The human population is just about to reach seven billion. Yikes! We talk to the experts -- Polyannas, Cassandras and in between -- about how many of us Mother Earth can handle.
The UN says next week, maybe on Halloween, the world population will hit seven billion humans. That’s a whole lot of homo sapiens. It took us forever to hit the first billion, just after 1800. We’ve added four billion in just the last fifty years. Now, seven.
Can the planet manage this population of us? Doomsayers have long been wrong, but now some of the very things that saved us – fossil fuels – are croaking the environment. So what about eight billion? Nine? Ten?
This hour On Point: seven billion humans, and the planet we share.
