Earth’s
population grows by roughly 190,000 people per day.
On
planet Earth, world population in 2026 is 8.3 billion people,
which is four times larger than it was a hundred years ago.
Despite
this record number of humans living on the planet, world population
is expected to continue increasing throughout the 21st century,
significantly impacting planetary sustainability.
Over
the past two hundred years, the human population on the planet
has experienced unprecedented growth rates. For example, it
took thousands of years for world population to reach the
one billion mark at the beginning of the 19th century, in
1804.
In
the subsequent centuries, the growth of world population accelerated
with record high rates of demographic growth. It took approximately
123 years for the world’s population to increase from
one billion to two billion and 47 years for the world population
to double again, reaching four billion in 1974.
United
Nations population projections anticipate that world population
will continue to grow throughout the 21st century. By around
2060, world population is expected to reach 10 billion, which
is ten times the size it was in 1804. Furthermore, world population
is projected to peak at 10.3 billion in 2084 and then slightly
decrease to 10.2 billion by the end of the century.
As
the world population has grown rapidly, the geographic distribution
of billions of people across the planet has also significantly
changed since the beginning of the 20th century.
Another
significant change involves the proportion of the world’s
population living in Asia. At the beginning of the 20th century,
around 60% of the world’s population lived in Asia.
However, by the close of the 21st century, that proportion
is expected to decrease significantly to 45%.
The
proportions of the world’s population living in the
other three major regions have been relatively stable, remaining
in single digits. The proportions for Latin America and the
Caribbean, Northern America and Oceania are approximately
8%, 5% and 1%, respectively.
The
shifts in the global distribution of world population have
led to significant economic, political, social, and environmental
implications. Despite these important consequences, much attention
in the media, business boardrooms, and government offices
is focused on low fertility rates and the resulting population
decline in many countries.
It
is the case that more than half of the countries worldwide
have fertility rates below replacement levels, leading to
population decline and demographic ageing. However, the media
often portrays a stable or smaller population in a negative
light.
The
consequences of the ongoing population growth, projected to
reach 10.3 billion people by 2084, will lead to a complex
mixture of global problems that many governments, unfortunately,
typically ignore, dismiss, or minimize
In
such reporting, terms like “weak” or “anemic”
are used to describe moderate population growth, while “flat”
or “stalled” are used for stable population. Additionally,
those who warn of depopulation often predict a future crisis
instead of discussing any positive relief from current environmental
and climate concerns or the benefits for women and working
families.
Many people, especially traditional economists and right-wing
politicians, assume that population growth is essential for
a flourishing economy. These individuals advocate for population
growth because they believe it drives economic growth, increases
the labor supply, and stimulates consumption.
The
concern about the birthrate crisis is often fueled by those
who benefit from a growing population. These individuals often
provide information or central messages, such as population
collapse, failing economies, demographic crisis, and human
extinction, which are then picked up by the media and lead
to misleading headlines.
Moreover,
many government officials are calling for increased population
growth through higher fertility rates and implementing policies
and actions to support such outcomes. These calls, policies,
and actions are primarily driven by concerns over demographic
ageing, declining workforces, and economic sustainability.
In
essence, their message is that a growing population leads
to a larger economy, more entrepreneurs, market expansion,
and innovation. Additionally, some government officials choose
to focus on women and blame them for their country’s
low birth rates.
In
contrast, a stable population is often viewed as stagnant.
The demographic ageing of populations and increased human
longevity are seen as problematic, leading to a “demographic
winter” with significant financial stresses on government
budgets for pensions and health care for older individuals.
While
the world’s population of 8.3 billion is projected to
continue growing throughout most of the 21st century, low
fertility rates and demographic ageing are seen as challenges
rather than accomplishments.
Additionally,
as the planet’s environmental and climate crises accelerate,
large portions of society continue to ignore the fact that
a world with more than 8 billion people is a critical factor
driving them. These groups typically dismiss research findings
indicating that a world population of 8 billion, which is
continuing to increase, drives climate change, ecological
disruption, rising sea levels, biodiversity loss, habitat
destruction, resource scarcity, and food insecurity.
For
example, global wildlife is currently facing a worsening crisis.
The most recent United Nations assessment warns that nearly
half of the world’s migratory animal species are declining
due to human activity, habitat destruction, and climate change.
Moreover,
melting glaciers in Antarctica are hastening sea-level rise
in coastal cities. The Thwaites Glacier, in particular, is
melting at an alarming pace. If it were to break apart completely
and collapse today, it could raise global sea levels by 2
feet in the next few decades, affecting tens of millions of
people worldwide.
In
summary, the world’s population is currently at a record
high of 8.3 billion and is expected to continue growing throughout
the 21st century, significantly impacting planetary sustainability.
The
consequences of the ongoing population growth, projected to
reach 10.3 billion people by 2084, will lead to a complex
mixture of global problems that many governments, unfortunately,
typically ignore, dismiss, or minimize. These problems include
resource strains, increased conflict, environmental damage,
climate change, sea level rise, habitat destruction, biodiversity
loss, food insecurity, increased unauthorized migration, and
greater societal vulnerabilities.
