This vast, fascinating ecosystem is vital for the health of the planet but remains largely unstudied. In this episode we’re joined by Dr Frank Ashwood, a lecturer in ecology and entomology at Lincoln University, New Zealand, to talk about his latest book, The World Beneath Our Feet – The Hidden Life of Soil and Why it Matters to us All. He tells us how more than half of the planet’s biodiversity is found living within soil, how the animals that live underground have inspired innovations in medicine and technology and how we may be able to use our knowledge of soil biology on Earth to help us in our quest to establish colonies on other planets.
