Florida’s waterways are home to beloved and iconic gentle giants, manatees. These half-ton, lumbering mammals – with their wrinkled, whiskered skin and paddle-shaped tails – are believed to have evolved from the same grass-eating land ancestor as elephants over 50 million years ago. Florida manatees are famously playful, sensitive, and inquisitive. They spend much of their lives grazing, cow-like, on meadows of seagrass; congregating in warm-water refuges; expressing emotion through complex chirps, whistles, and squeaks; nursing and caring for their young; nuzzling each other with their noses; hugging with their flippers; and maneuvering slowly at around 3 to 5 miles per hour through the state’s rivers, estuaries, and shallow coastal waters. These remarkably peaceful herbivores have no natural predators and express no aggression towards other creatures. Despite being so gentle and defenseless, they can live more than sixty years in the wild. But, today, few do.
The iconic Florida manatee is facing a multitude of intersecting, human-caused crises. Nearly all of the estimated remaining 7500 Florida manatees have been scarred by boat strikes, while more than half are estimated to have the toxic pesticide glyphosate coursing through their veins. Years of worsening water quality from Florida’s unfettered agricultural pollution and real estate development have resulted in increased toxic algae blooms that block sunlight from reaching the seagrass meadows upon which the manatees depend. Fishing gear entanglement, habitat loss, and climate change are also driving major manatee losses. In 2021, Florida’s manatees died en masse, with a record 1,100 manatees – more than 12 percent of the state’s total manatee population – perishing. Most died of starvation.
It’s hard to imagine a more lovable or compelling creature than a manatee, but enthusiasm is not enough to save them. For manatees to have a chance, that love needs to be translated into enforced protections for both these animals and their habitats.
Our guest, Patrick Rose, has devoted the past 45 years to propelling Florida manatees to public prominence and to advocating on their behalf with extraordinary dedication, creativity, and effectiveness. Rose is the executive director of the Save the Manatee Club. An aquatic biologist, he is one of the world’s leading experts on the Florida manatee. He was the first biologist hired by the State of Florida to do work related to protecting manatees, and has advocated on their behalf before the Florida Legislature, governor, and Cabinet, provided policy guidance and direction for state-wide recovery efforts, and served as a member of every federal manatee recovery team. As one of his colleagues once put it, Rose is the ‘MVP of manatee protection.’ Over the past couple years, as manatees have made headlines for the crises they face, he has served as their spokesperson and much needed champion.
In 2020, poet Aimee Nezhukumatathil published her first nonfiction book, World of Wonders: In Praise of Fireflies, Whale Sharks & Other Astonishments. In the book’s thirty dazzling essays, Nezhukumatathil weaves love stories about being a daughter, a partner, a mother, and a teacher with reverence for wild animals and plants and what they give us – their ability to expand our imagination and empathy, to connect us to others, to unearth memories, to break our habits of thinking, to teach us lessons big and small, and — perhaps most of all — to simply leave us gobsmacked, humbled, and thrilled to remember that creatures like narwhals and newts exist in this world.
At a time when reflection on the natural world is often defined by despair and loss, Nezhukamatathil’s work is exuberant and full of contagious joy for the beauty and kinship that the world still offers us. The daughter of a Filipina mother and a Malayali Indian father, Nezhukamatathil writes about the human and non-human organisms she has learned from and who have shaped her. The peacocks that she fell madly in love with as eight-year-old on her first trip to India, and then proudly drew in class in small town Iowa, only to be reprimanded by her teacher for not drawing an “American” animal. The beloved and lost pet cockatiel, Chico, that her parents spent hours frantically searching for, and eventually found safe and sound on the tip-top of the persimmon tree. The superb bird of paradise whose spectacular courtship moves parallel the ebullient synchronicity of the dance floor at her wedding when the DJ played the “Macarena.” The fireflies that remind her of summer nights with her parents and sister in their Oldsmobile.
The fossil record acts as both a memorial to life’s spectacular possibilities and as a warning to humanity about how fast dominance can become forgotten history, according to our guest, Scottish paleobiologist Dr. Thomas Halliday. Halliday’s research investigates long-term patterns in the fossil record, particularly in mammals. In his magnificent and daring new book Otherlands: A Journey through Earth’s Extinct Worlds, Halliday translates cutting-edge science into vivid portraits of sixteen fossil sites and their inhabitants extending back 550 million years.
In this podcast episode, we speak with Halliday about his travel guide to the history of multicellular life on Earth, the fragility of ecosystems, how entire extinct worlds are reconstructed from remnants in the Earth’s crust, and the importance of realizing that the lives and the worlds that we know were preceded by hundreds of millions of years of other life and other worlds, “simultaneously fabulous yet familiar.”
Humans try hard to control the natural world. We’ve dammed and straightened meandering rivers and filled in wetlands. We’ve transformed primordial forests into farms and turned oceans into highways. Humans and our domestic animals now account for an estimated 96 percent of all terrestrial mammal biomass. Wild mammals account for just four percent. Amid the cataclysms of the Anthropocene, we tend to think of ourselves as the primary shapers of our planet. But for all our efforts to tame, simplify, and cordon off nature, we remain just as beholden to the world’s ecological laws as we were more than 200,000 years ago when Homo Sapiens first emerged.
Like the laws of physics, paying attention to our planet’s biological laws empowers us to understand how the world works and to make predictions about the outcomes of our actions. In his latest book, A Natural History of the Future, Rob Dunn – an extraordinarily creative author and ecologist – warns that continuing to ignore these laws will cause us to fail again and again in our attempts to build a sustainable future for our species.
Dunn makes the case that the human species will survive not by simplifying and isolating, but through embracing biodiversity and living in accordance with the knowledge that we are at the mercy of the law of natural selection, the species-area law, and the diversity-stability law, to name a few examples. These laws aren’t merely fascinating phenomena. Understanding these inescapable rules of ecology is key to our survival and quality of life. Whether or not we heed them will have profound consequences for our future.
When Yellowstone became America’s first national park in 1872, gray wolves — which had roamed and shaped North America’s landscape for millions of years — were being massacred nationwide in a government-led extermination campaign. The eradication of these predators, who were cast as livestock-threatening villains, began soon after the Pilgrims landed in Plymouth Bay. The colonists set bounties on wolves and the war escalated in the decades to follow. As our guest once documented, wolves and their pups were shot, trapped, hunted with dogs, poisoned, dragged from dens, baited with fish hooks, set on fire, and intentionally infected with mange. One community even paved a road with wolf carcasses. In Yellowstone, the job was completed in 1926 when the last two pups in the park were killed.
The loss, brutality, and profound ecological consequences of this atrocity slowly began to sink in. Seventy years after the last Yellowstone wolves were killed, the U.S. government took unprecedented measures to reclaim what it had destroyed. In 1995 and 1996, more than thirty wolves from multiple packs were brought to the park from Canada and released in a grand experiment that would become the most successful wildlife reintroduction effort in history. Within years, more than 100 wolves in 10 packs were thriving across the 2.2 million acre park and the ecosystem was rebounding spectacularly. The roughly 100 wolves that live in the park today — which awe, inspire, and fascinate millions of visitors each year — are their descendants.
Our podcast guest, the internationally renowned wolf expert Rick McIntyre, has dedicated his life to those wolves. As a ranger naturalist, he spent more than 40 years observing wolves in America’s national parks. For the past 26 of those years, he’s observed the wolves in Yellowstone nearly every day, accumulating more than 100,000 sightings — more than any other person in history. What Rick saw unfolding through his telescope is awe-inspiring: epic adventure stories of wolf family dynasties. He watched wolves perform acts of bravery and kindness, suffer crippling injuries, conquer enemies and then treat them with benevolence, wage war over territories, form lifelong partnerships with touching loyalty, and play exuberant games of king of the castle. His work leaves no doubt that wolves are individuals with unique personalities, emotions, and complex relationships like our own. His stories have shown millions of people that these still-persecuted animals deserve our respect and need our empathy.
Since retiring from the park service in 2018, Rick has published a magnificent series of biographies of some of Yellowstone’s most noteworthy wolves. These include The Rise of Wolf 8,The Reign of Wolf 21, and his latest book, The Redemption of Wolf 302. As the writer Nate Blakeslee aptly put it: “With this third installment of Rick McIntyre’s magnum opus, the scope and ambition of the project becomes clear: nothing less than a grand serialization of the first twenty years of wolves in Yellowstone, a kind of lupine Great Expectations.”
These stories are especially important right now. Wolves desperately need federal protection from extreme and cruel wolf-killing laws recently enacted in the states of Montana and Idaho. These laws could destroy the state’s wolf populations, undoing decades of progress. In this episode, McIntyre tells the extraordinary stories some of Yellowstone’s greatest wolves, describes the wolves’ unique personalities and the pack’s dynastic dramas, and explains why science-based federal action is needed to protect these wolves, who are at risk of being massacred once again due to draconian new state laws.
As kids, we learn that if you place a shell against your ear, it becomes an auditory portal to the ocean. It’s a powerful illusion as, merged with your ear, the shell creates an echo chamber of noises that transports us to breaking waves and sea breezes, creating a moment of intimacy and wonder between us and the natural world. Much as shells have done throughout human history, as journalist Cynthia Barnett writes in her exquisite new book, The Sound of the Sea: Seashells and the Fate of the Oceans. Since the dawn of humanity, our history has been inextricably tied to the pearlescent, the ribbed, the spiraling, the speckled, and the iridescent calcium carbonate wonders and the unsung animal artists of the ocean that create, inhabit, and leave them behind.
Shells are the legacies of some of the world’s most inventive and prolific architects: mollusks. Biomineralization, the process by which these animals recycle ocean minerals into hard protective structures, evolved in microorganisms more than 500 million years ago, which eventually gave rise to the tens of thousands of known mollusk species today. These soft-bodied creatures have, quite literally, shaped the world as we know it. As Barnett writes, “We walk on a world of shell.” From limestone aquifers, to chalk, to marble, shells made by soft-bodied animals are the foundation for much of life on earth and are a blueprint for our ever-changing planet, their fossils even documenting Mount Everest’s more humble origins in the seas.
From his earliest days growing up in the piedmont forests and fields of Edgefield South Carolina, Dr. Joseph Drew Lanham dreamed of flight. As he writes in his beautiful and deeply moving memoir, The Home Place: Memoirs of a Colored Man’s Love Affair with Nature, this longing to join the aerial journeys of the blue jays that stole his grandmother’s pecans and the crows that invaded his father’s cornfield, led to Dr. Lanham’s lifelong dedication to studying birds and to exploring what it means to be a ‘rare bird’ himself: a black man in a field that is overwhelmingly white and an ecologist finding freedom through wildness on land where his ancestors were enslaved. While the cardboard wings he made as a child never achieved the skyward paths of the feathered beings he studies, his work — both academic and literary — has uplifted and inspired people around the world, and elevated and illuminated conversations about race, nature, history, freedom, and the power of birds.
In Dr. Lanham’s field of wildlife ecology, loss and hope are yoked. Since 1970, scientists estimate that three billion North American birds (nearly one in every three) have vanished — a staggering loss includes many backyard species that we have long taken for granted: sparrows, warblers, finches, blackbirds. In his research, Dr. Lanham has focused on the impacts of forestry and other human activities on the lives and disappearance of birds, butterflies, and other small forest creatures. You don’t just hear and see these animals, Dr. Lanham has said. You feel them, and when they’re gone, their absence is akin to the absence of a lover or a friend.
Lanham has written extensively about the deep and often overlooked connections between how we treat nature and how we treat our fellow humans. In 2013, he published a groundbreaking essay called “9 Rules for the Black Birdwatcher” that conveys the very real dangers that he and Black birders face–dangers brought to the national spotlight earlier this year from Christian Cooper’s assault while birding in Central Park. Racism and driving other creatures to extinction, Dr. Lanham says, are both built on the corrupt human belief that some are worthier than others. For humans and animals alike, he has said, “the fine line between life and death” is “defined by how intensely we care.”
Born in Paris to an African-American GI and a French woman at the end of World War II, Dr. Daniel Pauly rose from a difficult and extraordinarily unusual childhood in Europe to become one of the most daring, productive, and influential fisheries scientists in the history of the field — and the first to illuminate the global extent and significance of overfishing. He did this by, as he quoted from Matt Damon’s character in The Martian, “sciencing the shit out of it.”
A professor and principal investigator of the Sea Around Us Project at the University of British Columbia, Dr. Pauly has devoted his career to studying and documenting the impact of fisheries on marine ecosystems and advocating for cutting-edge policies to address it. The software, scientific tools, and methods he and his research team developed have transformed understanding of how humans are impacting oceans. His research makes very clear that fish are in global peril — and so, in turn, are we.
If our species manages to reverse course and avoid the “watery horror show,” as he calls it, for which we’re on track, it will be thanks in large part to his and his colleagues’ vision, courage, and decades of tireless work. In this episode, we speak with Dr. Pauly about the “toxic triad” that characterizes modern fisheries (catches are underreported, science is ignored, and the environment is blamed when fish populations collapse as a result), how “shifting baseline syndrome” — a term he coined — results in slow and inadequate responses to overfishing and climate change, why fish are shrinking and struggling to breathe as oceans warm, and why we need to end high seas fishing and government subsidies of international fishing fleets.
In 2017, seven Indigenous Nations and groups in Eastern Canada came together to sign an historic agreement to save a herd of caribou that had sustained all of them for time immemorial. The region’s caribou herd was once the world’s largest with 800,000 individuals. For thousands of years, indigenous peoples and the caribou met in this region. But then the herd began disappearing. By 2018, there were only 5,500 caribou left in the herd – a 99 percent decrease from 20 years before. Canada’s governments weren’t taking action, so these Indigenous Nations stepped in to save the herd. Overcoming long-entrenched divisions, and united by their common relationship to the caribou, these Nations created a groundbreaking framework for sustainably managing the herd and stopping its decline.
That agreement, known as the Ungava Peninsula Caribou Aboriginal Roundtable, or UPCART, is just one of many examples of how Indigenous Peoples across Canada are leading the way on protecting some of the world’s most ecologically important ecosystems and treasured wildlife. For millennia, Indigenous Peoples have been the caretakers of the land and have relied on animals–caribou, marten, goose, and the abundance of other animals that call Canada home. But industrial development, such as logging and mining, is putting much of the country’s wildlife and wild places at risk–along with the ways of life that depend on them. While Canada’s provinces drag their feet on needed protections, Indigenous Nations are combining Indigenous knowledge, western science, and thoughtful strategy to chart a new path for their people and for the rest of the world.
A few weeks before Charlotte’s Web was to be published, author E.B. White’s editor asked him to explain why he wrote the book about a livestock pig, Wilbur, who becomes friends with a heroic spider named Charlotte. In the now beloved novel, Charlotte saves Wilbur from slaughter by weaving messages — “SOME PIG,” “RADIANT,” “TERRIFIC,” and “HUMBLE” — into her web in the doorway of Wilbur’s stall. In doing so, she draws attention to Wilbur as an individual pig full of personality, and ensures that Wilbur is saved and cherished thereafter.
In response to his publisher’s request for explanation, White wrote: “A farm is a peculiar problem for a man who likes animals, because the fate of most livestock is that they are murdered by their benefactors. I have kept several pigs, starting them in spring as weanlings and carrying trays to them all through summer and fall. Day by day I became better acquainted with my pig, and he with me, and the fact that the whole adventure pointed toward an eventual piece of double-dealing on my part lent an eerie quality to the thing. I do not like to betray a person or a creature, and I tend to agree … that in these times the duty of a man, above all else, is to be reliable. Anyway, the theme of “Charlotte’s Web” is that a pig shall be saved, and I have an idea that somewhere deep inside me there was a wish to that effect.”
That wish is also deep inside our guest today. For over 30 years, Gene Baur has been a heroic, real-life, highly strategic, two-legged “Charlotte” for thousands of farm animals, changing millions of hearts and minds about animals and food. Baur is the co-founder and president of Farm Sanctuary, one of the nation’s largest animal rescue organizations that provides refuge for animals who had been abused, confined, and commodified as part of the U.S. factory farm system. Compared to Farm Sanctuary’s rescues, Wilbur lived a great life. White published Charlotte’s Web in 1952, just as factory farming was being invented and a decade before it began to rapidly spread – first with poultry, then pigs and cows. Today, 99% of U.S. farm animals spend their lives in large-scale industrial animal factories. Baur has made it his life’s work to try to change this.
