The book, The hidden half of Nature: The Microbial Roots of Life and Health, is an exploration of how microbes are transforming the way we see nature and ourselves. It reveals why good health—for people and plants—depends on Earth’s smallest creatures. Nurse Rona Renner interviews the authors, David Montgomery and Anne Biklé, about their insights into the similarities between plant roots and the human gut.
