Is soil actually alive? | with Frank Ashwood

Soil is home to an estimated 59% of Earth’s species, and most of us never give it a thought. Soil ecologist and photographer Frank Ashwood takes us layer by layer through the living world beneath our feet. From leaf litter to deep subsoil, meet the creatures that keep our planet running: springtails that launch faster than a blink, slime moulds that recreated Tokyo’s rail network, armoured mites that have gone without males for around 100 million years, and tardigrades that might now be on the Moon. Along the way, Frank busts earthworm myths, explains how European earthworms are invading North America, and shows how soil life is inspiring new materials and robots.
