As a rule, we try not to think too much about our poop. It’s one of the most taboo topics in our society, and our sewer systems are designed to keep it out of sight as much as possible. And yet, poop is a treasure trove of resources that we can use to make the world better. Scat can cure diseases and protect us against several major health concerns, aid in forensic and medical investigations, replenish our soils, and even become a source of energy, precious metals, and clean drinking water. New methods to make better use of our sewage can also help reduce pollution and greenhouse-gas emissions. Poop can help heal our planet. Nelson dives into the science of scat and profiles several examples of how people are using poop in new and innovative ways. Wide ranging and deeply informed, with a wry sense of humor, this is a solid recommendation for fans of Mary Roach, as well as anyone interested in out-of-the-box ideas to help fix some of our most pressing problems.
