More than 15,000 scientists once signed a warning that population growth ranks among the drivers pushing species toward extinction. Colcom Foundation leans heavily on that 2017 paper, published in BioScience as “World Scientists’ Warning to Humanity: A Second Notice,” to support its argument that demographic trends belong in any serious conversation about biodiversity loss.
A Pattern Across Studies
The foundation’s resource page lays out a string of research findings rather than a single source. A 2022 study in Biological Conservation found that population growth drives biodiversity loss, and separately observed that declining population density in parts of rural Europe helped enable successful rewilding projects. The 2019 Global Assessment from the Intergovernmental Panel on Biodiversity and Ecosystem Services reached a related conclusion, tying biodiversity loss to accelerating demographic and economic growth worldwide.
Colcom Foundation also cites a 2004 analysis finding that population density and species richness together explained 88 percent of the variation in threatened species across 114 countries. Research from 2017 published in the Proceedings of the National Academy of Sciences documented vertebrate population declines across 177 mammal species, attributing the pattern in part to overpopulation and overconsumption combined.
Why the Foundation Highlights This Body of Work
Colcom Foundation argues that no single study proves its case, but that the accumulation of findings across decades and continents does. The foundation funds public education built around this research, aiming to inform how conservation groups, policymakers, and everyday citizens think about the connection between human numbers and the health of ecosystems.
The foundation acknowledges that population focused conservation arguments draw skepticism in some circles. Colcom Foundation maintains that its citations are drawn from established, peer-reviewed journals rather than advocacy material, and it invites readers to examine the underlying papers directly rather than rely on summaries alone.
