Soil is essential to life on Earth, and this book explains exactly how it impacts different areas of our lives – from the link between soil and climate change, to growing the food that we eat, and why we need to protect the ground. ‘Under Your Feet’ delves beneath the Earth’s surface and explores the diverse wonders hidden there. Encounter creatures of the deep and marvel at the mind-boggling size of the humongous fungus – the biggest organism in the world. Discover all the stuff you never knew about the world under your feet, from exactly what soil is made of, to the creepy crawly creatures who make it their home. Learn how one handful of ordinary soil contains more organisms than there are people on Earth, and carry out experiments using dirt from your own back garden.
