as a critical psychological barrier to sustained self-management, associated with emotional exhaustion, detachment from care routines, and increased risk of complications [41]. Addressing burnout through ongoing mental health support and routine screening may be essential for preserving long-term adherence and quality of life in individuals with chronic diabetes. These findings highlight the need for targeted refresher education and psychological support for long-term diabetes patients, focusing on maintaining comprehensive self-care practices beyond medication adherence.

It is important to interpret these findings within the context of our study population, which comprised patients actively receiving care from specialized endocrinology clinics. The relatively high self-reported medication adherence (mean score = 3.58) suggests generally good adherence behavior in this clinically engaged group. However, medication adherence was not significantly associated with glycemic control in our regression analysis (P = 0.095), indicating that its direct impact on blood glucose levels could not be established. This may reflect selection bias: regular clinic attendees are typically more health-conscious, better educated, and more motivated to engage in self-care. Such characteristics may partly explain the favorable adherence patterns observed in this sample. Moreover, the predominance of Hausa ethnicity (71.37%) limits the generalizability of our findings to Nigeria’s broader and more ethnically diverse population.

For practice and policy implications, our findings suggest several important directions that may be organized into patient-level and system-level interventions. Patient-level interventions include culturally-sensitive educational programs targeting specific demographic groups, psychological support to address long-term disease fatigue, especially among patients with extended diabetes duration. Strengthening community-based support systems can also help promote daily self-care behaviors. On the system level, efforts should focus on subsidizing glucose monitoring supplies to reduce financial barriers, particularly for older adults and individuals from lower socioeconomic backgrounds, expanding access to specialized endocrinology services for underserved populations, and strengthening healthcare provider training in culturally competent communication to address beliefs and practices that influence self-care behaviors.

This study provides valuable insights into self-care behaviors among individuals with type 2 diabetes mellitus in Nigeria; however, it has several limitations. First, as the study was conducted in two specialized endocrinology clinics in a single urban area of Zamfara State, the findings may not be generalizable to the wider population of T2DM patients across Nigeria, particularly those in rural or underserved areas with limited access to specialized care. Second, the cross-sectional design limits causal inference between self-care practices and glycemic control. Third, by focusing on patients who were actively attending specialized clinics, the study population likely reflects individuals with relatively better health literacy, medication access, and care engagement, thus the findings may not reflect the realities of patients lacking regular access to healthcare. Future research should use community-based and longitudinal approaches to explore structural determinants and enhance representativeness across diverse settings.
