Today, on Halloween no less, the Earth welcomed the baby who tipped world population over the 7 billion mark.
I probably wouldn’t have known much about the topic of world population but for a fluke as I prepared to graduate from the University of Texas Permian Basin the summer of 1974. To my surprise, I was told I needed three more hours of science.

It had been a long 12-year road for me, what with three children to care for, a five-year stint teaching Head Start, and other detours along the way. Finally, I thought, I’d be done by the end of June.
Once I got the bad news, I looked for the easiest science course I could find, preferably one without the usual fourth hour for lab. Ecology, yes! The class was co-taught by Professor Ed Kurtz, now retired, who remains a great friend and a wonderful role model for someone who still “wears the shirt” of his convictions by volunteering for environmental and reproductive rights causes.
Yes, they were talking about world population back in 1974, when there were only 4 billion people inhabiting planet Earth. We’ve almost doubled in less than 40 years.
What’s more striking, it took from the beginning of time until 1800 for the world’s population to reach the one billion mark. The rapid growth since then is because we have given ourselves a great deal of death control–we’re living longer and lowered infant mortality significantly—and that’s good. But we haven’t balanced that out with equal attention to birth control, food and other resources, and ecological conservation to sustain the growing population.
There have been many any successes to be sure, but the world will strain to support the 9 billion people who will probably be living here by 2050, if current trends continue.
Over the past few weeks, there have been many news reports on this Day of 7 Billion. One of the best was by AP’s Dave Crary.
But I especially want to share with you in full this piece written for RH Reality Check by Roger-Mark De Souza, Vice President for Research and Director of the Climate Program for Population Action International. De Souza personalizes the story. It’s clear that population issues are really about people, and that the status of women in society is central to determining the future.
Sex and Sustainability: Reflections for My Son Nick
“Are we going to talk about sex again?!” screamed my 12-year old son, Nick, as he ran down the stairs, away from me. That was five years ago and I had just sat down with him to have one of our father-son talks, this time about sex and sustainability.
Now Nick, a rising senior, is preparing for college at the same time as the global community is preparing for an important landmark of its own: the United Nations predicts that by October 31, world population will reach 7 billion.
The confluence of these two events gives me reason to think about the world Nick is inheriting from my generation, and makes me consider what I can say to him as he heads off to college.
This World of 7 Billion
I try to get my head around it. It’s a world of 7 billion people. With greater connectivity than I could have ever dreamed possible. A world of widening disparities and growing environmental degradation. A world with a changing climate. A world of crashing economic markets and changing debt ceilings.
It’s also a world of finite resources and growing demand.
Consider water. As the world’s population grows, the demand for water mounts and pressure on water resources intensifies. Unfortunately, the areas where water is most scarce are typically those with high population densities and rapid population growth. Population growth limits the amount of water available per person, and drives people into marginal regions – which are also water-stressed.
Consider forests: The top 10 countries experiencing the greatest loss of forest cover generally have large, fast-growing populations. Increased demand for fuel wood is driving a great deal of deforestation in the populous regions of East Africa and South Asia. Often, forests are cleared by migrant families that have been forced out of their crowded areas of origin.
Consider habitat loss: Global population is projected to grow to anywhere between 8 billion and 11 billion by the middle of the century, with much of that growth expected to take place in the humid tropics that harbor the planet’s richest biodiversity. Habitat loss is generally greatest where population density is highest. Urbanization also takes a toll: sprawling cities have led to the disappearance of numerous habitats. And city-dwellers consume more, increasing pressures on ecosystems.
Consider changing climate: An analysis by the organization where I work, Population Action International, identified 33 population and climate change “hotspots.” These fast-growing countries are extremely vulnerable to climate change, in part because they face water shortages and declining agricultural production. The average number of children born to each woman in hotspot countries is five, and the average population growth rate is 2.5 percent – a rate that, if unchanged, would result in a doubling of the population in just 29 years.
But continued population growth is not inevitable: In these hotspot countries, an average of one in four married women would like to avoid pregnancy, but is not using modern family planning. Addressing that “unmet need” for contraception would slow growth, reduce pressure on resources, and increase resilience. Investing in a woman’s right to decide how many children she can have, when she can have them, and ensuring that she can have them safely is fundamental.
Reflections for Nick
These challenges may seem remote to my son, Nick, growing up in suburban Virginia. But they will shape the world he inhabits in profound ways. So what can I share with Nick as he launches into this world of seven billion?
“Son, as you continue to develop into a young man who will assume responsibility in the world, recognize the following:”
1. Understand the complexity of the world as you feel it. The starting point for your career and your contribution must be to recognize the world’s complexity and find your place within it. The United Nations projects that when you are 56 years old, in 2050, world population may have reached 9.3 billion. The size, shape, and form of that population matters to you as it will affect your health, well-being, and security.
2. Recognize the value of women. I know that you already know the value of young women. I want you to know that the decisions these women make have a profound effect on the world. Ensuring that women can decide how many children they want, when to have their children, and the ways that they invest in those children is one of the most important moves we, as a society, can make. It is at the core of our lives. Recognize this and play your part as a man, particularly if you’re lucky enough to get married, and perhaps even be the father to a daughter.
3. Incorporate the needs of communities to ensure value-added. As you think of your areas of study and learning, be sure to respond to real demands in order to add value. Don’t assume that you know what others need. Discover the genuine needs both of individuals and communities, and then respond.
4. Size (and scale) matter. Your world is inherently more complex and connected than I could ever have imagined. It will only get more so. Determine where your impact can be most felt, and focus on the best way to have an impact at that scale. And, be sure to recognize how you can leverage innovation to maximize your impact.
5. Do the right thing. You know in your heart what’s right. Infuse that sensibility in your contributions to the world. Individual rights are fundamental to human well-being. Don’t confuse rights and wants. Make your contribution one that’s based in a rights approach, but make it practical and palatable. Go with your convictions.
As I share these reflections with Nick, the world reaches the seven billion population landmark, and my family reaches a personal landmark of launching a child out into this expanding world, I’m reminded of a question from my younger 16-year-old son, Miki. Standing at the front door as he signed for a package from the mailman, he screamed: “Dad, did you order these condoms with endangered species slogans on them?”
The conversation continues….
I strongly encourage you to read RH Reality Check’s series on the Day of 7 Billion and related topics. Share your thoughts about global population and its challenges here. Are you an optimist or pessimist about what the future holds? What do you think are the most pressing problems and best solutions? Is population growth scarier than Halloween or do you think we will achieve balance between population and the resources necessary to sustain ourselves?
