« Si nous ne faisons rien, dans 20 ans la Méditerranée sera une mer morte ! ». Cette phrase dite par Jacques Yves Cousteau en 1979 est toujours d’actualité et, comme bien souvent, il y a une bonne et une mauvaise nouvelle.

La bonne nouvelle c’est que des mesures ont été prises pour que la Méditerranée ne meurt pas. La mauvaise, c’est que plus de 40 ans ont passé et les journaux titrent toujours cette même phrase.

Mais qu’en est-il réellement ? Le combat est-il perdu d’avance ? Quelles ont été les mesures mises en place ?

Mediterranean Sea. Please
unlock your iPhone first. I’m not sure who that is. What is your mother’s name? He doesn’t understand anything. Mediterranean Sea. Here is some information. So, the Mediterranean,
a better trash can. It’s starting well. Will the Mediterranean survive the summer? Record temperature in the Mediterranean,
no, no. I’ve had it up to here. Alicia, you closed the bottle. I know it’s you. Damn it. Come on, that’s enough. Where is my bathrobe? Mediterranean. Conservation is no longer enough; we
must repair the ecosystem. I’m repopulating the sea. Saving the young people, I’m fed up with them. Donia application. That’s Posidonia. We must act. Remember, impossible missions
are the only ones that succeed, Frank. Is anyone there? Commander, is that you? I have to stop taking the bath. Come on, Frank.
Bill? Yeah, just do it. Me ? What can I do? Okay. Well, I decided to keep a journal
to talk about the Mediterranean. In fact, I’m fed up with seeing
in the media that people are always saying that the Mediterranean
is the most polluted sea in the world, that it’s dying,
that it’s over. In fact, when you look a little,
you realize that there are people who are working precisely
to make her feel better. And I decided
to put them forward. I decided to talk about it. So, I don’t know if I’m the most
legitimate, but in any case, it’s my decision. And there you have it. So, I pack my things and
go south. It can’t be there,
it’s not possible. I’m completely lost right now. Gilles? Is anyone there? Ah, there’s a sign, that’s good. Scottish? I’m coming, it’s you. Gilles? Hi. How are you ? Did you find us? Well yeah, yeah, it’s not easy. Are you doing well ?
Yeah, good, and you? Yeah, good.
So this is the farm? It’s the farm that allows us
to repopulate the sea, yeah. With different techniques.
All right. So, Damien is over there in the Farm. And then, once you want to
see everything you’re going to see with Damien, he’s going to show you the small aquariums with
the small fish, the medium fish, the large fish. And then he will go diving with Antho
and see the biots, for real. Awesome, I love it. Plus, the weather is great
there, so it’s great. Yeah, that’s cool. Hello, is this Damien?
Yeah, that’s it. Nice to meet you, Franck.
Delighted. So what is it here? This is the Caciumar project from Écosséan. We do ecological restoration
and therefore we fish for larvae in Cassis, Siota, Marseille. We repopulate six months later. Okay.
Go ahead, show me. Come on, well,
it was feeding time, so I’ll be able to show you.
We’re going to feed them. Come on. The youngest stadiums we have
are the Pocelars. There, you see, I have some plankton
and we’re going to be able to distribute some. There, it’s really very
small shrimps that we give them. We can hardly see anything. That’s
it. There, it is a fairly small food
that is adapted to the size of the mouth. Just above,
we have an agreement with wolf. So here I’m going to give them
a little bit of plankton. Come on, come down right away.
They are much more lively than the others. These ones are a little older,
a few days. All of these are animals that
are about 20 days old, a month old. So there, we raise them in a small aquarium. And then, behind, precisely,
we will take care of feeding certain basins where the animals
are a little bigger. In fact, we are going to compensate for the mortality
that we have in the natural environment. Overall, it is estimated that only one percent of the
tree stock in the natural environment
reaches the coast. Here, we’re going to have over 80
percent survival rates because they’re…
It’s a huge difference. That’s it. And all this because, in fact,
they are in good conditions. And you eat them after the fish?
No not at all. The goal is to repopulate them
and put them back in the big bay. All right. It’s crazy, this fish farm,
with adolescent fish, it’s a bit like a boarding school, you know. Well, exactly, at this stage of life,
we can compare it to that. And now, here, I’m going to show you,
we’re going to change the atmosphere. We are going to enter a
coralligenous farm. So, we are in the experimental phase,
we are the only ones doing this. Oh yeah, so it’s
a bit top secret, then. Exactly.
Come on, let’s go, let’s see about that. It’s a nightclub atmosphere, basically.
What is this light? The goal here is to really recreate
an atmosphere as if we were 50 meters deep, because that’s
the depth from which they were taken. And so there, we are more or less at the
light, I would say, at the peak. It’s really maximum.
Maximum light, yes. We don’t see much of that. And then it’s super cold. Exactly, because there we
also recreate the temperature of 50 meters. So we’re at about 16 degrees. So here, you have the three basins,
in fact, these are the basins where we have the sea feet. That is to say that from their
branching, I will be able to take a cutting. So show me. There, all of this is tubs
whose cuttings come from the sea feet we have behind our backs. There you have red coral,
you have orange gorgonians, you have purple gorgonian cuttings. This is more or less
an experimental stage. In fact, we take cuttings here
on this farm, in this lab, to then replant them in the
natural environment and then monitor them to see if there is still good recovery,
good growth in the natural environment. The solution to come
is to say to ourselves: We could make cuttings on a larger scale
to be able to replant them in ecosystems that
need a little help. Okay, that’s the goal. That’s the system, consolidate it.
Exactly. Ecosystem.
That’s exactly the goal. And you told me, Andromeda too, is going to
replant these gorgons 50 meters away. That’s it, they are
partners in the project. They took the samples and it is they
who then take care of putting the cuttings back into the natural environment and following them up after the colonies
. We’ll try to go see that. I’m going to show you
a repopulation video. This is a repopulation that we
did in Toulon last year. There, you see, we have the divers who… What do they have in their hands? In their hands they have traps. We caught the fish in the morning. So you picked them up from the farm? We picked them up from the farm. There are about 80-100 per trap. And so there, you see, we arrive
at the repopulation site. So we made villages. And there, the goal is that the divers
will bring the traps to these different places. So there are about four bells there. And so there are
fish that are six months old. These were the ones we saw. That’s
it. They are six months old.
There, it’s the end of the cycle. They are about 7 to 10 cm. All of this helps
them to acclimatize well. And then, you see, the next day,
we go back to the site and we free them. So afterward, depending on the species,
the animals can stay around for a little while, discover the environment a little. It’s funny, because then
they come towards you, towards the divers. It’s funny. That’s
it. It can last a little, a few minutes. And then afterward, generally,
they blend in. They blend in with other fish that have
remained in the environment. All right. There it
is, I’m starting to understand. And it’s nice to see that
things are happening and, above all, there are solutions.
Yeah. THANKS. Well, I’m looking forward to discovering
the logs now. Come on. Antho. Antho? Hi, Franck.
Didn’t you hear me? I can’t hear anything there, there’s a choppy
sea and everything, it’s complicated. I’m done here, if you want, we can go
behind, we can go to the other one. Okay.
And the rock tour over there. Come on, it works.
Here we go. Come on. Hi.
Hi Franck. How are you ?
It’s good and you ? Careful, it’s true that… Wait, I’m getting my eyes back. Is this the oil can? Exactly, that’s the cruet.
All right. Oh yeah.
You see, it’s made up… It’s a cage that’s made up
of steel and oyster shell. Yeah, it’s good.
The idea, if you like, is a habitat. If I can give an image, it’s like
an insect house, but in water. So, we will have a lot of fauna and
flora that will develop around it. And the idea is to restore a
habitat function to areas that have been modified upstream. Here, in a large port like the port
of Marseille, at one time, we had small coastal areas. These small coastal areas
were places that served as killing grounds. And so, young coastal fish,
so I’m going to make a big deal of generalizations because there are
plenty of exceptions, obviously. But generally speaking,
young coastal fish, when they are very young,
come back to this coast to settle and begin their growth. They are looking for a habitat to protect themselves
from predators and to eat, obviously. And so, in artificial places
like a port, where you have concrete calis and mud around, in fact,
habitats, there are more of them. There’s nothing to protect yourself with, really.
Exactly. So, the idea we had
at Ecoseterrance was to give
these spaces an ecological function by equipping them with more virginal habitats.
No, houses for them, and food. Exactly. Well, that’s great,
we’ll see that often. Well, if you want,
I can take you to see them. We have some right there behind me.
Well, come on. We’ll go get the blocks
and then I’ll show you this. Come on, wait, I’ll get them.
Come on, please. Oh, I forgot. Oh no, only Mimi is coming.
Wait, I’ll try this. Oh yeah, I know. Ah, well, that’s good.
Come on, let’s go. This is the first time
I’ve dived in a port. Who saw it? Oh yes, a blenny. Indeed, it is full of fish. I enjoy diving with Antho,
but my next mission awaits me. After the fish, the herbs. I didn’t know there was grass
in the sea, but apparently Andromeda is replanting it. Ooh there, ooh there there there there. I shouldn’t fall in front of them there. Hi. How are you ? It’s good and you ?
Yeah. Welcome aboard.
Thank you so much. Hop. GOOD. I hook it. You wait until it’s okay, he leaves.
Perfect. So, I saw that there were plants.
That’s where little Denis was pulled out.
And what are you doing there? Are you replanting them?
How is it going? Well, yes, look, that’s what we
collect. And we put staples on it. This way, we prepare it
to make it easier to anchor. There, you see, we finished this box. What we did was we were
going to transport her there. Niels is coming to pick her up. He transports it to the surface and we
dig it down, he sends it to us and we recover it. We open it and take out
the fragments and replant. Okay.
Niels? You can go. Hello ?
Okay, let’s get ready. Come on. She is happy I saw that the surface area
of ​​Posidonia, just in France, is eight times the size of Paris. All right.
So it’s really gigantic. It is a plant that has some
quite exceptional characteristics. She has two reproductions. One by the rhizomes This is what we saw
when we graffitied, we put around the rhizome,
so it grows like that and it has sexual reproduction via the flowers. And the seeds that will… disperse with the currents.
Exactly. That’s the species, but that species
actually creates a complete ecosystem. It structures a complete ecosystem,
the Posydonia ecosystem, where more than 1,000
animal species and 400 plant species come to shelter. This is called the
Posydonia ecosystem. Which has many roles for the
Mediterranean, for the functioning. It’s a habitat,
it’s going to be a nursery area, it’s going to be a spawning area
for many species. And it has a role, like that, pumps CO₂ and emits oxygen. It is said to be a great
carbon pump and therefore limits global warming.
I heard about a carbon sink. Exactly.
This plant is also threatened. What is the first threat? So, for a very long time,
we had a water quality problem. In the Mediterranean,
more than 20, 30 years ago, there was a lot of discharge,
a lot of chemical pollution. And we put a lot
of effort into that. So, thanks to that, we have
much better water quality. Thanks to the treatment plants, in particular. Sewage treatment plants. And so the plant
takes to the streets much better. Except that we have moved on to another
problem, which is anchoring. This is the primary cause
of degradation of the seagrass. That’s why we’re replanting it. Everything that is torn out, everything that is
replanted, has been damaged by the anchors. And when we draw a parallel,
because what we find a shame is that on land,
we wouldn’t ask the question. That is to say, if you go to the forest,
like the Posidonia forest, you are not going to park your car,
cut five hours to park your car. Yet, that’s what we do in the summer. That is to say, to stay on the surface,
we send the anchor and no matter what is underneath, we tear out all
the forest underneath. So, that’s what I
find a bit of a shame. And so, for that, in fact, there
is an application called Donia, which Johan will tell you about in detail. And so you can go see it and you
will see, it’s a great application. That works.
Thank you very much, Sébastien. It was nothing. See you soon. See you
soon. Johan?
Yes ? Can I see you for five minutes? Absolutely, come on, sit down. I heard you had
some stuff to show me. Yes, I heard that Sébastien was talking to you
a little bit about anchoring in glassworks.
Exactly. I don’t know if you’ve
seen this video before. What is a video about what?
On the anchors? This is a video about the impact
of anchoring on the Posydonia in the Mediterranean. The idea was to show me what was
happening underwater, since we had already seen, while doing
some studies, enormous scars in the seagrass beds. We did a bit of
sound campaigns and we saw thanks to this machine that there were
big trails in the herbarium. Divers went
underwater to take videos. And we realized that there
were these famous impacts of yachting. Yes, they are big boats. There are also small boats. Like there, it’s a pretty small anchor. You should know that
the bigger the boat, the heavier the anchor and chain. They are heavy and are huge. The impacts are not the same. But the idea was to show… It’s right in the middle of the field. The anchor was pulled out,
but also the chain was dragged. It’s huge. The diameter is enormous. It’s like a furrow,
as if a farmer had gone through with a machine and had Yes, the field. It is a
complete dredging of the seagrass. Obviously, as Posidonia takes a
long time to grow back, you get these scars.
Yes, we see these big streaks. For hundreds of years. On a human scale, this is enormous. So, as a result of that, we ended
up with a lot of sonar images. We wanted to map out the rancid ideas, to
say to ourselves: There are Posidonia meadows there, there is sand here. So we collected these kinds of images. This is a real map
of Posidonia. We have completely mapped the Posidonia. There, if you want, I can show you
exactly where you dove with Sébastien. There is the port of Beaulieu. They were right here,
in this area. Do you know all
the areas by heart? Exactly.
It is mapped to the nearest 10 centimeters. It is said to be very accurate. What you see here are those famous
scars in the Antres herbarium. There we see them, it’s incredible. We were here. The idea is to say: Since
the problem is that, in general, people drop their anchor because they don’t
really know where they want to be , we have to show them what’s
happening under the boat and tell them where to anchor. So we invented Donia,
which is an application. We talked about the application.
Exactly. Which is available on phone,
tablet, Android, iPhone, whatever you want,
for free and which provides these very precise maps and which will allow
the user to come with his boat to position himself above the small patch of
sand in the middle of the Posidonia meadow. I’m going to download
this app. Donia, D-O-N-I-A? Absolutely, for Posidonia. Yes, obviously. That’s
not nothing. Look, she’s
downloading. It’s okay, there’s a network. So. Perfect. Thank you, Johan.
Thank you. I’m counting on you to talk about it.
It’s clear. Okay, see you next time.
Hi. I parked it where it was. So, which way is Paris? I have to hurry. I mustn’t miss my train. Hi, neighbor.
How are you ? Well, yes, but what are you
doing with a paddle? Wait, I’m on a mission
to the Mediterranean. Oh, yes, that’s right, I forgot. Well, yes, I met
some great people, eh. Some people replant posidonia. Do
you know what it is? It’s a plant.
They take it, hop, they transplant it. Then there are people
who repopulate the sea too. Well yes, with fish.
Downright. With 2,500 fish per year. 2,500 fish per year?
It’s crazy, right? Yeah, with everything we fish,
with everything we eat. It’s bubitia, right? No, it’s good, right? Okay, good. Well listen, well good
luck with your mission, eh. Okay, go.
Come on, see you soon. Is that really what happened? Yes, that’s really what happened. And besides, when I got back
to the saddlery, I had to clean Ah, the straps and everything.
Hi. Ah, well, you’ve come at the right time.
Ah good ? Come listen to what your daughter says.
What does it say? Well, you’ll see. Can I be happy? No, but I have to tell you. Today, you see, I had horse riding. First of all, I didn’t want to because
it was raining and cold. So we went,
there was mud everywhere. And then, at obstacle four, I got
hit in the face by a branch. And when I caught
the branch, I fell… I mean really, the glass,
it was this close to my head. I almost got hit,
and Carabelle just ran off, jumped the fence. 2,500 fish is not enough. What does the neighbor know about it? At the same time, now I have doubts. There you will have to pay €4,000. Are you okay, are you going to pay the €4,000? Yes, that’s it. Are you paying?
And well done. Check.
Congratulations, my dear. Keep it up, it’s very good.
Are you sure? This is very, very good.
No, but are you really okay? That’s what we’re going to do. I know. I think he’s going to I’m
sorry about your father. Is he sure what he says? I know. I know what I’m going to do. So, perhaps to convince
scientists, we need to show them how
beautiful the Mediterranean can be. And also to see scientists
to show that all this makes sense. So, I think I have
the perfect place for that. The Cerber Banyuls reserve. Come on, I’ll pack my things and we’ll go. Oh, Xavier! Oh, Paul! How are you ? So, how are you doing? Very good, and you?
Nickel. And it’s still beautiful here.
This is the south. Look, the sea is calm. 25 meters of visibility.
Oh yeah? Yeah.
There, we’re going to have a great time. Of pure condition.
Here we go ? Come on.
What do you want to see? I don’t know, strings.
Come on. Come on.
Some merons too, a little? Oh well yes, but
we see that often here. There are a lot of them. The last
count was last week. Oh yes ? There are two pairs of triggerfish
that have been observed all summer. Ah good ?
It’s magnificent, enormous. This is the first time.
Well yes. And like what, every year, But we see a positive change.
We cannot talk about the reserve effect. Exactly.
Come on, on stage. So Xavier,
where exactly is this reserve located? So the reserve begins
at Cerbère, more precisely the village of Les Alpes
which is opposite, and the northern border is at Bagne-sur-Mer. Okay, OK. So, what’s it like for you? Have
you been looking at this reserve for twenty years? That’s it, I’ve been here for 20 years,
living in this beautiful reserve. France’s first marine reserve.
Oh yes ? What year?
74. So, it is a reserve which is
extraordinary. Every year we see an improvement
in the species in quantity and size of fish. Lots of grouper. Last count, over 600.
600 grouper, there? Yes. Everything is big, actually. The crows are huge. We have huge teeth. Yes,
in fact, it’s a fauna that is much, much larger
than outside the reserve. So,
how many diving clubs benefit from this reserve? Here on the coast, there are 15 of us.
15 clubs? All right. And people, do they come more to see
the animals or more to pass their diving level?
There is everything. There are people who come to pass
the level and who will combine business with pleasure, since it is the reserve.
We have good visibility. They come to see fish. Rather than doing a diving level
in a pool or pit. It’s still more pleasant. And so this reserve
has immense economic benefits. Yes, the economic benefits are quite
broad, because it’s not just the diving clubs that benefit, obviously. Someone who comes to dive,
they may come as a couple, but they come as a family.
So there will be four or five of them. So, these people need to be housed,
they need to be restored. They might buy some souvenirs,
go for an ice cream, or have a drink on a terrace. So actually, it makes a lot,
a lot, a lot of people work. Well, that makes me want to dive in there.
Here we go ? Let’s get equipped and go.
Oh no, you’ll see, we’re not going to equip ourselves. To equip myself, I have another system.
Give me your hand. Trust me.
Go ahead. Are you ready?
Of course. Oh man, I hope I did
n’t forget my swimsuit. Okay, Philippe L’enfant,
marine biologist, where are you? I hear you’re built like a Goliath. I should be able to spot you from afar. Ah, there he is. Oh yeah, I’m going to
look tiny next to you. Hi Philippe, how are you?
Hi Franck. How are you ? So we’re going to count
the juveniles, right? Yeah, today, uh,
juvenile count. How is it going? Well, it’s pretty easy, right? This is called
visual counting while diving. So here, we’re not diving,
we’re snorkeling. So not the mask you beat. There you go, not the mask you’re beating. And the special thing
is that you can see on the plate, I have a layer with the coastline. And so I will follow
the coastline to identify the fish that will be present. So here, we are working specifically
on one species, sarcomin. And so, I will be able to note
as I go along the number of individuals who are present. You note directly
on the plate what you see while diving. Directly. You see, the pencil marks
very well on the plate. But what’s more, the special thing
is that I have templates to help me find the right sizes, because underwater,
it gets bigger with the mask. And there, the idea is, for each individual
that we are going to meet, I note perhaps three individuals of 30m who
were accompanied by two of 20m. Where do you note?
Directly on that? Directly on the plate. So, we have a codification which is quite
simple: the number, the size And like that, afterwards, I do my recap once
the dive is finished. Okay, well, come on, let’s go.
Come on, let’s go. Is it there? Yes, the boat is there, the equipment
is on board, so there is more later. Here we go. I’m exhausted. I’m not unhappy
that this thing is over. So Philippe, there, we saw
lots and lots of juveniles. So, I admit that I ca
n’t really recognize them. Have we seen any sarcomin? So, yes, there were
quite a few different species. In terms of sarcomin, there
wasn’t a lot of it. In fact, it’s a
rather low-number year. I’m telling you this because I’ve been
doing it since 94. Oh yeah, that’s…
That’s almost 30 years. It’s huge.
So it’s huge. But it’s also in relation to these 30
years that I now understand a little better how it works. And you see, for example, this year,
I think there must be 600 individuals over 20 km of coastline. The worst year
was 250 individuals. There, it was really… The numbers were very low. And on the other hand, we have had years where we have had
very large numbers of staff. It rose to 5,000 individuals. But that only happened three times. 5,000 individuals, in fact,
is not a lot. I thought it was millions. No, 5,000 is huge for a species. And for the 20 km. In fact, the millions are more
at the level of eggs and larvae. There, in fact,
there are millions of eggs that are released, millions of larvae that are
dispersed in the water masses. Except that, in fact, what you need to know
is that there is an enormous mortality rate. There is almost more than 3 million
percent natural mortality. We did a calculation,
out of a million eggs and marbles, we only end up with 15 that
complete the life cycle and reach reproduction.
It’s nothing. That’s why we need
this large quantity. But we are more in the
final phase, when we observe juveniles in the natural environment. So it’s normal that we rely
on figures that are of this order. All right. And so, we made this observation
in the reserve, we see more of it. I imagine juveniles in a reserve. No, not necessarily,
because most of the reserves were created 30, 40, 50 years ago. And at the time, we had this knowledge
about the ecological functionality of the loot, the nursery role. And in fact, we see that we have between 5
and 10 percent of nurseries that are in the marine air. And outside there are some too. So, now that we know them,
if there are future reserves to be created or if there is an extension like there,
on the Banque de Mouns, we are talking about a marina extension,
well it would be interesting to take into consideration the fact that, well,
in such a place, there is such a haberdashery that should be protected. If you had any wishes,
any things you still need to do to move in the right direction, what would they be? In the Mediterranean, I think there are 10
species whose life cycle we know a little about and we remember everything. We should increase the number of species,
especially coastal species, because they play important roles. And then they are,
at the coast, there are fishermen. There is the line, there
is everyone, there is enormous pressure. There is an urgency to act too.
Yeah, yeah, yeah. Maybe it’s time you went to
work a little after all. Ah good ?
There I prepared the leaflet. Oh yes, I see, it’s brand new.
Yes, she’s all… She’s a virgin. Plus, I gave you the sector,
so you just have to leave there? There, OK. Do
you see where Catalonia is? Yeah.
The border. Listen, come on, let’s get to work, eh, Franck.
All right. Well, thank you, thank you Philippe. Should I call you when I
‘m at the border? There you go, yeah, we do it like that.
Come on, let’s go. Hi, huh.
Come on, good luck. Come on, good luck.
Come on. I’m lucky, she’s good, huh.
Yeah. Up to the border. Is he serious? Come on, see you later, eh?
Here, we… It’s okay, it’s okay, don’t worry. Don’t worry.
I have the problems, it’s fine. At the same time, he’s so nice,
I can’t say no. Hi. It’s not next to the Spanish border. I caught the At the same time,
thanks to Philippe, now I know that releasing
2,500 fish a year makes sense. This is not insignificant. He can go get dressed next door. I hope what they gave me
at the pharmacy will give me a boost because tomorrow I’m having the re-sewing operation. I’m still doing hygiene with Andromeda. It’s a deep dive. I need to be in shape.
Come on. It’s located, it was a site
where there was pressure on it, a small impact during the construction of an
outfall, where suddenly, there was a release
of fines and particles which covered the coralligenous. And the coralligenous,
in this area, it’s a fairly limited area,
but the coralligenous is dead, because it was covered by the sediment. So we intervened to remove this
sediment and allow the larvae to develop. It’s simply
true that coralligenous grows around 8 meters per year,
so it’s very, very long. So, the idea we had with Écoséan
and Damien was to go and take species nearby
and we will come and reintroduce them on this site to help boost the creation of the coralligenous in a certain way
. Using a chisel hammer,
we will identify areas that have not been colonized on this coralligenous
that has been de-encevelated. And we’re going to make a small hole that will be
a few square centimeters to allow Damien’s support
to be inserted. We’re going to bring them back inside and we’re going to fill it
with epoxy paste so that it lasts over time. Because that’s
the idea, is that… It stays.
That’s what remains. Come on, let’s bring them.
There’s nothing left to do. We’re going to prepare them. It’s good. Corals are really
crazy creatures. An animal that looks like a plant. Apparently it can live super
deep, over 100 meters. The deep diving specialist
is Laurent Balesta. He lived at minus 120
meters for 28 days. Hey, come in, come in. Hi Franck.
Hi. Are you doing well ?
Very good, and you? Where are you from? Well listen, I was with Florian
and Damien on the replanting operation. Yes, you know? I wanted to go, I couldn’t,
but this thing is a great operation from the past. Yeah, that’s super impressive. And so, well, I had
a few questions to ask you. There is no problem. So, how does all this knowledge
that you have been able to have at great depths, at great depths,
also have an impact on protection? This question is always a bit
tricky. Knowledge of these deep-sea sites,
their associated biodiversity, and sometimes the functioning of these
deep-sea ecosystems can help when
establishing marine protected areas. So, if all of a sudden you discovered
that there was this place that is absolutely preserved, especially one that is very,
very rich, it is better to protect it there than right next to it.
Of course. Obviously.
And then create corridors too. Because I don’t know if there is a
refuge effect from the great depths that everyone would like to believe
that at the bottom, there is a reservoir that will come and reseed the rest. However, what is a reality
is that animals sometimes need several geographical areas
to complete their entire cycle. Places where they feed,
places where they breed, places where their juveniles live. And sometimes it’s not in the
same place at all. And this knowledge of
deep areas, as well as shallower areas , can help to say: It’s no
use protecting only there, if we don’t protect the place where they
feed, if we don’t protect the place where they reproduce. Obviously, this usefulness is undeniable. You need to know these sites well,
the biodiversity that you are associated with, to then come up with
protective measures. So, can you
show me some gems? Of course, that’s what I like to
do, anyway. And beyond showing jewels,
because often, we think that there are extraordinary animals,
you see, that is to say species. But it is more than species,
it is groups of species, that is to say an ecosystem. And then, one of our most beautiful
discoveries that is starting to be known now is this
black coral forest that we discovered. Is he white there?
It’s white, but do you know why? It is a sad observation. Black coral, which is all white,
is called black coral because those who named it are precisely
those who use it dead. Because indeed,
once he is dead and the living part, the flesh, is no longer there.
It’s the same, right? Underneath, it is a horny, black skeleton. And if you polish it, it becomes shiny. It’s very, very beautiful. And that’s not far away. It is off the coast of Assiota. We discovered it
14 years ago, I think, the first time we dived on it, it was at 75 meters. So, it’s still deep,
but it’s not extreme either. It’s not 140 meters, it’s
not 78 meters. Do you think I would be able
to go see that? It can be learned. Today, rebreather diving
is democratized. Yes, you can learn.
We must remain cautious, of course. It’s deep, you have to respect it. I can train myself.
Downright. No, today it is
completely accessible. Okay, Ben, here we go. Well, I encourage you to do it. Thank you very much for having me.
That’s cool. Well no, no, it makes me happy, you know. Well, I’ll give you
some news about the sciotta. That works. See you
soon. Hi Laurent, thank you very much. Have a
good dive, be careful. Yeah, it works.
Hi. Well, I have to find
a place to make my conclusion here. She’s pretty, the Sciotta, but… I know I’m going to ask myself
Ah well, that’s perfect. Alright. So, uh… Well,
all these people I saw, who are fighting for a better
Mediterranean, it did me good. Good because it changes the
mood, it changes all the media that keep announcing
disasters, that the Mediterranean is dead, that it’s ruined.
Said: Well no, no. All these people fighting, it works. And that’s good news. Hi François. Oh Pierre, hello. Well, you’re in luck,
you’re kind of the man for the job. I am in the process of drawing a conclusion
about, well, all these actors who are fighting for a better Mediterranean. Maybe it would be interesting
to have your point of view. Oh yeah, we could talk about it, gladly.
Come on, go ahead, sit down. So what can we
say about the Mediterranean? Is she feeling better? Well, Franck, remember,
more than 40 years ago, everyone, scientists,
then all the people who work on the Mediterranean, were predicting the death
of the Mediterranean within 10 years. Well, today, it is clear
that the Mediterranean is not dead. She’s better.
She’s better. And if she is indeed better,
it is because in the meantime, we have worked, we have toiled. So look,
we have improved sanitation, we have created treatment plants,
we have created laws like the Coastal Law, which has made it possible in particular to protect
coastal urbanization. To legislate the uses a little too. Yes, regulations had to be put in place and
enforced. We have created marine reserves,
we have improved knowledge, we have raised awareness among people. Which ultimately means that,
compared to a situation that was considered lost in the short term,
this is ultimately not the case. And so it’s important to say this,
to find this dynamic and to say that ultimately,
when we start working on a subject, even if it’s complicated,
even if it’s difficult, even if we think we have little success,
the fact of moving forward, of working, makes things better. It can work, but you
have to keep working. Yes, so if the situation has improved,
it doesn’t mean we have to stop working. So today, we have to manage other
issues, but we have many more resources,
many more technical resources, many more financial resources,
many more human resources. People want to protect
this Mediterranean Sea. Of course. So, if we managed to escape from a
desperate situation 40 years ago, with far fewer resources,
what is stopping us today from hoping to continue on this path
and make this situation even better? In fact, it is the combination of all these
dynamics that creates a positive dynamic. Yes, indeed,
when you have had success, when you manage to win victories,
it encourages you to make even more efforts and to create synergies
with all your partners. So, in fact, there you go, we have won
some battles, but the fight continues. The Mediterranean is not dead,
it is not about to die. See you soon. Well, there you have it,
I have my conclusion. Thank you Pierre.
My pleasure. So I really want to see
this deep Coraligene at 120 meters. I need to train myself. Are
you coming with me? Oh my!
Okay, come on, I’m going. Where is Laurent? It’s good ?
You have to train me. The Mediterranean. The Mediterranean. I know. That’s not a bad title,
guys, is it? The Mediterranean is not dead. It’s good. I hope it’s going to be a good movie. The world of silence is screaming. Enough is enough, man. When you see images of the oceans,
you think of your turquoise vacation with white sand. But it becomes the zone,
it’s survival under the sea. Just dig under
the hidden part of the iceberg. Between oil spills and massive fishing. Crazy enough to create
continents of plastic. You’re playing the fool with
your solid gold yachts. Damage not reimbursed
by MAF or change that. The world of silence shouts,
before it is too late. I’m fed up, big guy.
