Humans have an enormous impact on planet Earth, but from both an animal welfare and an environmental perspective, perhaps nothing is more important than our diets.
In 2022, more than 82 billion livestock animals were slaughtered for meat, according to the Food and Agriculture Organization of the United States, with the majority of those animals being factory farmed. In addition to enormous animal welfare implications, the practice of farming animals is estimated to account for somewhere between 11% and 20% of all greenhouse gas emissions.
All things considered, what is the most ethical diet? According to utilitarian moral philosopher Peter Singer, it’s one that includes zero — or at least very few — animal products.
Singer is among the most influential living philosophers and is widely credited for putting animal ethics on the map with his controversial 1975 book, Animal Liberation. Because most nonhuman animals have the capacity to suffer, Singer argues, we should not exploit their suffering for our own good, particularly with the horrific conditions of practices like factory farming.

More recently, he published an extensively revised version, Animal Liberation Now, which brings to light the brutal living conditions for tens of billions of animals today.
I recently had the pleasure of interviewing Singer and discussing speciesism, the conditions of factory farming and how to have an ethical diet.
You’re widely regarded as the father of the animal rights, or as you may prefer, the animal liberation movement. Can you make your case for the pursuit of animal liberation?
The case for the animal liberation movement is that to disregard or discard the interests of beings because they’re not members of our species is indefensible. I use the term “speciesism” to describe that, and that is intended to make the parallel between other -isms such as racism and sexism that most people — certainly I hope the audience that I’m addressing — reject and say that although the analogy is obviously not complete, in all of these cases there’s been a dominant group which has developed an ideology to enable it to justify using a group that it dominates. In one case, nonwhites, in another case, women, and then in this case, nonhumans. To justify using that group for its own purposes in ways that are clearly very harmful to the group, but somewhat beneficial to the dominant group.
So I think we ought to be able to see that the difference in species is not relevant to how bad it is when a being is suffering, if the being is capable of suffering. What matters is how much the being is suffering, what kind of suffering that is — can we compare it with the suffering that we humans may experience? To some extent, I believe we can. And when we make that comparison, it’s not difficult to see that there are many areas in which we inflict immense suffering on nonhuman animals for either no benefits or minor benefits to humans. So I think it follows from the idea of equal consideration of similar interests — which is a principle that I think should hold irrespective of species — it follows from that that many of the things we do to animals are unjustifiable, and that’s the case for animal liberation, or if people want to so put it in terms of recognizing the rights of animals, or, I would say, the case for equal consideration for similar interests across species.
Should we all become vegan or vegetarian?
I would say not in absolutely all circumstances, but if we’re thinking about the situation of somebody who has the option of nourishing themselves well, having an adequate diet, being healthy without consuming animal products, and if those animal products come from commercial enterprises where there’s a profit motive for not being concerned about the wellbeing of the animal beyond productivity of the enterprise, then I think it does follow that we ought not to be consuming those products.
So as I say, there are various other circumstances — that would be circumstances of people who can’t nourish themselves adequately without eating animal products — they have a much larger sacrifice to make than others. And there may be cases where you’re not getting your animal products from large commercial enterprises where the animals have good lives and are humanely killed that would need separate consideration, but the claim I make is one that obviously applies to billions of people in the world today, so that’s enough, I think, to try to get that changed.
You first published Animal Liberation in 1975. And then in May of 2023, you published an updated version, Animal Liberation Now. Surely, much has changed in terms of factory farming practices, the state of animal welfare, among many other factors. In your view, what are some of the most significant changes since 1975, and what made you decide that it was time to publish a revision of Animal Liberation?
Obviously there has been a lot of changes and that’s why it’s really virtually a new book, rather than just a new edition because I’d say probably about half of the text is new. And not so much on the philosophical argument that I just gave you. I think that that has stood up very well to criticism and discussion. But the two longest chapters of Animal Liberation are largely factual where I’m describing research done on animals, and the other describing factory farm conditions. Those chapters had to be completely rewritten. And then there were other discussions about climate change, for example — which was not on my radar or not on many people’s radars in 1975 — had to be brought in because that’s very relevant to the ethics of eating animal products. And I wanted to talk a bit about the progress that the animal movement has made and the progress that it has not made. So those are important changes to the book, and I wanted to talk about that — the new discussion about ethical questions relating to animals, which again was very much a neglected issue, hardly an issue that anybody touched upon in 1975, but now has quite a major literature. So a lot of different things. And also, I should add, there’s more research on animal sentience. So I think we can have more confidence in saying that fish, for example, are sentient, which is something that some people questioned after the first edition was published. And the sentience of octopuses, and even some crustaceans, like lobsters, I think is now much more firmly established than it was. So there’s been a lot of science that has supported the view that I was taking about animal sentience and actually has extended it.

Peter Singer with a previous version of Animal Liberation, on Sept. 22, 2022. Derek Goodwin Photography
In terms of the most significant changes, well, I think some things have gotten better and some things have gotten worse. I talked about the improvements in regulation of factory farming in a few places, most notably the European Union. Also some states of the U.S., but only a minority, particularly California, which passed stricter legislation. So those are good things, but there have also been negative developments. In the case of the chicken industry — chickens are, by far, the most numerous of the land-based vertebrate animals we raise for food — that’s gotten worse because chickens have been bred to grow even faster. And this causes all sorts of problems for them and causes skeletal abnormalities. And they put on weight so fast now that their legs are immaterial for bearing their weight. Chickens are slaughtered when they’re very, very young birds — about six weeks old when they’re slaughtered. And so they’re really babies and their leg bones just aren’t strong enough to support the weight that they’ve put on because they’ve been bred to eat so much and grow so fast. So there’s actually a new cause of pain to bear. They have difficulty bearing their weight, difficulty standing up and walking around because of how fast they’ve been bred to grow. So there are new developments, like that, that make factory farming even worse in some respects than it was.
You describe yourself as a flexible vegan. So you must believe that there’s at least some wiggle room when it comes to having an ethical diet.
That’s because, you know, my ethics are utilitarian or consequentialist. I’m always looking at the consequences of what I do, and my ethics is not about rigid rules. So for me, being vegan is not like somebody — a religious person — who will only eat halal or kosher meat and will think it doesn’t matter how much non-kosher or non-halal meat you eat. It’s just wrong to do it and the wrong would be as great if you ate more of it or less of it. But for me, I want to not be complicit in supporting these industries that treat animals so badly. And the degree of complicity obviously varies by how much I’m spending — to what extent my dollars are supporting those industries. So if for most of my everyday shopping, I avoid animal products, but sometimes when I’m traveling there’s nothing much to eat that doesn’t have some, you know, something like a dairy product, let’s say in it. It’s not a significant contribution that I’m making, and if it’s going to be really difficult for me to get anything to eat that doesn’t contain an animal product — or if I’m in social circumstances where it would disturb the group if I said no, I can’t eat anything here — I’ll eat something that’s vegetarian but not vegan. So that’s the sense in which I’m flexible.
So for people who recognize the cruelty of factory farms and the climate implications of factory farms, and even the climate implications of organic animal farms, but don’t feel ready to commit fully to veganism or vegetarianism, how can those people eat more ethically?
Well, they can still avoid factory farmed products which I think is really important, because that’s where the vast majority of the suffering we inflict on nonhuman animals is. So I would say, depending on how much you feel you want to eat in terms of animal products, I think if you’re talking about the most affluent countries, including the United States, the animal product that perhaps is most easy to get in a form that is not ideal, but is still acceptable, would be eggs from pasture-raised hens. So if you can find a farm that is producing eggs, and the hens really are out on pasture — it’s not just that they’re cage-free, which still might mean that they’re locked up in a big shed — but they’re actually able to go outside and exercise, chase insects, dust bathe, all of those things that are natural for the hens, then you could at least say, well, if the hens are having a reasonably good life here (and sure they’re going to get killed prematurely, and sure the male chicks of that breed are going to get killed immediately on hatching because they’re of no commercial value), it’s a better product definitely than products from animals who are inside all of their lives, very crowded. So I would start with that.
After that, it does get harder. Many people will say, well, what about dairy products from organically raised cows — cows who are outside on pasture again. And that’s certainly better from an animal welfare point of view — as for that matter is beef from grass-fed cows — but it’s worse for the climate, because cows are ruminants and they emit a lot of methane. And the fact that they’re on grass doesn’t really help in terms of reducing their methane output. It’s still there. And in fact, some studies suggest that with grass-fed beef, it’s actually higher, because if you don’t feed them on grain as most beef is fed, for at least the last six months of their lives, they put on weight more slowly, and so for each pound of beef produced there’s more digesting and more methane produced. So you know, that’s a dilemma. But again, if people say, well, I just want to do this occasionally as I need it, or I’m not prepared to go without it, maybe eating small quantities of grass-raised or pasture-raised dairy or beef products might be the next thing to do.
I understand that you’ve recently stepped back from your teaching role at Princeton. So if you don’t mind sharing, what’s next for you?
Yeah, you’re right, I taught my last semester at Princeton now but I’m I’ve got plenty of opportunities to write, to speak, to give interviews like this one. And I’ve got offers of taking visiting positions in other parts of the world which I plan to do, the first of those probably going to Singapore for about a month during 2024. There are other possible places that I will be going to and speaking out in Europe and possibly in Asia. So yeah, I’m planning to keep pretty busy.
That’s all the questions that I had prepared for you. But I’d also like to ask if there’s anything else you’d like to share? Maybe something that we haven’t touched on that you’d like to add?
Oh, I think we’ve covered quite a lot. Obviously, I have a broader interest in bioethics beyond what we’ve spoken about. And so there are a variety of things I’m interested in and I’m continuing to work with the organization The Life You Can Save, which tries to encourage people to give to the most effective charities helping people in extreme poverty. So I think that’s also an important thing to do. And if people want to know more about my work there, they can have a look at my website, petersinger.info, or also go to thelifeyoucansave.org where they can download a free digital copy or audio copy of my book The Life You Can Save and learn more about my work for people in extreme poverty.

Earth911 Inspiration: Half The Energy and Doing Just Fine
Stewart Brand, who popularized the “blue marble” photograph that changed humanity’s perspective on the fragility of the Earth, points out that Californians and Europeans use half the energy of the typical American, without losing any quality of life. This quote comes from Whole Earth Discipline: Why Dense Cities, Nuclear Power, Transgenic Crops, Restored Wildlands, and Geoengineering Are Necessary, and Brand is also the creator of the Whole Earth Catalog.

Best of Sustainability In Your Ear: Project Repat Is Saving US Jobs & T-Shirts From Landfills
Project Repat, founded by Ross Lohr and Nathan Rothstein, had prevented more than 11 million T-shirts from landfills while bringing some sewing work back to the United States when we talked with them in 2019. They’re still going strong. Tune into a classic conversation as Earth911’s Mitch Ratcliffe talks with Rothstein about the inspiration behind Project Repat and the massive changes in U.S. T-shirt manufacturing over the past 30 years. After migrating to Mexico, T-shirt printing jobs have gone overseas and few American companies still make them.

Project Repat has a better idea: turn old shirts into keepsake quilts hand-sewn using T-shirts sent by customers. Instead of tossing a T-shirt in the donation bin, it can be turned into a part of a memorable and snug quilt. Love a sports team? Make a quilt of the team T-shirts and jerseys you’ve purchased over the years. Want to remember a school or a company where you worked? In all likelihood, you have the makings of a Project Repat quilt. Reasonably priced based on the size, Project Repat takes your order and receives your shirts by mail, then turns them into fleece-backed quilt.

Sustainability In Your Ear: The XPRIZE Wildfire Competition Heats Up
Every wildfire starts small. The problem is that by the time most are detected, minutes have already passed and, under increasingly common conditions driven by a warming climate, a fire can grow beyond any tanker truck’s capacity to contain. The gap between ignition and coordinated response currently averages around 40 minutes. Firefighters have long understood the math: a spoonful of water in the first second, a bucket in the first minute, a truckload in the first hour. The XPRIZE Wildfire competition is an $11 million global effort to prove that autonomous systems, including AI-enabled drones, ground-based sensor networks, and space-based detection platforms, can collapse that window to 10 minutes. Our guest is Andrea Santy, who leads the program. She came to XPRIZE after nearly two decades at the World Wildlife Fund, where she watched conservation projects fall to wildfire. That experience sharpened her understanding of the stakes: wildfires are now the leading driver of deforestation globally, having surpassed agriculture. In places like the Amazon, the Congo Basin, and parts of tropical East Asia, a single fire can eliminate species found nowhere else on Earth. In cities, it can destroy entire neighborhoods in hours. On January 7, 2025, Santa Ana winds drove flames through Pacific Palisades and Altadena, destroying more than 16,000 structures, killing 30 people, displacing 180,000 residents, and generating between $76 billion and $130 billion in total economic losses from a single event. Annual U.S. wildfire costs, when healthcare, lost productivity, ecosystem damage, and rebuilding are included, are estimated between $394 billion and $893 billion. XPRIZE announced the five autonomous wildfire response finalists just over a year after the LA fires: Anduril, deploying its Lattice AI platform with autonomous fire sentry towers and Ghost X drones; Dryad, running solar-powered mesh sensor networks that detect fires at the smoldering stage; Fire Swarm Solutions, coordinating heavy-lift drone swarms that can deliver 100 gallons of water autonomously; Data Blanket, building rapidly deployable drone swarms for real-time perimeter mapping and suppression; and Wildfire Quest, a team of high school students from Valley Christian High School in San Jose who used multi-sensor triangulation to locate fires that can’t be seen from monitoring positions, solving the literal over-the-hill problem that any fire detection system faces.

The conversation covers what the finalists demonstrated during semi-final trials at 40-mile-per-hour winds, why the decoy fire requirement — distinguishing a wildfire from a barbecue, a pile burn, or a flapping tarp — is one of the hardest AI classification problems in the competition, and how autonomous systems would integrate with existing incident command structures. Santy is direct about where progress is lagging: the testing is ahead of the regulations. Autonomous drones operating beyond visual line of sight and coordinating with manned aircraft in active fire emergencies require FAA frameworks that don’t yet exist at the necessary scale. There’s also the deeper ecological tension — the growing scientific consensus that many fire-adapted landscapes need more fire, not less, and that indigenous fire stewardship practices developed over millennia have a place alongside autonomous suppression technology. One XPRIZE finalist is already working with an indigenous community in Canada to pilot their heavy-lift drone system in a remote area where that community is exploring how the technology fits their land management approach. Meanwhile, the Trump administration’s FY 2026 budget proposes eliminating Forest Service state fire capacity grants, cutting vegetation and watershed management programs by 30%, and zeroing out $300 million in forest research funding — maintaining suppression spending while gutting the prevention and detection infrastructure that could reduce what there is to suppress. The engineering, Santy says, has arrived. Whether the institutions can move at the speed the crisis demands is the harder question.

Interview Transcript
Mitch Ratcliffe 0:09
Hello, good morning, good afternoon, or good evening, wherever you are on this beautiful planet of ours. Welcome to Sustainability In Your Ear. This is the podcast conversation about accelerating the transition to a sustainable, carbon-neutral society, and I’m your host, Mitch Ratcliffe. Thanks for joining the conversation today.
Fire season is coming, and we’re going to dig into how new technology may catch and contain fires in the first few minutes after ignition. There’s a saying among firefighters: you can fight fire in the first second with a spoonful of water, in the first minute with a bucket of water, and in the first hour with a truckload of water. The problem is that by the time most wildfires are detected, minutes have already passed, and in those minutes, under increasingly common conditions, a fire can grow beyond any tanker truck’s capacity.
On January 7, 2025, hurricane-force Santa Ana winds drove flames through Pacific Palisades and Altadena in Los Angeles, and in a matter of hours, more than 16,000 structures were destroyed. Thirty people were killed, and 180,000 residents were forced to flee. The total economic losses are estimated to be between $76 billion and $130 billion from a single fire event. And that was just one week in one city. In 2025, the U.S. recorded more than 61,500 wildfires that burned nearly 5 million acres, leading to annual U.S. wildfire costs of between $394 billion and $893 billion when you factor in the cost of healthcare, lost productivity, ecosystem damage, and the expensive task of rebuilding entire cities.
So there’s an identifiable gap in the current best practices, which take roughly 40 minutes from ignition to deliver a coordinated response. What if you could cut that to 10 minutes, when only a few buckets of water could extinguish a threat? And what if autonomous systems — AI-enabled drones and ground-based sensor networks — could detect a fire, distinguish it from a prescribed burn, and suppress it before getting a human on the radio?
That’s the challenge behind the XPRIZE Wildfire program, an $11 million global competition now entering its final year, and our guest today is Andrea Santy, the program director leading it. Andrea came to XPRIZE after nearly two decades at the World Wildlife Fund, and before that she spent time at the Smithsonian Institution, leading conservation and academic programs.
On January 29 — just after the one-year anniversary of those LA fires — XPRIZE announced the five finalist teams advancing in the autonomous wildfire response track of the competition. They include:
Andruil, a defense technology company deploying a Lattice AI platform with autonomous fire sentry towers and Ghost X drones that watch for fires at the moment they break out;
Dryad, a German company running solar-powered sensor networks that detect fires at the smoldering stage;
Fire Swarm Solutions, a Canadian team coordinating heavy-lift drone swarms that can carry 100 gallons of water autonomously to the point where a fire begins;
Data Blanket, building a rapidly deployable drone swarm system for real-time perimeter mapping and suppression; and
Wildfire Quest, a team of high school students from Valley Christian High School in San Jose who partnered with two aerospace companies to use multi-sensor triangulation to locate fires that cannot be seen from monitoring locations — because, after all, a lot of fires happen just over the hill.
A separate track of the competition, the space-based wildfire detection and intelligence program, includes 10 finalists from six countries who are heading to Australia in April for their own finals. Those teams will have one minute to detect all fires across an area larger than a state, and 10 minutes to deliver precise reports to firefighting decision-makers on the ground.
We’re going to talk with Andrea about what the finalists demonstrated during live trials, why the decoy fire requirement is one of the hardest AI classification problems in the competition, and how these autonomous systems would actually integrate with existing wildfire incident command structures. We’ll also dig into the tension between suppression technology and the growing scientific consensus that many landscapes need more fire, not less, and whether indigenous fire stewardship practices have a place in this conversation.
You can learn more about XPRIZE Wildfire at xprize.org/competitions/wildfire. Can autonomous drones and AI-driven sensor networks actually detect and suppress a wildfire in less than 10 minutes? Let’s find out right after this brief commercial break.
[COMMERCIAL BREAK]
Welcome to the show, Andrea. How are you doing today?
Andrea Santy 5:34
I’m doing great, Mitch. Thanks for having me.
Mitch Ratcliffe 5:34
Well, thanks for joining me. We’ve had XPRIZE leaders on the show a number of times, and you do such interesting work. You announced the finalists just at one year after the catastrophe in LA. How did that reshape the urgency and direction for the XPRIZE Wildfire competition?
Andrea Santy 5:34
It definitely focuses a more intense light on the competition and the need for these solutions. Climate change is driving more intense, more frequent wildfires all around the world, and so I think the urgency was already there. But when you have a disaster at the scale and scope of the LA fires, it absolutely changes the way that everybody thinks about wildfires.
Mitch Ratcliffe 6:04
What’s the realistic timeline for these technologies in the competition to potentially start changing the way that we fight fire and the outcomes of those fires?
Andrea Santy 6:14
So I’ll start by saying we were in LA when the fires started. XPRIZE has a lot of LA-based staff, and we’re originally LA-based, and we were having our staff meeting — so our entire staff was there. We knew from our prize that it was going to be very high risk, and so we were in touch with fire chiefs as the fires were starting. We were able to go out and see where the fires had gone through the Palisades and part of the city — basically 24 hours after it had happened.
It really, I will just say, definitely had a huge impact in terms of being able to see a landscape, communities, homes, schools, and businesses that had been devastated. A lot of the technology being integrated with these solutions can be deployed almost immediately. I think that as the fire agencies begin to get their hands on more of this technology, we’re going to have a hopefully relatively quick uptake. Cameras, sensors, satellite data — a lot of this is already being deployed. So we’re looking at how quickly and under what conditions it can help improve our detection. And then we have other components that I would say are going to have a longer timeline to full deployment.
Mitch Ratcliffe 7:56
It sounds like part of the problem, then, is just knitting all this together. Does that also apply to areas outside of major cities? Do we have the resources to do this on a nationwide basis?
Andrea Santy 8:10
Yeah, absolutely. We’re doing our testing for our space-based competition in Australia, so we’re looking at how you detect fires over vast areas from satellites as quickly as possible and deliver that information down within 10 minutes, with 15-minute updates. For our autonomous track, we’re testing in Alaska — so it will definitely be a real-world scenario where we can understand the capabilities of these technologies in forested areas, in really vast terrain, and under different environmental conditions. Part of why we’re working with these partners is because they’re great partners, but it also allows us to validate this technology under real-world, challenging conditions.
Mitch Ratcliffe 9:03
So how does the wildfire strategy change when this technology is in place? You’ve already mentioned that the climate crisis is accelerating the size and pace of these fires. Is the goal to suppress more fires earlier so that available resources can be deployed to those that actually break out? What’s the big-picture change in policy here?
Andrea Santy 9:26
XPRIZE really decided to double down on early detection and autonomous response, and we have two tracks. I’ll talk about the detection piece first because it’s digestible for everyone. Every wildfire starts small. They don’t start as a huge catastrophe — they start small, often in pretty remote areas. Sometimes they burn really fast, sometimes slower, depending on the conditions. But if you can address a wildfire at its very smallest phase, essentially post-ignition, that gives you the best chance to address it — either through autonomous suppression systems or through your fire service. If you have more eyes, ears, and noses on the landscape, the better your chance of getting that alert as soon as possible, which allows the fire service to decide how to prioritize their resources.
The second component we’re advancing is autonomous detection and response. Sensors and cameras handle the detection; the autonomous response system deploys, verifies there is a fire — that it’s not a barbecue but an actual wildfire that needs suppression — and places suppressant fully autonomously. That’s what we’re going to be testing in Alaska: can they execute this full end-to-end system? Is the technology integrated? Will it reach the scale and scope of the challenge and the geography? Because 1,000 square kilometers — which is our testing area — is roughly the size of San Antonio, Texas. The teams will have to find multiple fires and demonstrate persistent monitoring and persistent response. Imagine having a fire starting in a ravine: if you can get something out there in minutes, your chance of knocking it down — even just deterring the spread enough that firefighters can arrive — we hope will be a game changer.
Mitch Ratcliffe 12:13
We’re talking about autonomous drones. But one of the things that happened in the LA wildfire was that Santa Ana winds were so extreme, fixed-wing aircraft couldn’t fly. Can a drone perform in those conditions?
Andrea Santy 12:27
During our semi-final testing, our team traveled the world to observe these solutions in action. While not at scale, each of the five finalists was able to demonstrate that they could detect a fire, navigate to it, and suppress it fully autonomously over a small area. Coincidentally, relatively strong winds followed us — nothing like the Santa Ana winds, but we had 40-mile-per-hour winds pretty consistently during testing. It was odd, but it was helpful in terms of validating the technology.
Because you don’t have a human pilot, it’s not that helicopters and planes can’t fly — it’s that they can’t fly in that type of wind without putting a human at risk. This approach removes at least that human element. It’s going to continue to be a challenge, but many of the drones have a relatively high wind tolerance, and as the technology improves, the systems themselves are providing the input to stay balanced.
Mitch Ratcliffe 13:54
These systems are also being combined with sensor networks. Can you talk about how those are being deployed?
Andrea Santy 14:01
Some teams are really focused on ultra-early detection by deploying a sensor network — many, many sensors connected through a mesh network — allowing small, distributed sensors across a large area, which gives you great coverage. All of the different teams are competing under the same scenario, so we’ll get to see which technologies work under which conditions. There’s no single silver bullet that works in every condition, every geography, and every forest type. We’re also working on a pilot phase post-competition so the teams can continue to test and deploy, gaining even better understanding. Building trust with fire agencies — so they know what the technology can do under critical situations — is really important.
Mitch Ratcliffe 15:24
Do the fire agencies participate in these trials as well?
Andrea Santy 15:28
Absolutely. We have partners from different fire agencies in Australia — we’re doing our testing with the Rural Fire Service of New South Wales, which is a testing partner. Many of our judges come from different fire agencies across the United States and around the world. From the beginning, that was really an ethos we set forward — making sure this was done hand in hand with the fire agencies.
Mitch Ratcliffe 15:59
You’ve mentioned decoy fires. I’m curious how the trials will incorporate them. You mentioned barbecues — are you going to have people setting up small fires to lure the competition’s sensors?
Andrea Santy 16:11
I can’t say too much because testing hasn’t happened — I can’t give away the secret sauce. But yes — the teams do know they will have decoys and will need to ensure their technology ignores them. It can be anything from something flapping in the wind that resembles the color of fire all the way to barbecues or pile burns — anything that would confuse the technology.
Mitch Ratcliffe 16:52
And that could happen any day of the year. Really interesting. One of the most compelling things about the competition is the breadth of sources of ideas and the range of approaches — including even a high school team from Valley Christian High School in San Jose. What does that diversity tell us about where wildfire innovation will actually come from?
Andrea Santy 17:15
At XPRIZE, we believe that ideas can come from anyone, anywhere, and I think XPRIZE Wildfire really demonstrates what that looks like. We had teams from over 55 different countries enter the competition. We currently have six countries represented through our finals teams, and the range spans from Valley Christian — a high school team — through universities, startups, and all the way up to major industry. That truly spans the whole spectrum.
What I really love about our competition is that for many of the teams, this is both a company and a passion. Wildfires happen in so many places, and so many teams have been personally impacted. The high school team talked about growing up in areas where wildfires are a constant presence — they are very cognizant of the need for these solutions. Something remarkable: one in six Americans live in an area of wildfire risk, and 25% of Californians.
Mitch Ratcliffe 18:57
It’s a very tangible problem for so many of us, particularly in the West. And the smoke from fires in Canada is now familiar on the East Coast — it’s changed the very shape of life. This is a great place to take a quick commercial break. We’ll be right back.
[COMMERCIAL BREAK]
Welcome back to Sustainability In Your Ear. Let’s return to my discussion with Andrea Santy. She is Program Director of XPRIZE Wildfire — a competition headed into its final year with two groups of finalists vying to win shares of an $11 million prize to help commercialize their technologies.
Andrea, the autonomous competition requires teams to detect and suppress a high-risk wildfire in a 1,000-square-kilometer area — roughly the size of San Antonio — and do it within 10 minutes, while ignoring decoy fires. That’s four times faster than current best practices. Have any of the teams met that benchmark yet in the trials?
Andrea Santy 19:57
As I mentioned, the five teams advancing to finals all demonstrated they have end-to-end solutions to autonomously detect, navigate, and suppress a fire. Our semi-final testing was at a much smaller scale, and while some teams did it in less than 10 minutes, this finals competition is at a very large scale — and it is going to be challenging. Every XPRIZE is very audacious. We really want to push the limits, but we’re very confident we’re going to have a team that can do it. Still to be seen, but that is what finals is for.
Mitch Ratcliffe 20:42
Absolutely. It’s great that we’re testing in such diverse settings. Australia and Alaska seem very different. Is that actually the case, or are wildfire conditions globally roughly the same?
Andrea Santy 20:59
Very different. In Alaska, it will be wildfire season, and we’re testing in an area of much lower risk. The vegetation is different. The geography is different. The fuels — the plants and trees — are different. In Australia, the teams will be arriving as it comes out of summer and goes into fall, which means we don’t actually know exactly which specific days we’ll test, because the Rural Fire Service has to execute prescribed burns when it’s safe. We have a two-week testing window, with five planned days of testing, and approximately 20 fires of varying sizes that the teams will need to identify under different conditions and vegetation types.
Mitch Ratcliffe 22:11
Let’s talk a bit about the space-based prize. Lockheed Martin is adding a million dollars for the teams that can demonstrate the fastest and most accurate detection. Is detection turning out to be the harder technical problem — or is it the transition from detection to action, that coordination piece we talked about?
Andrea Santy 22:40
Lockheed Martin is supporting the autonomous wildfire response track — which we call Track B. The autonomous track requires teams to detect, navigate, and suppress, with all teams using drones. There’s a lot of different detection technology, from sensors that detect particulates up to cameras, and sensors and cameras mounted on drones.
Getting that detection into these autonomous response systems is really the step change — having something that communicates without human intervention, with drones that can fly under wind conditions and navigate to the right location, confirm there’s a fire, and then suppress it accurately. The teams will be testing on a moving fire — not a barrel of fire, but an actual fire that will be dynamic and small-scale but moving. That’s really challenging and requires quite a bit of system training. During semi-finals, accurately hitting the target was one of the harder challenges.
Mitch Ratcliffe 24:43
As you talk about it, it sounds like the transition from detection to addressing the fire appropriately — choosing the right suppression mechanism — is something you’ll continue to work on.
Andrea Santy 24:58
The teams are definitely still working on their systems. They have until June to have all of their systems working. Yeah, it requires a lot of different components.
Mitch Ratcliffe 25:20
And obviously that’s part of the bigger challenge — coordinating technological responses to a changing climate and acute situations like fire. As you observe the environment with these systems, are we also potentially identifying opportunities for prescribed burns in order to reduce fire risk?
Andrea Santy 25:45
Absolutely. While our competition is focused on detection and response to incipient-stage wildfires, I do think this technology can be utilized across many different scenarios — including prescribed burns, where you want to monitor large burn areas to ensure nothing escapes. That is definitely a use case, and anything that reduces our risk. Personally, I think it could provide peace of mind: if you have something on hand that can prevent a prescribed fire from spreading when weather conditions change unexpectedly, that’s enormously valuable.
Mitch Ratcliffe 26:43
Indigenous communities have managed fire for millennia using these kinds of burning practices. Have you engaged with tribal fire practitioners? Do they see autonomous technology as complementary to, or in tension with, their traditional fire stewardship programs?
Andrea Santy 27:02
We have engaged with some. I was just at a meeting where I was able to meet with a representative from an indigenous community in Canada, and they are actually going to pilot-test one of the team’s technologies — specifically a team with a heavy-lift drone. It was really exciting to talk with them and learn more about how they envision it being used. Their community is quite remote, and understanding how this technology could work within their context was a great conversation.
Mitch Ratcliffe 27:41
When I think about the swarm of drones approach to fire management, the regulatory landscape seems like a significant challenge. The FAA has been grappling with drone airspace management. Does the regulatory framework need to change significantly to accommodate these systems?
Andrea Santy 28:06
That’s an excellent question. Current regulations and protocol don’t allow drones in airspace with manned aircraft. As the technology gets better, there are definitely ways this can happen — there are pilots and tests already occurring with other partners looking at shared airspace for heavy-lift drones operating at higher altitudes. Beyond visual line of sight is one area where the testing is definitely ahead of where the regulations are.
Mitch Ratcliffe 28:55
What has your conservation career taught you about how technology deployment can shape our relationship with nature?
Andrea Santy 29:07
I got into this position in part because many of the projects I was working on at the World Wildlife Fund were being lost to wildfire, and I felt we hadn’t really understood the impact of wildfires on conservation. Wildfires are now the main driver of deforestation globally, having surpassed agriculture. In places like the Amazon, the Congo, and parts of tropical East Asia, there’s such critical biodiversity — and I think if we can use technology to monitor these areas, understand where fires are happening, and deploy appropriate responses, my hope is that we can save really, really important places. There are endemic species that only live in very, very small areas, and one fire could wipe out an entire species.
I also worked for a long time on projects where your goal was 20 to 50 years away. Being able to work with XPRIZE, where in three years we’ve seen an absolute transformation in both what the technology can do and how people understand what technology is for — I think we need more of these competitions, more technology applied to conservation problems. I’m really hopeful.
Mitch Ratcliffe 31:23
After three years with XPRIZE Wildfire, do you feel like we can turn back the rising incidence of wildfire and all the costs we’re seeing pile up when cities burn?
Andrea Santy 31:35
I think so. Communities and citizens around the world are understanding the problem at a deeper level. This is going to be all hands on deck. You need citizens and homeowners making sure they have zone zero — no vegetation around their homes. You need communities, city and state incentives, industry engagement. You need prescribed fire and better forest management policies that allow good fire on the landscape, and communities that encourage it. All of these factors together are what will get us to a new paradigm.
Mitch Ratcliffe 32:29
You mentioned raising awareness — this competition actually sounds like really good TV. Have you thought about how to tell this story of wildfire innovation so that people can get engaged with and behind this kind of activity?
Andrea Santy 32:49
We’ve discussed at length how we would be able to document some of the testing. For the autonomous wildfire response, it is a very big, vast area, and turning it into good TV is probably a step beyond us — but I think the teams have amazing stories to tell. We’re going to capture a lot of imagery to share that story out. We have a resource page that provides a lot of different information to homeowners and individuals about other really amazing organizations doing great work in the wildfire space.
Mitch Ratcliffe 33:47
How can our listeners follow along as you complete the project?
Andrea Santy 33:51
We’d love to have them follow along. The easiest way is xprize.org/wildfire — we have lots of information about the competition and the teams, lookbooks to learn about which teams are competing, social media updates, and a newsletter you can subscribe to. During the testing events we’ll be sharing quite a bit of good information. The events are in fairly remote, closed-system locations, so we can’t invite everyone there — but we’ll definitely be exploring how to make sure as many people as possible can get their eyes on what we’re doing.
Mitch Ratcliffe 34:42
Andrea, thank you very much for spending time with us today. It’s been a really interesting conversation.
Andrea Santy 34:48
Thank you so much. We hope all your listeners think deeply about wildfire and what they can do. Our goal is that collectively we can all work together to reduce this wildfire risk and keep good fire on the landscape.
[COMMERCIAL BREAK]
Mitch Ratcliffe 35:11
Welcome back to Sustainability In Your Ear. You’ve been listening to my conversation with Andrea Santy, Program Director of XPRIZE Wildfire, an $11 million global competition now in its final year. Learn more and follow the finalists at xprize.org/competitions/wildfire.
This conversation revealed, at least for me, that solutions to wildfire are arriving — but perhaps faster than the systems built to receive them can accept and use them. We’ll need more public funding to deploy these technologies, and right now we’re moving in the wrong direction. As wildfire damage grows, total federal wildfire spending is holding roughly flat at around $7 billion a year. However, the Trump administration’s FY 2026 budget proposes eliminating the Forest Service’s state fire capacity grants, cutting vegetation and watershed management programs by 30%, and zeroing out the $300 million in forest research funding that was in the budget previously. So we’re maintaining the suppression budget while cutting the prevention, detection, and research infrastructure that could reduce what we have to suppress.
Fortunately, we have XPRIZE Wildfire to take on some of the burden — but it’s not enough. Consider what Andrea said about early detection: every wildfire does start small. If autonomous systems can get suppressant on a fire quickly enough, it might not even need to be fully extinguished — just deterred enough that firefighters can arrive to finish the job. The technology to do that end-to-end and autonomously is already being demonstrated in the field. But Andrea was equally direct about what’s lagging: the testing is ahead of where the regulations are.
Consider autonomous drones operating beyond visual line of sight and coordinating with manned aircraft during active fire emergencies. For that to work, the FAA’s frameworks for widespread drone operations need to be reinvented. The recent closure of El Paso International Airport over nearby counter-drone laser testing is evidence of how unprepared we truly are for the innovations that are coming.
In short, the engineering has arrived, but institutions need support to integrate that engineering into their operations. A similar gap is evident in who’s doing the innovating: teams from over 55 countries entered this competition, and a high school team from San Jose made the finals by solving the problem of locating fires beyond ridgelines using multi-sensor triangulation — not because they had institutional backing, but because they had access to a well-defined problem and the drive to solve it, along with the incentive of XPRIZE’s $11 million award.
The XPRIZE premise that ideas can come from anyone, anywhere — it turns out — is literally true. But recognizing that changes nothing if the regulatory, procurement, and deployment systems still favor incumbents and slow-moving approval processes.
Underlying all these challenges is what Andrea brought to this work from nearly two decades at the World Wildlife Fund: wildfires are now the leading driver of deforestation globally, having surpassed agriculture. The game has changed, but policy is still anchored in now-outdated 20th-century strategies. One fire in the wrong place can drive a species to extinction, or it can burn a city to the ground.
Andrea said she’s hopeful — not because the problem is easy, but because in three years she’s watched a transformation in what technology can do and how people understand what technology is for. That hope is well earned. But it will only translate into outcomes if institutions move at the speed the crisis demands — citizens, homeowners, communities, industries, and policy, all moving together. The competition creates urgency; the systems around it need to act on and use the innovations being delivered.
