Since the dawn of recorded history, our living earth has been changed by everyone who spends time on it or in it from the smallest bacteria to the largest animals.

But like the brain-gut axis inside of us that we still barely understand, we've really never had the ability to see and document and even begin to ask questions about the smallest among us out in the world. In the soil, in the air, in the mud, and, of course, all the different kinds of water on this very, very watery planet. Until recently.

Thankfully, there are scientists and documentarians among us who can see and share and spark joy in a simple tablespoon of water. Who can help so many more of us who don't have access to those things, see and understand what's around us every day.

And as the world has changed so much faster than ever before, it is vital we support as much of this work as possible. Just when it is most possible. 

My returning guest today is the great Ariel Waldman.

Ariel is a National Geographic Explorer, a documentary filmmaker, an Antarctic researcher, a TED main stage speaker, NASA advisor, YouTube host, producer, and an author. Her solo expeditions in science exploration work have earned her global recognition for bridging adventure, storytelling and cutting edge science.

I'm so thankful for making all this for coming back on the show today to share news about her wonderful new six part series, Life Unearthed with Ariel Waldman, premiering in April on PBS.
