Dirt isn’t just the stuff beneath our feet. It’s the stuff of life. Welcome to our first-ever week of programming for kids!  Become a Video Lab member! http://bit.ly/video-lab 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. Roll up your sleeves. It's time to get dirty. We designed these episodes for kids ages 9-13, but we hope all of our audience enjoys them!
