My Three Favourite Reads in 2025

As with previous years, Shepherd invited me to post my three favourite reads of 2025. These aren’t necessarily books published in 2025; just books I read in that year. Each time I do this, I find that, without conscious intent, my favourites fall under a general theme that have touched me that year. Past favourite reads included Feminist Eco-Fiction in 2023 and Cautionary Eco-Fiction in 2024.

2025 yielded a non-fiction book theme; books that touch on humanity’s understanding—or lack of understanding—of our fragile environment and the importance of humility and collaboration to our survival on a changing planet. Here are my three favourites:

Treeline (St. Martin’s Press, 2022) by Ben Rawlence

This book made me think. It made me cry. It made me despair. It also gave me hope. I was gripped by Rawlence’s honest and unflinching exploration on the moving treeline with climate change and what it will mean for humanity. Rawlence describes the forests of the world as the ‘heartbeat of the planet,’ the cycles of breathing and the pulses of life from the spike of oxygen in the spring when trees put out their leaves to the peaks and troughs over day and night that regulate plant photosynthesis and respiration. Their breaths are getting shallower, he writes. With more carbon dioxide in the air the trees inhale less and exhale less oxygen.

Beautifully written and rigorously reported, Rawlence invited me on a journey of the major treelines over the globe from Scotland, Norway and Russia, to Alaska, Canada and Greenland. Throughout his description of a warming world and a vanishing way of life, Rawlence meditates on the many repercussions on how humans live. There is warning. And there is optimism. This is an important book.

The Mushroom at the End of the World (Princeton University Press, 2021) by Anna Lowenhaupt Tsing

Tsing’s colourful narrative drew me into a metaphoric study of humanity’s journey through the ecology and commerce of the rare Matsutake mushroom. Both treatise on industrial capitalism and parable of survival and renewal under post-capitalist ruin, Tsing’s brilliant storytelling uses the matsutake mushroom and its industry to explore our ecological crisis: how it came about, what drives its continuation and what the consequences may look like.

The matsutake mushroom is considered a weed, growing in human-disturbed forests in the Northern Hemisphere; yet it is prized for its gourmet value. Tsing’s investigation of this rare sought-after mushroom, serves as an excellent metaphor for the study of a post-industrialist world and the promise of life after ruin. Tsing draws together a web of interconnected human and natural ecologies—from the foragers in Oregon and the Hmong jungle fighters to the capitalist traders and Japanese gourmets—to tell a fascinating tale of intrigue, greed, and violence. Laced throughout the story, are her personal reflections on the possibilities of collaborative survival of human and nonhuman.

The book is simply brilliant. The writing riveting. The story important. 

The Invention of Nature: Alexander von Humboldt’s New World (Vintage, 2016) by Andrea Wulf

I was riveted by this fascinating and illuminating biography of a visionary German naturalist and polymath—mostly forgotten—brought back to life through vivid narrative and seamless research to interesting detail. Wulf’s storytelling style drew me into this man’s incredible life, a planetologist way ahead of his time, who predicted human-induced climate change, and formulated a radical concept of nature as both a complex and intertwined global entity—long before Lovelock and Margulis came up with the Gaia Hypothesis in the 1960s.

Humboldt was the first ecologist, practicing the science of ecology for fifty years by the time German scientist Ernst Haeckel created a name for it (ökologie) in 1869. Humboldt embraced Schelling’s naturphilosophie, which espoused an organic and dynamic worldview as an alternative to the atomist and mechanist outlook that prevailed at the time. He saw nature as a living organism, animated by dynamic forces. True to his holistic vision, Humboldt invented global temperature isopleths—still used today. It is no surprise that the world’s first ecologist would also predict humanity’s devastating effect on global climate.

I found Wulf’s biography of von Humboldt fascinating, surprising, often sad, and poignant. What struck me the most was how von Humboldt’s discoveries and predictions were lost to the world with devastating effect. He made the connection and warned of human-induced climate change 200 years ago. If civilization had only heeded his warning!

Water Is… The Meaning of Water (Pixl Press, 2016) by Nina Munteanu

My own non-fiction book Water Is…The Meaning of Water—a celebration of water in all its facets—is offered here as fitting this theme of celebrating Nature and educating us on how to live more lightly and responsibly. Here’s what the publisher’s blurb says:

Internationally published author, teacher and limnologist Nina Munteanu explores one of the most important substances of Earth. Nina Munteanu’s Water Is… The Meaning of Water represents the culmination of over twenty-five years of dedication as limnologist and aquatic ecologist in the study of water. As a research scientist and environmental consultant, Nina studied water’s role in energizing and maintaining the biomes, ecosystems, and communities of our precious planet. During her consulting career for industry and government, Nina discovered a great disparity between humanity’s use, appreciation and understanding of water. This set in motion a quest to further explore our most incredible yet largely misunderstood and undervalued substance. Part history, part science and part philosophy and spirituality, Water Is… combines personal journey with scientific discovery that explores water’s many “identities” and ultimately our own.

Water Is… was chosen by Margaret Atwood that year as one of her favourites in The New York Times ‘Year in Reading.’

Nina Munteanu is an award-winning novelist and short story writer of eco-fiction, science fiction and fantasy. She also has three writing guides out: The Fiction WriterThe Journal Writer; and The Ecology of Writing and teaches fiction writing and technical writing at university and online. Check the Publications page on this site for a summary of what she has out there. Nina teaches writing at the University of Toronto and has been coaching fiction and non-fiction authors for over 20 years. You can find Nina’s short podcasts on writing on YouTube.

Wonder and Reason in The Age of Water

Writer and essayist Annis Pratt begins her compelling essay “World of Wonder, World of Reason” in Impakter, with the question: “Do we live in a world of wonder where Nature ultimately calls the shots or a world of reason where Homo Sapiens are in control?”

Invoking the now vogue term “Anthropocene”, she puts it another way: “Is Nature dependent upon our definitions of it, or does it both precede and transcend human consciousness?  Does the term “Anthropocene” signal an apocalyptic shift that places us at the center of the Universe and if so, is the death of Nature upon us, or are we mistaken?”

Pratt examined and synthesized four works of different perspectives on nature and humanity to answer these questions. My book “Water Is…” was among them:

  1. The Invention of Nature: Alexander von Humboldt’s New World” by Andrea Wulf (Knoff, 2015)
  2. The Hidden Life of Trees: What They Feel, How They Communicate” by Peter Wohlleben, translated by Jane Billinghurst (Greystone Books, 2016)
  3. Water Is…The Meaning of Water” by Nina Munteanu (Pixl Press, 2016)
  4. Sapiens: A Brief History of Humankind” by Yuval Noah Harari (Harper Collins, 2015)

The first three, says Pratt, are scientists who made close observations of nature that filled them with wonder at the complexity of its processes: “Alexander von Humboldt, an 18th century Prussian scientist, the father of ecology; Peter Wohlleben, an ecologist who worked over twenty years for the forestry commission in Germany and Nina Munteanu, a limnologist, university teacher and award-winning ecologist.” The fourth, an Israeli historian, Yuval Noah Harari took a dramatically different stance, says Pratt. “He deplores our epoch when human egos have run amuck, putting Nature itself in peril.”

Wonder: Alexander von Humboldt

AlexVonHumboldt

Alexander von Humboldt lived from 1769-1859 (when Darwin published Origin of Species) and considered a genius, polymath, explorer and keen observer of botanical phenomena. In a world and time when Enlightenment thinkers and scientists predicated their observations on a premise of a static unchanging Nature (recall this was prior to Darwin’s controversial theory of evolution), von Humboldt discovered that nature’s one constant was change. As with von Goethe and von Schelling, von Humboldt embraced Naturphilosophie to comprehend nature in its totality and to outline its general theoretical structure. Naturphilosophie espoused an organic and dynamic worldview as an alternative to the atomist and mechanist outlook prevailing at the time.

Von Humboldt succeeded in proving that species change according to their circumstances, such as altitude or climate. According to Wulf, Bildungsreich was a force that shaped the formation of bodies, with every living organism, from humans to mould, having this formative drive. Von Humboldt’s “discovery that natural phenomena are inter-influencing elements of an interdependent whole, connected and interacting along an ‘invisible web of life,’ made Humboldt the first ecologist,” writes Pratt.

Wonder: Peter Wohlleben

Wohlleben

“Contemporary German forest ranger Peter Wohlleben belongs to the same school of Naturalphilosophie as Humboldt, bringing a similar sense of curiosity and wonder to his botanical observations,” says Pratt, who suggests that criticism aimed at his work arose in response to the anthropomorphic “voice” he uses—despite validation through the work of Dr. Suzanne Simard, Professor of Forest Ecology at the University of British Columbia.

Simard showed that trees “talk” to each other through electrical impulses as part of an underground network of fungi: “like fiber-optic internet cables.”

Pratt describes the events that led to Wohlleben’s path as an ecologist and his series of “hidden life of” books: he had become uncomfortable chopping down trees and spraying the forest with chemicals and became depressed when his superiors refused to consider his alternative methods. Wohlleben had decided to quit his job and emigrate to Sweden, when the town of Hummel decided to annul its state contract, reconstitute itself as a private preserve, and hire him to implement his innovations.

Wohlleben uses the findings of Simard and other scientists that trees communicate, nourish and heal each other. “It appears that the nutrient exchange and helping neighbors in times of need is the rule, and this leads to the conclusion that forests are superorganisms with interconnections much like ant colonies,” writes Wohlleben.

Wonder: Nina Munteanu

NinaWaterIs-Impakter

“In the same way that Peter Wohlleben approaches the hidden life of trees with a combination of scientific observation and enthusiastic wonder, in Water Is…The Meaning of Water,  Canadian limnologist Nina Munteanu observes the hidden properties of water with a scientist’s eye for detailed processes and a sense of amazement at their intricacies,” writes Pratt. “Echoing Humboldt’s discovery of the interwoven multiplicities of nature, [Munteanu] “transcends ‘Newtonian Physics and Cartesian reductionism aimed at dominating and controlling Nature’”:

“Science is beginning to understand that coherence, which exists on all levels—cellular, molecular, atomic and organic—governs all life processes. Life and all that informs it is a gestalt process. The flow of information is fractal and multidirectional, forming a complex network of paths created by resonance interactions in a self-organizing framework. It’s stable chaos. And water drives the process”—Nina Munteanu, Water Is…

“In addition to providing a gripping analysis of water science,” says Pratt, Nina Munteanu’s Water Is… “provides an encyclopedic trove of quirky observations, like how Galileo understood water flow, the Chinese character for water, Leonardo da Vinci’s water drawings, the Gaia Hypothesis, and David Bohm’s theory of flux.”

“the Gaia Hypothesis proposes that living and non-living parts of our planet interact in a complex network like a super-organism. The hypothesis postulates that all living things exert a regulatory effect on the Earth’s environment that promotes life overall…Much of nature – if not all of it – embraces this hidden order, which I describe as ‘‘stable chaos’”—Nina Munteanu, Water Is…

Reason: Yuval Noah Harari

YuvalNoahHarari

Israeli Historian, Harari sees Homo Sapiens as destructively self-serving. “Even in our earliest history,” Pratt tells us, “he suspects we were responsible for the extirpation of the Neanderthals. Everywhere we settled, mammoths and other megafauna suffered mass extinction. “The historical record,” he concludes, “makes Homo Sapiens look like an ecological serial killer.”

We are like the bully elbowing his way at school. And our casualties—such as the extinction of a dozen species a day—are innocence lost.

According to Harari, while the industrial revolution “liberated humankind from dependence on the surrounding ecosystem,” it provided no lasting benefit to the human race: “Many are convinced that science and technology hold the answers to all our problems…” but, “Like all other parts of our culture, it is shaped by economic, political and religious interests…We constantly wreak havoc on the surrounding ecosystem, seeking little more than our own comfort and amusement, yet never finding satisfaction.”

Human-Centred or Nature-Centred?

To answer Pratt’s first question: “Do we live in a world of wonder where Nature ultimately calls the shots or a world of reason where Homo Sapiens are in control?” she invokes global warming to suggest that we don’t have the last say in the planet’s welfare: “Aren’t these tumultuous catastrophes demonstrative of nature’s ability to rise over and against what we throw at it? Global warming may end civilization and perhaps the human species along with so many others we have destroyed, but are human beings really capable of engineering the destruction of the planet?  I doubt it.”

I concur. While humanity is capable of extensive natural destruction, Gaia will not only accommodate—it will prevail. Very soon—some think now already—Nature may no longer resemble that “friendly” and stable Holocene environment that we’ve come to rely on and exploit so heedlessly. Species will die out. Others will take their place in a shifting world.

As the first swell of the climate change tidal wave laps at our feet, we are beginning to see the planetary results of what humanity has helped create and exacerbate. Humanity has in many ways reached a planetary tipping point; a threshold that will be felt by all aspects of our planet—both animate and inanimate—as the planet’s very identity shifts.

One thing is certain: environments will cease to be hospitable for humanity. Compared with many other life forms, we actually have very narrow tolerances to stay healthy and survive:

  1. We need lots of water (70%)
  2. We freeze or cook beyond the 40-100 degree F range in a galaxy that goes from minus 400 at the moon’s south pole to 25 million degrees inside the sun
  3. We faint from lack of oxygen on our tallest mountains
  4. We need a pH balance of 6.5 to 7.5 to stay alive
  5. Ionizing radiation kills us at low concentrations
  6. Many compounds in the wrong amounts are toxic to us

But something will benefit. For every perturbation imposed there is adaptation and exploitation, stitched into the flowing tapestry of evolution. That is ecology.

Ecology studies relationships and change in our environment: how we interact, impact one another, change one another. Ecology studies individuals, communities and ecosystems and provides insight into the dynamics that cause and result from these interactions.

Diary Water cover finalIn my upcoming novel “A Diary in the Age of Water” (due in May 2020) a journaling limnologist in the near-future reflects on the acidified oceans in her current world: flagellates (microscopic plankton with flagella) have outcompeted diatoms (food for many species) and are mainstay of the box jellyfish—the top marine predator from the Proterozoic Era—that has overrun the entire ocean. The box jellyfish is currently overrunning Tokyo Bay. The story proceeds into the future when dead zones—currently found in the Gulf of Mexico, the mouth of the Mississippi River, Chesapeake Bay, Kattegat Strait, and Baltic Sea—occur on virtually every marine and freshwater coast; the AMOC eventually fails and the oceans grow toxic; sea level immerses Florida, the Pudong District, the entire Maldives, and dozens of coastal cities; and global temperature has triggered a heat-related epidemic involving heat shock proteins. This is a world very different from the one we have grown accustomed to; it is a harsh, hostile world that no longer treats us well; but it is a world, none the less.

Living with Natural Succession

One of the first things we learn in Ecology 101 is that change is the one constant in biology; systems endure by striking dynamic equilibria within a shifting tapestry. Succession—the natural procession of one community to another—lies at the core of a dynamic and functional ecosystem, itself evolving to another system through succession.

“Still immature and undeveloped, an oligotrophic lake often displays a rugged untamed beauty. An oligotrophic lake hungers for the stuff of life. Sediments from incoming rivers slowly feed it with dissolved nutrients and particulate organic matter. Detritus and associated microbes slowly seed the lake. Phytoplankton eventually flourish, food for zooplankton and fish. The shores then gradually slide and fill, as does the very bottom. Deltas form and macrophytes colonize the shallows. Birds bring in more creatures. And so on. As Nature tames the unruly lake over time, one thing replaces another. As a lake undergoes its natural succession from oligotrophic to highly productive eutrophic lake, its beauty mellows and it surrenders to the complexities of destiny. Minimalism yields to a baroque richness that, in turn, heralds extinction. The lake shrinks to a swamp then buries itself under a meadow.”—Nina Munteanu A Diary in the Age of Water

Ecology and Story

NaturalSelection-front-webIn a talk I give at conferences on “Ecology and Story”, I provide examples of extremophiles that have adapted to and thrive in extreme conditions on Earth.  The brine shrimp of Mono Lake—an endorheic lake that is extremely salty, anaerobic and alkaline—happily hatch in the trillions every year. The bacteria of Rio Tinto—toxic with heavy metals—thrive on the iron through a biofilm that protects them. Radiotrophic fungi feed on gamma radiation at the Chernobyl nuclear power plant. Life on Earth will endure and prevail—not despite but alongside humanity’s imposed ecological succession.

The question is, will we survive our own succession?

Literature of the Anthropocene

Memory of waterTerms such as eco-fiction, climate fiction and its odd cousin “cli-fi”, have embedded themselves in science fiction and literary fiction terminology; this fiction has attracted a host of impressive authors who write to its calling: Margaret Atwood, Emmi Itäranta, Jeff VanderMeer, Richard Powers, Barbara Kingsolver, Upton Sinclair, Ursula Le Guin, JoeAnn Hart, Frank Herbert, John Yunker, Kim Stanley Robinson, James Bradley, Paolo Bacigalupi, Nathaniel Rich, David Mitchell, Junot Diaz, Claire Vaye Watkins, J.G. Ballard, Marcel Theroux, Thomas Wharton—just to name a few. The list is growing. Of course, I’m on it too. Many of these works explore and illuminate environmental degradation and ecosystem collapse at the hands of humanity.
