In the passage below of my eco-fiction dystopian novel A Diary in the Age of Water, the year is 2065 and the diarist Lynna (a limnologist at the University of Toronto) reflects on the steeply growing infertility in humans and our tenuous future. Lynna draws on the factual study published close to fifty years earlier (in 2017) by Hagai Levine and others at the Hebrew University of Jerusalem, who found that sperm counts among western men had reduced close to 60% in four decades:
Back in ’49, Daniel and I had several discussions about the environmental triggers and epigenetic mechanisms of infertility in humans. Daniel went on about how it was all about the men. While women showed signs of increased infertility, men’s rate of infertility was more than double that of the women, he said. Taking an inappropriately gleeful tone, Daniel cited the classic 2017 paper by the Hebrew University of Jerusalem, the one that started it all. Their findings were startling: men’s sperm count in North America, Europe, Australia, and New Zealand had diminished by sixty percent in forty years, between 1973 and 2011. The scientists predicted that by 2060, virtually all men in these parts of the world would have little to no reproductive capacity.
It’s 2065 and they’re right. Only it’s worse. Before the twenties, only the developed countries seemed to be affected, but then sperm counts started to plummet in South American countries, like Argentina and Brazil, where GMO, pesticides, and solvent manufacturing were exploding.
You get out what you put into the ground. India and Asia—where endocrine-disruptive chemicals are finding their way into the water—are reporting very low sperm counts in their men as well as higher incidents of intersex humans.
You get out what you put into the water. We are over two thirds water, after all. I find it a little ironic that we’ve inadvertently produced a non-discriminatory way to control the problem of humanity’s overpopulation. Infertility. And that infertility results from defiling the environment we live in.
But now climate change is shouldering its way in. Climate change is shutting us down.
Is this the first sign of our impending extinction?
–excerpt from “A Diary in the Age of Water”

That environmental perturbations impact our ability to reproduce has been proven. In their 2017 article, Levine et al. write that:
“Sperm count and other semen parameters have been plausibly associated with multiple environmental influences, including endocrine disrupting chemicals (Bloom et al., 2015; Gore et al., 2015), pesticides (Chiu et al., 2016), heat (Zhang et al., 2015) and lifestyle factors, including diet (Afeiche et al., 2013; Jensen et al., 2013), stress (Gollenberg et al., 2010; Nordkap et al., 2016), smoking (Sharma et al., 2016) and BMI (Sermondade et al., 2013; Eisenberg et al., 2014a). Therefore, sperm count may sensitively reflect the impacts of the modern environment on male health throughout the life course (Nordkap et al., 2012).”

Thanks to chemical companies such as DuPont and others, forever chemicalsare currently in rain water globally, and in many places in unhealthy concentrations. These endocrine-disrupting and cancer-causing chemicals often end up in drinking water and include PCBs, phthalates, PFAS, BPAs (used in pesticides, children’s products, industrial solvents and lubricants, food storage, electronics, personal care products and cookware).

My eco-fiction book A Diary in the Age of Water was recently cited along with Paolo Bacigalupi’s book The Water Knife, in an article on conflict risk in international transboundary water bodies.
The citation was made in Ken Conca’s article (Chapter 1: “Climate change, adaptation, and the risk of conflict in international river basins: Beyond the conventional wisdom”) of the 2024 Routledge book “New Perspectives on Transboundary Water Governance:Interdisciplinary Approaches and Global Case Studies” (edited by Luis Paulo Batista da Silva, Wagner Costa Ribeiro, and Isabela Battistello Espíndola).
Conca begins his chapter with a statistic—an estimated 310 rivers in the world cross national borders, form borders, or both—and goes on to discuss the risk of conflict that naturally arises in such situations. Conca traces a rich history of disputes, with one of the oldest occurring between Lagash and Umma (present-day southern Iraq) in 2500 BCE. Conca explores the early warning indicators explored by the World Resources Institute that imply “a future in which our bordered politics, combined with hydrologic interdependencies, could yield a combustible mix of tension and grievances” and adds that several rivers flagged in the WRI study lie in regions of crhonic tension and political instability. He then includes a 2013 quote by former UN Secretary-General Ban Ki-moon:
“Our experiences tell us that environmental stress, due to lack of water, may lead to conflict, and would be greater in poor nations … population growth will make the problem worse. So will climate change. As the global economy grows, so will its thirst. Many more conflicts lie just over the horizon.” Ban also stated that climate change promised “an unholy brew that can create dangerous security vacuums” in which “mega-crises may well become the new normal.”
Conca makes his point by quoting the U.S. Center for Strategic and International Studies: “the real wild card for political and social unrest in the Middle East over the next 20 years is not war, terrorism, or revolution—it is water.”
Conca makes the connection with narratives of fiction:
“This framing of scarcity-induced conflict risk has even crept into the world of fiction. Paulo Bacigalupi’s dystopian novel The Water Knife (2016) portrays a parched southwestern United States of the near future. He foresees American states militarizing both their water relations (with corporate militias destroying infrastructure meant to divert water) and their borders (with the water-rich states seeking to keep thirsty migrant out, and the water poor states seeking to keep them in). Nina Munteanu’s A Diary in the Age of Water (2020) envisions Canada as a wholly-owned colony of the United States (itself owned by China). She describes a world in which Niagara Falls has been turned off and pet ownership is outlawed as an unacceptable water burden.”
Conca unpacks various misconceptions on sources of conflict and conflict resolution to do with transboundary water bodies. The chapter is very enlightening, as is the entire book!
The 2024 Routledge book “New Perspectives on Transboundary Water Governance:Interdisciplinary Approaches and Global Case Studies” (edited by Luis Paulo Batista da Silva, Wagner Costa Ribeiro, and Isabela Battistello Espíndola) is described by the publisher below:
This book presents a novel examination of transboundary water governance, drawing on global case studies and applying new theoretical approaches.
Excessive consumption and degradation of natural resources can either heighten the risks of conflicts or encourage cooperation within and among countries, and this is particularly pertinent to the governance of water. This book fills a lacuna by providing an interdisciplinary examination of transboundary water governance, presenting a range of novel and emerging theoretical approaches. Acknowledging that issues vary across different regions, the book provides a global view from South and Central America, Africa, Asia, and the Middle East, with the case studies offering civil society and public managers concrete situations that indicate difficulties and successes in water sharing between bordering countries. The volume highlights the links between natural resources, political geography, international politics, and development, with chapters delving into the role of paradiplomacy, the challenges of climate change adaptation, and the interconnections between aquifers and international development. With rising demand for water in the face of climate change, this book aims to stimulate further theoretical, conceptual, and methodological debate in the field of transboundary water governance to ensure peaceful and fair access to shared water resources.
This book will be of interest to students and scholars of water resource governance from a wide variety of disciplines, including geography, international relations, global development, and law. It will also be of interest to professionals and policymakers working on natural resource governance and international cooperation.

People reading “Water Is…”in Vancouver and Toronto
Margaret McCaffery, chair of the PROBUS Toronto Speakers Committee invited me some time ago to speak to their club in June of 2024 on my experience with water: as scientist, mother, and environmentalist. The audience was mostly retired professional and business people with enquiring minds. I gave my Powerpoint talk in the Holy Rosary Parish Hall on St. Clair West and then enjoyed a vigorous session of challenging and interesting questions to which I responded with equal vigour.
Here is the blurb for the presentation:
Canadian limnologist Nina Munteanu explores the many dimensions of water through her journey with water as mother, educator, and scientist. She describes an emotional connection with nature that compels us to take care of our environment with love versus a sense of duty.
Nina’s talk draws on her book Water Is… The Meaning of Water, part history, part science and part philosophy and spirituality. The book examines water’s many anomalous properties and what these meant to us. In sharing her personal journey with this mysterious elixir, Nina explores water’s many ‘identities’ and, ultimately, our own. Water Is… was Margaret Atwood’s first choice in the 2016 New York Times ‘Year in Reading.’ Water is… will be available for sale at the talk.
I started with my story as a child, growing up in the Eastern Townships of Canada
I defined “limnology” and talked about my career as a limnologistand environmental consultant
I discussed some of water’s anomalous properties, all life-giving
I brought in some interesting things about water…
I tied my journey with water to family and friends and my watershed
I ended my talk with a discussion of the Watermark Project to catalogue significant stories to water bodies all over the world
I also brought my latest eco-clifi novel A Diary in the Age of Water for sale. It interested quite a few people and generated several wonderful discussions.

No writer works alone. Sure, we may work alone when writing, but all other aspects of getting our writing out to you, the reader, involves a team of other people. Like all good things, writing is a collaborative affair. All professional writers enter a contract with their publisher to work with editors, marketers, and also with cover artists, designers and interior artists. All together create the final artistic expression shared with the reading audience.
I want to focus on the latter here and celebrate how art and design help create more than what the writer alone produces. When my writing career started in earnest in 1995 with my first publication in a professional magazine, I was involved in collaborations with artists, who all improved my work.
Arc of Time was my first short story publication, appearing in Armchair Aesthete in the Summer/Fall issue of 2002. Armchair Aesthete is a small literary magazine in the United States and features funky cover art.
Magazine cover for Ultra! and interior design for “Arc of Time”
Arc of Time was then accepted in the premiere issue of Ultra! (Aardwolf Publications) in 2004. That issue contained a fully illustrated and designed interior, which really set off the story—an epistemological exchange of emails linked with narrative. In 2013, MetaStellar Speculative Fiction and Beyond, which provides illustrations for each story it carries, used one of my own photographs to illustrate Arc of Time.
Feature cover illustration for “Arc of Time” on MetaStellar site
Virtually Yours first appeared in Hadrosaur Tales in Issue #15 in December 2002. Hadrosaur Tales is a small but vibrant literary magazine out of Las Cruces, New Mexico and featured interesting covers.
Cover and story illustrations in Nowa Fantastyka for “Virtually Yours”
Virtually Yours was republished all over the world and is up to its tenth publication this year. Several publications included artwork specifically for the story. Nowa Fantastyka, out of Poland, is a slick magazine that boasts a lot of images, colour interiors and illustrations. My story was introduced with illustrations that enhanced its impact.
Interior illustrations for “Virtually Yours” in Amazing Stories and MetaStellar, respectively
Its reprint in Amazing Stories was illustrated evocatively by Duncan Long. In the story’s later reprint in MetaStellarSpeculative Fiction and Beyond, Brigitte Werner created a beautiful illustration for the story.
Nowa Fantastyka cover art and story artfor “A Butterfly in Peking”
A Butterfly in Peking first appeared in Issue #17 of Chiaroscuro in 2003. Its reprint in the Polish magazine Nowa Fantastyka in 2005 included interior art that introduced the tone and feel of the story.
Megan Survival Anthology cover art and story artfor “Fingal’s Cave”
Fingal’s Cave was first published in The Megan Survival Anthology (Reality Skimming Press) in December 2016. The publication included art by Jeff Doten specific to each story in the anthology and I found his artwork for Fingal’s Cave wonderfully intriguing.
Artwork for “The Way of Water” in various publications
The Way of Water was first published in Future Fiction then in a smart print publication by Mincione Edizioni in Rome, Italy in May 2016. The story was reprinted several times and artwork associated with it included in some of the publications. One is Little Blue Marble, an online magazine that features artwork for each story it runs.
Cover art of Eagle Magazine and story art for “Natural Selection”
Natural Selection first came out in my short story collection of the same name in 2013. It was then reprinted in the premiere issue of Eagle Magazine and featured stellar and evocative interior illustrations by Ionuț Bănuță.
Interior story art for “Natural Selection”
Out of the Silence first appeared in Issue #85 of subTerrain Magazine in May 2020 and featured diverse and rich interior art and design (not pictured here). Its reprint in A House of Dawn in 2021 received its own artwork, which enhanced the tone and subject of the story.

I’d be remiss if I didn’t add the important artwork of artists on the covers of several of my novels and collections. As a reader, I can attest that cover art plays an important role in introducing a book to a potential reader. Whether we pick up a new author’s book to peruse depends upon the image, title and design of the cover. I have been very fortunate with my publishers and their artists.
Book covers for “Collision with Paradise” and “The Cypol”
My first published novel (Collision with Paradise) and novella (The Cypol)—both SF erotica—were designed to intrigue and titillate.
Costi Gurgu illustrated and designed the covers of my space detective thriller The Splintered Universe Trilogy for Starfire. The three books and their covers, formed a tryptic that reflected the journey of the lead character—a badass galactic detective—and her evolution.
Cover art for books of “The Splintered Universe” Trilogy
Costi Gurgu also designed the cover of my short story collection Natural Selection for Pixl Press in 2013 using an illustration by West Coast artist Anne Moody that showed the fluidity of nature.
Tikulin-illustrated covers for “Darwin’s Paradox” and “The Last Summoner”
Tomislav Tikulin illustrated the cover of my novel Darwin’s Paradox for Dragon Moon Press in 2007. The cover image ostensibly represented a work of hard science fiction and attracted much attention from SF fans. Tikulin’s evocative illustration of a knight in a drowning cathedral was then used for the cover of The LastSummoner for Starfire, with attractive typology design by Costi Gurgu. As with all of Tikulin’s work, this mysterious cover attracted the attention of many readers with many questions.
L’Ultima Evocatrice, a novella version of The Last Summoner in Italian was illustrated and designed for Delos Digital Publications in 2021 and draws the reader into the intrigue of the story.
My most recent novel, A Diary in the Age of Water, published by Inanna Publications in 2020, features elegant cover art by Val Fullard and over thirty pieces of interior art work by my own hand.
Interior art representing the diarist’s sketches in “A Diary in the Age of Water
I wasn’t sure if the publisher would agree to use my sketches, but she did, to my surprised delight. She agreed with me that the interior illustrations, which represent sketches by the scientist diarist, lend a tangible reality to the story and a further focus of interest.

The excitement never ends for me as a writer … With the newest installation to the Icaria Series imminent, Dragon Moon Press will be re-issuing Darwin’s Paradox and Angel of Chaos, along with the newest addition Gaia’s Revolution along with new covers and interiors. I can’t wait to see what Dragon Moon Press comes up with! …

Her novel “A Diary in the Age of Water” was released by Inanna Publications (Toronto) in June 2020.
I started out by reviewing what I had read in 2023. It looked like I’d read about thirty odd books, almost half and half non-fiction to fiction. That’s not many, but I’m a slow reader. I pore through each book at a snail’s pace, spending time making notes with some, particularly the non-fiction books, which I use to research my writing. With fiction, I dive in deep and thoroughly savor each word and sentence like a mouthful of an excellent meal made with loving hands. Books varied from non-fiction scholarly works on forest ecosystems (The Treeline by Ben Rawlence) and post-capitalism (Four Futures by Peter Frase) to literary fiction, political thrillers, speculative fiction, clifi, and eco-fiction.
It was a tough choice, but I came up with three choices and a thematic rationale that resonated with me and made a deep kind of sense for that year: all three books were eco-fiction of sorts and featured hopeful stories of strong women, acting out of compassion and in solidarity with intelligence, kindness and courage. For me, 2023 was a year of strong feminine energy for the planet and my favourite books reflect that. Here they are (read the original article on Shepherd here):
The first of my favourite three books of 2023 is Michelle Min Sterling’s Camp Zero.
Set in the remote Canadian north—a place I love for its harsh beauty—this feminist climate fiction explores a warming climate through the perilous journeys of several female characters, each relating to her environment in different ways. Each woman exerts agency in surprising ways that include love, bravery and shared community. The strength of female power carried me through the pages like a braided river heading to a singular ocean. These very different women journey through the dark ruins of violent capitalism, colonialism and patriarchy—flowing past and through hubristic men pushing north with agendas and jingoistic visions—to triumph in an ocean of solidarity. I empathized with each woman as she found her strength and learned to wield true heroism—one based on collaboration and humble honesty.
My second favourite book of 2023 is Yevgeni Zamyatin’s We.
I enjoyed this 1920 hopeful dystopia for its courageous and unprecedented feminism. While the story centres on logical D-503, a man vacuously content as a number in the One State, it is I-330—Zamyatin’s unruly heroine—who stole my attention. Confident, powerful and heroic, the liberated I-330 embraces the Green Wind of change to influence D-503. A force of hope and resilience, she braves torture to successfully orchestrate a revolution that breaches the Green Wall—feats typically relegated to a male protagonist in novels of that era. When pregnant O-90 refuses to surrender her child to the State, I-330 helps her escape to the outside, where the Green Wind of freedom blows. I resonated with Zamyatin’s cautionary tale on the folly of logic without love and Nature.
My third favourite book of 2023 is Hugh Howie’s Wool (first of the SILO series).
Juliette—humble and gutsy, kind and relentlessly motivated in her journey for the truth—kept the pages turning for me. Juliette is a mechanic from the Down-Deep of the underground Silo, humanity’s last refuge to a toxic world. When Juliette inexplicably lands the job of sheriff, she treats her new position as a tool to seek the truth about her lover’s mysterious recent death. At her own peril, she pulls on threads that ultimately reveal a great conspiracy.
Juliette’s literal and metaphoric rise from the Down-Deep to the Up-Top is a feminist’s journey that transcends intersectional barriers as she battles small-minded men of power and maintains her integrity by refusing to abide by the inhumane Up-Top rules of order. By the end, I sensed a victory for humankind through womankind.
You might be interested in two of my own eco-fiction novels that feature several strong female protagonists:
Darwin’s Paradox follows the complex dynamic of a brave mother and her willful teenage daughter, both ‘gifted’ by a virus living inside them. Accused of murder and deliberately spreading the virus that killed many, Julie fled the enclosed city and settled in the climate wastelands with her husband and their child. Years later, when their harsh refuge is threatened by city forces seeking mother and daughter for experimentation, Julie leaves her family and gives herself up to the city, hoping they will abandon pursuing her daughter. Still psychically connected to the city’s AI community (now evolving into an autonomous entity with the intelligent virus), Julie entangles with political intrigue while her daughter, who followed her to the city, stumbles into her mother’s violent past.
A Diary in the Age of Waterfollows the climate-induced journey of Earth and humanity through four generations of women, each with a unique relationship to water. Centuries from now, in a dying boreal forest in what used to be northern Canada, Kyo, a young acolyte called to service in the Exodus, yearns for Earth’s past—the Age of Water—before the “Water Twins” destroyed humanity. Looking for answers and plagued by vivid dreams of this holocaust, Kyo discovers the diary of Lynna, a limnologist from that time of severe water scarcity just prior to the destruction. In her work for a global giant that controls Earth’s water, Lynna witnesses and records in her diary the disturbing events that will soon lead to humanity’s demise.

I recently returned to southern Ontario from a novel-research trip to the Arctic, where I hope next time to see the incredible northern lights (this recent visit was during their midnight sun period; so, no luck with northern lights). But, in the future I may not have to travel north to see them…
My eco-novel A Diary in the Age of Water begins sometime in the future with Kyo, a blue multi-armed being, living in the dying boreal forest of post-apocalypse Canada; Kyo finds a diary by Lynna Dresden, a limnologist from the calamitous time when climate change ravaged the planet and when the Water Twins destroyed humanity. Yearning for clarity about that holocaust, Kyo reads the diary.
Lynna begins her February 24, 2057 diary entry with a definition of the Aurora Borealis:
“Also called northern lights, this is a natural electrical phenomenon caused by the interaction of electrically charged particles from the sun with the upper atmosphere near the north magnetic pole. It is characterized by the appearance of bands of reddish, greenish, and other coloured lights in the sky that follow the magnetic lines of force. The colours differ based on the type of gas particles that are colliding. The most common colour—a pale yellowish-green—comes from oxygen molecules some sixty miles above the earth. All-red auroras are rare and are associated with high-altitude oxygen, up to two hundred miles high. Nitrogen produces blue or purplish-red aurora.”
A Diary in the Age of Water
Lynna lives with her daughter Hilde in now warm Toronto, in southern Canada, where the northern lights had been up to recently only rarely observed. By 2057, this has changed:
Last night after supper, Hilde and I went for a walk along Shaw to Christie Pits, where I used to play as a kid. She wanted to show me the magnificent aurora borealis that had been streaming dramatically for the past several weeks. When I was a kid, auroras this far south were unheard of. Now they are common. The night sky was clear, and we enjoyed the fresh spring air as we ambled down Shaw Street. We parked ourselves on the damp grass among other spectators of the colourful night sky and watched the dancing light show. It was mesmerizing: ribbons of mostly green and pink light rippled as if tugged by a mischievous wind. They danced with a kind of life that brought me back to my childhood.
Northern lights happen when the magnetic field of our planet is disturbed by the solar wind. As the particles slide along the contours of the Earth’s magnetosphere, they glow as they lose their energy. The particles energize the air molecules enough to make them glow in various colours, depending on the composition of the gases.
Earth’s magnetic field is generated and maintained by an ocean of superheated, swirling metal around a solid iron core. These act like a dynamo to create electrical currents, which, in turn, create our magnetic field. But our magnetic field is weakening, and a flip is imminent. In the past two hundred years, the field has weakened by fifteen percent. That’s why we’re seeing these auroras in Toronto. A weaker field creates more auroras. They’ve become common here, particularly during the winter and spring months. NASA predicts that the field could be gone in five hundred years or less and then take another two hundred years to rebuild.
The field will first become more complex and might show more than two magnetic poles—playing havoc with our navigation systems and God knows what else—until it is entirely gone. Then it will presumably build and align in the opposite direction. When the magnetic field goes, so will our shield against radiation. First, the ozone layer—our shield against ultraviolet rays—will be stripped away, and then the atmosphere may lose other key elements and grow thinner. Will we end up like Mars 4.2 billion years ago, when severe solar storms stole its very atmosphere and evaporated all its water?
Mars once had a strong magnetic field like Earth. But then Mars cooled and its conducting geodynamo stopped rotating. In the absence of the protective field, the solar wind surged in and excited the ions in the upper Martian atmosphere to an escape velocity. The solar wind just swept the air away. The surface pressure of the Martian atmosphere dwindled from one thousand millibars to six millibars. Mars lost about the same atmosphere that Earth has today.
Mars is our destiny; it’s just a question of when. We’re all batteries, running dry. I considered this probable fate for Earth as we watched the exquisite example of our changing magnetic field. But I didn’t share it with Hilde, who watched with her mouth open in rapt wonder. If she’s lucky, she will experience no more of this progression than these amazing auroras. The weakening magnetic field and the associated loss of protection and atmosphere won’t happen for a while. I hope.
I shared none of my thoughts with Hilde.

How Auroras Work
The Aurora Borealis is named after the Roman goddess of the dawn, Aurora, and the Greek name for north wind, Boreas. According to scientists, the colorful and eerie streams of light known as the Aurora Borealis result from “magnetic ropes” that link the Earth’s upper atmosphere to the sun. Solar winds surf them, providing energy for geomagnetic storms and auroras. NASA researchers describe the “ropes” as “a twisted bundle of magnetic fields organized much like the twisted hemp of a mariner’s rope.”
The earth is constantly immersed in the solar wind, a rarefied flow of hot plasma emitted by the sun in all directions. Auroras happen when charged particles from the magnetosphere collide with atoms and molecules of the Earth’s upper atmosphere (at altitudes above 80 km). Most of these particles originate from the sun and arrive in a relatively low-energy solar wind. When the trapped magnetic field of the solar wind is favourably oriented (mostly southwards) it reconnects with the earth’s magnetic field and solar particles then enter the magnetosphere and are swept to the magnetotail. Further magnetic reconnection accelerates the particles towards earth.
Earth’s magnetosphere (image by Wikipedia)
These atmospheric collisions electronically excite atoms and molecules in the upper atmosphere. The excitation energy can be lost by light emission or collisions. Most auroras are green and red emissions from atomic oxygen. Molecular nitrogen and nitrogen ions produce some low level red and very high blue/violet auroras. Typically, an aurora appears either as a diffuse glow or as “curtains” that extend more or less in an east-west direction. Each curtain is made of many parallel rays, each lined up with the local direction of the magnetic field lines, suggesting that aurora are shaped by the earth’s magnetic field.
The earth’s magnetosphere is the space region dominated by its magnetic field. It forms an obstacle in the path of the solar wind, causing it to be diverted around. When the solar wind is “perturbed”, it transfers energy and material into the magnetosphere. The electrons and ions in the magnetosphere that become energized move along the magnetic field lines to the polar regions of the atmosphere.
Auroras have been observed on Jupiter, Saturn, Venus, Mars, Uranus and Neptune. The auroras on the gas giants appear to be powered by the solar wind. In addition, Jupiter’s moons, especially Io, are powerful sources of auroras. These come from electric currents along field lines, generated by a dynamo mechanism due to the relative motion between the rotating planet and the moving moon. Io, which experiences active volcanism and has an ionosphere, is a particularly strong source, and its currents also generate radio emissions.
The passage from A Diary in the Age of Water I quoted from A Diary in the Age of Water was based on current science by NASA and real predictions by scientists. It isn’t so much a question of what, but of when… Who will witness the change in the magnetic pole?

“The slow violence of free-market capitalism isn’t so much the deliberate and focused actions of a few evil men as the accumulated negligence of an undiscriminating collective of unimaginative humans.”
Lynna Dresden
“In her dystopian novel Canadian limnologist Nina Munteanu employs Solar Punk’s technique of using dystopic descriptions of present ecological catastrophe to predict the end of the world as we know it, and to indicate a utopian future.”
