“Well, should we just give up then?”

If only I had a dollar for every time I have heard this, always from well-meaning people. It is all too common if you talk about climate change, constraints on energy and mineral resources, or the erosion of social cohesion in our complex and overpopulated world. In other words, it is common if you insist on bringing reality into the conversation.

Our faith that progress is an arrow pointed ever upwards is a hard one to let go of—and we think of our save-the-planet work the same way—ever upwards, the best it has ever been, unquestionable.

But I say if what you are doing doesn’t work, it may be that you don’t need to do it Bigger! Faster! and Harder!

Maybe it just doesn’t work.
Maybe we need to do something different.

So the next response, “You want us to live in caves.” Obviously. Because different equals caves.

I don’t want to live in a cave. In fact, I want to live in a Jetsonian future in which our wondrous technology has liberated us from work while eliminating environmental impact, allowing us to truly find our place in the ecosphere alongside the splendiferous flora and fauna from tiny to titanic. I could be free to pursue something I am actually good at, like designing things.

But if you can stick with reality long enough, you start to realize that living in caves is a plausible, if undesirable outcome, whereas the likelihood of a Jetsonian utopia is that small speck you see disappearing over the horizon.

To review, the concentration of CO2 in the atmosphere is higher than it has been for millions of years, and we are well past the Paris Agreement target of 350 parts per million. Anybody who can bear to look at a chart of the global energy mix can see that renewables are not going to replace fossil fuels, even if we do have the resources, energy and social will to divert significant portions of our focus to windmills and solar panels. Which we don’t.

Add on to this an evergrowing population, many of whom are quite rightly pissed off at the level of exploitation their people and resources have experienced. They would like a piece of the pie, and are getting more aggressive about taking it.

Meanwhile, perhaps thanks to climate chaos, the breadbaskets of agriculture are facing persistent drought, while simultaneously being constrained by suburbia.

Our fragmentation of the biosphere is doing plants and animals no good as extinction rates are reaching asteroid-impact levels.


Living in a cave starts to seem like a pretty reasonable response. So should we just give up, then?

No. Giving up is not reasonable. But my father quotes an old hippie saying, “When what you’re doing isn’t working, try anything else.”

And I agree, though I think we can narrow “anything” down quite a bit.

There are three practical things I always suggest—walkable communities, well-insulated homes, and local food.

Our future is going to be much less fossil-fueled, either because we actually choose to stop killing ourselves with oil, or because the disruptions to the ecosphere—the primary source of wealth—finally impact the economy so drastically that we end up in a Greatest Recession. Either way, that is going to mean colder homes and fewer cars.

This will also impact the ridiculously energy-intensive industrialized agriculture system we have now, with huge satellite-controlled tractors, trucks, planes, and climate-controlled storage warehouses.


To those three practical things I would add a fourth activity, less palatable for the solutions-oriented crowd—grieving.

Grieving is a skill we have ostracized in North America, and yet there may be no skill that will be in more demand. Foreshadowed by the images coming from drought-torn Syria, the famine building in Nigeria, Somalia and Yemen, or by nations slowly disappearing beneath rising sea level, we will see a lot of death and loss.

Extreme weather is becoming more common even here in North America, with events that already sound positively apocalyptic. Again, people will die. Homes and memories will be lost, livelihoods destroyed.

And that is just if it doesn’t get any worse.

Despite our best attempts to banish unpleasantness we actually do have faint memories of how to grieve for those people and places we love. I think the worst pain we may face will be from our loss of progress, our loss of the promise that the future will keep getting better.

There is no brighter future.

It is enough to make you wonder if you have done anything worthwhile with your life; and that question does not feel good for anybody.

Anyhow, there is plenty to do, and none of it requires living in caves.


There is one more consideration I would like to ask you to keep in the front of your mind. We don’t have a lot of time, and we have fewer resources.

It would be really great if we didn’t waste them. 

So, I like to think about failure. There is an example I heard once—it was a joke actually, from a time when internet memes were shared as email footers.

It said, “When an escalator breaks down, you still have stairs.”

An escalator is failsafe; it fails-safe. It fails-useful.

Compare this to an elevator. An elevator fails-dangerous—it is useless, maybe even a deathtrap.

As we become ever more frantic to fix the predicaments we have created, we will grasp on ever more wild-eyed schemes.

So how will they fail?


The failure of one small farm among thousands is not severe, whereas the failure of GMO crops could impact millions of tonnes of food. The whizbang vertical farms will pour millions of dollars down the drain when they fail. Globalized food systems require multiple systems to not fail—finance, legal, shipping, maybe refrigeration.

An elevator becomes a useless box. But without an elevator, our glittering towers also become useless boxes since few people can climb above four or five floors. Imagine a time of cascading failure, and think of all the concrete, steel and glass wasting away in the sky. Think of all the carbon embedded in all that material, all of the lives spent building these sparkling follies.

As failures cascade, we will weep to see our electric cars immobilized, the asphalt cracking from age on roads travelled mostly by people walking and riding bikes. So much steel, so much aluminum. So many batteries and computer chips. The breakdown of our Space Age fantasy of electric cars will strand incredible assets and waste the embedded energy and labour.

Yet a walkable community remains walkable.

If the heater in a super-insulated house fails, you are still warm.

When your bean crop withers, step to the next row and console yourself with a fresh carrot.


Maybe I will offer one more bit of advice for our sunset years. Again, not mine, but not an email footer either. It comes from my friend J.B. MacKinnon, who counselled me, “Drink enough Scotch, but not too much.”




Sustainable means able to be sustained, and the alternative, then, is things that are unable to be sustained.

What part of unable to continue suggests we continue right down the same path? It is like my whole culture is gaslighting me because I feel so crazy.

Putting a finer point on it, I have long been a critic of vertical farms, most recently in Vertical farms: the greatest hope for cities, or a band-aid on a sucking chest wound? 

Salon also posted Enough with the vertical farming fantasies: There are still too many unanswered questions about the trendy practice.

But over at TreeHugger today, the tireless Lloyd Alter gives vertical farms a little love after nearly a decade of criticism, with I was wrong about vertical farms; Aerofarms shows how to make them really work.


Aerofarms has apparently avoided many of the things Lloyd has criticized in the past: the farm is in an abandoned factory, the growing racks are stacked very high to get more square footage, the plants are grown hydroponically in a fabric medium so consumption of nutrients and water can be tightly controlled to eliminate waste, and LED lighting is used that can be tuned to the specific colours the plants need for optimal photosynthesis, thus reducing energy use.

Aerofarms is a classic Less Bad is not Necessarily Good solution, in which efficiency serves to distract from the finitude of our planet.

Falling from 500 feet may be “less bad” than falling from 1000 feet, but you are still dead momentarily after impact. 

Today, we spend 10 calories of fossil fuel energy to produce one calorie of food. Efficiency might allow you to use eight calories of energy to produce one calorie of food, but you are still losing net energy at a shocking rate. It is Not Good.

Before fossil-fueled farming, it was easy to see which farmers used more energy than they produced—they were the dead ones. With only their own or their animals’ muscles to power a farm, the chain of cause and effect was very direct.

In Salon, Stan Cox calculates:

producing America’s annual vegetable crop (not counting potatoes) in vertical systems under lights would require well over half of the electricity this country generates every year, and that would crank out 1.3 billion metric tons of carbon emissions per year.

Half of the electricity?! Hey, let’s be generous and assume they can double efficiency! Then it will only take ONE-QUARTER of all the energy used in the United States. And that is before we “succeed” in electrifying transportation and heating and cooling, thus radically increasing demand for electricity.

Which quarter of your energy use are you going to give up? Oh, you don’t want to give anything up? All right, I guess we need to increase capacity by 25%…

So, just a quick check-in on the facts:

  • The US energy mix is 90% non-renewable, while globally, energy used is 80% non-renewable. Replacing that energy with renewables is going to be a significant challenge—a challenge many analysts characterize as impossible.
  • Various IPCC reports and international accords agree Greenhouse Gases need to be cut sharply and very soon. 80% reductions by 2050 is one common target.
  • Even still, these 80% reductions are widely seen as inadequate to avoid catastrophic climate change.
  • James Hansen predicts a sea level rise of several meters in the next 50-150 years. His position is controversial, but he has a history of conservative conclusions.

Given these facts, let me sketch some vertical farm scenarios regarding the electricity used to power the lights, pumps and filters, and whatever CO2 producing devices they are enriching the atmosphere with:

Dark Green Reality
In this scenario, let’s assume we look at whole systems and determine the most important response to climate change is to radically slash material and energy use. Energy is allocated with great care to only the most important tasks, like the digital archiving of certain very valuable research texts, powering infant incubators, and very small amounts of pumping and other services.

Since sunlight falls on fields for free, it is immediately obvious that generating electricity to power lightbulbs to grow salad is a fool’s choice. Humans choose a more local and seasonal life, following and obeying the rhythms of nature. Birds chirp in every tree.

Bright Green Utopia
The electrification of the ‘developed’ world accelerates, with champagne corks popped for every new Tesla model. The developing world follows, with electric cars, air conditioners, televisions, light bulbs and computers reaching billions more people then ever before.

To power all this requires damming every trickle of water on the planet, while resource extraction and manufacturing for solar panels and windmills still need huge amounts of fossil fuels. Coal plants stay online to cope with differences between demand and renewable supply (caused whenever the sun goes down), and there is a huge surge in (non-renewable) nuclear power development. The downwind pollution from nuclear reactors and fuel mining continues to cause cancers and birth abnormalities, and the spent fuel continues to have no place to be safely stored for the lifetime of the danger. It takes a century, but Aerofarms factory is washed away by rising sea levels.

Hell in a Handbasket
Increasing climate chaos activates human lizard brains at a mass scale, causing people to double down in a hedonistic fuck-it—a sort of perpetual Black Friday riot. All of this consumption requires massive amounts of electricity, so coal plants are spun up to maximum and construction starts on dozens of nuclear plants, as well as fuel mining and processing plants.

Global average temperature soars, ice caps suffer catastrophic melt raising sea levels dozens of feet within decades, not centuries. One billion people are displaced and massive urban areas including New York City and Mumbai are inundated. Aerofarms original location is washed away.

Business as Usual
On our current trajectory, BAU is not wildly different from the Hell in a Handbasket scenario.

There is no way to make vertical farms good. Neither our current model of transporting food great distances nor vertical farms are good responses to overpopulation and urban concentration. Maybe they are less bad. Maybe.

The public discourse, politicians, academics, journalists, scientists, most seem to be blithely washed along in the flood of business-as-usual. The plan—the actual policy—seems to be hoping a knight in shining armour will ride in to save us. This is enormously frustrating for me.

“Would you like to get kicked in both knees, or just one knee?”

“Erm…. I would like to not be kicked at all…”

We are talking about systems that rely on non-renewable resources, and are therefore impossible to sustain. The immutable forces here are the laws of nature. If our agriculture is not sustainable, that means it will not be sustained. That means it will end. That means people cannot eat it.

Less Bad is slow death.

But it is true, talking about what is Less Bad and what is Good obscures the reality of the situation a little.

The challenge is that while Less Bad is slow death, Good is increasingly looking like different death, at least in the short term. We show no sign of voluntarily realigning our society and our culture to follow the laws of nature. Rather, we continue to throw energy, materials and technology at problems. This makes a reckoning inevitable, and it is hard to see how an involuntary reduction in population can be avoided. It sure looks like truly sustainable agricultural practices that could feed humanity will only be widely adopted when we have exhausted all of our Less Bad options.

Now, slowing bleeding is always a good idea, but we are way past the cut and scrape stage. When medics perform triage after a catastrophe, they leave some people bleeding because they have no hope of survival and the bandages and personnel are needed for people who might live.

So, should we focus time and attention on infrastructure that, as these rough scenarios show, cannot endure? Personally, I try to work for things that are Good.

Which is not vertical farming.

Joseph Tainter on Complexity

I developed my understanding of sustainability essentially by hyperlinking books. I would read a book, then go through the citations and find another interesting book. This led me through design and ecology and economics and psychology and business and so many other things. At some point a pattern started emerging, and new bits and pieces began to fit into the pattern—each Piece of the Puzzle is something that has really stuck in my mind.
Not in chronological, or any other, order—just as the whim strikes me.


Joseph Tainter came to me relatively recently, maybe just in the last four or five years, but I find his work on complexity to be shockingly important.

He is an academic, so he does not lack for detail, but here is my favourite part in a nutshell:

We tend to solve problems by adding a layer of complexity to the situation. That new layer creates its own problems, which we solve with another layer of complexity. Each layer suffers from diminishing returns, and—here is the kicker—adding complexity eventually generates negative returns.

So, adding complexity eventually sucks value out of life, your project, our planet—everything. Here is a chart of what that looks like—Level of Complexity on the bottom axis, and Benefits of Complexity up the side axis:


Tainter’s big book is the Collapse of Complex Societies, which I found to be a very enjoyable read with lots of great examples. Here is a 15 minute interview and a 90 minute YouTube. Ugo Bardi looked at the thermodynamics.

“A collapse is a rapid simplification of society. It is a rapid loss of complexity.” So Tainter asked, “One of the questions of history is why is this seemingly inexorable trend in human society towards innovation and complexity occasionally punctuated by collapse?”

Having worked as an industrial designer, I have had a front row seat to the manufacturing supply chain—a very visceral view of how complex and brittle the systems we have built our world out of truly are. When you look around the world, you can see the negative returns all around us:

  • build a highway to fix congestion—which doesn’t fix the congestion, but does drain the pothole budget, so all the other roads get worse.
  • require playgrounds to have soft surfaces to reduce injuries—which increases the costs and reduces the number of playgrounds.
  • agriculture is a big one—chemical agriculture is used to boost production, but eventually destroys the soil so nothing can grow there.

Tainter also takes on the most sacred of cows, Innovation. He points out that innovation is also subject to diminishing returns—the first flush toilet was seriously awesome, but figuring out how to put custom finishes on toilets is much less remarkable.

In fact, if we are to maintain the illusion that indefinite growth is possible, we need ever-faster innovation cycles. Product design cycles used to be a couple of years, then one year, then six months. Now in some industries the design cycle may be just a few weeks. But we must go faster if we are to stay in the same place—soon we will be conceiving of, designing, prototyping, manufacturing and releasing products, all in the blink of an eye.

Except, of course, that is clearly impossible. So Tainter, with his modest puzzle piece, manages to skewer bureaucracy, complexity, collapse, innovation and growth. Phew! Heavy hitter!

So what next? “Now that we can do anything, we must do less.” When we are solving problems, we must try to find simpler solutions, rather than complex ones. How can we strip away bureaucracy, technology and data? How can we build a system simple enough to be understood and operated by its users?

Britain loses the potter’s wheel.

I developed my understanding of sustainability essentially by hyperlinking books. I would read a book, then go through the citations and find another interesting book.

At some point a pattern started emerging, and new bits and pieces began to fit into the pattern—each Piece of the Puzzle is something that has really stuck in my mind.

“It may be initially hard to believe but post-Roman Britain in fact sank to a level of economic complexity well below that of the pre-Roman Iron Age.”

Writing about this in the Archdruid Report, John Michael Greer said:

Good pottery was so cheap and widely available that even rural farm families could afford elegant tableware, sturdy cooking pots, and watertight roof tiles.

Rome’s fall changed all this. When archeologists uncovered the grave of a sixth-century Saxon king at Sutton Hoo in eastern Britain, for example, the pottery found among the grave goods told an astonishing tale of technical collapse. Had it been made in fourth century Britain, the Sutton Hoo pottery would have been unusually crude for a peasant farmhouse; two centuries later, it sat on the table of a king. What’s more, much of it had to be imported, because so simple a tool as a potter’s wheel dropped entirely out of use in post-Roman Britain, as part of a cascading collapse that took Britain down to levels of economic and social complexity not seen there since the subsistence crises of the middle Bronze Age more than a thousand years before.

These shards of British pottery are an X-ray of Infinite Progress—the government, or scientists, or corporations or whatever will not always ‘figure it out’. Once you accept this notion, you can see decline all around us, despite the latest offerings of apps, home renovation shows and refractions of celebrity.

There is a habit of not-thinking that says if something is wonderful we will surely figure out how to keep it going—to which I like to point out the potter’s wheel has one moving part. This is not complex technology and the benefits of using it are very great—and yet despite the simplicity and reward, Britain lost the wheel for 300 years.

This not-thinking is obvious in discussions of the internet. Because at least 0.01% of internet traffic is ‘causing’ revolutions in countries without democracy, it therefore follows the internet must last forever. I like to say the Internet is Just a Fad, as I commented in another column by The Archdruid, The End of the Information Age. The internet is the sharp peak of a very large pyramid of mining, refining, manufacturing, research, marketing, and—in case we forget—stoking the hell-fires of coal-powered electrical generation.
