The 4 Truths of PLA Straws
This article was written by Kevin Majoros
Plastic pollution is one of the biggest environmental challenges of our time, with statistics showing there will be more plastic in the ocean than there are fish, by volume, by 2050. Restaurants, venues and establishments worldwide are working to combat plastic pollution by eliminating plastic straws.
Recently, notable hospitality, restaurant and airline brands have eliminated single-use plastic straws, while cities like Seattle, San Francisco, Washington, D.C. and more have banned plastic straws entirely. Whether it be part of legislation or conservation efforts, many brands are switching from plastic to a sustainable alternative, often PLA, without knowing the real truth about the dangers of a PLA straw.

Consumers, restaurants and businesses believe they are making an environmentally sound choice by using or offering PLA straws over single-use plastic straws. But, that’s not always the case.
PLA “biodegradable” straws are positioned as straws made from plants that can break down in the environment. They are made from naturally occurring, plant material such as renewable resources like cornstarch or sugar cane. While PLA plastic is typically a better alternative than its close relative, the traditional petroleum-based plastic, they aren’t the most environmentally sound option.
Because many consumers and businesses are not aware of the real facts about PLA straws, outlined are four truths about PLA straws to consider before you decide to make the switch.
Truth #1: PLA straws require specific disposal conditions.
PLA straws require industrial composting conditions, meaning consumers or businesses must have access to a commercial compost facility, which are only available in certain parts of the U.S.
In order for PLA straws to compost, they require temperatures above 140 degrees Fahrenheit for 10 consecutive days and need to be properly routed to specialized industrial composting or recycling facilities to break down. While this is possible in a composting facility, few facilities exist to break down PLA straws.
Truth #2: PLA straws can act the same as traditional plastic straws.
Many studies show that PLA straws are almost impossible to decompose in a landfill and cannot be composted at home or through backyard systems. Disposing any type of PLA, bioplastic or “plant-based” plastic straw is no different than throwing away a regular plastic straw.
Not only are PLA straws impossible to decompose in a landfill, like traditional plastic straws, they are especially dangerous if they end up in our waterways and ocean. Since they do not break down here, PLA straws are just as likely to be consumed by marine wildlife and fish, ultimately endangering or killing them.
Truth #3: Consumers don’t know the difference.
The issue with PLA straws is that people think they are using an environmentally-friendly product, which is true, if disposed of correctly. The reality is that they are not. People don’t know where to dispose of it and question whether it goes in a general recycling bin, the trash or a plastics recycling bin. The answer? None of the above.

Although PLA is compostable, PLA straws must be sorted and put into its own industrial composting collection bin – an option rarely found in the U.S.
An article from Smithsonian magazine explains, “Recycling facilities have problems with PLA too. They worry that consumers will simply dump PLA in with their PET … PLA and PET mix about as well as oil and water, recyclers consider PLA a contaminant. They have to pay to sort it out and pay again to dispose of it.”
The confusion surrounding PLA disposal becomes an even bigger issue when it is used outside of individual households and in foodservice settings.
Truth #4: PLA straws are cumbersome to operators.
While PLA straws are “compostable,” it cannot be mixed with other types of plastics because PLA has a lower melting temperature that causes problems at recycling centers. This means it cannot be recycled with other curbside recycling.
Restaurants and businesses using PLA straws must sort their PLA products separately from other recyclables to have them commercially composted. They must also arrange a pickup or drop off at a commercial composter and pay to recycle PLA straws.
On top of having to clean and turn tables quickly, this means that restaurant operators must further separate tabletop garbage and recyclable items.
More education is needed to understand the process behind disposing of PLA, and there is a huge gap within the community as consumers believe using a PLA straw is an eco-friendly option to the plastic straw. We all have a social responsibility to teach businesses, consumers, family and friends the truth of PLA straws and what other sustainable options are available to us.

Your options for a greener planet
If you want to do Planet Earth a favor, the most sustainable choice is to not use a straw at all. Of course, many people need or want a straw to sip their beverage, and in that case, the most environmentally friendly options are reusable straws such as glass or stainless steel. These might be an option for personal use, but it is not for foodservice operations due to sanitation and safety concerns.
Other alternatives cause problems as well, like the wheat straw, avocado pit straw and noodle straw, as these straws have the possibility to cause allergic reactions and may have an unfavorable taste and texture.
Paper straws remain the best option for foodservice and venues because they are an environmentally safe, single-use option, but as we all know, not all paper straws are made equally.
As the paper straw movement grows, so does the number of paper straw options at our fingertips. Some paper straws are 100% compostable and made with FDA-approved adhesive, inks and papers and last multiple hours in liquid. Others give paper straws a bad reputation when they’re made with toxic dyes and break down in minutes.
The next time you are looking for a sustainable straw option, do some research and look for paper straws that are not only durable but use paper that was responsibly harvested.

Sixteen days in Tunisia

Tunisia is named after Tunis. Not the other way around. If the country takes its name from the city, then any attempt to understand Tunisia must start in Tunis.
Before reading any further, look at a map. You must appreciate the exceptional location of Tunis; only then does the city make full sense. Historically, Tunis was little more than a compact nucleus pressed in the strip of land between the Séjoumi lagoon (a flamingo sanctuary) and Lake Tunis, once the natural harbour. Everything that now feels expansive, avenues, neighbourhoods, infrastructure, rests on land reclaimed from water. Bab Al-Bhar, the Sea Gate, crystallises this transformation: standing there today, flanked by white buildings, you have to imagine the water once visible straight through the gate. The city quite literally stole land from the sea as it expanded.
That tension between land and water, between natural geography and human intervention, repeats itself everywhere in Tunisia. An artificial peninsula appears in the ancient harbours of Carthage. Salt lakes replace vanished seas in Chott el Djerid. Urban coastlines are pushed back, fortified, paved over. Today, the landscape bears the marks of centuries of negotiation with water, sometimes reverent, sometimes violent. But let’s stay in the capital for a moment.
Visiting the medina (old town) on a Sunday, when most souks are closed, made the architecture audible. Without the commercial noise, proportions, light and texture take over; the business-day buzz is thrilling, but silence teaches you how the city breathes. That quiet also sharpens your attention to thresholds. And then the beauty of the doors hits you. Again and again. Painted, carved, symbolic, they demand to be read, often concealing unexpected worlds behind them. In the medina, access is never guaranteed: museums may still be family homes, so you knock, you wait and someone might let you in. Knowledge survives through generosity. This constant negotiation between private and public space explains why repurposing feels so natural here. People inhabit ancient burial sites, former shrines become cafés and even the old slave market has transformed into the jewellers’ quarter; history reused rather than erased. The twenty madrasas scattered through the medina embody this logic perfectly: still embedded in daily life, neither fully public nor entirely private, their doors test your luck. Finally stepping inside one felt unreal, courtyards opening suddenly, tiled interiors that seemed imagined rather than constructed. I honestly felt I was dreaming.
But don’t forget to look up, as architecture constantly communicates power, belief and belonging, often far more than we initially perceive. The green-tiled domes signalling burial places, the octagonal or patterned motifs minarets proclaiming variants of Islam (Ottoman and Almohad respectively) or the colour codes identifying hammams and barber shops all speak a visual language that locals instinctively read. In Tunis, belief is never private, it is inscribed into skylines and façades.
That inscription extends inward. Mosques feel less like austere institutions than wellness centres, spaces of rest, learning and calm. Mats are placed against ancient columns to shield people’s backs from the cool marble. I even witnessed people nap inside Al-Zaytuna. So much peace that you can sleep. How do churches compare?

Al-Zaytuna itself is the city’s anchor, the Great Mosque. The souks grew around it, originally as little more than rented awnings, now covered streets wrapping commerce around devotion. You walk through trade and suddenly stumble into the sacred. Built in the seventh century, shortly after the Islamic conquest of Byzantine Africa, the mosque stands on layers of belief. While it is likely that a temple existed here since antiquity, legend says it was built on the shrine of Saint Olive of Palermo. “Zaytuna” means olive, in Arabic and in Spanish. Language preserves memory even when stones are repurposed. Indeed, the entire prayer hall is held by a forest of Roman columns and capitals, older worlds literally supporting newer ones.
As a Spaniard, Tunisia had many a surprise in store for me. Rue des Andalous reveals one of Tunisia’s most consequential migrations. During the Middle Ages, much of Spain was Muslim. Forced conversions, expulsions and finally the mass expulsion even of Moriscos (former Muslims converted to Christianity) in 1609 drove tens of thousands across the sea. Spain was Al-Andalus in Arabic and so these Spaniards became known as “Andalusians”. Large numbers settled in Tunisia, founding neighbourhoods and entire industries. That legacy is not abstract. Chechias, the characteristic red felt hats associated with Tunisois men, were produced using techniques brought by Andalusian refugees. By the nineteenth century, chechia makers were among the wealthiest and most influential merchants in Tunis. The Tunis souks where you can still watch them work are living archives of forced migration turned cultural inheritance. Indeed, the link with Al-Andalus is still emotionally present. Several people called me “cousin” when I told them I was Spanish. It did not feel metaphorical. It felt familial. Spanish presence resurfaces repeatedly: forts at La Goulette, inscriptions in Castilian, Andalusian refugees founding towns like Testour, where the mosque clock runs backwards (‘anticlockwise’) like Arabic script. Jewish and Muslim Spaniards built whole towns together after fleeing persecution. They brought urban planning, architecture, food and memory.

Non-human animals are also everywhere if you know where to look, silently narrating human history. Today, cats dominate Tunis, lounging, glamorous, fully at home in the city. But North Africa was once also home to another feline: lions, ultimately erased from the landscape by hunting. At the Bardo museum, Roman mosaics celebrate them while also depicting their mass slaughter in amphitheatres. Venationes (gladiatorial hunting shows) paved the way to extinction long before modern poaching. Rome’s “games” were ecological disasters disguised as entertainment. El Djem boasts the third largest amphitheatre in the world, an uncomfortable reminder that the spectacle of violence against animals became industrial. Birds, too, mark survival. Storks now nest on electrical poles, thanks to recent conservationist efforts, and the ancient castle on the artificial Chikly island in Lake Tunis is now a natural reserve for over fifty-seven species.
Water management reveals another continuity of power. Ancient Carthage was defined by water engineering. Artificial harbours, commercial and naval, remain legible after 2,200 years. Aqueducts carried water across vast distances; cisterns stored enough to sustain one of the Mediterranean’s largest cities. Fresh water was sacred. Springs, such as that at Zaghouan, were divine. Nymphs were believed to guard the source so temples rose where water emerged from the rock. But human transformations of the landscape sometimes rival natural phenomena. Chott el Djerid, now a salt desert, was once part of the Mediterranean Sea. When geological shifts cut it off, the water evaporated, leaving salt behind. The salt is now actively extracted and shipped north, sold to Scandinavian countries as grit to combat icy roads. At the same time, visions of reversing this desiccation persist, from colonial-era schemes to the revival of the “Sahara Sea” project in the 2010s, approved by the Tunisian state in 2018. Coastlines have also been shaped by humans. Hammamet’s medina once met the waves directly. Boulders and walkways intervened. Monastir’s ribat once stood on the beach before roads severed it from the sea. Sousse’s medina now violently cut away from the Mediterranean. Tunisia has never stopped imagining how to reshape water.



Just as water and animals shape human settlement, so too does climate. Again and again in Tunisia, habitation reveals extraordinary adaptation to environment. At the ancient site of Bulla Regia, houses were built partly underground to escape heat, flooding interior spaces with light while sheltering them from extremes. At Matmata, troglodyte dwellings carved into the earth have stabilised temperature in a harsh desert landscape for centuries. At Zriba Olia, a town only abandoned decades ago, Amazigh (Berber) architecture merges seamlessly with mountain rock: the house ends, the mountain begins. Even the Roman theatre at Dougga takes perfect advantage of the mountain’s elevation. These are not picturesque oddities; they are intelligent, time-tested responses to landscape. But changes aren’t always benign, especially when colonial brutality is concerned. In Carthage, Roman policy deliberately buried, erased and levelled the Punic past on Byrsa Hill. Centuries later, French authorities turned amphitheatres into chapels, erected cathedrals atop Punic acropolises and even built a farmhouse on the Roman capitol at Oudna. Layers of civilisation were literally crushed to assert dominance. The irony is that archaeology eventually resurrected what imperial ideology tried to annihilate.



Language binds all of this astonishing diversity together. Phoenician (Punic) script underpins our Latin alphabet. Tifinagh survives among Amazigh communities. Writing systems are fossils of contact. Even humour reveals linguistic layering: Tunisians seem to have the worst, and best, wordplay, producing gems like “Pub-elle”, “Bar Celone” or “Mec Anic”, jokes cleverly built on French that land perfectly in Tunisian streets. Religion, too, refuses neat boundaries. Phoenician deities merge with Egyptian, Persian and Roman gods. Judaism flourished in North Africa from antiquity and remained deeply rooted in Tunisia until the twentieth century. Christianity arrived early, fractured into multiple denominations and left basilicas, cathedrals and martyrs’ narratives across the landscape. Islam absorbed, adapted and reinterpreted what came before. Syncretism is not the exception here, it is the rule.
By the end, what remains clearest is this: Tunisia is not a palimpsest with erased layers. It is an accumulation where nothing disappears entirely. Former seas leave salt. Empires leave infrastructure. Migrations leave words, recipes, and cousins!
Sixteen days is nothing.
And it was everything.

Running Wild: The Return of Patagonia National Park’s Rheas
The Chacabuco Valley stretched wide before us. The golden steppe was broken by winding rivers, framed by snow-capped ridges that seemed to glow in the fall sun. We were in the heart of Patagonia National Park, a place reborn from what used to be one of the largest sheep ranches in Chile. Old Estancias once carved the land into squares made of barbed wire and filled with overgrazed pastures. But today, those fences are gone. The grasslands pulse with guanacos again and the park has become a symbol of what rewilding can mean when it’s done right.
We’d come here to see a beacon of rewilding in the area, which took shape as an oddly familiar looking species of bird called the Darwin’s rhea (known locally as ñandú or choique.) It’s Patagonia’s strangest survivors, this flightless animal with legs built for speed and feathers streaked in soft browns that disappear into the grass. From a distance, they look almost prehistoric, like something you might imagine darting across the steppe in a bygone epoch. Up close, they’re ecosystem engineers, spreading seeds that shape grassland health, and feed predators such as pumas and foxes that depend on them for survival.

These birds possess an unusual way of fertilizing the land, making them critical players and worth a heavy invesment in their rewilding. Unlike guanacos, which use fixed latrines (skat dropping areas) that concentrate nutrients in one spot, rheas are wanderers in every sense. As they roam, they drop seeds across the steppe in a steady scatter, with each pile of droppings carried further by rodents like tuco-tucos that burrow and churn the soil. This gives plants a chance to take root in Patagonia’s harsh winds. It’s a less prominent, yet highly fundamental cycle where rheas eat, move, fertilize, and in doing so, stitch the landscape together. Without them, the steppe would grow weaker and far less resilient.

Rheas, standing about three feet tall, are designed to vanish into Patagonia’s grasslands rather than dominate them. Rheas move almost like ghosts, disappearing into the landscape until you realize the ground itself was alive and moving all along. And yet here, in what should be one of their strongholds, rheas had nearly vanished.
Just a decade ago, a survey inside the park found fewer than 22 individuals left—a catastrophically low number for a bird so integral. The reasons were painfully manmade, as they often are when it comes to biodiversity loss like this. Decades of ranching, which ended here in 2008, had blanketed the valley in fences that trapped and killed rheas. Eggs were taken for food, chicks were chased down, and their range shrank until they were pushing just shy of a memory.

That’s where Emiliana Retamal, a young veterinarian turned wildlife ranger, comes into the conversation. She’s part of a small team with Rewilding Chile trying to bring rheas back to the Chacabuco steppe. The first thing she said upon meeting was to slow our movements, talk less, and to follow her lead when approaching these flightless wonders. We were off to the holding pens that served as a temporary home for both rhea adults and chicks, known here as charitos. Some of them were getting ready to be released into the wild, marking another historic moment for the rewilding team.
The following morning was all about getting things right. Rewilding Chile’s rhea initiative, called Ñandú Conservation and Recovery Programme, has been running since 2014. Ever since, the team has been incubating eggs, raising chicks, slowly reintroducing birds into the wild, all building toward a goal of restoring a self-sustaining population of at least 100 adults and at least four actively reproducing.

For Emiliana, release days are equal parts research, nerves, and a ton of hope. Each bird is carefully prepared, including mandatory health checks, parasite treatments, and a period of acclimatization inside open-air pens where they gain strength and learn to fend for themselves. The idea is not to domesticate them in any way, but rather, give them just enough of a head start to survive top predators, and Patagonia’s harsh winters once the pen gates swing open. Some are fitted with GPS collars—the first of their kind for monitoring rheas here—allowing the team to track their survival rates and see if they’re reproducing in the wild.
We were fortunate enough to witness this particular relase, which was a true milestone. Alongside captive-born birds, a group of 15 rheas had been translocated from Argentina for the first time. These wild individuals were specifically brought in to bolster genetics. These bird groups act quite differently, with the wild ones moving as a tighter group and demonstrating discomfort around people. That’s exactly what Emiliana wants, as the goal is to ensure the animals remember what it means to be wild or remain entirely wild to up their chances of survival.

When the moment finally came, the puesto (or field station) buzzed with controlled urgency. Emiliana and her patchwork team of rangers, vets, community leaders, and allies, moved with practiced rhythm, coaxing these powerful, awkward-looking birds into small wooden crates. These rheas were not tame, so asking them to willingly go into confinement requires a patient and steady hand. Every movement was about safety—maximizing calmness while minimizing stress, and avoiding injury for all.
Outside, a convoy of trucks rumbled to life while drones circled high above, ready to follow the release. Autumn had painted the surrounding forests in fire-reds, yellows and oranges. The air carried the kind of crispness that warned of winter’s approach. Bundled in layers, we set off across the park along a road that wound through valleys where iconic mountains dominated the horizon. The landscape begged us to stop and stare, but the mission pushed us forward. When we reached the release site, the cages were lifted down and arranged side by side. The team stood in a nervous silence. Everything was ready, so the countdown began.

On the count of three, the gates opened and the wranglers stepped back fast. For a heartbeat, not a single bird moved. Then, with a rush of feathers and legs, the rheas spilled out into the open, scattering across the grasslands like wind made visible. Some lingered, hesitating at the threshold. Others bolted in tight groups, vanishing into the tawny steppe. It certainly was not graceful, but it was emotional nonetheless. A species that had nearly disappeared from this place was running free, once again.
Releases like this may look simple. Open the gates, let the birds run, right? But the reality is far from it. Rewilding is hard work, and with rheas, it’s closer to brutal. In the wild, more than half of chicks don’t survive their first year. Eggs are eaten by predators or trampled by livestock, chicks are picked off by foxes, eagles, and pumas, and even curiosity can be fatal. Young birds often die from mistaking the wrong thing for food, like rocks or other inedible objects. And on top of that, the male birds are sometimes left caring for 50 chicks at once, making survival that much harder. Add to that the genetic bottleneck of starting with so few individuals in the wild, and every single bird that makes it into adulthood feels like a victory against impossible odds.

That’s why Emiliana and her team treat each rhea like an individual case study. Every release is followed by weeks of long days in the field monitoring and collecting data. Collars on individuals provide glimpses of survival, but much of the knowledge still comes from old-fashioned ranger work of tracking footprints across the steppe. Their job next will be to spot birds from a distance, asking local police and community members to report sightings to speed up the process.
And yet, for all the setbacks, the progress is undeniable for this team. From a ghost population of just 22 individuals to more than 70 now roaming the Chacabuco steppe, the recovery is indisputable. But numbers alone aren’t enough around here. Survival depends on genetics, and until recently, most of the birds released here had been hatched or raised in captivity. This means they were strong in body, but softer in instinct. This release however, was marking a turning point.

These 15 wild rheas translocated from Argentina to Puesto Ñandú—just a few kilometers from the border—arrived carrying what captive-bred birds could not: diverse DNA, sharper instincts, and that memory of how to live without the aid of humans. While borders divide people, they mean nothing to the animals who cross them freely. Rheas don’t recognize Chile or Argentina, but they recognize habitat. And if this recovery is to last, it will take both nations working together to protect the grasslands they share.
Even with the numbers trending upward, one of the biggest challenges is, of course, social. In nearby Cochrane, Emiliana is known casually as “the choique girl.” People are aware of the project, but they don’t always feel ownership of it. Many still see the park as something created by outsiders, disconnected from their lives. That gap is fundamental, and something the Rewilding Chile team, as well as its other collaborators including Quimán Reserve, CONAF (Chile’s National Forestry Corporation), SAG (Agriculture and Livestock Service) and Carabineros de Chile, are putting emphasis on. Rewilding efforts must be equally about saving species and building genuine relationships with communities or everything done in the field will not be effective.

Being in attendance on that release day, standing in the steppe as the cages opened and rheas burst back into a landscape that once nearly lost them, was something that will never escape our memory. The pride on the team’s faces, the outward relief after months of preparation, the sight of those birds vanishing into the golden grasslands, all felt triumphant.
As Emiliana reminded us, this is only the beginning. In the vastness of Patagonia National Park, surrounded by snow-capped ridges and rivers that once ran through sheep pastures, the work ahead is as immense as the landscape itself. Watching rheas roam free again was proof that rewilding means to restore the past, in addition to defining a new future, where ecosystems can someday thrive without our intervention.

What Next Generation Leaders Can Learn From The Tompkins’ Legacy
When I think about some of the most impactful conservation wins of our time, the global ivory bans, the U.S. Marine Mammal Protection Act, or Canada’s phaseout of open-net salmon farms immediately surfaces. But there’s one that seems to present front-and-center for me, especially since I identify as both a capitalist and a conservationist, as being particularly timely. The large-scale rewilding efforts across Chile and Argentina stand out as compelling case studies of what’s possible when bold vision, private capital, and ecological urgency collide. For anyone in business today, it challenges us to rethink what meaningful contribution looks like in a world that can no longer afford business as usual.
The pair behind this effort are Kris Tompkins and the late Doug Tompkins. Doug co-founded The North Face and later Esprit, two powerhouse brands that redefined outdoor and fashion industries. Kris was Patagonia’s inaugural CEO, shaping it into a globally recognized ethical apparel company. Together, they drew a direct line between wealth and responsibility to establish Tompkins Conservation. The organization’s objective was to place focus on and highlight geographical regions or areas that they held personal ties to. Doug stated he would use his fortune to “pay rent to planet Earth.”

Over two decades, Doug and Kris donated more than 3 million acres in Chile and Argentina, creating over a dozen national parks. Before his untimely death exactly 10 years ago from a kayaking accident, Doug’s final vision was the Route of Parks of Patagonia—a 2,800-kilometer corridor linking 17 parks and 60 communities across Chile. It was a radical undertaking aiming to restore entire ecosystems that reconnected wildlife, all while creating livelihoods that didn’t rely on extractive industries like mining or industrial fishing.
Born from Tompkins Conservation, both Rewilding Chile and Rewilding Argentina were created to carry out Doug and Kris’s mission, but more so to ensure these efforts evolved beyond the individuals themselves. They made a deliberate choice to hand the work to local leaders who understand these ecosystems as home. Today, those leaders and their counterparts are both honoring Doug’s legacy and expanding Kris’s vision in ways only they can. That has even meant taking their work beyond the two country borders.

This year at Climate Week in New York, Kris inspired the launch of the Jaguar River Initiative, which is a continental-scale rewilding effort stretching across Argentina, Bolivia, Brazil, and Paraguay. It’s one of the most ambitious ecological restoration projects in the Global South, led by on-ground conservationists who understand these landscapes as more than boundaries, but as a single, continuous living system.
Directed by Deli Saavedra, the vision is to rewild the river corridors that function as the connective tissue of a million square mile ecosystem. In doing so, this will restore the movement of jaguars, giant river otters, anteaters, and other keystone species, while addressing the cascading pressures of climate change and habitat loss. Drought, wildfires, industrial encroachment, agriculture, and deforestation have fragmented this region for decades. However, the success of Argentina’s Iberá Wetlands—where jaguars have returned after more than 70 years and local communities built an economy around restoration—proved that recovery at scale is not only possible, but replicable.

The concept is to take what worked in Iberá and apply the concept elsewhere. It’s the essence of “positive deviance,” or identifying what’s working against the odds, understanding why, and helping others replicate and adapt it in their own contexts. This initiative is the genesis of my work with Edges of Earth, where we seek out ready-made solutions already succeeding locally, and help these organizational stories reach the world so there’s opportunities to scale both locally and globally.
Over nearly eight weeks, Adam Moore—our expedition operations lead—and I, immersed into the worlds of Rewilding Chile and Rewilding Argentina to see their impact firsthand. In Patagonia National Park, we saw why rewilding matters. As we crossed sweeping valleys filled with guanaco herds and climbed ridgelines where Darwin’s rhea now roam after teetering on the edge of extinction, the vision that Doug and Kris championed felt like a promise made, and kept, to Chile.
The park’s rewilding story continues: Running Wild: The Return of Patagonia National Park’s Rheas

A place Doug loved so deeply it now carries his name, Pumalín Douglas Tompkins National Park, showed us a completely different face of Patagonia. At Caleta Gonzalo Lodge, designed by Doug and Kris themselves, the scenery shifts from the iconic windblown steppe to a world of fjords, waterfalls, glaciers, ancient alerce trees, and volcanoes that rival the Pacific Ring of Fire. This was Doug’s living laboratory, where he tested the radical idea that conservation could be run with the same rigor and ambition as a business empire. By 2018, that experiment became history. When 1,063,000 acres were protected in the largest private land donation ever made to any government, Kris proved that when vision meets capital, an entire nation’s map can be redrawn.

On the other side, Rewilding Argentina has created and/or expanded 10 national and provincial parks through the donation of 464,098 hectares of land. Altogether, their work now protects an extraordinary 1,611,413 hectares—an area so vast it’s almost hard to comprehend. And at the heart of it sits the Iberá Wetlands, one of the world’s largest freshwater ecosystems. Argentina’s most powerful rewilding success story.
Traveling with Marisi López, who has been part of this movement since the earliest days, we learned just how improbable this transformation once seemed. Iberá was not always a wildlife stronghold. For decades, much of the region was hunted out, fragmented by agriculture, heavily deforested for industrial purposes, and degraded by invasive species. The land once felt empty, without critical keystone species keeping the balance in check. Today, we moved through landscapes that had once been silent, only to be met with an explosion of life featuring jaguars relaxing in dense underbrush; giant river otters carving patterns through the water and; capibaras rolling around on the dirt road blocking our car from moving much more than an inch at times.

Yes, the return of wildlife makes this story impressive. But perhaps even more critical has been the return of identity. Communities that once relied on extractive industries or had no work opportunity at all, now have alternate livelihoods. The success of Iberá is what sparked a continental ripple after decades of working towards it. Today, it serves as the blueprint for rewilding across the Americas, and perhaps beyond.
It’s important to recognize that the Tompkins legacy has inspired a new generation of conservationists to launch their own initiatives and chart their own paths. Edges of Earth partnered with Por el Mar, a grassroots marine conservation group working to protect the region’s cold-water ecosystems, especially its pristine giant kelp forests.

For three weeks, we traveled with their team from Tierra del Fuego to Santa Cruz, living aboard a small sailing vessel and diving into some of the last intact underwater forests like this on the planet. These ecosystems, towering and ancient, are now threatened by warming seas, industrial fishing, and invasive species all over the world. But here, this team has been instrumental in protecting giant kelp up and down the coast, mitigating the crisis the best they can before it’s too late.
Co-Founder & CEO Martina Sasso, along with some of her founding team, emerged from the Rewilding Argentina network. People once touched by the Tompkins philosophy but determined to create their own impact. Their work blends science and community outreach, building stewardship for ecosystems that have long been overlooked. In many ways, Por el Mar represents the natural evolution of the Tompkins vision, by helping those who have turned their back on natural resources to see their value once again.

I also must acknowledge that the Tompkins’ work wasn’t without criticism. They were accused of land grabs or of not involving local communities early enough, for example. And when you speak with the people who lived through those early years of building the Rewilding teams, they don’t sugarcoat the struggle. Trust had to be earned and deep, emotional tension showed up everywhere. But standing inside these restored ecosystems today, the outcome is simply undeniable.
Pride is a word we’ve heard a lot of over the course of those 8 weeks. It’s returned to places once written off and places that were hardly on a global map. And the closer we’ve gotten to the teams on the ground, the more we’ve come to learn that the number one driver of success has been local ownership. Rewilding only works when communities see themselves in the future of these landscapes and must never feel displaced by it.

After traveling through 45+ countries, 250 locations, and speaking with nearly 3,000 people working towards a more sustainable future, I’ve come to realize growth means nothing if it harms the communities and ecosystems that make it possible in the first place. The people doing the hardest work—fishers, farmers, Indigenous leaders, grassroots conservationists—have shown me that true progress is defined by how that scale shapes the world around it.
So what can the next generation of business leaders learn from this?
Use capital as a lever: The Tompkins treated wealth as a tool. Money, in their world, was something to deploy with intention. They redirected their financial success outward, not inward. Imagine how differently our world might look if more business leaders viewed their balance sheets as a means to shape healthier futures?
Stretch your timeline: While most companies obsess over shareholder value, the Tompkins were thinking in generations. They invested in ecosystems knowing they might not live to see the impact. And yet, that long-range mindset is exactly why the work is still expanding. The businesses that will endure the next century are going to be the ones building with an eye on what a sustainable horizon looks like.

Lead by releasing: Their greatest measure of success was what Doug and Kris gave back. Donating millions of acres to the public did not show up as a loss or a tax write off. It was actually the whole point. Sometimes the most powerful form of leadership is knowing when to hand over the keys.
Don’t wait for perfection: The Tompkins and their teams were criticized, and rather harshly for that matter, early days. They made mistakes and were categorically misunderstood. But that fueled the fire. Progress was the most used word when talking to the on-ground teams about what Doug stood for. If you’re waiting for a flawless plan or unanimous approval, you’ll never do anything meaningful.

I’m currently writing this somewhere between Argentina and Brazil, on our final week in the field with the Jaguar Rivers Initiative. I’ve found myself rethinking what power and influence are actually for as we drive through these countries once so wild we can hardly visualize what it means in our modern world. Hearing those who knew Doug describe the kind of leader he was has forced me to look inward. At the kind of impact I want to leave behind. We spend so much energy in business chasing perception—titles, property, status, awards. But what does it all mean if the resources beneath our feet disappear?
Legacy is built through the choices we make about where our skills, capital, time, and effort go. It’s built by uplifting the communities who need it most and inspiring others to carry the work forward long after we’re gone. The question no longer is whether we can make a difference. We already know how. It’s whether we will rise up and choose to do so.

REWILDING ARGENTINA

Sofia Heinonen (Executive Director) – Sofía Heinonen was born and raised in Buenos Aires, Argentina, where she trained as a biologist. An activist by nature, she has spent over thirty years designing large-scale, long-term projects for the creation of protected areas and the restoration of ecosystems. She worked for the Wildlife Foundation and the National Parks Administration before joining the Iberá Project in 2005, led by Doug and Kris Tompkins (CLT Argentina), which was later continued by Rewilding Argentina. She is currently the Executive Director of Rewilding Argentina, where she leads four projects covering more than one million hectares and a team of over two hundred people. In 2022, she was recognized by the BBC as one of the 100 most influential women in the world.

Sebastian Di Martino (Director of Conservation) – Sebastián earned his degree in Biology from the National University of La Plata (Argentina) and a Master’s degree in Protected Natural Areas from the Autonomous University of Madrid (Spain). He admires the revolution that rewilding is bringing to the world of conservation and is convinced that this strategy should be widely used in Argentina to restore its natural environments, which are now largely defaunated. Since the age of 13, he has participated in the activities of environmental organizations, and his work has always been linked to nature conservation, especially at the Directorate of Protected Natural Areas of the province of Neuquén. Since 2015, he has been the Conservation Director of Rewilding Argentina and is in charge of the species and habitat restoration projects we carry out.

Lucila Masera (Director of Strategy and Alliances) – Lucila studied chemical engineering in Buenos Aires and environmental engineering in Madrid, where she worked as a consultant for a private forestry agency. In 2017, she began working at Rewilding Argentina, where she was one of the founders of the marine conservation program, with the goal of achieving protection for at least 10% of the Argentine Sea. She has been the Director of Strategy and Development at our organization since 2018, leading projects around the world.

Emiliano Donadío (Scientific Director) – Emiliano is a biologist who grew up in Argentine Patagonia, where he developed a strong connection with nature. After graduating from the National University of La Plata, he earned a Master’s degree in Zoology and a PhD in Ecology from the University of Wyoming, USA.

Emiliano participates in the design, implementation, and monitoring of the Foundation’s research and restoration projects.
POR EL MAR

Martina Sasso (Co-founder & CEO) – Martina’s passion for the ocean is deeply rooted in her family history. Her mother, a sailboat captain, and her grandfather, a submariner, filled her childhood with sea stories. She recalls that her books, summers, friends—everything had a scent of the sea. Before founding PEM, Martina started her career as a creative advertiser, but her love for nature led her to create a life dedicated to the environment. She spent years transforming the Buenos Aires Zoo into an ecological park, relocating animals to sanctuaries. She also advocated for Marine World to do the same but without success. This experience ignited her determination to protect marine life, leading her to found and direct the marine program “No Blue, No Green” at Rewilding Argentina. On this path, Martina became deeply involved in the creation of Argentina’s first MPAs, and understanding the necessity of an organisation fully dedicated to marine conservation, she set off to found PEM. As co-founder and CEO, her role involves managing institutional relationships, dreaming of the organisation’s future, and fundraising to make those dreams a reality. She also guides team leaders in their quest for conservation, continuing to fill her life with sea stories while making history in protecting it.

Maia Gutierrez Bustamante (Co-founder & COO) – Maia’s love for the ocean is a cherished family heritage. Her grandparents were avid divers and sailors, living and spending most of their time by the sea. They passed their passion and love for the ocean through generations. When asked about the experiences that forged her bond with the ocean, Maia explains it was part of her upbringing. For years, Maia led her own 360 agency dedicated to NGOs, together with her sister Lara, and working closely with lifelong friend Martina, with whom they also advocated for the creation of Argentina’s first MPAs. In 2022, after much effort and collaborative work, they co-founded PEM with the dream of implementing a shared vision for marine conservation. As Co-Founder and Impact Director, Maia shapes the organisation’s values, sets the course for macro goals, and advises teams on strategic matters, ensuring PEM is surfing in the pocket of the wave of change.

Lara Gutierrez Bustamante (Co-founder & CFO) – Lara’s journey with PEM began before it had a name. Following the creation of Argentina’s first MPAs after two years of dedicated work, Lara and the team drove back from Congress feeling that anything was possible. That day, in celebration, they envisioned the future and dreamt about PEM. Today, as co-founder, Lara ensures PEM stays true to its innovative roots, and as finance director, she oversees the organisation’s economic and financial planning. Before founding PEM, she co-founded the marine conservation program “No Blue, No Green” alongside Maia and Martina and led a 360° marketing agency dedicated to NGOs, where she also handled financial planning. Her background in fine arts and design thinking combined with her passion for numbers have made it easy for her to build large systems, –such as the organisation itself–, while still keeping an eye on creativity.

Cecilia Dhers (Deputy Executive Director) – Cecilia began working with PEM because of a thermos. Long story short, PEM´s Founder, Lara, forgot hers at an event where they met, and, aware that they lived blocks away, Cecilia took it with her. Three months later, when Lara finally went by to pick it up, PEM was seeking a coordinator for the Global Salmon Farming Resistance (GSFR), and Cecilia was seeking change. Before this, with a background in politics and international relations, she worked for the government which taught her how to master a foundational pillar in her new role: the collaboration with local communities. Today, Cecilia has grown to be deputy executive director and she is responsible for the alignment across all teams. From returning a thermos back home, to bringing teams and people together, Cecilia is always a bridge and helps PEM connect today’s hopes with tomorrow’s reality.

Dr. Cristian Lagger (Science & Conservation Director) – Cristian was only 12 when he first put on a diving mask and jumped into the sea. From that moment on, he knew his life would be tied to the ocean. He holds a PhD in Biological Sciences from the National University of Córdoba and works as a permanent researcher at the National Scientific and Technical Research Council (CONICET) within the Marine Ecology Laboratory (IDEA), one of Argentina’s leading centers for coastal and underwater research. Throughout his career, he has dedicated himself to studying marine biodiversity and ocean conservation. His research and National Geographic Explorer work have taken him on numerous scientific expeditions to explore and document marine ecosystems. As a scientific diver and underwater cameraman, Cristian has also produced a wide range of audiovisual content to foster empathy for marine conservation. As Director of Science and Conservation at PEM, Cristian plans and develops conservation strategies, defines lines of research across projects, and leads the conservation team. His favorite part of the job is leading scientific expeditions, where he dives to document the ever-changing marine life that has captivated him since childhood.
