Marian Tupy debunks the persistent myth that population growth will lead to the exhaustion of Earth's natural resources and the destruction of our ecosystem. He argues there are no resource constraints on what an ever-expanding humanity could accomplish  - the only constraints are the ones humans make through their own bad governance. Marian Tupy is co-author with Gale Pooley of "Superabundance: The Story of Population Growth, Innovation, and Human Flourishing on an Infinitely Bountiful Planet." He is a senior fellow at the Cato Institute’s Center for Global Liberty and Prosperity and editor of the website HumanProgress.org. Follow Marian's work on Twitter at @HumanProgress.
