"Nearly 25% of the world's population lives in karst areas -- landscapes that are characterized by sinkholes, caves, and underground drainage. Living with Karst, the 4th booklet in the AGI Environmental Awareness Series, vividly illustrates what karst is and why these resource-rich areas are important. The booklet also discusses karst-related environmental and engineering concerns, guidelines for living with karst, and sources of additional information."--Provided by publisher.

America’s national parks are breathing spaces in a world in which such spaces are steadily disappearing, which is why more than 300 million people visit the parks each year. Now Terry Tempest Williams, the author of the environmental classic Refuge and the beloved memoir When Women Were Birds, returns with The Hour of Land, a literary celebration of our national parks, an exploration of what they mean to us and what we mean to them. From the Grand Tetons in Wyoming to Acadia in Maine to Big Bend in Texas and more, Williams creates a series of lyrical portraits that illuminate the unique grandeur of each place while delving into what it means to shape a landscape with its own evolutionary history into something of our own making. Part memoir, part natural history, and part social critique, The Hour of Land is a meditation and a manifesto on why wild lands matter to the soul of America.
