SAM: Welcome to the Sound of Science on WNIJ. I’m Sam from NIU STEM Outreach.
CHRISTINE: And I’m Christine from NIU Outdoor Adventures. Ever wonder why parks and rangers insist that you stay on the trails?
SAM: I’m sure safety has a lot to do with it, but I wonder if sustainability also applies.
CHRISTINE: Yes, and that goes for every ecosystem – including deserts! Deserts have a unique system called cryptobiotic soil.
SAM: Crypto meaning hidden, and biotic meaning living so… Soil we can’t see?
