The Limits to Growth –are we there yet?
The “experts” are all telling us, reassuringly, that the global recession is over and it won’t be long before we are back to the good old days of hedge funds, derivatives, Ponzi schemes, corporate bankers’ mega-bonuses, Hummers and, the biggest whopper of all, full employment. If these prognostications are correct we must assume that these “experts” know what caused the economic crash in the first place. No one, and especially former US federal reserve chairman, Alan Greenspan, has shown anything but complete surprise that the whole house of cards actually collapsed so precipitously – it didn’t fit the model he had in his head, he explained.
The unasked question is: What if we have reached yet another of those elephants in the garden that we have become so adept at not seeing? What if we have we reached the limits to growth?
Everyone knows that nothing, absolutely nothing, can grow forever. Ask your child or your aging grandparent whether they believe that infinite growth is possible and chances are that, like our economic experts, they haven’t actually thought about it - but common sense tells us that no, nothing actually does. Wait a minute, there is one very relevant example of unlimited growth isn’t there, the cancer cell.
The concept of “Limits to Growth” has been around for a long time, going back to political economist Thomas Malthus, but was particularly hi-lighted in a report by a global think tank known as the Club of Rome, founded in 1968. The report was published in 1972 and the two major conclusions follow:
1. If the present growth trends in world population, industrialization, pollution, food production, and resource depletion continue unchanged, the limits to growth on this planet will be reached sometime within the next one hundred years. The most probable result will be a rather sudden and uncontrollable decline in both population and industrial capacity.
2. It is possible to alter these growth trends and to establish a condition of ecological and economic stability that is sustainable far into the future. The state of global equilibrium could be designed so that the basic material needs of each person on earth are satisfied and each person has an equal opportunity to realize his individual human potential.
What if the economic collapse we are presently experiencing is a warning shot for worse to come, courtesy of Mother Nature? No satisfactory explanation has been forthcoming as to why everything went down the plughole so far and so fast, unless you accept the one about banks lending money to people who hadn’t snowball’s chance of paying them off. This was a symptom, not a cause.
It’s not as if we haven’t observed any of the ecological consequences already, we have simply chosen to ignore them. A trite excuse, often trotted out after a massive oil spill or yet another of those pesky species extinctions is, “Well, you can’t make an omelet without breaking a few eggs”. We all accept placidly that “progress” must continue. But is it really progress when the very pillars of human existence – clean air, potable water, healthy soils - are being toppled on a daily basis with no guarantee that they can ever be restored?
Is it progress when, year on year, there are more starving people or the planet, fewer forests on the land and less fish in the oceans? Why do we speak of “the good old days” but make no effort to redeem them? Sure, we don’t die from the black death or polio anymore – at least in western counties – but we do complain about mental depression, family breakup, traffic jams, urban smog and the ubiquitous speeding up of everything.
The second paragraph from the Club of Rome report is optimistic that things can be reversed and we can actually live sustainably. But the cultural changes that are necessary go totally counter to the trends of the last century which are premised on the belief that we can do whatever we want, and there are no consequences. It’s as if we have not evolved as a species beyond adolescence and, unfortunately, the human race doesn’t have an equivalent of parental guidance to restrain our impulses.
One prescription for the economic meltdown blues is that we move to a Green Economy, although a clear definition of this is not yet forthcoming. The only thing that can be confidently said about greening the economy is that it will be a lot like going back to the future. The old way of living in cooperation with the natural order kept humanity going for about a million years without our self-destruction - perhaps it would be wise to take note of that.
However, there are clearly certain directions that humanity must take if we hope to stick around or, more critical for the present, return to a solid economic foundation:
- End our dependence on fuels that were sequestered in the earth millions of years ago: bring back mass public transit, walk, bike, eat low on the food chain, insulate our homes, travel less and travel sustainably .
- Learn to live within our ecological footprint: stop making consumption our life purpose, refuse waste, eat and live locally.
- Aim for a steady state (zero growth) economy: stop using the antiquated measuring tool, the Gross Domestic Product, (GDP) that got us into this mess in the first place and adopt something that truly reflects human well being, the Genuine Progress Indicator, (GPI).
One of the main proponents of the GPI is an economist who lives right here in Edmonton, Mark Anielski. His best-selling book, called The Economics of Happiness, shows us how the GDP is clearly not serving us at all well. By putting a monetary value on everything from the Exxon Valdis spill to your last heart attack, the GDP is not a valid or accurate indicator of human progress. Alternatively, the GPI has pluses and minuses – after all shouldn’t we be measuring good health as a credit and deforestation as a debit?
So are we at the limits of growth? To answer that, simply ask the following questions:
- Will we be able to continue creating ever more land-fills, putting every kind of stuff (toxic and otherwise) into them for our grandchildren to sort out?
- How many rivers not reaching the ocean can we tolerate before the alarm goes off?
- At what point do we recognize that destroying the forests of the world to wipe our backsides is really stupid?
- When do we realize that what we laughably refer to as food is hardly distinguishable from the packaging that it comes in?
- Is it really wise to continue the uncontrolled experiment of pumping heat trapping gases into our atmosphere without considering that there just might be some adverse consequences?
- How much land should we give over to concrete and asphalt before reaching a point where there is nowhere left to grow food?
- Is it fair that we 20% in the west control 80% of all the worlds resources, whilst the other four fifths scratch out a living on a few dollars a day – and bear the major burden of ecological collapse?
- How many species have to disappear before we start to notice they are gone?
If these few questions can be reconciled and the conscience remains clear, then perhaps we haven’t yet reached the Limits of Growth. However, for the significant and growing minority of those who lose sleep over such conundrums, who are worried that without a radical reshaping of society we are setting ourselves up for a bleak future, for these people we are rapidly descending into a hole from which it will be impossible to get out of.

Sustainable Development
Great post David. I'm wondering whether you saw this thread about CASSE where we discussed steady-state growth. Also, have you read the Sustainable Development Commission report? I've given up advocating for CASSE amongst the GPC (because the CASSE position is not clear enough and is open to misinterpretation), but the thread is worth reading. Erich drew my attention to this excellent article that discusses measurements we need to live within: New doomsday map shows planet's dire state (popular press) / A safe operating space for humanity (original article).

Entropy in Sustainable Development
As far back as 1973 Linder and Nyberg created a simplified schematic flow-chart (can’t paste onto a blog) illustrating the contraction of the ‘Natural Ecosystem’ by our ‘Techno-system’ plotted over Time. The eco-mass is increasingly reduced in two ways; removing resources and dumping non-assimilatable waste back into it. Extrapolating the two curves; the consequences were the extinction of the ecosystem and life. The logical strategies to prevent this occurrence are not surprising:
1. Reduce rate of extraction of raw materials and overall consumption.
2. Maximize reuse and recycling; to minimize waste.
3. Use Environmental engineering change-over processes, enhance biodegradation or convert waste to allow re-assimilation into the ecomass.
What’s missing in this qualitative strategy is the essential role of energy and entropy. In order to recycle, reuse and especially convert waste into material that can be re-assimilated quickly by the ecosystem, entropy must be overcome. (2nd law of thermodynamics: a system will always go from a state of order to disorder. Meaning that a system will always ‘run-down’ in a way that is irreversible. Characterized by ‘energy dispersal’.) To overcome entropy, ever-increasing amounts of energy must be used. A cause for pessimism.
However recent peer-reviewed findings have shown that in Nature there are ‘pockets’ in the Universe (both macro and nano) where entropy is reversed. Biological life itself is order-out-of-chaos, and growth of an organism or a species is energy collection rather than dispersion. Its like an eddy or counter-current in a flowing river. Planet earth is one of those pockets. And the constant source of energy which permits this reverse phenomenon is the sun.
Unfortunately the accelerated rate-of-change produced by our technosystem has outpaced the former somewhat steady-state system on our planet and pushed us in an entropic irreversible direction. Only by harnessing much more of the solar energy and/or discovering benign sources of energy will we be able to overcome entropy and re-engineer our systems and waste into material that can be assimilated by the ecosystem at a rate equal to our reduction of it.
Life reverses entropy
Thanks Scott,
I always believed that life is couner to the entropy problem. Then someone told me that is not true. Thanks for putting th record straight.
DJP
Entropy.
Using entropy as a useful measure of macro effects of a macro-system is not helpful, especially if the system is not isolated.
If I throw trash in a pile of more trash, am I specifically increasing or decreasing entropy (locally)? I guess it depends on the trash; hence, it is not a good measure.
Schrödinger
You can give credit to Schrödinger (of 'wave equation' notoriety. Remember the equation that made you decide to drop physics?) who demonstrated that Life was negative entropy. Some have argued that the order life creates is at the expense of creating more disorder in its surroundings. But order and disorder are not fully defined, and this still does not refute the fact that biological life does collect energy rather than disperse it. I tend to side with Schrödinger, a genius who mastered quantum mechanics and probability (which is at the heart of entropy).

I meant to reply to you, David Parker, thx
What the f* is entropy?
Just kidding, the above post was very informative and explains a very important concept in ecological economics(as opposed to neo-classical and environmental economics), that of "entropy." For those who don't follow the academic description, perhaps the concept could be better explained through song, best done by MC Hawking (as in Stephen Hawking):

I post this in the hope of raising the overall knowledge of such topics among Green Party members.
As for the schematic flow chart, if you can't post here can you at least post a link to it somewhere?

Schematic & Summary
Thanks Matthew. I can scan it from hard-copy, but need a website to post it, or an email address to attach as a copy.
In conclusion, there are essentially 3 elements needed to achieve sustainable development:
1. Leadership. In order to effect an industrial transformation in the short time we have left before the system goes past the point of no return; a combined effort including, public, business and government working together is needed. (Similar to the war effort for WWII)
2. Ingenuity to Re-Engineer our industrial systems.
3. Benign sources of Energy to power them.
Entropy
The above statement on the second law of thermodynamics is not correct. The second law can be expressed in a number of ways but states that in an isolated system processes will act to increase the entropy of the system ("randomness or free energy") untill it achieves a state of equilibrium marked by a cesation of the increase in entropy. In nature there is no such thing as an isolated system actually. Some might say the earth is isolated but we have energy inputs from the sun and matter inputs from meteorites etc. The "isolated system" is a theoretical object. In essence in order to reverse the natural tendency of increased entropy on a specific process some form of work or energy must be applied.
Sorry, it wasn't a
Sorry, it wasn't a definition, but was meant as a helpful ‘description’. Currently there's alot of scientific debate on; randomness, disorder, order, and entropy as applied to the Cosmos and its sub-systems. (One measurable definition of entropy is the limit of an isolated system’s ability to do ‘work’. This avoids the difficult to define concepts of order and randomness.) As you correctly say, there is in fact, no such thing as an ‘isolated’ system, its always an idealization to some degree. I’m not sure what practical purpose it would serve to engage in this kind of technical debate for our ecological applications.
In any case, you have agreed, that in order to reverse the natural tendency for entropy, energy has to be applied. That is why I am suggesting the three elements necessary to create a sustainable ecosystem-technosystem symbiosis. Which I hope is our objective.
