A conversation with the author of The Cactus Hunters: Desire and Extinction in the Illicit Succulent Trade

It was questionable if we needed a second season of Tiger King — or, let’s be honest, a first season. Regardless, if Netflix ever decides it’s interested in a story that features surprisingly charming criminals, IWT violations, and yes, even possibly murder (but without the tabloid tone and mullets), producers might look in the future to Jared D. Margulies’ delightful debut, The Cactus Hunters: Desire and Extinction in the Illicit Succulent Trade.
Wait, illicit succulent trade? you might be wondering. Oh yes.
From the cliffs of California and the deserts of Brazil to the markets of Seoul and the private greenhouses of Czechia, Margulies follows the extraction and relocation of plants so rare that they might only exist in one valley or mountainside in the world. Weaving in ample philosophy and research about what drives these sorts of obsessions — as well as his personal reflections as he, in turn, is captivated by the lovable, spiky plants — The Cactus Hunters is just the right balance of edgy and academic.
Last week, I caught up with Margulies about the process of researching the book, being mistaken for an undercover cop by his subjects, and the lie that is “the green thumb,” among other topics. Our conversation has been edited and condensed for clarity.
You open The Cactus Hunters with a story about how you were going to study the illegal trade of tiger bones when you came across a story about saguaro cactus rustling that piqued your interest and sent you on this journey. What most stands out to you as the differences between the illegal trade of animals and animal products and the world of illegal cactus trading?
To clarify, I never actually got around to studying the illegal trade in tiger bones. I had encountered it a little bit in my past research on human-wildlife conflicts.
But there are a lot of important differences: One of the things that made the illegal plant trade so interesting to study, compared to illegal trade in animals, is that it receives a lot less attention, so there was just a lot more to learn that people hadn’t already researched. But also, the way that this material and these plants can move around the world — there are so many more options available because of the nature of plants. So if what you’re after is the genetics of the plant, to be able to grow them somewhere else in the world, there’s not just the one plant but there’s the cacti propagate, for instance. Pups. Their seeds. You can make cuttings of plants. None of these things are really available to people interested in illegal trade and animals. That affects supply chains and how these things can move around the world.
Also, because of the lack of attention to illegal plant trade compared to animal trade, the subject is a lot less criminalized. I would argue that my access to informants and research participants was a lot better because it did happen that, every now and then, people thought I was a cop. Or maybe, like, an undercover detective. But usually within pretty short order, they realized that wasn’t the case and I was generally interested in trying to understand their perspectives. I think that it would be a lot harder to develop trust within certain trades that are a lot more heavily criminalized.
Over the course of the book, you encounter the Indiana Jones of plants and the Robin Hood of cacti, among others. Can you talk a little about why these enthusiasts, who clearly care deeply about conservation, sometimes break the law by smuggling seeds or entire cacti out of the places where they naturally grow?
One of the fascinating things that really gripped me was this seeming contradiction, where you have people who are made out as conservation villains by certain actors seeing themselves as unsung conservation heroes. The reason for that is, for a lot of these collectors, they saw their community as really passionate people who wanted to get access to the plants that become objects of their desires. By and large, the people who want these plants aren’t trying to do harm to the species in the world, and they care a lot about them. But they also recognize that in their desire is something fairly insatiable and that people are going to go to lengths to get the plant that they have to go to.
For a lot of these collectors, they might see engaging in a kind of illegal activity as still a socially acceptable behavior, if it meant it got material out into the world in a way that people might want it. And the goal there, the long-term goal, is to try to reduce demand on wild harvesting of plants and wild populations. If you get a little bit of material out into the communities that delight in these plants, then you can start grafting them, propagating them, growing them from seed, and, in theory, get that material out into the world.
I wanted to take that perspective seriously. It’s a hard thing to study empirically and so it was important for me to try to be open to a really diverse set of opinions about the right way to do conservation.
You leave most of the sources in the book, including those working within the law, anonymous. Why did you make that decision?
The really short answer is, I was part of a larger research project called BIOSEC, which was run by Professor Rosaleen Duffy at the University of Sheffield in the Department of Politics and International Relations, and we were using a fairly symmetrical ethics approval process, or what in the U.S. we would call an institutional review board approval. Because a number of us were studying illicit economies, in order to ensure research-subject protection and anonymity and security, we were required to make all of our sources anonymous.
But this caused some issues because, on the one hand, it meant that everyone in the book is anonymous, even if they’re people who are law enforcement officials or botanists who would have probably really enjoyed having their names in the book. I regret that.
Most interesting, though, were the number of collectors who were mad at me because they’re also anonymous. One of the reasons for that was they saw anonymity as being suggestive of wrongdoing and for a lot of these people, they don’t feel like what they’re doing is wrong, necessarily, even if it’s against the law. They wanted their story told. I think one of the reasons I had good access to the kinds of interlocutors I had was because they felt like I was providing a space for them to get their version of the story out into the world.
You were asked to be an expert witness in a case against a South Korean smuggler who took thousands of plants from the California coast. How do you navigate moments like this, when your position as an illicit trade researcher is perhaps in tension with your own ethical code?
This was a really difficult decision for me, and I write about this. I went back and forth about whether or not to serve as an expert witness, which in this case just required writing a statement. I never had to go to court or, you know, be on a witness stand — thank goodness. But I go back and forth about if I would do it again.
I think that in the end, I chose to do it because I realized that my testimony would only serve to probably reduce the sentence that this person was facing. And I don’t say that because I think that what they were doing was okay. It was really bad and really harmful to this species of plant. I just don’t think that criminalization and incarceration actually do rehabilitative work or serve much function. It costs us a lot of money as taxpayers and causes harm.
It was complicated; I guess that’s how I would leave it. I debated whether or not to include [the story] in the book but I felt like, in the end, it would be wrong not to include it. I think that if people eventually found out I had served in that capacity, they might felt like I was trying to not disclose something. But yeah, I have some ambiguous feelings about it. In the end, what I was asked to actually do was very limited: I was just asked to put a value on these plants. But as I wrote in my letter to the judge, that value in monetary terms is such an arbitrary thing. The price of those plants has declined precipitously since I wrote that, and it had already gone down a lot since the person who sold them stole them. How interesting, though, that the court of law — at least in the United States — in order to assess the damage done to the state, it had to be valued in monetary terms.
I really liked the inclusion of the story. It’s interesting for a researcher of illicit and illegal trade to all of a sudden be dragged into the concrete legal system, and have it, you know, ask something of you.
Sometimes academics are hard on ourselves in that we think we put in all this work and do all this writing and no one actually reads it. And that’s not true. People do read your work when you publish it and you should think about who those people might be. They might be district attorneys for the state of California. People will use your work, and you should think from the outset about what the social implications of that might be. It was a big lesson for me.
At the end of the book, you write that your experiences in the cactus and succulent community have left you with hope that meaningful change is possible “not through the repressions of desire but through its celebration.” After spending so much time among people that some might call poachers, what makes you optimistic?
We have so many examples from other illicit economies where prohibition doesn’t work. I am concerned by a tendency to move in that direction. Given that we’re talking about plants — you know, as far as we know, this conversation could be different in 50 years — but we’re not having to really think about the welfare issues of, say, illegal trade in animals. There are pragmatic solutions to these problems. This material could get out into the world so that people who want these plants can get it in a way that doesn’t harm wild-growing species.
There’s still a ways to go in working through regulatory conventions to support those efforts. And importantly, in doing so, supporting the people who should have the most support, which I would argue are the communities in places in the world that have lived with these plants the longest.
I see hopeful promise in this, and I saw a whole lot of love. I really did. I saw a lot of love between people and plants, and what that can do for people in moving into developing more careful relations with plants and other species. I don’t have a large collection of cacti and succulents, but I do have some, and I have like a cactus right now that’s in flower. Do you want to see it?
Yes!
This is where I think it’s fun, to think about what plants can teach us—
Oh, it’s gorgeous!
This is a Mammillaria laui. Named for Alfred Lau, who I write about in one of the chapters of the book — a German who lived in Mexico, who has a lot of different species named after him. This is Mammillaria laui, subspecies subducta. It’s got this gorgeous crown of pink flowers.
I love having these plants. Specifically, I’ve started a small collection of plants that are associated with particular people that I wrote about, or that I thought about. Bringing some of that social history to our plants, I think, is a really nice thing that people can do. Learn about where our plants come from and the histories of how they got to where we are.
That’s kind of what set me off on this whole journey, anyway. I think there’s a lot of opportunity for thinking thoughtfully about the place of these plants in the world and how they travel and maybe, hopefully, that can help move us towards a more ethical kind of relation.
Are you worried now that once you collect all of the plants that are connected to your book, you’ll throw your whole collection out?
I don’t think I have a strong collector tendency, per se. I have been accused of being a low-key hoarder before. I’m excited to think about how I’m going to slowly develop a collection over time. Yeah, but your reference — the worst thing that can happen to a collector is completing a collection. Freud wrote about this in the context of completing his collection of statues and dying days later. This one collector who I went to see, I thought I was going to see a giant greenhouse of cacti, but I found a bunch of Mexican chili plants. Because he’d just tossed [the cacti collection] off, he was done with it. I don’t see myself going down that road but one never knows.
For someone reading this interview who might be interested in collecting, where would you say to start?
We need to get over this idea that cacti and succulent plants are great house plants because they don’t require any care. It’s not true. Everyone I know who’s had a succulent has killed it very quickly.
I killed mine.
Yeah, if you just throw a succulent on, like, a north-facing windowsill, it’s not going to do well, especially if you ignore it.
Also, get over the idea that there are natural people in the world with a green thumb — I think that is also nonsense. We just need to spend time learning about what these plants need. One of the ways you can do that is by paying attention to them.
In terms of obtaining material — you know, so much plant material can also just be found for free, gifted from friends or colleagues or the community. A lot of collector clubs, like, say, the Cactus and Succulent Society of America here in the U.S., I believe may even send you free seeds of cacti, and stuff like that.
The thing that I want to start doing is trying to grow cacti from seed. They’re slow-growing plants but I think it’d be really fun to actually watch that process unfold. And it’s quite easy to obtain seeds for a lot of these plants. Just, you know, be careful where you’re buying stuff from. Reputable nurseries are a good source. But be wary of buying from unknown people on the internet. That might be where people start to get into trouble.
Is there anything I haven’t asked you about that you’d like to let me know about your book or your experience writing it before I let you go?
I’m not too prescriptive at the end of the book about what I think the answer is. Some people may find that frustrating, like, “Oh, but you didn’t tell us like what should we do” or “What’s the right response?” One of the reasons for that was I just wanted to let people develop some of their own thoughts about this. But also it’s because the work isn’t done.
I’m developing some work right now dealing with illegal succulent trade in South Africa with some colleagues, both in South Korea but also in South Africa. I’m doing a new project on illicit Venus flytrap harvesting and the carnivorous plant trade. I’m trying to continue the process of thinking and learning with plants. But the work continues.

A federal judge in Massachusetts ruled that construction on Vineyard Wind could proceed.
The Vineyard Wind offshore wind project can continue construction while the company’s lawsuit challenging the Trump administration’s stop work order proceeds, judge Brian E. Murphy for the District of Massachusetts ruled on Tuesday.
That makes four offshore wind farms that have now won preliminary injunctions against Trump’s freeze on the industry. Dominion Energy’s Coastal Virginia offshore wind project, Orsted’s Revolution Wind off the coast of New England, and Equinor’s Empire Wind near Long Island, New York, have all been allowed to proceed with construction while their individual legal challenges to the stop work order play out.
The Department of the Interior attempted to pause all offshore wind construction in December, citing unspecified “national security risks identified by the Department of War.” The risks are apparently detailed in a classified report, and have been shared neither with the public nor with the offshore wind companies.
Vineyard Wind, a joint development between Avangrid Renewables and Copenhagen Infrastructure Partners, has been under construction since 2021, and is already 95% built. More than that, it’s sending power to Massachusetts customers, and will produce enough electricity to power up to 400,000 homes once it’s complete.
In court filings, the developer argued it was urgent the stop work order be lifted, as it would lose access to a key construction boat required to complete the project on March 31. The company is in the process of replacing defective blades on its last handful of turbines — a defect that was discovered after one of the blades broke in 2024, scattering shards of fiberglass into the ocean. Leaving those turbine towers standing without being able to install new blades created a safety hazard, the company said.
“If construction is not completed by that date, the partially completed wind turbines will be left in an unsafe condition and Vineyard Wind will incur a series of financial consequences that it likely could not survive,” the company wrote. The Trump administration submitted a reply denying there was any risk.
The only remaining wind farm still affected by the December pause on construction is Sunrise Wind, a 924-megawatt project being developed by Orsted and set to deliver power to New York State. A hearing for an injunction on that order is scheduled for February 2.
Noon Energy just completed a successful demonstration of its reversible solid-oxide fuel cell.
Whatever you think of as the most important topic in energy right now — whether it’s electricity affordability, grid resilience, or deep decarbonization — long-duration energy storage will be essential to achieving it. While standard lithium-ion batteries are great for smoothing out the ups and downs of wind and solar generation over shorter periods, we’ll need systems that can store energy for days or even weeks to bridge prolonged shifts and fluctuations in weather patterns.
That’s why Form Energy made such a big splash. In 2021, the startup announced its plans to commercialize a 100-plus-hour iron-air battery that charges and discharges by converting iron into rust and back again. The company’s CEO, Mateo Jaramillo, told The Wall Street Journal at the time that this was the “kind of battery you need to fully retire thermal assets like coal and natural gas power plants.” Form went on to raise a $240 million Series D that same year, and is now deploying its very first commercial batteries in Minnesota.
But it’s not the only player in the rarified space of ultra-long-duration energy storage. While so far competitor Noon Energy has gotten less attention and less funding, it was also raising money four years ago — a more humble $3 million seed round, followed by a $28 million Series A in early 2023. Like Form, it’s targeting a price of $20 per kilowatt-hour for its electricity, often considered the threshold at which this type of storage becomes economically viable and materially valuable for the grid.
Last week, Noon announced that it had completed a successful demonstration of its 100-plus-hour carbon-oxygen battery, partially funded with a grant from the California Energy Commission, which charges by breaking down CO2 and discharges by recombining it using a technology known as a reversible solid-oxide fuel cell. The system has three main components: a power block that contains the fuel cell stack, a charge tank, and a discharge tank. During charging, clean electricity flows through the power block, converting carbon dioxide from the discharge tank into solid carbon that gets stored in the charge tank. During discharge, the system recombines stored carbon with oxygen from the air to generate electricity and reform carbon dioxide.
Importantly, Noon’s system is designed to scale up cost-effectively. That’s baked into its architecture, which separates the energy storage tanks from the power generating unit. That makes it simple to increase the total amount of electricity stored independent of the power output, i.e. the rate at which that energy is delivered.
Most other batteries, including lithium-ion and Form’s iron-air system, store energy inside the battery cells themselves. Those same cells also deliver power; thus, increasing the energy capacity of the system requires adding more battery cells, which increases power whether it’s needed or not. Because lithium-ion cells are costly, this makes scaling these systems for multi-day energy storage completely uneconomical.
In concept, Noon’s ability to independently scale energy capacity is “similar to pumped hydro storage or a flow battery,” Chris Graves, the startup’s CEO, told me. “But in our case, many times higher energy density than those — 50 times higher than a flow battery, even more so than pumped hydro.” It’s also significantly more energy dense than Form’s battery, he said, likely making it cheaper to ship and install (although the dirt cheap cost of Form’s materials could offset this advantage.)
Noon’s system would be the first grid-scale deployment of reversible solid-oxide fuel cells specifically for long-duration energy storage. While the technology is well understood, historically reversible fuel cells have struggled to operate consistently and reliably, suffering from low round trip efficiency — meaning that much of the energy used to charge the battery is lost before it’s used — and high overall costs. Graves conceded Noon has implemented a “really unique twist” on this tech that’s allowed it to overcome these barriers and move toward commercialization, but that was as much as he would reveal.
Last week’s demonstration, however, is a big step toward validating this approach. “They’re one of the first ones to get to this stage,” Alexander Hogeveen Rutter, a manager at the climate tech accelerator Third Derivative, told me. “There’s certainly many other companies that are working on a variance of this,” he said, referring to reversible fuel cell systems overall. But none have done this much to show that the technology can be viable for long-duration storage.
One of Noon’s initial target markets is — surprise, surprise — data centers, where Graves said its system will complement lithium-ion batteries. “Lithium ion is very good for peak hours and fast response times, and our system is complementary in that it handles the bulk of the energy capacity,” Graves explained, saying that Noon could provide up to 98% of a system’s total energy storage needs, with lithium-ion delivering shorter streams of high power.
Graves expects that initial commercial deployments — projected to come online as soon as next year — will be behind-the-meter, meaning data centers or other large loads will draw power directly from Noon’s batteries rather than the grid. That stands in contrast to Form’s approach, which is building projects in tandem with utilities such as Great River Energy in Minnesota and PG&E in California.
Hogeveen Rutter, of Third Derivative, called Noon’s strategy “super logical” given the lengthy grid interconnection queue as well as the recent order from the Federal Energy Regulatory Commission intended to make it easier for data centers to co-locate with power plants. Essentially, he told me, FERC demanded a loosening of the reins. “If you’re a data center or any large load, you can go build whatever you want, and if you just don’t connect to the grid, that’s fine,” Hogeveen Rutter said. “Just don’t bother us, and we won’t bother you.”
Building behind-the-meter also solves a key challenge for ultra-long-duration storage — the fact that in most regions, renewables comprise too small a share of the grid to make long-duration energy storage critical for the system’s resilience. Because fossil fuels still meet the majority of the U.S.’s electricity needs, grids can typically handle a few days without sun or wind. In a world where renewables play a larger role, long-duration storage would be critical to bridging those gaps — we’re just not there yet. But when a battery is paired with an off-grid wind or solar plant, that effectively creates a microgrid with 100% renewables penetration, providing a raison d’être for the long-duration storage system.
“Utility costs are going up often because of transmission and distribution costs — mainly distribution — and there’s a crossover point where it becomes cheaper to just tell the utility to go pound sand and build your power plant,” Richard Swanson, the founder of SunPower and an independent board observer at Noon, told me. Data centers in some geographies might have already reached that juncture. “So I think you’re simply going to see it slowly become cost effective to self generate bigger and bigger sizes in more and more applications and in more and more locations over time.”
As renewables penetration on the grid rises and long-duration storage becomes an increasing necessity, Swanson expects we’ll see more batteries like Noon’s getting grid connected, where they’ll help to increase the grid’s capacity factor without the need to build more poles and wires. “We’re really talking about something that’s going to happen over the next century,” he told me.
Noon’s initial demo has been operational for months, cycling for thousands of hours and achieving discharge durations of over 200 hours. The company is now fundraising for its Series B round, while a larger demo, already built and backed by another California Energy Commission grant, is set to come online soon.
While Graves would not reveal the size of the pilot that’s wrapping up now, this subsequent demo is set to deliver up to 100 kilowatts of power at once while storing 10 megawatt-hours of energy, enough to operate at full power for 100 hours. Noon’s full-scale commercial system is designed to deliver the same 100-hour discharge duration while increasing the power output to 300 kilowatts and the energy storage capacity to 30 megawatt-hours.
This standard commercial-scale unit will be shipping container-sized, making it simple to add capacity by deploying additional modules. Noon says it already has a large customer pipeline, though these agreements have yet to be announced. Those deals should come to light soon though, as Swanson says this technology represents the “missing link” for achieving full decarbonization of the electricity sector.
Or as Hogeveen Rutter put it, “When people talk about, I’m gonna get rid of all my fossil fuels by 2030 or 2035 — like the United Kingdom and California — well this is what you need to do that.”
On aluminum smelting, Korean nuclear, and a geoengineering database
Current conditions: Winter Storm Fern may have caused up to $115 billion in economic losses and triggered the longest stretch of subzero temperatures in New York City’s history • Temperatures across the American South plunged up to 30 degrees Fahrenheit below historical averages • South Africa’s Northern Cape is roasting in temperatures as high as 104 degrees.

President Donald Trump has been on quite a shopping spree since taking an equity stake in MP Materials, the only active rare earths miner in the U.S., in a deal Heatmap’s Matthew Zeitlin noted made former Biden administration officials “jealous.” The latest stake the administration has taken for the American taxpayer is in USA Rare Earth, a would-be miner that has focused its attention establishing a domestic manufacturing base for the rare earth-based magnets China dominates. On Monday, the Department of Commerce announced a deal to inject $1.6 billion into the company in exchange for shares. “USA Rare Earth’s heavy critical minerals project is essential to restoring U.S. critical mineral independence,” Secretary of Commerce Howard Lutnick said in a statement. “This investment ensures our supply chains are resilient and no longer reliant on foreign nations.” In a call with analysts Monday, USA Rare Earth CEO Barbara Humpton called the deal “a watershed moment in our work to secure and grow a resilient and independent rare earth value chain based in this country.”
After two years of searching for a site to build the United States’ first new aluminum smelter in half a century, Century Aluminum has abandoned its original plan and opted instead to go into business with a Dubai-based rival developing a plant in Oklahoma. Emirates Global Aluminum announced plans last year to construct a smelter near Tulsa. Under the new plan, Century Aluminum would take a 40% stake in the venture, with Emirates Global Aluminum holding the other 60%. At peak capacity, the smelter would produce 750,000 tons of aluminum per year, a volume The Wall Street Journal noted would make it the largest smelter in the U.S. Emirates Global Aluminum has not yet announced a long-term contract to power the facility. Century Aluminum’s original plan was to use 100% of its power from renewables or nuclear, Canary Media reported, and received $500 million from the Biden administration to support the project.
The federal Mine Safety and Health Administration has stopped publishing data tied to inspections of sites with repeated violations, E&E News reported. At a hearing before the House Education & the Workforce Subcommittee on Workforce Protections last week, Wayne Palmer, the assistant secretary of labor for mine safety and health, said the data would no longer be made public. “To the best of my knowledge, we do not publish those under the current administration,” Palmer said. He said the decision to not make public results of “targeted inspections” predated his time at the agency. The move comes as the Trump administration is pushing to ramp up mining in the U.S. to compete with China’s near monopoly over key metals such as rare earths, and lithium. As Heatmap’s Katie Brigham wrote in September, “everybody wants to invest in critical minerals.”

South Korea’s center-left Democratic Party has historically been staunchly anti-nuclear. So when the country’s nuclear regulator licensed a new plant earlier this month — its first under a new Democratic president — I counted it as a win for the industry. Now President Lee Jae-myung’s administration is going all in all on atomic energy. On Monday, NucNet reported that the state-owned Korea Hydro & Nuclear Power plans to open bidding for sites for two new large reactors. The site selection is set to take up to six months. The country then plans to begin construction in the early 2030s and bring the reactors online in 2037 and 2038. Kim Sung-whan, the country’s climate minister, said the Lee administration would stick to the nuclear buildout plan authored in February 2025 under former President Yoon Suk Yeol, a right-wing leader who strongly supported the atomic power industry before being ousted from power after attempting to declare martial law.
Reflective, a nonprofit group that bills itself as “aiming to radically accelerate the pace of sunlight reflection research,” launched its Uncertainty Database on Monday, with the aim of providing scientists, funders, and policymakers with “an initial foundation to create a transparent, prioritized, stage-gated” roadmap of different technologies to spray aerosols in the atmosphere to artificially cool the planet. “SAI research is currently fragmented and underpowered, with no shared view of which uncertainties actually matter for real-world decisions,” Dakota Gruener, the chief executive of Reflective, said in a statement. “We need a shared, strategic view of what we know, what we don’t, and where research can make the biggest difference. The Uncertainty Database helps the field prioritize the uncertainties and research that matter most for informed decisions about SAI.” The database comes as the push to research geoengineering technologies goes mainstream. As Heatmap’s Robinson Meyer reported in October, Stardust Solutions, a U.S. firm run by former Israeli government physicists, has already raised $60 million in private capital to commercialize technology that many climate activists and scientists still see as taboo to even study.
Often we hear of the carbon-absorbing potential of towering forest trees or fast-growing algae. But nary a word on the humble shrub. New research out of China suggests the bush deserves another look. An experiment in planting shrubs along the edges of western China’s Taklamakan Desert over the past four decades has not only kept desertification at bay, it’s made a dent in carbon emissions from the area. “This is not a rainforest,” King-Fai Li, a physicist at the University of California at Riverside, said in a statement. “It’s a shrubland like Southern California’s chaparral. But the fact that it’s drawing down CO2 at all, and doing it consistently, is something positive we can measure and verify from space.” The study provides a rare, long-term case study of desert greening, since this effort has endured for decades whereas one launched in the Sahara Desert by the United Nations crumbled.
