When Nature Breaks the Law
by Mary Roach
Join "America's funniest science writer" (Peter Carlson, Washington Post), Mary Roach, on an irresistible investigation into the unpredictable world where wildlife and humans meet.
What's to be done about a jaywalking moose? A bear caught breaking and entering? A murderous tree? Three hundred years ago, animals that broke the law would be assigned legal representation and put on trial. These days, as New York Times best-selling author Mary Roach discovers, the answers are best found not in jurisprudence but in science: the curious science of human-wildlife conflict, a discipline at the crossroads of human behavior and wildlife biology.
Roach tags along with animal-attack forensics investigators, human-elephant conflict specialists, bear managers, and "danger tree" faller blasters. Intrepid as ever, she travels from leopard-terrorized hamlets in the Indian Himalaya to St. Peter's Square in the early hours before the pope arrives for Easter Mass, when vandal gulls swoop in to destroy the elaborate floral display. She taste-tests rat bait, learns how to install a vulture effigy, and gets mugged by a macaque.
Combining little-known forensic science and conservation genetics with a motley cast of laser scarecrows, langur impersonators, and trespassing squirrels, Roach reveals as much about humanity as about nature's lawbreakers. When it comes to "problem" wildlife, she finds, humans are more often the problem―and the solution. Fascinating, witty, and humane, Fuzz offers hope for compassionate coexistence in our ever-expanding human habitat.

"Bestseller Roach sheds light on nature's malefactors in this often funny, always provocative survey of species that 'regularly commit acts that put them at odds with humans'...This eminently entertaining outing is another winner for Roach." - Publishers Weekly (starred review)
"Roach joyfully explores how human culture and wildlife, including plant life, have either found ways to coexist or are constantly at odds...From the terrifying to the frustrating, a great starting point for understanding the animal world." - Kirkus Reviews (starred review)
"A must-read for wildlife enthusiasts, popular science readers, and anyone who has enjoyed Roach's other books. Her occasionally awkward interactions with people and animals make for the engaging narrative style that Roach is famous for." - Library Journal (starred review)
"Hilarious! With Fuzz, Mary Roach again takes us into an unfamiliar scientific realm, in this case the science of managing the conflicts between humans and the natural world―lethal leopards, rampaging elephants, jet-downing birds, even killer trees. It's an ever-widening conflict zone, but one that Ms. Roach gleefully mines for a multitude of bizarre facts that'll make you snort coffee through your nose." - Erik Larson, bestselling author of The Splendid and the Vile
