As someone who has worked in coral restoration, I find these 3D printed reefs somewhat disappointing by the pictures. It seems these structures simply get covered in microalgae that research has shown can inhibit stony coral colonization/growth. One interesting approach would be finding a way to seed these structures with coralline algae as it seems to have an opposite effect on early stony coral development.
I have to agree. I researched the endolithic algae that live inside coral skeletons (not the zooxanthellae which live inside the coral cells, but things like osteriobium), so this isn't exactly the sub-niche I studied, but I did go to coral reef confrences and heard talks and worked with people who worked on coral restoration and climate change. The pictures look like the descriptions of the worst case of climate change scenarios of coral death where the reefs get taken over by algae. I think what might eventually be neccasary is gene editing coral to survive, similar to what is being trialed on the American chesnut. But it would be so much more difficult because there are so many species.
I have a bit more confidence in three dimensional planting operations for kelp and bivalves. The latter filter the water column, and thus enable to photosynthesizers to function at greater depths. The kelp provide habitat for small organisms, usually of the invertebrate variety, which in turn provide nitrogenous detritus for the filter feeders. The farms can even be constructed off of the continental shelves, such as in deep water. Any structure which raises the coral binding substrate to 30m depth is viable for colonization. Otherwise, nature is running a large experiment in selecting corals for temperature and pH tolerance.
I just came across your channel yesterday, I am so impressed with your presentation style! Information, properly supported by detail and data, presented fast enough to be interesting but slow enough to be absorbed. What you do isn’t easy and just wanted to applaud your work 👏🏽👏🏽👏🏽
My immediate thought is that; we should try to encourage the growth of coral reefs in new environments that reefs currently do not occupy, but can be occupied as our environment changes. I do see this mindset seriously riling up conservatives, but the reality is that; climate change is inevitable, and the best we can do is to encourage ecosystems to move further away from the equator by providing them with infrastructure, or else we will loose them forever. Do I see 3D printed reefs becoming the future? Yes, but only if we can get enough support behind them to become as such.
coral are some of the most fragile organisms in the world, and the ocean is a vast complex place, currents, run offs, weather patterns and more all contribute to where coral reefs grow and thrive, making it difficult to artificially create them or choose places to even start that
@@probablynotsatan9440 I say this namely thanks to those who call themselves conservatives, but are actually just egocentrics who like to reject everything that doesn't immediately satisfy their needs. Then you have the anti-technologists who call themselves conservatives, that ain't true conservatism either, that's just paranoia and wishful thinking of an impending apocalypse. Unfortunately people like this exist, and we are now forced to acknowledge them as such...
I very much enjoyed this vlog, as soon as the alert came up and I saw the title I immediately tapped on it to watch! This was so well done, good video clips artfully connected together with excellent narration, long enough to get the idea and short enough to make it easy to watch. This is now my new favorite BC vlog. I was impressed with the successes and will now be watching for future developments in this space. My grandson did a research project on declining coral reefs specific to plastic dumping effects. I shared this with him since he became intensely concerned about coral reef decline. I’m hoping he pursues a career in marine biology. He also did a research project on whale evolution. Both presentations on these topics were really well done and far beyond his age group norm. Thank you for a vlog which I hope continues to spark his interest.
Just found this channel and I was watching the back catalog and realized you just uploaded which is pretty great timing. I really like your channel. Your ability to explain a topic is top notch.

so basically this is just the drop concrete in the ocean but in an artistic way... by the looks of the prints, they just attracted algae, and not the kind that corals like.
i think 3d printing concrete is more of a gimmick trying to use all of the tech/ocean conservation buzzwords all at the same time. seems incredibly expensive and time-consuming for what it does, not to mention the environmental impact of making concrete with no other previous use. the piers and breakwaters where I live look more lively than these, and they are just tubes and boulders. probably easier and work just as well to just blast straight boulders and stack them up, a lot more bang for the buck. don't need to be bolted down and use expensive large stainless steel fastening. get enough of them together and you got all the crevises you want. for those who don't know a "breakwater" is where they just build a massive T shape out into the sea to stop waves reduce sand erosion and create the right wave conditions for surfing(same name for the structures at the entrances of harbors). but they have become sanctuaries for local stingrays and fish. so like shuffle your feet if you are swimming near one so you don't accidentally step on one.
I could also see this technology being used to create more eco-friendly wave breaks or assist in things like the restoration of oyster reefs in colder waters.
Belinda, your videos are amazing! You've got a talent for explaining complex issues in a way that's easy to understand. And you do it without wasting any time. I find myself skipping a lot, when watching creators, who say a whole lot if nothing. So I enjoy how straight to the point you are. Please keep making videos! ✌🏽😁

Have a look at the perforated concrete pyramid shapes that are being used off the SW coast of Western Australia. They are meant to encourage Abalone but they get colonised by other marine life. Also around Sydney small terracotta pots have been attached to the many human made sea walls which replaced the natural shoreline of Sydney's multiple harbours. There are many steps we can take small and large to assist nature. The best would be to save, restore and replant seagrasses and mangroves and to work with nature not treat it as the enemy or a way to make a fast buck.
im so glad i found you today. i can't believe content like this is free LMAO like im actually invested in yt for once.. whatever you're doing keep doing it.
Wasn't aware that coral reefs were under any particular threat. We heard such nonsense back in the 80s and 90s and the fear mongering about how it would take millions of years for reefs to recover from who knows what. The navy sank a few decommissioned ships off shore and a decade later, reefs were doing better than ever. The one thing that has come clear in all of it is that credentials aren't worth much.
I've just recently found you and I'm obsessed with your content. It's so informative and the impartial nature is so refreshing in a world where we're constantly bombarded with fake and sensationalist information. Keep up the good work 👏
3D printed structures look good to attract fish and others, including divers, which should be good for local economy. I cannot see how they will save reefs. It is like a drop in the ocean.
Your channel has been a really wonderful discovery. I have no background in architecture, but you present your topics in a highly engaging, intelligent manner that rises above a lot of the more amateur styles on UA-cam 😊
What gets my brain turning with this is that I recently learned about another technology for building large concrete structures underwater. It had a really goofy name but it was brilliant. They anchor a large steel cable and run electricity through it. This anodizes the cable with minerals from the water. Next thing you know you have a solid stone pillar that's completely natural. If instead we dropped steel netting I wonder if we could build large stone structures super easily.
They'll definitely have to find a way to make it cheap and sink it even cheaper. It's got to be extraordinarily expensive to go down and bolt those. Awesome start though! I never knew about this.
Great video. You well summarized the issues, and even touched on something big government groups don't get. . . Therre is no one solution that will work everywhere. I was also proud to see one of my pictures in there
Hi Belinda, I was wondering if you have any knowledge on glazing alternatives to glass, that don't have as large a carbon footprint and environmental impact as silicon based glass. I've been wondering this ever since researching on the huge amounts of sand excavated to produce glass and concrete. You seemed like you'd probably know.
I have only today discovered your channel and I have been binge watching all of your videos; they are so informative. Thank you for sharing your knowledge.
Thank you for your impartial takes on all of these issues. Its all too rare that I can simply adsorb information without staying on guard of a personal agenda or bias from the orator. Keep up the great work!
I haven't even watched the video, I just clicked on it from seeing the thumbnail and title. I came here just to make the comment that if we're at the point that we (as a species) have to reproduce something that would otherwise already be a naturally occurring thing, then we've got a problem... Edit: After watching the video, I can see that this is exactly the thing that the video is trynna address and providing this as a solution to humanities already irreversible damage. Very good video and explorative!
I think if you want those things to host coral, as opposed to moss, you've probably got to seed and culture coral on them before emplacement. I'm seeing moss (algae) covering the type of stones where coral used to get started and then keep coral off of it.
This could be a useful approach to accelerate reef development in areas that suit human activities (e.g. to enrich a fishery) - but I think it's hubris to assume we can do a better job of establishing reefs, than the organisms that have been building them for hundreds of millions of years. During the seasonal spawning events, corals release billions of propagules _en masse,_ and ocean currents can carry them many hundreds of kilometres before they settle on a substrate. Our efforts at establishing new reefs look pretty puny by comparison.
3D printing is clearly not going to save our marine life, just like it's not going to solve human homelessness, but we have to keep fighting climate change and its effects. 3D printing might be able to help in a small way and I support any effort to protect life in our oceans. I hope it's not too late.
The simple answer is no because the reason why coral reefs are dying isn't because of lack of surface area but adverse changing environmental conditions. If anything, these new forms will make things worse because they will reduce the flow of the ocean currents which the coral needs to survive as those corals need the current to bring in food, oxygen and carry out deoxygenated water, waste and fertilized eggs. And the creatures which these objects most benefit are algae which reduce the ability of the corals to latch onto the structures and survive anyways. The whole 3d printing nonsense is a gimmick. A money hole that isn't really as useful as claimed and far more costly than people think compared to alternative methods. Frankly trying to throw out 3d printing as the solution to every problem even if that problem cannot be resolved by 3d printing is turning 3d printing into the new hammer where every problem looks like a nail if 3d printer is the new hammer buzzword.
A precast modular concrete reefs are faster and cheaper to build, stop looking at 3D printing, not everyone can afford it compare to conventional concrete builds. Let's say you 3D printed 32 coral reefs, with that same amount of cost and time, you could have precast more than a 100 coral reefs that have the same result.
these shapes seem to have a lot of internal pieces that are very complicated, unless you’re casting multiple parts and connecting them I dont know how you easily mold this without a fresh mold every time
@@jurrasicore8682 you will be amazed by the varieties of shapes and forms of cast concrete. Moreover, those shapes are obviously overdesigned, just like she said, rebuilding homes for aquatic creatures is just like solving homeless issues with "low cost" buildings if the main cause of the destruction of coral reefs isn't solve yet.
Some misinformation in this video. Climate change has zero effect on coral reefs. First off ocean waters don't get "acidic", as far as PH goes most if not all organisms adapt to the changes, sea water is also great at neutralizing Co2's. Warm weather does not bleach corals,, reactive nitrogen from sources like improperly treated sewage, and fertilizers do. Coral reefs were dying off long before they were impacted by rising water temperatures. Elevated nitrogen levels cause phosphorus starvation in corals, reducing their temperature threshold for bleaching. For instance in the
I do not remember how I found your channel, but I discovered it yesterday. I have never seen so much insightful content involving building science. You push through the buzz words and click bait garbage everyone else on this platform seems to be peddling. You attack the issues with a sense of optimism but all through the lens of practicality. It's almost impossible to find people willing to discuss drawbacks on what seems to be "the next big thing" that will "revolutionize" the industry. I have been binging your content. That's a sub from me!!
I enjoyed watching this talk. It is great that people are experimenting to help the oceans. I watched a documentary on You Tube about two weeks ago. It was stated by the presenter (scientist/biologist) that the Great Barrier Reef has in fact repaired it self very recently. Unfortunately I don't have the link and I don't remember his name:)
It's not. They are trying to force every problem into a 3d printer solution even if that option is vastly more expensive than alternative options and vastly underperforms other options.
@@williambinn1028 - So anybody that disagrees with you, marine scientists, government bodies - the overwhelming majority of experts in all related fields are all handicapped...and doom sayers. Or it may be that the polyps don't like hot water.
Underrated channel, I would be curious to know what you think of something called "Earthships" by a man in New Mexico I believe. He's got a very interesting life story overall and I'd be curious to know your thought about the whole project.
They're part of the solution to coral restoration at certain sites. "These solutions give us a glimmer of hope." - it's not a panacea, but it's something
The success of coral reefs comes down to a few specific species of bacteria. They have to figure out what water conditions are favorable to fix this problem.
The trains mentioned at the beginning were used for quite a novel reason, they're from the first generation of Inox Steel/Stainless Steel trains, so they will last for Quite a While, to say the least
First love your channel, it´s a gem! To the good question in the 3d printed reefs, why don´t make holes to settle in coral frags in later when the artificial reef has matured a little bit
Why do you need to 3d print coral? Just seed the reef and let nature do its thing. We've got to stop trying to engineer our way out of every problem. It was our attempts at engineering our world to suit us that caused the problems in the first place.
The coral reefs cycle growth themselves, there is no need to "save" it. The great barrier reef has record breaking growth and is the biggest it's ever been today.
Compensatory growth after a massive bleaching event is not cause for celebration when metabolic exhaustion and stress from rapid growth leave those same corals more vulnerable to increasingly common extreme temperature events.
@@jinmushui1souli remember watching the saturday show on tv in queensland showing video of divers, on the baron blenched white coral and saying it was because of a foriegn invader, the crown of thorns starfish. both claims were wrong. The gbr has had bleaching events, massive and localized events for thousands of years that we know of. these are linked to el nino/nina events and localized events involving tidal and brief heat events (which also have occurred for millennia). coral, in the broad, is formed by individual creatures.once they die that's it. new creatures come and form the next coral structure. there is no "exhaustion or stress'. they are not on shift work or pulling a wage. they don';t have a union? these types of terms try and create a human relationship/cause to unrelated events. also what is your metric for "increasingly common" extreme temperature events? the reef is about 8k years old as it developed since the last ice age. we have only had the capability for 40-50 years to monitor (not saying we even did) the reef via satellite since the reef is mostly between 10-100 kms off shore.
@@dixonmcklacker6210 - If global warming continues the coral will migrate off the equator into cooler water. It sounds to me you are not a great believer in Anthropogenic Global Warming
It may be possible to preserve some coral species with a method like this, even in a more acidic ocean, whilst the calcium carbonate skeletons may dissolve away as the ocean acidifies the polyps themselves fundamentally only need a solid structure to attach to to survive, if we can preserve the polyps in the surfaces of artificial structures like this we may be able to help the polyps themselves and thereby the coral species survive until the ocean becomes less acidic again one day

these shapes seem to have a lot of internal pieces that are very complicated, unless you’re casting multiple parts and connecting them I dont know how you easily mold this without a fresh mold every time
@@jurrasicore8682 you will be amazed by the varieties of shapes and forms of cast concrete. Moreover, those shapes are obviously overdesigned, just like she said, rebuilding homes for aquatic creatures is just like solving homeless issues with "low cost" buildings if the main cause of the destruction of coral reefs isn't solve yet.
Scaling this up with microstructures is the main challenge. Maybe mold casting cubic frames with microstructures is a good approach
Some misinformation in this video. Climate change has zero effect on coral reefs. First off ocean waters don't get "acidic", as far as PH goes most if not all organisms adapt to the changes, sea water is also great at neutralizing Co2's. Warm weather does not bleach corals,, reactive nitrogen from sources like improperly treated sewage, and fertilizers do. Coral reefs were dying off long before they were impacted by rising water temperatures. Elevated nitrogen levels cause phosphorus starvation in corals, reducing their temperature threshold for bleaching. For instance in the
Thanks for the prep you put into these videos. You're intelect is so interesting, I'm hooked.
Your videos make me swell with nerdy pride! 🤩
Came for the roast of container homes. Stayed for the insight on such varied topics. 10/10 would recommend.
I do not remember how I found your channel, but I discovered it yesterday. I have never seen so much insightful content involving building science. You push through the buzz words and click bait garbage everyone else on this platform seems to be peddling. You attack the issues with a sense of optimism but all through the lens of practicality. It's almost impossible to find people willing to discuss drawbacks on what seems to be "the next big thing" that will "revolutionize" the industry. I have been binging your content. That's a sub from me!!
Very good coverage of what’s going on.
I think this a good example of building on ideas and learning from the past.
People will do everything just to treat the symptoms but not treat the cause of this mess
Fantastic Video, so glad UA-cam suggested your channel. Love your high quality content. Insta sub.
What are the advantages and disadvantages of mud houses?
very informative video, i enjoyed watching!
I enjoyed watching this talk. It is great that people are experimenting to help the oceans. I watched a documentary on You Tube about two weeks ago. It was stated by the presenter (scientist/biologist) that the Great Barrier Reef has in fact repaired it self very recently. Unfortunately I don't have the link and I don't remember his name:)
6:50 photo on the left: source? where can i buy this? Im a reef keeper and i'd like to experiment with it.
Wow! So interesting. I never thought of 3D printing being so versatile.
It's not. They are trying to force every problem into a 3d printer solution even if that option is vastly more expensive than alternative options and vastly underperforms other options.
@@GeorgeMonet - really ? You think its some sort of conspiracy ? Surely these research programs will rise or fall on their own merits.
It's unfortunate that concrete is included for these reefs because of the huge carbon cost associated with it's production.
Pretty cool, i hope they work in the long run
Could you do a video on the pros and cons of construction with SIP panels? Thank you, great content.
Interesting topic. Well presented. Thank you.
Polution, yes. But youre wrong about the rising temp and death of the reef in Australia, its healthier now than it ever has been.
Really ? you got any links to this information ?

I think the Coral Reefs have a future IF they first prototype before throwing them out into the ocean; we don't need another tire problem after all.
They just reported the great barrier reef is at record high levels. The reefs recovery has come along way.
Great content!!
Underrated channel, I would be curious to know what you think of something called "Earthships" by a man in New Mexico I believe. He's got a very interesting life story overall and I'd be curious to know your thought about the whole project.
Short answer no. Long answer noooooooo
They're part of the solution to coral restoration at certain sites. "These solutions give us a glimmer of hope." - it's not a panacea, but it's something
Mam , how to add coordinate values (X,Y,Z) for structural column in revit??
The success of coral reefs comes down to a few specific species of bacteria. They have to figure out what water conditions are favorable to fix this problem.
The trains mentioned at the beginning were used for quite a novel reason, they're from the first generation of Inox Steel/Stainless Steel trains, so they will last for Quite a While, to say the least
These are really beautiful structures
Great attempt, but it's like trying to revive your dying plant with a bit of water, while you continue to urinate on it every day.
First love your channel, it´s a gem! To the good question in the 3d printed reefs, why don´t make holes to settle in coral frags in later when the artificial reef has matured a little bit
The Great barrier Reef is recovering right now. New polyps have been born and now the Reed is healthier than was a decade ago.
Why do you need to 3d print coral? Just seed the reef and let nature do its thing. We've got to stop trying to engineer our way out of every problem. It was our attempts at engineering our world to suit us that caused the problems in the first place.
1:22 finally, a practical use for shipping container homes.
can you do a video on sea crete, they send current through a metal structure and it causes all the calcium in the sea water to cover it
The coral reefs cycle growth themselves, there is no need to "save" it. The great barrier reef has record breaking growth and is the biggest it's ever been today.
Compensatory growth after a massive bleaching event is not cause for celebration when metabolic exhaustion and stress from rapid growth leave those same corals more vulnerable to increasingly common extreme temperature events.
@@jinmushui1souli remember watching the saturday show on tv in queensland showing video of divers, on the baron blenched white coral and saying it was because of a foriegn invader, the crown of thorns starfish. both claims were wrong. The gbr has had bleaching events, massive and localized events for thousands of years that we know of. these are linked to el nino/nina events and localized events involving tidal and brief heat events (which also have occurred for millennia). coral, in the broad, is formed by individual creatures.once they die that's it. new creatures come and form the next coral structure. there is no "exhaustion or stress'. they are not on shift work or pulling a wage. they don';t have a union? these types of terms try and create a human relationship/cause to unrelated events. also what is your metric for "increasingly common" extreme temperature events? the reef is about 8k years old as it developed since the last ice age. we have only had the capability for 40-50 years to monitor (not saying we even did) the reef via satellite since the reef is mostly between 10-100 kms off shore.
@@dixonmcklacker6210 - If global warming continues the coral will migrate off the equator into cooler water. It sounds to me you are not a great believer in Anthropogenic Global Warming
@@dixonmcklacker6210 Finally, someone speaking sense who isn't brainwashed
I found this video fascinating !
Artist was making underwater sculpture gardens. Could these be self funded coral farms?
It may be possible to preserve some coral species with a method like this, even in a more acidic ocean, whilst the calcium carbonate skeletons may dissolve away as the ocean acidifies the polyps themselves fundamentally only need a solid structure to attach to to survive, if we can preserve the polyps in the surfaces of artificial structures like this we may be able to help the polyps themselves and thereby the coral species survive until the ocean becomes less acidic again one day
Excellent episode
UA-cam just showed me a complete scam ad.. Didn't know they're opening up ads to scammers now. It claimed a phone charger block, will speed up your phones performance... Thats so ridiculous.
First they tell me plastic is bad in the ocean, now they want us to throw a ton on there
