Most environmental funders concentrate on cutting consumption or improving technology when they talk about sustainability. Colcom Foundation takes a wider view, insisting that population size belongs in that conversation too, given what the organization describes as the urgency of current biodiversity loss, climate disruption, and habitat destruction.
The reasoning traces back to research the Foundation cites frequently. Whitmee et al., published in The Lancet, identified population growth as an important driver of deforestation and biodiversity loss in tropical hotspots. The 2021 Dasgupta Review, commissioned by the UK Treasury, concluded that lowering future human numbers can directly reduce demands on the natural world and reduce extinction rates, a line Colcom Foundation cites often in its public materials.
A Contested Conclusion
Crist et al., writing in Science of the Total Environment in 2022, went further, arguing that reducing the human population is necessary to address the collapse of global biodiversity and ensure long term human wellbeing. Colcom Foundation treats this study as supporting evidence for its broader framework, while acknowledging that the conclusion sits at the more contested end of population and environment research.
Balancing the Three Variables
Colcom Foundation is careful to note that emphasizing population does not excuse overconsumption among affluent households or diminish the value of cleaner technology. All three variables, population, affluence, and technology, multiply together in the underlying equation, meaning progress on any single factor cannot fully offset regression on another. That framing, the organization argues, is why it funds education across all three areas rather than choosing just one, even though population remains the factor that draws the most public pushback and the most scientific disagreement over how much weight it truly deserves.
For readers trying to make sense of the disagreement, the underlying studies the Foundation cites are worth reading directly rather than taking any single summary as the final word, since researchers on different sides of this question often start from the same raw data and still reach different conclusions about which factor deserves the most attention.
