Zoé and Eliott in the heart of the mystery of salt harvest

Previously in At the heart of the mystery of the cusse of the coussouls of Crau :

In the Rose of Crau Poussouls. Furthermore, Zoé absorbed theenergyenergy of life. Nevertheless, Men, animals, plants or even microorganismsmicroorganisms : Life exists everywhere and maintains the balance of ecosystems. Similarly,

More than a step … Think Zoé smiling. Meanwhile, Then, the ground begins to tremble, Zoé will be able to find her brother. Furthermore,

When Zoé finally landed on firm land, she does not understand. Furthermore, Eliott is not there. Nevertheless, Instead, there is a turquoise blue lagoon and coconut palms. Consequently, Further on, Zoé sees agricultural land. However, Everything is beautiful. Similarly, But Eliott is not there.

– Uh … For example, BIP-BOP? Nevertheless, zoé eliott heart mystery salt new Where are we ? However, And why is Eliott not zoé eliott heart mystery salt there? In addition,

– We are currently in Mayotte, the 101st department of France. In addition, Normally, Eliott is not supposed to be very far … For example,

BIP-BOP does not have time to finish his sentence, he is quickly cut.

– pssst …

Zoé looks to the right and on the left. In addition, Person. Consequently, But the noise resumes. Meanwhile,

Zoé details the landscape and notes a tuft of hair exceeding a rock. Moreover, He’s there! So, Zoé runs to join Eliott and take him in his arms. For example, Finally, they are united. Nevertheless,

– What happened, tell me! Furthermore, said Zoé.

– I arrived, all alone. Consequently, I was lost and petrifiedpetrifiedso I hid here for a long time. Furthermore, Then I met a resident! In addition, He zoé eliott heart mystery salt new told me that we were in the commune of Bandrélé, in Mayotte. Similarly, Salt is zoé eliott heart mystery salt harvested here! Nevertheless, Follow me, I’ll show you.

Eliott takes his sister by the hand and trains her on an earthcate. Therefore, After a while, Zoé stops: there are trees in the water!

– Me too it made me weird at the beginning, laughs Eliott. In addition, These are mangroves. Therefore, Trees. Therefore. Similarly, shrubs develop here, in very specific conditions: the waters are rich in salt and the ground is soft and unstable. Meanwhile, Additionally, Therefore, They are just in the area of tidestides : water arrives or leaves. For example,

– But how do they grow here? Nevertheless,

This time, Bip-Bop takes the floor. Similarly, He explains by turn signally. Moreover,

– The mangroves develop a seed on the tree. Consequently, If it falls zoé eliott heart mystery salt new into the earth, it is immediately rooted. Nevertheless, But if it falls on the water, it floats until it is too heavy. Meanwhile, zoé eliott heart mystery salt Moreover, At that time, she flows and takes root. Similarly, And, thanks to SoleilSoleilplants grow. For example,

– How so ? Nevertheless, Ask Zoé. In addition,

– It’s photosynthesis! Nevertheless, exclaims Eliott. Therefore, The stems and the leaves of the plants consist of small in the bodiesin the bodies named chloroplastschloroplasts. Nevertheless, They contain chlorophyllchlorophyll green that captures the lightlight sun. Thanks to this light, water and carbon dioxidecarbon dioxide turn into glucoseglucoseand sucresucre zoé eliott heart mystery salt new Important for plant growth!

– But how do you know all that? said Zoé looking at Eliott with big eyeseyes.

– I read zoé eliott heart mystery salt it in a book last year! Smiles Eliott, proud of him.

– Today, the mangroves are threatened, especially those that are less exposed to the tides, adds Bip-Bop. In general, there are fewer and fewer forests on the island. There is therefore a decline in the biodiversitybiodiversity Like Mayotte’s black lemur, one of the island’s symbols.

Then Zoé and Eliott continue their way. A few minutes later, they arrive in front of small constructionsconstructions traditional in boisbois. Women are busy just in front of them.

– These are the Mama Shingo, or the salt mothers, pronounces Eliott. Here, these women perpetuate zoé eliott heart mystery salt new a traditional know-how: harvesting salt.

– And how do they do it? Ask Zoé.

– At low tide, they collect a mud ofclayclay and sablesable called the limonlimonexplains Eliott. This mud contains salt and other elements mineralsminerals. Then, the Mamas Shingo filter this mud several times until you get the brinebrinesalt water. Then salt water is heated to feufeu wood. So the water evaporates and the salt can be recovered. The salt obtained is extremely white and rich in zinczincin ferfer and in magnesiummagnesium.

– This method is unique, underlines Bip-Bop. It is inherited from an zoé eliott heart mystery salt new ancient tradition and transmitted from mother to daughter. Elsewhere, we rather use the natural evaporation of sea water to harvest salt.

– That’s to say ?

– I’ll show you, said Bip-Bop.

Suddenly, Zoé and zoé eliott heart mystery salt Eliott are sucked in by the machine.

When Zoé and Eliott land, they are in the middle of immense rectangles filled with water. Some people are standing and work between the pools.

– This is where Guérande salt is harvested! exclaims bip-bop.

– Oh, it’s the salt we have, at home! said Eliott.

– It’s possible! This salt is very widespread, replica bip-bop. Thousands of years ago, the area was flat with a few holes. And since we are close to the ocean, the area was sometimes covered by water during the tides. This water brought earth, sand and above all … clay.

– Clay? Repeat Zoé with his eyes wide open. zoé eliott heart mystery salt new

– Yes, rivers or rivers that throw themselves into the ocean transport clay particles. These often fall back to the bottom when the water is calm, and in this area …

– The water was calm! Complete Eliott.

– That’s zoé eliott heart mystery salt it! There is therefore a thick layer of clay which makes this soil waterproof. that is to say that the water cannot pass.

– And what is it for? asks Zoé by observing the basins all around her.

– By staying in the basins, the water evaporates, known as Bip-Bop, mysterious.

– How does it work, evaporation? Eliott request. I know that above 100 degrees, water becomes steam but does it also work below 100 degrees?

– This is where it becomes complex, said Bip-Bop. In fact, the water is made up of many moleculesmolecules. Above the surface of the water, zoé eliott heart mystery salt new some molecules turn into a water vapor. When there is ventventthe water vapor is moved and other molecules escape to take their place. They are moved again by the wind and it continues! The more hot it zoé eliott heart mystery salt is. the more the molecules escape and turn into a water vapor.

– Okay, so in fact, water always has a small layer of water vapor just above it, zoé summarizes. So when it is moved by the wind. a news is created again and again until there is no more water.

– Exactly !

– But why is it salt left? Ask Zoé.

– Salt is a solidsolid Dissolved in sea water, Eliott explains to his sister. When the water evaporates, salt crystallizes and solidifies again.

Zoé and Eliott observe the salt dunes formed by malaria. They don’t zoé eliott heart mystery salt new believe their eyes: This salt is the one we use to salt our food at home …

– Look, said Bip-Bop. Malaies collect different types of salt. The thinner and delicate flower of salt is formed on the surface of the water. At the bottom of the basins, the zoé eliott heart mystery salt coarse salt is formed.

The gestures of the malaria are meticulous and technical: they perpetuate an old know-how.

– But besides, why are the sea and the ocean salted? Ask Zoé.

– About 4 billion years ago, there was no water on earth, but there were many volcanoesvolcanoes. They released a lot of water vapor and others gazgaz in theatmosphereatmosphere. Later, the earth has cooled and there were abundant rains. These rains will have two effects. Of one, they zoé eliott heart mystery salt new carry with them part of the gases of which chlorinechlorine. Of two, they flow from the rocks and take their mineral salts, including sodiumsodium. Chlorine and sodium accumulate in seas and oceans and form sodium chloride: salt.

After some time. zoé eliott heart mystery salt Zoé and Eliott see many speciesspecies who live in this preserved and fragile environment. An leanher heron is placed there, motionless and majestic. There is also Saline toolypelle, a small algaealgae rare and threatened worldwide.

Passing near a salt dune, it starts to shine very hard. Zoé then presses the blue button and a dazzling light escapes. Zoé and Eliott only see this light which takes up more and more space. As if by magic, it is sucked in by zoé eliott heart mystery salt new the machine and the inscription is displayed: 7 / 7.

Zoé and Eliott are happy and proud to have arrived so far but a question remains unanswered …

– BIP-BOP, starts Eliott. Why was I taken so far from Zoé?

– Ah, that’s because the machine found you a little sad.

– It’s true that it’s been a long time zoé eliott heart mystery salt since we are separated from dad. mom … said Eliott. But why did you do that?

– For you to take advantage of the sun, explains Bip-Bop. In the presence of light, our body produces hormoneshormones called endorphinsendorphins. They reduce the painpain And make us feel good. Another hormone is also released: the serotoninserotonin. And you know how we nickname it?

Zoé and zoé eliott heart mystery salt new Eliott shake their heads: they don’t know.

– The hormone of happiness! Exclaims Bip-Bop by flashing. If we don’t see enough light, we can have little blows!

– Wow, so the sun makes us happy? request Eliott amai.

– We can say that, yes, confirms Bip-Bop. It also provides us with a dose of vitamin D. They are important for the functioning of cells and zoé eliott heart mystery salt fixing the calciumcalcium On the bones. But beware, always apply sunscreen so as not to take sunburnsunburn : They can be dangerous.

– And the energy we have just recovered? in turn questions Zoé.

– It’s solar energy, said Bip-Bop. The sun is very important: it lights us, heats the earth and allows the presence of water liquidliquid. The sun allows us to harvest salt, make zoé eliott heart mystery salt new us happy and to carry out photosynthesis. But above all, without him, life would not exist.

Zoé and Eliott do not come back. All the elements they have recovered are necessary for the proper functioning of the planet and life.
