Total human population over time

Our Motivation

People are overstressing the Earth: using too many resources, generating too much waste, and leaving polluted landscapes and empty seas in our wake. But this is the only home we have. Our descendants will depend on Earth’s ecosystem services for their health and well-being, just as we do. Ten million other species also need sufficient habitat and essential resources to survive and thrive. We have no right to extinguish them ; instead, we have a responsibility to create ecologically sustainable societies that allow all Earth’s life forms to flourish.


Limiting human numbers must be part of this effort. Yet environmentalists rarely acknowledge this—either because we think population growth is no longer a problem, or because we think the problem will solve itself. Neither is true. Excessive family size sends tens of millions of children to bed hungry each night in the developing world, where rapid population growth stresses scarce water, food and space resources beyond safe limits. Meanwhile continued population growth leads to deforestation, ailing coral reefs , and paved over farm lands and wetlands. Around the world, most national populations continue to grow and the United Nations projects a massive increase of 3.5 billion more people by 2100.

The Overpopulation Project studies the environmental impacts of overpopulation in an effort to remind environmentalists, scientists and policy makers of the contributions ending population growth can make in dealing successfully with global environmental problems. Believing that much of this century’s projected population increase could be avoided with the right public policies, it also explores humane policies to end population growth sooner rather than later.

A Scientist’s Warning to humanity on human population growth

One needs only to peruse the daily news to be aware that humanity is on a dangerous and challenging trajectory. This essay explores the prospect of adopting a science-based framework for confronting these potentially adverse prospects. It explores a perspective based on relevant ecological and behavioral science. The objective is to involve concerned citizens of the world in this enterprise. The overall objective is to maintain Planet Earth as a favorable home for the future of humanity. Nine ecological principles explain one major aspect of what is happening and provide critical guidelines for appropriate action. Nine social behaviors explore how we might integrate social science insights with those from ecology. Twenty predictions are proposed based on these ecological and social science principles plus existing trends. If these trends are not vigorously and courageously confronted, we will likely be on track for the demise of our civilization. As we examine these challenges, our job will be especially complicated because a major segment of humanity is not prepared to accept evidence based on science, and this generates much resistance to any efforts directed toward effective control of current and future challenges. In these complex circumstances, we must remain as cooperative and optimistic as possible so that we can promote the needed willpower and ingenuity.

This essay has broad support as it is a contribution to the Scientists’ Warning to Humanity Program of the Alliance of World Scientists ( Ripple et al., 2017 ).

1. Introduction

Planet Earth is an absolutely amazing place. An apparent rarity in the universe, it possesses the appropriate physical conditions to support life. As a result it hosts a tremendous variety of living creatures which we recognize and classify as various species. In relatively recent times, human life evolved, and in large part due to our extraordinary intelligence, has become the dominant life form on the planet. With nuclear power technologies, we are now capable of destroying all complex life forms, including ourselves. Our dominance is recognized by the acceptance of the term Anthropocene which proclaims that we have entered a human dominated planetary phase. Our numbers are projected to increase from an estimated 7.6 billion to 10 billion by 2050 ( Baillie and Zhang, 2018 ). Human caused species extinctions have also reached an unprecedented rate such that we are generally viewed as causing the sixth mass extinction episode for the planet. A recent effort to photograph human impacts on land use over the entire globe from 1992 to 2015 documents this rapidly increasing global-scale impact on land areas ( Nowosad et al., 2018 ). The inevitable questions for humanity at this stage in our history are: “Does this matter for our species?” “Does this rapid increase in numbers along with its corresponding expansion of our utilization of the Earth’s land area matter?” What does it mean for us?” Maybe it is merely a signal that we are a very successful species, and we can celebrate our good fortune. On the other hand, perhaps it is a signal that we are over-exploiting the Earth’s resources and we should seriously be preparing for a population crash. Or, are there still other scenarios? In the following two sections of this essay, we will explore these questions from the perspective of ecological science and then again from behavioral science. Subsequently, we will look for lessons learned by considering 20 predictions that emerge from our analysis.

2. Relevant ecological principles

Nine established principles of ecological science that are relevant to the circumstances we face are as follows:

3. Relevant social behaviors

The following nine social behaviors can and should be recruited to help humanity respond to the ecological impacts that will surely endanger human civilization if current trends are allowed to continue.

4. Realistic prospects and problems

Obviously we need to muster all our resources and social skills to prevent continuing in our currently unsustainable trajectory. Equipped now with an ecological and behavioral framework, we can begin to carefully construct guidelines to inform our future efforts. A reasonable place to begin would seem to be an outline of our goals for humanity in the immediate future. Do we accept a fate of massive poverty, massive mortality from wars, terrorism, and disease, and uncontrollable migrations to the places where basic resources are still available? This is our current trajectory ( Brown, 2006 ; Heal 2017 ; Kopnina and Washington (2016) ; Stokstad 2019 ). We can assume, I hope, that we would prefer a future that features a comfortable standard of living with minimal disparity among individuals and social groups, high levels of education, and democratic organizational structures for social groups at all levels of organization. In this way, everyone can feel they have input into decisions being made that likely will affect them. Especially important is respectful coexistence of diverse cultures and world views.

In the recent past, there has been much discussion as to whether our deteriorating situation should be blamed mainly on human population growth or whether affluence and pollution should share as major contributors ( Ehrlich and Holdren 1971 . Actually, these three factors interact in complex ways. For example, while improving the standard of living of people everywhere is clearly a desired objective, this certainly would add to the consumption of renewable and non-renewable resources. On the other hand, if affluence were more equally distributed than it currently is, it would improve the situation so that people in general are more content with their lives and hence are more likely to be cooperative and productive. Pollution of our environment also reduces our standard of living through its negative impacts on our health, and by increasingly deleterious impacts on our agriculture, parks, and natural areas. This in turn reduces the health benefits of natural areas ( Weinstein et al., 2015 ), and diminishes the rate of replenishment of renewable resources.

An often heard argument is that technological advances will allow us to overcome the negative effects of population growth. Technology can and certainly will contribute to a slowing of the current negative trends. However, at this time in our history it is apparent that rapid human population growth along with out-of- control climate change will not only quickly cancel out many of the benefits for humans that technology may contribute, but it will continuously add new challenges as population growth, resource depletion, and climate change continue. Mann (2018) engagingly discusses this dichotomy of prevailing beneficial natural processes dominating our future versus a technology based “green revolution.” Probably some combination of these two survival strategies will prevail. The reality, however, is much more complicated. Superimposed on these two approaches, we face the real possibility that current and future climate changes will force humanity worldwide to confront widespread disruption of human communities and ecosystem services, not to mention negative impacts on biodiversity ( Norgaard, 2010 ; Nolan et al., 2018 ). For example, we can anticipate warming climates increasing crop losses to insect pests, especially at temperate latitudes ( Deutsch et al., 2018 ). Moreover, it is especially important that we plan for anticipated extreme weather events and catastrophic fires. An example of a positive recent research finding is that restoring large grazers to depleted range lands can blunt the impacts of major fires in those situations ( Pennisi, 2018 ).

Hopefully, the negative projections might increase the awareness of the public and governments regarding the necessity to confront the drivers of climate change more vigorously. Inevitably, this will incorporate an increasing focus on slowing of human population growth. Unfortunately, many humans, probably more than half, are opposed to any plan that would involve slowing and eventually stopping human population growth. There are many reasons for this point of view that makes folks unwilling to confront the risks we collectively face. One important reason for this reluctance is that since the late 1970’s, most world cultures have moved toward rewarding individual benefits over supporting the common good. This trend compromises the feeling of cooperation within the social groups to which we all belong and depend on for our survival ( Reich, 2019 ). More troublesome is the realization that, as mentioned, many folks view any efforts to contain population growth as homicide, etc. In reality, efforts to control our runaway population growth are precisely and explicitly the opposite. We want to improve the welfare of people everywhere, and strive to eliminate poverty, racism and other forms of xenophobia. Lastly, we would want to maintain an individual’s freedom to control their own reproductive activities. The only constraint on an individual’s behavior is that it must be compatible with the needs of the social groups to which they belong.

5. Realistic predictions

Realistic predictions can be derived from ecological and sociopolitical knowledge as well as from already existing trends, and can serve to motivate appropriate actions. An example of a well-established existing trend is that of global warming. Scientists have been concerned about this human caused trend at least as far back as 1966 ( Landsberg, 1970 ). Predictions, however, are inherently risky, especially given the power of human ingenuity to address perceived problems. Three examples of failures to predict accurately are: 1) the much faster than predicted sea level rises associated with the deltas of large river systems ( Voosen, 2019 ); 2) The unanticipated huge wave of unusually hot water that beginning five years ago swept across the Pacific Ocean causing widespread havoc with fisheries, seabird populations and whales, and is currently developing again ( Cornwall, 2019 ); and 3) Concentrations of the greenhouse gas methane are increasing in the atmosphere more rapidly than predicted ( Mikaloff Fletcher and Schaefer, 2019 ). In general, modern chaos theory supports the generalization that when dealing with complex systems, longer term predictions are more reliable because they are guided predominately by deterministic processes, while shorter term predictions are less reliably accurate since they often are strongly influenced ly by random processes. In general it will be very difficult to predict the ability of species and he communities of which they are a part to adapt successfully to the rapidly changing conditions in our future ( Bridle and van Rensburg (2020) . In this cautious spirit, the following 20 predictions are offered as potential warnings.

6. Guidelines

Here are six guidelines for all concerned citizens of this planet that summarize recommended approaches for achieving a sustainable human civilization. In addition, please note that Kopnina et al. (2016) have provided a most welcome list of human behaviors that non-coercively will help to guide us to population stability.

A final thought: Nine decades ago, Anne Frank gave us this wisdom: “How wonderful it is that nobody need wait a single moment before starting to improve the world.”

Scientists more worried than public about world’s growing population.

Total World Population

Over the course of history, many scientists and activists have raised alarm about population numbers that only increase every year.

When the English scholar Thomas Malthus published An Essay on the Principle of Population in 1798, the number of people around the world was nearing 1 billion for the first time. “The power of population is indefinitely greater than the power in the earth to produce subsistence for man,” he wrote then.

World Population Growth

In 2015, the global population is an estimated 7.3 billion, according to the United Nations , and many of Malthus’s and Ehrlich’s predictions have yet to come true or have been proven false (such as the “increasing” death rate, which has actually decreased ).

According to a pair of 2014 Pew Research Center surveys , however, today’s scientists are more likely than the general American public to be concerned about population growth, though not necessarily to the extent that Malthus and Ehrlich were.

Views of Population Growth

Americans used to be much less concerned about population growth, according to Gallup polls: In 1959, three-quarters (75%) of Americans had heard about the “great increase in population” predicted for the world during the coming decades, but just 21% of Americans said they were worried about it. And when comparing population concerns with a list of global threats,  a 1997 Pew Research Center poll  showed that Americans were more worried about other potential risks.

Looking ahead, it’s still unclear what the population trajectory will be. The UN says that population will continue to grow throughout the 21 st century, predicting with 80% confidence that it will reach somewhere between 9.6 billion and 12.3 billion people by 2100.

Growth is expected to occur mostly in Africa, and abate in the Americas, Europe and parts of Asia, especially as families in more-developed nations have fewer children than they used to have. In many countries in the latter regions, the total fertility rate has dropped below the “replacement rate” of about 2.1 lifetime births per woman. The total fertility rate in the U.S. , for example, fell to 1.86 in 2013.

8 Billion Opportunities: On November 15, 2022 humanity's population eclipsed 8 billion people. What Does This Mean?

Overpopulation: Cause and Effect

A large group of people walking in a city

Conversations about overpopulation can quickly become controversial because they beg the question: Who exactly is the cause of the problem and what, if anything, should be done about it? Many population experts worry discussions around overpopulation will be abused by small-minded people to suggest some are the “right people” to be on the planet (like themselves), and some people are “the wrong people” (usually people in poverty, people of color, foreigners, and so on—you get the drift). But there are no “right” or “wrong” people on the planet, and discussing the problems of global overpopulation can never be an excuse, or in any way provide a platform, for having that type of conversation.

Each human being has a legitimate claim on a sufficient and fair amount of Earth’s resources. But with a population approaching 8 billion, even if everyone adopted a relatively low material standard of living like the one currently found in Papua New Guinea , it would still push Earth to its ecological breaking point. Unfortunately, the “average person” on Earth consumes at a rate over 50% above a sustainable level. Incredibly, the average person in the United States uses almost five times more than the sustainable yield of the planet.

When we use the term “overpopulation,” we specifically mean a situation in which the Earth cannot regenerate the resources used by the world’s population each year. Experts say this has been the case every year since 1970, with each successive year becoming more and more damaging. To help temper this wildly unsustainable situation, we need to understand what’s contributing to overpopulation and overconsumption and how these trends are affecting everything from climate change to sociopolitical unrest.

The causes of overpopulation.

Today the Earth is home to more than 7.8 billion people . By 2100 the population is on track to hit 10.8 billion , according to the United Nations — and that’s assuming steady fertility declines in many countries. Interestingly, if extra progress is made in women’s reproductive self-determination, and fertility falls more than the United Nations assumes is likely, the population in 2100 might be a relatively smaller 7.3 billion.

For now, the world’s population is still increasing in huge annual increments (about 80 million per year), and our supply of vital non-renewable resources are being exhausted. Many factors contribute to these unsustainable trends, including falling mortality rates, underutilized contraception, and a lack of education for girls.

Falling Mortality Rate

The primary (and perhaps most obvious) cause of population growth is an imbalance between births and deaths. The infant mortality rate has decreased globally, with 4.1 million infant deaths in 2017 compared to 8.8 million in 1990, according to the World Health Organization (WHO). This is welcome public health news, of course.

At the same time, lifespans are increasing around the world. Those of us who are alive today will likely live much longer than most of our ancestors. Global average life expectancy has more than doubled since 1900 , thanks to advancements in medicine, technology, and general hygiene. Falling mortality rates are certainly nothing to complain about either, but widespread longevity does contribute to the mathematics of increasing population numbers.

Underutilized Contraception 

The global fertility rate has fallen steadily over the years, down from an average of 5 children per woman in 1950 to 2.4 children per woman today, according to the UN Population Division . Along with that promising trend, contraceptive use has slowly but steadily increased globally, rising from 54% in 1990 to 57.4% in 2015. Yet, on the whole, contraceptive use is still underutilized. For example, according to the WHO, an estimated 214 million women in developing countries who want to avoid pregnancy are not using modern contraceptives.

These women aren’t using contraceptives for a variety of reasons, including social norms or religious beliefs that discourage birth control, misconceptions about adverse side effects, and a lack of agency for women to make decisions around sex and family planning. An estimated 44% of pregnancies were unintended worldwide between 2010-2014. Getting more women the access and agency to utilize family planning methods could go a long way in flattening the population curve.

Lack of Female Education    

Although female access to education has increased over the years, the gender gap remains. Roughly 130 million girls worldwide are out of school currently, and an estimated 15 million girls of primary school age will never   learn to read and write, compared with 10 million boys.

Increasing and encouraging education among women and girls can have a number of positive ripple effects, including delayed childbearing , healthier children, and an increase in workforce participation. Plenty of evidence suggests a negative correlation between female education and fertility rates.

If increased female education can delay or decrease fertility and provide girls with opportunities beyond an early marriage, it could also help to mitigate current population trends. 

The Effects of Overpopulation

It is only logical that an increase in the world’s population will cause additional strains on resources. More people means an increased demand for food, water, housing, energy, healthcare, transportation, and more. And all that consumption contributes to ecological degradation, increased conflicts, and a higher risk of large-scale disasters like pandemics.  

Ecological Degradation 

An increase in population will inevitably create pressures leading to more deforestation, decreased biodiversity, and spikes in pollution and emissions, which will exacerbate climate change. Ultimately, unless we take action to help minimize further population growth heading into the remainder of this century, many scientists believe the additional stress on the planet will lead to ecological disruption and collapse so severe it threatens the viability of life on Earth as we know it. 

Each spike in the global population has a measurable impact on the planet’s health. According to estimates in a study by Wynes and Nicholas (2017) , a family having one fewer child could reduce emissions by 58.6 tonnes CO2-equivalent per year in developed countries.

Increased Conflicts 

The scarcity brought about by environmental disruption and overpopulation has the potential to trigger an increase in violence and political unrest. We’re already seeing wars fought over water, land, and energy resources in the Middle East and other regions, and the turmoil is likely to increase as the global population grows even larger.

Higher Risk of Disasters and Pandemics 

Many of the recent novel pathogens that have devastated humans around the world, including COVID-19, Zika virus, Ebola, and West Nile virus, originated in animals or insects before passing to humans. Part of the reason the world is entering “ a period of increased outbreak activity ” is because humans are destroying wildlife habitats and coming into contact with wild animals on a more regular basis. Now that we’re in the midst of a pandemic, it has become clear how difficult it is to social distance in a world occupied by nearly 8 billion people.   

Discover the real causes and effects of overpopulation

What can be done .

When addressing overpopulation, it’s crucial to take an approach of providing empowerment while mobilizing against anybody advocating for the use of coercion or violence to solve our problems. The combined efforts of spreading knowledge about family planning, increasing agency among women, and debunking widely held myths about contraception will measurably change the trajectory of the world’s population.

As we carry out our work at Population Media Center (PMC), we see first-hand that spreading awareness about family planning methods and the ecological and economic benefits of having smaller families can change reproductive behavior. For example, listeners of our Burundian radio show Agashi (“Hey! Look Again!”) were 1.7 times more likely than non-listeners to confirm that they were willing to negotiate condom use with a sexual partner and 1.8 times more likely than non-listeners to say that they generally approve of family planning for limiting the number of children.

At PMC we harness the power of storytelling to empower listeners to live healthier and more prosperous lives, which in turn contributes to stabilizing the global population so that people can live sustainably with the world’s renewable resources.
