The Overpopulation Project

Over the past two centuries Earth’s human population has doubled, and doubled again, and nearly doubled yet again, increasing from 1 billion to over 7.6 billion people. This huge increase is at the root of grave global environmental problems, from climate change to mass species extinction. With help from a generous grant from the Global Challenges Foundation, The Overpopulation Project studies the environmental impacts of overpopulation and explores humane policies to end population growth around the world.
