The idea of physical limits to
human economic systems is advanced by physical scientists and ecological
economists, as well as appealing to the common sense proposition that unending
growth in physical processes such as material extraction and waste disposal
will ultimately be inconsistent with any finite entity, even one as large as
the Earth. Yet growth remains the central aim of business and government almost
everywhere. This paper examines the history of the idea of economic growth and
the many influences and interests that supported — and still support — its
enshrinement as the principal aim of human societies. These include the
apparatus of propaganda in favour of corporate interests; the emphasis on
international trade; the funding of environmental denial; and, underlying all
these, the corporate requirement for profit to continue to increase. The
dominance of these influences has serious consequences for the natural world
and growth has failed to solve the problems of poverty.
Keywords: Limits to Growth; propaganda;
consumerism; environmental denial; planetary boundaries.
The
authors of The Limits to Growth (Meadows
et al., 1972) were not the first to draw attention to physical limits on the
expansion of the human economic system, but they enjoyed substantial attention,
especially in 1970s, and brought the concept into mainstream thinking. The
project came out of the concerns of the founding members of the Club of Rome
and drew on the discipline of systems analysis being developed at the
Massachusetts Institute of Technology (MIT).
The
Club of Rome, founded by Italian industrialist Aurelio Peccei and Scottish scientist
Alexander King, brought together a select group of prominent, mostly wealthy
individuals who wanted to address what they called the problematique,
translated as “the predicament of mankind”. Peccei saw post-war economic and
industrial advance as a double-edged sword and described himself as “perplexed
and worried by the orderless torrential character of this precipitous human
progress” (Barney, 1982, p.607). Soon after it was founded in 1968, the Club
commissioned the Limits to Growth project at MIT with researchers Donella
Meadows, Dennis Meadows, Jørgen Randers and William Behrens.
The
MIT team identified five major aspects of this predicament: accelerating
industrialisation, rapid population growth, extensive malnutrition, depletion
of non-renewable resources, and environmental decline. They formulated this
question: how could growing populations, locked into ever-expanding
industrialisation, avoid immense environmental degradation, exhaustion of the
resources on which everything depends, and the social chaos that would be
likely to follow decline or collapse? To answer this question, they devised
World3, a computer program that combined extensive data about the many
interacting aspects of the economy and the environment, with different scenarios
about changes that might be made. These scenarios ranged from business as usual
(the standard run), through several combinations that assumed extremely
advanced technology, to scenarios where both population and physical throughput
were stabilised. The standard run led to collapse around the middle of the
current century. Even massive technological advance could not avert this
outcome, but there were scenarios that could: those that stabilised population
and wound back the scale and rate of material extraction and waste.
The
book remains the best-selling environmental book ever published, but its
reception in the political and economic mainstream was mixed. In the early
years, both US President Carter and Prime Minister Trudeau of Canada took it
seriously and launched parallel studies (Barney et al., 1981; Barney, 1982;
Voyer and Murphy, 1984). From the beginning, however, most economists ridiculed
the idea that human economic systems have physical limits (Beckerman, 1972;
Economist, 1972; Nordhaus, 1973; Solow, 1973), an attitude which came to
prevail. One characterised the World3 computer program as “Garbage in, garbage
out”. Robert Gillette (1972), who reported for Science at the launch of the book, noted that
the “assumption of inevitable economic growth” constitutes “the very
foundation” of the economics profession—which may help to explain the intensity
of the assault from economists.
In
recent years, several researchers (Hall and Day, 2009; Turner, 2014) have
compared the Meadows projections with what has actually happened. The
correlation between the standard run (business as usual) and real world trends
over the intervening years is extremely close. Hall and Day (2009) could not
find “any model made by economists that is accurate over such a long time span”.
Given that the projections up to 2010 have proven accurate, it would seem wise
to question the pursuit of business as usual.
Unprecedented Growth since
1950
Growth,
of both economies and populations, was indeed “torrential” in the years after
the end of World War II, especially the first three decades. The world’s
population increased from just over 2.5 billion in 1950 to almost 4 billion in
1975.[1] In the same period, world GDP more than
doubled. Thus, by 1975, the base of both the economic system and human numbers
was already immense and doubling times were short. By the 1990s, annual
increase in world GDP has been estimated to approximate the entire global
output of 1900, about one trillion in 1990 US dollars (DeLong, 1998).[2]Although
economists like to argue that humans have been exploiting their resources and
pursuing economic growth since the Stone Age (Solow, 1974; Beckerman, 1972),
there has never been anything like the twentieth century.
Australian
climate scientist Will Steffen and colleagues have shown just how unusual it
was, in the sets of exponential graphs known as “The Great Acceleration”
(Steffen, Broadgate, et al., 2015). The graphs start at the year 1750 and run
to 2010; the disjunction around 1950 is clear in all of them. Figure 1 shows
the economic aspects of the growth boom. Despite the financial crisis of
2007-2008, the continuation of this trajectory is sought, to the maximum extent
possible, by governments and international organisations.

Acceleration, social and economic aspects, courtesy Will Steffen.
The
economists’ intense attack on Limits
to Growth reflects
the rift between the core assumptions of mainstream economics and those of the
physical sciences. Basic economics textbooks depict a standard model where the
circular flow between production and consumption has no natural context:
producers and consumers are seen to function without any reference to the
physical world of resources and wastes. Ecological economists, on the other
hand, and most physical scientists, accept Nature as the essential foundation
of the human economy; in this framework, production requires resource inputs from the
physical world and sinks where its wastes can be absorbed: depletion and
pollution are inescapable.
In
mainstream economics, economic growth is understood to be the result of two
factors: capital and labour. This picture was developed while energy and
resources were plentiful; economists could ignore the physical basis of
economic activity, including the role of energy. Physical scientists, on the
other hand, regard energy as the “master resource”, since no other commodity
can be produced without it (Cleveland, 1991; Zencey, 2013).[3]One
of the ecological economists, Kenneth Boulding, warned in 1966 that the
“cowboy” economy (which had commanded the limitless resources of an “empty
world”) was over; humanity faced a new situation which he called “spaceship
Earth”, a world that was rapidly filling up. Odd as it may seem, economics has
yet to fully acknowledge that energy is just as essential to production as are
labour and capital, even though the massive economic growth since 1950 has
depended on it.
Economic growth as a corporate
goal: inventing consumerism
Notions
of limits to economic growth threaten many powerful groups that depend on
continually rising profits and the expansion of the physical economy. One of
the crucial innovations of capitalism[4] was the system of accumulation, where
production surpluses are largely devoted to expansion of the enterprise. Growth
is indispensable to such a system, and the corporations that emerged around
1900 were determined to maintain it. The immense productive powers developed
over the nineteenth century had met the basic needs of most of the US
population by the early twentieth century and the captains of industry feared
that the system had triggered a permanent crisis of overproduction. The American
capitalist economy confronted the plenty it had created as a threat to its very
existence.
A
consumer solution, however, was simultaneously emerging. Edward Bernays[5]
(2005), one of the pioneers of the public
relations industry, pointed out in 1928 that mass production can only be
profitable if it ensures steady or increasing demand, which, he suggested,
could be accomplished “through advertising and propaganda”. Although the
practice of inciting consumption has earlier roots (Higgs, 2014, pp.68-69), the
first major surge of mass consumption was promoted in America in the 1920s. A
“new economic gospel of consumption” was urged (Cowdrick, 1927); new needs
could be created, with advertising enlisted to “augment and accelerate” the
process (Hunnicutt, 1996). People could be encouraged to give up thrift, value
goods over free time and, with ever-increasing aspirations, they would always be
chasing a receding goal. Just before the Wall Street Crash, President Herbert
Hoover’s Committee on Recent Economic Changes (1929) welcomed the “grand…
expansibility of human wants and desires”, celebrated an “almost insatiable
appetite for goods and services”, and foresaw “new wants that make way
endlessly for newer wants, as fast as they are satisfied”. People were
encouraged to board an escalator of desire (a stairway to heaven, perhaps) and
progressively ascend towards the luxuries of the affluent.
Although
the Great Depression interrupted this process, it resumed after World War II
with an intensity stimulated by corporate advertisers using debt facilities and
the new medium of television. As retail analyst, Victor Lebow, put it in 1955:
Our
enormously productive economy demands that we make consumption our way of life…
that we seek our spiritual satisfaction, our ego satisfaction, in consumption.
… We need things consumed, burned up, replaced and discarded at an ever
accelerating rate (Kettles, 2008, p.47).
Vance
Packard (1959) described the advertising men of this new era, putting “sizzle
into their messages by stirring up our status consciousness”, making what were
once luxuries into the “necessities of all classes”. Sold as status symbols
perhaps, it was endless material objects that were being consumed.
The
prospect of ever-extendable consumer desire, characterised as “progress”,
promised a new way forward for modern manufacture, a means to perpetuate
economic growth. Progress required the endless replacement of old needs with
new, old products with new. Notions of meeting everyone’s needs with an
adequate level of production did not feature. In this sense, the twentieth
century capitalist era unleashed desire with its complex individual peculiarities
and set it loose in the marketplace of material goods, supplanting basic
survival needs as the purpose and driver of economic growth. Up to now, there
has been little change in this strategy. As we run up against the limits of
material production, nothing could be more inimical to finding solutions.
Economic growth as policy goal:
the idea takes over
In
the reports of the IMF, World Bank, Organisation for Economic Co-operation and
Development (OECD) and G20, and in the speeches of our politicians, economic
growth is seen as imperative, and it may seem that government—and
international—economic policy has always embraced this view. However,
Australian economist H W Arndt (1978) demonstrated that the idea of economic
growth as a policy objective appeared quite abruptly in the 1950s—as did the
idea of “development”. Governments pursued neither material development nor
economic growth during the first half of the twentieth century, academic
economists rarely discussed it, and neither businessmen nor politicians thought
governments had any role in promoting it (Arndt, 1978).
At
his inauguration in 1949, President Harry Truman signalled a departure from
this position[6],
announcing the intention of the US to extend modern industrial production to
every corner of the earth: “More than half the people of the world are living
in conditions approaching misery…. Greater production is the key to prosperity
and peace…. [and will require] a wider and more vigorous application of modern
scientific and technical knowledge” (Truman 1949).
Soon
afterwards, a new field of economics emerged, defining the well-being of the
world’s people in terms of economic growth and the exploitation of resources.
The new “development economists” echoed Truman’s vision of technology as the
engine of human progress, and stressed capital accumulation as the central
facilitator. Energy did not play any role in their theories. Walt Rostow (1960)
held that “the age of high mass-consumption” is the ultimate stage of progress.
W Arthur Lewis (1954) argued that traditional cultures and subsistence
livelihoods must be swept away and replaced by the industrial money economy, a
necessary and inevitable process.
“We
are interested”, Lewis wrote, “not in the people in general, but only in the 10
per cent of them with the largest incomes…. The central fact of economic
development is that the distribution of incomes is altered in favour of the saving
class”. In this respect, the development economists adopted a “trickle down”
approach to solving the misery Truman lamented. Lewis focussed on consolidating
the wealth of the rich, who would instigate an economic “take-off”; at a later
stage, he believed, the resulting economic growth would reach the poor. In
recent times, neoliberal ideology embraced the same idea, with its claim that
cutting taxes for the wealthy leads them to invest and therefore benefit
everyone. Neither the expectations of the development economists nor the claims
of the neoliberals are supported by empirical evidence. In both cases, wealth
has “trickled up” (Higgs, 2014, pp.119-123).
Quest for the bigger pie
Several
imperatives underpinned the new scramble for economic growth in the post-war
world. After the Great Depression, full employment was regarded as an essential
policy objective and economic expansion was believed to be the only practical
way to achieve such a goal. In the “developing” world too, where national
liberation movements had to be accommodated or neutralised, growth was
preferred to redistribution of land or resources. Although growth has increased
the numbers of the middle class in some developing countries, especially China,
and despite persistent claims that economic growth has “lifted millions out of
poverty”, the reality is not so rosy. More than half the world’s people still
live in poverty, without reliable material security, even if the definitions
used by the rich world’s institutions tend to obscure the fact. Prosperity is
concentrated among a privileged minority (Higgs, 2014, pp.105-162; Hickel,
2017).
The
so-called “bigger pie” was promoted as the obvious solution to all social
problems—debt, unemployment, poverty, and even the environmental damage involved
in baking it. It still remains the primary strategy for the institutions of the
OECD world, whether businesses, national governments, or the international
bodies allied to business. In these forums, no-one asks where we are to find
the ever less accessible ingredients for this ever more gargantuan pie.
Post-war
theories of economic growth harboured two key assumptions—and continue to do
so. Firstly, economic growth is regarded as an inevitable stage of human
civilisation, a natural and linear progression from more “primitive” social
forms. Secondly, economic growth is seen as a process of indefinite duration,
with no limits in space or time. On a graph, it is a curve which continues
upward forever, permanently exponential. Such beliefs are a form of magical
thinking. They ignore problems of resource scarcity, especially that of energy,
they ignore waste and they ignore the destruction of the natural world in which
everything is based.
Arndt’s
fears that the limits critique would end the pursuit of economic growth were
groundless; in fact, the influence of such ideas waned as neoliberalism
increasingly monopolised the economic discourse, and began to dominate
government policy from around 1980 when Ronald Reagan was elected as US
President, and Margaret Thatcher had just settled into Downing Street.
Naturalising the “free market”
Neither
natural nor inevitable, the so-called free market has received massive advocacy
for more than a century—in order to create, retain and extend public
acceptance. The roots of this process lie back in the early decades of the
twentieth century, just as the modern corporation was emerging (Higgs, 2014,
pp.167-169). By the 1920s, with Edward Bernays in the lead, public relations
(PR) began to gain ground as a career path. As Bernays (2005, pp.37-38)
explained in 1928, with a candour rarely heard these days:
The
conscious and intelligent manipulation of the organised habits and opinions of
the masses is an important element in democratic society. Those who manipulate
this unseen mechanism of society constitute an invisible government which is
the true ruling power of our country. … It is they who pull the wires which
control the public mind.
Bernays
described himself as a “propaganda specialist” or a “public relations counsel”.
He and his colleagues were anxious to offer their services to corporations and were
instrumental in founding an entire industry that has since operated along these
lines, selling not only commodities but also opinions on a great range of
social, political, economic, and environmental issues.
One
early PR man, Ivy Lee, simply made up facts to suit the purpose (Higgs, 2014,
p.170), a precursor of the “alternative facts” which have become more palpable
than ever since 2016. Later, with the advent of Bernays, PR centred on the
careful construction of image: for example the idea that corporations exist to
serve, rather than turn a profit; the displacement of the term “big business”
with a new enemy, Big Government; the denigration of public servants and
politicians as “fat cats” while CEOs were depicted as models of generosity; and
the replacement of terms like capitalism, laissez faire and private enterprise
with the sanitised expression “free enterprise” (Higgs, 2014, pp.175-178).
The
work of hired propaganda specialists was augmented by that of think tanks later
in the twentieth century. Just a handful of these institutions predate 1970;
but by 2015, their number was estimated at almost 7,000 (McGann, 2017). Funded
by corporations that prefer to avoid regulation (for example tobacco, asbestos,
chemicals, fossil fuels, mining, car manufacturers), business-friendly
activists set out to “litter the world” with “free enterprise” think tanks
(Cockett, 1995, p.307). In the US, the family foundations where fortunes of
corporate leaders are often held also chipped in handsomely (Higgs, 2014, p.90,
pp.191-192).
These
ferociously proliferating think tanks have disseminated industry propaganda as
“independent research” ever since. Most are tax-exempt and vociferous claims to
independence disguise their political ties. One think tank operative, however,
told researcher Georgina Murray (2006) that it would be naive to imagine that
think tanks are established “by Santa Claus or the tooth fairy”. Rather, as
Irving Kristol (1977) admitted, they are always intended to “shape or reshape
the climate of public opinion”. Think tank staff enjoy immense influence in the
media of the English-speaking world, where they are depicted as scholars on a
equal footing with peer-reviewed academics and have also been recruited into governments.
Heritage, American Enterprise Institute and Hoover supplied 150 of Reagan’s
staff—and numerous Heritage operatives were “borrowed” by George W Bush. In the
UK, the Thatcher government owed much to the Institute of Economic Affairs and
the Centre for Policy Studies (Higgs 2014, pp.96-98, 214-215).
Think
tanks promoted the bogus standard of “balance” in place of impartiality and
accuracy, as they pursued “equal time” in media and educational institutions.
Analysis of the US prestige press between 1988 and 2002, showed that “balanced”
reporting successfully obscured the scientific consensus on global warming by
giving equal, or even greater, space to those who denied that climate change
was occurring (Boykoff and Boykoff, 2004). This trend is symptomatic of
multiple efforts to undermine any science that threatens polluting industries
(Higgs, 2014, pp.211-238) and demonstrates the efficacy of “balance” as a tool
of obfuscation.
The drive for “free trade”
By
the early 1980s, neoliberal ideology was established as the economic creed of
the governments of the UK, US and Australia and had begun to penetrate
international institutions. When assisting developing countries, the IMF now
insisted on Structural Adjustment Programs which required strict market policies
in exchange for its help. These programs were rarely in the interests of the
citizens of these countries: privatisation, deregulation, balanced budgets,
abolition of welfare measures and removing barriers to foreign investment
usually disadvantaged the poor.
By
1986, the General Agreement on Tariffs and Trade (GATT), founded in 1948, had
attracted 108 member countries and slashed tariffs by 75 per cent. Like “free
enterprise”, free trade is not so much about freedom, but about abolishing
rules for corporations and substituting rules for governments and citizens.
Already, under the GATT arrangements, rules relating to environment, health or
working conditions were excluded as not “trade-related”. The World Trade
Organisation, fiercely pursued by corporate lobbyists, was finally established
in 1995, and followed the same blueprint. Dispute panels of both entities were
run by corporate lawyers or economists with no input from environmental
experts.
Under
the trade regime of the GATT-WTO system, trade has priority over environmental,
health, and social justice considerations, regardless of the wishes of a
government and the people it represents. To enforce trade obligations, the
rules penalise countries if they choose to assess risk and protect citizens or
environment under their own standards. For example, it is regarded as
irrelevant if fish are caught with collateral slaughter of dolphins, or if
residues of pesticide or growth promoting hormones exceed local limits. The
burden of proof is reversed, so that citizens must prove commodities are unsafe
rather than manufacturers having to show they are safe.
Although
the GATT concentrated on removing tariffs on actual goods, the WTO and
subsequent multi-party agreements such as the North American Free Trade
Agreement, moved to abolish restrictions on capital flows, making it nearly
impossible to prevent stampedes of capital in and out of countries on
speculative errands. Overall, economic goals gained precedence over all other
priorities. By the new century, business priorities were entrenched in public
discourse, government policy, and international institutions (Higgs, 2014,
pp.246-254). Economic growth was established almost everywhere as the only way
to solve any problem. Environmental protection and social justice, both
national and worldwide, were now deemed to depend on it.
Approaching the planetary
boundaries: four major problems
Over
the twentieth century, physical production increased twenty-fold and human
population quadrupled. The consequences continue to cascade through the natural
and human world, literally liquidating life on earth. Although the roots of
this post-war growth lie deep in our history, it was not until about 1950 that
the scale of the human project began to outgrow planet Earth decisively. It
might not have mattered so very greatly at other points in history, but frantic
attempts to restart the growth curve of the past 70 years and to enshrine
economic growth as the central element in government policy are now in conflict
with physical reality.
Figure
1 showed the economic aspects of the growth boom. Figure 2 shows the
corresponding
physical changes in the natural world. From the 1960s onwards, scientists such
as Rachel Carson sounded alarm about various problems associated with growth,
but this was not the case in governments, bureaucracies and public debate,
where economic growth was gradually being entrenched as the central objective
of collective human effort. The transition to service economies in developed
countries has not moderated the global trajectory of either economic or natural
impacts, since our consumption continues to increase, with even greater
quantities of far cheaper material objects imported from the countries that now
conduct manufacture.

The
concept of planetary boundaries has been developed by a team led by Johan
Rockström of the Stockholm Resilience Centre and Will Steffen from the
Australian National University. It is a work in progress and the exact extent
to which we are breaching these boundaries is still being quantified; the
team’s most recent paper (Steffen, Richardson, et al., 2015) argued that two
problems are already extremely dangerous and two others are well on the way.
Biodiversity
The
boundaries team argues that the most serious problem is loss of biodiversity.[7]
We are losing species 100 to 1,000 times
faster than the background rate through geological time and the world lost
something like 50 per cent of all its mammals, birds, fish, amphibians and
reptiles in the forty years following 1970. This research refers to numbers of
animals, not species, but smaller populations are increasingly vulnerable
(Ceballos et al., 2015; WWF, 2014).
Trade
plays a crucial role in obscuring the location of the ecological damage
embodied in consumer products. It allows the people who consume most of the
goods to transfer the damage involved to the generally much poorer people who
host the extraction of the materials they are made from and the factories where
they are made. Manfred Lenzen and his team (2012) estimated that some 30 per
cent of extinctions are related to trade. The website shipmap.org gives a
graphic picture of the immense scale of trade by sea; trade by air is also
extensive. My own country, Australia, occupies an unusual position for a
developed country. Mainly through agriculture—and to some extent mining—we
sustain more ecological damage on behalf of others than we export through
consuming products made elsewhere. Consumption in the US, Japan and Europe,
however, transfers significant ecological damage, especially to countries in
Africa and South-East Asia.
Disruption of biogeochemical
cycles
For
Steffen and colleagues the second most immediate danger lies in the impact of
fertilisers: the nitrogen and phosphorous cycles are radically disrupted. In
Nature, most nitrogen was inert in our atmosphere (though mobilised by bacteria
and leguminous plants). Mainly through making fertiliser, nitrogen is now
flooding through our rivers, groundwater and continental shelves, causing algal
blooms and dead zones where fish, molluscs and aquatic insects may die,
sometimes in large numbers.[8]
In the case of the other widely dispersed
fertiliser, phosphorous, there is an added danger—phosphate rock is a resource
in decline, with grim implications for agriculture (Cordell, 2017). Phosphorous
is an element, one of the indispensable building blocks of DNA, and no market
on earth will be able to manifest a substitute, though it could be recovered
from human waste.
Land use changes
Land
use change is in the “amber zone”, close to crossing the boundary into extreme
danger; it is also implicated in the threat to biodiversity. Humans are still
clearing millions of hectares of vegetation every year and draining wetlands.
Tropical forests of Asia and Africa are being replaced by palm oil plantations,
also expanding in Latin America, where clearing already provides cattle
pasture, soybean and sugar cane. Oil palm plantations involve the death of
immense numbers of individual animals and the annihilation of vast tracts of
tropical forest. In China and South Korea, wetlands that support migrating
birds are being drained and transformed into ports. Growing populations, in
both rich and poor countries, contribute to this pressure (Crist, Mora and
Engelman, 2017).
Global warming
Also
in the amber zone is global warming. We are well on the way to a very hot
planet and, to remain below the 2°C target, we require technologies which do
not yet exist for extracting carbon from the atmosphere. Even if the
commitments made in Paris are all honoured, it will already be 2°C hotter than
pre-industrial times[9]
by 2050 and at least 2.7°C hotter by
2100. The aspirational 1.5°C target is likely to be reached by the early 2030s
(Watson et al., 2016).
This
situation is better than the likelihood of 4°C which applied before Paris, but
there is no guarantee that we will limit the damage to 2.7°C. Even if we do,
that temperature will reduce crop yields, make many places unliveable, melt the
glaciers that supply water to billions in Asia and South America, destroy coral
reefs and many other species, and produce significant—even catastrophic—sea
level rise. James Hansen and his team (2015) regard 2°C as already posing a
dangerous sea level threat, as much as 3m this century. The Greenland icesheet
is melting at an accelerating rate. Not considered likely a decade ago, the
entire coast of West Antarctica is dotted with ice shelves that are shrinking
or collapsing as warm seawater intrudes underneath. Glaciers are speeding up as
a result; Pine Island glacier is considered to be melting irreversibly, as is
Thwaites and other adjacent glaciers (Rignot et al., 2014). It is expected to
take several centuries before really catastrophic sea level rise occurs, but
Hansen et al. (2016), as well as many glaciologists, warn that the melting of
the polar icesheets involves non-linear processes of disintegration, so the
timing is unknown and may be far quicker than assumed.
Pollution
Alongside
these four major crises (species loss; disruption of the biogeochemical cycles;
land clearing; and global warming), Steffen’s team is also aiming to quantify
how close we are to being overwhelmed by pollution and novel substances. This
aspect of their project is ongoing, but we do know that there are more than 5
trillion plastic fragments in the ocean, so prevalent that 90 per cent of sea
birds are now ingesting them, while deep sea creatures are eating micro-plastic
fibres disgorged by our washing machines (Eriksen et al., 2015; Taylor et al.,
2016). And we do know that the ocean is acidifying.
Conclusion
As
the historian Dipesh Chakrabarty (2009) noted, what is new about the pursuit of
the study of history in the twenty-first century is the need to address the
intersection between natural history and human history. The key to this
collision is the concept of scale, an insight brought to prominence by the
ecological economists. Herman Daly and his colleagues perceived that the scale
of the human project in relation to the scale of the planet had reached an
unsustainable ratio. Especially since World War II, the human project has
altered—and continues to alter—the actual physical condition of the earth.
While
deniers of ecological crisis like to argue that notions of human impacts on the
geophysical scale are laughable, this attitude reveals an ignorance of natural
history. It is scientifically uncontested that humble cyanobacteria
microscopically producing oxygen over two or three eons created an oxygen-rich
atmosphere suitable for complex life, including ours. If algae can have
planetary impacts—expressed very slowly, but unquestionably a geophysical
force—big animals such as humans are obviously in a position to change the
planet rather faster.
Herman
Daly’s ten-point program (2008) is an excellent example of the sweeping changes
ecological economists consider necessary, most of them totally unacceptable to
corporate capitalism. His policy summary includes ecological tax reform;
limitations on unequal income distribution; the re-regulation of international
commerce; the downgrading of the IMF, World Bank, and WTO; the abolition of
fractional reserve banking; stabilisation of the population; and the transfer
of the remaining commons to public trust. Under the current economic system,
there seems little to no chance that any of these measures would be adopted by
governments that exist at the pleasure of market forces.
And
yet, structural change is indispensable. Some propose a transition to
socialism, others hope to tame the capitalist economy and establish a steady
state economy. Both options seem equally hard to imagine in the neoliberal era.
However, to hijack Margaret Thatcher’s famous expression, “there is no alternative”.
We
need a different kind of economy, one designed to meet needs rather than create
them; we need to abandon the consumer path to human advancement and the
reduction of our choices to monetary terms. The consumer template for the human
future has outworn its usefulness. Stimulating consumption in the interests of
growth and chasing economies of scale was, perhaps, suitable for the “empty
world”. In the “full world” (and getting fuller) we need redistributive justice
within and between countries and a plan for the rich world to reduce its
material demands to allow space for the rest of the world to reach material
security.

DeLong uses several methods. Estimated annual additions for the 1990s vary from
half the entire economy of 1900 to the entire 1900 economy.
[3]. By
the 1950s, empirical studies had shown that capital and labour could explain
only one seventh of observed economic growth in the US. There was no clear
candidate for the rather large missing ingredient, although “technical
progress” was often assumed to provide the best explanation (Ayres and Ayres,
2009, p.11). Later, Robert Ayres (a physicist) and Benjamin Warr identified the
missing factor as energy—or, more exactly, as the increasing efficiency with
which energy and raw materials are converted into useful work. In this
explanation, technological improvement plays a part, but Ayres and Ayres (2009,
pp.9-18) stress that: “labour and capital extract energy;
they don’t make it”. Thus energy is a prerequisite for,
not a product of economic activity.

With the partial exception of Cuba, socialist and communist economies have been
just as dedicated to industrialisation and economic growth as their capitalist
rivals. Eastern Europe and the former Soviet Union were even more severely
polluted than the West, as is China today; although a state-controlled economy,
China is hardly “socialist” (Higgs, 2014, pp.5-7, 11-13).

Most serious in the sense of most well advanced. Many scientists argue that
non-human species and ecosystems have intrinsic value, a view I share; but even
if one rejects this view, humans nonetheless depend on the fabric of life on
earth for survival—for food, clean water, pollination and numerous other
ecosystem services as well as for novel substances, including drugs (see Crist,
Mora and Engelman, 2017).

Humans now produce more reactive nitrogen than natural processes do. Excess
nitrogen involves hazards in addition to eutrophication: the greenhouse gas
nitrous oxide (N2O) is released during fertiliser application;
nitrate may also leach into groundwater and contaminate drinking supplies.
