Our world relies on an invisible realm that we are just beginning to understand. In the book The Hidden Half of Nature, geologist David R. Montgomery and biologist Anne Biklé argue that Earth's tiniest creations—microbes—can radically change the way we grow food, what we eat, and how we practice medicine. The book shares Montgomery and Biklé's efforts to turn a barren plot of land into a thriving garden, as well as Biklé's battle with cancer. It explores the science and history of agriculture and immunology, showing how microbes can offer powerful solutions to the problems plaguing modern agriculture, as well as our own bodies. A compelling narrative, The Hidden Half of Nature reveals how we can restore the earth's fertility and defeat chronic diseases.
