Anyone who believes exponential growth can go on forever in a finite world, is either a madman or an economist.
~Kenneth Boulding, Economics professor
Q: Does a growing economy require a growing population?
Many Free Market economists say that business needs a growing population
to be successful. But in reality, money buys things, not people.
For example: if you want to do well selling shoes, one Imelda Marcos is
better than a whole town in rural anywhere. The number of feet to wear the
shoes is irrelevant if they have no money to buy them.
Business doesn't need more people to prosper, business needs people to
prosper more.
Our current economic system only seems to be dependent on an
ever-increasing population. Actually, with increased density, some people
benefit while others suffer. All non-human life suffers from human increase,
but economic systems ignore that cost since it doesn't have a price tag. So,
let's look at economics only as it affects the humans it's meant to serve.
A large, expendable work force benefits owners, but it places labor at a
disadvantage. Workers with dependents can't afford to hold out on strike, or
take chances on being permanently replaced. High unemployment reduces wages,
while high demand for workers increases wages and benefits.
New housing provides jobs for construction workers and gains investors more
capital for further development. However, much of the cost of increasing
human habitat is borne by those who already live in the area: their taxes
must increase to subsidize population growth. With a shift in priorities,
maintaining and improving existing buildings could provide as many jobs as
new construction provides.
Landlords fare better when population increases because higher demand for
rental units equals higher rent payments. Tenants benefit from a shrinking
population as housing becomes more affordable.
Real estate speculators make money from rising property values, which are
driven by demand for that property. Homeowners who wish to stay where they
are must pay more in taxes when their homes are worth more on the market.
Businesses which focus on the needs of infants and young people will have
fewer customers as birth rates improve, however, fewer customers doesn't
automatically mean less income. Many potential consumers can't afford the
products offered, and with smaller families, just as much money could be
spent on children's products. Often, companies also cater to other age
groups, and money not spent on children's needs is available for those
products and services.
Education may seem dependent on an increasing, or at least a steady flow of
new students. However, providing adequate education over-taxes local
economies, and many citizens resist paying. With fewer students, class sizes
could improve, and capital expenditures for new schools would shrink.
Existing schools could get their needed repairs and improvements. As with
diversification in other businesses, public schools could cater to wider age
groups and increase their customer base.
Chain letters involving money, and pyramid financial
arrangements such as Ponzi schemes, are illegal, since they benefit the
first to get involved and collapse when there are no longer enough new people
paying in. Outlawed in the private sector, many government retirement systems
unsustainably depend on increasing numbers of wage earners to pay
entitlements. Systems dependent on growth eventually fail, as pyramid scams
and empires always have.
When our population density begins to improve, and sensible adjustments are
made, economic systems as a whole will become more sustainable and
potentially more just.

The new demographics that are causing populations to age and to shrink are something to celebrate. Humanity was once caught in the trap of high fertility and high mortality. Now it has escaped into the freedom of low fertility and low mortality. Women's control over the number of children they have is an unqualified good -- as is the average person's enjoyment, in rich countries, of ten more years of life than they had in 1960. Politicians may fear the decline of their nations' economic prowess, but people should celebrate the new demographics as heralding a golden age.
~Editorial from The Economist January 7, 2006
Despite the wisdom of the above quote, it is a rare expression of lower
birth rates' positive side. Those who benefit most from an increasing
population density -- identified in the previous Q & A -- also happen to
own or finance major media outlets. As a result, we are regularly told that
an economic crisis looms if we don't breed more future workers. A Washington
Post reporter wrote of countries struggling with the threat of zero
population growth.
Although most systems of providing for retired citizens are financed by
taxing working citizens, the concept of needing younger people to support
older people is obsolete. If used responsibly, products from the industrial
and technological revolutions could satisfy our needs without selling our
children into wage slavery.
Social security systems are artificial, so adjustments for changes, such
as a reduction in the number of potential workers, can be made.
Automation removes more workers from payrolls than birth control does. Owners
of the machines gain the wages formerly paid to workers, without
paying a percentage into pension funds. Adjustments could be made.
Unemployment reveals that we already have enough potential workers.
Increasing employment and increasing wages will increase funds paid to social
security.
In the USA, a pea-and-shell game is being played on taxpayers. More money is
taken in for social security than is shelled out, but the remainder vanishes
instead of being invested for future pensioners. The solution to having our
nest eggs stolen isn't to lay more eggs.

Each new human we don't create is the equivalent of around 72 years of 100% recycling. We save over 50 years of car driving, avoid tons of pollution, and prevent the potential for an additional procreation 20 years later.
When the impact our descendants' descendants have on Earth's biosphere is added to what we are saving, it becomes astronomical. And, if we decide to not make two more of us, we save astronomical doubled.
Volunteers who are ready to make even more of a commitment might consider not producing 10 new people: 720 human-years of industrial consumption and pollution can be saved by just one pair of us. Congratulations!
All kidding aside, and that's a good place to put "kidding," running out of resources mostly concerns humanity, not the ecosphere. Conservation usually means "use it up more slowly." One conservation organization's motto: "Conserving natural resources for our future." Resource extraction disrupts ecosystems, so when a resource is all gone, life might start to recover there.
Many believe that Earth could supply an endless amount of resources. "The Economist" magazine for example: "The notion of a growing number of people fighting over a fixed resource pie is Malthusian bosh . . . "
Cornucopian pie-in-the-sky might look tastier, but bosh is all we'll be able to sink our teeth into on a finite Earth.
Although humanity has reason to fret over material and energy shortages,
loss of wildlife habitat diminishes life far more, and we don't even count
it. It's not a resource if we can't use it. Unlike copper, which the late Julian Simon
assured us could be made out of something else if we run out, wilderness
areas are definitely finite.
If we cut our per capita consumption in half and double our numbers, we'll
be right back where we started.

There are two main aspects to over-population: the ecological and the human.
In countries with high birth rates and recurring famine, the impact on humans is greatest. In countries with lower birth rates and high consumption, the environmental impact is greatest. We need to work in both of these areas to relieve human suffering and ecological degradation.
At present, a human born in the wealthy part of the world has a much greater environmental impact than one born in a poor country. However, activities of poor agrarian peoples also have an impact on the environment.
Gathering firewood and grazing at the edges of deserts causes the deserts to expand. Hungry people are kept out of game preserves in Africa by shooting trespassers. As the number of hungry people grows, this gruesome task will become more difficult. If a government is overthrown and the game wardens temporarily removed, many major species could be hunted to extinction in a short time.
Pollution from a crowded city in a non-industrialized country is shorter-lived than from our industrialized cities. Chernobyl will be radioactive for 24,000 years, while organic pollution will flush out of a river in a few years.
So-called developing countries are gaining on industrialized nations in their consumption of fossil fuels and production of toxic wastes. Much of this industry is being imported from industrialized areas to take advantage of cheaper labor. Cheaper labor is another result of high birth rates.
Whether we're living abundant lives or are starving, our lives and the planet's health will be most improved by refraining from reproduction.

Q: Isn't unequal distribution of wealth the cause of hunger rather than over-population?

Compelling evidence supports this contention. A small percent of the world's population is using most of the energy and resources. Equal distribution, if possible, would likely end hunger for a while.
Setting aside for a moment the fact that people who aren't created won't starve, the single greatest cause of hunger today is economic exploitation. Instead of growing food, exploited regions must raise cash crops to pay the interest on national debts. Profit from natural resource extraction could provide for people's needs if it weren't for people's greeds.
More conservation by us consumption-addicts is only fair, but the lion's share of Earth's plunder goes to a fraction of one percent of humanity. Brute force sustains this ancient world order, same as it ever has.
Phasing out the human race won't automatically bring about economic justice, but it will make it possible. The smaller our human family, the easier feeding everyone at the dinner table will be.
From an Earth-centered view, we're pluckin' a mighty skinny chicken here,
and it doesn't matter to the chicken who gets the drumstick and who gets the
neck.
Although everyone on Earth could theoretically be fed, the fact remains
that they simply are not. Billions of people are not getting enough to eat,
and many are starving to death. Efforts to eliminate hunger are quickly
consumed by ever more members of our human family.
For the famous photo of a Sudanese child crawling toward a feeding station
while a well-fed vulture follows in case she doesn't make it: "Not recommended viewing by those already suffering from
depression over the human condition."
Q. Wealthy countries have low fertility rates, so why not just increase a nation's Gross Domestic Product and let birth rates fall naturally?

The correlation between TFR and GDP shown above is often presented as
evidence that poverty causes high birth rates. It could just as easily show
that high birth rates cause poverty. Are people breeding more because they
are poor, or are they poor because they breed more? Many countries have low
birth rates and low per capita income, so other factors are likely
involved.
Where there's a cultural preference for large families, subjugation of women,
and a lack of reproductive freedom, economics is likely to have less
influence on TFR.
The Demographic
Transition Model suggests that birth rates fall when "undeveloped"
countries industrialize and become "developed". However, cross-cultural
generalizations rarely hold up to analysis. Improved living standards
theoretically cause couples to want smaller families, but in reality, when
couples perceive a better future they're likely to have more children and to
have them sooner. The reverse also holds true: US birth rates fell to a
historical low during the Great Depression of the 1930s, and rebounded with a
Baby Boom during post war economic optimism.

Only after the last tree has been cut down,
Only after the last fish has been caught,
Only after the last river has been poisoned,
Only then will you realize that money cannot be eaten. ~ Cree Indian Prophecy

Slash-and-burn was sustainable for thousands of years in sparsely populated regions. When a people returned to an area that had been slashed and burned, the resources had recovered enough to do it again. We're still slashing and burning, but now there's no recovery time due to our increased numbers and subsequently shorter cycles.
Most modern industrial economies are dependent on large expendable labor pools, availability of raw materials, scarcity of goods, and unlimited wants.
A sustainable economic system is based on the reality of limits to growth and a concern for long-term effects. Rather than using up resources and throwing away the waste, a sustainable system conserves and reuses.
To keep the resource-exploitation machinery running, we are sacrificing the planet's true wealth: life itself. This insatiable monster seems bent on consuming all life on Earth, and we are working overtime to keep it fed. It feeds mainly on our offspring. We should let it starve.
