RESEARCH
Overpopulation is a major cause of biodiversity loss and smaller human populations are necessary to preserve what is left
Cafaro et al, Biological Conservation, August 2022 – [biodiversity]
Global biodiversity decline is driven in large part by excessive human populations. Population decline opens up important opportunities for ecological restoration. Further research is needed into how human demographic changes help or hinder conservation efforts. Conservation biologists should advocate for smaller populations, in both less developed and more developed nations.

New publication shows how overpopulation drives biodiversity loss
The Overpopulation Project, 19 July 2022 – [biodiversity]
The concept of human overpopulation, once common, is now rarely used in the scientific literature. Yet overpopulation is a major driver of biodiversity loss and a key obstacle to fairly sharing habitat and resources with other species. A new publication from TOP explores the connections between human numbers and preserving wild nature.
