For billions of years our planet was devoid of life, but something transformed it into a vibrant, living planet. That something was soil. It's a much-misunderstood substance, often dismissed as 'dirt', something to be avoided. Yet the crops we eat, the animals we rely on, the very oxygen we breathe, all depend on the existence of the plant life that bursts from the soil every year.
In this film, gardening expert Chris Beardshaw explores where soil comes from, what it's made of and what makes it so essential to life. Using specialist micro-photography, he reveals it as we've never seen it before - an intricate microscopic landscape, teeming with strange and wonderful life-forms.
