Timely and unsettling essays from an important and beloved writer and conservationist In Erosion, Terry Tempest Williams's fierce, spirited, and magnificent essays are a howl in the desert. She sizes up the continuing assaults on America's public lands and the erosion of our commitment to the open space of democracy. She asks: "How do we find the strength to not look away from all that is breaking our hearts?" We know the elements of erosion: wind, water, and time. They have shaped the spectacular physical landscape of our nation. Here, Williams bravely and brilliantly explores the many forms of erosion we face: of democracy, science, compassion, and trust. She examines the dire cultural and environmental implications of the gutting of Bear Ears National Monument—sacred lands to Native Peoples of the American Southwest; of the undermining of the Endangered Species Act; of the relentless press by the fossil fuel industry that has led to a panorama in which "oil rigs light up the horizon." And she testifies that the climate crisis is not an abstraction, offering as evidence the drought outside her door and, at times, within herself. These essays are Williams's call to action, blazing a way forward through difficult and dispiriting times. We will find new territory—emotional, geographical, communal. The erosion of desert lands exposes the truth of change. What has been weathered, worn, and whittled away is as powerful as what remains. Our undoing is also our becoming. Erosion is a book for this moment, political and spiritual at once, written by one of our greatest naturalists, essayists, and defenders of the environment. She reminds us that beauty is its own form of resistance, and that water can crack stone.

For developing nations, soil erosion is among the most chronic environmental and economic burdens. Vast amounts of topsoil are washed or blown away from arable land only to accumulate in rivers, reservoirs, harbors, and estuaries, thereby creating a double disaster: a vital resource disappears from where it is desperately needed and is deposited where it is equally unwanted. Despite much rhetoric and effort, little has been done to overcome this problem. Vetiver, a little-known tropical grass, offers one practical and inexpensive way to control erosion on a huge scale in both humid and semi-arid regions. Hedges of this deeply rooted species catch and hold back sediments while the stiff foliage acts as a filter that also slows runoff and keeps moisture on site. This book assesses vetiver's promise and limitations and identifies places where this grass can be deployed without undue environmental risk.

This classroom resource provides clear, concise scientific information in an understandable and enjoyable way about water and aquatic life. Spanning the hydrologic cycle from rain to watersheds, aquifers to springs, rivers to estuaries, ample illustrations promote understanding of important concepts and clarify major ideas. Aquatic science is covered comprehensively, with relevant principles of chemistry, physics, geology, geography, ecology, and biology included throughout the text. Emphasizing water sustainability and conservation, the book tells us what we can do personally to conserve for the future and presents job and volunteer opportunities in the hope that some students will pursue careers in aquatic science. Texas Aquatic Science, originally developed as part of a multi-faceted education project for middle and high school students, can also be used at the college level for non-science majors, in the home-school environment, and by anyone who educates kids about nature and water.
