\nThe Great Barrier Reef is the largest living structure in the world, spanning 1,400 miles of Australian coast and roughly the equivalent area of Japan. But how did it come to be that way?
\nCoral are an ancient animal, they've played a role in shaping coastal seabeds for about 500 million years (Zuravlev, 2001; Lee et al., 2015) -- they're older than trees and they're older than sharks!
\nCoral are really a collection of a bunch of individual coral polyps that each help build up the reef.
\nSHANE: Basically, coral will suck water into their stomachs, push out all the water and the things in that water that they don't need… except for… calcium and carbonate…and when the ions are squeezed together under their tissue, and all the water squeezed out, it creates a really thin layer of rock underneath it
\nOver time, that rock base builds into the reef structures that we see today.
\nGoing back in time, just before we see apes evolve, the continent that Australia is on finally shifts northward enough to have a tropical climate that can support coral reefs. Thus, the Great Barrier Reef begins about 20 million years ago (Hamylton et al. 2022, pp. 104-107).
\nBut, it wasn't until about 600,000 years ago that we start to see the reef structures that form the Great Barrier Reef today.
\nYou see, it's not actually all one reef. Today, the Great Barrier reef is a system made up of over 2,900 individual reefs (Great Barrier Reef Marine Park Authority, 2006). It's not just one huge neighborhood, it's more like a city made up of a bunch of different neighborhoods.
\nAs sea levels changed during the Ice Age, the Great Barrier Reef tried to keep up and follow the coastline as it moved, but it wasn't always able to and so the reef died out (Hamylton et al., 2022, pp. 124-130).
\nThe reef we see today started growing around 8,500-9,000 years ago. It was able to build on top of the old structures made by the ancient reefs that were there thousands of years earlier (Hamylton et al., 2022, pp. 124-130; Great Barrier Reef Marine Park Authority, 2006).
\nTogether, they build a layered cake of chalk that's thousands of years old and still being built today!

\nI have some great news! IVF for coral works!
\nCoral spawning season occurs in late summer, around August, and usually happens a few days after the full moon, but since 2016 coral have had some help from scientists during spawning season!
\nIVF stands for "in vitro fertilization," and for coral that means taking coral spawn and either fertilizing them in a lab or putting them in pools like these to promote reproduction. Once the offspring are released and attached to the reef, these younger IVF-bred coral are far more resilient to climate change!
\nThere was a huge marine heat wave in the Caribbean in 2023, and the bad news is that about three-quarters of the native colonies of coral were bleached or paled. You see, coral is a symbiotic organism and it gets most of its nutrients (and its color) from algae that live within it, called "zooxanthellae." When a coral is stressed -- say by extreme temperatures -- it might get rid of that algae. And that's what bleaching and paling is.
\nBut 90% of these younger, IVF-bred coral were totally fine! We don't know why yet, but one of the theories is that these younger coral are more exploratory, and they'll try different types of algae, some of which are more heat resistant.
\nNot only that, but we know that these IVF coral can reproduce in the wild -- because they did for the first time in 2021 in the Great Barrier Reef!
\nIVF is just one of several ways that scientists have found to help protect and repopulate our threatened coral populations, and it's great to hear that it's working just swimmingly!

\nI'm gonna get the bad news out of the way first so the rest of this video can be fun. I'll be quick, I swear, put 30 seconds on the clock!
\nCoral are bleaching and dying at an alarming rate due to pollution, warming oceans, and ocean acidification. We've lost about 50% of coral by area since the 1950s, and species extinctions are happening far faster than the natural rate.
\nWhile it's a complicated subject, let me be clear: there is no doubt that human activity is largely to blame for these trends.
\nBut that's not news, and that's not what I want to talk about today. I'm going to talk with some of the people who are actually doing something about it, and I want to share some of the cool science that's going into their work to make it happen. So let's get started.
Coral are neat little guys because they're not really 1 thing? They look like some weird cross between an animal, a rock, and a plant. And that's 'cause that's exactly what they are!
\nCoral is made of 3 parts: an animal, a rock, and a plant. The coral animal is a cnidarian, meaning it's related to sea anemones and jellyfish. The animal part is just the jelly-y bit on the outside.
\nThe coral animal builds up mineral and rock to form a skeleton for itself, and that ultimately forms the solid foundation of the entire reef.
\nFor the last part, tiny photosynthetic algae called "zooxanthellae" live inside the coral animal.
\nThey're only… kind of? plants? But what's important is that they photosynthesize, and that ends up providing energy to the coral animal. The zooxanthellae are what give coral their color, and they could give you 32 points in Scrabble even without a double word square wink.
\nCoral can reproduce in a bunch of different ways, which gives restoration scientists a lot to work with. But most importantly they can reproduce asexually or they can reproduce… sexually. Follow me ;)
\nAsexual reproduction is awesome! It means that coral can reproduce without sex! There are several ways they can do this, but the most useful to restoration scientists is fragmentation. I talked with Shane Wever from Reef Renewal USA about what that means.
\nSHANE: So fragmentation is an asexual reproduction methodology used by corals. You can think of it a lot like propagating a plant. When you cut off a small chunk of the plant, and you create that propable that you'll stick into potting mix. We do the same thing with corals except we cut off a little piece and we can stick it back on the reef.
\nBEN: Shane is the restoration program director for the upper keys. Reef Renewal has been building out coral nurseries and replanting coral for about 5 years now.
\nSHANE: Reef Renewal USA was started in 2019. Its focus is to make resilient corals for the future. Our goal is to outplant 100,000 corals a year.
\nBEN: But what does that work look like?
\nWell a lot of it is diving! They'll carefully break or saw off pieces of coral and then bring those to the nurseries. The nurseries are where the fragmented coral are grown, and Reef Renewal USA's workers or community volunteers will keep a close eye on them.
\nShane told me about 2 different types of nurseries that they use
\nSHANE: When we propagate our corals, we grow them on a couple different structures. We have PVC trees, and we have VERNs, which are Vertical Rope Nurseries.
\nBEN: The PVC trees are exactly what they sound like -- they're tree-shaped structures made of PVC piping. There are two types of these.
\nSHANE: One is going to be hanging corals from these branches with fishing line. The other is going to have trays that are modular units that we can actually stick corals on where we can organize corals on these little frag plugs.
\nBEN: But that's a more traditional approach. The Vertical Rope Nurseries, or VERNs are being used more commonly these days
\nSHANE: Vertical Rope Nurseries have become our standard for growing branching corals. Basically, you put some buoys on the top of a rope, and the bottom of the rope is going to be secured to the sea floor. That rope is kinda spun up, and when you unspin that rope, you can stick a fragment of coral inside of it.
\nBEN: What's really cool about these VERNs is that they're able to move with the tides and waves! That's also why they're often preferred over the trees: The PVC trees might break during a storm or rough waters, but the VERNs will move with the water and help buffer out that stress
\nSHANE: When hurricanes or storms come through, it doesn't smash them around, and it makes these VERNs a lot more resilient. And it also gives them a thinner profile, so they take up less space in our nursery, which means- which means we can have more structures.
\nBEN: Coral restoration isn't easy work -- there are lots of early mornings, long days of diving, and you're kind of fighting against the environment
\nSHANE: You have to rely on good weather, you have to rely on the ocean having good conditions -- not just for the divers, but for the corals.
\nBEN: On top of the weather, there's also diseases, parasites, and…
\nSHANE: Unfortunately in 2023, we had one of the worst bleaching events that the Caribbean has ever seen
\nBEN: Wait, what's a bleaching event?
\nRemember the zooxanthellae? The algae that give coral its color? When coral get stressed, they'll get rid of their zooxanthellae. And that's. Bad.
\nSHANE: So without it, they would look white. And so when you see coral bleaching, that is a coral that has, from some stress event, lost all of its symbiotic algae, and it's starving itself.
\nBEN: Yeah, not good. Coral bleaching won't immediately kill the coral, but it will kill them pretty quickly if the stress continues.
\nThe 2023 marine heat wave in the Caribbean was really bad -- some coastal temperature sensors reported water temperatures reaching 100 degrees Fahrenheit.
\nSHANE: I think it was the worst that we've ever seen. And so years of restoration work was wiped out. Hundreds of thousands of coral that were stored in nurseries were gone.
\nBEN: It can be a tough job, with climate change seemingly working against you. But these guys don't give up.
\nSHANE: But, that didn't stop us. We, ya know, we pivoted, we made adjustments, we made changes. We were able to salvage some of those corals. In doing this, we have also been able to revolutionize some of our techniques to make our propagation more successful
\nWe have a facility that used to create live rock and they're now creating a gene bank of all of the corals that we can salvage out on the reef, but also turning it into a propagation pipeline where they're generating hundreds and thousands of corals to then send down here to practitioners so we can really boost the effort and the capacity that we have to restore the reef at scale.
\nBEN: Part of the problem with fragmentation is that the offspring don't have any genetic diversity. The new coral are clones of the old ones. You can expect them to perform about as well as the parent coral! The problem is, with the changing climate, the parent coral might not be doing so well.
\nHANNAH: The problem with this asexual reproduction method is, all of the new individuals that are created are genetically identical.
\nBEN: That's Hannah Ditzler. She's on the research team for SECORE international.
\nHANNAH: Corals are quite fragile, so if a disease comes through, a stress event, etc, all of those corals can get wiped out because they're genetically the exact same.
\nBEN: SECORE is an organization that's taking a different approach. SECORE literally stands for "sexual coral reproduction," and that's exactly what they're doing.
\nHANNAH: This is a different approach because we're creating a lot more genetic diversity, um, and it has the potential to basically breed in qualities that we want the corals to have.
\nBEN: This method allows for genetic diversity, and that might give these young coral a better chance at surviving different stressful events.
\nAs a matter of fact, SECORE published a study just last year showing that their IVF-bred coral were far more resilient in the 2023 Caribbean marine heat wave!
\nBEN: I asked Hannah to tell me the story of coming to these findings
\nHANNAH: I think a lot of us during the 2023 mass bleaching event were really, really impacted by the state of the reefs. I know people were literally crying underwater watching these, ya know, giant [Acropora] palmata that have been around for tens to hundreds of years bleaching and reproducing. So we saw corals that were literally completely bleached actually reproducing and then pretty much dying. So, it was really, like, an emotional experience for a lot of us. And it was really hard to see, it was really hard to see. But, at the same time, we were seeing that basically corals right next to juvenile outplants that we had created were completely bleached and dying and recruits that we had outplanted were actually fine. We kind of started seeing this data in Mexico and Curacao, which are our 2 other main office locations, and so we decided to investigate with our partners that are all over the Caribbean. We had people go out and collect as much data as they could on the different recruits that were out there and try and get good comparisons of adult colonies, parent colonies, or other close corals that were in the area. We essentially found that the recruits were bleaching at a much lower rate than the adult colonies were, even, ya know, within meters of each other. So, colonies that were right next to each other that were juveniles were totally fine and these adult colonies were bleached and hit really hard by the warm waters.
\nBEN: So how does this technique differ from using fragmentation?
\nWell, fragmentation is pretty simple -- you break off a piece, plant it, and wait for it to grow. Assisted sexual reproduction is a lot more complex, but let's break it down into 4 main phases: Collection, Larvae, Attachment, and Planting -- or CLAP!
\napplause
\nFANCY BEN: Oh, thank you so much! Thank you!
\nBEN: In the collection phase, scientists are monitoring the reefs and can predict roughly when the coral will reproduce.
\nHANNAH: They basically release their gametes in a synchronous event based on full moon cycles and sunset times. So, all corals of one species will essentially time their reproduction so that it happens at the same time. We are basically able to predict when certain species of coral are going to reproduce within an hour or two on a specific set of days.
\nBEN: These scientists will go out on the water in the middle of the night to monitor for the synchronous spawning event, and when it finally happens, they'll be out there with nets and other equipment to collect the gametes
\nHANNAH: We will bring collectors and basically place them over the coral. They look like a little tent made out of mesh, and they have weights on the bottom so they sit on top of the coral, and then they have a little floating tube that sits on the top of them.
\nBEN: Once that's collected, we move onto the Larvae phase. The gametes are mixed together to allow them to fertilize, and then when the eggs hatch, the larvae are put back out in the ocean in what are called CRIBs
\nHANNAH: SECORE uses CRIBs, which are coral-rearing in-situ basins. They are essentially these big, blue, floating pools that go in the ocean, and they allow for half a million larvae to be settled at a time.
\nBEN: After that, it's more waiting and monitoring development. Part of what they're looking at is the fertilization rate.
\nHANNAH: Sometimes we can actually get fertilization rates of near 100%, which is great, and that's not something that would necessarily happen in the wild.
\nBEN: When the larvae get old enough, they turn into planulae. During this phase of their development, they start looking for a place to settle, bringing us to the Attachment phase.
\nHANNAH: They basically start swimming around in circles on the surface of the water, and then right when they're ready to settle, they will swim down to the bottom of whatever container they're in.
\nBEN: The planulae are looking for a hard surface to attach to. At this point, they're still in captivity, but they'll settle on a substrate and start growing into the animal/rock/plant combo we all know and love!
\nAfter more waiting and monitoring, these new recruits will be ready to outplant
\nHANNAH: Once they settle, we're able to check their development and their growth, and then either outplant them or keep them in captivity to rear until we decide to outplant them.
\nBEN: This technique does come with its own unique challenges and drawbacks
\nHANNAH: I mean, asexual propagation is much simpler. You're taking a coral, you're cutting it up, and you have 2 corals. And it produces a lot more biomass a lot more quickly than sexual reproduction ever will. So that's super important, ya know. Fish won't hang out on a reef that doesn't have any biomass.
\nHANNAH: Sexual reproduction, it's definitely not an easy way of doing things, um, but it is kind of the only option especially when we're, you know, losing genetic diversity on reefs at such an alarming rate. It's a much more lengthy process, it's a lot more technical, and a lot more difficult and requires huge amounts of man-hours and a lot of technical knowledge on how to do it. And so, while we are able to produce a lot of corals, they take a long time to grow to reproductive capacity and to have any real impact on a reef.
\nBEN: So in summary: Asexual reproduction is simple and well-proven. It can be done at-scale and it restores biomass quickly, BUT all the new coral are clones. Sexual reproduction is complicated and it takes a long time, but it can also be done at-scale and it's able to restore genetic diversity.
\nSo what does the future look like? Well, there is a lot to be concerned about, but there is a lot of hope.
\nWe're still losing coral, but the rate has slowed down a lot in the last 20 years.
\nWe also got some really good news in 2021, when we saw these IVF-bred coral reproduce on for the first time on their own in the wild.
\nHANNAH: Curacao was actually able to see their- one of their earliest rounds of recruits reproduce. This basically shows that we're able to close the loop of sexual reproduction with the work that we're doing. That's hugely important, that's really the goal of all of this work is to restore reefs to a point where they are able to do it themselves, and we don't really need to be involved.
\nBEN: With all the good and the bad, how do our experts feel about the fate of coral?
\nSHANE: I think they have seen so much devastation in the last 50 years, um, but we don't know much devastation they've faced in the 100 or 200 years before that.
\nHANNAH: Yeah, that's, ya know, that's a tough question. Um. I think that it kind of depends on what's going on. We are doing the work that we're doing now because the reefs are so degraded that in some places, there are not enough parent colonies to successfully reproduce.
\nSHANE: The coral reefs of tomorrow aren't going to look like the coral reefs of today or the coral reefs of, ya know, my grandparents. As a community, locally, we need to look ourselves in the face and figure out how we can make our marine environments healthier. And as an entire country -- and even farther as an entire world -- we need to really look in the mirror and say "do we really want to be doing this to the food that we're eating? To the places that we're swimming? To, ya know, the- to the place that regulates our climate, honestly?"
\nHANNAH: But, I do have hope that we can do it, otherwise I wouldn't be doing this. And there are reefs out there still that are incredibly beautiful and healthy.
SHANE: I can't be helpless, right? I have to be hopeful because hope is all I got right now, and as long as there's still one coral out on the reef, I'm gonna keep on working as hard as I can to keep that coral healthy.
\nHANNAH: So I think there is a lot of hope, um, out there as well, and we're really learning a lot. So I have hope that, ya know, we can figure this out. It's not gonna be easy, and, you know, we need to continue to get funding, we need to continue having people dedicated to doing this, and we need to address the concerns of climate change. Ultimately, coral reefs are not going to continue to exist if we don't get a handle on climate change and… make sure that our oceans don't warm to 100 degrees like they did here in the Florida keys last- or 2 years ago.
\nSHANE: Community engagement is gonna be the most important thing. We have partnerships throughout the community, working with dive shops, recreational divers, and volunteers in so many capacities to really get the community as a whole to be a steward for the ocean. But more awareness and more engagement, and teaching the people that you love and the people around you about coral reefs is- is free, and is one of the most impactful things. Letting them fall in love with coral reefs is gonna be my best bet to making everybody else care about coral reefs the same way I do.
\nSHANE: You know, I can't help but have hope for coral reefs.
\nHANNAH: It's, you know. You gotta keep going. You gotta keep going…
\nBEN: So the future depends on us, it depends on you. We need to be funding science -- if governments won't do it, we need to be helping with volunteering and fundraising. Shane talked about community-building, getting your local community to care about the local environment and to care for it.
\nBut also… governments do need to be doing it -- contact your representatives and make sure they support funding science foundations. I'm gonna leave a link to 5calls.org in the description below. They make it really easy to contact your representative about about specific issues.
\nThere's so much work being done, and like Shane and Hannah said, we really need to keep it going. I'm really excited to see what we can do together moving forward!
\nIf you'd like to learn more or get involved, there are plenty of organizations in the US to donate to or volunteer with. YOU can be the one to go out on the reefs, dive, and plant new coral, that's so freaking cool! I'll link a few of these organizations in the description below.

The overwhelming feeling I got from reading that book was dread at the building realization that microplastics really are everywhere. They're on the top of Mount Everest, the bottom of the Mariana Trench; they're in the air and the water; they're in our lungs and in our blood.
\nFor A salad full of glitter, I wanted to take a more cinematic approach. This was partly because I wanted to stretch my creative chops, but also because I wanted to tell a story of sorts: I wanted to tell a simple story about a person going about their regular day-in-the-life, but everywhere he turns, he encounters plastics and microplastics. I want the viewer to have the same journey I did during my research, realizing that we are absolutely surrounded and there is no escape.
\nThe video has some useful tips for how to reduce your own exposure, but the truth is that you cutting out plastic straws and bringing your canvas bags to the store isn't solving the problem. This is a global issue, and we need to be taking it seriously and pressuring policymakers around the world to do better.

\nIt's been said that every piece of plastic that's ever been produced still exists. In your home. In an office. On the side of a highway. Neighborhood streets. In rivers that lead to the ocean.
\nAnd while it's basically impossible to really verify that claim, scientists estimate that of the 8.3 billion metric tons of plastic that we've produced, 6.3 billion metric tons have ended up as waste. About 9% of that has been recycled, but the rest has been incinerated or just discarded (Geyer et al., 2017)
\nWe've known that this is a problem for a while now, but we're only just starting to realize how much of a problem it is. See, because you and I, we're thinking of straws in turtles' noses and seagulls choking on plastic rings, but there's a more alarming side to the plastic pollution epidemic, and it's reached every corner of the earth.
\nFrom your home to remote forests, from the top of mount Everest to the bottom of the Mariana trench, we're finding them everywhere: microplastics
\nTo know what we're up against, we first have to define them. So what are microplastics?
\nMicroplastics are any piece of plastic that are between 5 millimeters and 1 micrometer in size. So we're talking on the scale of anything from a pencil eraser down to smaller than a human hair.
\nTechnically, any piece of plastic smaller than 1 micrometer is a nanoplastic, but for the sake of this video, we'll just consider anything less than 5 millimeters a microplastic.
\nAnd that's kind of a whole thing -- because we've known about microplastics for a while now, but a lot of research and studies are still pretty new, so a lot of standards and definitions haven't been defined yet.
\nThere is, however, a broad distinction between "primary" and "secondary" microplastics.
\nPrimary microplastics are made to be microplastics. Most commonly, this is used in industrial air blasting. A bunch of tiny microbeads are added to the air to increase scrubbing power. But until the mid 2010s, microplastics were added to your toothpaste as well for the same reason -- mixing in a bunch of microbeads into toothpaste makes it more abrasive and helps scrub your teeth clean.
\nAs a matter of fact, 9 out of 10 cosmetic products have microplastics in them -- shaving cream, hair care, lotions, facial scrubs -- you name it! They don't just increase scrubbing power: small, round, squishy microplastics are mixed in with gels and lotions to make them feel smoother (Plastic Soup Foundation, 2022; Simon, 2022).
\nSecondary microplastics aren't intentionally small, they're just pieces of larger plastic products that have broken down. Plastic bags, bottles, and packaging shed pieces of themselves as flakes or strands, and then they just… don't go away.
\nAnd that's the problem. Plastics are bioresistent and biopersistent, meaning there are very few natural processes that degrade plastics
\nWhen you try to break it apart, it's like a Minecraft slime: it just breaks into smaller and smaller pieces of itself.
\nAnd as they break apart into smaller and smaller pieces, they're tumbling through their environment and they're collecting whatever pathogens and pollutants are there. Like a snowball rolling down a hill, the longer a piece of microplastic tumbles through its environment, the more crap it collects (Enyoh et al., 2019; Simon, 2022).
\nScientists have found that microplastic pollution accumulates a wide variety of things: pharmaceuticals like ibuprofen, heavy metals like lead and mercury, and forever chemicals like PFASs. It's such a thriving little cocktail of bad chemicals and microbes that scientists have coined the term "plastisphere" to describe the microbiome that builds on plastic (Picó et al., 2020; Simon, 2022).
\nAfter tumbling through the environment and collecting a bunch of pollutants, microplastic pollution most commonly ends up in our waterways and the ocean, where it then infiltrates the food chain.
\nIn the ocean, phytoplankton form the base of the food chain. Phytoplankton are tiny organisms that photosynthesize like plants to get their energy. Primary consumers like small fish and crustaceans eat the phytoplankton and then predators like larger fish eat the smaller fish and crustaceans.
\nThe problem is that the primary consumers will confuse microplastics for phytoplankton and eat those instead
\nThe first problem with that is that the plastic obviously doesn't have any nutritional value, but it makes them feel full. It's like eating a salad that's partially glitter and plastic beads. It may fill you up quicker, but the plastic will just go right through you. We see fish that eat plastic don't end up growing as large as they should (Simon, 2022)
\nThe second problem is that they're eating a salad full of glitter and plastic beads. It may look pretty, but it's certainly not good for you, especially after those microplastics have accumulated all those chemicals and pollutants that we talked about earlier.
\nAnd the third problem is that microplastics entering the lowest point in the food chain work their way up to the highest point. Not only have scientists found plastic in baby fish (Gove et al., 2019) -- which can stunt their growth or flat out kill them -- but we've found them in the excrement and digestive tracts of larger predators, including whales and walruses in the arctic (Carlsson et al., 2021; Lusher et al., 2015).
\nBut you might be eating your own glitter and plastic bead salad. So much food, including produce from grocery stores and supermarkets, is wrapped in plastic. We know that microplastics get into food through plastic packaging. That is, if it hasn't already been contaminated during its production (Kosuth et al., 2018). This "clean" plastic hasn't had the time to accumulate a plastisphere like plastic pollution, but it can still be problematic because of the chemicals they're made from.
\nI want to give a disclaimer here: we don't really know the full effects that plastics and microplastics have on our health yet. But there is a lot that we do know, and it paints a concerning picture.
\nWe know that some of the most common chemicals added to plastics -- phtalates and bisphenols especially -- are known as "endocrine disrupting chemicals," or EDCs. These EDCs throw off the hormone balance in humans, and can cause problems with your heart, brain, immune system, reproductive system -- it's a mess (Ong et al., 2020; Simon, 2022; Williams & Rangel-Buitrago, 2022).
\nWe know that we're eating plastics, either because they were in the animals we consumed or because it leeched in through the packaging and production process. (Kosuth et al., 2018; Zhang et al., 2021)
\nWe know that we're drinking plastics, from a 2017 report that found plastic in 83% of tap water samples around the world (Kosuth et al., 2017). That report indicated that plastic contamination was worst in North America.
\nWe know that we're inhaling microplastics in the very air around us. Indoor environments can have up to 1,000 microplastic per gram of dust in the air, and one study estimates that adults inhale about 20 microplastics per day (Zhu et al., 2022).
\nWhether by inhaling or eating or something else, we know that plastics get into our blood, where they may be leaching chemicals and heavy metals straight into our bloodstream (Simon, 2022; Song et al., 2024; Zuo et al., 2024)
\nSome scientists have speculated that microplastics could be contributing to the rises we're seeing in cardiac and neurological health issues, although there's no direct link for that right now (Simon, 2022).
\nThe majority of these microplastics in the air come from our clothing -- a significant portion of clothing is made from polyester and nylon, which are plastics.
\nDoing just a single load of laundry releases tons of microplastic fibers into the air and our sewage systems (Kacprzak & tijing, 2022; Simon, 2022).
\nBut think of how many other things in your home are made of plastic. Even things like flooring, upholstery, and paints are made from plastics, and they shed particles every time you use them.
\nOutdoors is a lot better, but it's still not perfect. Urban environments tend to have less than 100 microplastics per gram of [dust in the] air, compared to the over 1,000 of indoor air (Zhu et al., 2022). Microplastics in the atmosphere come from countless sources. Wear and tear from our clothing is part of it, but a huge source is tires. As your tire tread wears down, it's flinging millions of tiny particles of rubber into the atmosphere, contributing to the almost 4 billion pounds of rubber microplastics that the US generates per year from driving (Kole et al., 2017).
\nWe also know that a common thread seems to be that exposure is higher for children and babies. Plastic baby bottles are a huge source of this, but children are also just lower to the ground, where dust is being stirred up and settling (Zhu et al., 2022). Not even to mention that microplastics are being passed on to newborn babies from their mothers (Sun et al., 2024; Simon, 2022).
\nThis is getting out of hand, these microplastics are coming from everywhere, we don't know how they affect us yet, how can we stop this?
\nSo how can we stop this?
\nThe truth is, on a personal level, you just can't avoid exposure to microplastics. But the good news is there are things you can do to reduce your personal exposure.
\nCut out single-use plastics as best you can, replace plastic tools in your home with ones made from natural materials like wood, wear long-lasting clothes made from natural materials like wool and cotton, vacuum and clean regularly (Kacprzak & Tijing, 2022). You can get a HEPA air filter to help keep the air in your home clean, or getting an aftermarket filter for your washing machine can help keep pollution out of our waterways.
\nBut all of this is just picking glitter out of the salad, we should really just… stop putting glitter and plastic beads in the salad.
\nThis is going to take global collaboration and policy to really fix.
\nPlastic is so ubiquitous in the environment that it's been suggested as a geological indicator of human activity. Plastic production is only set to increase unless something changes, and about half of that new plastic production will end up in landfills or in the environment. That's only going to make our microplastics problem exponentially worse (Williams & Rangel-Buitrago, 2022).
\nSo what policy should we be enacting?
\nWe can incentivize the development of technology as part of the solution. There are already some really cool technologies being developed.
\nBioplastics currently make up a tiny portion of global plastic production, but it is a growing sector. Bioplastics are plastics that are made from carbon sources other than fossil fuels, or that are biodegradable (Williams & Rangel-Buitrago, 2022). Of those two, biodegradable is obviously preferred, but even that has its caveats, so it's only really a small part of the total solution.
\nAnother solution is barriers to help filter litter and pollution out of waterways before they reach a larger body of water. A great solution here comes from a Dutch company by the name of The Great Bubble Barrier. They have deployed an incredibly simple solution to pollution filtering. They run a PVC pipe with holes in it under a waterway and then just pump air through the pipes. The bubbles allow fish and ships to pass through, but they catch and redirect floating pollution into collection bins (Williams & Rangel-Buitrago, 2022; https://thegreatbubblebarrier.com).
\nAnother thing would be improving the treatment technology for wastewater and drinking water plants around the world. That could help filter out microplastics from laundry and drinking water. We actually already have the technology to significantly improve treatment in these sectors, but we're just not investing in making it happen, partially because of larger, systemic issues of inequity (Simon, 2022).
\nBut one of the coolest solutions that you may of heard of is "plastic-eating microbes." That's not quite accurate, though -- scientists are genetically engineering microbes to produce an enzyme that breaks down plastic into its parts (Fohler et al., 2024). There are a lot of issues facing this before it can be deployed at scale, but this is one of the most promising options for the future, in my opinion, because the enzyme breaks plastic down so cleanly that it can be recycled with almost no loss in quality.
\nBut all of these solutions are at best flex taping together a boat that was sawed in half. What we really need to do is take the saw away from the maniac who's cutting boats in half. We need to decide as a society to hold corporations accountable. In 2022, the US alone just flat-out gave the plastic and oil industry $3 billion in subsidies, but they also undercharged them for environmental costs to the tune of $757 billion (Black, 2023).
\nAnd that trend extends globally, resulting in $7 trillion in total subsidies for oil and plastic in 2022 (Black, 2023).
\nWe're at least keeping glitter out of the salad now, but let's stop the people who keep spilling it in.
\nSo we need to be banning single-use plastics, placing restrictions on plastic packaging, hold the plastic industry responsible for the entire lifecycle of their product. The plastic companies aren't just gonna fix the problem on their own, they're too busy making money. So we need to be coming up with solutions or, even better, forcing these plastic companies to solve the problem they've created. They can't just get away with filling up our rivers, ourforests, and our own bodies with plastic.
\nIn a more and more divided world, this is not a partisan issue, so we need to be getting involved in our local and federal politics and pressuring our representatives to pass policies that help everyone out.
\nAt this point, it's hard to imagine a life without plastic. Even though we got by just fine without plastic 100 years ago, I don't see us going back to that. And after all, plastic has plenty of merits -- plastics have saved countless lives in its various uses in the medical industry, and it's made access to technology more equitable.
\nBut we can't keep doing this. Sustainability isn't about going back to the 1900s, it's about finding a compromise between modern convenience, and not destroying our own health and the planet. We can find a middle ground, but it's going to be a world that doesn't maximize convenience.
\nAnother big barrier to plastic policy that we've found is just lack of public awareness of the issue (Kacprzak & Tijing, 2022). So share this video, talk about microplastics with your friends. If this video made you uncomfortable at just much we're surrounded by plastic, take that and use it to help us change, help us build a more sustainable world.

\nWatch the short here: https://youtube.com/shorts/0dUTFR-eCAA
\nThis is a very complex topic, and I didn't have the time to research nor write about all of it. If you're here, it means you're probably looking for extra context, so here are the main things I want to clarify:
\nThe 12.3 billion litres for power generation is a rough estimate. A lot of these tech companies produce some of their own power, and almost all of them technically run on "100% renewable energy" (but that's mostly accomplished through Power Purchase Agreements (PPAs) and other things that make it work on paper, but it's not literally true). It also uses some averages from Jin et al. (2019), some of which have broad data points (namely hydropower).
\nAll power generation plants and all data centers are different. They all have different means of cooling, which means different rates of water consumption. But my point for this video isn't to get into the nuance, it's to point out that in the big picture, this is a problem and will continue to be for the foreseeable future unless we push back.
\nFunny enough, I'm not actually 100% on where I stand with AI. I don't like it under capitalism because it's hyper-exploitative of artists and the environment, but I'm not totally sure if I believe it's "plagiarism." What I do know is that most AI models (that get used) were trained on data without the artists' consent, and I am NOT a fan of that.
\nMinor thing, I accidentally referenced the same EPRI article as both 1 and 8 in the video. That's all.
\nCalifornia is on fire again, and this time, part of the blame may be on AI and ChatGPT.
\nYou may have heard some talk about how AI uses so much water, but how does it do that? Why is the computer so thirsty? I thought water was bad for computers?
\nThe answer is that water is consumed at multiple steps in the process of plagiarizing the hard work of artists (Wang, 2024)!
\nBut even before Chat GPT steals my juicy tumblr Supernatural fanfic, water is consumed in manufacturing all the GPUs and other hardware that AI servers need to function.
\nThen, once the servers are up and running, most large datacenters have water cooling towers on the roof that consume lots of water. These work by basically transferring the heat energy from the servers into the water and letting it evaporate off (Li et al., 2023; Mytton, 2021).
\nInside the datacenter, the computers turn electricity into plagiarism; and generating that electricity takes water too! Most electricity is generated by steam generators. Fossil fuels are burned to heat water and generate steam. The steam rises and spins turbines to generate power, but then the steam needs to be cooled down. So a lot of facilities use water to cool the water.
\nA lot of plants use "once-through" cooling systems, where they pull cool water from a river or lake, but then they release that water back after it's absorbed some of the heat. These systems have high water "withdraw," but they actually have very low water "consumption."
\nThe steam that's in the loop is considered "consumed," but that's not much because it's in a closed loop, so it's recirculated. Most of the consumption comes from plants that use evaporative cooling-- that's like the cooling towers on the data centers (Jin et al., 2019; Rathi, 2018; Union of Concerned Scientists, 2010).
\nBut that's just steam generators. Big picture, how much water and electricity does AI consume, and how might that have affected the California wildfires?
\nWell, per-request, AI uses about TEN TIMES as much electricity as a regular Google search, and that's only for LLMs like ChatGPT. AIs that generate /images, video, and music take WAY more than that (EPRI, 2024).
\nFor every watt of electricity used, heat is generated that you need water to cool. That's why energy usage and water usage are so tightly correlated.
\nAnd both of them are growing pretty quickly at every major tech company, with Google leading the way, consistently growing their usage of water and electricity about 15-20% year-over-year (Apple, 2024; Google, 2024; Meta, 2024; Microsoft, 2024)
\nIt's not hard to draw a line between the rise in AI and these growing numbers, but Google themselves even attribute a lot of this growth to expansion of AI services (Google, 2024).
\nBringing it back to California, we can use math and numbers to estimate that data centers in California consumed about 12.3 BILLION liters of water from energy production alone, so that's not counting server cooling.
\nAnd this comes during a time when water scarcity is increasing and much of the western US is in moderate and severe drought conditions.
\nWith all that dry air and soil, that's why [loop] California is on fire again…

\nThis is a chimera! The chimera is a Greek mythical beast with the body of a lion, a snake for a tail, and a goat's head on its back... for some reason. In Greek mythology, it's a sibling of Cerberus and the hydra. The word has come to mean, in modern times, any creature that's a combination of animals.
\nThese are Chimaeras! They just... have an extra "a" in the name.
\nChimaeras are a class of fish that live deep under water. They're related to rays and sharks, and they're perfect to learn about for spoopy month because they're also called SPOOKFISH and GHOST SHARKS!
\nLike sharks and rays, their skeletons are made completely out of cartilage, and like rays, they have a long, whip-like tail. That snake-like tail might be why they're called "chimeras" -- like the snake tail on the greek chimera.
\nThere are 3 types of ghost sharks, and they're all distinguished by their snoot! There are long-nosed, plow-nosed, and short-nosed chimaeras (Finucci et al., 2020).
\nBut all of their snoots are used for sensing electric signals in the water! Even with their massive eyes, there's not much light to see at about 1000 m below the ocean's surface where they live. To make up for that, they have electroreceptors in their snouts that help with navigation, finding food, and avoiding predators (Bottaro, 2022).
\nThese electroreceptors are called Ampullae of Lorenzini, which... I think I fought that guy in DND once
\nDM: As you guys turn the corner, you see the back of a man wearing a large cloak. He slowly turns. His skin is pale and he bears his fangs -- you recognize him: Ampullae of Lorenzini, level 10 vampire wizard! Roll for initiative!
\nPlayers: Aw man! rolling dice
\nPlayer 1: Nat 20!
\nTheir Ampullae of Lorenzini help them avoid predators, but most chimaeroids also have a venomous spine in their dorsal fin to protect themselves from predator attacks.
\nDr. Didier: "I have probably touched and fondled more ghost sharks than anyone on the planet"
\nThat's Dr. Dominique Didier. She's studied ghost sharks for just over 3 decades
\nShe knows to watch for the spines. In fact, she has ahem "personally observed" them (Didier et al., 2012).
\nIn undergrad, she became interested in ghost sharks when she saw that there wasn't a lot of research on them.
\nDr. Didier: "To find current work, I was delving into work that was published in the early 1900s. And I realized 'wow, there's nothing known about these fish, no one is studying them!'"
\nAnd over the last 28 years, she's helped discover eleven different species of ghost sharks, which is pretty amazing when you consider it's actuALLY TWELVE SHE JUST FOUND ANOTHER ONE
\nDr. Didier: "We're coming to the conclusion that what we thought was this one, global species, Harriotta raleighana, is probably not"
\nHariotta avia, or the Australia narrow-nosed spookfish, used to be thought of as the same thing as Hariotta raleighana. Then this year, a paper that Dr. Didier worked on (Finucci et al., 2024) discovered that some of the populations near Australia and New Zealand are their own, unique species!
\nBut how do you tell one species from another?
\nThere are 2 main ways these researchers proved that this is a distinct species. The first one is taking detailed measurements known as morphometrics. For each specimen, the researchers took 64 different morphometric measurements (Finucci et al., 2024).
\nDr. Didier: "I get just piles of fish. I'll go to a museum and just measure all day long measuring and measuring and measuring. We use different things like calipers and forceps, tape measures if it's really big because there's just no device that can capture that whole size. But yeah, that's what we do. And then write it down, put it in our spreadsheets and analyze it."
\nGenetic analysis also played a role in identifying the new species
\nDr. Didier: "Now we have a lot more evidence, partly because we can do molecular studies to say, "this is probably something new""
\nThis figure from the study maps some of the genetic mutations between individual specimens, and you can clearly see that the Harriotta avia specimens are very different from the rest of the Harriotta specimens collected.
\nGiven the morphological and genetic data, the team was able to confidently declare the new species.
\nWhen a new species is declared, a few things generally happen. Most importantly, something needs to describe the species, pretty much always a scientific paper. In this case, that's obviously that Finucci et al. 2024 paper that provides morphometrics and a physical description. That provides documentation of the unique traits of this species.
\nNext, a holotype and paratypes need to be defined. The holotype is the definitive, "name-bearing representative of a new speices" (AMNH, 2015). In other words, this is what peak Harriotta avia performance looks like.
\nHis name is NMNZ: P.061676. Isn't that cute??
\nThat's a specimen identifier for the Museum of New Zealand Te Papa Tongarewa, so other researchers can identify the actual physical thing in the museum's catalog.
\nThe paratypes are basically alternates or supplemental to the holotype. They help provide a more complete picture of a species definition, and they might end up replacing the holotype if it ever gets lost or damaged.
\nMe: Before I let you go, I have to ask one more question: what's your favorite thing about these weird little guys, about ghost sharks?
\nDr. Didier: "Oh my gosh, there's so much to love about them! I just think they're, like, cool to look at! They're ancient, so looking at their anatomy can give us clues to the evolution of vertebrates, which some people are doing! They're weird-looking, they have these strange snouts and sensory systems. We still know very little about their reproduction, where the little guys are. So even now, after working with them for decades, there's still, like, tons of stuff to be done! So that's why I like them, I get excited about all this neat stuff"
\nMe: Is there anything else you want to share for the end of the video?
\nDr. Didier: Coming up, on October 30th, is national ghost shark day! So break out your ghost shark juju and have a great day! ... And they should be on the lookout for "ghost sharks of the world," our upcoming book!
\nThank you so much to Dr. Didier for helping out, check out the link in the description for references, and follow for more cool science!

\nH avia looks very similar to H. raleighana overall. But the skin color is distinct, as is some of the morphology -- that is, the shape and structure of the body and its parts.
\nGenetic analysis also played a role in identifying the new species.

\nThere was 1 topic that got cut from the main wetlands video, and that was vernal pools! Vernal pools are a seasonal wetland that are usually about the size of a pond. They dry up in the summer, but over the fall, winter, and spring, amphibians like salamanders, newts, and frogs use them as breeding grounds that are safely isolated from predatory fish. They're super weird and super cool!
\nWait, I almost forgot! There's actually a secret FIFTH option for wetlands, and they're really weird! It's like a shiny wetland!
\nVernal pools are halfway between a bog and a seasonal pond. They form in shallow basins that collect rainwater, but they go through phases of being flooded, waterlogged, and dry (Keeley & Zedler, 1998).
\nOne of the things that makes vernal pools so weird is that the temperature and pH of the water swing wildly throughout the course of the day. The layer of water is usually pretty thin, so conditions can change rapidly based on exposure to sunlight (Keeley & Zedler, 1998).
\nVernal pools flood during the fall from rain and melting snow, and over the course of fall and winter, they play a vital role in the forests around them. You see, amphibians bridge an important gap in the food chain between invertebrates and larger animals (Liles, 2021).
\nAnd every year, all sorts of newts, salamanders, and frogs use vernal pools to lay their eggs for the next generation. Vernal pools provide a safe breeding grounds because they're temporary and they're isolated from freshwater sources that would have fish (Liles, 2021).
\nOver the summer, vernal pools dry up and just look like any ol' patch of land. It's then that they're the most vulnerable -- developers who either don't care or just don't know better will come along and build on top of them.
\nWe're losing vernal pools rapidly: we've already lost over 90% of the vernal pools in California (US EPA, 2024), a state where they used to be incredibly abundant. After all, it's hard to put protections in place for an ecosystem that's only there some of the time.
