Do We Really Want to Save a Place for Our Grandkids? It Sure Doesn't Look That Way.



It's claimed by those who study such things that civilizations that collapse do so suddenly and while they're at their peak.  In a way the process resembles a balloon bursting.  It gets bigger and bigger and then - pop.

How are we to know when we're nearing that civilization bursting point?  My theory is that we can see it when we reach the point where we simply ignore perils and challenges because we don't want to change.  It's looking as though we're there.

Britain is hosting the G8 summit now underway.   As host, the Brits get to decide what's on the agenda.   Syria is on the menu, so is North Korea.  The Cameron government, however, refused French and German requests to include climate change on the agenda for discussion.   There'll be no talk about the unhappy health of the biosphere this year.

Before we get too self-righteous, let's recall that we're not having much of a climate change conversation at home either.  The Petro-Cons shun that like the plague lest it infect their designs for bitumen peddling.   When it comes to the opposition New Dems and Libs, if climate change exists as an issue at all, it's buried somewhere near the bottom of their priorities and not particularly likely to surface until, eventually, it drives its way upward (and it will).

Which brings me to a paper published in The Proceedings of the Royal Society in January, "Can a Collapse of Global Civilization be Avoided?" by Stanford profs Paul and Anne Ehrlich.

"...today, for the first time, humanity's global civilization—the worldwide, increasingly interconnected, highly technological society in which we all are to one degree or another, embedded—is threatened with collapse by an array of environmental problems. Humankind finds itself engaged in what Prince Charles described as ‘an act of suicide on a grand scale’ [4], facing what the UK's Chief Scientific Advisor John Beddington called a ‘perfect storm’ of environmental problems [5]. The most serious of these problems show signs of rapidly escalating severity, especially climate disruption. But other elements could potentially also contribute to a collapse: an accelerating extinction of animal and plant populations and species, which could lead to a loss of ecosystem services essential for human survival; land degradation and land-use change; a pole-to-pole spread of toxic compounds; ocean acidification and eutrophication (dead zones); worsening of some aspects of the epidemiological environment (factors that make human populations susceptible to infectious diseases); depletion of increasingly scarce resources [6,7], including especially groundwater, which is being overexploited in many key agricultural areas [8]; and resource wars [9]. These are not separate problems; rather they interact in two gigantic complex adaptive systems: the biosphere system and the human socio-economic system. The negative manifestations of these interactions are often referred to as ‘the human predicament’ [10], and determining how to prevent it from generating a global collapse is perhaps the foremost challenge confronting humanity.

The human predicament is driven by overpopulation, overconsumption of natural resources and the use of unnecessarily environmentally damaging technologies and socio-economic-political arrangements to service Homo sapiens’ aggregate consumption [1117]. How far the human population size now is above the planet's long-term carrying capacity is suggested (conservatively) by ecological footprint analysis [1820]. It shows that to support today's population of seven billion sustainably (i.e. with business as usual, including current technologies and standards of living) would require roughly half an additional planet; to do so, if all citizens of Earth consumed resources at the US level would take four to five more Earths. Adding the projected 2.5 billion more people by 2050 would make the human assault on civilization's life-support systems disproportionately worse, because almost everywhere people face systems with nonlinear responses [11,2123], in which environmental damage increases at a rate that becomes faster with each additional person.

...a future global collapse does not require a careful definition. It could be triggered by anything from a ‘small’ nuclear war, whose ecological effects could quickly end civilization [32], to a more gradual breakdown because famines, epidemics and resource shortages cause a disintegration of central control within nations, in concert with disruptions of trade and conflicts over increasingly scarce necessities. In either case, regardless of survivors or replacement societies, the world familiar to anyone reading this study and the well-being of the vast majority of people would disappear.

How likely is such a collapse to occur? No civilization can avoid collapse if it fails to feed its population. ...What are the prospects that H. sapiens can produce and distribute sufficient food? To do so, it probably will be necessary to accomplish many or all of the following tasks: severely limit climate disruption; restrict expansion of land area for agriculture (to preserve ecosystem services); raise yields where possible; put much more effort into soil conservation [3]; increase efficiency in the use of fertilizers, water and energy; become more vegetarian; grow more food for people (not fuel for vehicles); reduce food wastage; stop degradation of the oceans and better regulate aquaculture; significantly increase investment in sustainable agricultural and aquacultural research; and move increasing equity and feeding everyone to the very top of the policy agenda."

Wait, a minute.   Did they say "the very top of the policy agenda"?  As in policy, the very reason we have summits like the G8 conclave now underway?   But this stuff isn't making the agenda, even climate change can't make it onto the agenda.   We need policy but you can't have policy without the foundation of information, discussion and consensus.   And we've very deliberately choked the life right out of that process. 

"One key to avoiding a global collapse, and thus an area requiring great effort and caution is avoiding climate-related mass famines. Our agricultural system evolved in a geological period of relatively constant and benign climate and was well attuned to twentieth-century conditions. That alone is cause for substantial concern as the planet's climates rapidly shift to new, less predictable regimes. It is essential to slow that process."

The authors then confront the fossil fuel "double bind."   Avoiding famines requires intensive agriculture that itself is fossil fuel dependent and a major source of greenhouse gas emissions.

"Fossil fuels are now essential to agriculture for fertilizer and pesticide manufacture, operation of farm machinery, irrigation (often wasteful), livestock husbandry, crop drying, food storage, transportation and distribution. Thus, the phase-out will need to include at least partial substitution of non-fossil fuels in these functions, and do so without greatly increasing food prices.

...Rationalizing energy mobilization alone may not be enough to be enough to maintain agricultural production, let alone allow its great expansion. Human water-handling infrastructure will have to be re-engineered for flexibility to bring water to crops in an environment of constantly changing precipitation patterns [51]. This is critical, for although today only about 15 per cent of agricultural land is irrigated, it provides some 40 per cent of the grain crop yield. It seems likely that farming areas now rain-fed may someday need to be irrigated, whereas irrigation could become superfluous elsewhere, and both could change more or less continually. For this and many other reasons, the global food system will need to quickly evolve an unprecedented flexibility, never before even contemplated.

One factor making the challenges more severe is the major participation in the global system of giant nations whose populations have not previously enjoyed the fossil energy abundance that brought Western countries and Japan to positions of affluence. Now they are poised to repeat the West's energy ‘success’, and on an even greater scale. India alone, which recently suffered a gigantic blackout affecting 300 million people, is planning to bring 455 new coal plants on line. Worldwide more than 1200 plants with a total installed capacity of 1.4 million megawatts are planned [76], much of that in China, where electricity demand is expected to skyrocket. The resultant surge in greenhouse gases will interact with the increasing diversion of grain to livestock, stimulated by the desire for more meat in the diets of Indians, Chinese and others in a growing global middle class. 

Another possible threat to the continuation of civilization is global toxification. Adverse symptoms of exposure to synthetic chemicals are making some scientists increasingly nervous about effects on the human population [7779]. Should a global threat materialize, however, no planned mitigating responses are waiting in the wings ready for deployment.

(This is part of what Britain's Astronomer Royal, Martin Rees, eminent cosmologist and astrophysicist, refers to as the double-pronged threat of bio-terror and bio-error) 

Much the same can be said about aspects of the epidemiological environment and the prospect of epidemics being enhanced by rapid population growth in immune-weakened societies, increased contact with animal reservoirs, high-speed transport and the misuse of antibiotics [81]. Nobel laureate Joshua Lederberg had great concern for the epidemic problem, famously stating, ‘The survival of the human species is not a preordained evolutionary program’ [82, p. 40]. Some precautionary steps that should be considered include forbidding the use of antibiotics as growth stimulators for livestock, building emergency stocks of key vaccines and drugs (such as Tamiflu), improving disease surveillance, expanding mothballed emergency medical facilities, preparing institutions for imposing quarantines and, of course, moving as rapidly as possible to humanely reduce the human population size.

But much uncertainty about the human ability to avoid a collapse still hinges on military security, especially whether some elements of the human predicament might trigger a nuclear war. Recent research indicates that even a regional-scale nuclear conflict, as is quite possible between India and Pakistan, could lead to a global collapse through widespread climatic consequences [32]. Triggers to conflict beyond political and religious strife easily could include cross-border epidemics, a need to gain access to food supplies and farmland, and competition over other resources, especially agricultural water and (if the world does not come to its energy senses) oil. Finding ways to eliminate nuclear weapons and other instruments of mass destruction must move even higher on civilization's agenda [85], because nuclear war would be the quickest and surest route to a collapse [86].

Why a leader like Stephen Harper is absolutely the worst person at the worst time:

To our minds, the fundamental cure, reducing the scale of the human enterprise (including the size of the population) to keep its aggregate consumption within the carrying capacity of Earth [121], is obvious but too much neglected or denied. There are great social and psychological barriers in growthmanic cultures to even considering it. This is especially true because of the ‘endarkenment’a rapidly growing movement towards religious orthodoxies that reject enlightenment values such as freedom of thought, democracy, separation of church and state, and basing beliefs and actions on empirical evidence. They are manifest in dangerous trends such as climate denial, failure to act on the loss of biodiversity and opposition to condoms (for AIDS control) as well as other forms of contraception [122]. If ever there was a time for evidence-based (as opposed to faith-based) risk reduction strategies [123], it is now.  

The professors Ehrlich believe non-governmental organizations and other groups have an important role to play, perhaps not in the survival of our current civilization, but in the regeneration of the successor civilization.  How's that for blunt?  Absent the political will to enact meaningful policy, that might be the best bet we're left with.

"There are certainly many small-scale science-based efforts, often local, that can provide hope if scaled up [121]. For example, environmental non-govenmental organizations and others are continually struggling to halt the destruction of elements of biodiversity (and thus, in some cases, of vital ecosystem services [7]), often with success. In the face of the building extinction crisis, they may be preserving nuclei from which Earth's biota and humanity's ecosystem services, might eventually be regenerated.

Until very recently, our ancestors had no reason to respond genetically or culturally to long-term issues.  ...Societies have a long history of mobilizing efforts, making sacrifices and changes, to defeat an enemy at the gates, or even just to compete more successfully with a rival. But there is not much evidence of societies mobilizing and making sacrifices to meet gradually worsening conditions that threaten real disaster for future generations. Yet that is exactly the sort of mobilization that we believe is required to avoid a collapse.

Perhaps the biggest challenge in avoiding collapse is convincing people, especially politicians and economists, to break this ancient mould and alter their behaviour relative to the basic population-consumption drivers of environmental deterioration.   ...Obvious parallels exist regarding reproduction and overconsumption, which are especially visible in what amounts to a cultural addiction to continued economic growth among the already well-off [134]. One might think that the mathematics of compound interest would have convinced everyone long ago that growth of an industrialized economy at 3.5 per cent annually cannot long continue. Unfortunately, most ‘educated’ people are immersed in a culture that does not recognize that, in the real world, a short history (a few centuries) of exponential growth does not imply a long future of such growth.

Unfortunately, awareness among scientists that humanity is in deep trouble has not been accompanied by popular awareness and pressure to counter the political and economic influences implicated in the current crisis. Without significant pressure from the public demanding action, we fear there is little chance of changing course fast enough to forestall disaster

The needed pressure, however, might be generated by a popular movement based in academia and civil society to help guide humanity towards developing a new multiple intelligence [135], ‘foresight intelligence’ to provide the long-term analysis and planning that markets cannot supply. Foresight intelligence could not only systematically look ahead but also guide cultural changes towards desirable outcomes such as increased socio-economic resilience. 

Obviously, especially with the growing endarkenment, there are huge cultural and institutional barriers to establishing such policies in some parts of the world. After all, there is not a single nation where women are truly treated as equal to men.

That halting population growth inevitably leads to changes in age structure is no excuse for bemoaning drops in fertility rates, as is common in European government circles [141]. Reduction of population size in those over-consuming nations is a very positive trend, and sensible planning can deal with the problems of population aging [142]. 

...Do we think global society can avoid a collapse in this century? The answer is yes, because modern society has shown some capacity to deal with long-term threats, at least if they are obvious or continuously brought to attention (think of the risks of nuclear conflict). Humanity has the assets to get the job done, but the odds of avoiding collapse seem small because the risks are clearly not obvious to most people and the classic signs of impending collapse, especially diminishing returns to complexity [28], are everywhere. One central psychological barrier to taking dramatic action is the distribution of costs and benefits through time: the costs up front, the benefits accruing largely to unknown people in the future. But whether we or more optimistic observers [17,163] are correct, our own ethical values compel us to think the benefits to those future generations are worth struggling for, to increase at least slightly the chances of avoiding a dissolution of today's global civilization as we know it.

This paper reinforces my personal campaign for democratic restoration in Canada by progressive measures including dismantling the corporate media cartel that creates a powerful obstacle to the conversation we need to have as a people; wrestling inequality of all forms to the ground to rebuild the essential cohesiveness of Canadian society; and the rehabilitation of posterity as a key factor in government policy and planning, what the professors Ehrlich here call "foresight intelligence."  We need to do all these things not merely because they're the right things to do but because our very future and that of those who follow us absolutely depend on it.

"even a regional-scale nuclear conflict, as is quite possible between India and Pakistan, could lead to a global collapse through widespread climatic consequences"

The paper linked as a reference for this only predicts regional famines, not global collapse. Even then it compared local nuclear wars to volcanic events from hundreds of years ago when much more of the population was highly susceptible to famine.

DOC, there was a time, way back, when I had to learn the theories of nuclear escalation. That was even before we grasped the concept of "nuclear winter."

The trouble is, once you start using the goddamned things, beginning with tactical nukes, you shatter the taboo and afterward it becomes increasingly hard to stop the spread to secondary parties and larger, strategic weaponry.
