“9 Billion People + 1 Earth = ?”

Andrew Revkin, Senior Fellow at Pace University and Dot Earth blogger for The New York Times

Host: Craig Cohen

After two centuries of explosive growth, the planet's population is widely seen as cresting within the next couple of generations. A best guess for the peak remains roughly 9 billion people. There are even signs that resource-sapping activities will hit a peak as well. Will we overheat or innovate, conserve or despoil, crash or round the curve with a few scrapes? Andrew Revkin, Dot Earth blogger for the New York Times, explores ways to shape and share ideas that can foster progress on a finite planet.
