Episode summary

Today’s a third-time return with Paul Rosolie, naturalist, explorer, writer, and fierce protector of the Amazon. His new book, Jungle Keeper, drops in days—go pre-order—and if you want to help his team safeguard the rainforest, visit junglekeepers.org or catch the New York gala on January twenty-two.

We once recorded a show in the jungle and filmed a ton of chaotic footage I still dream of cutting into a raw travel vlog, so thanks for the patience while I keep tinkering. Now to the wild updates: 130,000 acres saved, a push for approximately 200,000 more, rising threats from narcos, illegal loggers, gold miners, and a rare encounter with an uncontacted tribe at the heart of his new book, which opens with the killing of two loggers in August 2024—who are these Moshkopiro warriors?

Across the basin there are likely thousands of isolated clans, and outsiders who ignore warnings learn how lethal the forest can be. These hunters move unseen and can drop a spider monkey from high canopy with long bamboo arrows before you even register danger.

Those arrows you showed on Instagram look like spears—huge, almost as tall as a person.

They fire-harden the bamboo, sharpen it to knife-edge, twist the fletching so it spins, and bind it with plant fibers—seven feet of precision and craft. It’s staggering that this lives alongside airplanes and smartphones.

We take for granted electricity, metals, machines, roads, weapons, medicine—things they don’t have—while they hold deep jungle knowledge we barely grasp.

There’s no metalwork or pottery, and without those they’ve never seen water boil or freeze; even a camera feels supernatural. Their world is radically simple and self-sufficient.

So when chainsaws roar in the distance, how do they interpret that intrusion?

As something destructive and ominous, and in our meeting they made one thing crystal clear despite the language gap: why are your people cutting the trees?

Take us into your October 2024 encounter.

This is a high tributary on the western edge of the Amazon, a river so remote the government once called the tribes a myth; we now protect long stretches of it. An indigenous community rang a satellite phone saying the tribe had emerged, so we ditched meetings, boarded a boat with Ignacio—who survived an arrow to the head in 2019—and ran a two-day route in one night through a lightning storm, steering by the shine of caiman eyes and jumping falls in the dark.

At dawn we found fresh tracks and an anthropologist calling to them in the overlapping dialect, inviting peace; Ignacio told us to stay put because they’d return. Soon people were shouting as a line of naked warriors walked the beach with giant bows, and fear met duty as we documented while planning where to run if the arrows flew.

Past contacts have been violent, so what did you sense in their approach—attack or dialogue?

They moved in tense and ready, while our anthropologist asked them to set bows down so we could talk; we floated over a canoe loaded with plantains, which they seized in a rush. Meanwhile the women slipped behind us, raiding yucca and bananas without a sound, and that’s when it hit us that we were fully surrounded.

So it was peace with pressure—what did they want to know?

They asked how to tell helpers from tree-cutters and why anyone would fell a giant tree, which to them felt like desecration. They demanded more bananas and rope—some wore paracord looted from camps—and our translator believed this particular band was first contact for him.

What do they call themselves, and did you see signs of leadership or coded gestures?

They refer to themselves as Nomole, the brothers; two men carried most of the talking, with face paint and hand signs that clearly meant something. After gifts they loosened up, and one even wore a Junglekeepers shirt and pants we passed across the river.

Our translator asked me to step forward and show open hands, and when I did they sang back—an impossibly delicate pause in history.

Then came the ambush the next morning—why do you think it flipped?

They swarmed a passing boat, and an arrow entered above George’s scapula and exited near his belly; he lived after a medevac. Whether it was fear, the sound of the motor, or strict taboos around women, we just don’t know.

Those large necklaces and the machete—what do you make of them?

Two wore grapefruit-sized Brazil-nut containers ringed with what looked like teeth, guarded carefully from water, which suggests medicine or a totem. They absolutely understand metal and raid for machetes when they can.

How do they communicate across distance?

They mimic animal calls and use whistles as coded signals; on a later patrol Ignacio whistled, they whistled back, and our team backed out quickly.

Secrecy and survival seem intertwined, and life there is brutally hard.

It’s a savage existence of hunting monkeys and turtles, raids, parasites, and hunger, and silence may be enforced by necessity as much as tradition.

The jungle invites spirituality—do you sense a belief system?

They must carry origin stories and a cosmology untouched by nations, and watching them step from the trees felt like time opening.

You might already be a new myth in their stories.

They’ll remember the bearded gringo with the big nose, for better or worse.

Let’s ground this in the mission—land, protection, and the path forward.

We’ve secured 130,000 acres and are pushing for around 200,000 more that aligns with their roaming grounds; we buy land before loggers and narcos do, hire former extractive workers as rangers, and keep the river wild so the Nomole can choose isolation on their terms.

The goal is to shield the deep jungle from forces that would level it.

This is a crown-jewel watershed where nature and culture endure, and thousands of monthly donors now fund local rangers and indigenous futures while we keep our footprint tiny—thank you for powering that.

And the team matters—Stefan’s the systems brain who turns support into action fast.

He built the engine we lacked and keeps ops humming while we work the river.

Quick diet question—what do the uncontacted eat?

Monkeys, turtles and eggs, and small game like paca and capybara; turtle shells serve as bowls in temporary camps, and their fire-making in constant wetness must be extraordinary.

That photo of a little girl eating monkey is uncanny because the face looks so human.

I once shared a monkey head with a six-year-old who loved it, and it’s unsettling precisely because it resembles us.

With some distance now, when you think about that historic encounter, what stays with you?

Being with people who live fully inside the forest reset my sense of what’s normal; they rely on nature the way we rely on tap water, while I come back to cities and marvel that we turned rocks and oil into flying machines and cameras, and they keep their history alive with voices instead of books.

Both worlds are miraculous, and your writing pushes against the hopeless, anti‑human mood; with that, tell me about Jane and the mark she left on you after she passed.

I grew up hearing Jane’s stories, then handed her two draft chapters in a manila envelope after a talk, and she actually read them and offered to endorse the book that didn’t exist yet, which unlocked a publisher, launched Mother of God, and set off the chain that became Junglekeepers.

She did that for countless people, and now you carry that same duty when young folks come to you with big dreams.

What would you tell a young person who wants to jump into adventure and conservation?

Go where the work is and start anywhere, even if it means washing dishes to get inside the kitchen, because there was no clear path for me, just years of learning from locals, failing forward, and doing it for love long before any job title showed up.

You’ve also been honest about the toll, the seasons when it feels like the tide is against you and the winning is scarce.

We’ve watched forest turn to ash and hauled animals from flames while funding sputtered, and the weight of knowing a thousand‑year tree lives or dies on whether you outpace a chainsaw can feel crushing, yet momentum has grown and protecting one hundred thirty thousand acres made room for a fragile kind of hope.

Then came a new enemy along the river, with coca fields and hidden runways.

A drone flight over a clearing turned into a chase, police friends geared up and saved us, and hours later one of them was killed while unloading a boat; soon after, gunmen blocked a road asking for JJ and the gringo with the drone, phones later revealed orders to shoot us on sight, and life shifted into living with a target on our backs.

Remote country becomes lawless fast; how have you handled the fear?

Not gracefully, because the calls at night spike my heart and the dreams turn violent, and it’s hard to square the mission of saving trees and tribes with being hunted by people who know your name and wait for you to let your guard down.

What does their network look like, and how do you even detect airstrips under the canopy while a global drug market keeps pumping money into the system?

They front small loans to the poorest, flip those clearings into safe houses, and cut runways that stay invisible from above because the crowns still meet, so we’re now exploring long‑endurance imaging drones while asking under‑resourced police to make multi‑day runs into gunfire.

Roads are spidering toward uncontacted territory, our post about a northern incursion raised one hundred fifty thousand dollars in a flash, but fully sealing the corridor needs about twenty million dollars or one fearless benefactor, because on our land the police can act immediately while in the gray zones they stall and traffickers hide.

Take me to the tree you once thought was unclimbable and the moment you saw the mist river at dawn.

I hauled myself up a giant trunk in the dark, placing sparse protection and fighting lactic acid, and when the howlers started and first light hit the canopy, vapor lifted and flowed like a golden river over the forest as macaws rose, and it felt like being handed a secret by the tree itself.

You capture scenes like that beautifully; tell me about the macaws and their ironwood condos.

They bicker loud and love hard, and because only ancient ironwoods form the right hollows, just a small slice of the population breeds each year, which makes them precious to both the forest and the ecotourism economy that gives locals dignified work.

About that anaconda around your neck, how did you walk away from that?

She was a nineteen‑footer mid‑shed with eerie blue eyes and the kind of power that tossed ten people like driftwood, and although giant females usually avoid a fight, give them purchase and they fold you like a snack, which is why we work as a team, measure quickly, and let them go.

You dance on the edge but seem to radiate calm with animals.

Calm helps, but without partners and a plan a snake that size will finish you, because constriction is physics, not bravado.

Back to the floating forest and the tale of a horned giant; how did you move from doubt to belief?

Local stories usually point to something real, like the time a “spiky” snake turned out to be coated in algae, and that rafted world is so isolated it breeds oddities while sheltering leviathans under mats and palms.

People should see the spider monkey rescue; it looks like the two of you understand each other.

She was losing the fight with currents until I offered a paddle and soft signals, she studied my face, chose to trust, rode high out of the water, and then sprang into the forest without looking back.

Outside the human threat, when have animals truly put you in danger?

The small things kill fastest through stings and infection, while big cats mostly ignore you, but a tormented male elephant in India tried to flatten me and I barely escaped by tumbling into a stream as he shattered trees above.

When the dust settles, we should chase wild elephants and drift the Amazon; before we do, how do you actually write these scenes?

I journal on paper every day to trap details and feeling, then when a scene starts burning in my head I pull the right notebook and build it on the laptop from those inked moments.

It’s hard to bottle that experience in words, so do you draft a ton and keep reshaping?

I treat writing like sculpting clay: dump everything on the page by hand with eyes half closed, then carve it over dozens of passes; the last book had me editing after ten-hour jungle days, so now I write and polish chapters as they happen, send them to my sister who’s a fierce editor, and bank them for the next book.

I’ve got Mother of God and Jungle Keeper out, Endgame underway, and a chapter from a brutal trip upriver where oil crews, missionaries, and a newly contacted group collided; JJ and I felt people weighing whether it was worth robbing or worse, he accidentally introduced money to a villager, and we kept hearing the same wild warning about dolphins that turned dark humor into a running theme.

Jungle rule: believe the locals about danger, no matter how strange it sounds.

Exactly—those warnings were their way of looking out for us.

You riff across styles—sometimes maximal, sometimes spare—who feeds that?

I love stretching with lush metaphors, but readers often prefer a clean, Bourdain-like pace that just tells the story and saves the rare flourish for when it counts.

You also hit that Hemingway mode where short lines and silence do the heavy lifting.

Simple sentences can carry a whole afternoon in your senses, and stacked together they pull you into the scene; that’s the kind of plain beauty I keep coming back to.

Have you been using LLMs much? They’re impressive, but something human seems missing.

I can often spot AI prose even when I can’t say how, and it makes me think about what Fitzgerald nails—the exactness of a lived moment—which models can imitate in style but not in soul; you told me human-made art will only grow in value as bots flood the feed, and I didn’t expect that, but I think you’re right.

As bots get more convincing online, we’ll crave the real thing—art in rooms, conversations face to face, people being raw and present.

Even now, movies feel overpolished and safe; I miss messy risks.

Let independent film bring back danger and grit.

Everyone’s in streaming shows, and I’m rewatching old films; it’s like that Dead Poets Society moment where you toss out the neat scoring chart and remember that art’s alive, not a graph.

Robin Williams embodied that messy brilliance; it still hurts to think how a mind like that can be lost, even knowing he was ill—life can be terrifying.

A friend met him as a kid in New York, ran for a napkin, and Robin waited despite a rushed manager; that small kindness stuck for life.

Those tiny moments are everything.

They are, and you can add a little magic on purpose—like waking your kid at midnight with a candle and warm tea to watch a sky full of stars.

Good old Dax is why we met; he gave me his book, Echoes from Eden, with a note about defending Earth’s last wild places, and he rocks an even better beard than you.

He’s backed the work in the Amazon, Sea Shepherd, orangutans, sea turtles, and actually visits the sites; that book reads like a conservation field report because he went and looked with his own eyes.

It’s not just funding—it’s belief.

During COVID I crashed, quit in despair, and four days later Dax called with a ten-year commitment to Jungle Keepers; beyond money for fuel and boots, he brought operating discipline, and we went from a chaotic startup to ranger boats, systems, reports, and results people can see.

Shout-out to Stefano and to Dan—life with Dan—whose patience and love for the wild lets him follow you into the dark and still get the shot.

Dan heard our first talk, joined an expedition, impressed everyone, and now we work together; he’ll rise before dawn for side-light on a tree boa, wait days at the clay lick for the macaw burst, hike with heavy glass, and keep going when lenses fog and the trail fights back.

You draw great people because the mission’s alive and urgent.

It’s become a team I can’t believe I get to lead.

This is intense work—what’s your plan as you get older?

We have about a year and a half to lock down this river or the window closes; we’re at roughly one hundred thirty thousand acres, aiming for three hundred thousand, and I think momentum will break and we’ll tell the story in a film about saving the wildest place left.

After that I want kids, a PhD, to train others to do this, and to keep writing and guiding without carrying the ring forever; I owe safety to the creatures I know by name, and I’m ready to trade the Blood Diamond grind for a professor’s life with a little Indiana Jones, minus the supernatural finish.

Thank you for giving it everything and please don’t die doing it; it’s an honor to be your friend, and I hope we get many more talks.

Your first invite changed my life and kept me going when hope ran thin; you brought people to this mission and helped make it real.

Thank you for today—now let’s go eat, and thanks for listening to this conversation with Paul Rosolie.
