The TVO and National Film Board of Canada film Borealis by Kevin McMahon opens with ‘tree song’ and Diana Beresford Kroeger’s voice: “The design of Nature is music. If you listen to the trees, you will hear their song. And some people actually hear an individual song for certain species.”
Early in the film, you see Edmund Metatawabin, a Fort Albany First Nation writer, walking ghost-like in the forest. His voice tells us that when the trees look at us, we would just be like “these little things flitting by.” This simple comment underscores the difference that time plays to a tree that may live to a thousand years in contrast to a human who—if they are lucky—may live to a hundred. Says Metatawabin:
“We have a certain relationship with the trees, their living essence. The tree has been here for a long time, standing in the same spot but watching…They’re our older relations. We’re very happy and secure that they’re there, still standing watching over us. Some of us have heard them sing.”

Boreal forest after a natural fire (Borealis)
In a frank interview with Madeline Lines of POV Magazine about the making of Borealis, filmmaker Kevin McMahon talked about how the rugged beauty of the boreal forest belies a fragility poised on a precarious balance with humanity.
The film discusses some of the major relationships and mechanisms of this complex and unique ecosystem through the voices of scientists and naturalists who study and know the forest: botanists, population and aquatic ecologists, atmospheric scientists, forest entomologists and researchers and guides.
“The story of the boreal forest [is that] basically … it goes up, burns itself down and like a phoenix, goes up again,” says McMahon. “There’s a complexity—the trees influence the animals, the animals influence the trees, so a community grows up over at least two centuries, usually, and sometimes three, or four.”
Natural fire cycles through the boreal forest every hundred years to renew it (Borealis)
One of the narrators tells us that the boreal forest has “survived and thrived in this regime of semi-regular stand-renewing fire.” This natural cycle of creative destruction is common in most ecosystems where destruction engenders rebirth and renewal by a community of species well-adapted to these cyclical changes. Botanist Diana Beresford-Kroeger adds, “the jack pine cones will only open on fire. The resin needs to be melted off the cone and then they shed their seeds.” The cones of tall spruce trees aggregate at the top of the tree, where the fire provides enough heat to open them but not burn them. White birch saplings sprout—phoenix-like—from the burnt tree base and roots. Aspen roots also send up thousands of suckers to become new clone trees of a renewed forest. The dead trees provide substrate for mosses, lichens and fungi that bring in moisture and decompose the logs into nutrients used by the living forest.

The movie showcases some of the most vivid details of tree function, including the microscopic view of opening and closing stomata (pores on a leaf). Stomata take in CO2 and release oxygen during photosynthesis. They also release water vapour as part of transpiration and other chemicals such as metabolic aerosols.

The devastation of climate change strongly features in the film as does our own mismanagement of the forests. A particularly telling scene was shot in the Yukon by Joshua See where squirrels have co-evolved with spruce trees in a relationship they’ve developed over 1000 years. The squirrels have timed their reproduction with the spruce production of cones and release of seeds; but climate change has knocked the trees out of sync with the squirrels, which is threatening the survival of the squirrel.

“I think that’s probably the first time any human being has seen such a vivid example of the rhythms of nature being thrown out of sync by climate change. And the funny thing is, if you listen to the climate change debate, as I obviously do fairly closely, that is something that has not really sunk in with the general public,” said McMahon. “People know about storms, and because of Australia and California they’re starting to learn about the impact it has on fires. But the reality that the rhythms of the world are all screwed up has not really sunk in, and Borealis has two really powerful examples of this. One is what happens to the squirrels, and the other is what’s happening to the trees, with what’s happening with the pine beetles.”

McMahon then adds soberly, “That last big dramatic drone shot [in the film] where you see that, basically, the boreal forest is dying – that’s Jasper National Park. This iconic forest that Canadians have sort of hung their identity on – you know, the snow-capped pine trees, and whatever – that forest is dying. It’s in a death spiral.”
McMahon admits: “I didn’t know when I started this project 10 years ago about the state of the forest. I was intending to make a film about how the forest worked. I did not realize until I started really talking to scientists that it is dying…The boreal forest is dying, and we are doing a super shitty job of taking care of it.”
This resonated particularly with me; I’d just published my latest eco-novel A Diary in the Age of Water with Inanna Publications. The novel—about four generations of women and their unique relationship with water—begins with a blue being in the unknown future as she runs through a dying forest of the north, the last boreal forest in the world…

McMahon adds a sober note about Canadian awareness:
“I think that in Canada – and this has been a theme of mine for decades – we pat ourselves on the back for being fresh faced boy scout-types, and we have this sense of ourselves as being green because we have so much green. The best thing about my career is I’ve been able to travel so much around this country. And it is a huge, huge country, and we do have just incredible, astonishing wilderness here–and we are wrecking it. We’re wrecking it in an extremely heedless, pointless, stupid kind of way. So I want that to sink in with people.
All those people at the end of the film that talk about the fact that the forest is collapsing, and we’re going to end up with a shrubland, and the forest emits more carbon than it sequesters–those are all Canadian government scientists. They’re not environmentalists. There’s no environmentalist voice in this film, in fact. I didn’t go to Greenpeace or any of those kinds of people, I went only to people who have a direct, material day-to-day interaction with the forest. Those people at the end of the film are on your payroll, and their job is to figure out what’s going. That’s what they’ve figured out, and I don’t think hardly anybody in this country knows that.”
Kevin McMahon
But McMahon remains hopeful. He cites Ursula Franklin, a scientist and peace activist who said, “Despair is a luxury we cannot afford.” McMahon responds with, “That’s the model that I live by really, because if I didn’t have hope I wouldn’t bother making these films, I’d just retire.”
Tree planter Isabella plants spruce and pine in a clearcut (Borealis)
Near the end of the film, tree planter Isabella reminds us that, “We have the ability to make whatever it is that we imagine, so let’s just start imagining a new path, let’s start imagining a new way. We are so tied to this experience and whatever happens to that forest is going to be a reflection of what happens to us.”
The film ends with the powerful wisdom of indigenous writer Edmund Metatawabin:
“We are here to make sure that the world, that the species, that humanity continues. The trees are the support, guidance, encouragement, and faith that things are just the way they’re supposed to be. That’s support from something that’s inanimate it looks like; but you’re getting it because it’s connected to the ground and its aiming for the sky. It’s a conduit between the earth and the sun. To see the tree as a living light … When you see that light you’ve gotten a gift; you’re going to be very humbled.”

You walk toward English Bay to the nearest Hydrogenase Hub, where you are meeting with your team to discuss the presentation.
The hub is a floating algal farm. The farm and the elongated seed-shaped airship docked at its centre both produce biofuel—essentially hydrogen—from the microorganism Chlamydomonas reinhardtii. Your mom, a former environmental consultant and algal scientist—now she writes science fiction—explained to you that this unicellular organism has both plant and animal properties; it carries out photosynthesis but is also heterotrophic (able to use organic carbon to grow) and will in the absence of oxygen produce gaseous hydrogen and metabolites such as formate and ethanol through hydrogenase enzymes. Chlamydomonas reinhardtii was first discovered as a clean source of hydrogen back in 1939 by German scientist Hans Gaffron at the University of Chicago (ironically the same year Germany invaded Poland). Gaffron called it “photosynthetic hydrogen production by algae”; and today it is a process that produces electricity and biofuel with zero emissions.
The algae farm recycles CO2for the bio-hydrogen airship you will be boarding after your meeting in the hub. You enter the airy station, whose honeycomb circular design resembles a stylized lily pad and glance up through the high nano-glass ceiling toward the elongated seed-shaped transport rising ten stories above you. The sun glances off the diaphanous double helix frame that resembles a freshwater spirogyra. The hub you’re standing in is a floating algae farm with solar cells on top and hydro-turbines below to capture tidal energy.

The sun glances off the diaphanous double helix frame that resembles a freshwater spirogyra. The hub you’re standing in is a floating algae farm with solar cells on top and hydro-turbines below to capture tidal energy.
The concept is the “subversive architecture” of Belgian architect Vincent Callebaut and inspired by the principles of biomimicry, coined by Janine Benyus in 2002 in her book “Biomimicry: Innovation Inspired by Nature”. Callebaut conceived Hydrogenase in 2010 as a 100% self-sufficient and zero-emission transport system using algae. He claimed that a hectare of seaweeds could produce 120 times more biofuel than a hectare of colza, soya or sunflower without consuming land needed for crops or forests. He called Hydrogenase a true miniature biochemical power station. Able to absorb CO2 as the main nutrient through photosynthesis the algae, under anaerobic conditions, produce hydrogen in vitro or in bioreactors.
You swipe your PAL over the ticket booth sensor and the optional ticket-brochure pops out. You take it and read the specs between glances at the tall vessel loading in the dock of the hub. It’s really like a vertical dirigible, you think, studying the seed-shaped airship with self-cleaning “intelligent” nanostructured glass—inspired by the lotus leaf that doesn’t get wet. The semi-rigid unpressurised airship stretches vertically around an arborescent spine that twists like chloroplast ribbons 400 meters high and 180 meters in diameter.
You read that each Hydrogenase airship is covered with flexible inflatable photovoltaic cells and twenty wind turbines to maneuver and collect energy. The interior spaces provide room for housing, offices, scientific laboratories, and entertainment, and a series of vegetable gardens that provide a source of food while recycling waste.
You read that this self-sufficient organic transport flies about 2000 meters high at about 175 km/hr (twice the speed of a conventional ship). Given its ease in negotiating airspace and its ability to land and take off from virtually any location, the Hydrogenase is used by many groups in various capacities. Your friend Michael who teaches at the University of Victoria uses one as a mobile research station in his studies along the coast of northern British Columbia.
The vessel is made of “intelligent layers” and “self-separable ceramics”. Its bionic coating draws inspiration from sharkskin that is self-cleaning and flow-efficient.
Hydrogenase concept with algal farm pods and air ships
You head down the spiral staircase to the third subsea level toward the meeting room you booked earlier on your PAL. The view is spectacular from here through the nano-glass panes. Rays of shimmering light stream through a gently swaying forest of kelp. You glimpse the sun-glinted flickering of hundreds of anchovies as they school through the kelp. This floating farm is an organic purifying station of four carbon wells where the algae recycle the carbonated waste brought by the airships and, in turn, feed the airship with biohydrogen. It’s the new “gas station”, you reflect with a smile.
After your meeting with staff, you and three others of your team board the airship and settle in one of the skyview chambers. The journey is relaxing, like the BC Ferry used to be, but without the pungent smell and pollution of conventional motorized sea vessels. It’s a quiet and relaxing trip with a spectacular view of the Gulf Islands. Your team strategizes your presentation over a light lunch and Matcha lattes.
Vincent Callebaut’s Hydrogenase
The PA system sounds and a woman’s voice informs you that the ship will be making an emergency landing on Saturna Island to rescue two hikers injured at East Point. This will only add twenty minutes to the trip, the woman assures you. You don’t mind and recall the disclaimer at the bottom of the ticket. Given the ability of this airship to take off and accurately land virtually anywhere, all Hydrogenases are by law mandated to be on standby for rescue missions in rough terrain.
You pull out the ticket and read again: The Hydrogenase is affiliated with the International Red Cross and BC Coastguard. The Hydrogenase must by law respond to any distress call at sea or rough terrain associated with coastal waters. Because of this service, we cannot guarantee a timely schedule.
You recall how Hydrogenases were deployed in the last hurricane disaster off the coast of Florida last year, saving countless people trapped in the flooding that accompanied the storm. The International Red Cross uses them as flying hospitals.
Bernard frets over the time delay. He is concerned about the lack of preparation and set up time once you get into Victoria. You assuage him gently. The best preparation is sincerity, you tell him. The landscape architect Thomas Woltz, whose work you highly respect, saw himself as someone who embraces the complexity of modern life while seeking meaning and narrative in both natural and human-made environments.
“We’re storytellers,” you tell Andre. Invoking metaphor through design. “They know we’re coming and they know we’re helping someone; they’ll wait for our story. And it’s all about harmony.”
The lines of Henry David Thoreau come to you: Man’s life must be of equal simplicity and sincerity with nature, and his actions harmonize with her grandeur and beauty.
Then you point your PAL at the ServiceBot and order three more lattes. You lean back in your bamboo fabric chair and cross your legs over the leg rest.
It’s a brave new world.

In my recent eco-novel A Diary in the Age of Water the limnologist Lynna makes the following entry in her diary in 2057:
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. —A Diary in the Age of Water
Earth’s magnetic field
In a 2019 article in New Atlas, David Szondy tells us that “North isn’t quite where it was after the Earth’s north geomagnetic pole made an unexpected sprint across arctic Canada.” Apparently the magnetic pole is moving faster than predicted. The shift is caused by a push/pull between two patches of magnetic field—one under Canada and another under Siberia. The Canadian one appears to be weakening…
Every few hundred thousand years our magnetic field reverses—with the magnetic north switching places with the magnetic south. The last major geomagnetic reversal occurred 780,000 years ago. Between the full geomagnetic reversals—which can last up to 10,000 years—shorter disruptions occur. These are called geomagnetic excursions and are short-lived, involving temporary changes to the magnetic field that last from a few hundred to a few thousand years. The most recent recorded geomagnetic excursion is called the Laschamps Excursion some 42,000 years ago.
“The Laschamps Excursion was the last time the magnetic poles flipped,” explains Chris Turney, one of the lead scientists of a study reported in Science. “They swapped places for about 800 years before changing their minds and swapping back again.”
Although scientists have known about these magnetic pole events, they have not clearly understood their impacts on life and the environment. A study published in the journal Science reported on a recent discovery in New Zealand of an ancient kauri tree, that not only confirmed the time of the magnetic collapse, but shed some light on the dramatic period of environmental change, particularly in the time leading up to the few hundred years the Earth’s magnetic field was reversed. These included a depleted ozone layer, higher levels of ultraviolet radiation, and increased atmospheric ionization, all coalescing about 42,000 years ago in the Laschamps Excursion. “Early humans around the world would have seen amazing auroras, shimmering veils and sheets across the sky,” says Alan Cooper, one of the lead scientists. “It must have seemed like the end of days.”

The researchers also speculated that the magnetic field disruption led to an influx of cave art, driven by the need to seek shelter from the increase in ultraviolet rays—particularly during solar flares. The researchers also suggested that the event prompted the extinction of several megafauna in Australia and the end for Neanderthals—whose extinction occurred around 42,000 years ago.
Cooper points to the current movements of the north magnetic pole across the Northern Hemisphere as a potential warning sign of an impending event.
“This speed – alongside the weakening of Earth’s magnetic field by around nine per cent in the past 170 years – could indicate an upcoming reversal,” says Cooper. “If a similar event happened today, the consequences would be huge for modern society. Incoming cosmic radiation would destroy our electric power grids and satellite networks.”

Terraforming Mars (images by NASA)
Making Mars Inhabitable By Re-establishing its Magnetic Field
“Our quest on Mars has been to ‘follow the water’ in our search for life in the universe, and now we have convincing science that validates what we’ve long suspected,” said NASA’s John Grunsfeld.”This is a significant development, as it appears to confirm that water – albeit briny – is flowing today on the surface of Mars.”
That was step one. Mars was once just like Earth, with a thick atmosphere and lots of water.
In a 2017 article in Science Alert, Peter Dockrill reported that “NASA wants to launch a giant magnetic field to make Mars habitable.” This bold plan was to give Mars its atmosphere back and make it habitable for future generations of human colonists consists of launching a giant magnetic shield into space to protect Mars from solar winds. With the shield in place, scientists argued that we could restore the atmosphere and terraform the Martian environment so that liquid water flows on the surface again. Mars once had a thick atmosphere like Earth currently has.
In 2018 NASA concluded: “Our results suggest that there is not enough CO2 (carbon dioxide) remaining on Mars to provide significant greenhouse warming were the gas to be put into the atmosphere; in addition, most of the CO2 gas is not accessible and could not be readily mobilized. As a result, terraforming Mars is not possible using present-day technology.”
Then in 2019, Harvard scientists proposed a way around the problem of insufficient CO2 for greenhouse warming. They proposed that by “covering certain areas of the Martian surface with a thin layer of silica aerogel, namely areas with large amounts of water ice, enough sunlight will come through for warming and combine with natural heating processes beneath the surface to create a potentially habitable environment.”
The study demonstrated through experiments and modelling that under Martian environmental conditions, a 2–3 cm-thick layer of silica aerogel would simultaneously transmit sufficient visible light for photosynthesis, block hazardous ultraviolet radiation and raise temperatures underneath it permanently to above the melting point of water, without the need for any internal heat source.
“Once temperatures were adequate, the gases released from the ice in the lakes and regolith (soil) would build up to form a pressurized atmosphere under the aerogel layer. If successful up to that point, microbes and plant life could theoretically survive. “Placing silica aerogel shields over sufficiently ice-rich regions of the Martian surface could therefore allow photosynthetic life to survive there with minimal subsequent intervention,” the scientists suggested. This photosynthetic life would go on to produce oxygen for pickier Earth dwellers to utilize,” reports Dacia J. Ferris of Teslarati.
p.s. I’m sure I’m not the only one who sees the irony of this situation: Mars has insufficient CO2to warm its atmosphere, when Earth suffers from an excess of this greenhouse-warming gas. While going to Mars is one of my dreams (quite unrealizable for me; but I’m allowed to dream, no?), I still harbor an unsettling feeling that comes with the uncertainty about our prowess and respect in this endeavor. We haven’t exactly been successful in controlling our own runaway global warming or other degradation of our living ecosystems. Read Ray Bradbury’s Martian Chronicles to get my meaning.

Cedar roots dusted in winter snow, Jackson Creek Park, ON (photo by Nina Munteanu)
.
It’s late December in the old-growth riparian forest of Jackson Creek, Peterborough. A light snow is falling on the cedars. When I walk by the creek through this deep forest, my senses reach out like tendrils, touching the mysteries of Nature’s complexity. To my right, the river’s multi-timbral chorus gurgles and chortles in chaotic symphony. Occasionally, I hear the percussion of ice cracking and booming like a designer rearranging furniture. The cedar pine forest sloping up to my left hisses and giggles as the snow falls and melts. My footfalls crunch over a frozen sponge of litter and loam. Nature’s sounds and aromas coarse through me like sweet nectar and my soul rejoices. I quiet my mind and become one with all of it. Serene in discovery. In sensing. Feeling. Embedding. I’m awestruck with the simple beauty of complex form, pattern and purpose: from the tiniest moss covering a boulder erratic to the largest cedar trees creaking and swaying above me in the whisper of a brisk winter wind.
Today is different.
I see something unexpected. A skull.
.

I’ve been following the icing of Jackson Creek. Huge ice “islands” have formed over boulders, creating new channels for the freezing water to coarse around. I stop near a small tributary of the river to study the formation of ice “pearls” on either side of an ice-formed channel. I venture out onto an ice shelf and set up my small tripod to take slow shots of water magic. The sun paints the water a brilliant turquoise hue.

Breathing hard from my efforts and satisfied with the shots I’ve taken, I stand up and step back from the shore. It’s then, as I look down to where I’ve placed my feet, that I see it. A small white “rock”—No! A skull! Embedded in the frozen leaf litter and ground, not more than several centimetres from the frozen shore of the river, lies an animal skull the size of my hand with a long snout. How have I managed not to step on it and crush it with all my tramping there? I must have stepped past it several times to get to my photo op. I bend low to get a better look. What is it doing there? Who—or what—had brought it there, depositing it on the creek shore?
I returned the next day, eager to show my discovery to a friend and naturalist; she suggested it was a red fox. Excited, I returned the following day with a ruler to measure it and a trowel and some hot water to help me extricate it for better examination. A light snow had fallen the night before but the top of the skull was still visible. I removed the snow and the skull came out of the ground rather easily, revealing several back teeth still embedded in it. While the skull was mostly intact, the lower jaw was missing and a loose tooth lay on the ground below it. I removed my prize and brought it home. After cleaning it with some bleach, I examined it further.

The skull showed no signs of trauma or injuries to the head. I guessed that while this fox was an adult, it was young; the teeth that were there were in excellent condition. The skull measured 133 mm from end of snout to external occipital protuberance (inion). The average skull length of an adult male measures 129 to 167 mm and vixens 128-159 mm. Steve Harris in BBC’s Discover Wildlife tells us that dog foxes also tend to have broader and more domed skulls than vixens; my skull was rather sleek, I thought. From this I guessed that the skull belonged to a young adult female, a vixen. Statistics for fox deaths also favoured a young fox (see below).

I couldn’t help wondering about this fox which had appeared as if by magic at my feet. What was Vera Vixen’s story? (Somewhere between bringing her home and cleaning her, I decided to name her). How did Vera meet her demise and where was the rest of her? Had the skull recently washed onshore or was it recently brought to the shore by a scavenging racoon, badger (they’re more common in this area than most people think) or another fox? Or had the skull been there longer and the winter ice and water just washed away the litter to reveal the embedded skull? Was it a death of misadventure? Had Vixen drowned when Jackson Creek flooded? Or was she hit by a car at the edge of the park, torn up by scavengers and her skull brought here to eat? Jake McGown-Lowe of BBC’s The One Show shares that “Fox bones are hard to find.” He had found his specimens at the edge of a wood. “In the countryside the main predator of foxes are farmers and gamekeepers, especially around lambing time, and the gamekeepers usually take the bodies away to dispose of.” Jackson Creek is an urban park. Thirty percent of its perimeter is surrounded by urban and suburban streets of Peterborough; sixty percent of the park is surrounded by farmland and some marsh at its upstream end. A Bristol University study on cub survival determined that major sources of mortality included hypothermia, attack by domestic dogs, attack by badgers, and death of the mother.

Various hunters have indicated that in a temperate climate it takes several weeks to several years for decomposers (insects, fungi and bacteria) to clean a skull left in the elements of nature. Temperature, humidity, presence of insects and water play key roles in the process of skeletonization. The skull at my feet could have died as recently as the fall of 2020 and as long ago as spring of 2019 during lambing season. Had Vera been shot or poisoned (including indirectly through scavenging) as she hunted for her kits?
Bristol University estimated that two thirds of the fox population die each year by predators (including humans), disease and vehicles with the single largest cause of fox mortality being through road collisions. An Oxford study corroborated this with observations that 60% of the fox population were run-over by vehicles. Apparently most of the fox deaths are the young. In their 2004 review of the red fox, David Macdonald and Jonathan Reynolds at Oxford noted that “roughly 75% of the fox population die in their first year.” Studies in Europe have also shown that three to seven-month old foxes are most susceptible to traffic collisions—associated with the cub’s increase in ranging behaviour around the den and their lack of experience—and larger propensity for misadventure.
BBC Wildlife Magazine tells us that “spring is a good time to look for mammal skulls. The end of winter is a peak period of mortality for many species, and skulls can be found virtually anywhere.”

The red fox (Vulpes vulpes) is one of Canada’s most widespread mammals, living in a wide range of habitats including forests, grasslands, meadows and farmland. Known for their ability to adapt quickly to new environments, foxes have adapted well to urban settings and ecotones between city and wilderness; in fact, they prefer mixed vegetation communities such as edge habitats and mixed scrub and woodland. They are highly athletic, agile and incredibly fast (they can run up to 30 mph); foxes are known for pouncing on mice and other small rodents, burrowing in the snow using the earth’s magnetic field to help them hunt. Foxes have good visual acuity, capable of seeing small movements from far away and for navigating dense forests as they sprint after prey; but their most useful sense is their ultrasonic hearing. Treehugger reported on a 2014 study by the University of Duisburg-Essen and Czech University of Life Sciences who discovered that “red foxes have the best known maximal absolute hearing sensitivity of any mammal. They can hear a mouse squeak from 100 feet away.” This along with their ability to move swiftly and quietly through most terrain makes them effective crepuscular (dawn and dusk) predators in open country and nocturnal hunters in areas of concentrated human habitation. Foxes generally live an average of 3-7 years in the wild.
Foxes are monogamous. They live in family units in which both parents take equal part in raising their young. Older siblings also care for the young pups. The young kits remain with their parents at least until the fall of the year they were born in and sometimes longer, especially females. Pups are typically born from February-April. They are born blind, deaf and toothless, with dark brown fluffy fur. Mom fox stays close to guard the kits and nurse them for several weeks and the father or barren vixens feed the mothers. The kits leave the den a month after and are fully weaned by 8-10 weeks. The mother and her pups remain together until the autumn after the birth. After the pups are weaned and begin to play about the den’s entrance, Dad fox helps watch them while Mom fox gets in some hunting. If the mother dies, the father takes over caring for the pups. Kits reach adult form by seven months and some vixens reach sexual maturity by ten months—enabling them to bear their first litter at one year of age.
Red foxes help balance ecosystems by controlling population of prey animals such as rodents and rabbits. They also disperse seeds by eating fruit. Steve Hall of Adirondack Almanack reminds us that red foxes play an important ecological role:
“Now and then, vulnerable farm animals such as chickens, ducks and lamb will be taken. While farmers used to routinely trap foxes, many now realize that the fox brings far more benefit in its constant predation on crop-destroying rodents and insects, than the harm they cause in taking the occasional barnyard animal; secure enclosures for hens and [use of] guard dogs to keep the fox in the field but out of the barnyard, are the key to discouraging unwanted fox predation.”
James Fair of BBC Discover Wildlife noted that a single fox during its lifetime may be worth £150-190 to a farmer through rabbit predation. Most farmers in Wiltshire consider the fox a helpmate in reducing the pest of rabbits. Hall adds that while, “Deer are significant carriers of the tick, Lyme disease starts with rodents… [the red fox] eats huge quantities of rodents. If for no other reason, fox hunting and trapping should be banned.”

Foxes take shelter in thickets and heavy bushes in the autumn until March of the next year. They are omnivores with a varied diet of small mammals such as voles, mice, squirrels and rabbits, and a variety of plants, berries, other fruit and nuts. Foxes have good eyesight but very keen hearing and sense of smell; this along with their ability to move swiftly and quietly through most terrain makes them effective crepuscular (dawn and dusk) predators in open country and nocturnal hunters in areas of concentrated human habitation. Foxes generally live an average of 3-7 years in the wild.
The red fox communicates through a wide range of body language and vocalizations. Foxes use scent glands and urination to communicate their individuality through their skunk-like smell. They use scent to mark territory and show status. The smell increases during mating season. The fox vocal range spans across five octaves with at least 28 different sounds that include those for “contact” and those for “interaction.” Individual voices can be distinguished. One contact sound between two foxes approaching one another resembles the territorial call of a tawny owl. When foxes draw close together, they use a greeting warble similar to the clucking of chickens. Adults greet their kits with gruff huffing sounds.
Red foxes feature prominently in the folklore and mythology of human cultures with which they are sympatric. In Greek mythology, the Teumessian fox or Cadmean vixen, was a gigantic fox that was destined never to be caught. The fox was one of the children of Echidna. In Japanese mythology,the kitsune are fox-like spirits that possess magical abilities which increase with age and wisdom. This includes the ability to assume human form. Some folktales suggest that kitsune use this ability to trick others; others portray them as faithful guardians, friends and love. In the Cotswolds, witches were thought to take the shape of foxes to steal butter from their neighbours. In later European folklore, Reynard the Fox symbolizes trickery and deceit. In the actual world, this translates to resourcefulness, a quick study, and swift and decisive action. And perhaps that is the true meaning of Vixen.

Fox teaches us that gender equality helps to create a strong family, says Chris Lüttichau, author of Animal Spirit Guides. Fox’s medicine is family, survival and voice. Fox embodies resourcefulness and daring in her quest to feed herself and her young. “Fox survives and flourishes because she is clever and adaptable; she is now found living in cities. Fox teaches us to be flexible rather than to resist change.” According to Lüttichau, Fox’s medicine is “swiftness, surefootedness and a quick mind that always knows what to do.” Foxes have a wide vocal capacity and range, from screams and calls to low barks—something for each case as the fox calls and listens and calls back. We can learn from Fox’s varied voice to transcend traditions and prejudices through healing council and stories.
With thoughts returning to my Vera Vixen, I think that perhaps she is not a young unlucky fox who met with misadventure after all; rather, she’s a smart old vixen who’s birthed and nurtured several litters of four to six kits each spring. Her natural death after four to seven years of a rich life in the old growth forest and marsh of Jackson Creek would have led her to a quiet place to lay herself to rest; there her corpse was ultimately found by a badger, racoon or other fox and parts of her scattered throughout the forest to decompose and feed the ecosystem. Ever the mother, Vera now feeds the forest that nurtured her and her family’s existence.

The Story of Fleet, the Fox of Surrey: In January 2014 it was reported that “Fleet”, a relatively tame urban red fox tracked as part of a wider study by the University of Brighton in partnership with the BBC’s TV series Winterwatch, had unexpectedly traveled 195 miles in 21 days from his neighbourhood in Hove, at the western edge of East Sussex, across rural countryside as far as Rye, at the eastern edge of the county. He was still continuing his journey when the GPS collar stopped transmitting due to suspected water damage. Along with setting a record for the longest journey undertaken by a tracked red fox in the United Kingdom, his travels have highlighted the fluidity of movement between rural and urban red fox populations.
Fox Prayer for 2021:
I call on Fox. Shapeshifter and trickster. Edge-walker and messenger. Help me blend with my surroundings and adapt to the changing landscapes. Show me the hidden paths between the worlds. Teach me the ways of invisibility and camouflage. Gift me your keen senses that i might see more of what is around me and use it to accomplish my goals. I call on you, Fox, to bring magic and discernment into my life. Lead me at your steady gait to those places where I might do the greatest good. Let us walk the borders between day and night and follow the scent of divine mischief. Fox, I call on you.

Jackson Creek Old-Growth Forest:
Jackson Creek Old-Growth Forest (OGF) is a 4.5 hectare urban forest located on a glacial spillway slope littered with granite erratic boulders. The OGF lies within the Jackson Creek Riparian Forest, a 92-ha valley land forest which extends into a major wetland of importance. Dominant conifers in the OGF include white cedar (Thuja occidentalis), white pine (Pinus strobus), and eastern hemlock (Tsuga Canadensis). Sugar maple, American beech, yellow birch, white ash and white oak contribute to the mixed riparian forest. Trees are commonly over 150 years old with some reaching over 250 years. Largest trees—which tend to be the pines and cedars—reach diameters of 97 cm dbh and heights of 35 metres.

The Jackson Creek valley was formed by the torrent of glacial meltwater that flowed from the ancient Lakes Algonquin and Jackson through the overlying till to create a glacial spillway some 12,000 years ago (Adams and Taylor 2009); the outflow of glacial Lake Algonquin was channeled to the former glacial Lake Iroquois—a body of water larger than the current Lake Ontario but in the same general area (Ecclestone and Cogley 2009).
The Jackson Creek OGF is a good example of a mature White Cedar—White Pine—Eastern Hemlock stand on a glacial spillway slope in Ecodistrict 6E-8. This eco-district extends in a band from south of Lake Simcoe eastward to the Bay of Quinte, north of the Oak Ridges Moraine, and is characterized by rolling till plains with drumlins, eskers, and intervening wide river valleys (Hanna 1984).

I understand something of paradox. As an ecologist, I deal with it all the time. Destruction in creation and creation in destruction lies ingrained in the life-cycles of everything on this planet. A forest fire can destroy life but in so doing creates a more vibrant, healthier forest. Nature reveals many such examples from its circular patterns and fractal self-organization to its infinite spirals.
The Ouroboros is an ancient symbol depicting a serpent or dragon swallowing its own tail to form a circle. It represents self-reflexivity or cyclicality, especially of something constantly re-creating itself. As the serpent devouring its own tail, the Ouroboros symbolizes the cyclic Nature of the Universe: creation out of destruction, Life out of Death. The ouroboros eats its own tail to sustain its life, in an eternal cycle of renewal. In Gnosticism, the ouroboros symbolizes eternity and the soul of the world.
Ecologist C.S. Holling recognized ecosystems as non-linear, self-organizing and continually adapting through cycles of change from expansion and prosperity to creative destruction and reorganization. In his classic paper, entitled: “Simplifying the complex: the paradigms of ecological function and structure” (1987), Holling suggested that the experience of instability maintains the structure and general patterns of ecosystem behaviour; that Nature ‘learns’ and accommodates with time.
In the final analysis, it is a matter of scale.
We can’t expect the natural world around us to run smoothly and safely for our benefit. New diseases, pollution, species extinction, and climate change are all results of unexpected impacts, whether human-caused or not. Though incredibly elegant, Nature is not simple. Scale is something you can’t see or easily measure and assess if you are in it. Scale is like hindsight.
The systems of Gaia are complex from the tiniest cell to the complex planet itself. Weather, for instance, is a “chaotic system” that displays a fractal structure and a range of chaotic behaviour on many scales. Temperature, air pressure, wind speed and humidity are all sensitive to initial conditions and interrelated in multi-scales.
Says Brian Arthur, professor at Stanford University:
The complex approach is total Taoist. In Taoism there is no inherent order. “The world starts with one, and the one become two and the two become many, and the many lead to myriad things.” The universe in Taoism is perceived as vast, amorphous, and ever changing. You can never nail it down. The elements always stay the same, yet they are always arranging themselves. So, it’s like a kaleidoscope: the world is a matter of patterns that change, that partly repeat, but never quite repeat, that are always new and different.
BRIAN ARTHUR
Western scientists are just beginning to appreciate this through the application of complexity theory and chaos theory. This is something the eastern world has “known” since ancient times: humility before nature; respect for richness and diversity of life; generation of complexity from simplicity; the need to understand the whole to understand the part.
I wish you a safe and wealthy 2021: a year’s wealth of unexpected wonder, of genuine love, of unguarded honor, and dazzling bravery. There is no wonder without tolerance; no love without humility; no honor without sacrifice; and no bravery without fear. I wish you the gift of unbridled compassion.
As Dante Sarpé (in my story, Arc of Time) said: Without compassion to fill it, knowledge is an empty house, casting its shadow on our courage to embrace the paradoxes in our lives: to feel love in the face of adversity; grace when confronted with betrayal.
Happy New Year!

I would have collected slimy waters from the scum ponds and murky puddles near my house. I would have brought them home and exposed them to the light of my microscope. I would then have peered deep into a secret world, where shady characters and alien forms lurked and traded.
It would be many years, when I was in college, before I finally witnessed this world—so alien, it might have inspired the science fiction books I wrote later as an adult. As it turned out, I was led to pursue a Masters of Science degree, studying periphyton (microscopic aquatic communities attached and associated with surfaces like rocks and plants) in local streams in the Eastern Townships of Quebec.

While my work focused on how diatoms (glass-walled algae) colonized surfaces, micro-invertebrates kept vying for my attention. Water fleas (cladocerans), copepods, rotifers, seed shrimps (ostracods) and water bears sang across my field of vision. They flitted, lumbered, wheeled and meandered their way like tourists lost in Paris. But this wasn’t Paris; I’d taken the blue pill and entered the rabbit hole into another world…

The Secret—and Dangerous—World of Micro-Organisms
Small Freshwater habitats are home to a highly productive and diverse collection of micro-invertebrates—multicellular animals that can barely be seen with the naked eye. Many average from 0.5 to 1 mm in size and resemble little white blobs; however, a scholar can distinguish each invertebrate by its unique movement. For instance, when presented with a jar of pond water, I can usually distinguish among the wheel-like wandering of a gastrotrich, dirigible-like gliding of an ostracod (seed shrimp), the vertical goldfinch-style “hopping” of the cladoceran (water flea) as it beats its antennae, or the halting-jerking movements of copepods (oar-feet) as their antennae drive them along like a dingy propelled by an amateur oarsman.
Alas, puddles, ephemeral ponds and vernal pools pose sketchy habitats, given their tendency to appear and disappear in a wink. And like the thief in the night, they pose a harsh and uncertain home to many small organisms. These environments are ever-changing, unstable, chaotic and unpredictable. Yet, anyone who has studied these variable ecosystems understands that they team with life.
When a puddle or ephemeral pond dries up then reappears with rain, how can these communities thrive? Or do they all die off and then somehow recruit when the pond reappears? Many of these invertebrates have evolved creative ways to survive in very unstable environments. Some form a resting stage—a spore, resting egg or ‘tun’—that goes dormant and rides out the bad weather.

Animalcules & the Bdelloid Rotifer
In 1701, Antonie van Leeuwenhoek observed that “animalcules” (likely the bdelloid rotifer Philodina roseaola) survived desiccation and were “resurrected” when water was added to them. He’d discovered a highly resistant dormant state of an aquatic invertebrate to desiccation.
Dormancy is a common strategy of organisms that live in harsh and unstable environments and has been documented in crustaceans, rotifers, tardigrades, phytoplankton and ciliates. “Dormant forms of some planktonic invertebrates are among the most highly resistant … stages in the whole animal kingdom,” writes Jacek Radzikowski in a 2013 review in the Journal of Plankton Research. Radzikowski describes two states of dormancy: diapause and quiescence. (on right: sketch of bdelloid rotifer by Nina Munteanu)
Bdelloid rotifers can go into quiescent dormancy at practically any stage in their life cycle in response to unfavorable conditions. Early research noted that dormant animals could withstand freezing and thawing from −40°C to 100°C and storage under vacuum. They also tolerated high doses of UV and X radiation. Later work reported that some rotifers could survive extreme abiotic conditions, such as exposure to liquid nitrogen (−196°C) for several weeks or liquid helium (−269°C) for several hours. Desiccated adult bdelloid rotifers apparently survived minus 80°C conditions for more than 6 years. The dormant eggs of cladocerans and ostracods also survived below freezing temperatures for years.
Rotifers are cosmopolitan detrivores (they eat detritus) and contribute to the decomposition of organic matter. Rotifers create a vortex with ciliated tufts on their heads that resemble spinning wheels, sweeping food into their mouths. They often anchor to larger debris while they feed or inch, worm-like, along substrates. Some are sessile, living inside tubes or gelatinous holdfasts and may even be colonial. Rotifers reproduce by parthenogenesis (in the absence of mates), producing clones (like cladocerans). Resting eggs (sometimes called zygotes) survive when a pond dries up. Bdelloid rotifers don’t produce resting eggs; they survive desiccation through a process called anhydrobiosis, contracting into an inert form and losing most of their body water. Embryos, juveniles and adults can undergo this process. The bdelloid withdraws its head and foot and contracts its body into a compact shape called a tun; a generally unprotected dormant state that remains permeable to gases and liquids. Like Tardigrades, Bdelloid rotifers can resist ionizing radiation because they can repair DNA double-strand breaks.
The long-term survival and evolutionary success of bdelloid rotifers in the absence of sex arises from horizontal gene transfer via DNA repair.
In my eco-novel A Diary in the Age of Water the limnologist Lynna visits her technician Daniel as he peers through a microscope and makes the observation of why the bdelloid rotifer is well-suited to climate change:
I bent to peer through the eyepiece at what turned out to be a pond sample in a Petri dish. Attached to a pile of detritus shivering in the current, several microscopic metazoans—rotifers—swung like trees in a gale; they were feeding. Their ciliated disk-like mouths twirled madly, capturing plankton to eat. Watching them reminded me of my early research days as an honours undergrad at Concordia University in Montreal. Probably Philodina, I thought; I had seen many during my stream research in Quebec.
“They’re the future,” Daniel said, looking up at me with a smirk as I straightened.
I raised my eyebrows, inviting him to elaborate, which he cheerfully did.
“They’re the future because of their incredible evolutionary success and their ecological attraction to environmental disaster.” He knew he’d piqued my interest. “These little creatures have existed for over forty million years, Lynna. Without sex! And they’re everywhere. In temporary ponds, moss, even tree bark. Bdelloid mothers that go through desiccation produce daughters with increased fitness and longevity. In fact, if desiccation doesn’t occur over several generations, the rotifers lose their fitness. They need the unpredictable environment to keep robust.” They incorporate genes from their environment: they acquire DNA transposons—mobile DNA—through HGT.”
—A DIARY IN THE AGE OF WATER
The bdelloid all-female populations have thrived for millions of years by maintaining a robust and diverse population through epigenetics and DNA repair during dormancy…The dormancy of all-female bdelloids is an elegant technique to ride out harsh conditions. The bdelloids can go dormant quickly in any stage of their life cycle, and they’re capable of remaining dormant for decades. They can recover from their dormancy state within hours when the right conditions return and go on reproducing without the need to find a mate.
Highly variable environments tend to support rare species: organisms that are uniquely equipped for change. These are the explorers, misfits, and revolutionaries who do their work to usher in a new paradigm. They carry change inside them, through phenotypic plasticity, physiological stress response mechanisms, or life history adaptations. Like bdelloid rotifers going dormant through anhydrobiosis. Or blue-green algae forming dormant akinete spores. In tune with the vacillations of Nature, epigenetics-induced adaptation is the only option for keeping up with rapid and catastrophic environmental change, not to mention something as gigantic as climate change. That’s why the bdelloid rotifers survived for millennia and will continue for many more. They adapt by counting on change.

In 2007, when I started my first blog, The Alien Next Door, I wrote an article that explored the term “Darwin’s Paradox”—it’s not just the title of my science fiction thriller Darwin’s Paradox released that year by Dragon Moon Press—but a term coined by scientists to describe the paradoxical phenomenon exhibited by coral reefs.
Defying The Laws of Thermodynamics
Darwin described coral reefs as oases in the desert of the ocean. Coral reefs comprise one of the richest ecosystems on Earth, in apparent violation of the laws of thermodynamics (high productivity in a low-productivity environment). Productivity ranges from 50 to 250 times more than the surrounding ocean. How do they thrive in crystal-clear water, largely devoid of nutrients? Part of the answer lies in the coral’s efficiency in recycling nutrients like nitrate and phosphate.
First, the rough coral surface amplifies water turbulence at a microscopic level, disrupting the boundary layer that usually settles on objects under water and lets the coral “hoover” up the sparse nutrients. I stumbled upon a similar phenomenon during my grad work on temperate streams and published my serendipitous discovery in the journal Hydrobiologia. I was researching how periphyton (attached “algae”) colonized submerged glass slides and observed that the community preferred the edges of the slides because the micro-turbulence there provided more opportunity for attachment and nutrition.
Second, lots of corals also function symbiotically with specialized algae (called zooxanthelae), which provide the coral with food (through photosynthesis) and, in turn, get food from the wastes created by the coral.
Can the science of symbiosis teach us something about another Darwin’s Paradox?
The Evolution of Compassion
In a September 2013 article in the Jewish World Review, Boston Globe reporter Jeff Jacobywrote:
“Charles Darwin struggled with a paradox: If evolution is a struggle for survival, how could generosity, compassion, and other altruistic virtues have spread through natural selection? Darwin could see the clear evolutionary benefit to groups that inculcated ethical values in their members. Imagine two competing primitive tribes, equally matched — except that ‘one tribe included a great number of courageous, sympathetic, and faithful members, who were always ready to warn each other of danger, [and] to aid and defend each other.’ (Darwin, “The Descent of Man”). There was little doubt that tribes highly endowed with such virtues ‘would spread and be victorious over other tribes.’”
“How did any tribe evolve such ethical qualities in the first place?” asks Jacoby. Brave individuals who risked their lives for others “would on average perish in larger numbers than other men.” It hardly seemed possible, Darwin conceded, that, “such virtues … could be increased through natural selection, that is, by the survival of the fittest.” So, how did it and why?
Jacoby quotes Sir Jonathan Sacks, Britain’s Orthodox chief rabbi, who pointed to “the central drama of civilization: Biological evolution favors individuals,” says Sacks. “But cultural evolution favors groups.… Selfishness benefits individuals [only in the short-term and only in a limited way—my comment], but it is [ultimately] disastrous to groups, and it is only as members of a group that individuals can survive at all.”
Jacoby describes the vast literature in evolutionary psychology and sociobiology that have demonstrated humanity’s hard-wired moral capacity. “We are born with an aptitude for empathy and fairness,” said Jacoby, citing recent neurological experiments that have demonstrated that an act of generosity triggers a pleasurable response in the brain.
Abraham Lincoln summarized it in seven words: “When I do good, I feel good.” Psychologists call it the “helper’s high”. Neuroscientists and behavioral scientists are demonstrating unequivocally the benefits of altruism to our health and happiness. Scientists have designed experiments that actually trace altruism—and the pleasure we gain from it—to specific regions and systems in the brain. Key studies now provide striking evidence that our brains are wired for altruism.
The Social Brain and the Seat of Compassion
In a study published in the Proceedings of the National Academy of Sciences (Moll et al, 2006), a team of neuroscientists lead by Dr. Jordan Grafman, reported that, “when people made the decision to donate to what they felt was a worthy organization, parts of the midbrain lit up—the same region that controls cravings for food and sex.” The brain experiences a pleasurable response when we engage in good deeds that benefit others.
Dr. Grafman found that the subgenual area in the frontal lobe near the midpoint of the brain was also strongly active when his study subjects made the decision to give to charity. The area houses many receptors for oxytocin, a hormone that promotes social bonding. “The finding suggests that altruism and social relationships are intimately connected—in part, it may be our reliance on the benefits of strong interpersonal connections that motivates us to behave unselfishly,” reports Elizabeth Svoboda in the WallStreet Journal. The team also found that the nucleus accumbens, which contains neurons that release the pleasure chemical dopamine, was triggered when a person chose to help another.
A 2007 study headed by neuroscientist Scott Huettel and reported in Nature Neuroscience(Tankersley, et al., 2007) connects altruism to the posterior superior temporal cortex (pSTC), an area in the upper rear of the brain that lets us perceive goal-directed actions by someone or something else. Results suggest that altruism depends on, and may have evolved from, the brain’s ability to perform the low-level perceptual task of attributing meaning and motive in the actions of others.
“Our findings are consistent with a theory that some aspects of altruism arose out of a system for perceiving the intentions and goals of others,” said Dr. Huettel. “To be altruistic, you need to see that the people you’re helping have goals, and that your actions will have consequences for them.”
Research led by Michael Platt reported in Nature Neurosciencein 2012, showed that the anterior cingulate gyrus(ACCg) is an important nexus for the computation of shared experience and social reward. That same year researchers at Mount Sinai School of Medicine in New York published research in the journal Brainthat suggested that the anterior insular cortexis the activity centre of human empathy.
I find it both interesting and exciting that these studies link different brain regions to altruistic and compassionate behavior. “There are certain to be multiple mechanism that contribute to altruism, both in individuals and over evolutionary time,” added Huettel. This is the nature of the brain, whether we look at intelligence, motivation or physical characteristics. And I am convinced that we will someday find that many other areas—if not the entire area—of the brain are involved. Moreover, researchers have shown that engaging—or even witnessing—generous acts can reduce stress, increase immunity (e.g., increased antibody levels), and longevity.
Emiliana Simon-Thomas, science director for the Greater Good Science Center at the University of California, Berkeley, explains the chemical activity that happens in our heads when we commit acts of altruism. “There are multiple reward systems that have been tied to pleasurable feelings when people help others or contribute to the well being of the people around them,” she notes. These reward systems are comprised of three main chemicals that are released when we commit an act of kindness and feel pleasure: Dopamine, Oxytocin and Serotonin. According to Simon-Thomas, Dopamine is most closely related to hedonic pleasure — or pleasure derived from self; oxytocin is tied to more social pleasure — especially with regard to physical contact; and serotonin is implicated in a more broad mood state. “All three of these, again, are sort of intersecting and interacting, and depending on the context that you’re in, represent feelings of pleasure in different context,” she explains. “All these systems are activating and parallel, and sort of influencing one another as you go through life.” So when I do a good deed, I am rewarding myself with a cocktail of wonder drugs that please me and make me smile.
So, what I’ve known since I was a child is now proven: doing good deeds is mutually beneficial to the giver and the receiver.

Altruism in All Beings
The notion that all aspects of life on this planet—not just humanity—have the capacity to act altruistically remains controversial—even among professional scientists and researchers. We are not unique in experiencing or practicing altruism, in acting altruistically and benefiting from our own altruistic acts. It is however a matter of perspective, bias and open-mindedness. Many examples of altruistic behavior and empathy exist in the rest of the living world on our planet.
Nature’s Heroes
Scientists have been demonstrating for years that cooperation among organisms and communities and the act of pure altruism (not reciprocal altruism or kin/group selection) is, in fact, more common in Nature than most of us realize. Valid examples of true altruism in the wild in many species exist. The key here is “in the wild”—not in captivity, where inherent behavior is often modified (see my Alien Next Door article “The SamaritanParadox Revisited: The Karma Ran Over the Dogma”).
Despite the overwhelming evidence for altruism in every aspect of our world, some researchers continue to design experiments and then draw sweeping conclusions based on animals in captivity to suggest that only humanity possesses the ability to behave altruistically—and then again only by social-instruction (aka “the Selfish Gene” of Richard Dawkins vs. the “Social Gene” of Lynn Margulis).
Examples of altruism abound and range among mammals, birds, invertebrates and even Protista. Some examples include: dogs, cats, ducks, squirrels, wolves, mongooses, Meer cats, baboons, chimpanzees, vampire bats, dolphins, walruses, lemurs, African buffalo—to name a few.
de Waal explained that “evolution favors animals that assist each other if by doing so they achieve long-term benefits of greater value than the benefits derived from going it alone and competing with others” (de Waal 2006). The prevalent phenomenon of altruism is Nature’s answer to the Prisoner’s Dilemma. “Empathy evolved in animals as the main … mechanism for [individually] directed altruism,” said deWaal. And it is empathy—not self-interest—that “causes altruism to be dispensed in accordance with predictions from kin selection and reciprocal altruism theory.” deWaal further proposed that the scientific community has become polarized between evolutionary biologists on the one side, and, on the other, a discrete group of economists and anthropologists that “has invested heavily in the idea of strong reciprocity,” which demands discontinuity between humans and all other animals.
“One of the most striking consequences of the study of animal behavior,” says anthropologist Robert Sapolsky, “is the rethinking … of what it is to be human.” He notes that, “a number of realms, traditionally thought to define our humanity, have now been shown to be shared, at least partially, with nonhuman species.” (Sapolsky 2006). This makes some of us uncomfortable. To some, it threatens to make us less special. The corollary is that this demonstrates that we possess intrinsic virtue, not something “painted” on through cultural teaching or diligent personal effort. Of course, it also means that all other beings possess intrinsic value too. In the final analysis, what we generally “know” is colored by what we believe and want to continue believing.

Universal Altruism and Gaia
What does all this mean? Does the very existence of altruism demonstrate the connectivity of all life on Earth? Let’s not stop there. Does the grace of altruism reflect a fractal cosmos imbued with meaning and intent? Was it the grace of altruism that allowed it all to happen in the first place? Don’t we all come from grace?
Despite struggles with acceptance for some of us, we are emerging enlightened to the fractal existence of grace and altruism embedded in the very nature and intentions of our universe.
I come full circle to my book Darwin’s Paradox, a tale of fractal intelligence and universal cooperation. A tale of emerging awareness of Self and Other as One…Evolution through cooperation… Creative DNA…Manifestation through thought and intent…Self-organization and synchronicity…A hero’s journey…and coming Home…
In this season of gratitude, we celebrate altruism in giving and in receiving graciously.
Merry Christmas!
