... or, for this week only, The World Beneath Us
Narrated by David Attenborough
A worm's eye view of life underground. Using special camera techniques, we travel down a mole tunnel to see how a mole excavates and how it catches worms; we see the tiny animal forms that live in the watery film around soil particles; we see species so numerous that there can be up to 20 million of them under each square metre.
It was in 1777 that Gilbert White drew attention to the actions of earthworms in improving soil fertility. Two centuries later, scientists are still unravelling the mysteries - and discovering the importance - of earthworms and the animal community that makes up The Underground Movement
