Book Description
A page-turning novel that is also an exploration of the great philosophical concepts of Western thought, Jostein Gaarder's Sophie's World has fired the imagination of readers all over the world, with more than twenty million copies in print. One day fourteen-year-old Sophie Amundsen comes home from school to find in her mailbox two notes, with one question on each: "Who are you?" and "Where does the world come from?" From that irresistible beginning, Sophie becomes obsessed with questions that take her far beyond what she knows of her Norwegian village. Through those letters, she enrolls in a kind of correspondence course, covering Socrates to Sartre, with a mysterious philosopher, while receiving letters addressed to another girl. Who is Hilde? And why does her mail keep turning up? To unravel this riddle, Sophie must use the philosophy she is learning—but the truth turns out to be far more complicated than she could have imagined.

This open access book describes the serious threat of invasive species to native ecosystems. Invasive species have caused and will continue to cause enormous ecological and economic damage with ever increasing world trade. This multi-disciplinary book, written by over 100 national experts, presents the latest research on a wide range of natural science and social science fields that explore the ecology, impacts, and practical tools for management of invasive species. It covers species of all taxonomic groups from insects and pathogens, to plants, vertebrates, and aquatic organisms that impact a diversity of habitats in forests, rangelands and grasslands of the United States. It is well-illustrated, provides summaries of the most important invasive species and issues impacting all regions of the country, and includes a comprehensive primary reference list for each topic. This scientific synthesis provides the cultural, economic, scientific and social context for addressing environmental challenges posed by invasive species and will be a valuable resource for scholars, policy makers, natural resource managers and practitioners.

Book Description
Tourism is the world's largest industry, and ecotourism is rapidly emerging as its fastest growing segment. As interest in nature travel increases, so does concern for conservation of the environment and the well-being of local peoples and cultures. Appalachia seems an ideal destination for ecotourists, with its rugged mountains, uniquely diverse forests, wild rivers, and lively arts culture. And ecotourism promises much for the region: protecting the environment while bringing income to disadvantaged communities. But can these promises be kept? Ecotourism in Appalachia examines both the potential and the threats that tourism holds for Central Appalachia. The authors draw lessons from destinations that have suffered from the "tourist trap syndrome," including Nepal and Hawaii. They conclude that only carefully regulated and locally controlled tourism can play a positive role in Appalachia's economic development.
