The secret history of dirt, explained to kids

KidsWeek Thumbs Clean.0

It’s not just the stuff beneath our feet. It’s the stuff of life.

Dirt. We think we know it. But do we really?

What if dirt isn’t just the stuff we knock off our soccer cleats and brush off our knees? What if it’s the key to life on planet Earth?

Dirt is alive. It’s full of billions of creatures so small you can’t even see them under a microscope. For 10,000 years, dirt has helped humans convert the limitless energy of the sun into the plants and animals we eat to keep us alive.

Dirt has been good to us. But it turns out, we haven’t been very good to the dirt.

This is the story of how dirt helped build civilization, only to get stabbed in the back by us. We’ll explore how humans zapped the life out of dirt in just a few short centuries in the hopes of getting rich, and how those mistakes are coming back to haunt us. And we’ll get our hands dirty with a farmer who has figured out how to nurse sick dirt back to health.

Roll up your sleeves. It’s time to get dirty.
