Book Description
Thousands of ravenous tiny shorebirds race along the water’s edge of Delaware Bay, feasting on pin-sized horseshoe-crab eggs. Fueled by millions of eggs, the migrating red knots fly on. When they arrive at last in their arctic breeding grounds, they will have completed a near-miraculous 9,000-mile journey that began in Tierra del Fuego. Deborah Cramer followed these knots, whose numbers have declined by 75 percent, on their extraordinary odyssey from one end of the earth to the other—from an isolated beach at the tip of South America all the way to the icy tundra. In her firsthand account, she explores how diminishing a single stopover can compromise the birds' entire journey, and how the loss of horseshoe crabs—ancient animals that come ashore but once a year—threatens not only the survival of red knots but also human well-being: the unparalleled ability of horseshoe-crab blood to detect harmful bacteria in vaccines, medical devices, and intravenous drugs safeguards human health. Cramer offers unique insight into how, on an increasingly fragile and congested shore, the lives of red knots, horseshoe crabs, and humans are intertwined. She eloquently portrays the tenacity of small birds and the courage of many people who, bird by bird and beach by beach, keep red knots flying.
Nature's Entrepot

Pages : 376
Book Description
In Nature's Entrepot, the contributors view the planning, expansion, and sustainability of the urban environment of Philadelphia from its inception to the present. The chapters explore the history of the city, its natural resources, and the early naturalists who would influence future environmental policy. They then follow Philadelphia's growing struggles with disease, sanitation, pollution, sewerage, transportation, population growth and decline, and other byproducts of urban expansion. Later chapters examine efforts in the modern era to preserve animal populations, self-sustaining food supplies, functional landscapes and urban planning, and environmental activism. Philadelphia's place as an early seat of government and major American metropolis has been well documented by leading historians. Now, Nature's Entrepot looks particularly to the human impact on this unique urban environment, examining its long history of industrial and infrastructure development, policy changes, environmental consciousness, and sustainability efforts that would come to influence not just this region but also the nation.
