I'm surprised you didn't mention that certain seaweeds, if fed to cows even in small quantities, *drastically* reduce their methane emissions. So we can also grow seaweed as a feed supplement for cows to produce climate benefits.

We're already producing enough food to feed 10 billion people, but 30 to 40% of it is wasted through poor storage and food being sent to landfill. We need to work on that side of the equation while also looking at ways of reducing the impact of the food we do need to grow - that would be a double punch for feeding people and saving wildlife.

I wrote multiple papers for my degree on algaculture (both micro and macro) for sequestration. A proper carbon market would go a long way toward accelerating this industry.

I think a lot of it has to do with regulation. People love seafood, it's just expensive. Being able to reduce the cost of oysters significantly would get people interested in them. In addition to that, oyster shells contain a lot of minerals that can be used to create cement and concrete. There's a potential to create a secondary market for waste materials.

One option is growing seaweed as foodstock for cattle. Not a perfect solution, but an excellent stopgap option as we work on reducing the demand for beef.

Nice job! I like the idea of growing things that don't ruin the water, don't cause resistance in parasites, and don't result in seafood that is far less healthy than wild caught.

Seaweed farming could be used to provide chicken feed very easily and people wouldn't necessarily know the difference.

Here in the UK, we are an island surrounded by all sorts of wonderful fish and yet most will turn their nose up at kelp and shellfish. Getting schools to provide these as a healthy food option is probably the best way to change culture.

Logistics is also a concern. In many parts of the world, the distance to suitable ports makes it impractical to exploit most of the coastal waters for 3D farming. Factory ships that buy the harvest from small farming operations could solve this problem. Another incentive for growing kelp is it makes a good fertilizer for land based crops, and would free up many poor countries from their dependency on foreign fertilizer suppliers. This is especially significant now that Russian and Ukrainian fertilizers are not available-both major sources of potassium and phosphorus. And it's also been shown that kelp is a superior livestock feed, reducing methane in animal flatus by nearly 100% while providing more nutrients than soy, corn or other grains, and reducing the need for antibiotics.

There are even more benefits than just those you listed. Every single molecule of calcium carbonate locks up 3 molecules of carbon dioxide. So the more shellfish the more CO2 sequestered. In addition to that these farms become important breeding and feeding grounds for all sorts of marine species, meaning that wild fish populations are being affected in a positive way.

You had me at scallops, anything to bring the price down to the point that they are affordable. I’ve seen numerous videos where they point out that the wild caught fish used for fish food is typically from less than pristine polluted waters and just pushes the toxins back up the food chain while exporting the toxins to a different part of the world. I often wondered if overfishing of invasive species such as the carp in the Mississippi River that jump into the boat would make a good alternative for fish food that might not be as toxic as the current sources that are being used. Also makes me wonder if pigs would like to eat seaweed and if so does it affect the flavor of the bacon. After all you need bacon 🥓 to wrap your scallops in. 😂

We enjoy seafood and shellfish. Bring on the 3D aqua farming. We live along the CT shore and love lobster, and fresh locally caught fish.

I agree with the idea. Could we locate these 3d farms with the offshore wind farms? Thus providing additional benefits for these areas.

I really like this idea, above and beyond

There are good reasons for why it's hard to get a permit for these kind of things. Things to consider: existing shipping, boating (recreation!), fishing, eco-system services and how you're replacing/modifying the local eco-system.

Seafood Friday was a firm tradition in my house growing up in the 1960s. Crab, prawns, cockles etc. It died off in the 1970s and a lot of fish shops closed in the UK. Not sure why. Fashions change I suppose. We started to eat pizzas and burgers, getting fatter in the process.

Saying we must produce more food while USA waste about half of what they produce mainly because of urban legends about "best before" dates (and I hear Japan bins whatever was produced before yesterday), maybe something else could be put higher on the list of priorities… For example, cooked milk bottles say to bin them past a few days after they are open, while they typically stay good to use for weeks after that. Even then, you can make cheese out of them…

i love seaweed, i even eat my nori sushi wraps just by themselves as a snack, maybe it wouldn't be the most expensive snack ever if we had a few more farms in the future!

First, I thought we were looking at an expected population drop. But the part I have the hardest time with is this. I live in Colorado. When I go to the coasts I live off sea food (I have no problem eating kelp or seaweed). Most states in the U.S. are landlocked. Sure, there’s sea food here, but in comparison to the coasts you pay more money for lower quality (frozen instead of fresh). There’s a reason you don’t find oysters, muscles, and sea bass at a Kansas BBQ. I love the idea, I’m just concerned about execution. In order to get all that fish inland you have to use high energy cooling systems in some sort of transportation that is typically petroleum based… Do we still get a benefit from this? I’m guessing you’d have to use electric boats so you’re not polluting your farming waters, electric cooling in electric… Trucks? Airplanes? Trains? to move this product… and then you have to store it (more freezers) until it’s consumed. In the U.S. the primary source of all this electricity is? Burning coal. We still have a LOT of work to do on infrastructure to make this as positive as it sounds Ike it could be… And we have to do it while politicians are being provided $500 steak dinners.

I would definitely incorporate more shellfish and seaweed into my diet. If various macroalgae species were offered as pasta, flour, and other products, it's conceivable that it could gain a lot more popularity.

I hear this but I can't stop thinking of the salmon farms in sensitive Tasmania waters in Australia. A hold has been placed on any further expansion because it's destroying these natural waters and creating dead zones below them.

There are other methods for increasing yield and decreasing waste such as better storage technics(many countries do not have big cooling storages) passive cooling with carbon,also increasing yield with giving bacteria that binds nitrogen in air or increasing ecficiency of photosynthesis thorugh gmos. Better transportation methods. We dont have any shortage in crops just one place gets lots of food other places do not thats all.

I am allergic to seafood myself but I am all for more of this to feed the world!

Your last video discussed our population collapsing. Now you are saying our population ballooning. Which is it?

The US alone disposes over 30-40% of the food it produces. Our problem isn't the lack of food, it's how it's disproportionately distributed and wasted. Restaurants throw away tons of food each week rather than donate it for various reasons. Like most of the problems in the US this comes down to greed.

NZer here. Amazing that so many people don't like shellfish! They should come to NZ and try our paua (abalone) - the best in the world, I reckon! Mince it up and make patties then fry it briefly with a bit of butter - add herbs too if you like. *Delicious!* All fish and chip shops here make paua fritters - deep-fried minced paua - awesome!

Can you use seaweed grown from these farms to feed cattle? That could potentially be used as a wedge to open to door for lawmakers in the US to get onboard, if they could be used to supplement the massive amount of corn used for feed, freeing that up for consumers since that's more in line with the current diets, and also help expose people to the culinary uses of it also? Just a random thought.

I almost never eat beef sticking mainly to pork, fish and chicken. I would definitely like to try more sea based options.

Awesome idea, growing plants in the ocean would also invite small fish and other creatures to live and hide amongst the plants and provide food for the fish as fish frequently enjoy eating vegetation. Same benefits as growing mangrove trees along coastal areas.

This topic fascinates me. I write this at the beginning. I'm mainly interested in clam farms, and kelp beds. Kelp beds can be not only a good food source, but could also be an answer to global fertilizer shortages.

Habits don’t need to change, the price does. Unlimited demand when the price of shellfish and fish are as cheap as pork and chicken is all this industry needs.

if somebody can come up with a cheap way to prepare it into something longer lasting like cured meats and keep the price well below other protein options, it would have a place in my basket - my main issue with seafood is how often I get sick from it

I love seafood, but have you seen the price? If you want to create more demand, the prices will have to come down. For instance Costco Kirkland Seaweed cost $25.78 for 10 × 0.6oz packs, or $25.78 for 0.375 pounds.

Really appreciate the efforts of ATMO device developers, but it looks like they forget the EMF exposure, which more and more people experience as making them ill. A good source for the negatives effects of EMF`s on humans and all life in general is "The Invisible Rainbow" by Arthur Firstenberg.

we also need to make a big push towards vertical land farms

way overdue, Thanks for featuring this subject

I'm at American Dairy Farmer and also in ag tech entrepreneur I can say without a doubt at least in America in throughout the world We could easily double our food production just with no in techniques like precision agriculture better management better use of fertilizer tile drainage and more irrigation but the crop prices are not high enough to justify it and when you look outside of America production per animal or per acre is abysmal even in Canada dairy farms there are less than half as productive as American farms are. Another thing that pretty much no one knows about is that the vast majority of feed that goes to animal agriculture are recycled by-products from human food consumption that used to be landfilled because they're inedible for humans but ruminate cattle can do very well on them for example we grow soybeans for soy oil for human consumption as a byproduct we have soy holes and soybean meal when you make beer you have brewer's grain and Brewer's yeast that goes for cattle when you make ethanol you have dried distillers greens that goes to cattle when you grow wheat you have wheat meds that go to cattle when you grow canola you have canola meal that goes to cattle all of this used to be thrown away. In addition much of the land is either to dry to wet to steep to Rocky to have row crop farming or greenhouses and that is perfect for grazing cattle at a very low cost they feed themselves on pasture That is the reason why so many acres are dedicated to animal agriculture because most of the land in the United States is in the west and it's too dry and low quality to grow corn or soybeans or anything else. Don't get me wrong I'm all for innovation and trying all kinds of new things and seen whatever works in a free market If we can find a more efficient low cost way to grow food for the planet that'd be great but it's not true to say that we could feed the world with our current land higher prices for food would drive up investment innovation technology and other things on farms increase production The reason why people are food insecure around the world is only because they do not have enough money not because there's lack of food or ability to get food to them.

Not true. The population is forecast to drop after reaching a peak in the next decade.

I wouldn’t mind having fish tacos more often lol.

I live on the coast of BC, and I'm surprised this hasn't taken off here more for the 3d farming. Especially with the native tribal groups taking so much control over everything you'd think this would be something they would do as they don't have to meet most government policies and controls as they currently operate outside of the systems of governance and control that most others in Canada have to play by. Who doesn't love some quality seafood! And agreed we need more of this in all places and to work in conjunction with all other segments of farming 😀

One of the issues I have is painting fish farms as positive. If you look at the salmon fish farms, they're constantly in the news as being unhealthy to eat as the fish are crammed into a small space which encourages diseases and infection in the fish not to mention stress. Also the feed for the fish is guess what? Fish meal from wild fish caught on trawlers, not very sustainable is it? Now there is a movement in Singapore to breed up insects called black fly to use as a replacement fish meal which would help somewhat however the habitat for the fish in cages is still not healthy for the fish or the people eating them still. Growing kelp, molluscs and clams though. Totally behind that! The kelp sequesters carbon from the ocean, gives fish places to hide live and breed and the molluscs filter the water as well as provide food and for people, while the kelp can supplie chemicals for the cosmetics / pharmaceutical industry.

Amazing Video bro

What are your thoughts on vertical aeroponic farming in stackable converted shipping containers like FreightFarms.

there are a few scenarios where we are not reaching 10 billion. a plateau of 9 billion, followed by a small collapse down to 8 billion also seems plausible based on the data.

Pam here…. How do you protect your farm and your crop? I would think poachers would have a field day.

This is great but we still need to reform agriculture on land. A great way is perennial grain and oil seed crops. Thia helps with water, fertilizer, and herbicide usage, decreases topsoil erosion, and makes intercropping much more economically viable to do. Check out the land institute working on this

I have seen the benefits for doing the fish side of farming in the deep seas as they are deserts of the oceans, which helps with the disease of things and the quality of the fish. I am all for being more efficient from on land farming to the ocean, and it's a good thing to evolve on all fronts.

So I don’t know if this was already brought up, but I’ll start by saying that I love the system being presented here, and what it can offer. I live in Florida and I can see something like this being very feasible to implement in certain areas of our state. However, I’d like to challenge the statement made repeatedly that there isn’t enough land to grow food. There may not be enough land to have a weed-free grass lawn and enough land to grow food. If everyone began growing SOME food in their yards, more than enough food could be grown to help meet the population’s actual dietary needs, and the offset of food needs would actually reduce the amount of mass food production needed. This has been studied a lot, and it’s not actually a space or land problem, it’s a methodology and willingness problem. It’s inconvenient to grow a garden, so we let the grocery store supply our needs. Grocery stores rely on mass production, which causes the problem discussed. We’re attacking the wrong problem. Doesn’t take anything away from the value proposition of the seafood farming venture, it’s value just doesn’t have to be based on a false or limited premise.

7:12 I love how this video clip of the fish is running backwards.

Beautiful

as far as demand: the cost of ethically & safe-raised fish is much more expensive than the wild-caught. Farm-raised has gained a bad reputation because of the very points you mentioned (thanks for being honest on that) If there were a coding or labeling of these better sea-farms, and it were priced closer to attainable; I'd adapt to safer fish/seafood.

Like so many of your listeners, you're just now catching on to this more regenerative strategy for combining food supply with support for biodiversity and climate recovery. In truth some of these ocean entrepreneurs have been refining their systems for over a decade now. So thanks for profiling it. The more people aware of the many ways we can do much better, the sooner we'll get there. How can we feed you more stories to investigate and then profile?

Life in balance. The world needs new solutions to solve the biggest problems even if not equally distributed. An increase in aqua farming would reduce the strain on terrestrial farming.

I would love to see a combination of 3 ocean farming, offshore wind and biorock to support coral growth.

Yes... I love trying new foods. And the ocean needs help balance acidic levels, which land-based farming (and landscaping) have seriously affected. It would be nice to turn that around and reduce Co2 levels as well. Great video...

Never in our history have so few hunter gatherers had to support so many who don't produce or provide anything of value

So, shellfish filters water - 150 gallons a day. Where does the "filtered material" go? Into the shellfish, of course. How healthy is that?

Is there any specific product I can try that is grown this way? We already switched majority of our meals away from beef towards chicken, sneaking some non-meat meals from time to time, might be worth to try something new in this direction, too.

Add dried kelp to salads...how easy would that be?

The viking in my neck of the woods (North of Scotland) used to collect and eat seaweed. The Church stamped this out.

we should include land use for lawns…

I find it particularly funny how these "water consumption metrics" are created and used as arguments. See, the water used in crops becomes either 1) rain through evaporation, 2) runs down in rivers, or 3) restores aquifers - all of which are cyclic, i.e. not lost. All of which can be used to irrigate more crops. Why the hell use "water consumption" for any sort of comparison then?! 🤷

Great video

I think the big hurdle is convincing people to include foods the have not gown with into the regular diet. Yes, we can go out once or twice to a restaurant and eat them but that does not solve the problem. Although I grew up in the Caribbean and my wife is from Pennsylvania our food at home never includes fish (unless I fish it and even then my wife does not like bluefin tuna). We will eat it only in restaurants. An average Spaniard consumes 92lb. of fish and shellfish per year whereas an american only consumes 19lb. The problem, we did not grow with it as part of our diet. In the Caribbean, and parts of Central an South America, the diet is rice and beans with many eating it for every single meal. Difficult to change and start eating seaweed all of a sudden.

We might not be able to enjoy eating raw oysters much longer. Just saw a video on flesh eating bacteria and it seems like its becoming more prevalent within the oyster population. It can become highly fatal within a short period of time. Scary stuff. Oysters are still great for cleaning and filtering the water though!

I live in the USA, white fish and shrimp seem good. I'd like to see scrub land used for agrivoltaics, for food, biodiversity, and/or pollinator support.

If it could be done cheaply enough; one huge market is kelp for organic fertilisers.

What I would need is a way to sample some of this stuff. IE: What is a kelp salad like? Is it similar to lettus in texture? Id imagine it some kind of slimy limp leaf which does not sound at all appetizing. On the other hand, I do love seafood, but in general, is so expensive.

The 3D ocean farming techniques sound great! But about your comments about land use - I don't know how people in the rest of the world make this decision, but I can tell you how the decision is made here on the western Canadian prairies. No farmer would graze cattle on land that is good enough to farm wheat, flax, barley, oats, canola or corn. You can make a much better profit growing grain than raising cattle. But if the soil is low-quality, all you can do is to farm animals.

It’s a very interesting space for sure. Huge potential.

One of my first concerns would be a national security one. Having a substantial dependence on farming in coastal waters opens our food supply up to being vulnerable to attack or being tainted by an enemy nation. It's also worth discussing the effects of adverse weather events on such farming. What if a hurricane wiped out x% of our food supply in a day? The idea is definitely interesting, but not without concerns.

I live in an area that was filled with shellfish. Now the industry is all but gone. The area was over fished by big company’s. The days of the small fisherman are almost gone. I do not eat farmed fish today because it tastes bad. The meat today is also very bad. Our food supply sucks now. This sounds like a better idea. 😀✌️

Maybe you wanna look into Vertical Farming and the economics of it. Maybe more interesiting probably is the Techincality in it but see for your self 👍👍

Pounds of feed per unit of meat is unfair to Ruminant livestock. There is lots of pastureland around the world that is unfit for row crop farming. Also, grasslands can be more effective than forests in the same area at capturing CO2 by building up soil carbon. Built up soils hold more fresh water, reducing the effects of both droughts and floods.

I hate when people act like we just don’t have enough food to go around. We absolutely do. The problem is waste, availability and inflated costs for the people who need it. None of these innovations matter if we don’t stop throwing away mountains of food every day! It’s sickening how much perfectly good food gets thrown out and stores/businesses destroy it rather than give it to people in need. If it can’t make them a profit then no one gets to have any. It’s horrible. I love science and innovation but I just get so irritated when people say we have a food shortage or not enough fresh water or whatever… we have people dumping clean water on millions of acres of grass for no reason other than vanity, and companies dumping tens of thousands of tons of viable food each month. If we actually wanted to feed the hungry and give fresh water to the thirsty, we absolutely could! There’s no excuse.

A couple of grand to buy a small boat. I realize I’m nitpicking but boats are expensive to buy and maintain. However, this is a very interesting video. Thanks for making this

Aquaculture isn't just the ocean you could do it in your backyard and alot more. Just need to learn filters and biofilters

I wonder if we could substitute some existing feed for cows, pigs and chickens with kelp and sea weed? This could move some farm land to the oceans sense a large amount of farm land is used to grow feed for farm animals.

We also have to many oil spills and lax industrial regulation enforcement leading to pretty much every port city and tributary where these key species thrive to be too polluted from dumping and runoff to be approved to be consumed commercially.

The demand side is easy to solve, those proteins can be fed to livestock reducing the impact on the land on so many levels. But regulation is a different story, here in the EU is more common but still hard to get around all the red tape

This sounds wonderful, I love sushi

I've greatly reduced my consumption of fish over the past decade or so because: 1. prices have skyrocketed 2. quality has deteriorated - I'm not paying $35/# for halibut that smells fishy 3. the profusion of micro-plastics in seafood 4. the environmental and nutritional negatives of farmed seafood I should mention that I do not shop at Krogers-level supermarkets. My primary food supplier is a Whole Foods competitor so, theoretically, and experientially, the quality of seafood I'm contemplating is higher than what most Americans have access to. I should also mention that, as with everything else in our economy, the concentration of economic power in the hands of fewer giant corporations exacerbates the problems I listed above. Profits above people.

i love a steak or burger but we eat fish or shellfish 3 to 4 times a week and really enjoying it great upload as usual thank you

I love seafood but I live in the Midwest

You make me wanna do fish farming. We do cattle farming and goat and sheep farming. But we still desire to have a lot more fish. I want to encourage our people to do it. One pound of feed for one pound of salmon protein? Who can beat that?

Excellent 👌

I vastly prefer kelp to kale ! Thanks, Ricky & company, for spreading optimistic news!

Biggest thing I have to adjusting my diet is price to fill value

fish farming as you say relies on feed consisting of caught wild fish so there will be eventually a limit and 3 d farming is really only for shellfish which i do not eat besides living [n uk the water companies constantly release sewerage water and we are facing a food crisis as multi national companies that produce the seeds the growing and the products we buy are providing less nutrition in vegetables and fruit and the processed foods

The main problem increasing food production environmental or not is it will have a direct effect on population... increasing it as there's more food available. Food and water is the natural control of population in every species.

I love the fact that the fear mongers never addressed the shrinking world population. We will be fine. We become more developed world and we adjust naturally to what resources are available.

Not a lot of seaweed where I'm from. Tried some, wasn't too impressed. I really like seafood though, but giving up beef? Not without a fight. Like you said, every little bit helps though.

How are oysters so expensive if there's no demand?!

we can also start having microgreen farms on a shelf in our living rooms

I did this in high school 1986-1990. it makes sense. Winchester Bay, OR. Umpqua Aquaculture. It should have taken a larger role long ago.

Could the proteins and products that are produced using ocean aquaculture not be used as feed stock for more traditions meats? That would tackle the land and water usage immediately! I know this wouldn’t tackle some of the more harmful aspects of meat production, especially beef, but it could be a start no?

i thought the plan was to drastically cull us off . WEF yay ! ugh ....

aqua farmed based products could be used as an alternate feedstock for land-based protein and agriculture.

Ricky, Did you know that cows LOVE to eat kelp? And when they eat kelp they don't fart (methane pollution cumulative amount is serious)... cheers, thanks for doing what you do. KH
