Key Takeaways from Episode 1 of Rewilding Amazonia

• The Amazon has experienced repeating cycles of extraction and exploitation for over 500 years—from rubber slavery to fur booms to current criminal economies
• 90% of the Amazon’s Indigenous population (8-20 million people) died from European diseases after 1492, causing forest regrowth that measurably cooled Earth’s temperature
• 23 million animals were killed for the fur trade between 1904-1969, devastating species like jaguars, giant otters, and black caiman
• The Trans-Amazonian Highway (1970s) was supposed to bring progress but instead accelerated deforestation and forced Indigenous assimilation
• Chico Mendes’ 1988 assassination sparked global awareness but also demonstrated the lethal risks faced by environmental defenders
• The 1992 Earth Summit created extensive protected areas on paper, but criminal organizations now control many of these zones on the ground
• The Amazon is at 17% deforestation; scientists warn 20-25% loss could trigger irreversible collapse into savanna
• Despite corruption and violence, people across the Amazon are finding ways to rewild the forest—forming the basis of this 8-episode series

Magali’s Impossible Choice

Magali: “ The government is an illegal miner, so what are you going to ask it? Nothing.”

That’s Magali, a wildlife rescuer in the Peruvian Amazon. I couldn’t quite process when she told me this: in her region, she can’t release rescued animals into protected reserves because illegal miners are operating inside them. She can’t report it to local authorities because those same authorities are profiting from the mining.

Corruption has taken hold of certain parts of the Amazon and the people who are supposed to protect the forest…are the ones destroying it.

That should be the end of the story. If authorities won’t help, then what’s the point?

But that’s where our story begins…with Magali. She’s still there, rescuing wildlife at an accelerating rate, and then releasing them on private concessions protected by conservation. 

This is Rewilding Amazonia, an investigative nature podcast series by Rewildology. I’m Brooke Mitchell, the principal investigator of this story and your guide. Over the next eight episodes, I’m going to share everything I discovered—the shocking, the revelatory, and the inspiring. You’ll journey with me across the Amazon basin and meet the people who refuse to give up and believe that the Amazon can thrive once more.

Let’s begin.

The Investigation Begins

A Question that Started It All

In the summer of 2025, Rosa Espinoza who is a chemical biologist from Peru, asked me something that shifted how I see the world:

Rosa: “Do you like coffee? Chocolate? Cheese? Ice cream? Furniture? That your weather patterns are slightly predictable? Every aspect of our lives—food, medicine, agriculture, cosmetics, clothing, energy, climate—are in one way or another, connected to the Amazon Forest.“

I couldn’t unsee the Amazon’s influence after that—my favorite coffee imported from Peru, the dark chocolate from Ecuador in my freezer, and as I’m sitting here writing this, twelve inches of snow on the ground from a record-breaking storm. The Amazon wasn’t “over there” anymore—it was here, affecting my daily life in ways I’d never noticed before.

November 2025—COP30

Then in November 2025, the world came together in Belém, Brazil for COP30, the United Nations Climate Summit, to discuss the future of the Amazon. My social media feeds were flooded with images of protests, politicians making commitments, Indigenous leaders demanding action, and I found myself wondering: were these commitments real, or were they just more promises that would quietly disappear once the cameras left and everyone went home?

So I did what any curious scientist would do—I started reaching out to people who work in the Amazon: scientists in Brazil, wildlife rescuers in Peru, veterinarians in Colombia, human rights activists in Venezuela, lawyers combating environmental crimes. I asked them all the same question: “How do we rewild the Amazon?”

And what I discovered is that the answer is far more complicated than I ever imagined, because what started as a question about conservation turned into an investigation about corruption, economics, violence, and…hope.

So how did we get here? How can protections and destruction exist simultaneously in the same forest? To understand that, I needed to go back—way back—because the patterns I was seeing have been repeating for centuries.

Historical Context: Understanding the Amazon

The Amazon Basin

First, let’s start with what the Amazon is. The Amazon Rainforest is the largest rainforest on Earth, spanning 6.7 million square kilometers—roughly the size of Australia—across eight countries and one French department. It’s home to at least 10% of the world’s known species—and likely millions more yet to be discovered. About 47 million people live in the Basin, including 2.2 million people from 410 distinct Indigenous nations.

Ancient Peoples and Sophisticated Societies

Archeologists estimate that humans settled in the Amazon around 11,000 years ago, and for millennia, these ancient peoples actively managed the forest, leaving behind evidence of complex societies, urban settlements, and sophisticated agricultural systems that sustained millions of people.

European Contact and Catastrophic Death

But in 1492, Christopher Columbus arrived on the shores of the Americas. Not only did Columbus and subsequent Spanish conquistadors bring horses and powerful weapons, but they also brought deadly diseases that ancient Native Americans had no immunity against. After contact, measles, influenza, smallpox, typhus, and other diseases spread like wildfire, and the death toll was catastrophic. Across the Americas, an estimated 56 million people died following Europeans contact. In the Amazon specifically, the population before contact was estimated to have been between 8 and 20 million people, and after European arrival, 90% of them perished—90%! The population collapsed so dramatically that the regrowth of the forest and carbon absorption over the following century caused a measurable cooling in the Earth’s global temperature.

When I found these numbers in peer-reviewed research, I had to stop and sit with them for a while. I knew European diseases had devastated Native populations across the Americas, but I didn’t fully grasp the scale. I also wasn’t aware that people had actively cultivated parts of the Amazon for millennia, especially along rivers and in floodplains where they built cities, terraced fields, and managed orchards. In the areas that weren’t cultivated, ancient Amazonians left the forest alone, using the space for hunting and gathering. The Amazon was never an untouched, pristine wilderness as I grew up believing. 

Why the Amazon Resisted Conquest

So by the time the Spanish turned their attention to the Amazon in the 1540s, they were walking into a landscape that had just experienced the greatest human catastrophe in its history. But even then, the Amazon resisted conquest. How? Geography, a very dangerous forest, and decentralized societies.

The Amazon never fell under the rule of one centralized power for the Spanish to overthrow, like the Incas or Aztecs. The region was a mosaic of hundreds of distinct nations spread across millions of kilometers of dense rainforest connected by rivers that could take weeks to navigate.

And the forest itself was deadly to Europeans. Malaria, yellow fever, and parasites—diseases that Native Amazonians had adapted to over millennia—killed Spanish and Portuguese soldiers who had no immunity. The unrelenting heat and humidity weakened their bodies, and the dense forest didn’t allow for the use of pack animals or cavalry.

So the Spanish and Portuguese established some outposts along the major rivers where they could control trade routes. For centuries, the vast interior remained what they called “terra incognita”—unknown land, unconquered territory. Not because it was empty, but because the people who lived there successfully resisted conquest longer than almost anywhere else.

How the Amazon Got Its Name

The Amazon got its name from the Spanish conquistador Francisco de Orellana (or-a-yana), who led the first European expedition down the Amazon River in 1542. They were searching for El Dorado, the mythical city of gold, and along their journey, they encountered fierce Indigenous warriors, some of whom were women. The Spanish were steeped in Greek mythology and compared the fighters to the Amazons—the legendary warrior women from ancient Greek stories. The name stuck, and outsiders from then on treated the Amazon as a unified place, ripe for extraction.

Nation-States and the Shift to Exploitation

Borders Defined, Control Established

When the Spanish and Portuguese empires fell in the early 1800s, several nation-states were founded, and the Amazon was divided by country borders. But these newly independent nations were weak, and the Amazon remained a lawless, wild frontier. To understand the next series of events, I talked to Daniel Aristizábal from the Amazon Conservation Team, who works with isolated Indigenous peoples in the Colombian Amazon—communities that have chosen to remain uncontacted with the outside world. 

Daniel: “The nation states developed and the nation states took over the interest of protecting, not protecting, but controlling the Amazon over the colonial powers. So I’m talking about Brazil, I’m talking Peru, Columbia, et cetera. Borders in the Amazon got defined, which were very late in respect to other borders of South America, right, because the Amazon was the unknown.”

That mindset shift—from unconquerable wilderness to exploitable resource—opened the door for the extraction booms that followed.

The Rubber Boom: Slavery Returns to the Amazon

Europe’s Demand, the Amazon’s Suffering

The first major boom came in the 1880s. Europe and America were industrializing, and they desperately needed rubber. They turned their eyes to the Amazon, which had millions of wild rubber trees, and partnered with private enterprises that extracted and exported rubber. The spike in demand created a labor shortage that the business owners were determined to fill, no matter the cost.  

Daniel: “One of the big waves of people isolating was in the late 1800s and early 1900s with the rubber boom in the Amazon. Europe discovered the way to make waterproof jackets, tires for cars, and the war effort in Europe—both wars and other wars in Europe—greatly increased the demand for rubber, for army boots, for tires, for tanks, for jeeps, for raincoats, you name it. So again, Europe’s hunger for power and war created a huge demand of slavery in the Amazon. There was a huge increase of slavery to extract the rubber from the rubber trees. This caused huge human rights violations. The whole world had already abolished slavery, but there was slavery in the Amazon, and this caused the biggest wave of indigenous groups going into the forest and escaping.”

Debt Peonage and Terror

The enterprises recruited poor migrants with promises of quick riches and advances on supplies, but many Indigenous peoples were coerced through armed raids where crews attacked villages, killed resisters, and kidnapped workers to force labor. Once ensnared, people became trapped in debt peonage, a de facto slavery system. Rubber bosses ran company shops where workers bought essentials like food, clothes, and tools at massively inflated prices, while rubber credits were set unfairly low—debts ballooned endlessly and often passed to families or were sold along with the worker. In Brazil’s aviamento system, this bondage dominated remote concessions. In Peru’s Putumayo region, under bosses like Julio César Arana, it escalated to terror: torture, mutilation, starvation, or execution for unmet quotas. Throughout the frontier, the state rarely intervened—remoteness, corruption, and rubber profits left authorities complicit or absent.

Boom, Bust, and the World War II Revival

The rubber boom eventually collapsed in the 1920s when the British smuggled rubber tree seeds to Malaysia and undercut Amazon prices. The bust left ghost towns, indebted families, and deeper isolation for fleeing groups. But the Amazon didn’t stay quiet. 

During World War II, when Japan cut off Allied access to Asian rubber plantations, the U.S. turned back to the Amazon. Brazil’s government recruited tens of thousands of workers—many poor migrants from the drought-hit Northeast—under the ‘Battle for Rubber’ campaign. They were promised heroism and riches, but faced familiar hardships: disease, isolation in the forest, and grueling labor with little lasting reward. Production spiked briefly, but the cycle of boom and bust repeated itself on a smaller scale.

The Fur Boom: 23 Million Animals Lost

After World War II, the Amazon enjoyed a couple of decades of relative quiet. Then, in the 1960s, high fashion in Europe and the United States ignited a new commercial hunting boom—demanding exotic furs and feathers for luxury coats and accessories. Businessmen turned to Indigenous hunters, whose superior tracking skills made them the perfect targets.

Europe’s Demand, the Amazon’s Suffering

Daniel explained how it unfolded:

Daniel: “ This coincided more or less with the 1960s when there was a huge fur boom in the Amazon. So, uh, skins right? Jaguars, otters, monkeys, you know, feathers. All this for the “Haute Couture” in Europe and great fashion in the United States. All of these skins for like coats and stuff like that.”

As he spoke, the pattern snapped into focus for me again: global luxury demand pulling in local exploitation—just like rubber, only this time it was living animals disappearing. Traders often trapped Indigenous hunters in debt systems eerily similar to the old aviamento—advancing supplies at inflated prices, paying almost nothing for the pelts, and creating debts that lasted lifetimes and passed to children.

The Animal Body Count

Between 1904 and 1969, an estimated 23 million animals from at least 20 species were killed for hide exports in the western Brazilian Amazon alone, with a brutal peak in the 1960s. Aquatic species like giant otters and black caiman collapsed almost completely; terrestrial ones like jaguars and peccaries held on longer but still took devastating hits.

When those numbers hit me—23 million animals gone for coats and handbags—I had to stop. Fashion didn’t just empty rivers and forests; it pushed more pressure into the remote corners where people had already fled to escape exactly this kind of intrusion.

Pacification: Forced Assimilation in the Name of Progress

Brazil’s Integration Project

With the fur boom winding down—thanks to international bans like CITES in 1975—I thought maybe the Amazon would finally catch its breath. But as I kept reading timelines and cross-referencing Daniel’s insights on nation-state control, I realized the quiet was an illusion. The real acceleration was coming from Brasília, not Paris or New York.

Brazil’s military dictatorship, which ruled from the 1964 coup until 1985, looked at the vast, sparsely populated Amazon and saw vulnerability—unoccupied borders that could invite foreign claims or instability. Their answer? Integrate it. Populate it. Conquer it. 

The Trans-Amazonian Highway

The centerpiece was the Trans-Amazonian Highway—a colossal project announced in 1970. Thousands of kilometers carved straight through the rainforest, from the Atlantic coast nearly to Peru. President Emílio Médici sold it as salvation: land and jobs for poor families fleeing drought in the Northeast. ‘Land without men for men without land.’ They recruited settlers with promises of 250-acre plots, loans, even salaries. It sounded like progress.

Daniel: “During this time, these governments took it upon themselves to contact these groups, particularly in Brazil. The heroes in Brazil are those who conquered the forest, contacted the Indians people, and made them part of the Brazilian project, called sertanistas, whose job was to pacify the Indians.”

Hearing that phrase—’pacify’—gave me chills. It wasn’t protection; it was forced assimilation. The highway became the tool: opening access for settlement, logging, ranching—and for ‘pacification’ teams to reach isolated communities, often bringing disease and displacement along with roads.

Collapse and Deforestation Explosion

What I uncovered next was heartbreaking. The project collapsed under its own weight. Amazon soils are thin and nutrient-poor—fertility comes from the living forest, not the dirt. Crops failed after a season or two, malaria surged, and roads washed out during the rains, stranding people. Most settlers abandoned their plots, leaving debt and cleared land that powerful ranchers and loggers quickly claimed.

Deforestation didn’t just rise afterwards—it exploded. Before the highway, clearing was scattered and small-scale. But after, annual rates climbed dramatically through the 1970s and 1980s—tens of thousands of square kilometers lost each year. Ninety-five percent of deforestation happens within a few kilometers of a road. Feeder roads branched out like cracks, and the forest started fracturing.

Chico Mendes: A Voice for the Forest

But not everyone accepted it. A rubber tapper named Chico Mendes began organizing his fellow seringueiros (tappers) against the ranchers and loggers flooding in along these new frontiers. He built alliances with Indigenous communities, pushed for sustainable extractive reserves—protected areas where people could harvest rubber, nuts, and fruits without destroying the trees. He took his fight international, winning awards and drawing global eyes to the Amazon.

In 1988, just as momentum was building, he was assassinated—shot in his backyard by gunmen tied to local cattle interests. He was 44.

His murder shocked the world. It sparked outrage, helped create the first extractive reserves (including one named for him), and turned him into a martyr for the forest. But it also showed me something chilling: when someone challenges the pattern head-on, the backlash can be lethal.

Conservation on Paper: The 1992 Earth Summit

Global Outrage Turns to Action

Chico Mendes’ murder in 1988 didn’t just end one life—it lit a fuse. The world finally turned its eyes to the Amazon. As I traced the headlines and reports from that time, I could almost feel the shift: outrage turned into action.

Just four years later, in 1992, Brazil hosted the Earth Summit in Rio—the largest environmental gathering the planet had ever seen. Leaders from nearly every country gathered to promise something different: sustainable development, biodiversity protection, and real commitments to stop the bleeding.

A Wave of Legal Safeguards

From that momentum came a wave of legal safeguards. Vast new national parks and protected areas were created or expanded. Indigenous territories—long fought for—started getting legally demarcated and titled. Chico’s own vision, extractive reserves, became law: protected zones where rubber tappers, nut gatherers, and traditional communities could harvest from the forest without destroying it.

On paper, the Amazon became one of the most protected ecosystems on Earth—millions of hectares shielded by national legislation and international agreements.

When I looked at those maps with green blocks spreading across the basin, it felt like a turning point. Finally, the laws seemed to match the urgency I’d been hearing from people on the ground.

However, the deeper I dug, the more one question kept rising: What happens when the protections exist on paper… but the reality on the ground is something entirely different?

The Criminal Economy Takes Root

As those declarations were being signed and reserves drawn, another force was already moving in—violently and permanently.

Starting in the 1980s and accelerating through the 1990s, the Amazon became a major cocaine transit corridor. Andean producers needed routes to global markets, and the region’s vast rivers, airstrips, and newly built roads were perfect. Armed groups—FARC and ELN guerrillas from Colombia, paramilitaries, and later Brazilian gangs like the PCC—poured in to control the flow.

This was very different from the rubber or fur booms. Those operators came, extracted, and left when prices crashed. But these new groups didn’t leave. They stayed, and they diversified. Cocaine profits funded illegal gold mining, timber smuggling, and wildlife trafficking—creating full criminal economies.

In remote areas, they became the de facto government and intimidated anyone who resisted. Protected areas on paper? Yes. But on the ground, armed men with guns and radios often held the real power.

The Pattern Continues

As I read papers from the 2000s and 2010s, a pattern became painfully clear: when a new park or reserve was declared, criminals simply adapted by moving operations deeper, bribing officials, or using violence to keep control. The same roads built for “progress” now served as arteries for mercury-laced mining runoff, drug shipments, and timber trucks. Places that were supposed to be sanctuaries became contested zones. And people who resisted were punished. Between 2012 and 2022, almost 2,000 land and environmental defenders were killed worldwide—most of them in Latin America, particularly the Amazon. The message was clear: resist and perish.

Where We Are Now: The Tipping Point

Which brings us back to the present. The original Amazon basin spanned roughly 6.7 million square kilometers, but today, about 17% has been deforested or heavily degraded. Scientists warn we’re approaching a tipping point: somewhere between 20 and 25 percent loss, the rainforest could start transforming into a drier savanna. And in key regions, the rate isn’t slowing—it’s accelerating.

And right in the middle of that narrowing window are those refusing to give up.

People like Magali—who can’t release animals in protected areas, so she finds another way.A foundation in Brazil planting 1.7 billion trees to reconnect 2,600 kilometers of fragmented forest. Indigenous communities partnering with local governments to protect millions of hectares outside the national park system.

And that’s just the beginning.

What’s Coming Next

Over the next seven episodes, you’re going to meet these people and many more. You’ll hear their stories, understand their strategies, and see what rewilding the Amazon actually looks like on the ground.

In the next episode, we’re traveling to the Amazon’s Ghost Forests to meet the people bringing species back from the brink—because you can’t rewild a forest without the animals that make it whole.

This is Rewilding Amazonia. I’m Brooke Mitchell. See you in Episode 2.
