Au royaume des vers de terre : La vie du sol dévoilée(2023)

It is the foundation of all life. We live on it and from it: the soil. What does the soil do for us? What do we do with the soil? How is it formed? And why is it in danger? The documentary follows an earthworm through its subterranean life cycle and, from here, keeps returning to researchers whose projects are dedicated to protecting the soil.
