Every time we sneeze, there seems to be a new form of flu: bird flu, swine flu, Spanish flu, Hong Kong flu, H5N1, and most recently, H5N7. While these diseases appear to emerge from thin air, in fact, human activity is driving them. And the problem is not just flu, but a series of rapidly evolving and dangerous modern plagues. According to veterinarian and journalist Mark Walters, we are contributing to, if not overtly causing, some of the scariest epidemics of our time. Through human stories and cutting-edge science, Walters explores the origins of seven diseases: Mad Cow Disease, HIV/AIDS, Salmonella DT104, Lyme Disease, Hantavirus, West Nile, and new strains of flu. He shows that they originate from manipulation of the environment, from emitting carbon and clear-cutting forests to feeding naturally herbivorous cows "recycled animal protein." Readers will both learn how today's plagues first developed and discover patterns that could help prevent the diseases of tomorrow.

A portrait of a species on the brinkThe only bird species that lives exclusively in Florida, the Florida Scrub-Jay was once common across the peninsula. But as development over the last 100 years reduced the habitat on which the bird depends from 39 counties to three, the species became endangered. With a writer's eye and an explorer's spirit, Mark Walters travels the state to report on the natural history and current predicament of Florida's flagship bird.Tracing the millions of years of evolution and migration that led to the development of songbirds and this unique species of jay, Walters describes the Florida bird's long, graceful tail, its hues that blend from one to the next, and its notoriously friendly manner. He then focuses on the massive land-reclamation and canal-building projects of the twentieth century that ate away at the ancient oak scrub heartlands where the bird was abundant, reducing its population by 90 percent.Walters also investigates conservation efforts taking place today. On a series of field excursions, he introduces the people who are leading the charge to save the bird from extinction—those who gather for annual counts of the species in fragmented and overlooked areas of scrub; those who relocate populations of Scrub-Jays out of harm's way; those who survey and purchase land to create wildlife refuges; and those who advocate for the prescribed fires that keep scrub ecosystems inhabitable for the species.A loving portrayal of a very special bird, Florida Scrub-Jay is also a thoughtful reflection on the ethical and emotional weight of protecting a species in an age of catastrophe. Now is the time to act, says Walters, or we will lose the Scrub-Jay forever.
