The Climax of Humanity
By George Musser
September 2005 Issue
Demographically and economically, our era is unique in human
history. Depending on how we manage the next few decades, we could usher in
environmental sustainability - or collapse.
The 21st century feels like a letdown. We were promised flying cars,
space colonies and 15-hour workweeks. Robots were supposed to do our chores,
except when they were organizing rebellions; children were supposed to learn
about disease from history books; portable fusion reactors were supposed to
be on sale at the Home Depot. Even dystopian visions of the future predicted
leaps of technology and social organization that leave our era in the dust.
Looking beyond the blinking lights and whirring gizmos, though, the new
century is shaping up as one of the most amazing periods in human history.
Three great transitions set in motion by the Industrial Revolution are
reaching their culmination. After several centuries of
faster-than-exponential growth, the world's population is stabilizing.
Judging from current trends, it will plateau at around nine billion people
toward the middle of this century. Meanwhile extreme poverty is receding
both as a percentage of population and in absolute numbers. If China and
India continue to follow in the economic footsteps of Japan and South Korea,
by 2050 the average Chinese will be as rich as the average Swiss is today;
the average Indian, as rich as today's Israeli. As humanity grows in size
and wealth, however, it increasingly presses against the limits of the
planet. Already we pump out carbon dioxide three times as fast as the oceans
and land can absorb it; midcentury is when climatologists think global
warming will really begin to bite. At the rate things are going, the world's
forests and fisheries will be exhausted even sooner.
These three concurrent, intertwined transitions - demographic, economic,
environmental - are what historians of the future will remember when they
look back on our age. They are transforming everything from geopolitics to
the structure of families. And they pose problems on a scale that humans
have little experience with. As Harvard University biologist E.O. Wilson
puts it, we are about to pass through "the bottleneck," a period of maximum
stress on natural resources and human ingenuity.
The trends are evident in everyday life. Many of us have had the
experience of getting lost in our hometowns because they have grown so much.
But growth is slowing as families shrink. Ever more children grow up not
just without siblings but also without aunts, uncles or cousins. (Some
people find that sad, but the only other way to have a stable population is
for death rates to rise.) Chinese goods line Wal-Mart shelves, Indians
handle customer-service calls, and, in turn, ever more Asians buy Western
products. Spring flowers bloom a week earlier than they did 50 years ago
because of global warming, and restaurants serve different types of fish
than they used to because species that were once common have been fished
Looking at the present era in historical context helps to put the
world's myriad problems in perspective. Many of those problems stem,
directly or indirectly, from growth. As growth tapers off, humanity will
have a chance to close the books on them. A bottleneck may be tough to
squeeze through, but once you do, the worst is behind you.
The transitions we are undergoing define the scope of the challenges.
Scientists can estimate, at least roughly, how many people will inhabit
Earth, what they are going to need and want, what resources are available,
and when it is all going to happen. By the latter half of this century,
humanity could enter an equilibrium in which economic growth, currently
driven by the combination of more productivity, more people and more
resources, will flow entirely from productivity - which would take much of
the edge off conflicts between the economy and the environment. Old
challenges will give way to new ones. This process is already evident in
countries at the leading edge of the transitions. The Social Security debate
in the U.S., like worries about pensions in Europe and Japan, is the sound
of a society planning for life after growth.
In the public's eyes, demographers have a checkered reputation. Thirty
years ago, wasn't overpopulation the big concern? Paul Ehrlich's book The
Population Bomb was a best seller. The film Soylent Green, starring Charlton
Heston, dramatized a future in which people would be stacked like cordwood
and fed little squares that looked like tofu but weren't. Lately, though,
underpopulation has become the cause célèbre, heralded by neoconservatives
such as Nicholas Eberstadt. Their concern is epitomized by another Heston
movie: The Omega Man, in which humanity dwindles to nothingness. So which
will it be: Too many people or too few?
Mainstream demographers have not swung back and forth nearly as much as
these extreme depictions might suggest. Families in the developing world
have shrunk faster than expected, but the forecasts described in Scientific
American's 1974 special issue on population have largely stood the test of
time. In fact, the Soylent Green and Omega Man scenarios each contain an
element of truth. Humanity is still growing enormously in absolute terms,
and past success at avoiding Malthusian nightmares is no guarantee of future
performance. The decline in growth rates is a worry, though. Historically,
most stable or shrinking societies have been down at heel.
Partisans of one scenario shrug off the challenges of the other,
expressing "confidence" that they can be handled without actually doing much
to ensure that they are. Once you blow away the fog of ideology, the
outlines of a comprehensive action plan begin to emerge. It is hardly the
only way forward, but it can serve as a starting point for discussion.
A recurring theme of this plan is that business is not necessarily the
enemy of nature, or vice versa. Traditionally the economy and environment
have not even been described in like terms. The most-watched economic
statistics, such as gross domestic product (GDP), do not measure resource
depletion; they are essentially measures of cash flow rather than balance
sheets of assets and liabilities. If you clear-cut a forest, GDP jumps even
though you have wiped out an asset that could have brought in a steady
stream of income.
More broadly, the prices we pay for goods and services seldom include
the associated environmental costs. Someone else picks up the tab - and that
someone is usually us, in another guise. By one estimate, the average
American taxpayer forks out $2,000 a year to subsidize farming, driving,
mining and other activities with a heavy environmental footprint. The
distorted market gives consumers and producers little incentive to clean up.
Environmentalists inadvertently reinforce this tendency when they focus on
the priceless attractions of nature, which are deeply meaningful but
difficult to weigh against more pressing concerns. The Endangered Species
Act has provided iconic examples of advocates talking past one another.
Greens blamed the plight of spotted owls on loggers; the loggers blamed
unemployment on self-indulgent ornithology. In fact, both were victims of
In recent years, economists and environmental scientists have come
together to hang a price tag on nature's benefits. Far from demeaning
nature, this exercise reveals how much we depend on it. The Millennium
Ecosystem Assessment, published earlier this year, identified services -
from pollination to water filtration - that humans would have to provide for
themselves, at great cost, if nature did not. Of the 24 broad categories of
services, the team found that 15 are being used faster than they regenerate.
When the environment is properly accounted for, what is good for nature
is often what is good for the economy and even for individual business
sectors. Fishers, for example, maximize their profits when they harvest
fisheries at a sustainable level; beyond that point, both yields and profits
decline as more people chase ever fewer fish. To be sure, life is not always
so convenient. Society must sometimes make real trade-offs. But it is only
beginning to explore the win-win options.
If decision makers can get the framework right, the future of humanity
will be secured by thousands of mundane decisions: how many babies people
have, where they graze their cattle, how they insulate their houses. It is
usually in mundane matters that the most profound advances are made. What
makes a community rich is not the computers and the DVDs, which you can find
nowadays even in humble villages. It is the sewage pipes, the soft beds, the
sense of physical and economic security. By helping to bring these benefits
of modernity to all, science and technology will have done something more
spectacular than building space colonies.
