Dune Series PHD Episode 30 Heaven and Hell: The Ecology of the Desert Planet Arrakis (Dune)
Channel: Doc Sloan's Science Fiction Station
Date: 2021-10-15

This episode investigates the world of Arrakis, later called Rakis, but forever known as Dune. Few worlds in science fiction are as well realised as the desert planet of Arrakis, home to the Fremen, the giant worms and of course, the spice, Melange.

It is the immersion in this world that Herbert uses to subtly educate his readers in ecological awareness. Not always a desert planet, and with no remaining indigenous life, Arrakis is a world changed by the catastrophic introduction of an invasive species. 

And with the arrival of a hero, it will change again.
