Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.

"Originally commenced as a pastime, and to please a circle of friends alone, success, in any degree, can only be hoped for, because of my vantage ground as an intimate and close friend of Mr. Lincoln, and because, by reason of such intimacy, of the novelty of some of the facts and deductions, and not, in any sense, by reason, but in spite of, its literary style or, rather, the lack thereof."--Preface.

For the past three decades, many history professors have allowed their biases to distort the way America’s past is taught. These intellectuals have searched for instances of racism, sexism, and bigotry in our history while downplaying the greatness of America’s patriots and the achievements of “dead white men.” As a result, more emphasis is placed on Harriet Tubman than on George Washington; more about the internment of Japanese Americans during World War II than about D-Day or Iwo Jima; more on the dangers we faced from Joseph McCarthy than those we faced from Josef Stalin. A Patriot’s History of the United States corrects those doctrinaire biases. In this groundbreaking book, America’s discovery, founding, and development are reexamined with an appreciation for the elements of public virtue, personal liberty, and private property that make this nation uniquely successful. This book offers a long-overdue acknowledgment of America’s true and proud history.
