Earlier this year, I worked with producer Christina Kim,

Hey, Rund, on an episode about nuclear winter theory, which is the idea that if every world power that had nukes started to actually

use them, the world would descend into nuclear winter. Think the end of the world,

a la the end of the dinosaurs.

It was a theory popularized by the astrophysicist Carl Sagan and other scientists in the 1980s.

Some credit the theory with helping to avert nuclear war at the height of the Cold War.

A new consciousness is developing which sees the Earth as a single organism

and recognizes that an organism at war with itself is doomed.

Sagan was the scientist of the time, in large part because he hosted this public media show

called Cosmos that made science accessible and, well, human. He was part scientist, part

poet, and 100% magnetic.

We are one planet.

You should check out the episode if you haven't already.
