Infrastructure and its workings

The Origins of Infrastructure

One of the great mysteries of humanity’s history is how we made the transition from an isolated, emergent species to attain today’s globally dominant civilization. Scientists tell us that the story began as early as 7 million years ago in Eastern Africa. Fossils found in the Awash Valley give evidence of our early precursors. Archaeological findings suggest that some of these precursors began to fabricate and use rudimentary stone tools between 6 million and 2 million years ago. Learning to control fire followed about 1 million years ago. By 70,000 years ago homonins had migrated out of Africa and begun to apply more complex technology evidenced in hafted spears, for which a sharpened stone point was attached to the wooden shaft.

The fossil record indicates that our own species, Homo sapiens, evolved during this progression and became the sole survivor among several homonin species. The evolution included a remarkable growth in brain size as well as emergence of social behavior and technological prowess. Some scientists hypothesize an interaction between physical capability and intellectual accomplishment to explain this evolution.

British archeologist Steven Mithen, for example, surmises that early uses of technology (such as hafting of spears) encouraged development of “cognitive fluidity,” an ability to abstract and combine aspects of experience from different domains such as finding shelter or observing game.  The large brain of Homo sapiens was an essential adaptation that enabled this cognitive fluidity to develop, but does not by itself explain how the development came to be. Adopting and using a cultural innovation provides the stimulus for users to extract more from their brains than they might have otherwise.

Drawing on observations of ants and other animals that exhibit eusocial behavior and altruism—in which some individuals in a colony or nest limit their own reproductive potential by raising the offspring of other nest-mates or defending the group against competitors and predators—noted Harvard biologist Edward Wilson suggests that certain “preadaptations” favor the behaviors’ evolutionary development. Among the most important of these preadaptations, Wilson conjectures, is a species’ propensity for living in defensible nests.  When early humans, tribal by nature, learned to use fire and establish campsites sufficiently persistent to be guarded as a refuge, they had taken a crucial step toward modern social organization.

Wilson and his colleagues Martin Nowak and Corina Tarnita assert that the advantage of a defensible nest located within reach of reliable food sources, particularly one requiring greater energy in its construction, is a crucial causative agent in the evolutionary development of eusociality, a trait that loosely applies to humans as well as ants. A next step in humans’ social evolution beyond the adoption of movable campsites would logically seem to be long-term commitment to a fixed location. The earliest evidence of such commitment arguably is found in the Chauvet Cave walls in southern France.  Images painted on the cave walls here and elsewhere (for example, the El Castillo cave in Cantabria, Spain, and others Romania and Australia) are estimated by various archeologists and methods be 28,000 to 40,000 years old.

We have no convincing evidence of the creators’ motivations for any of the cave paintings, but their permanence and often difficult-to-access locations suggest these were not simply decorations of living space, but rather demonstrations of a particular significance of place, perhaps an effort to preserve human memory as recorded history. I propose that in this sense these ancient markings are humanity’s earliest known infrastructure.

University of Cambridge archaeologist Graeme Barker has presented the evidence suggesting that the domestication of various forms of plants and animals evolved in separate locations worldwide, starting around 12,000 to 14,000 years ago.  For many researchers, this domestication is synonymous with “agriculture,” a technological innovation and foundation of modern civilization.  An alternate model proposed by David Rindos in the 1980s proposed that domestication of locally available plants, a co-evolutionary interaction of humans and their food sources, led to intentional agriculture and consequent selection of preferred species and strains.

This domestication of plants has been characterized as the beginning of the Neolithic or Agricultural Revolution.  Evidence, particularly from the Fertile Crescent region in the Middle East, indicates that cultivation was accompanied by construction of settlements and drainage ditches and landforms to control plant irrigation.  Archeological studies by Harvard archeologist Ofer Bar-Yosef and others are currently thought to indicate that the Natufian culture in the region is the world’s oldest example of sedentary settlements and agriculture, notable particularly because the settlements may have preceded the commencement of crop cultivation.

Whether development of agriculture preceded or followed the birth of cities has long been debated.  Mithan, for example, reflecting recently on the progress of human civilization, expressed a widely held view that agriculture came first, and once farming had originated, towns and cities appear to be an almost inevitable consequence.  On the other hand, Jane Jacobs, an economist and unabashed urbanist, famously argued in the 1970s that labor specialization and trade first gave rise to cities, and that feeding their populations necessitated the development of agriculture. (Archaeologists notably disagree. See Smith, Michael E., Jason Ur, and Gary M. Feinman.  2014.    “Jane Jacobs’s ‘Cities-First’ Model and Archaeological Reality.” International Journal of Urban and Regional Research 38 (4): 1525-1535.)

In either case, however, it would seem that infrastructure came first. The investment of effort in clearing fields; moving earth to adjust water flow; building fences, protective walls, and substantial shelters; maintaining paths for transportation; and the like would have contributed substantially to agricultural productivity, settlement economy, and social functioning of the residents.

Learning to Live with New Infrastructure Technology

The headline in The Atlantic, responding to an earlier article in the New York Times, asks the question, “Are we addicted to gadgets or indentured to work?”  (“Silicon Valley Says Step Away From the Device,” Matt Richtel, 7/23/2012, Business Day, New York Times.   “Are We Addicted to Gadgets or Indentured to Work?” Alexis Madrigal, 7/24/2012, The Atlantic. 

Matt Richtel, writing in The Times, reports that leaders at influential Silicon Valley companies are growing concerned about increasingly widespread addiction to gadgets.  Our attraction to smart phones, tablets, and on-line living, some say, reflects “primitive human longings to connect and interact” that threatens to take over our lives.  Next year’s edition of the authoritative Diagnostic and Statistical Manual of Mental Disorders, Richtel writes, is slated to include “Internet use disorder” in its appendix, indicating that the mental health profession thinks there may be a real problem but needs more research to understand it.

Responding in The Atlantic, Alexis Madrigal asserts the problem—for Americans, at least—is our slavish devotion to work.  We—or the upper middle class that reads the Times, at least—is working more and “having to stay more connected to work than ever before,” forced by employers (with the help of “our strange American political and cultural systems”) to be on the job 24/7. Citing both Mother Jones and McKinsey Quarterly as inspiration, Madrigal suggests that we need not simply to tear ourselves away from our electronic devices, but rather “organize politically and in civil society to change our collective relationship to work.,” adopting a more European perspective on our who controls our time.

Whether their myopia has an ideological or technological basis, both writers are overlooking the fundamental influence of our infrastructure.  In past decades motorized transport and telephone service dramatically reduced the influence of distance as an obstacle to economic and social interactions. The demands of maintaining international business networks and global supply chains shifted our ideas about “banker’s hours” and the sanctity of holidays and weekends.     Radio and television brought education and diversion, evolutionary emergence of “couch potatoes,” and threats to book and newspaper publishing.  These new infrastructures also supported and arguably accelerated dramatic expansion of the middle class and service sectors of the economy.  These changes went hand-in-hand with accelerating urbanization of our population and suburbanization of our cities.

As difficult as it may be to believe, digital wireless communication and the devices we carry to take advantage of this new infrastructure have become widespread in just about two decades.  The technology enables me and my colleagues—all of us somewhere well below the infamous top 2% of the income curve—to work from virtually anywhere and to shift working hours.  No longer must I take an entire day off to attend to medical appointments, to have my car repaired, or to attend my child’s school play.

I view this as new freedom rather than a grasping employer’s imposition. Many workers do not yet enjoy such freedom and, as in the past, some jobs are not suited to such changes of practice.

Recent statistics show an international trend of younger people being slower than preceding generations to get their driver’s permits.  Citing a study by the University of Michigan’s Transportation Research Institute, for example, MSNBC’s Paul Eisenstein reports that American teens are not rushing to get a driver’s license as soon as they become eligible, and that another study found similar trends in seven of 14 other industrialized countries.  (“American teens are waiting longer to drive,” Paul A. Eisenstein, 4/9/2012, MSNBC, Bottom Line)  In their own analysis, the Dayton Daily News found a 9 % drop in Ohio’s 16- and 17-year-old licensed drivers from 2006 to 2010, and a 4.7% decline in the number of Ohio 18-year-olds with licenses.

Analysts suggest the Internet, meaning particularly such new social media and communication applications as Facebook and text messaging, may be a key reason for the change.  Whatever the reasons, Eisenstein writes that auto company executives are worried that the trend may signal future declines in new-car demand.  Transit advocates are using the data to argue for higher government spending on urban public transportation systems.

How many hours we spend commuting, whether those hours can be used for anything other than steering and avoiding mishap, and whether the hours otherwise spent are counted as work or leisure are topics for another time.  Only consider for now the possibility that any purported addiction to gadgets and commitment work are simply short-term byproducts of learning to live with new infrastructure.

“Sustainability” may be fundamentally unsustainable, but we have a chance

The idea of “sustainability” has clearly taken root.  The word appears frequently in print as well as Internet media, and national governments around the world have established agencies and programs devoted to it.  There seems to be widespread agreement that the idea has something to do with energy supplies, environmental impact, and economic growth, and perhaps with social engagement and political stability as well, although the scope of what is to be sustained—individual well-being, national prosperity, global status quo, for example—seem to differ from one forum to another.  However, there seems also to be a dawning realization that the idea’s application as a basis for guiding humanity’s actions may not be sustainable.

An important early appearance of the meme, if not its initial source, is often attributed to the World Commission on Environment and Development, commonly known as the Brundtland Commission.  This group of international experts was convened by the United Nations in 1983 to propose long-term environmental strategies for achieving sustainable development; recommend ways that concern for the environment may be translated into greater co-operation among countries; and help define shared perceptions, aspirational goals, a long-term agenda for action.  The Commission’s 1987 report, Our Common Future  suggested that “Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.”  Among the still-expanding literature on the subject, I have found no more cogent definition of the term.

It might seem like a small step from seeking humanity’s “sustainable development,” a steady advancement of people’s achievement and wellbeing, to the “sustainability” of humanity, our survival as a prosperous species.  For a number of reasons, however, I suggest there is a large gap between the two concepts.  The gap is so broad, in fact, that I doubt the value of sustainability as a meaningful basis for guiding our principles and policies. Let me explain why.

To begin, the time scale for thinking about our sustainability far exceeds our abilities—politically, socially, historically, perhaps psychologically—to plan, take meaningful action, or even pay attention.  Scientific evidence suggests that the biological genus of which humans are a part evolved into being and the first hominid use of stone tools began in Africa perhaps 2.5 to 3.5 million years ago.  Evidence of homo sapiens sapiens, our particular species, dates back about 250,000 years.  (In all of this, my phrasing is meant not to convey any skepticism, but rather to acknowledge that we rely entirely on inference from the limited data available to us to draw conclusions about past events and conditions.)

Our various experiments in culture, social, and political organization are rather brief when seen in sharp contrast with these time periods.  Damascus is often claimed to be the oldest continuously inhabited city in the world, but evidence for large-scale
settlement seems to date back only about 4,000 years. (The earliest Egyptian, Sumerian, and Chinese written records may have been created about 6,000 years ago.)  The community water-management schemes of Bali and other parts of Indonesia, arguably among the better models for sustainable relationship of humans and their environment, began to exist perhaps 1000 years ago.  England’s Magna Carta was first issued in 1215 and the United States, our ongoing experiment in capitalist democracy, was established less than three centuries ago.  Viewed against the backdrop of human history, “sustainability” has had a very brief span of influence.

In addition, there is the fundamental uncertainty of our existence as a species.  While some people prefer alternative explanations, the fossil evidence suggests that many varieties of creatures have come and gone since the first simple cells appeared.  The famously extinct dinosaurs died out, some scientists suggest, after an asteroid colliding with the Earth caused extreme global climate change.  On a less cosmic scale, scientists theorize that the ash from a volcanic eruption approximately 70,000 years ago at Lake Toba on the island of Sumatra, Indonesia, similarly caused such a dramatic global cooling that human population was drastically reduced.  Outbreaks of bubonic plague (the infamous Black Death of 14th Century Europe) and related famines in more recent times have dramatically reduced human populations in Asia and Europe.  Apart from simply not giving in to existential despair, probably the best we can do in light of such evidence is to limit our perspectives to decades at most.  Some government agencies already seem to be unable to maintain funding for the programs they established to enhance their communities’ “sustainability.”  (For example, see the commentary on Sustainable Cities Collective.)

Finally, we really cannot know whether our actions are “sustainable” with respect to either our development or our survival.  Application of the Brundtland definition requires forecasting not only the consequences of our current actions but also what future generations may judge to be their own “needs.”  On the one hand, our society and our global environment are a complex system, susceptible to the well-publicized “butterfly effect;” any small perturbation can cause unforeseen consequences.  On the other hand, our values, technologies, and culture change from one generation to the next, so that what may seem to us an inconsequential change may be seen very differently by our children; consider for example the shift in our views about air pollution pesticides.  In general then any assessments of the future consequences of our actions are more than likely to be inaccurate.  Even more fundamentally, it seems quite likely that we simply cannot do anything to meet our own present needs without in some sense compromising the options available to future generations.

While “sustainability” or even “sustainable development” may be problematic as directly useful concepts, the ideas nevertheless do point the way toward useable principles. Applying these principles will at least increase the chances of our long-term survival:

  • Use only renewable resources: No matter how large the supply reservoir may be, it will eventually be exhausted.
  • Eliminate all waste and pollution: What economists refer to as “residuals” are simply an indicator of inefficiencies in
    our production processes.
  • Stabilize our population: Increasing humans’ wellbeing and chances of survival as individuals and as a species depends ultimately on enhancing labor productivity as well as on applying strictly the first two principles.

Living without electricity

Living without electricity for a while helps to focus the mind on how we rely on our infrastructure and our ability—or lack thereof—to make reasoned choices about that reliance.  Hurricane Irene swept up the mid-Atlantic coast on a weekend, likely reducing the storm’s impact on most businesses.  Forecasters did a nice job, giving plenty of warning of the approaching winds and rain, and many people seem to have been prepared for some inconvenience.  The hurricane’s actual path probably reduced the amount of damage at actually occurred, at least until the eye of the storm went inland and through New England to produce devastating floods.

Even so, disruption was extensive. Amid blowing winds and a torrential downpour, the power went out at my house at about 3 am Sunday morning.  A neighbor reported seeing the flashes of what we assumed to be the pole-mounted equipment blowing as downed branches and trees shorted out the overhead wires.  Baltimore Gas and Electric (BGE), the utility serving us, reported that some 750,000 of its 1.23 million customers in the region lost service. The public relations folks claim that crews have been brought in from as far away as Kentucky to help with repairs.

At home and still without power more than 72 hours later, I am able to use my laptop and communicate with the world thanks to cellular telephone service and 100 feet of extension cord plugged into my neighbor’s house across the street. His side of the block did not fail.  We plugged in the fridge, have a gas range and good supply of candles; I must admit that many others are suffering much more than we are at the moment.

At least three aspects of the situation nevertheless bother me.

First there is the customer service.  While BGE messages to customers claim they are working “around the clock,” local news reports that the repair crews shut down for the evening at 8 pm; the statistics reported for restorations of power show clearly there was no overnight progress. Four days since BGE claims to have started storm operations, more than 20 percent of customers who lost power are still in the dark.  Our local food market could not open and had to throw away thousands of dollars’ worth of spoiled goods.  The planned Monday opening for the city’s schools had to be pushed back to Wednesday.  I don’t think it is unreasonable to expect the utility to work around the clock to restore full service.  I don’t think it is unreasonable to expect that parts and materials should be available within a 2-day period from other parts of the continent to accommodate these foreseeable emergency demands.  Yet I cannot take my business elsewhere and there is no apparent way that failures of customer service will influence the company’s profitability or its executives’ income.

Second is the facility system.  Electricity is delivered to my city neighborhood and much of the region by overhead wires. Many storms far short of hurricane intensity cause frequent power interruptions. (To the BGE’s credit, my impression is such outages tend to be fixed within 4 to 6 hours, regardless of when and under what weather conditions they occur; this seems to me a reasonable standard.  Why are utilities and other infrastructure providers not required to make their performance statistics public, with standardized definitions and measurments?) While my definitely-leafy part of the city is less dense than many, I do not really understand why the poles have not been retired and the wires placed underground.  I know the initial cost would be high, but I not convinced it would not be more than offset by the avoidable out-of-pocket and inconvenience costs I pay for recurring outages and reductions in the utility’s maintenance expenses. I suspect that the idea of moving to underground installations throughout the city is made unattractive by utility accounting and regulatory systems (increased investment in fixed capital), not to mention the public-relations and political headaches of using cutting into city streets or securing private easements and connecting to each house and shop.  Nevertheless, I believe we should not have to consolidate to Manhattan-style densities to warrant the investment.

Finally, there is the thought of what the future may hold.  If costs for such new technologies as fuel cells, photovoltaic installations, and wind-powered generators continue to decline, as I expect they will, I think small customers located in less-dense areas will decide to cut their ties to the power grid.  Large corporate utilities will deal primarily with large consumers, whether they be businesses or multi-unit residential cooperatives and condominiums. A future in which a large fraction of households can meet their domestic energy demands from locally-supplied sun, breezes, and digested grass clippings and leaf collection is arguably more sustainable than what we now have, but it does imply maintaining what many people now call “sprawl.”

Making infrastructure investment more attractive through consumption

I must have been offered at least a dozen credit cards in the past week, each one an opportunity to spend on clothes, electronic toys, food, travel, and other items for consumption. Each of the financial institutions hoping to attract my business was also hoping, I imagine, that I might by choice or chance not pay their bills in full and thereby convert my debt to a longer-term and high-yielding asset on their books.  I would be bound, according to terms typical of the offers, to pay interest on my unpaid balance at rates significantly above 10% annually, 5 to 10 times what the banks would pay me to lend them money by purchasing a certificate of deposit.

While I am certainly annoyed by the steady barrage of credit-card offers, particularly within the context of my recent memories of financial meltdown, mortgage crisis, and federal debt-limit bickering, my deeper concern is why are there no attractve offers to buy into my city’s or state’s or nation’s infrastructure.  With aging bridges and pavements, bursting water mains, and straining levees almost everywhere apparent in this country, the demand for infrastructure investment should be booming.  Meeting that demand—whether through private initiative or government action—would not only create immediate jobs in materials, construction, and facilities management, but also provide the services to support sustained growth in the economic sectors that depend on efficient transportation, clean water supply, and flood-free operations.  Can we create ways to make infrastructure investment—a good thing—as attractive and painless as—a bad thing—going deeper into consumer debt?

I think we can.  Here’s one idea.

Suppose a state government joined with an appropriate team of banks, utility companies, and local authorities, that is, form a serious public-private partnership. (PPP)  The PPP would begin by marketing an affinity-branded credit card and matching debit card.  The attraction for consumers using the cards would be a credit—say 3 to 5 percent of all purchases—to be applied against current infrastructure services (for example, transit fares; water, electric power, and natural gas fees; tolls and or parking fees), property and real estate transaction taxes, or purchase of tax-advantaged bonds issued by the government members of the PPP.  The bonds could be of the zero-coupon variety, to reduce the need for current cash flow and to encourage longer-term consumer saving.  Employers and utilities could use the card to store transit credits and demand-management incentives for employees and customers.

The cards’ branding could celebrate the social as well as physical infrastructure of the target market region. Card-holders would receive their credits only by using the card to pay for infrastructure services and taxes (or by investing in bonds), accelerating the trend toward reducing cash processing costs and revenue leakage.  The bankers gain access to a large population for associated marketing and data mining.  There seem to me to be a lot of winners in this scheme.

Feasibility seems proven.  Affinity cards and employee-benefit debit cards are well developed, of course.  There are rudimentary versions of what I am imagining in use, such as multi-system transit fare cards (Washington’s SmarTrip and Baltimore’s CharmCard), the E-ZPass highway toll-collection system, and the services offered by Toronto-based Skymeter.  While we are not likely to change from a consumption-driven economy, perhaps we can channel some of the consumption painlessly in savings, investment, and a sustainable infrastructure.

Sustainable Values and Infrastructure

There seems to be little question that we are now in one of those historically recurrent periods of societal crisis that tell us we must change our ways.  A plethora of recent books present dismal perspectives of our clash of cultures, changing climate, losses of species and languages, and financial crises, and how each threatens our well-being and lastingness.  The threats are very real, of course, but to me are interesting because, if relief is to be found, surely our infrastructure must have an important role.

Seeking to understand this role, I have finally plowed my way through Raj Patel’s modestly titled exegesis on modern economics and human nature, The Value of Nothing: How to Reshape Market Society and Redefine Democracy. (2009, New York: Picador)  With ample reference to both foundational and more radical texts of market economics and Western social theory as well as more personal accounts of current populist movements, the book has definitely generated buzz and expanded its author’s reputation to sometimes messianic proportions.  (For a review, see “Are You the Messiah? A political economist gets a following he wasn’t expecting,” by Lauren Collins, New Yorker magazine, November 29, 2010)

The reading took longer than expected, because as page after page turned I felt compelled to pencil in questions, opposing references, and outright objections to Patel’s perspectives. Where he sees elemental democracy in the masked pronouncements of a Zapatista Junta, I see the tyranny of the mob. When Patel disparages the possibility of getting prices right—or having any prices at all—for clean air and water, I despair at the idea that humans will forsake the desire to improve their lives, however privileged they may be, satisfied that their needs—defined by others—are being met. While Patel finds it essential to feed the world’s growing population by rationing necessarily limited food production, I wonder why humanity might not be happier and arguably better off limiting population to levels supportable with an abundant and varied food supply.  I suppose I must recommend the book at least because it offers the attentive reader ample intellectual stimulation.

Patel’s message seems to be that for two key reasons a market-based, democratic society is essentially unsustainable and revolutionary change is essential. First, there is no hope of getting the prices right for clean air, pure water, cultural diversity, historic associations, and myriad other resources we humans use in pursuit of comfortable lives. Second, our abilities as humans to work together toward success in this pursuit are hopelessly subverted by the existence of corporations, disembodied entities that behave with the legal rights and powers of a person but lack a person’s moderating moral and ethical judgment.   Without the restrictive forces of either appropriate prices or moral imperatives, corporations and people ruthlessly seek exclusive control of collective resources and private gain from exploitation of these resources.

Hope lies, for Patel, in a Buddhist theory of value.  “The real value of something,” he writes, “is not its ability to satisfy a craving, a desire, a vanity, but to meet the need for well-being.”  With enlightenment, we will recognize that our desire for cell phones, shoes, and other such “baubles and fripperies” is nothing but illusion created by hidden persuaders.  Corporations will somehow adapt, I suppose, and we will lose our lust for more, all settling happily for just “enough.”

British economist Diane Coyle’s book The Economics of Enough: How to Run the Economy as if the Future Matters. (2011, Princeton, NJ: Princeton University Press) takes a similar stance on the problems but offers a more moderate assessment of the underlying issues and, to my mind, a more practical prescription for what must be done.  She focuses her attention on the inevitable necessity of making tradeoffs among efficiency, fairness or equity, and freedom in how people are able to pursue and manage their resources.  Our values and our governance, as individuals and groups within our society, determine how the balance is struck, and today we have “tilted too far”—in Coyle’s view and my own—“in favor of individualism and the gratification of immediate wishes,” toward freedom at the expense of fairness and even efficiency. Where previous generations made investments, we now are consuming our assets.

Regarding values, Coyle’s views are not so different from Patel’s: We need a change of values to guide our behavior.  In Coyle’s analysis, however, a revival of what Max Weber termed the Protestant ethic, principles that guided people to work for the future rather than immediate gratification, could be effective.  Neither author has much to say about how we are to decide what is “enough” for individuals and groups in a pluralistic society. Patel would no doubt be the more austere judge.

To Patel’s call for changed values, Coyle adds changes in measures of achievement and in our institutions of governance.  The ways we measure economic growth, productivity, and well-being are simply inadequate for dealing with our growing understanding of the importance of intangibles. With the revolution in information and communications technologies, services account for an ever larger share of production; we do a poor job of measuring  quality of services, and the shortcoming is especially severe regarding what we term quality of life matters.  The  technology revolution is also transforming how individuals, corporations, and political entities relate to one another. Coyle imagines that societal decision making can be shifted from centralized agencies to “involve a more productive  and thoughtful interplay between markets and governments than we’ve typically had in the past…”, but here I could not quite make out her image of that future. Perhaps she envisions social networking platforms supporting grass-roots participation, a sort of Swiss direct democracy via telethon or Facebook.

Development of such a participatory system would certainly signal the integration of a new set of technologies into our infrastructure.  In past decades, new infrastructure technologies have been accompanied by—and arguably enabled or perhaps caused—changes in how society operates. Rail and then highway transportation changed the patterns of human settlement; piped supply of clean water changed the way households operate.  These changes in turn have been accompanied by changes in our fundamental values, on the scale contemplated by Patel and Coyle.  If we are to have the change in values these authors argue we need for a sustainable future, then I believe we must expect to reshape our infrastructure.
