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.
