The Overpopulation Project studies the causes of human overpopulation and the role ending population growth can play in dealing successfully with global environmental and social problems. Believing that much of this century’s projected population increase can and should be avoided, we also explore humane policies to end population growth sooner rather than later. Our interdisciplinary work, straddling the disciplines of ecology, demography, policy analysis and environmental ethics, is made possible by generous funding from the Global Challenges Foundation and our home institutions: Colorado State University and the University of Gothenburg. Our recent scholarly reports include the following:
