2022 saw record amounts of ink spilled and electrons broadcast about the chief environmental disorders of our time – climate change and biodiversity loss – while the global population surpassed 8 billion people. Compared to past years, it seemed as if the media did a somewhat better job connecting the dots between the first two problems and the third one – or was that just our wishful thinking?

This year TOP continued our research and public outreach on the population/environment connection. Our work was made possible, in part, by generous financial support from Dan Carrigan and The GAIA Initiative for Earth-Human Balance, Dick Smith in Australia and Dag Lindgren in Sweden. We are grateful for this support! If you would like to help fund TOP’s efforts, feel free to contact us.
During 2022, we lost several giants of the population movement. In August, László Szombatfalvy passed on after a long, successful career in business and philanthropy. László founded the Global Challenges Foundation, whose seed grant helped start The Overpopulation Project five years ago. We appreciate his kind moral and financial support, including a personal donation in 2021.
In September, we lost Dave Foreman, the founder of Earth First! and author of Man Swarm: How Overpopulation Is Killing the Wild World. Dave was an uncompromising defender of wilderness and unrelenting critic of human chauvinism. A month later, in October, Herman Daly died, founder of ecological economics and author of For the Common Good: Redirecting the Economy toward Community, the Environment, and a Sustainable Future. Dave and Herman were leaders in American wildlife conservation and heterodox economics, respectively, from the 1970s onward. They always insisted on the need to limit human numbers and fairly share Earth’s resources with other species.
We will miss these giants and are grateful for having known and learned from them. At the same time, we happily note the many Millennial and Gen Z voices rising up to join us old-timers in speaking truth to population complacency. The latter includes our own Pernilla Hansson, who completed her Masters degree in conservation biology at Gothenburg University this year. Thanks to Pernilla for all her good work over the past three years, including writing our series of blogs on rewilding success stories.
Speaking of Gen Z, Jeanne Belly from Leiden University visited TOP in early spring on an Erasmus internship. Thanks to Jeanne for writing the blog Strategies to stop short of 9 billion. Also on the positive side of the ledger, this year saw the founding of the European Alliance for a Sustainable Population. The alliance is an international platform that promotes science-based awareness about the implications of a sustainable population.
During 2022, TOP members published or coauthored seven peer-reviewed papers on population-related issues. This work explored both the science and ethics of population growth as they relate to climate change, biodiversity loss and ecological disruption generally, and population policy in both wealthy and poorer countries. Publications included:
Overpopulation is a major cause of biodiversity loss and smaller human populations are necessary to preserve what is left. Philip Cafaro, Pernilla Hansson, and Frank Götmark. Biological Conservation 272 (2022): 109646.

Op-eds and Blogs
How common are opinion pieces on population or overpopulation in large-circulation newspapers around the world? TOP’s work in Sweden shows it is possible to publish such pieces, by careful writing and marshalling basic facts to convince editors of the importance of debate around population matters. Over the last five years, Frank and fellow population-aware Swedes have published about 15 op-eds in Sweden’s three largest morning newspapers and two largest tabloids.
Perhaps such population debate occurs also in other countries, in print or online. If so, let us know! We may translate from other languages and share with our readership.
In 2022, TOP produced 49 blogs on a wide variety of topics. Highlights included:
Herman Daly, Population and cheap labour
Jane O’Sullivan, World population is growing faster than we thought
Pernilla Hansson, Breaking boundaries but not population taboos
Gaia Baracetti, The per capita fallacy
Frank Götmark et al., Time for Sweden to resume focus on international family planning aid
Philip Cafaro, Population in the IPCC’s new mitigation report
In addition to contributions from the TOP core team (Frank, Phil, Jane and Pernilla), we are grateful to the following contributors: Valorie Allen, Malte Andersson, Nandita Bajaj, Gaia Baracetti, Michael Bayliss, Verena Brunschweiger, Herman Daly, Johanna Deinum, Celine Delacroix, Carter Dillard, Jan Gregus, Richard Grossman, Fons Jena, Ian Lowe, Karl-Erik Norrman, Björn Olsén, Lucia Tamburino, Kelvin Thompson, Nicola Turner, Carl Wahren, David Walker, Jan van Weeren, Nordhild Wetzler, Anders Wijkman and Stephen Williams.
We are also grateful to you, our readers, whose hundreds of comments and emails kept us thinking throughout the year. Thanks for sharing your opinions! We look forward to continuing the conversation in the new year.
