Although this blog was begun to publicise my own fiction, there are so many interesting things to write about that the fiction element has been displaced by other kinds of stories; stories about geopolitics, concerns about global change (of which not least, climate change), and new developments in science and technology.
It currently seems to me, as an informed layperson, that the answer to the planet’s global warming crisis lies primarily not so much in technological advances as in social engineering for change. For example, livestock farming produces 18% of global greenhouse gas emissions. Halving the consumption of meat, to take only one measure, would have enormous health benefits for individuals and at a stroke, reduce greenhouse gas emissions. That’s the equivalent of removing the 2015 contributions of the two most populous countries, India and China! According to a 2006 FAO report, Livestock’s Long Shadow (416 pp.), cattle alone are responsible for more global warming than all forms of transportation put together.
Another quick fix would be to reduce national defence budgets and invest the money in women’s health and education, easier said than done, considering the political madness that one sees in countries around the world. This too can be changed if enough people around the world set their minds to it and realise that we, the people, are the drivers of political change. Politicians are servants. They are merely people responding to our collective angsts and biases.
As global temperatures rise, people try to cope by installing air-conditioning units. This compounds the problem, since electricity consumption multiplies and heat dissipates to the outside world, creating urban heat islands and causing yet more global warming. It’s like polluting an ocean. Imperceptible when only one person does it, but massive when done by millions. Here’s an exciting technological fix in the works that might help to solve the air-conditioning problem: thermoacoustic cooling.
The principle was apparently observed by glassblowers more than two centuries ago. They noticed a sound was created when blowing a hot glass bubble at the end of a cold, long tube. 19th century scientists figured the sound was produced by the thermal gradient, and resonance was giving extra energy to the air in the tube. Apparently the first modern application to capture this energy for cooling was used in NASA’s Space Shuttle Discovery in 1992. Today, there seem to be two companies, in the Netherlands and in France, who offer solutions based on this principle for pollution free cooling. Here’s a link to the websites of Dutch company, SoundEnergy and France-based Equium. The sooner such companies are commercially successful, the better for the planet. Here’s a simple demonstration of the principle showing the working of a thermoacoustic engine.
I’ve sporadically followed Paul Salopek’s six-year walk across the world in National Geographic. As someone who loves to walk in all kinds of terrain myself, I find his a fascinating journey, a wonderful way to see the world up close in all its varied colors, moods and seasons. This to me is real travel; travel measured in footsteps rather than miles in a car or hours of flight. The very word flight conjures images of an attempt to escape rather than a journey to explore and expand one’s horizons. For much of the journey, Paul’s companions have been pack animals and his long treks have brought him to a real and humble understanding of the rich variety of sentient life. For this reason, he speaks with simple sadness of the death of Raju, the donkey who accompanied him on his walk across much of northern India. See the National Geo article here.
I’ve aimed to walk 10,000 steps a day (around 5 miles/8 km) for the past few years and more or less achieved it, except when the weather’s been impossible. I was also surprisingly moved by the death of a feline friend last year. Maybe that’s why the article resonated with me. Maybe that’s why the following passage he quotes from Matthew Scully’s book Dominion lingers in the mind long after reading.
“How we treat our fellow creatures is only one more way in which each one of us, every day, writes our own epitaph—bearing into the world a message of light and life or just more darkness and death, adding to the world’s joy or to its despair… Perhaps that is part of the animals’ role among us, to awaken humility, to turn our minds back to the mystery of things, and open our hearts to that most impractical of hopes in which all creation speaks as one.” From Dominion: The Power of Man, the Suffering of Animals, and the Call to Mercy by Matthew Scully.
“…to awaken humility…” and to perhaps remind ourselves that a warming planet requires us to do this for our own salvation.
Several years ago, an Italian acquaintance said to me, “The growth of the Roman Empire was driven by testosterone, you know.” He was a polyglot polymath; a materials scientist by profession, and a keen historian who sometimes spouted Greek and Latin quotations to illustrate the points he made. Julius Caesar, as a promising young general in his thirties, felt like an under-achiever and a failure. He is known to have lamented that Alexander had conquered most of the known world by the age of thirty, while he himself was only a Quaestor (a local magistrate) in Rome. Caesar was forty years old when he formed the first Triumvirate with Crassus and Pompey. He then went on to defeat the Gallic tribes of modern day France over the next eight years, killing more than a million Gauls and Germans in the process (according to Plutarch) and enslaving a million more. Presumably, by the mores of his time, these deaths were considered necessary to establish rule of law, discipline unruly Roman citizens with firm leadership and ensure stable government.
After the Second World War, with American leadership and the newly instituted United Nations organizations in 1945, it was widely believed that conquest and rule by force of arms was a thing of the past. Post-1945 the world entered an era of global peace and the longest absence of major wars mankind has ever known. If today’s world outlook seems bleak, blame it on the internet and social media, which are able to convey local impacts of minor skirmishes into our homes with larger-than-life images. Brutal killings appear immediately on the screens we carry in our pockets, or on laptops and smart tablets in homes and offices. When the Cold War ended, American philosopher Francis Fukuyama famously declared the end of history. In a nutshell his thesis was: with the spread of globalization and its accompanying prosperity, liberalism would spread around the world. Fukuyama’s book “The End of History and the Last Man” was published in the heady post-Cold War days of 1992. Today Fukuyama confesses: Twenty five years ago I didn’t have a sense or a theory about how democracies can go backward. And I think they clearly can.” (Washington Post article here)
On the other hand, Harvard psychologist and popular science author Steven Pinker argues that humanity is currently experiencing decreasing levels of violence (TED talk, 20 minutes) However he argues that liberal values are under threat from authoritarian populism, religious fundamentalism and radicalism of the left and right. There is no doubt in my mind that liberal democracies will do better than dictatorships and autocracies in tackling the gravest problem facing humanity today, global climate change. And it is mainly in democracies that the #MeToo movement is taking shape. People involved in the movement are asking questions and demanding action from their governments. Have we reached a tipping point? Can this watershed moment go beyond words to drive meaningful action? My answer to these questions is an emphatic yes. The fact that the movement has unexpectedly taken root in Asia is an enormous portent of things to come.
African press reports indicate that in many countries on the continent, women are afraid to talk about sexual harassment, especially in many of its conflict zones. According to this Zimbabwe newsletter, four of the five riskiest cities for sexual assault and rape are in Africa. There also appears to be a direct correlation between sexual harassment and geopolitics. The greater the gender equality that exists in a country, the less likelihood of autocratic leaders. Strongmen (and wannabe strongmen) look on the exercise of power as a kind of pissing contest, with the Trumps and Erdogans of this world trying to outdo the Putins, Kim Jong-Uns and Dutertes. More women leaders coming to power in countries around the world as a result of the #MeToo movement would be the best news for global climate. Women are less likely to indulge in geopolitical pissing contests. On the one hand women are generally more inclined to collaborate and cooperate and and on the other, their plumbing discourages such childish displays, leaving them with more time to get on with the urgent tasks of governing.
A quotation from the Psalms recently came to mind. The days of our years are threescore years and ten; and if by reason of strength they be fourscore years, yet is their strength labour and sorrow; for it is soon cut off and we fly away. (Psalm 90, v. 10).
Having reached that Biblical milestone earlier this year, I recall a favourite uncle of mine quoting the above lines at me some decades ago when he reached the age of 70. At that time, his attitude was: I’ve done my bit for the world, and given you a good start. Now it’s up to your generation to carry on the good work. Study hard, find jobs, work hard, and you’ll end up like me, looking back on a life well-lived and enjoying the fruits of prosperity.
Based on the foundations laid by an earlier generation, many in this generation (myself included) worked hard and enjoyed a prosperous life, largely managing to evade the conflicts and other terrible things that happened around the world at different places and different times. We lived in a time of a rising tide lifts all boats otherwise known as trickle-down economics, but somehow gravity didn’t do what it was supposed to do, for the simple reason that human greed defies gravity. So instead of trickling down, money trickled up, slowly at first, until the present day when it’s become a roaring flood. Economic pundits (and most famously the pop group Abba) call it “The Winner Takes it All” syndrome. Economist Brian Arthur who has published a body of work on technology and society calls it “the network effect locking markets in to the domination of a single player.”
So here I am, at three score years and ten years thinking, the work’s not done yet; we’ve not laid the foundations of prosperity for coming generations, we’re not leaving behind a healthy planet for them. There’s still time, but there’s a lot of work to do, easily doable despite the shortening window of opportunity remaining, if enough people join in. Here are some links to steps for a healthier planet.
These are only small actions, but following the suggested prescriptions on only one of these links can greatly improve your own health as well as that of the planet. As a side benefit you might find, like Moses, that your eyes are not dimmed, nor your natural force abated. So here’s wishing you all the best for the future of the planet.
Remember the children’s tale of how the Grinch stole Christmas? Well, here’s a true life tale that tells a similar story. See the following link for the newspaper article that talks about the banned video.
See the video below.
Coming across some unsweetened chocolate containing dried figs and ham (prsut), the combination seemed so unusual that we picked a packet up to try at home later. This was in a little shop near the open air market of Ljubljana, the eminently walkable capital of Slovenia. The combination, when we tried it, was delicious and to be highly recommended. Tasting this reminded me of a bitterly cold winter evening some years earlier, wandering through a Christmas market in Vienna, when I was stopped by a bearded man who looked like a Peruvian pan flute player.
“You look cold,” he said.
“Yes, I am cold.”
“Try a mug of Aztec chili chocolate with rum,” he said. “It’ll warm you up in no time.”
So we bought two steaming mugs of his brew and soon felt a pleasantly mild fiery glow spread through our innards. It helped us forget frozen hands and the biting cold for a good half hour. Figs originally came from Asia Minor, modern day eastern Turkey, but they spread early all over the Middle East and the Mediterranean. Chocolate probably originated in Olmec lands around 1000 BC where they called it kakawa. The origin of the word chocolate is presumably from an Aztec word ‘xocoatl,’ a bitter drink they brewed from cocoa beans. Here’s a link to a brief history of chocolate.
A gourmet friend told me several years ago about a trip to Sicily where he ate the most delicious lasagna he’d ever tasted, in a nondescript restaurant in a small village. Curious, he asked the owner, who was also the cook, the secret to his lasagna. “Unsweetened chocolate,” the man explained, pointing to a thin brown layer in the middle.
The Olmecs gave us chocolate and avocados. Kiwi fruit were brought out of China and found a new home in New Zealand where its name changed from Chinese gooseberry to kiwi. Okra originated in Ethiopia and now is used by households from India to Florida. Sugarcane spread from India and New Guinea to the rest of the world. Potatoes and tomatoes also originated from South America, while chick peas came from Turkey and the Middle East as long as 8000 years ago. Ethiopia also gave the world coffee, probably via Mocha in modern day Yemen. Tea, as is well known, came from China.
Where is all this leading to? To people, of course. To the people who consume these foods and beverages all over the world. Thank goodness for the free movement of food and food habits. A world without hummus, okra, tomatoes, potatoes or, God forbid, coffee and tea would be a world of culinary despair. So the way the world is going right now, most nations are saying, ok, we’ll take your food but not your people. Imagine the long-term global poverty and despair that then ensues, not only immediately, but in the long run. Imagine a world of monocultures with no biodiversity! So next time you go to vote, remember to vote for culinary diversity, and the people that come with it. This idea is underlined in the following illustration and article from UK think tank Global Future about future diversity in business leadership.
I recently read of efforts by a young Swiss duo, both engineers, whose company, Climeworks, sucks CO2 out of the air and carbonates water, injecting the water underground into basaltic rock. To its own surprise, Climeworks finds that the gas converts to solid carbonate forms underground in a couple of years. So is this a stable way to remove greenhouse gases from the air? There are other uses for captured CO2 of course but the quantities are minuscule compared to global emissions. So the pundits talk of capturing the carbon dioxide and storing it in underground caverns or pumping it under pressure into the depths of the ocean. Why isn’t there more talk among technologists of reducing emissions, instead of accepting emissions as a given and figuring out ways of converting them at great cost to benign forms?
A friend recently commented on efforts to remove atmospheric CO2 and store it underground. It’s like swallowing gas, he says. You know what happens when you have too much gas. You either fart or burp, or both. Accumulated internal gas is painful and you wouldn’t do it to yourself, so why do they want to do it to the earth? Do they know what will happen when the earth farts? So why don’t we plant trees instead?
Planting trees is a solution. An average tree sucks up 25 kilos of carbon per year. Humans emit 30 to 40 gigatons of CO2 every year. Let’s say emissions are kept at 30 gigatons a year. Thirty billion tons. That’s… let’s see, forty trees take up one ton per year, so multiply 30 billion by 40… so you get 1,200 billion. That’s 1.2 trillion trees per year just to break even!
How many trees are there on earth already? I found a BBC report of a 2015 Yale University study that estimates the number of trees currently on earth at 3 trillion. That’s 3,000,000,000,000. Since atmospheric CO2 concentrations are going up steadily, the situation would be much worse without these 3 trillion trees. So we still have to suck up the additional 30 gigatons a year, or else reduce emissions. If we take 7 billion to be the global population, leaving aside the old, the infirm and the very young, that leaves around 3 billion people of tree planting age worldwide. In order for 3 billion people to plant 1.2 trillion trees per year, each one will have to plant 400 hundred trees per year.
Can (and would?) 3 billion people plant 1.2 trillion trees in a year? Of course not. But if even 10% of that number were to plant 10% of the target, we would be well on our way to doing what we need to do. Is this realistic? Quick answer: No. So is there a quick fix? Yes. Eat less meat. Depending on the type of feed, a cow produces 70 to 120 kg. of methane per year. Remember, methane as a greenhouse gas is 23 times more potent than CO2, so cutting down on meat is a quick way to reduce emissions. And it has the added benefit of freeing up pastureland for tree planting. So now we’re beginning to get a handle on things.
If we pump huge quantities of CO2 underground and undersea, the earth might fart (so to speak), with unintended consequences. But cows already fart on an ongoing daily basis, emitting considerable quantities of methane, so eating less meat is a relatively painless quick fix. And then there are lots of concomitant steps that are in the process of hesitantly being implemented, like switching to public transportation and electric cars. And, oh yes, the most environmental step the world is taking is the #MeToo movement! Let’s write that on our foreheads as a reminder to the world. Education and empowerment of women is the fastest way to reduce global greenhouse gas emissions and save our planet.
