La révolution des algues
Considérées à tort comme une pollution dont elles ne sont que le symptôme, les algues nous offrent en réalité un champ d'innovation infini et des solutions concrètes pour répondre aux grands défis de notre époque. Si nous apprenions à les cultiver de façon durable, elles pourraient nourrir les hommes, se substituer au plastique, décarboner l'économie, refroidir l'atmosphère, nettoyer les océans, reconstruire les écosystèmes marins, nous soigner et fournir des revenus aux populations côtières... Les algues constituent sans doute la plus importante ressource encore inexploitée au monde. Premier maillon de la chaîne du vivant, elles communiquent entre elles, se reproduisent et poussent très rapidement. Elles n'ont besoin ni de nourriture, ni d'eau douce, ni d'espace terrestre, ni de pesticides. Aujourd'hui, la surpopulation et l'urgence écologique nous conduisent à appréhender avec un oeil nouveau ce trésor oublié. Voici 12 000 ans, l'homme est sorti de la préhistoire en cultivant les végétaux sur la terre. Renouer avec ceux de la mer sera une révolution pour notre civilisation. Une révolution des algues !

June 20, 2024The writer is passionate about his subject. Unfortunately he is prone to unsupported and vague sweeping statements.
For example, in chapter one:
"The number of dishes is a clear testimony to these traditions originating from this first human migration" is unsupported: it's correlation not causation.
"Our planet no longer has much accessible and unused arable land." has no reference, no comparison, no numbers, emotionally it feels accurate, but objectively it's useless.
"10 grams of the abundant sea lettuce (Ulva) is enough to meet our magnesium requirements. In this respect, it is much more natural and efficient than chocolate and contains no fat or sugar". This time there isn't even a correlation. No one, literally no one, eats chocolate for its magnesium content.
"It's not hard to imagine which part of the world has gained the most weight" has nothing to do with seaweed, it's just putting two unrelated things together and pretending there's a connection.
"Demineralized water costs nothing to produce in this scenario, but can be sold wholesale for a few dozen cents". A few dozen cents for what? a ml? a litre? a gigalitre? a small lake?
The bit on umami and MSG is just weird ("An almost primal taste; breast milk is rich in umami.")
Also, phrases like "our side of the planet" are alienating. Your side ain't my side (I live in Australia).
And his understanding of Asia is confusing, for example:
"Asia has been, and remains, influenced by traditional Chinese medicine". Does he mean China does? Pretty sure other parts of Asia (such as India) have their own long histories of traditional medicine.
"[Seaweed] is to Japan what bread is to France" is another sea lettuce/chocolate situation: surely the Japanese equivalent to the white, starchy, delicious carbohydrate of France is rice.
The author is upset that the iodine threshold that is deemed safe for human consumption in western countries is much lower than in Asian countries, but in the middle of the argument he says:
"Asians have developed a specific microbiota capable of absorbing substances found in seaweed, including iodine" ...
So it makes sense that Asian countries have higher safety thresholds, it is not "more astonishing", it is more logical!
I will try to keep reading, because I am very interested in how we can harness our oceans to battle climate change and feed the planet, but I was looking for facts, not impassioned rhetoric.

Absoluut een aanrader voor iedereen, al is het maar om een positief en hoopvol boek ter hand te nemen (dat doen we te weinig). Verder is het een goede kennismaking met wieren, (de geschiedenis van) hun cultivatie, de huidige teelt en de vele toepassingen — sommige realistisch, andere nog toekomstmuziek.
Ik moet eerlijk zijn, de introductie voelde wat ongenuanceerd. Maar later komt de balans terug, en juist die latere hoofdstukken vond ik het sterkst. Zeker de moeite waard.

this book is AMAZING and so so so so good! i read an exerpt in a magazine early last year, and I was SO excited for it to come out. I'm very slow at reading nonfiction, so I only just finished it after starting in November (whoops) but it was so great and I'm so glad I finished it when I did! it tied into so many different ideas and topics I learned about in my last semester, and having that knowledge made me appreciate what I was reading so much more! but this book is very accessible and you don't need to have a background in the subject to understand what the book is discussing! the only downside of this book is that my friends and family are absolutely sick of hearing about seaweed, but I'm too obsessed to stop talking about it anytime soon. this book is instantly a favorite for me, and I'm SO happy that i read it!!!!

Seaweed is going to revolutionise the world
1. Seaweed foraging allowed human to reach America through the Pacific Ocean, new archeological evidence showed
2. Seaweed provides vitamin C and would have saved many sailors’ lives before citrous fruits; it provides iodine which cures cretinism
3. Seaweed is regularly eaten as food in Japan and Korea, but China is number 1 exporter
4. Seaweed has antibacterial and antiviral properties, including Covid
5. Some seaweed helps with Alzheimer’s
6. Seaweed makes agar-agar (vegetarian jelly), agar Petro-dish, constituent in toothpaste, face masks
7. Seaweed planting can capture all the excess phosphates and nitrates from industrial fertilisers, and harvested before they form green/red tides; China is already doing it
8. Seaweed provided ecosystem for crabs and sea cucumbers
9. Seaweed can be used in bricks that can withstand earthquakes and typhoons

This is a very easy, pleasant and interesting read, though not a very scientific one. It tries to make things sound more amazing, when they would be interesting enough without resorting to hyperbole...
He says more than "50% of oxygen in the atmosphere comes from the ocean, and therefore algae", which can be misleading when he's previously talking about seaweed, in a book about seaweed... Algae include microalgae, which produce the greater part of that oxygen, together with cyanobacteria. Seaweeds' contribution is very small.
Seaweeds can't communicate with other species, and attract predators when they are attacked by snails, as he states in the introduction. The snails attract the predators by being there... (Also, no reference there)
Later he states that in Japan, seaweed accounts for 10% of daily nutritional intake, and offers a reference. The information is both not true and not in the paper. The paper cites other studies which evaluate seaweed consumption to be between 4-12g/day. Hardly 10% of dietary intake...
The paper, about iodine intake, states intakes in Japan are 15 times above what is considered healthy in Europe, because through traditional consumption their gut bacteria can break down iodine (which would otherwise cause thyroid problems (so we, non-japanese, cannot, in fact, increase consumption by that much)
This could be a great book if it were stricter to facts. It is an easy read, but has to be taken with a grain of salt.
As I'm reading, I feel the need to constantly fact check, so I see no point in continuing reading..

EVERYONE NEEDS TO READ THIS BOOK!!! Gave me so much hope for the future in terms of climate change initiatives and so much inspiration in my own life at how I can better myself and be more environmentally conscious and make a difference.
My major outtakes are:
Seaweed forests could significantly reduce methane and carbon dioxide outputs which would result in both short and long-term climate change action.
To encourage the production of seaweed forest we need to all invest more in the seaweed industry- eat more seaweed, use seaweed plastics/ seaweed soaps etc. etc.
All kinds of seaweed are edible lol (everything u find on the beach)
If you ever get stuck at a desert island kelp naturally desalinates water so just spin dry it and you will have access to fresh water 😇
Can’t put everything I’ve learnt into enough words but please please please give it a read. So nice that it’s a positive and hopeful perspective on combatting climate change and working with the planet and each other :))

Fantastic introductory and incredibly public-friendly book on the intriguing, practical world of seaweed and its applications. Would have had 5 stars if it discussed more about algal biodiversity and its ecological functions, but great nonetheless. Everyone should read this book to expand their outlook on a very brushed over thing that is all around us, and is part of our future.

Informative and interesting projections
Covered the markets well where seaweed can play an integral role. An optimistic projection for the future and give us all hope.

Ce livre offre une véritable ouverture sur le monde des algues, un monde aussi fascinant qu'inconnu du grand public. Vincent Doumeizel montre les perspectives réjouissantes que peuvent nous offrir les algues tout en expliquant les difficultés et la rigueur qu'il faudra pour les cultiver sans endommager les écosystèmes.

A beautiful about seaweeds and humans. Having spend a lot of my life studying seaweed, I can definitely recommend this positive story on how seaweed can help us to tackle some of the important challenges we face. Is seaweed gonna save the future? No. Can it help to save the future? Yes. That's why you have to read this. Five stars.
