Meditation

About keeping oneself mentally healthy.

I follow the website The Conversation and read most of their posts on a very regular basis. Back in May they published the following. It caught my eye because my own mental health is drifting downwards, or so it seems, due to age, I shall be 80 in November, 2024, plus a couple of brain bleedings that occurred in 2017 that were attended to by the Regional Trauma Center in Eugene.

I then had two sub-durnal (sp?) operations overnight before being put onto the ICU ward. The lead surgeon explained that I was within 24 hours of dying! As in if I had not gone back to hospital.

I find that difficult to realise that it was 6 years ago! Anyway, to the post published by The Conversation.

Mindfulness, meditation and self-compassion – a clinical psychologist explains how these science-backed practices can improve mental health

Mindfulness and self-compassion are now buzzwords for self-improvement. But in fact, a growing body of research shows these practices can lead to real mental health benefits. This research – ongoing, voluminous and worldwide – clearly shows how and why these two practices work.

One effective way to cultivate mindfulness and self-compassion is through meditation.

For more than 20 years, as a clinical psychologist, research scientist and educator, I taught meditation to students and clinical patients and took a deep dive into the research literature. My recent book, “The Self-Talk Workout: Six Science-Backed Strategies to Dissolve Self-Criticism and Transform the Voice in Your Head,” highlights much of that research.

I learned even more when I evaluated mental health programs and psychology classes that train participants in mindfulness and compassion-based techniques.

Defining mindfulness and self-compassion

Mindfulness means purposefully paying attention to the present moment with an attitude of interest or curiosity rather than judgment.

Self-compassion involves being kind and understanding toward yourself, even during moments of suffering or failure.

Both are associated with greater well-being.

But don’t confuse self-compassion with self-esteem or self-centeredness, or assume that it somehow lowers your standards, motivation or productivity. Instead, research shows that self-compassion is linked with greater motivation, less procrastination and better relationships.

Could mindfulness meditation be the next public health revolution?

Be patient when starting a meditation practice

I didn’t like meditation – the specific practice sessions that train mindfulness and self-compassion – the first time I tried it as a college student in the late ‘90s. I felt like a failure when my mind wandered, and I interpreted that as a sign that I couldn’t do it.

In both my own and others’ meditation practices, I’ve noticed that the beginning is often rocky and full of doubt, resistance and distraction.

But what seem like impediments can actually enhance meditation practice, because the mental work of handling them builds strength.

For the first six months I meditated, my body and mind were restless. I wanted to get up and do other tasks. But I didn’t. Eventually it became easier to notice my urges and thoughts without acting upon them. I didn’t get as upset with myself.

After about a year of consistent meditation, my mind seemed more organized and controllable; it no longer got stuck in self-critical loops. I felt a sense of kindness or friendliness toward myself in everyday moments, as well as during joyful or difficult experiences. I enjoyed ordinary activities more, such as walking or cleaning.

It took a while to understand that anytime you sit down and try to meditate, that’s meditation. It is a mental process, rather than a destination.

How meditation works on the mind

Just having a general intention to be more mindful or self-compassionate is unlikely to work.

Most programs shown to make meaningful differences involve at least seven sessions. Studies show these repeated workouts improve attention skills and decrease rumination, or repeated negative thinking.

They also lessen self-criticism, which is linked to numerous mental health difficulties, including depression, anxiety, eating disorders, self-harm and post-traumatic stress disorder.

Meditation is not just about sustaining your attention – it’s also about shifting and returning your focus after the distraction. The act of shifting and refocusing cultivates attention skills and decreases rumination.

Trying repeatedly to refrain from self-judgment during the session will train your mind to be less self-critical.

An interconnected group of brain regions called the default mode network is strikingly affected by meditation. Much of this network’s activity reflects repetitive thinking, such as a rehash of a decadeslong tension with your sister. It’s most prominent when you’re not doing much of anything. Activity of the default mode network is related to rumination, unhappiness and depression.

Research shows that just one month of meditation reduces the noise of the default mode network. The type of meditation practice doesn’t seem to matter.

Don’t be discouraged if your mind wanders as you meditate.

Establishing the formal practice

A common misconception about mindfulness is that it’s simply a way to relax or clear the mind. Rather, it means intentionally paying attention to your experiences in a nonjudgmental way.

Consider meditation the formal part of your practice – that is, setting aside a time to work on specific mindfulness and self-compassion techniques.

Cultivating mindfulness with meditation often involves focusing on paying attention to the breath. A common way to start practice is to sit in a comfortable place and bring attention to your breathing, wherever you feel it most strongly.

At some point, probably after a breath or two, your mind will wander to another thought or feeling. As soon as you notice that, you can bring your attention back to the breath and try not to judge yourself for losing focus for five to 10 minutes.

When I was just getting started meditating, I would have to redirect my attention dozens or hundreds of times in a 20-to-30-minute session. Counting 10 breaths, and then another 10, and so on, helped me link my mind to the task of paying attention to my breathing.

The most well-established technique for cultivating self-compassion is called loving-kindness meditation. To practice, you can find a comfortable position, and for at least five minutes, internally repeat phrases such as, “May I be safe. May I be happy. May I be healthy. May I live with ease.”

When your attention wanders, you can bring it back with as little self-judgment as possible and continue repeating the phrases. Then, if you like, offer the same well wishes to other people or to all beings.

Every time you return your focus to your practice without judging, you’re flexing your mental awareness, because you noticed your mind wandered. You also improve your capacity to shift attention, a valuable anti-rumination skill, and your nonjudgment, an antidote to self-criticism.

These practices work. Studies show that brain activity during meditation results in less self-judgment, depression and anxiety and results in less rumination.

Mindfulness also occurs when you tune into present-moment sensations, such as tasting your food or washing the dishes.

An ongoing routine of formal and informal practice can transform your thinking. And again, doing it once in a while won’t help as much. It’s like situps: A single situp isn’t likely to strengthen your abdominal muscles, but doing several sets each day will.

When thoughts pop up during meditation, no worries. Just start again … and again … and again.

Meditation reduces self-criticism

Studies show that mindfulness meditation and loving-kindness meditation reduce self-criticism, which leads to better mental health, including lower levels of depression, anxiety and PTSD. After an eight-week mindfulness program, participants experienced less self-judgment. These changes were linked with decreases in depression and anxiety.

One final point: Beginning meditators may find that self-criticism gets worse before it gets better.

After years or decades of habitual self-judgment, people often judge themselves harshly about losing focus during meditation. But once students get through the first few weeks of practice, the self-judgment begins to abate, both about meditation and about oneself in general.

As one of my students recently said after several weeks of mindfulness meditation: “I am more stable, more able to detach from unhelpful thoughts and can do all of this while being a little more compassionate and loving toward myself.”

I do not meditate; have never done so.

In reading this article I think I should try and find a way to start the process. There are a great number of articles and websites. I will share my journey with you.

Time will tell!

There’s more to water than one might think.

This post attracted me and I wanted to share it with you.

Here in Oregon we are lucky because the ground water is of a high quality and there is plenty of it. At home we drink our water straight from our well without any filtering or chlorination. Have been doing that ever since we moved in back in 2012.

But water is a much deeper subject than I tend to think of and this article is an in-depth review of the topic. It is an article from The Conversation.

Water in space – a ‘Goldilocks’ star reveals previously hidden step in how water gets to planets like Earth

Without water, life on Earth could not exist as it does today. Understanding the history of water in the universe is critical to understanding how planets like Earth come to be.

Astronomers typically refer to the journey water takes from its formation as individual molecules in space to its resting place on the surfaces of planets as “the water trail.” The trail starts in the interstellar medium with hydrogen and oxygen gas and ends with oceans and ice caps on planets, with icy moons orbiting gas giants and icy comets and asteroids that orbit stars. The beginnings and ends of this trail are easy to see, but the middle has remained a mystery.

I am an astronomer who studies the formation of stars and planets using observations from radio and infrared telescopes. In a new paper, my colleagues and I describe the first measurements ever made of this previously hidden middle part of the water trail and what these findings mean for the water found on planets like Earth.

How planets are formed

The formation of stars and planets is intertwined. The so-called “emptiness of space” – or the interstellar medium – in fact contains large amounts of gaseous hydrogen, smaller amounts of other gasses and grains of dust. Due to gravity, some pockets of the interstellar medium will become more dense as particles attract each other and form clouds. As the density of these clouds increases, atoms begin to collide more frequently and form larger molecules, including water that forms on dust grains and coats the dust in ice.

Stars begin to form when parts of the collapsing cloud reach a certain density and heat up enough to start fusing hydrogen atoms together. Since only a small fraction of the gas initially collapses into the newborn protostar, the rest of the gas and dust forms a flattened disk of material circling around the spinning, newborn star. Astronomers call this a proto-planetary disk.

As icy dust particles collide with each other inside a proto-planetary disk, they begin to clump together. The process continues and eventually forms the familiar objects of space like asteroids, comets, rocky planets like Earth and gas giants like Jupiter or Saturn.

Two theories for the source of water

There are two potential pathways that water in our solar system could have taken. The first, called chemical inheritance, is when the water molecules originally formed in the interstellar medium are delivered to proto-planetary disks and all the bodies they create without going through any changes.

The second theory is called chemical reset. In this process, the heat from the formation of the proto-planetary disk and newborn star breaks apart water molecules, which then reform once the proto-planetary disk cools.

To test these theories, astronomers like me look at the ratio between normal water and a special kind of water called semi-heavy water. Water is normally made of two hydrogen atoms and one oxygen atom. Semi-heavy water is made of one oxygen atom, one hydrogen atom and one atom of deuterium – a heavier isotope of hydrogen with an extra neutron in its nucleus.

The ratio of semi-heavy to normal water is a guiding light on the water trail – measuring the ratio can tell astronomers a lot about the source of water. Chemical models and experiments have shown that about 1,000 times more semi-heavy water will be produced in the cold interstellar medium than in the conditions of a protoplanetary disk.

This difference means that by measuring the ratio of semi-heavy to normal water in a place, astronomers can tell whether that water went through the chemical inheritance or chemical reset pathway.

Measuring water during the formation of a planet

Comets have a ratio of semi-heavy to normal water almost perfectly in line with chemical inheritance, meaning the water hasn’t undergone a major chemical change since it was first created in space. Earth’s ratio sits somewhere in between the inheritance and reset ratio, making it unclear where the water came from.

To truly determine where the water on planets comes from, astronomers needed to find a goldilocks proto-planetary disk – one that is just the right temperature and size to allow observations of water. Doing so has proved to be incredibly difficult. It is possible to detect semi-heavy and normal water when water is a gas; unfortunately for astronomers, the vast majority of proto-plantary disks are very cold and contain mostly ice, and it is nearly impossible to measure water ratios from ice at interstellar distances.

A breakthrough came in 2016, when my colleagues and I were studying proto-planetary disks around a rare type of young star called FU Orionis stars. Most young stars consume matter from the proto-planetary disks around them. FU Orionis stars are unique because they consume matter about 100 times faster than typical young stars and, as a result, emit hundreds of times more energy. Due to this higher energy output, the proto-planetary disks around FU Orionis stars are heated to much higher temperatures, turning ice into water vapor out to large distances from the star.

Using the Atacama Large Millimeter/submillimeter Array, a powerful radio telescope in northern Chile, we discovered a large, warm proto-planetary disk around the Sunlike young star V883 Ori, about 1,300 light years from Earth in the constellation Orion.

V883 Ori emits 200 times more energy than the Sun, and my colleagues and I recognized that it was an ideal candidate to observe the semi-heavy to normal water ratio.

Completing the water trail

In 2021, the Atacama Large Millimeter/submillimeter Array took measurements of V883 Ori for six hours. The data revealed a strong signature of semi-heavy and normal water coming from V883 Ori’s proto-planetary disk. We measured the ratio of semi-heavy to normal water and found that the ratio was very similar to ratios found in comets as well as the ratios found in younger protostar systems.

These results fill in the gap of the water trail forging a direct link between water in the interstellar medium, protostars, proto-planetary disks and planets like Earth through the process of inheritance, not chemical reset.

The new results show definitively that a substantial portion of the water on Earth most likely formed billions of years ago, before the Sun had even ignited. Confirming this missing piece of water’s path through the universe offers clues to origins of water on Earth. Scientists have previously suggested that most water on Earth came from comets impacting the planet. The fact that Earth has less semi-heavy water than comets and V883 Ori, but more than chemical reset theory would produce, means that water on Earth likely came from more than one source.

Now this was a long article and I hope some of you stayed with John’s piece until the very end.

It really shows how the water trail is a much greater and longer journey than I assumed.

The relationship between us and wild animals.

In this particular case looking at the wolf.

So many times a particular article from a website that allows republishing is not only a good and relevant article but also is a quick way of me publishing a post when, as I was yesterday, a bit pressed for time.

So here is that article from The Conversation.

Wolf restoration in Colorado shows how humans are rethinking their relationships with wild animals

From sports to pop culture, there are few themes more appealing than a good comeback. They happen in nature, too. Even with the Earth losing species at a historic rate, some animals have defied the trend toward extinction and started refilling their old ecological niches.

I’m a philosopher based in Montana and specialize in environmental ethics. For my new book, “Tenacious Beasts: Wildlife Recoveries That Change How We Think About Animals,” I spent three years looking at wildlife comebacks across North America and Europe and considering the lessons they offer. In every case, whether the returnee is a bison, humpback whale, beaver, salmon, sea otter or wolf, the recovery has created an opportunity for humans to profoundly rethink how we live with these animals.

One place to see the rethink in action is Colorado, where voters approved a ballot measure in 2020 mandating the reintroduction of gray wolves west of the Continental Divide. Colorado’s Parks and Wildlife Agency has released a draft plan that calls for moving 30 to 50 gray wolves from other Rocky Mountain states into northwest Colorado over five years, starting in 2024.

Aldo Leopold, the famed conservationist and professor of game management at the University of Wisconsin, believed that moral beliefs evolve over time to become more inclusive of the natural world. And what’s happening in Colorado suggests Leopold was right. Human attitudes toward wolves have clearly evolved since the mid-1940s, when bounties, mass poisoning and trapping eradicated wolves from the state.

Recovering animals encounter a world that is markedly different from the one in which they declined, especially in terms of how people think about wildlife. Here are several reasons I see why societal attitudes toward wolves have changed. The importance of keystone species

Wolves released in northwest Colorado will wear GPS collars that enable wildlife managers to track them.

The idea that certain influential species, which ecologists call keystone species, can significantly alter the ecosystems around them first appeared in scientific literature in 1974. Bison, sea otters, beavers, elephants and wolves all exert this power. One way in which wolves wield influence is by preying on coyotes, which produces ripple effects across the system. Fewer coyotes means more rodents, which in turn means better hunting success for birds of prey.

Wolves also cause nervous behaviors among their prey. Some scientists believe that newly returned predators create a “landscape of fear” among prey species – a term that isn’t positive or negative, just descriptive. This idea has shifted thinking about predators. For example, elk avoid some areas when wolves are around, resulting in ecological changes that cascade down from the top. Vegetation can recover, which in turn may benefit other species.

Insights into pack dynamics

Animal behavioral science research has provided pointers for better wolf management. Studies show that wolf packs are less likely to prey on livestock if their social structure remains intact. This means that ranchers and wildlife managers should take care not to remove the pack’s breeding pair when problems occur. Doing so can fragment the pack and send dispersing wolves into new territories.

Wildlife agencies also have access to years of data from close observation of wolf behavior in places like Yellowstone National Park, where wolves were reintroduced starting in 1995. This research offers insights into the wolf’s intelligence and social complexity. All of this information helps to show how people can live successfully alongside them.

Predators provide economic value

Research has also demonstrated that wolves provide economic benefits to states and communities. Wisconsin researchers discovered that changes in deer behavior due to the presence of wolves have saved millions of dollars in avoided deer collisions with cars. These savings far exceed what it costs the state to manage wolves.

Wolf recovery has been shown to be a net economic benefit in areas of the U.S. West where they have returned. The dollars they attract from wolf-watchers, photographers and foreign visitors have provided a valuable new income stream in many communities.

Predators do kill livestock, but improved tracking has helped to put these losses in perspective. Montana Board of Livestock numbers show that wolves, grizzly bears and mountain lions caused the loss of 131 cattle and 137 sheep in the state in 2022. This is from a total of 2,200,000 cattle and 190,000 sheep. Of the 131 cattle, 36 were confirmed to be taken by wolves – 0.0016% of the statewide herd.

According to the U.S. Department of Agriculture, dogs, foxes and coyotes in Montana all killed more sheep and lambs than wolves did in 2020. Even eagles were three times more deadly to sheep and lambs than wolves were.

Actual costs to ranchers are certainly higher than these numbers suggest. The presence of wolves causes livestock to lose weight because the animals feed more nervously when wolves are around. Ranchers also lose sleep as they worry about wolves attacking their livestock and guard dogs. And clearly, low statewide kills are small comfort to a rancher who loses a dozen or more animals in one year. Margins are always tight in the livestock business.

A northern Colorado rancher discusses options for protecting his cattle from wolves, which already are naturally present in the state.

What’s more, predators’ economic impacts don’t end with ranching. In Colorado, for example, elk numbers are likely to decline after wolves are reintroduced. This may affect state wildlife agency budgets that rely on license fees from elk hunters. It may also affect hunting outfitters’ incomes.

In my view, voters who supported bringing wolves back to Colorado should remain deeply aware of the full distribution of costs and support proactive compensation schemes for losses. They should be mindful that support for wolf reintroduction varies drastically between urban and rural communities and should insist that effective mechanisms are in place ahead of time to ensure fair sharing of the economic burdens that wolves generate.

A new ethical playing field

Despite these complexities, the idea of the “big bad wolf” clearly no longer dominates Americans’ thinking. And the wolf is not alone. Social acceptance of many other wildlife species is also increasing. For example, a 2023 study found that between 80% and 90% of Montanans believed grizzly bears – which are recovering and expanding their presence there – have a right to exist.

Aldo Leopold famously claimed to have experienced an epiphany when he shot a wolf in New Mexico in the 1920s and saw “a fierce green fire” dying in her eyes. In reality, his attitude took several more decades to change. Humans may have an ingrained evolutionary disposition to fear carnivorous predators like wolves, but the change ended up being real for Leopold, and it lasted.

Leopold, who died in 1948, did not live to see many wildlife species recover, but I believe he would have regarded what’s happening now as an opportunity for Americans’ moral growth. Because Leopold knew that ethics, like animals, are always evolving.

The clue to making us human

A really fascinating article from The Conversation on Imagination.

Imagination makes us human – this unique ability to envision what doesn’t exist has a long evolutionary history

You can easily picture yourself riding a bicycle across the sky even though that’s not something that can actually happen. You can envision yourself doing something you’ve never done before – like water skiing – and maybe even imagine a better way to do it than anyone else.

Imagination involves creating a mental image of something that is not present for your senses to detect, or even something that isn’t out there in reality somewhere. Imagination is one of the key abilities that make us human. But where did it come from?

I’m a neuroscientist who studies how children acquire imagination. I’m especially interested in the neurological mechanisms of imagination. Once we identify what brain structures and connections are necessary to mentally construct new objects and scenes, scientists like me can look back over the course of evolution to see when these brain areas emerged – and potentially gave birth to the first kinds of imagination.

From bacteria to mammals

After life emerged on Earth around 3.4 billion years ago, organisms gradually became more complex. Around 700 million years ago, neurons organized into simple neural nets that then evolved into the brain and spinal cord around 525 million years ago.

Eventually dinosaurs evolved around 240 million years ago, with mammals emerging a few million years later. While they shared the landscape, dinosaurs were very good at catching and eating small, furry mammals. Dinosaurs were cold-blooded, though, and, like modern cold-blooded reptiles, could only move and hunt effectively during the daytime when it was warm. To avoid predation by dinosaurs, mammals stumbled upon a solution: hide underground during the daytime.

Not much food, though, grows underground. To eat, mammals had to travel above the ground – but the safest time to forage was at night, when dinosaurs were less of a threat. Evolving to be warm-blooded meant mammals could move at night. That solution came with a trade-off, though: Mammals had to eat a lot more food than dinosaurs per unit of weight in order to maintain their high metabolism and to support their constant inner body temperature around 99 degrees Fahrenheit (37 degrees Celsius).

Our mammalian ancestors had to find 10 times more food during their short waking time, and they had to find it in the dark of night. How did they accomplish this task?

To optimize their foraging, mammals developed a new system to efficiently memorize places where they’d found food: linking the part of the brain that records sensory aspects of the landscape – how a place looks or smells – to the part of the brain that controls navigation. They encoded features of the landscape in the neocortex, the outermost layer of the brain. They encoded navigation in the entorhinal cortex. And the whole system was interconnected by the brain structure called the hippocampus. Humans still use this memory system for remembering objects and past events, such as your car and where you parked it.

Groups of neurons in the neocortex encode these memories of objects and past events. Remembering a thing or an episode reactivates the same neurons that initially encoded it. All mammals likely can recall and re-experience previously encoded objects and events by reactivating these groups of neurons. This neocortex-hippocampus-based memory system that evolved 200 million years ago became the first key step toward imagination.

The next building block is the capability to construct a “memory” that hasn’t really happened.

Involuntary made-up ‘memories’

The simplest form of imagining new objects and scenes happens in dreams. These vivid, bizarre involuntary fantasies are associated in people with the rapid eye movement (REM) stage of sleep.

Scientists hypothesize that species whose rest includes periods of REM sleep also experience dreams. Marsupial and placental mammals do have REM sleep, but the egg-laying mammal the echidna does not, suggesting that this stage of the sleep cycle evolved after these evolutionary lines diverged 140 million years ago. In fact, recording from specialized neurons in the brain called place cells demonstrated that animals can “dream” of going places they’ve never visited before.

In humans, solutions found during dreaming can help solve problems. There are numerous examples of scientific and engineering solutions spontaneously visualized during sleep.

The neuroscientist Otto Loewi dreamed of an experiment that proved nerve impulses are transmitted chemically. He immediately went to his lab to perform the experiment – later receiving the Nobel Prize for this discovery.

Elias Howe, the inventor of the first sewing machine, claimed that the main innovation, placing the thread hole near the tip of the needle, came to him in a dream.

Dmitri Mendeleev described seeing in a dream “a table where all the elements fell into place as required. Awakening, I immediately wrote it down on a piece of paper.” And that was the periodic table.

These discoveries were enabled by the same mechanism of involuntary imagination first acquired by mammals 140 million years ago.

Imagining on purpose

The difference between voluntary imagination and involuntary imagination is analogous to the difference between voluntary muscle control and muscle spasm. Voluntary muscle control allows people to deliberately combine muscle movements. Spasm occurs spontaneously and cannot be controlled.

Similarly, voluntary imagination allows people to deliberately combine thoughts. When asked to mentally combine two identical right triangles along their long edges, or hypotenuses, you envision a square. When asked to mentally cut a round pizza by two perpendicular lines, you visualize four identical slices.

This deliberate, responsive and reliable capacity to combine and recombine mental objects is called prefrontal synthesis. It relies on the ability of the prefrontal cortex located at the very front of the brain to control the rest of the neocortex.

When did our species acquire the ability of prefrontal synthesis? Every artifact dated before 70,000 years ago could have been made by a creator who lacked this ability. On the other hand, starting about that time there are various archeological artifacts unambiguously indicating its presence: composite figurative objects, such as lion-man; bone needles with an eye; bows and arrows; musical instruments; constructed dwellings; adorned burials suggesting the beliefs in afterlife, and many more.

Multiple types of archaeological artifacts unambiguously associated with prefrontal synthesis appear simultaneously around 65,000 years ago in multiple geographical locations. This abrupt change in imagination has been characterized by historian Yuval Harari as the “cognitive revolution.” Notably, it approximately coincides with the largest Homo sapiens‘ migration out of Africa.

Genetic analyses suggest that a few individuals acquired this prefrontal synthesis ability and then spread their genes far and wide by eliminating other contemporaneous males with the use of an imagination-enabeled strategy and newly developed weapons.

So it’s been a journey of many millions of years of evolution for our species to become equipped with imagination. Most nonhuman mammals have potential for imagining what doesn’t exist or hasn’t happened involuntarily during REM sleep; only humans can voluntarily conjure new objects and events in our minds using prefrontal synthesis.

Plastics in the ocean

A fascinating insight into recovered plastic.

Like so many others we do our little bit regarding plastic but do not properly think about the issue. I have to admit that I am not even sure if all plastics are harmful or just some.

But I comprehend art!

That is why I am republishing, with permission, this article from The Conversation.

My art uses plastic recovered from beaches around the world to understand how our consumer society is transforming the ocean

I am obsessed with plastic objects. I harvest them from the ocean for the stories they hold and to mitigate their ability to harm. Each object has the potential to be a message from the sea – a poem, a cipher, a metaphor, a warning.

My work collecting and photographing ocean plastic and turning it into art began with an epiphany in 2005, on a far-flung beach at the southern tip of the Big Island of Hawaii. At the edge of a black lava beach pounded by surf, I encountered multitudes upon multitudes of plastic objects that the angry ocean was vomiting onto the rocky shore.

I could see that somehow, impossibly, humans had permeated the ocean with plastic waste. Its alien presence was so enormous that it had reached this most isolated point of land in the immense Pacific Ocean. I felt I was witness to an unspeakable crime against nature, and needed to document it and bring back evidence.

I began cleaning the beach, hauling away weathered and misshapen plastic debris – known and unknown objects, hidden parts of a world of things I had never seen before, and enormous whalelike colored entanglements of nets and ropes.

I returned to that site again and again, gathering material evidence to study its volume and how it had been deposited, trying to understand the immensity it represented. In 2006, I formed the Drifters Project, a collaborative global entity to highlight these vagrant, translocational plastics and recruit others to investigate and mitigate ocean plastics’ impact.

My new book, “Ocean Gleaning,” tracks 17 years of my art and research around the world through the Drifters Project. It reveals specimens of striking artifacts harvested from the sea – objects that once were utilitarian, but have been changed by their oceanic voyages and come back as messages from the ocean.

Living in a plastic age

I grew up in what some now deem the age of plastic. Though it’s not the only modern material invention, plastic has had the most unforeseen consequences.

My father was a biochemist at the chemical company Union Carbide when I was a child in New Jersey. He played golf with an actor who portrayed “The Man from Glad,” a Get Smart-styled agent who rescued flustered housewives in TV commercials from inferior brands of plastic wrap that snarled and tangled. My father brought home souvenir pins of Union Carbide’s hexagonal logo, based on the carbon molecule, and figurine pencil holders of “TERGIE,” the company’s blobby turquoise mascot.

On the 2013 Gyre Expedition, Pam Longobardi traveled with a team of scientists, artists and policymakers to investigate and remove tons of oceanic plastic washing out of great gyres, or currents, in the Pacific Ocean, and make art from it.

Today I see plastic as a zombie material that haunts the ocean. It is made from petroleum, the decayed and transformed life forms of the past. Drifting at sea, it “lives” again as it gathers a biological slime of algae and protozoans, which become attachment sites for larger organisms.

When seabirds, fish and sea turtles mistake this living encrustation for food and eat it, plastic and all, the chemical load lives on in their digestive tracts. Their body tissues absorb chemicals from the plastic, which remain undigested in their stomachs, often ultimately killing them.

The forensics of plastic

I see plastic objects as the cultural archaeology of our time – relics of global late-capitalist consumer society that mirror our desires, wishes, hubris and ingenuity. They become transformed as they leave the quotidian world and collide with nature. By regurgitating them ashore or jamming them into sea caves, the ocean is communicating with us through materials of our own making. Some seem eerily familiar; others are totally alien.

A person engaging in ocean gleaning acts as a detective and a beacon, hunting for the forensics of this crime against the natural world and shining the light of interrogation on it. By searching for ocean plastic in a state of open receptiveness, a gleaner like me can find symbols of pop culture, religion, war, humor, irony and sorrow.

In keeping with the drifting journeys of these material artifacts, I prefer using them in a transitive form as installations. All of these works can be dismantled and reconfigured, although plastic materials are nearly impossible to recycle. I display some objects as specimens on steel pins, and wire others together to form large-scale sculptures.

I am interested in ocean plastic in particular because of what it reveals about us as humans in a global culture, and about the ocean as a cultural space and a giant dynamic engine of life and change. Because ocean plastic visibly shows nature’s attempts to reabsorb and regurgitate it, it has profound stories to tell.

I believe humankind is at a crossroads with regards to the future. The ocean is asking us to pay attention. Paying attention is an act of giving, and in the case of plastic pollution, it is also an act of taking: Taking plastic out of your daily life. Taking plastic out of the environment. And taking, and spreading, the message that the ocean is laying out before our eyes.

Pam at one point describes the ocean plastic”… because of what it reveals about us as humans in a global culture, and about the ocean as a cultural space and a giant dynamic engine of life and change …”. It raises questions that I can only ponder the answer. Ultimately, are there too many inhabitants on this planet? What does the next generation think? Is there an answer?

Burt Bacharach remembered

So many tuneful memories.

I grew up with the songs of Burt Bacharach in my heart, my mind and my ears. He was born on May 12, 1928 and lived until quite recently; namely the 8th February, 2023. This may be Valentine’s Day for 2023 but I think the obituary of Bacharach comes first.

The Conversation had a brilliant item on him, published on February 10th and I am going to republish that piece now.

Burt Bacharach mastered the art of the perfect pop song – and that ain’t easy

Gena R. Greher, UMass Lowell

Easy on the ear, perhaps. But the label of “easy listening” often attached to the songs of Burt Bacharach belies the mastery of his talent in crafting perfect moments in music.

Yes, Bacharach’s back catalog is filled with memorable, catchy melodies – whether they were written with longtime partner and lyricist Hal David, former wife Carole Bayer Sager or in collaboration with more contemporary artists such as Elvis Costello, Adele and Dr. Dre.

But there is a harmonic and rhythmic complexity to his music that elevates it above the sweet, often saccharine arrangements that can typify easy listening. It is full of influences from jazz chord structures and progressions, as well as rhythms.

It is why Bacharach, who died on Feb. 8, 2023, at the age of 94, appealed to generations of listeners, as well as the diverse pool of singers who chose to work with him.

Cross-generational appeal

Bacharach began his long songwriting career in the 1950s, but it was the following decade that saw him come to prominence with a series of hit songs.

But with the 1960s as a backdrop – a time of immense innovation in popular music – Bacharach may not have been taken as seriously as many of his contemporaries. It was a time when rock ‘n’ roll and the British Invasion were at the forefront, with rhythm and blues, protest music and folk rock finding their way on the musical landscape.

While Bacharach’s musical counterparts were writing and performing music that responded to and reflected the political, social and cultural upheavals that defined the era, Bacharach and David’s songs focused on different themes: Theirs was music that dealt with relationships and matters of the heart.

They also stood apart from other notable songwriting partners of the age – Lennon and McCartney, Jagger and Richards, for example – in that the songs were written for others to perform. In that way, they were a throwback to an earlier age of popular music, when the likes of Rodgers and Hart provided hit after hit for a roster of singers.

Indeed, they were a late product of Tin Pan Alley – the music industry centered around midtown Manhattan. Bacharach met David in 1957 in the storied Brill Building in New York City – a place where a young songwriter could perhaps catch a break.

Not long after they began working together, Bacharach came across a young backup singer at a recording session who seemed to have promise. The first single he produced with her, “Don’t Make Me Over,” was the first of 38 songs he and David produced with Dionne Warwick.

Her warm tones and fluid phrasing made Warwick’s voice the perfect accompaniment to Bacharach’s music.

But she was one of many collaborators. Some, like Warwick, were plucked from relative obscurity. Others, like Perry Como, were already established singers.

The list of artists who found success with Bacharach songs in that era is astonishing: Aretha Franklin, The Carpenters, Dusty Springfield, Tom Jones and The 5th Dimension, to name just a few.

Through collaborators, Bacharach’s music was able to reach a fairly diverse audience. The songs were so well written that they could easily be reworked into different genres, and break the confines of “easy listening” – a genre often maligned as unhip. In the hands of Isaac Hayes, the sweet refrains of “Walk on By” becomes a psychedelic funk classic. Years later, The White Stripes transformed “I Just Don’t Know What To Do With Myself” into a stripped-down, guitar-heavy slice of rock.

Froms Oscars to revivals

The music of David and Bacharach also worked on a different level – as the background to movie soundtracks. The 1966 Michael Caine film “Alfie” is perhaps equally known today for the title track, with versions by Cher, Warwick and British singer Cilla Black all becoming hits on the back of the film.

In 1969, Bacharach and David’s “Raindrops Keep Falling on My Head,” sung by B.J. Thomas in the western “Butch Cassidy and the Sundance Kid,” won the Academy Award for best original song. Bacharach also won the Oscar for best original score.

Adding to success on the charts and on screen, Bacharach also won acclaim for his work on Broadway. The 1968 show “Promises, Promises” was groundbreaking in its use of amplification in the orchestra, which included a rock band. The show contained a number of songs that topped the charts, most notably Warwick’s version of the show-stopping “I’ll Never Fall in Love Again.”

In an NPR “Fresh Air” interview in 2010 – when the musical was being revived on Broadway – Bacharach discusses the number of rhythmic meter changes in the title song, “Promises, Promises,” and the difficulties these rhythmic changes presented for singers and musicians in the show.

The interview is also notable in that it reunited him with David – the two had a much publicized split in 1973 after working on a failed movie. The breakdown of their successful musical partnership saw Bacharach lose interest in writing music for a spell, and affected his relationship with Warwick.

This was eventually resolved with her recording of one of Bacharach’s most memorable songs, 1985’s “That’s What Friends are For,” written with his then-wife, Carole Bayer Sager. Though the song had been first recorded by Rod Stewart for the film “Night Shift,” the Warwick & Friends’ version – the friends being none other than Elton John, Gladys Knight and Stevie Wonder – is the one that became a hit and helped revive Bacharach’s career.

Though best known for the songs he wrote in the 1960s through the 1980s, Bacharach continued to write music into his old age, collaborating with Elvis Costello, Adele and Dr. Dre.

You may have noticed the sheer number – and range – of artists Bacharach worked with. It speaks to the quality and endurance of his output. Yes, he will be remembered by some as the writer of exemplary “easy listening” songs. But Burt Bacharach’s legacy will prove that he was so much more.

How do the eyes of dogs see?

It is the last day of January and we have a post about dogs today.

I found all the non-doggie articles a bit depressing and this item seemed a delightful alternative. It is from the Curious Kids section of The Conversation but, to my mind, of interest to adults as well.

Do dogs really see in just black and white? – Oscar V., age 9, Somerville, Massachusetts

Dogs definitely see the world differently than people do, but it’s a myth that their view is just black, white and grim shades of gray.

While most people see a full spectrum of colors from red to violet, dogs lack some of the light receptors in their eyes that allow human beings to see certain colors, particularly in the red and green range. But canines can still see yellow and blue.

Different wavelengths of light register as different colors in an animal’s visual system. Top is the human view; bottom is a dog’s eye view. Top: iStock/Getty Images Plus via Getty Images. Bottom: As processed by András Péter’s Dog Vision Image Processing Tool

What you see as red or orange, to a dog may just be another shade of tan. To my dog, Sparky, a bright orange ball lying in the green grass may look like a tan ball in another shade of tan grass. But his bright blue ball will look similar to both of us. An online image processing tool lets you see for yourself what a particular picture looks like to your pet.

Animals can’t use spoken language to describe what they see, but researchers easily trained dogs to touch a lit-up color disc with their nose to get a treat. Then they trained the dogs to touch a disc that was a different color than some others. When the well-trained dogs couldn’t figure out which disc to press, the scientists knew that they couldn’t see the differences in color. These experiments showed that dogs could see only yellow and blue.

In the back of our eyeballs, human beings’ retinas contain three types of special cone-shaped cells that are responsible for all the colors we can see. When scientists used a technique called electroretinography to measure the way dogs’ eyes react to light, they found that canines have fewer kinds of these cone cells. Compared to people’s three kinds, dogs only have two types of cone receptors.

Not only can dogs see fewer colors than we do, they probably don’t see as clearly as we do either. Tests show that both the structure and function of the dog eye leads them to see things at a distance as more blurry. While we think of perfect vision in humans as being 20/20, typical vision in dogs is probably closer to 20/75. This means that what a person with normal vision could see from 75 feet away, a dog would need to be just 20 feet away to see as clearly. Since dogs don’t read the newspaper, their visual acuity probably doesn’t interfere with their way of life.

There’s likely a lot of difference in visual ability between breeds. Over the years, breeders have selected sight-hunting dogs like greyhounds to have better vision than dogs like bulldogs.

But that’s not the end of the story. While people have a tough time seeing clearly in dim light, scientists believe dogs can probably see as well at dusk or dawn as they can in the bright middle of the day. This is because compared to humans’, dog retinas have a higher percentage and type of another kind of visual receptor. Called rod cells because of their shape, they function better in low light than cone cells do.

Dogs also have a reflective tissue layer at the back of their eyes that helps them see in less light. This mirror-like tapetum lucidum collects and concentrates the available light to help them see when it’s dark. The tapetum lucidum is what gives dogs and other mammals that glowing eye reflection when caught in your headlights at night or when you try to take a flash photo.

Dogs share their type of vision with many other animals, including cats and foxes. Scientists think it’s important for these hunters to be able to detect the motion of their nocturnal prey, and that’s why their vision evolved in this way. As many mammals developed the ability to forage and hunt in twilight or dark conditions, they gave up the ability to see the variety of colors that most birds, reptiles and primates have. People didn’t evolve to be active all night, so we kept the color vision and better visual acuity.

Before you feel sorry that dogs aren’t able to see all the colors of the rainbow, keep in mind that some of their other senses are much more developed than yours. They can hear higher-pitched sounds from farther away, and their noses are much more powerful.

Even though Sparky might not be able to easily see that orange toy in the grass, he can certainly smell it and find it easily when he wants to.

ooOOoo

I don’t know about you but I found this most interesting and the last thing I would be described as is a kid!

In terms of our own dogs their ability to forage in the dark is quite amazing and, presumably, our dogs are quite typical of dogs in general.

Putting aside the pills!

A fascinating article presents an alternative.

There was a recent item on The Conversation that is being shared with you all today. It is about the role of meditation and mindfulness is keeping one healthy, and I sense this will be a popular article!

Meditation and mindfulness offer an abundance of health benefits and may be as effective as medication for treating certain conditions

By Hilary A. Marusak

Assistant Professor of Psychiatry and Behavioral Neurosciences, Wayne State University

Published January 12th, 2023

Many people look to diet trends or new exercise regimens – often with questionable benefit – to get a healthier start on the new year. But there is one strategy that’s been shown time and again to boost both mood and health: meditation.

In late 2022, a high-profile study made a splash when it claimed that meditation may work as well as a common drug named Lexapro for the treatment of anxiety. Over the past couple of decades, similar evidence has emerged about mindfulness and meditation’s broad array of health benefits, for purposes ranging from stress and pain reduction to depression treatments to boosting brain health and helping to manage excessive inflammation and long COVID-19.

Despite the mounting body of evidence showing the health benefits of meditation, it can be hard to weigh the science and to know how robust it is.

I am a neuroscientist studying the effects of stress and trauma on brain development in children and adolescents. I also study how mindfulness, meditation and exercise can positively affect brain development and mental health in youth.

I am very excited about how meditation can be used as a tool to provide powerful new insights into the ways the mind and brain work, and to fundamentally change a person’s outlook on life. And as a mental health researcher, I see the promise of meditation as a low- or no-cost, evidence-based tool to improve health that can be relatively easily integrated into daily life.

Meditation requires some training, discipline and practice – which are not always easy to come by. But with some specific tools and strategies, it can be accessible to everyone.

What are mindfulness and meditation?

There are many different types of meditation, and mindfulness is one of the most common. Fundamentally, mindfulness is a mental state that, according to Jon Kabat-Zinn a renowned expert in mindfulness-based practices, involves “awareness that arises through paying attention, on purpose, in the present moment, non-judgmentally.”

This means not ruminating about something that happened in the past or worrying about that to-do list. Being focused on the present, or living in the moment, has been shown to have a broad array of benefits, including elevating mood, reducing anxiety, lessening pain and potentially improving cognitive performance.

Mindfulness is a skill that can be practiced and cultivated over time. The goal is that, with repetition, the benefits of practicing mindfulness carry over into everyday life – when you aren’t actively meditating. For example, if you learn that you aren’t defined by an emotion that arises transiently, like anger, then it may be harder to stay angry for long.

The health benefits of meditation and other strategies aimed at stress reduction are thought to stem from increasing levels of overall mindfulness through practice. Elements of mindfulness are also present in practices like yoga, martial arts and dance that require focusing attention and discipline.

The vast body of evidence supporting the health benefits of meditation is too expansive to cover exhaustively. But the studies I reference below represent some of the top tier, or the highest-quality and most rigorous summaries of scientific data on the topic to date. Many of these include systematic reviews and meta-analyses, which synthesize many studies on a given topic.

Stress and mental health

Mindfulness-based programs have been shown to significantly reduce stress in a variety of populations, ranging from caregivers of people living with dementia to children during the COVID-19 pandemic.

Meta-analyses published during the pandemic show that mindfulness programs are effective for reducing symptoms of post-traumatic stress disorder, obsessive-compulsive disorder, attention-deficit/hyperactivity disorder and depression – including the particularly vulnerable time during pregnancy and the postnatal period.

Mindfulness-based programs also show promise as a treatment option for anxiety disorders, which are the most common mental disorders, affecting an estimated 301 million people globally. While effective treatments for anxiety exist, many patients do not have access to them because they lack insurance coverage or transportation to providers, for instance, or they may experience only limited relief.

It’s important to note, however, that for those affected by mental or substance use disorders, mindfulness-based approaches should not replace first-line treatments like medicine and psychotherapy such as cognitive behavioral therapy. Mindfulness strategies should be seen as a supplement to these evidence-based treatments and a complement to healthy lifestyle interventions like physical activity and healthy eating.

How does meditation work? A look into the brain

Studies show that regular meditators experience better attention control and improved control of heart rate, breathing and autonomic nervous system functioning, which regulates involuntary responses in the body, such as blood pressure. Research also shows that people who meditate have lower levels of cortisol – a hormone involved in the stress response – than those who don’t.

A recent systematic review of neuroimaging studies showed that focused attention meditation is associated with functional changes in several brain regions involved in cognitive control and emotion-related processing. The review also found that more experienced meditators had stronger activation of the brain regions involved in those cognitive and emotional processes, suggesting that the brain benefits improve with more practice.

A regular meditation practice may also stave off age-related thinning of the cerebral cortex, which may help to protect against age-related disease and cognitive impairment.

Limitations of meditation research

This research does have limits. These include a lack of a consistent definition for the types of programs used, and a lack of rigorously controlled studies. In gold-standard randomized controlled trials with medications, study participants don’t know whether they are getting the active drug or a placebo.

In contrast, in trials of mindfulness-based interventions, participants know what condition they are assigned to and are not “blinded,” so they may expect that some of the health benefits may happen to them. This creates a sense of expectancy, which can be a confounding variable in studies. Many meditation studies also don’t frequently include a control group, which is needed to assess how it compares with other treatments.

Benefits and wider applications

Compared with medications, mindfulness-based programs may be more easily accessible and have fewer negative side effects. However, medication and psychotherapy – particularly cognitive behavioral therapy – work well for many, and a combination approach may be best. Mindfulness-based interventions are also cost-effective and have better health outcomes than usual care, particularly among high-risk patient populations – so there are economic benefits as well.

Researchers are studying ways to deliver mindfulness tools on a computer or smartphone app, or with virtual reality, which may be more effective than conventional in-person meditation training.

Importantly, mindfulness is not just for those with physical or mental health diagnoses. Anyone can use these strategies to reduce the risk of disease and to take advantage of the health benefits in everyday life, such as improved sleep and cognitive performance, elevated mood and lowered stress and anxiety.

Where to get started?

Many recreation centers, fitness studios and even universities offer in-person meditation classes. For those looking to see if meditation can help with the treatment of a physical or mental condition, there are over 600 clinical trialscurrently recruiting participants for various conditions, such as pain, cancer and depression.

If you want to try meditation from the comfort of your home, there are many free online videos on how to practice, including meditations for sleep, stress reduction, mindful eating and more. Several apps, such as Headspace, appear promising, with randomized controlled trials showing benefits for users.

The hardest part is, of course, getting started. However, if you set an alarm to practice every day, it will become a habit and may even translate into everyday life – which is the ultimate goal. For some, this may take some time and practice, and for others, this may start to happen pretty quickly. Even a single five-minute session can have positive health effects.

This is a comprehensive article on a most important topic.

For whatever is happening in our world it is getting busier especially for those that are a great deal younger than me.

New Years’ Resolutions

Finding one that really works.

Whatever age we are and in many different cultures the New Year holds out so much hope. It seems an opportunity to start anew, to put the habits of last year behind us, to embrace a new start. Yet all the evidence is that a New Year’s Resolution will not make it through to February.

That is why I picked up on a recent article in The Conversation, that they kindly allow to be republished.

Why you should give the gift of mindfulness this New Year

By Jeremy David Engels

The start of another year can feel magical to many of us. Even though the days remain short and dark, the flip of the calendar can make it seem new beginnings with new resolutions are possible.

Mindfulness scholars and teachers like me call resolutions “habit breakers,” as they can overcome patterns that no longer serve individuals. However, research suggests that many resolutions fail by the end of January.

But a key to ensuring that resolutions stick is to choose one that will make a meaningful difference in your life. Seeing a real, tangible benefit can provide inspiration to keep going when all of life is telling us to let things go back to how they were before.

Living more mindfully is a common New Year’s resolution. This year, try gifting it to others.

The meaning of mindfulness

Mindfulness has been shown to have a number of meaningful health benefits – it can help reduce anxiety and promote healing in those suffering from long-term chronic illness.

The practice is based on an insight first described by ancient Buddhist texts that human beings have the capacity to observe experience without being caught up in it. This means, simply and wonderfully, that it is possible to observe ourselves having a craving, or a happy thought, or even a scary emotion, without reacting in the moment in a way that amplifies the feeling or sends the mind spiraling off into thinking about old memories or anticipating events.

This practice can help calm the mind and the body as we learn not to react to experience with likes and dislikes or judgments of good and bad. It does not make us cold or apathetic but more fully present.

Mindfulness in a distracted world

One of the challenges of practicing mindfulness in our contemporary world is that there has been a profound transformation in human attention. The artist Jenny Odell argues that in our “attention economy” human attention has been transformed into a commodity that big corporations buy and sell. This economy rests on a technological revolution of mobile phones and social media that makes it possible for corporations to reach us with content that can capture and monetize our focus, at every moment, every day, and no matter where we may be.

The constant need to be checking our phones keeps us from being fully present. Abdulhamid Hosbas/Anadolu Agency via Getty Images

The needy little devices most people carry in their pockets and wear on their wrists, incessantly beeping and buzzing and chirping, are a perpetual diversion from the present moment. The result is that it can feel as though our ability to focus, and be fully present, has been stolen.

But mindfulness can help us resist the attention economy and savor the things that make life special, like being together with those we love.

The gift of mindfulness

While most mindfulness research focuses on the individual benefits of the practice, scholars like me argue that we not only practice mindfulness for ourselves but that we can also practice it for others. It can help us build stronger, healthier relationships.

The sad truth is that living in the attention economy, most of us have become bad listeners. However, just as it is possible to watch ourselves having an experience without reacting, it’s possible to watch another person have an experience without getting tied up in reactivity and judgment. It’s possible simply to be present.

The gift of mindfulness is a practice of listening with compassion to another person describe their experiences. To give this gift means putting away your phone, turning off social media, and setting aside other common distractions. It means practicing being fully present in another person’s presence and listening to them with complete attention, without reacting with judgment, while resisting the urge to make the interaction about you.

If we judge the value of gifts based on how much they cost, this gift may seem worthless. But in a distracted world, I argue, it is a precious one.

It is not a gift that you will wrap, or put inside a card; it’s not one you will have to name as a gift or draw attention to. It’s something you can do right now.

ooOOoo

Professor David Engels is spot on. The number of people who are wedded to their cell phone, especially the younger ones of us, is frightening. Many years ago I was fortunate to have a counsellor who was into mindfulness and some of the good practices have stayed with me.

So, please, if you are thinking that your use of a cell phone is intrusive, even slightly, then let this New Year present a new you!

P.S.

And while we are on the subject of New Year’s Resolutions try this one. It is not a long video but it is extremely important; it concerns our diet and our health!

The tradition of Christmas

It goes back much further than the Christian church.

Jean and I are atheists and have been all our lives. Therefore we tend to take more notice of the Winter solstice (that is today as the day that I am preparing this post) rather than Christmas Day and our sense that it is a product of Jesus Christ being born on the 25th; or so I thought!

But the tradition of a Christmas tree in particular goes much further back, as this article from The Conversation sets out.

ooOOoo

The Christmas tree is a tradition older than Christmas

Why, every Christmas, do so many people endure the mess of dried pine needles, the risk of a fire hazard and impossibly tangled strings of lights?

Strapping a fir tree to the hood of my car and worrying about the strength of the twine, I sometimes wonder if I should just buy an artificial tree and do away with all the hassle. Then my inner historian scolds me – I have to remind myself that I’m taking part in one of the world’s oldest religious traditions. To give up the tree would be to give up a ritual that predates Christmas itself.

A symbol of life in a time of darkness

Almost all agrarian societies independently venerated the Sun in their pantheon of gods at one time or another – there was the Sol of the Norse, the Aztec Huitzilopochtli, the Greek Helios.

The solstices, when the Sun is at its highest and lowest points in the sky, were major events. The winter solstice, when the sky is its darkest, has been a notable day of celebration in agrarian societies throughout human history. The Persian Shab-e Yalda, Dongzhi in China and the North American Hopi Soyal all independently mark the occasion.

The favored décor for ancient winter solstices? Evergreen plants.

Whether as palm branches gathered in Egypt in the celebration of Ra or wreaths for the Roman feast of Saturnalia, evergreens have long served as symbols of the perseverance of life during the bleakness of winter, and the promise of the Sun’s return.

Christmas slowly emerges

Christmas came much later. The date was not fixed on liturgical calendars until centuries after Jesus’ birth, and the English word Christmas – an abbreviation of “Christ’s Mass” – would not appear until over 1,000 years after the original event.

While Dec. 25 was ostensibly a Christian holiday, many Europeans simply carried over traditions from winter solstice celebrations, which were notoriously raucous affairs. For example, the 12 days of Christmas commemorated in the popular carol actually originated in ancient Germanic Yule celebrations.

The continued use of evergreens, most notably the Christmas tree, is the most visible remnant of those ancient solstice celebrations. Although Ernst Anschütz’s well-known 1824 carol dedicated to the tree is translated into English as “O Christmas Tree,” the title of the original German tune is simply “Tannenbaum,” meaning fir tree. There is no reference to Christmas in the carol, which Anschütz based on a much older Silesian folk love song. In keeping with old solstice celebrations, the song praises the tree’s faithful hardiness during the dark and cold winter.

Bacchanal backlash

Sixteenth-century German Protestants, eager to remove the iconography and relics of the Roman Catholic Church, gave the Christmas tree a huge boost when they used it to replace Nativity scenes. The religious reformer Martin Luther supposedly adopted the practice and added candles.

But a century later, the English Puritans frowned upon the disorderly holiday for lacking biblical legitimacy. They banned it in the 1650s, with soldiers patrolling London’s streets looking for anyone daring to celebrate the day. Puritan colonists in Massachusetts did the same, fining “whosoever shall be found observing Christmas or the like, either by forbearing of labor, feasting, or any other way.”

German immigration to the American colonies ensured that the practice of trees would take root in the New World. Benjamin Franklin estimated that at least one-third of Pennsylvania’s white population was German before the American Revolution.

Yet, the German tradition of the Christmas tree blossomed in the United States largely due to Britain’s German royal lineage.

Taking a cue from the queen

Since 1701, English kings had been forbidden from becoming or marrying Catholics. Germany, which was made up of a patchwork of kingdoms, had eligible Protestant princes and princesses to spare. Many British royals privately maintained the familiar custom of a Christmas tree, but Queen Victoria – who had a German mother as well as a German grandmother on her father’s side – made the practice public and fashionable.

Victoria’s style of rule both reflected and shaped the outwardly stern, family-centered morality that dominated middle-class life during the era. In the 1840s, Christmas became the target of reformers like novelist Charles Dickens, who sought to transform the raucous celebrations of the largely sidelined holiday into a family day in which the people of the rapidly industrialized nation could relax, rejoice and give thanks.

His 1843 novella, “A Christmas Carol,” in which the miserly Ebenezer Scrooge found redemption by embracing Dickens’ prescriptions for the holiday, was a hit with the public. While the evergreen décor is evident in the hand-colored illustrations Dickens specially commissioned for the book, there are no Christmas trees in those pictures.

Victoria added the fir tree to family celebrations five years later. Although Christmas trees had been part of private royal celebrations for decades, an 1848 issue of the London Illustrated News depicted Victoria with her German husband and children decorating one as a family at Windsor Castle.

The cultural impact was almost instantaneous. Christmas trees started appearing in homes throughout England, its colonies and the rest of the English-speaking world. Dickens followed with his short story “A Christmas Tree” two years later.

Adopting the tradition in America

During this period, America’s middle classes generally embraced all things Victorian, from architecture to moral reform societies.

Sarah Hale, the author most famous for her children’s poem “Mary had a Little Lamb,” used her position as editor of the best-selling magazine Godey’s Ladies Book to advance a reformist agenda that included the abolition of slavery and the creation of holidays that promoted pious family values. The adoption of Thanksgiving as a national holiday in 1863 was perhaps her most lasting achievement.

It is closely followed by the Christmas tree.

While trees sporadically adorned the homes of German immigrants in the U.S., it became a mainstream middle-class practice when, in 1850, Godey’s published an engraving of Victoria and her Christmas tree. A supporter of Dickens and the movement to reinvent Christmas, Hale helped to popularize the family Christmas tree across the pond.

Only in 1870 did the United States recognize Christmas as a federal holiday.

The practice of erecting public Christmas trees emerged in the U.S. in the 20th century. In 1923, the first one appeared on the White House’s South Lawn. During the Great Depression, famous sites such as New York’s Rockefeller Center began erecting increasingly larger trees.

Christmas trees go global

As both American and British cultures extended their influence around the world, Christmas trees started to appear in communal spaces even in countries that are not predominately Christian. Shopping districts in Dubai, United Arab Emirates, Hong Kong and Tokyo now regularly erect trees.

The modern Christmas tree is a universal symbol that carries meanings both religious and secular. Adorned with lights, they promote hope and offer brightness in literally the darkest time of year for half of the world.

In that sense, the modern Christmas tree has come full circle.
