The Exponential Growth of the World's Population

In 1850, the world's population numbered just over three billion. A century later, in 1950, it had reached four billion. This growth was seen as a major achievement, celebrating the victory against disease, the reduction of premature deaths, and medical advances that made it possible to correct defects and improve both the length and quality of life. Yet, at that time, the negative repercussions went almost unnoticed: the suppression of natural selection was corrupting our genetic heritage. It was understood that rapid population growth would follow an exponential curve, potentially one day crossing a critical threshold, comparable to an atomic explosion.

In just 72 years, this number has doubled, reaching eight billion today. Humanity now faces the challenge of managing this growth to ensure access to essential resources—food, drinking water, hygiene, clean air, housing, clothing, medicine, and healthcare—for all living beings, whether plant, animal, or human, on our single planet. Calls to adopt a more responsible lifestyle, to recycle more, and to consume in moderation are numerous; however, they are only truly implemented by a minority, whereas this change should concern the majority. It is regrettable that we have tried to transform "primitive" peoples living in harmony with their natural environment: today, most have disappeared, having forgotten their ability to survive in self-sufficiency without depending on the polluting tools of modernity.

Some argue that the major difficulties—famines, epidemics, declining male fertility, pollution, increased mortality due to climate change, floods, and other natural disasters—will eventually balance themselves out. The Earth has already weathered many crises and managed to recover each time. Unfortunately, it is usually disasters that trigger individual or collective action to address them.

Faced with these challenges, it is crucial to analyze the dynamics of human expansion in order to understand their consequences and identify solutions. Whether it involves innovative urban planning, responsible resource management, or educational approaches, humanity's adaptation must go hand in hand with its transformations. In a context of rapid change, every decision, personal or collective, influences the future of our world and those who inhabit it.

Over the centuries, the world's population has grown exponentially. Here are some key facts illustrating this evolution:

• In 1800, the world's population was estimated at between 813 million and 1.125 billion.

• In 1900, it reached approximately 1.55 to 1.76 billion.

• In 2000, the figure rose to nearly 6.1 billion.

• In November 2022, the 8 billion mark was surpassed.

• According to United Nations projections, the world population could reach approximately 9.7 billion in 2050 and nearly 11 billion in 2100.

• Also in 2022, the continental distribution indicated that Asia accounted for approximately 55.6% of the population, sub-Saharan Africa 14.5%, and Europe and North America 14.1%.

 

DUBAI and its remarkable transformation

Dubai fascine par son allure futuriste et son énergie permanente. En quelques décennies, cette ancienne ville de pêcheurs de perles s’est métamorphosée en une mégapole de 3,5 millions d’habitants, symbole de modernité et d’audace architecturale.

Fondée au XVIIIᵉ siècle, longtemps modeste et isolée, Dubaï a véritablement changé de dimension à partir de la seconde moitié du XXᵉ siècle, jusqu’à devenir l’un des moteurs de la fédération des Émirats arabes unis. Aujourd’hui, elle n’est pas la capitale officielle du pays, mais elle en est incontestablement la vitrine internationale.

La ville est mondialement connue pour ses projets spectaculaires : le Burj Al Arab, les Palm Islands, le World, Dubai Marina ou encore le Burj Khalifa, plus haute tour du monde. Ces réalisations ont fait de Dubaï un pôle majeur du tourisme de luxe, des affaires et du commerce.

Le développement urbain s’étend le long du Khor Dubai et de Sheikh Zayed Road, bordée de centaines de gratte‑ciel reliant les quartiers résidentiels aux grandes attractions comme Ski Dubai, Dubai Mall ou les immenses parcs à thème. La ville mêle ainsi traditions, avec le quartier historique de Deira, et innovations architecturales audacieuses.

Dubai offre une expérience unique : hôtels somptueux, centres commerciaux gigantesques, îles artificielles, mosquées élégantes comme Jumeirah Mosque, parcs aquatiques impressionnants tels qu’Aquaventure, et spectacles grandioses comme la Dubai Fountain.

Sa population a explosé en quelques décennies, passant de 265 000 habitants en 1980 à près de 3 millions en 2018. Pour accompagner cette croissance, la ville investit massivement dans les infrastructures, les transports modernes et des projets durables comme les bâtiments à énergie positive.

Comme d’autres villes en pleine expansion, Dubaï illustre la puissance de la transformation urbaine contemporaine. Comparer son évolution à celle de Hammamet permet de mieux comprendre comment les sociétés façonnent leur territoire selon leurs ambitions, leurs ressources et leur vision de l’avenir.

 

 

 

 

Urban expansion and demographic explosion

Hammamet 

The Tunisian Saint-Tropez, prized in the early 20th century by the aristocracy and artists, has transformed from a Tunisian fishing village into a true seaside resort. During that period, there were no large gatherings or multiple hotels present. The Hotel "Le Phenicia" was under construction. Tourism and the regulation of this seasonal activity were new. The intensity of capital invested in the sector would grow exponentially and extend into the other months of the year. An imbalance quickly developed between the existing infrastructure and the hotel superstructures. Moreover, in October-November, the high season was ending, and as the weeks passed, the days grew rapidly cooler. The gardeners keeping the impressive, blooming gardens of the Sheraton were attired in hats and wool sweaters. They couldn't understand how we tourists could walk around in our swimsuits on the beach and around the pool. Our child, in fact, refused to set foot on either the golden sand of the beach or the chilly water of the children's pool. Seeing our reluctance to swim, they finally heated it. The other tourists were mostly on excursions.

Our room was very spacious, and the bed in a huge alcove was the size of a harem bed. Our child would sleep in a bed provided by the hotel. Tired from the journey, she didn't fight sleep for long. On the plane, the suppository meant to calm her only excited her. In the evening, when we wanted to sleep, an incessant noise prevented us; it was a cricket that had gotten into the room during the day and taken refuge between two dressers fixed to the wall. The father had the brilliant idea of ​​immobilizing him with his wife's hairspray. 

For our child's meals, we had a supply of Fali de Fallieres jars, a specialized baby food made in Tulle, France. But once we ran out, we had to order more from the local pharmacist. Because of slow service, we rented a car, drove 60 km to Tunis, and returned with some ourselves. In the meantime, our child would only eat scrambled eggs. Fortunately, in the mornings, we had hearty breakfasts with delicious products baked overnight by the excellent baker at the hotel. The croissants were delicious, and our child ate them with relish. In Tunis, at the Museum of Handicrafts, we brought back a decorative rug to hang on the wall of the stairs landing at home.

One day, we decided to take a bus tour with the local tourists. A tire went flat, and it took the driver hours to fix it. The little girl was hungry, thirsty, and fussy because of the intense heat. So, I went to take shelter from the blazing sun in the shade of the only bush along the main road. We were going to visit Nabeul, famous for its beautiful pottery and earthenware, barely 10 km from Hammamet. We bought vibrant gold-trimmed mint tea glasses that the girl loved. Despite the mishap, the day was enjoyable. Mint tea is delicious; it must be extremely hot and extremely sweet.

1973 also saw the first declaration of the oil embargo by OPEC. From October 1973 to March 1974, the price of a barrel of oil quadrupled, reaching $11.62, with a clear negative impact on the world economy. On October 6, the State of Israel was attacked by a coalition of Arab states, including Egypt and Syria. This war served as a pretext for raising the price of oil in response to Western countries supporting Israel. The second oil crisis occurred in 1979 following revolutionary unrest in Iran, which ultimately led to the Shah's downfall.

Hammamet, thanks to its geographical, climatic, and historical advantages, has become Tunisia's primary tourist destination. Once a self-sufficient city, it has transformed into a popular and cosmopolitan seaside resort through a dramatic increase in tourism. Tourism began in 1959 when the semi-public Tunisian Hotel and Tourism Company built Hammamet's first hotel, the Miramar. From the 1960s to the 1970s, construction began on 18 establishments along the coastline, stretching from the north to the south of the city. Very quickly, private investors, faced with a shortage of beds and eagerness for profitability, expanded the hotel sector by developing establishments of distinct categories. By the end of 1980, the total capacity was 32 hotels, and since then, Hammamet has been considered the country's tourist capital, best satisfying travel agencies. Work in the sector of tourism has gradually developed at the expense of local agriculture, fishing, and other sectors such as traditional crafts. Fertile land is being used for urbanization rather than for the goal of diversifying and ensuring food self-sufficiency for the local population.

Today, tourism in Hammamet has exploded so much that there are 198 hotels in the area. This is beneficial for providing employment for women and students. However, do not underestimate the pollution that this increased activity and population growth generates, and the lack of job diversification

 Transitions to a greener world

Book by Elisa Grindale


FOREWORD

The Earth has long provided every living being with what it needed to survive. Our ancestors saw it as a nurturing mother, and this instinctive relationship drove them to take care of it. They knew, without theory or scientific model, that resources were not infinite and that the slightest mistake could disrupt a fragile balance.

Today, this bond has weakened. We move forward with less caution, sometimes with indifference, as if the riches of the planet were owed to us and were inexhaustible. How could we have strayed so far from this elementary awareness? Despite our intellectual progress, despite repeated warnings, we have too often chosen blindness. We have allowed the idea to take root that the announced disasters were just exaggerations or that technology would eventually fix everything.

The objective of this work is to revisit these choices, to examine with lucidity what our actions have produced—the worst as well as the best—in order to better understand the path that lies ahead of us. It is not about condemning but about reflecting. To recognise our mistakes in order to better overcome them. To find a way of inhabiting the world that is sustainable, responsible, and respectful of life.

Some imagine that artificial intelligence will be able to solve what humanity has not been able to master. It has the capacity for certain areas: calculation, analysis, and pattern detection. But it remains limited where humans are irreplaceable: creativity, sensitivity, fairness, and deep understanding of the consequences of our choices. AI can assist, illuminate, and accelerate—but it cannot think for us.

The risks it carries are real: security drifts, manipulations, disinformation, human rights violations, and weakening of our own cognitive abilities. The real danger lies not in the tool itself but in how we use it, in how it will influence our behaviours and our relationship with the world.

This book is an invitation to face what we have become and to imagine together what we could become again.

 

Conflicts

Armed conflicts never solve geopolitical problems, and they sometimes last a very long time. Sudan is in a forgotten war, deliberately ignored by the world because of its complexity. Rebels clash with government troops while the weakened population has been suffering from famine for decades, causing an unprecedented global crisis in the region.
They often cause more suffering than concrete solutions, leaving fractured societies, weakened economies, and generations marked by the loss of loved ones. Force does not guarantee peace; only dialogue and cooperation can. Rather than resolving disagreements, wars reinforce mistrust and prolong instability. Destroy cities, countryside, lives, structures, and historical sites. Countries can sometimes take a century to rebuild afterward.
It is crucial to rethink our methods for resolving conflicts. We must invest in preventive diplomacy, peace education, and structures to promote international mediation, rather than consider war  inevitable. Societies that listen to and seek compromise foster innovative solutions, meeting the aspirations of people without violence. Humanity should exchange weapons for speech to build bridges instead of walls. Wars are expensive and harm the economy and budgets of countries, which could invest that money in science and education.
Adopting this perspective involves revisiting collective memory and listening to the stories of survivors and affected communities to draw lasting lessons for the future. We must recognize the resilience of those who, despite the scars of war, work to rebuild the social fabric and promote peaceful values. Moreover, citizen engagement is crucial: by participating in solidarity actions and by supporting access to education and culture, everyone helps to ease tensions and promote mutual respect. In short, relying on collective intelligence and human creativity fosters true peace based on shared justice and dignity. Numerous current examples show how a strong commitment to peace can transform the destiny of nations on a global scale. Disarmament actions, reconciliation processes, and intercultural exchanges show the great potential of human cooperation. We must draw inspiration from the successes of multilateral dialog, where understanding the other is more important than victory. By focusing on conflict prevention through education, exchanges, and diplomacy, societies avoid losses and cultivate a culture of respect and shared responsibility. This ambitious horizon requires collective mobilization and a continuous questioning of our governance models and priorities as a global community. Finally, let's remember that peace is not just the absence of war but a dynamic process requiring vigilance, commitment, and creativity from everyone. It is based on social justice, equity, and respect for the dignity of all. By investing in these values, humanity will be able to overcome destructive cycles and build a future of solidarity and reconciliation.

 Each month, thousands of Sudanese flee to neighboring countries. A year after clashes between armed factions, Sudan remains at war, with 15,000 dead, eight million civilians displaced, 25 million in need of assistance, and an imminent famine. Since mid-April 2023, a wave of violence has been sweeping across the country without interruption. Humanitarian aid workers often must leave the territory due to the dangerous security situation, endangering their most courageous volunteers. Although humanitarian supplies are available in Port Sudan, they are hampered by looting of warehouses, bureaucratic obstacles, insecurity, and communication breakdowns. According to UNICEF, children are the main victims. The older ones are forcibly recruited by armed groups. Women and girls have been raped, leading to new pregnancies. Some are too weak to feed their babies. We are entering a vicious cycle that is difficult to break. Militias are killing people based on their ethnicity. A ceasefire seems impossible; the international community must bring the opponents to dialogue to avoid disaster for the Sudanese people, and the future of Africa's third-largest country is at stake. The survival of millions of people is at risk, as well as the stability of a region exacerbated by a growing famine. This war is destroying agriculture, businesses, and national economies; after this, it will be complex to get the economy back on track.

Paris between luxury and extravagance

 

Watercolor and ink by Amarie

Paris, nicknamed "the City of Light", never ceases to fascinate, inspire, and make people dream. It is a place where history and modernity intertwine, where luxury meets excess, and where every street, every boulevard, seems to vibrate to the rhythm of rare elegance. Capital of refinement, fashion, and art, Paris alone embodies the epitome of style and urban extravagance.
The light of Paris, whether it is that of the golden lampposts lining the Seine or that of the sparkling shop windows of Avenue Montaigne, symbolises much more than just nighttime lighting. It is no coincidence that Paris was the first major European city to adopt public lighting in the 18th century, thereby reinforcing its reputation for avant-gardism and innovation. A city of intellectuals and creators, it welcomes millions of visitors each year who come seeking inspiration and wonder.
From the splendours of the Eiffel Tower to the flamboyant stained glass of Notre-Dame, Paris shines with its architectural heritage. The museums, such as the Louvre or the Musée d'Orsay, house invaluable treasures that make Paris a universal cultural capital. The mythical squares—Place Vendôme, Place de la Concorde, and Place des Vosges—are so many jewels that punctuate the city, bearing witness to a splendour that has never waned.
In Paris, luxury is not limited to a simple material notion: it is rooted in the very soul of the city. The high-end fashion boutiques, the century-old palaces, the jewellery workshops, and the grand Michelin-starred restaurants embody this unique expertise. On the Avenue des Champs-Élysées, in the hushed salons of the Ritz or the Crillon, the notion of service reaches peaks of perfection.
Paris is the cradle of haute couture. The biggest names have set up shop there: Chanel, Dior, Louis Vuitton, Hermès... Every year, Fashion Week transforms the city into a theatre of elegance where designers, models, and trend enthusiasts gather. In the Marais, Saint-Germain-des-Prés, or Faubourg Saint-Honoré districts, each boutique competes with creativity and exclusivity.
Luxury is also discovered through gastronomy. The starred chefs, such as Pierre Gagnaire, Guy Savoy, or Alain Ducasse, make the taste buds of gourmets from all over the world vibrate. The famous pastry chefs—Yann Couvreur, Pierre Hermé, Philippe Conticini, Cédric Grolet, Cyril Lignac, Jacques Genin, and Sadakaru Maki—offer creations that are as much sweet works of art. The markets, the historic wine cellars, and the cheese shops all contribute to this daily celebration of French refinement.
Paris is a city that dares and has fun: its extravagances are legendary. In the social evenings of palaces and private clubs, the party is adorned with excess and gentle madness. The Moulin Rouge, the Crazy Horse, and the legendary cabarets make Parisian nights dance under the spotlight, where glamour mixes with audacity.
From fashion shows to costume balls, Paris loves spectacular staging. The city hosts the largest international trade shows—Maison & Objets, Paris Photo, and FIAC—as well as prestigious galas in museums or private mansions. The fireworks on July 14th and the Christmas lights on the Champs-Élysées transform the city into a magical setting.
The Parisian art scene is just as vibrant, from the discreet galleries in the Le Marais district to the bold installations at the Palais de Tokyo. Rooftop evenings, hidden bars, and festive cruises on the Seine offer many opportunities to experience Paris differently, in an atmosphere that is both eccentric and refined.
If Paris shines with all its splendour, it remains nonetheless a city that knows how to evolve. The new neighbourhoods, such as the thirteenth arrondissement or the La Défense area, bear witness to urban dynamism and embraced modernity. Ecological initiatives, the rise of design, and avant-garde architecture are integrated into the Parisian fabric, blending respect for traditions with bold innovations.
From the splendour of the Opéra Garnier to the conviviality of small bistros, from majestic gardens to narrow cobblestone streets, Paris captivates with its contrasts. You encounter all cultures, all styles, and all desires. It is this mix, this effervescence, that makes Paris a unique city in the world.
Paris, the City of Light, is not just about its monuments or its history: it is, above all, an invitation to celebrate beauty, luxury, and extravagance in all their forms. Whether you are just passing through or a resident, Paris offers everyone the opportunity to dream, to marvel, and to experience a city where anything becomes possible thanks to the audacity and creativity of its inhabitants. A true jewel in the heart of Europe, Paris remains and will continue to be an unparalleled reference, a symbol of an art of living that fascinates and inspires the entire world.

It is not surprising that part of my family lives there. It’s difficult to dislodge and understand them, especially as they live with four people in an area of only 40 square metres. I suppose this is the price to pay to live in a luxury metropolitan city. Of course, my son has managed to land an exciting job at the company T.E.S.S., and my daughter-in-law has more opportunities to find interesting employment. I bless them.

Maternity

 

Drawing with color pencils by Amarie 

Young bride, it is a state that one hopes for and dreads at the same time. It is the unknown world that opens to the young woman, and the doubt remains about whether she can handle all the stages up to childbirth, the course of which and the outcome of which are unknown. It is a journey of emotions, challenges, and discoveries. Motherhood is much more than just a state. It is a complex journey filled with intense joys, upheavals, and unique experiences.
The only thing I realized with certainty was that the average duration of a pregnancy is nine months. I found this term extremely long! My pregnancy was accompanied by multiple physical transformations: weight gain, changes in body shape, hormonal fluctuations, mood swings, sudden fatigue, cravings, uncontrollable hunger, and the emergence of new ailments like aversion to the smell of morning coffee and, above all, digestive issues characterized by nausea and vomiting. These changes were both a source of fascination and discomfort. On a psychological level, my day was divided between an ambivalence of happiness and apprehension, an oscillation between serenity and anxiety in the face of the unknown. Fortunately, time was precious, and the profession engulfed all my worries. Besides, I had no one to confide my doubts and my anxieties to and to seek advice from. "Each pregnancy is a unique journey," my dear family doctor assured me. "Don't worry, I'm here!" My prenatal care was provided by a physiotherapist with her weekly light exercises, regular check-ups with my gynecologist in Bruges, and my local doctor for minor ailments. They all try to reassure me as best as they can to ensure a positive pregnancy. My delivery would take place, if possible, in a hospital setting. I worked until the evening before, making sure to give birth before the medical service opened the next morning with an ultra-fast, taxi-style delivery.
My motherhood was ahead of its time in the difficult context of the movement for women's place in society and the not-so-easy reconciliation of professional and family life at the time. We were already exposing ourselves to numerous family and societal criticisms, firmly challenging ancestral norms. While the support of those around becomes crucial during the pivotal period in the lives of the mother and child, one struggles with misunderstanding, exhaustion, hormonal upheavals, identity questions, baby blues, and the increased mental and physical load. It is a delicate transition where the mother-child relationship is established and the confrontation with the new role, that of a parent, takes place. My primary goal: to be a good mother despite the challenges. Succeed in balancing everything, offering the best to your child. It was essential to value my atypical journey, to accept imperfection, and to remind myself that every story is legitimate. Despite the challenges, motherhood is rich in happiness: first smiles, first steps, shared discoveries, and bonds that are woven day by day. The relationship with the child, filled with tenderness, wonder, and sometimes challenges, profoundly transforms the one who becomes a parent. Motherhood is also about growing with your child, questioning yourself, learning to let go, and passing on values. It is a journey marked by doubts and bright moments, fatigue and laughter, worries and pride.
