Soil contamination...public lands...surface and groundwater pollution...coastal erosion...global warming. Have we reached the limits of this planet's ability to provide for us? If so, what can we do about it? These vital questions are addressed by Jill Schneiderman in The Earth Around Us, a unique collection of thirty-one essays by a diverse array of today's foremost scientist-writers. Sharing an ability to communicate science in a clear and engaging fashion, the contributors explore Earth's history and processes--especially in relation to today's environmental issues--and show how we, as members of a global community, can help maintain a livable planet. The narratives in this collection are organized into seven parts that describe: - Earth's time and history and the place of people in it - Views of nature and the ethics behind our conduct on Earth - Resources for the twenty-first century, such as public lands, healthy forests and soils, clean ground and surface waters, and fluctuating coastlines - Ill-informed local manipulations of landscapes across the United States - Innovative solutions to environmental problems that arise from knowledge of the interactions between living things and the Earth's air, water, and soil - Natural and human-induced global scale perturbations to the earth system - Our responsibility to people and all other organisms that live on Earth Never before has such a widely experienced group of prominent earth scientists been brought together to help readers understand how earth systems function to produce our physical and biological environment. Driven by the belief that earth science is, and should be, an integral part of everyday life, The Earth Around Us empowers all of us to play a more educated and active part in the search for a sustainable future for people and other living things on our planet.

"One of the world's great karstic aquifer systems, the Edwards aquifer system supplies water for more than 2 million people and for agricultural, municipal, industrial, and recreational uses. This volume reviews the current state of knowledge, current and emerging challenges to wise use of the aquifer system, and some technologies that must be adopted to address these challenges"--
The story of Fort Clark and Brackettville began with a quiet pool of water, Las Moras Spring, named by the Spanish conquistadors for the mulberry trees lining its banks. The discovery of gold in California and the Treaty of Guadalupe Hidalgo precipitated the opening of the Lower Road from San Antonio to El Paso. To protect the spring and the travelers on the road, the U.S. government established a fort on the high ground above the spring. The town of Brackettville grew with the fort, and the area soon played host to an honor roll of American heroes. ÝÝRevealed in some 200 images, many never before published, are some of the fortís most famous alumni, including Stuart, Longstreet, Sheridan, Sherman, Bullis, Patton, and Wainwright, in addition to the little-known Medal of Honor recipients buried there. Captured here are the deeds of a legion of unsung heroes, as well as the fort and townís historic past, highlighting the Indian War era, the Seminole Scouts, and the quiet time between the World Wars. Culled from the collections of the Library of Congress, the National Archives of the U.S. Army Signal Corps, and pioneer photographer Eugene O. Goldbeck, this book is a testament to American soldiers throughout the country.
