Food production is facing challenges that require new, more creative and sustainable solutions. Companies involved in various segments of the industry, including agriculture and fishing, are looking at revolutionising the current systems, which have left bodies of water overfished and land in terrible condition.
On Long Island in New York, locals are tackling overfishing by using a new system that brings industries together. Fishermen and scientists have collaborated to realise and improve 3D farming.
3D ocean farming is a system that grows a mix of seaweed crops and shellfish – including mussels and oysters – under the water’s surface. This polyculture vertical farming system requires zero input because the sea plants filter and sequester carbon, making it, at this moment, the most sustainable means of food production on the planet.
“Imagine an underwater garden where you’re using the entire water column which means we have very small footprints,” tells ocean farmer Bren Smith.
Additionally, this system also sequesters carbon and rebuilds the reef’s ecosystem. The crops and shellfish grown underwater can be used as food, fertiliser, animal feed and even energy. In this way, climate change can be tackled while producing food, i.e. the food itself is the water filter.
“[mussels are] really lean proteins packed full of omega 3s, but also soak up and use nitrogen to grow… this farm filters millions of gallons of water a week and oysters filter up to 50 gallons a day,” Smith says.
“We have to tell a story, a helpful story about the future. You know, it’s all bad news about climate change and food security. I think out here we can say our oceans are a blank slate and we really have a chance to really build something new, and build something from the bottom up that’s sustainable and restorative and doesn’t make all the mistakes of industrial agriculture or aquaculture,” Smith explains.
These videos give us hope, thru reporting on actual solutions that could be emulated by other countries and communities worldwide.
Keep up the good reporting, Al-Jazeera English!
@Northern85Star u have evidently not done any scientific studies in ur life the people studying this know a lot more than you do you imp this is good journalism by aljazeera and you are just being a pessimist aka waist of space, you are unnecessary to human betterment only hope solves problems and determination not idiots like you.
H Bensaude Oh my, a parrot. Well, you are not going to be able to understand this, but i will give you a hint that you will not accept out of prejudice and indoctrination: “science” does not care about nature, science cares about society.
Do some research boy. Get out in nature. I am typing this on day 4 in the wilderness, city boy.
I dont know what is worse: that people who pretene to understand doesnt or that this had become a trend among people who are completely out of touch with in and 100% part of the problem due to their lifestyle – yet they themselves do not think so.
There is nothing pessimistic about being realist if the future in this perspective is going to be destructive. Stop lying to yourself.
@Northern85Star this is a very interesting advancement in ecology i don’t think you should be questioning or assuming where i live (i live in the countryside in England) and i have been studying sciences for the last five years. i believe that ailazeera has done a good job to make this understandable for idiots like you but not enough scientific details i have read the scientific papers on this. and i believe the experimental data that they have shown is sufficient beyond you.
H Bensaude You have studied “science”?! 😂
I dont care what you believe, just remember this conversation in a couple of decades and weep as the “solutions” you believed in created new ecological balances.
Humanity is not smarter than nature. The problem is people who believe the opposite. People like you.
@Northern85Star that’s ok that you don’t believe in my education that you have clearly not had and I am sympathetic of ur case but if you don’t care about my opinion then I don’t care about urs just remember I am not saying science will solve everything I am saying science has the answers to solving most of the worlds problems it is just that humanity does not act on those answers. So of course humans make mistakes but nature does to eg when competition lacks useless and feable animals like the dodo are created also if u believe nature is better than capitalism then start by eating and killing all the animals you can find so that then only those that can survive aka the strongest will survive. I think you are on ur vegan moral high ground even though you don’t even know what natural selection is
This came from korea.
So did Herpes, what’s your point?
@Incognito Friberg The point is, this has been done in Korea and surrounding countries for centuries.
One can choose to take that information to adopt good habits acquired from centuries of repetition.
diving stuff are my favs. Cool.
If kelp grows in salt water, does the fertilizer guy use fresh water in his kelp breaking down process? Does he have to wash the salt brine off first? Can’t put salt water on veggies and expect them to flourish.
From what I have seen, a lot of kelp is dried, excess salt and minerals collect on the surface of the kelp as it dries and is typically shaken or brushed off before the kelp is broken down into smaller pieces.
You rinse in fresh water first then is soaks and rots in unsalted water in barrels running it through a grinder would vastly speed up the process.
despite being grown in sea water kelp and seaweed ingeneral has a lot less salt than you’d imagine. Still some, but mainly on the surface. You can just wash it off.
We should grow kelp in the dead zones to alkaline the water
Algea blooms from fertilizer run off and the water treatment from towns and cities they rot and reduce the waters oxygen content It would be better to grow single cello algae at the source and harvest it.
Government are to be blame if overfishing happens,only taking without giving is a recipes for disasters,while collecting taxes,nothing is reserve for giving back,by breeding and releases,open and close seasons,undersea landscapes,reef construction,mangroves farming etc,these healthy practices helps the fishing industries to survive,even kelps and seaweed farming helps,no fishing zones for rehabilitation and distribution.
overfishing = businessmen = capitalism. i dont like capitalism tbh since its a world paradise for rich
Seaweed is tasty! Have not seen it on a plate here in Latvia.
5 years ago, scientists (supposedly everyone respects these people) stated that the ONLY way to stop the decimation of our oceans is to, en masse, stop eating any type of seafood WORLDWIDE! That we as a world, were past the point of no return…so where does that leave us NOW?!?!
That was 5 years ago!!!On top of that, Amazon’s 2 Day Service is POURING CO2 Emissions into the atmosphere. (Google it)
These behaviors have NOTHING to do with governments but everything to do with personal responsibility!
STOP FLYING/DRIVING for any type of entertainment, vacations, bar hopping, movies, concerts, sporting event, etc. Movies use multiple vehicles and generators that pour CO2 Pollutants into the atmosphere, mostly because they SIT on set, IDLING!
STOP using Amazon’s 2 Day Service…use their business, just wait longer to get your merchandise.
It is easy to always blame governments and politicians because that removes personal responsibility! SO, governments won’t do anything, especially countries like China, Korea, India, Africa, etc.! So take matters into your own hands and stop EN MASSE eating any kind of seafood, driving for entertainment or anywhere unless an emergency!
How many people live within 10 minutes of each other but will not carpool?!?! Google this info! Find out for yourself!
The more we sit and complain without taking steps OURSELVES, the more we are just a bunch of hypocrites!
Either make changes or stop freaking whining! about it!
I remember they had a huge rally in NYC to make a big deal about climate change/pollution. Tons of cars drove into the city for it, garbage was everywhere from these people using petroleum based products (cups, food carriers, etc.) and then, AT AN ENVIRONMENT RALLY, they threw them all over the streets. Even DiCaprio FLEW IN ON A PRIVATE JET!!!
Holy cow, talk about ridiculous.
Meh, we just need some ocean seeding.
Malthusians/are always wrong that is why every ten or so years another doom prophesy must be issued.
Stop X is not a good way to reach to people who see themselves as removed from the climate issue.
Demanding cleaner alternatives is a preferable way to preserve our Earthly bounty as well as the stability of our financial arrangements,
either being jeopardized could have real catastrophic results for marginalized people.
CO2 is literally Plant Fertilizer, compared to the Jurassic era, we are in a massive CO2 Drought.
The higher the concentration of CO2 the Less energy a plant has to use to obtain it hence it’s able to grow faster, and up to several times faster if enough CO2 is available.
@DoctorDrizzle Dead right!!! Look at CO2 Planted Aquariums…they boost the CO2, the plants have explosive growth!
What is this 115 like? It is super low. Come on Google recommendation AI, you can do better.
Twins meet again: 9:37 😀

If mussels filter polution and eat polution, they will have abnormally high levels of mercury and other harmful toxins.
Not really, mussels are very low in the food chain. It becomes a problem with animals much higher in the food chain, like tuna. Eating too much top predators like that is a bad idea because they concentrate all the heavy metals collected by the entire food chain below them. It’s by no means so high that you should avoid tuna altogether, it’s tasty so go ahead and eat it, but you should not go crazy and make it a majority of your diet. Decades of eating top predator meat will add up to significant amount of heavy metals.
kelp has been used for fertiliser like this for beyond memory in parts of ireland and britain
In the US as well, but idk what that has to do with underwater farming
@Sho Yu Weeni it’s a revenue source
Where does one go to learn this as a business?
Where i am there are various aquaculture degrees/diplomas/certificates at tafe and uni like the tafe i go to in Fremantle Western Australia. i believe a degree in marine science could also be a pathway but with a much broader syllabus. doubling up and doing a business course couldn’t hurt either. Hope i was of some help.
@Bazaar31 thancks, it was
Go out, buy a boat and a farm fishing licence. Learn as you earn. Stop going into debt for stupid degrees.
Im actually doing marine tourism for a bit of fun/experience and as a way to earn money to invest in my own fish farm. Not sure if i’ll study aquaculture as a course or by my own research and just talking to people, possibly some volunteer or part time work on a farm. You are totally right there are many ways to go about it.
to answer his question though learning it as a business you are a lot more likely to make the connections and have a professional appearance with recognisable qualifications.
It’s 2019 how are companies still allow to dump toxic chemicals into the oceans like that?
@The Renegade Kautsky that is a Cop out, you might as well put your fingers in your ears and yell I can’t hear you over and over.
Barskor1 I’m just doing what you guys do. And it really is made up anyway.
The West is by no means clean. Go to other parts of the world. They are equally as affected by the Western invention of nation-state and the consequent boundaries of accepted economic activity. People still remember when the Hudson River was on fire. Besides that, the West exports trash in huge volumes on barges. This is not cleanly behavior.
@The Renegade Kautsky Can companies dump toxic waste into your lawn?
By no means is law made manifest from nature. Private entities can certainly violate your natural rights without a state and remain firmly within legal or ethical boundaries.
Please forgive me. Please approve me to share this clip in my Facebook group so my community can be acknowledged and perhaps take a leap towards

The answer is to find away to stop the cultures over populating without any regards .everyone knows who and where this is.
If you have over a billion people then your guilty lol
Dadson worldwide don’t worry Bill Gates is on it !
@DoctorDrizzle as soon as everyone can afford 8,000 toilets.
8:12 “You’ll never taste kale that tastes that good again.”
Yeah, that’s because kale tastes terrible, making it even tolerable to eat would be a major improvement.
pfuog P lol I’ve tried a number of ways but it always tastes bitter. I guess I haven’t found the right way yet
whisperingwind2 the healthier the kale plant is, the more chemical deterrent it is able to make and store in its tissues, which we perceive as a bitter taste.
Kale Doesn’t want to be eaten and die; Kale is trying to make it in this world like the rest of us.
Though this goes for all plants, with the exception of their ripe fruits.
Plumsmuglers I’m sure pigs don’t want to die, but bacon is delicious.
whisperingwind2 Right but pigs don’t excrete poison for defense they run instead, unlike a pig people can’t break down plant poisons very well, immune system just deals with the fallout.
So the question could be asked as to who’s exactly saying plants are healthier than animal meat?
Plants are what the failed hunter eats.
Plumsmuglers I don’t know who’ claiming plants are healthier than meat, certainly not me and seemingly not you.
I can say that I find kale to be disgusting, and would rather eat most other vegetables than kale.
Also, by the reasoning of your last statement, couldn’t it be said that meat is what the failed gatherer eats?
I don’t hunt, though I would, but I have fished and I have foraged. I have also raised chickens for meat and eggs and I normally try to keep a solid garden around for fruits, vegetables and grains. I’m neither hunter nor gatherer, but I love food.
When I make gross amounts of money, I’d want to invest in something like this to rejuvenate the oceans.
If government were not hyper controlling over coast lines you wouldn’t need to be rich to do it as all you need are a small boat buoys ropes and net sacks and some wild samples for base stock.
Get back in your paddock you Domesticated Animal !
Well, that’s a garden that you won’t have to water…That aside, thank you.
Keeping the sea cows out of the sea cucumbers is a challenge
Tommy has enough trouble keeping peoples out of his cookie jar.
Africans still can’t farm on land. Maybe they can farm the Sun?
Tom Meyers Concentrated Thermal Solar all the way Tommy Boy.
Farm the sun? Obviously you would only be able to do such a thing at night.
If you watch where fish defecate the ocean is a lot like San Francisco
Laughing at this idiot watering the guys farm with a watering can 😂
you know nothing jon snow!
Please let more people do this. We NEED to save our beautiful environment!
did you steal the background music from Banished (pc game)?
Problem is that sealife filters all the pollution from the sea.. and if you then eat it, its a problem. Fish etc. are basically already something you should avoid.
Kelps problem is its high iodine content, so you can eat it only in really small quantities.
do japanese have high blood pressure? they eat loads of the stuff
@Event Hʘriךּon I dont think they eat kelp.. kelp is especially high in iodine. You can literally eat like under 1g of kelp per day, otherwise you mess up your thyroid.
ISIS, Boko Haram does not approve! How will they go boom under water and get their 72 virgins? Not to menion the thousands of tons of Fukushima radiated water poured to the sea? What if these terrorists turn into zambies! Invasion of the zombie mutant terrorists?
The volume that this farmed kelp does nothing for sequestering carbon to fight “climate change”. Yes his halo effect does help the immediate area around it, but I highly doubt that humans would have use for enough kelp to farm it and change planet wide environmental issues they are complaining about. The earth will heel itself if we reduce the volume of pollution humans have put into the ocean.
Excellent Work,
Now what we need are 3D printers to print 3D Fish.
i love seaweed salad at my local sushi bar.
I love this
haha gtfo! we dont need more food! we need LESS PEOPLE!! the future is WAR!!!
We just need less government, not no government, just a more transparent governments with less power….
Fisher Of Men Cool story bro. Name a gov that started small and stayed small
2000 BC Asia: hm kelp taste good
2010 AD Western World: THIS NEW FOOD TREND CALED KELP
@Diller Hiller If you happen to visit a Japanese restaurant, the seaweed salad is from kelp. Kelp (brown algae) is one of 3 types of seaweed. There are tons of recipes in Chinese cooking about seaweed. Kelp has a very high nutritional value.
@Thomas Hung I know.
Positive vibes
@xinglin jiang have you found places to buy yet?
@Oyster Ninja Pc no. but i find free pacific oyster if you dont count the transport cost. they are really fat.
Why are we not funding this?? Oh wait . People want a wall . Smh
I always see documentaries and social movments uselss, people who can change reality for better are the same that are changing for bad, the exemple of that its people like Elon Musk, we need more people thinking in how solve this problem, not making laws to prevent those things to heppend…
Mtpimenta
Exactly, I have always thought this way, why are the good companies (environmentally speaking) are the one who should adapt to the economy while the who actually doing the polluting just run away with it.
3:12 ahoy!
…oh ahoy… *Under breath* wierdo…
I don’t hear the speech, only loud music.
How would land area be delegated in the ocean?
Same way it is on land they map it
Respect! Well-thought out project, nice to see that some people are not just thinking of themselves and fast profit, but of the general interest and future instead. This and similar sustainability and environmental projects should be mainstream not tomorrow, but today. Well done!
or you know focus on the cause of the problem, Animal agriculture waste run offs.
SOILENT GREEN IS PEOPLE!!!!!!
Sprays it then he eats it 😖😔
*goes and puts plastic net bags in the ocean😂😂*
They wont stay there
I know but it’s still funny
Does that mean eating shellfish is like eating pollutant from ocean?
I just find my future insurance job if lost my job
i will do this
The only fish seen in Dah video 0:43 & its dead 🤷♂️🥺👉🐰🍺🐨
here is something the farmer not telling the public, the shellfish(all) yes, filter out all the nitro but all also the pollutants and heavy metals in their flesh which you consume. so is that healthy, for the clams, muscles, oysters but not for people. the only good eating from this is the seaweeds.
But what about aquatic animal?
One big problem is that we only takes and never gives back to the seas,we needs breeding and releasing programs where Governments around the world participates,have marine conservation and off fishing timetables for sponging seasons,sizes limits and monitored fisheries.Unless we manages it well our future generations may not have fishes in our seas.
Scottish? Sexy
Whuzzin Gamont glad somebody bought that up.
Hes cute
Awesome video, thanks for posting
Yah blessem all
why would anyone eat an oyster that filters 50 gallons of water a day? all that nasty stuff has to end up in the oyster
The oyster converts that ‘nasty stuff’ into more oyster by digesting it. Sure some trace elements and chemicals end up in the meat, but no more than you’d find in any other seafood.
@Acsion42 good to know, thanks!
🤔 this all sounds good 🤔 but with Fuckedshima contamination of the oceans 😞 little to late 🙈🙉🙊✌️🌎🖖
out back so what are you doing to help?
You mean the bp oil spill in the gulf. Of Mexico not the fertilizer from farming . The oil spill is what killed the Gulf of Mexico
Alex Villarejo no, the dead zone existed long before oil spills. All the farms along the Mississippi River wash their fertilizer and runoff straight into the Gulf of Mexico. Research gulf dead zone
Will check sounds troubling one more man made problem in our ecosystem
This is going to become a Billion Dollar industry
WHAT A STUPID AMOUNT OF BACKGROUND NOISE!!!
CALL ME OLD FASHIONED , BUT I WOULD PREFER TO HEAR THE SPEECH.
So they finally started what Japan has been doing for years.
Absolutely fascinating. Hope this catches on. What an Agricultural revolution that would be!
im gonna do my part and order lol
Now this is a great way to use the sea
Great graphics explaining the underwater structure of kelp farms!! Also, the best news video on kelp farming I’ve seen.
Who you think will buy sea weed and mussels grown this way if they are grown / farmed in a toxic water? I won’t.
Mussels don’t take nitrogen to grow, they produce it in the form of ammonia… The kelp does absorb nitrogen in order to grow though
reichrunner1 technically, mussel filter the water from organic particles that may contain proteins which would have turned into…. nitrogène.
@Waxoff Waxon Right, and they in turn produce nitrogenous waste. I guess they sequester small amounts of it in their own proteins, but it’s really odd to claim that they are pulling nitrogen out of the water column. And any that they do consume is already organic matter. It’s not as if they are cleaning water of fertilizer runoff like this video was implying
to both individuals…. mussels are filter feeders. They consume mostly algae. For the mussel to grow in size, it must produce amino acids in the form of proteins. The principal component of amino acids is nitrogen. Since the mussel is such a fast growing shell fish, the mussel removes approximately 10 to 20 times more nitrogen than it produces from wastes. Mussel don’t sequester small amounts of nitrogen. Mussel sequester proportionately huge amounts of nitrogen compared to the rest of their body mass over the period of time it took to grow.
@Jason Masters Yes mussels (and all living things) need amino acids, and by extension nitrogen, to grow, they are not able to directly use ammonia for this purpose. Sure much of their food source uses ammonia, but that ammonia would be sequestered with or without the mussel. It’s the algae doing the sequestering, not the mussel.
As for your claim that mussels remove 10-20 times what they excrete, I find this extremely hard to believe… An animal generally needs far more energy to grow than it needs physical protein, so the idea that mussels grow 10-20 times faster than they respirate seems rather far fetched. If you have something to back that up, I’d happily read it. Just seems a bit extreme to me
@reichrunner1 sure… here’s some lite reading. The easiest way to research this is to go to ScienceDirect or Wiley or Springer to download the research papers. Or if you want, you can call one of the authors of the first reference, Gary Wikfors at the NOAA labs in Milford, Connecticut.

“Based on their study, the group estimates that a fully stocked raft would clean an average of 11,356 m3 of water and remove about 159 kg of particulate matter, like dust and soot, daily. In addition, when the mussels were harvested, 62.6 kg of nitrogen would be sequestered in mussel tissue and shell.”

overfishing has all but eliminated Blue Fin tuna and what the world did to all but kill off Sperm whales and other whales for their oil and Ambergris..
What the Earth really needs is less humans 🤷♂️
This is cool and all but we are reproducing far to rapidly and too much
I like this guy do not believe that the challenges of our time are too big for us to handle. There are little things we as consumers can do to help our environment. I have made it a point to drive less. We planted a garden in the backyard of our suburban home. We have a compost. We recycle everything we can. We use reusable grocery bags, when we remember them. In a few months we are moving because of my wife’s work and with the move we decided we don’t need as much living space as we currently use. We originally tried the Meatless Mondays but that turned into less meat Mondays. Now we are committed to reducing our meat portions and so far I am good with it. Our new home is in a condo community and I am hoping to start a community garden there and spruce up the area with a lot of flowers and a new tree every year. I think it would be great to have a community Christmas tree we could decorate as a community. We could make an event out of it with hot chocolate and cholaring.
I wonder if the Middle East has a “CNN Arabic”.
Mark N. Same but I don’t think they have an equivalent to cnn because there’s no sjws there or people screaming racism at everything that breathes
Well, yes… arabic dot cnn dot com
This guy lol he did another doco on fashion and de forestation good man
We need to do this in the coromandel we grow to many mussles an no kelp
Why would you eat kelp; it has like no calories.
I believe the solution is the charcoal.
Let’s mix it with the water and allow to sink in the water.
Biochar should absorb ANY dirty things….
Marvelous
great video
this is Great Content 🙏🏽😎👍🏽. Youngsters Should take up this Businesses. it is a Plus Plus for both vegetarians & non-vegetarians.
So Kelp is useful for a different reason than the culinary stuff they showed.
The real advantage of kelp farming is the rate at which it pulls carbon dioxide out of the ocean, because the ocean is already the largest active carbon dioxide sponge on the planet.
human over population…the massive problem of the planet.
