Subterranean Civilizations (Narration Only)

Historically humanity has often taken shelter in caves or underground, and it is often thought we might do so again, on other worlds, in event of disasters, or simply because we run out of room on the ground above. In this episode we'll explore the concept of building underground, from simply subways and basements to advanced bunkers or entire cities beneath the Earth.
