Episode notes

Our home right now is the earth. It might eventually be somewhere else in the galaxy, but it probably isn't outside the galaxy. On a cloudless night in a desolate place, you're still only seeing a hundred billionth of the number of starsin in the universe. We have some time to think about if we could survive as human beings until then.

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.
