Is Overpopulation a Legitimate Threat to Humanity
and the Planet?
A recent Retro Report examines how the
apocalyptic predictions
about overpopulation made by the
biologist Paul Ehrlich, in his 1968 book “The Population Bomb,” have not
come to
pass. Disease-resistant crops,
improved health standards and a broader demographic shift from an
agricultural society have kept the problem at bay.
But do we still need to worry about overcrowding? Is the threat of
overpopulation overblown?

1. Overconsumption Is a Grave
Threat
We have to radically change how we produce what we
consume. But we've done it before.
2. It’s
Not a Numbers Problem
Resources are distributed so
inequitably, and used so wastefully, that it is virtually impossible to know how
many people the planet can sustain.
3. Asia
Must Build a Less Wasteful Economy
The simple fact is that
five to six billion people from Asia cannot and should not aspire to lifestyles
that are currently taken for granted in the West.
4. Empower Women for the Planet’s Health
Providing family planning for those who want it could
provide up to 29 percent of needed reductions in carbon
emissions.
5. The Violent Side Effect to High
Fertility Rates
Regions with very large youth cohorts are
historically far more prone to violence than older
populations.
6. Ehrlich Was
Right
Expanding human populations cannot be sustained on an
Earth with finite carrying capacity.

It’s Not a Numbers
Problem
Give our species some credit: We’ve learned a lot
in the half-century since Paul Ehrlich warned that overpopulation would spell
our doom.
Start with the term "overpopulation." It implies that there are
too many people in relation to the planet’s resources, a concept that has fallen
out of favor. We now know that resources are distributed so inequitably, and
used so wastefully, that it is virtually impossible to determine how many people
the planet can sustain.
We’ve also learned that it’s absurd to attribute
any environmental problem to human numbers alone. Americans, for example,
comprise about 4 percent of the world’s population, but produce over 17 percent
of climate-changing carbon emissions. So, for the global climate, consumption in
the U.S. is a much bigger problem than, say, population growth in
Niger.
Does that mean that human numbers are irrelevant to environmental
sustainability? Not exactly. Current inequities are not — and must not be — set
for all time. Yet the planet could not support today’s 7 billion people living
as Americans now do, much less a future world population of up to 11 billion.
In a sustainable, just world, Americans would consume a smaller share of
the globe's resources, while those in what is now the developing world would
consume more. To remain within planetary limits, we would all produce and
consume differently. Those goals might be easier to achieve if we came in at the
low end of the United Nations' population projections — with about eight billion
human beings by 2050, rather than nearly 11 billion.
Does that require a
new regime of coercive "population control"? Absolutely not. Because the most
important lesson we’ve learned about population is this: Women’s rights are key.
Where women have the means and the power to make their own decisions about
childbearing, they have smaller (and healthier, and better educated) families.
That means the most effective means to slow growth aren’t “population”
programs at all. They include efforts to educate girls, advance women’s rights,
broaden access to family planning and other reproductive health services, and
promote sustainable, equitable development. What’s more, those are all things we
should be doing anyway.
