    Protecting Endangered Soils


    Do Soils Need Our Protection?
    by Ronald Amundson
    A pedologist in California explains why the loss of undisturbed soils should be of concern to all earth scientists. The world's largest depositional basins, where Earth's Quaternary history is most complete, are enticing to urban developers and agricultural interests as well. Unlike living species, undisturbed soils do not reproduce nor can they be recreated.

    Earth Data for the Future
    by Bruce Quirk and Ronald E. Beck
    Since its creation in 1971, the EROS Data Center has received, processed, and distributed Landsat data to a worldwide community of users. A new generation of satellites, to be launched later this year, will soon provide geoscientists and other users with increasingly sophisticated and detailed images of Earth.

    The Florida Water Wars: A Geologic Perspective
    by Mark T. Stewart
    A geology professor at the University of South Florida-Tampa describes the conflicts created when withdrawals of groundwater for municipal use threaten the health of nearby lakes and wetlands. Geologic conditions are the source of the conflict, he explains, and are critical to a successful resolution.
