Discover the surprising biodiversity of soil, and how its microbes help support all life on Earth. -- It may not appear very lively six feet underground, but a single teaspoon of soil contains more organisms than there are human beings on the planet. From bacteria and algae to fungi and protozoa, soils are home to one quarter of Earth’s biodiversity. And perhaps soil’s most important inhabitants are its microbes. Carolyn Marshall digs into how soil’s invisible helpers support all life on Earth. Lesson by Carolyn Marshall, directed by Ivana Bošnjak and Thomas Johnson.
