OPINION: World Population Nearing 8 Billion

By Maria Fotopoulos

World Population Day, created by the United Nations “to focus attention on the urgency and importance of population issues,” came and passed this month. The top news results in a quick Google search on the day were all from India. And as the weekend passed, there was barely any acknowledgement in the United States of World Population Day, even as our human numbers ramp up each day.

Earth is home now to nearly 8 billion people, and we add about 81 million people to our only home each year, down from a peak of about 90 million annually in the 1980s. The U.S. population, at 330 million, has doubled since 1950 when it was 151 million.

The first World Population Day was in 1989, inspired by the Day of Five Billion, two years prior, which put the spotlight on the unprecedented human population growth on the planet. A graph often referenced in population articles shows how the human population remained relatively stable from 10,000 BC for centuries, not reaching 1 billion until the early 1800s. From there, looking at the graph, human population went parabolic. While birth rates have mostly fallen globally, Earth nonetheless is expected to provide for nearly 11 billion people by the end of this century, thanks to population momentum and regions which still have high fertility rates.

Such a lot of numbers. Do they matter?

Of course they do!

The number of people on the planet – all drawing down the resources of the planet – impacts most everything. More people means the need for more food, water, housing, energy, roads and other infrastructure – more resources of every kind. The more people there are, the less for all other species. Habitat loss and deforestation are a major cause of biodiversity loss. And habitat loss and deforestation happen why? Because of humankind, mostly.

As Al Bartlett (1923-2013), physics professor at the University of Colorado, wrote, “Can you think of any problem in any area of human endeavor on any scale, from microscopic to global, whose long-term solution is in any demonstrable way aided, assisted or advanced by further increases in population, locally, nationally or globally?”

I was born in the US and have lived in towns and cities from the East to West coasts my entire life, so my view is, understandably, US-centric and that includes an understanding of the impact of population – a learning from an early age when the Zero Population Growth movement was on everyone’s lips. But the strong voices from the 60s and 70s on the need to stabilize population have essentially gone silent in today’s America, with a few exceptions.

Virtually all US organizations that hold themselves out to be environmental organizations have abdicated their responsibility to talk about population and the very real impact on all conservation concerns. In fact, too many have been more concerned since 2016 with functioning like political organizations as their leadership and acolytes tumble down the rabbit hole of Trump Derangement Syndrome.

Several years ago I contacted the deep-pockets Natural Resources Defense Council and asked why they didn’t devote resources to population issues. Their answer was that there were other organizations better-suited to address those issues. Who? And while the Center for Biological Diversity still has a program on “Population and Sustainability,” their online magazine, The Revelator, dropped its population section.

For whatever shortcomings there may be with this year’s documentary, Planet of the Humans, by Michael Moore and Jeff Gibbs, it has revealed the elephant in the room – something a lot of environmentalists aren’t doing.

When US environmentalists, who should be at the forefront of talking about, and presenting solutions to, overpopulation – and aren’t – it’s a chimera to believe America will be the country to offer the thoughtful, reasonable and education-based solutions to the inextricably connected problems of overpopulation and environmental degradation – in our own backyard, let alone in a world of 8 billion… or 10 billion… or 11 billion people.

Maria Fotopoulos writes about the connection between overpopulation and biodiversity loss, and from time to time other topics that confound her.
