The name of this blog, Rainbow Juice, is intentional.
The rainbow signifies unity from diversity. It is holistic. The arch suggests the idea of looking at the over-arching concepts: the big picture. To create a rainbow requires air, fire (the sun) and water (raindrops) and us to see it from the earth.
Juice suggests an extract; hence rainbow juice is extracting the elements from the rainbow, translating them and making them accessible to us. Juice also refreshes us and here it symbolises our nutritional quest for understanding, compassion and enlightenment.

Time Is Running Out, We’d Better Slow Down

There are lots of articles, books, presentations, podcasts, and videos that point to a rapidly shortening of time before a cataclysmic future overwhelms us. We hear that by 2050, and perhaps by 2030, we need to have reduced our dependence upon fossil fuels significantly. We read that, if we don’t do something urgently, then one-third of species on the Earth will be extinct by 2100. We look at the increasing polarisation around the world and fear for the possibility of another world war, and note with terror the likelihood that such a war could include nuclear weapons.

Or, perhaps we think of ourselves. Each birthday reminds us that we are one year older, one year closer to the end of our time on Earth. Yet, there are many things we still want to do, much we wish to accomplish and achieve.

Time is running out.

We must act with urgency.

We gotta do something, and fast.

We must complete our bucket list.

We have to save the planet.

We have to reduce carbon emissions. We have to transition to green technology soon.

Each of these sentiments are understandable. Yet, more than likely, they are unhealthy and unwise. Speeding up might get us there faster, but when we get there we will find that it is not where we wanted to be or what we expected.

Just look at the current situation we are in with carbon emissions. It can be argued that we have got to this position because we wanted to hurry up. We built, purchased, and drove private motorcars because we wanted to get from one place to another quicker. We tapped into the stored sunlight of fossil fuels so that we could more rapidly heat our homes and cook our meals. Those same fossil fuel power stations enabled the elites of the world to more quickly build their fortunes.

The mobile phone, too, is a go faster piece of technology. We can more quickly contact anyone, anywhere on the planet. We can send text, photographs, and documents at the speed of light. That’s fast! Yet, those same phones have presented us with numerous problems; e-waste, cyber-bullying, cognitive decline, and the modern disease of nomophobia – the fear of not having access to a mobile phone.

The Vietnamese Buddhist monk, Thich Nhat Hanh names all this as Habit Energy which he describes as,

"We are always running and rushing. It has become a habit, the norm of everyday living. We run all the time, during our sleep, the time we are supposed to be resting and regenerating our bodies. We can be worst enemies, in conflict with ourselves, and therefore, you can easily start conflict with others..."

It is exhausting us. It is exhausting the planet as well.

‘But surely we have to do something quickly in the face of imminent and mounting crises. We are in the midst of a predicament of massive proportions. We can’t sit back. We have to get on with it. We have to save the planet, and ourselves.’

I hear such sentiments every week.

And, we are responding to this predicament in exactly the way described. We are quickly digging up not only fossil fuels, but also minerals to power the green energy transition. The speed with which we are doing this has not reduced electricity consumption at all – it has simply added to it. We are using twice as much electricity today as we were at the turn of the century. Wind and solar electricity production is 1/3rd of that increase. Wind and solar have added to the consumption, they have not displaced it. They are not proving to be alternatives at all.

What if we slowed down?

What if, as a friendly psychologist told me about four decades ago, we stopped awhile and smelt the roses?

At an individual level slowing down has been shown, in numerous studies, to lower our levels of anxiety and stress, improve our cognitive responses, enhance our connection and relationships with other people, and elevate our body’s ability to heal and recuperate. In short, slowing down is good for our well-being.

For the planet too, our slowing down would have tremendous benefit. We have vastly overshot the carrying capacity of Earth. Overshoot occurs when the Earth can no longer recover from the effects of human waste and pollution quicker than the waste and pollution is created. Overshoot is also when the Earth can no longer replenish the stores of forest, minerals, water, and other components of an eco-system faster than humans are extracting and exploiting those components.

We have been in this state of overshoot for many decades, and the rate of overshoot is increasing. Globally, we now require 1.6 Earths to satisfy our rate of extraction and levels of pollution. This figure (1.6 planets) is unevenly distributed around the world. If everyone lived as those in rich nations lived, we would need between three and six Earths to satisfy our consumption levels.

Slowing down would assist the Earth in restoring its balance immensely.

The Earth is always seeking to restore balance and homeostasis. But it needs time to do that. We could greatly assist that process by simply slowing down.

8,699,999 + 1

Ernst Haeckel's
"Tree of Life."
(note the position of MAN)
It is estimated that there are 8,699,999 animal species on Earth. Plus one; the species we call Homo sapiens.

That makes a total of 8.7 million species. Of these 8.7 million, it is thought that as many as 86% have not yet been discovered, let alone described. Yet, that number is only the animal species, a small fraction of all species.

If plant and microbial species are added into the count then the total number of species upon the Earth could be one trillion, or more.

Yet, that one species – Homo sapiens – has come to domesticate, dominate, or destroy many of the other species that share this planet with us.

Of all the mammals upon the Earth, we humans account for 34% of the total biomass. Mammals domesticated by us make up 62% of the total biomass. That means that just 4% of the Earth’s total mammalian biomass is made up of wild mammals.1

Just 4%! The biomass of wild land mammals has declined by an estimated 85% since humans emerged onto the planet. 85%! The numbers are staggering.

Humanity has also domesticated chickens, which are not mammals. What about them? Well, that is a sordid tale as well. Domesticated chickens make up 71% of the total bird mass on the planet.

What of the number of species we have destroyed?

It is estimated that the average length of time for a species to exist on the Earth, before becoming extinct, is between one and ten million years, with most going extinct at the lower end of this range. The extinction rate, since the arrival of humans, is assessed as being between 100 and 1,000 times the natural background extinction rate. Another staggering number.

All the numbers and figures cited above are because of that one extra species added to the 8,699,999 total for all animal species. Just one! Yet another staggering number.

How did, and why should, one species, amongst 8.7 million animal species, come to domesticate, dominate, and destroy so many creatures?

Within western cultures the origin can perhaps be traced back to its genesis. Yes – Genesis. The first book of the Bible. Whether a person today, living a westernized lifestyle, is a religious follower of the Bible is immaterial. Western culture has its roots firmly embedded within Judeo-Christian belief systems.

Genesis 1, verses 26-28 twice repeats the phrase that humans are to ‘have dominion over the fish of the sea, over the birds of the air…and over every living thing that moves on the earth.’2 This word dominion has for some two and a half thousand years often been interpreted as meaning mankind has the right to subdue, control, and exploit the creatures of the earth.

Over the past couple of centuries this interpretation has come under scrutiny, with many Biblical scholars and linguists advising that the original Hebrew words limited the interpretation to meaning a stewardship or governance.

Notwithstanding the debates within Biblical scholarship, the right of dominance is the one that has firmly entrenched itself within western worldviews. By extension, this right of dominance and control led those worldviews to a belief in human exceptionalism – the belief that humans are different from, and superior to, other forms of life.

This Biblically mandated role for humankind remained a foundation of the human journey for many centuries. It was not until the middle of the 19th century that the Biblical position on the place of humans was challenged. Darwin’s On The Origin Of Species, published in 1859, introduced humans to the Theory of Evolution. But even this theory did not dislodge the belief in human exceptionalism. If anything, it gave it pseudo-scientific credibility.

The German naturalist, Ernst Haeckel, was fascinated by Darwin’s ideas and actively promoted them. In doing so, Haeckel depicted evolution as a tree with man (sic) placed at the apex of the tree, insinuating that humanity was the inevitable and only possible outcome for evolution (see graphic). This depiction still has favour today. Human exceptionalism remains embedded within our westernized worldview.

With two such powerful influences upon westernised worldviews – the Biblical one and the evolutionary tree one – it is little wonder that the 8.7 million species upon the Earth have become domesticated, dominated, and destroyed by just one species – us.

A final comment should be made about this one species. Yes, we are one species amongst 8.7 million, but we don’t all share the same worldviews. The worldviews summarised above have been developed over millennia within western cultures. They are not shared by many indigenous and nature-based cultures. However, the process of colonisation, beginning in the late 15th century, has all but eradicated any other worldview.

Human exceptionalism remains a dominant view throughout the world.

8,699,999 creatures continue to suffer because of this view.

Voyage Without Contact

On 5th September 1977 Voyager 1 was launched from Cape Canaveral in Florida. Today (13th November 2025) Voyager 1 will reach one light-day from Earth. One light-day is close to 26 billion kilometres. That’s a long way.

Yet, in astronomical terms it is not far at all. Although Voyager 1 has gone past the orbits of the outer planets of our solar system, it remains within the gravitational realm of the Solar System. A region of Space, known as the Oort Cloud, is considered to mark the edge of the Solar System’s gravitational influence. This vast “cloud” is where many of the comets that we see are thought to originate. Voyager 1 is not expected to reach this “cloud” for another few centuries and then remain within the cloud for perhaps thousands of years.

When Voyager 1 was launched we had not yet confirmed the existence of any planets outside the Solar System. It was not until 15 years later (in 1992) that the first exoplanet (planet outside the Solar System) was confirmed – and that planet was 2,300 light-years from Earth. Now, over 6,000 exoplanets have been confirmed to exist, with less than 4% of these likely to be Earth-like. However, current estimates put the number of Earth-like exoplanets in our galaxy somewhere in the range from 300 million to 40 billion.

But, contacting any life living on such exoplanets is highly unlikely.

The nearest known Earth-like exoplanet is Proxima b, circling the star Proxima Centauri, part of a triple star system in the constellation Centaurus. Proxima Centauri is 4.25 light-years from us, making it the nearest star to our own star – the Sun.

That doesn’t sound too far, does it – only a bit over 4 light years away.

However, do the mathematics. If Voyager 1 headed directly to Proxima Centauri, then it would arrive there in approximately 74,500 years – 74,452 years more than it has already travelled.

So, don’t keep watching your phone for updates on its arrival.

Now, consider this. Suppose Proxima b does have intelligent life living there. Suppose further, that those Proximians also launched a space probe, with the same technology we had, on the same day we did – 48 years ago. Then, it will be another 37,250 years before the two probes pass by each other in Deep Space.

Here’s yet another thought experiment. Suppose that a space probe emanating from Proxima b were to arrive on our planet Earth tomorrow. Then, that probe would have been launched 74,500 years ago. Can you recollect the state of the world all those years ago?

74,500 years ago we were sharing the planet with another member of the genus Homo – Homo neanderthalensis. Homo sapiens (as we came to be called) had left Africa, was about to arrive in Australia, and it was to be several thousand years before the Americas or the islands of the Pacific were settled. We had invented stone tools and were leaving our marks in forms of artwork on cave walls.

All those years ago we certainly had not invented the technology required to build a machine like Voyager 1 and be able to send it off into space.

This leaves us with two big questions.

Question 1: Are we ever likely to reach the stars?

Question 2: Are inhabitants from other star systems ever likely to reach us?

The answer to both questions has to be: Not likely, or at least with a very low probability.

That answer leads to two more important questions.

When are we going to realise that this is the planet we have, the only one we will ever have available to us?

When are we going to treat this Earth as our (only) home?

Known For All The Wrong Reasons

One of 500 Dafur refugee children's drawings
from the Waging Peace collection
Pol Pot, Stalin, Hitler, Idi Amin, Franco, Kai-Shek, Mao, Hussein – all well-known names. Most likely though, they are known for the wrong reasons. Asked to associate single words with any of these names and many people would come up with a list looking something like this: dictator, despot, genocide, holocaust, brutal etc.

We know their names because of the atrocities committed under their rule.

Stalin is estimated to have had 40-60 million killed during his regime.

Mao Tse Tung had somewhere between 45 million and 75 million killed whilst in power.

During Hitler’s Reich the number of deaths is estimated at 17-20 million.

Chiang Kai-Shek murdered about 10 million.

Approximately 2 million were killed during Hussein’s rule. Pol Pot’s Cambodian rule killed a similar number.

The number killed during Idi Amin’s reign is indeterminate but estimated at between 100,000 to 500,000. Franco, in Spain, is responsible for about 400,000 deaths.

Those eight names, all from the 20th century, were responsible for at least a conservative estimate of 116 million deaths. The death toll could have been as high as 170 million. And that number is only by those eight. Others that could be mentioned are: the dictator Milosevic, and the genocides of Rwanda, Dafur, Armenia, and the Rape of Nanking.

More than 116 – 170 million wrong reasons for knowing their names.

In 1948 the Genocide Convention was drafted and gained 153 state parties to it (as of February 2025.) The Convention defines genocide as the ‘… intent to destroy, in whole or in part, a national, ethnical, racial, or religious group…’  The Convention includes in the rubric of genocide not simply outright killing, but also the causing of bodily or mental harm, deliberately imposing conditions of life that will bring about destruction, preventing births within the group, and forcibly transferring children from the group to another group.

When genocide is considered in the light of this Convention, then the total numbers given above are likely to rise by a considerable number of orders of magnitude.

This definition also enables us to recognise a number of other historical events as genocide. The colonisation (including slaughter) of native Americans by European invaders from the 16th century onwards, the Atlantic slave trade, the stolen generation in Australia.

Genocide did not end with the signing of the Genocide Convention, and genocide did not end with the shift from the 20th to the 21st century. Genocide is continuing.

We can name the names of those contributing to genocide today.

They also will be known for all the wrong reasons when the history of the 21st century is written.

Happy Hour

In many countries of the world pubs, inns, and restaurants advertise a Happy Hour. Usually in the early evening, Happy Hour is marked by reduced prices for drinks in a marketing effort to get customers in at a time when the venue is quiet.

In Australia graduating High School students engage in what is known as Schoolies Week. This is a week following the end of final year exams. Sadly, this time can be marred by heavy drinking, drugs, and violence.

Both these cultural occasions may be poor substitutes for activities now lost from our westernised experience.

Thousands of years ago before we began to settle in large towns and villages, our community would have come together around a fire. We would have shared food, told stories, sung songs, and danced together. It would have been a time for rejoicing, laughing, and connecting. It would have been the time when stories of the hunt would have been told, or the location of a tree about to bear fruit was mentioned. Perhaps an Elder or the Shaman of the clan would have re-enacted the clan’s history.

Is this what Happy Hour tries to duplicate, but without understanding what it is being resurrected? Without true Elders and Shaman Happy Hour can only ever be a semblance of what has been.

So too, Schoolies Week is a pitiable surrogate for the coming-of-age rituals that once marked the transition from childhood to adulthood in our cultural past?

Yet there is a memory in these modern-day events. Although we may have lost and forgotten the ceremonies, rituals, and rites that marked our time many millennia ago, we instinctively know that something is missing.

How many other modern-day customs are an attempt to re-engage with something primally human? Yet, many of these modern customs have been stripped of their sacredness and their significance. Here are just a few that come to mind:

Childbirth. Once a ceremony and rite involving the women of the community it is now often confined to a sterile hospital setting and overseen by men.

Education. Once an ongoing aspect of life where one learnt throughout the day, and as things arose, in an outdoor setting. Nowadays, education is shut off inside classrooms and lasts only a limited number of years.

Elderhood. Once a respected role in a community, a true Elder held the sacred knowledge and wisdom of the clan. Today, very few true Elders remain, and we have substituted it with “Olders” who are then siphoned off to Old Folks Homes, away from the community.

If our bodies retain a memory of ancient rituals, ceremonies, and rites, then can we reach into the depths of our collective soul to regain the meaning and sacredness of them?

Just a thought to ponder.

Five Best Inventions

Coffee and art
combined
Last week’s blogpost was entitled Five Worst Inventions. So, this week I am offering my thoughts on the Five Best Inventions, lest I be accused of negativity. I did not go through as rigorous a process as last week; I came up with the five without previously determining the criteria by which I would decide. The only similarity with process was that I was walking on the beach again when I came up with these five.

What I found interesting when I arrived at my top five was that three of them related to our creative and artistic endeavours. That’s appropriate, I thought, because it is our creativity, and artistry that contributes hugely towards our sense of well-being and our pleasure in life. That last sentence may sound intuitively, and logically, correct, yet the connection has been studied by researchers. As an example, this study from Malaysia ‘demonstrates that creativity is beneficial to subjective well-being.’1

Here are my contenders for Five Best Inventions, in no particular order.

Painting. One of the favourite activities of young children at home, in pre-school, or primary school is drawing. There seems to be something innate about the activity that young children are drawn to.

The earliest known example of a drawing/painting by a human is that of a red hand stencil in Maltravieso Cave in Spain and was made by a Neanderthal more than 64,000 years ago. The earliest known figurative paintings are in caves in Indonesia and Borneo and are dated at more than 40,000 years old.

All cultures appear to have invented painting in one form or another – whether on rock, on wood, or on our own bodies. Painting allows us to be creative and expressive, as well as being a medium for the communication of a thought, idea, or story.

Painting was possibly a precursor to carving which was initially etching like depictions upon rock – petroglyphs being the technical term. The oldest of these are found at Murujuga, Western Australia and are dated at 40,000 to 50,000 years old. The site was declared a World Heritage Site in July 2025.

Painting and carving have undergone many changes and evolved differently in different cultures. It has given us the elaborate masks of New Guinea, the beauty of the Sistine Chapel, and the intricacy of Māori wood and greenstone carvings.

Painting is a marvellous invention, and we don’t have to be children to continue to enjoy viewing it or creating it.

Writing. Writing may well have evolved from painting. Writing enables us to tell stories and keep accounts. In the last few millennia it has provided the means to some of the world’s great literature. In western cultures, would we have a Shakespeare, an Emily Brontë, or a Tolstoy if not for the invention of writing?

Sumerian is thought to be the oldest written language, dating from about 3400 BCE. Early writing from this culture was of a book-keeping style, and then the writing down of poems or sagely advice from one generation to the next. The world’s first written fictional story appears to be the Epic of Gilgamesh written probably about 2100 BCE and, in poetic form, tells the tales of a Sumerian king.

Today our reading options are immense; somewhere between one million and four million novels are published each year. All thanks to the invention of writing.

Drums. When we think of arts, then not only does painting, sculpture, and literature come to mind, but so too does music. The first musical instruments to be invented were undoubtedly percussion instruments. The first membranophone (a drum constructed using a stretched membrane) can be traced to China in the period from 5500 – 2350 BCE and using alligator skins. Because skins tend to degrade, earlier drums may well have been invented without leaving a trace in the archaeological record.

Drums and drumming greatly enhance one of our other (human) artistic forms – dance. Today, the variety of types of drums is immense. There are the drums of the symphony orchestra, conga drums, the many drums of Africa, and in our modern age the drum kit of rock bands.

Drums continue to beat out the rhythms of dancing, marching, and are used in various shamanic and in other ritualistic settings.

Bicycles. As a means to assist us getting around, the bicycle surely cannot be beaten. Its environmental impact is insignificant, and it enables us to keep fit.

In 1817 the Dandy horse was invented – a two-wheeled machine that could be sat upon, steered, and propelled by pushing along with the feet. The first bicycle to incorporate a mechanical crank drive and pedals came into being in the 1860s.

Today, there are more than one billion bicycles in the world. It is a popular form of transport and gave rise to the sport of cycling. The Tour de France cycling race (lasting three weeks) is considered to be the world’s biggest annual sporting event, and certainly the most watched cycling event.

Coffee. After water, coffee vies with tea for the second-most consumed beverage in the world. The number of cafés in the world reaches into the tens (or even hundreds) of thousands. Shanghai is believed to be the city with the highest number of cafés, with over 8,530 in 2024. Australia is home to 27,000 coffee cafés.

The exact date of the invention of the coffee drink is indeterminate. Legend tells of an Ethiopian goat-herder in the 6th century, named Kaldi, noticing that his goats took a liking to the bean. By 1000 CE Arab traders were bringing the bean back and cultivating it. By boiling the beans they created a drink they called qahwa which meant that which prevents sleep. Qahwa appears to be where we get the word coffee from.

Today more than 2.25 billion cups of coffee are consumed every day globally. For many, coffee is one of the world’s most pleasurable inventions.

So, get on your bicycle, bike down to your local café for a coffee, perhaps write a letter or poem whilst there, draw or paint a picture of your surroundings, or listen to a busker playing the bongoes on the pavement outside the café. What could be better?

Five Worst Inventions

Berlin Wall
A few days ago I was taking my (almost) daily walk along the beach, allowing the water to wash around my feet, ankles, and calves. I listened to the waves lapping upon the shore and the sound of gulls flying overhead. The sounds and sights were pleasant and calming.

As I continued walking and paddling I noticed a man coming towards me holding a mobile phone in front of him, peering at it. When we passed I waved and offered a cheery “good morning.” There was no reaction, he continued on, not seeming to notice his surroundings or my greeting.

I thought to myself, mobile phones have to be one of the worst inventions we humans have ever made. For the rest of my walk I thought about that, and wondered what would be my “top five” worst inventions? What criteria would I use to make such a judgment?

By the end of my walk I had come up with these three criteria for deciding on the “top five” worst inventions of humankind: 1. That the invention had a negative impact upon the earth and our relationship with nature, 2. That the invention served to increase the separation between us and exacerbate our intolerance of one another, and 3. That the invention worsened our mental health and/or our sense of well-being.

With these criteria in mind, here are my “top five” worst inventions. Please note that these are subjective and you may not agree, and may have a different “top five.” Also, each of these inventions may have their benefits, but, as I see it, the harms are greater. What are my “top five”? In no particular order they are:

Fences. The purpose of a fence is to either keep someone or something in or keep someone or something out. Their main purpose is to divide. Archaeological evidence shows that the first fences, often made of earth mounds, stones, or wood, appeared about 10,000 to 5,000 BCE. They arose in conjunction with sedentary agriculture and functioned to keep predators and scavengers out of crops, or to keep domesticated animals in.

Eventually, because of the transition from hunter/gathering to sedentary living, fences became walls around villages, towns, and cities. They were erected to provide security from opposing groups of humans. They also became markers of a new human feature – the privatisation of land. Take a walk in the countryside these days and how many times do you see a sign on a fence that reads, Keep Out, Private Property?

Walls (simply more elaborate fences) are used commonly to separate and divide. In the last 100 years two of the most well known walls have been erected: the Warsaw ghetto wall erected in November 1940 used to imprison 460,000 Jews in an area of just 3.4 km2, and; the Berlin Wall, erected in August 1961, which divided the city of Berlin and separated families, friends, and lovers. Even today, walls exist in many cities of the world, and their purpose is to divide also. Most of us do not even think of them – they go under the rubric of gated communities.

Fences serve to separate us. They also serve to maintain our dominance over domesticated animals.

Ploughs. Ploughs are also linked to our domestication of plants and crops. Ploughs allow us to turn a diverse area of land into mono-agriculture, which is dependent upon the addition of pesticides, fungicides, and artificial fertilisers to ensure crop production.

The first ploughs seem to be hand-held plough-like devices used by early Egyptians to clear rocky soil. By the 6th millennium BCE oxen were being used to pull early ploughs in Mesopotamia and the Indus Valley.

As time progressed, ploughs became mechanised and automated. Ploughs have enabled huge multinational agriculture companies to wreak havoc upon the land with mono-cultural cropping.

Ploughs and plowshares are often referred to as the goal of pacifist and peace movements worldwide. The phrase, ‘They shall beat their swords into plowshares’ comes from the Bible (Isaiah 2.4). A statue bearing this sentiment is on display in the United Nations Art Collection.

Yet, as Stephen Jenkinson caustically points out, ‘From the land’s point of view, there is no difference between swords and plows.’ 1

Guns. The first guns were invented in China around 1000 AD, following the invention there of gunpowder in the ninth century. Guns spread throughout Eurasia during the 14th century, with the word gun coming to us from the Old Norse word gunnidr meaning war-sword. Hence, guns have been associated with warfare and violence since their inception.

It would be hard to propose a more lethal means of killing another human being (or animal for that matter) than a gun. Since the 14th century guns have morphed into; arquebuses, muskets, pistols, revolvers, machine guns, cannons, artillery, mortars, howitzers, tanks, and the modern-day drones that enable dissociated and anonymous killing.

The ultimate “gun” today is undoubtedly the nuclear warhead. There are well over 12,000 nuclear warheads in the world today, held by nine different countries. Russia and the USA hold the majority of these with more than 5,000 apiece.

Guns have worsened the divide between us.

Automobiles. I tossed up whether to identify this worst invention as the combustion engine or the automobile (utilising the combustion engine.) However, since there are now many vehicles that do not use the combustion engine as its automotive power, I opted for the automobile.

Whether the motive power is the combustion engine or an electric engine (or a combination of both) the automobile has had a terrible impact upon the environment of the Earth. Automobiles take up huge amounts of space in many of the cities of the world. The amount of land devoted to them (roads, streets, car parks) can be as much as 25% of the city’s area. The pollutants that automobiles emit are well known, but what may not be so well known is the weight of vehicles that contribute to the wear and tear of tyres. Some research suggests that tyre wear contributes 2,000 times more particulate pollution than the exhausts. EVs (electric vehicles) are not immune to this, indeed are worse, as the weight of an EV is significantly greater than that of a combustion engine vehicle.

In 2023 I coined the term autobesity to label the problems of automobiles. The blog is accessible here.

Mobile Phones. The mobile phone has only been available commercially since 1983 yet it has probably been responsible for an increase in social isolation, cyber bullying, teenage anxiety and depression, e-waste, environmental degradation, an increase in electricity usage, and a dumbing down of our cognitive abilities than any other such contraption.

When the inventor of the mobile phone, Martin Cooper, was testing out his invention he walked across a street whilst speaking on his phone. He later admitted to a friend that doing so was ‘probably the most dangerous thing I have ever done in my life.’ He is correct. A study in the US in 2009 found that 5,474 people had been killed because of the use of mobile phones in traffic. Repeated studies show that the use of mobile phones are responsible for 25% – 50% of all police-reported vehicle accidents.

I have covered this topic in greater depth in a blog available here.

The Worst Is Yet To Come

One invention that is currently underway could easily be the worst yet. Artificial Intelligence (A.I.) has the potential to exacerbate all other problems, making them worse than they already are (if that is conceivable.)

The godfather of A.I., Geoffrey Hinton, has been warning us for a few years now. In a recent interview Hinton cautioned that ‘If you want to know what life is like when you’re not the apex intelligence, ask a chicken.’ A short (2 min) excerpt from the interview is here, a longer (21 min) clip is here.

Even though he recognises benefits of AI, Hinton warns that ‘unless we do something soon, we’re near the end.’ A chilling thought. The lessons from the other five worst inventions would suggest there may not be much hope of us doing something soon.  

Next week I will post my "Five Best Inventions" list.
