As the world approaches COP30, discussions about forest restoration increasingly revolve around numbers: hectares protected, carbon absorbed, funding allocated. But a forest is not defined by surface area or carbon metrics alone. A forest is a structure of relationships. It is pollination, memory, dispersal, seasonal timing, learning passed from mothers to young, movements that depend on architecture. Restoring a forest means restoring continuity. It means allowing seeds to travel again, allowing families to remain in territories that hold their histories, allowing calls to carry across valleys, allowing bodies built for trees to stay in the trees. Conservation cannot be separated from the communities who live among these forests, whose knowledge and ​livelihoods shape their futures. And long-term field research is not optional; it is what allows us to detect these subtle shifts before they reach a point where recovery is no longer possible.

Some days change something. Not because of a spectacular event or a scientific breakthrough, but because you can feel it — quietly — a new relationship with the ocean taking shape. Today was one of those days.

It began with a simple question on the boat, as it often does.
One of the young divers asked me how many sharks are killed every year.
When I answered 70 to 100 million, the whole group fell silent.
Then came the second question:
“But… why?”
And that’s when everything started moving: industrial fishing, finning, the disappearance of a predator the ocean desperately needs. Then we talked about the role of turtles in Mayotte --
the gardeners of the lagoon — cleaning seagrass, redistributing nutrients, maintaining a fragile balance very few people know about.

These simple exchanges are where sparks begin.

The “Naimi Effect”And then there’s Naimi.
When she joined the program, she was preparing for her math–physics baccalauréat, bright, focused, heading toward the classic science path.
But dive after dive, something shifted.
She started asking different questions. Not just “how does this work?” but
“could I work in this field one day?”
Today, she says out loud what she barely dared to think a few months ago:
she’s considering marine biology.
That’s not a small turn — it’s a whole life pivoting, quietly, shaped by experiences underwater, by encounters, by understanding.
When a 17-year-old begins to look at the ocean not as a backdrop but as a possible future,
it means something real is happening.

Diving Is No Longer a Hobby — It’s a Doorway. The questions are changing.
In the beginning they asked:
“Is it deep? How long will we stay? What fish is that?”
Now it’s becoming:

• “How do you become an instructor?”
• “What comes after Level 2?”
• “Can you work underwater?”

They’re moving from enjoyment to projection, from discovery to aspiration,
from experience to vocation.
It’s exactly what I hoped for — quietly, secretly that diving wouldn’t just be an activity, but a gateway to a deeper understanding of their island, their lagoon, their future.

A New Relationship with the OceanSharks, turtles, seagrass, reefs…
These are no longer abstract words.
They’re things they’ve seen, felt, understood, protected.
A new relationship with the ocean is taking root.
Not through big speeches --
but through accumulated experience:

• putting on a wetsuit,
  
• learning to breathe underwater,
  
• being watched by a fish,
  
• floating in the blue,
  
• realising you belong to something larger.
  

It’s these small moments that redraw an entire future.

And Me, in the Middle of All ThisI watch them evolve, grow, open up.
This isn’t just a project.
It’s a transformation.
Each time a young diver tells me,
“I’d like to work in the ocean too,”
I feel that all the hours teaching, filming, reassuring, guiding…
they all land somewhere meaningful.
The Ambassadeurs du Lagon are no longer teenagers learning to dive.
They are slowly becoming the Sentinelles du Lagon --
the future guardians of a world they’re only beginning to understand.
And that might be the most beautiful thing I’ll have witnessed here.

For some of Mayotte’s young lagoon ambassadors, this third session feels like a liberation. For others, it’s a confrontation with themselves — a moment when the water reflects not only the reef below, but also the fears they carry inside.

​While a few have already found balance underwater, gently exploring the coral and the first signs of life awakening on the reef, others still face an invisible wall: fear.
The fear of drowning, of losing control, of that first breath that feels too big, too heavy, too new.

Ouksam, a talented athlete and excellent student, faced that wall today.
Accustomed to success, he suddenly found himself unable to descend the six metres that separated him from the bottom. The hardest part wasn’t the depth — it was the realization that courage sometimes means admitting weakness, accepting that not everything can be controlled.
The real dive begins within.

Nearby, Karimou, usually quiet and reserved, faced another challenge.
His first dive had been painful — pressure in the ears, discomfort, hesitation.
He arrived that morning unsure whether he would even go back into the water.
But he did. This time, he stayed for an hour, calm and present.
That single hour might have changed more than he knows — confidence built in the lagoon often finds its way into life on land.

And then, beyond these small personal victories, something unexpected happened.
One of the students decided to take his experience further — choosing to prepare his Grand Oral exam around the physics and biology of diving, exploring pressure, gas exchange, and what really happens in the body when we descend. It’s a sign that the project is working — that curiosity is awakening, that education can flow naturally from experience.
Between fear and fascination, each descent is a metaphor: learning to trust the sea is learning to trust oneself.

The day began with an unexpected gift. Just a few hundred meters from the dive club, a group of dolphins appeared, cutting through the calm surface as if to welcome the Ambassadeurs du Lagon to their world. For all the young participants, it was a first — a fleeting encounter filled with wonder, laughter, and wide-eyed amazement. Sometimes nature speaks first, and in that moment, it said everything. When we take the time to look, our planet truly is extraordinary. The smiles, the shouts of joy, and the stunned faces of these young divers said more than words ever could about the connection between humans and the sea, once the meeting finally happens.

Then came the dive. Ten meters below the surface — their very first Level 1 session. On the program: descent along a rope, mask clearing, regulator recovery, buoyancy control with the BCD… and above all, the thrill of discovering the underwater world together, in teams of four. Out of ten participants, three struggled a bit with ear equalization, while the others quickly found their rhythm. What impressed most, seen from behind the camera, was the natural ease of the girls — serene, focused, graceful — even though most of them had never really swum or dived before. Confidence was taking shape, quietly, and that confidence will go far beyond diving or the protection of the lagoon.

Much of this calm came from the instructors. The Abalone team brought exactly what was needed: patience, trust, serenity. The way they moved, the tone of their voice, the quiet gestures that seem simple but mean everything — all of it created a safe space. A good instructor doesn’t just teach; he transmits. He passes on an attitude, a balance, a way of breathing underwater that shapes the diver as much as the dive itself. Today, that transmission was in full flow.

When the group surfaced, the energy had shifted. Smiles everywhere. Pride glowing in each face. Even those who felt less confident found their place, drawn back into the shared joy of the moment. Bonds had been formed — underwater handshakes, a pat on the shoulder, high-fives mid-descent. Back on the boat, everyone was still laughing, replaying the encounter with the dolphins, and already dreaming of the next dive. The lagoon had done its magic: ten young people, a little braver, a little prouder, and forever changed by what they had just discovered.

Yesterday, while reading “Vive la resilience: don’t write off our corals just yet” published by Oceanographic Magazine, I felt an unexpected mix of emotions — a sense of genuine hope, knowing that some reefs still show signs of resistance, and yet, a deep lingering doubt.

Far be it from me to question scientific voices — I know the rigour, the countless hours spent observing, measuring, understanding.
But this optimism, as necessary as it is, raises a fundamental question: how far can we speak of hope without lying to ourselves?
When scientists say “not all reefs are lost,” is it a cry of resistance… or a sign of an institutional need to stay heard ?
​
As I read those words, I couldn’t help thinking about what I see underwater every week: bleaching spreading like a slow tide, colonies dying quietly, and parts of the lagoon where life simply fades away.
Maybe not everything is lost — but we must still have the courage to admit that some of it already is.

Scientists Live on ProjectsIn science, hope isn’t just a feeling — it’s a condition of survival.

To secure funding, you must convince others that solutions exist, that research can still turn the tide. A project titled “the end of coral reefs” will never receive a grant; one that speaks of “resilience” or “regeneration” almost always will.
It’s human, even understandable. But when science becomes dependent on narratives of hope, the gravity of reality gets blurred.
​
And the risk is clear: truth — the uncomfortable kind — dissolves into the language of promises.

Hope as an Academic Survival Strategy In a world oversaturated with bad news, hope has become a tool of communication.

Institutions need it — to keep public support, to soothe fear, to maintain trust.
So we speak of resilience, of rebirth, of corals adapting to change.
All of that exists, of course; some reefs do resist better than others. But when we repeat too often that “nature can heal itself,” we normalize irreversible damage. If hope becomes an academic strategy, we are no longer talking about science — we are talking about narrative survival:
a discourse fine-tuned to reassure funders, governments, and sometimes our own conscience.

Science Under Narrative Influence Science is never completely neutral; it evolves within its era, language, and politics.
When a study highlights signs of resilience rather than signs of collapse, it’s often a matter of framing, not manipulation.
But the accumulation of these choices creates a trend — a form of science shaped by its narrative.
​
Not because it lies, but because it selects what to show to avoid despair.
It’s subtle, almost invisible. Yet it changes everything.

It turns science into a kind of benevolent storytelling, where lucidity becomes risky, and hope an unspoken moral duty.
Behind that narrative, however, lies a simple reality: without funding, research stops.

Scientists must persuade their sponsors — public or private — that their work will lead to solutions, not just acknowledgements of failure.
In this system, the language of hope becomes almost a currency: it unlocks grants, European programs, political endorsements.
In other words, to keep working, one must keep believing.

The Sincere but Biased Faith Most scientists I meet are sincere.
They believe in what they do — and they still hope.
And thankfully so: without that flame, who would dive again on a dying reef?
But sometimes that faith in coral resilience becomes so strong it blurs critical distance.

We begin to confuse wanting to believe with seeing what is.
And that’s where danger begins: when hope takes the place of truth, we stop measuring the true extent of loss.
We talk about regeneration without admitting that it takes decades — sometimes centuries — for a reef to rebuild.
Resilient corals do exist — often deeper, between 20 and 50 meters.
But that resilience raises another question: at what ecological cost do they survive?

A deep reef doesn’t offer the same light, the same warmth, nor the same biodiversity as a shallow one.
If the future of coral shifts to those depths, the balance of tropical lagoons will change entirely:
herbivorous fish disappear from the shallows, food chains reconfigure, and coastal fisheries — lifelines for thousands of families — become increasingly unstable.
​
In other words, coral resilience does not guarantee human resilience.
It merely pushes life to places where we can no longer see it.

When Everyone Speaks, Who Tells the Truth?In a world where funding, science, media, and politics constantly collide, the role of the field reporter — the one who goes, sees, and listens — has never been more essential.
Because even when science remains sincere, it is rarely free from influence.
Many scientists I’ve met are in the water, day after day, facing the same realities we do. Their commitment is unquestionable.
But the system they work within — the race for grants, visibility, and recognition — can shape how truth is told.
When your next expedition depends on a funder’s approval, when “hope” sounds better in a proposal than “collapse,” it becomes harder to speak without filters.
Some projects blur the line between research and personal ambition, between fieldwork and privilege.
It’s not corruption; it’s the quiet pressure of a system that rewards optimism more than honesty.
When scientists publish opinion pieces or “hope essays,” they often do so with sincerity — but without contradiction, or without the space for facts and data that challenge their narrative.
Few journals give room to opposing analyses on the same topic.
The result is not misinformation, but imbalance.
A subtle shift where communication starts to replace truth.
And this is precisely where the work of independent photographers, divers, and field journalists matters.
Not to oppose science, but to complete it.
To bring back the tangible — what the ocean actually looks like, smells like, feels like.
To show that truth doesn’t always come from a lab or a grant, but sometimes from the quiet evidence of being there, eyes open, camera in hand.

Hope is vital — it drives us to act, to protect, to educate.
But it should never become a filter that softens reality.
Because behind every optimistic sentence are images I can’t forget:
corals white as ash, fish circling in emptiness, once-vibrant zones now silent.

They are not even “white corals” anymore — the coral is gone, replaced by bare rock.

Between hope and alarmism lies another path — that of truth.
To tell what we see, without exaggeration, without dilution.
To remind ourselves that resilience does not erase human impact, and that survival at depth does not equal recovery at the surface.
Yes, some reefs endure. But most decline.

And to speak only of resilience, without showing that decline, is to risk normalizing disaster.

Because in the end, doesn’t this constant optimism serve, ironically, as the victory of climate sceptics?
By reassuring, we disarm.
​
By saying “not all is lost,” we delay urgency.
And by the time truth finds its voice again, the ocean will already have changed its face.
