Episode notes

The sun is one thing, but we are responsible for earth now. We might flee to another star, but it's limited, and it's all just a matter of time. Oa, i still feel that as a human being, i feel it is sad that our run is cut off - especially due to our own thoughtless actions. But this is why we can't regenerate the sun ray. Thats what i am grappling with.

Of all the scenarios that keep astrophysicist Sandra Faber up at night, it's not the Earth's increasing volcanism, the loss of photosynthesis, or even the impact of a massive asteroid. Rather, it's the collapse she's certain will result from the unbridled growth of the world's economies. Join Faber and EconTalk host Russ Roberts as they explore what the most inexorable law of physics has to do with economics and whether the world's growing economies pose a problem or provide the solution for the finiteness of planet Earth.
