Mary Roach's Fuzz: When Nature Breaks the Law investigates human-wildlife conflict through encounters with bears in Yosemite, elephants in India, cougars in Colorado, and 'danger trees' in California. Roach, known for Stiff, Bonk, and other books that bring her curious, irreverent voice to unusual topics, travels the world with wildlife managers, forensic specialists, and conservation officers. She reveals that in these conflicts, humans are often the problem, through poor food storage, habitat encroachment, or counterproductive policies, and humans must be the solution. Roach writes about vasectomies for deer, bear-proof trash cans, and the challenges of prosecuting crimes committed by animals (an issue that stretches back to medieval trials of pigs). Her humor is balanced by genuine engagement with the ethical and practical difficulties of living alongside wild animals. Roach respects the experts she profiles and learns from their hard-won knowledge. Fuzz is accessible and entertaining while conveying serious research about conservation, wildlife management, and human-animal relations. Essential reading for anyone interested in how we share the planet with other species, told by a writer with a gift for making science fun.
