Welcome to Earth

On a remote island in the Pacific, Will Smith descends into the heart of an active volcano to investigate sounds beyond human hearing. Will discovers that everything on our planet creates its own unique sound—even if we can’t always hear it.

Thirty years ago, Will Smith was mesmerized by a photo of the incredible wildebeest migration across the Serengeti in a National Geographic magazine. Now he visits those same wildebeests and discovers an amazing survival strategy.

Will explores the Namibia Desert, where both the landscape and time seem to have stood still for over 50 million years. Will discovers that humans can only see a small sliver of what’s moving around us because everything on the planet is happening either too fast or too slow for us to perceive.
