Radical environmentalism and its progeny, "eco-terrorism", is a modern phenomenon. It is a movement far removed from the elite conservationists of the late 1800s and the mainstream environmental groups that emerged later. Disaffected environmentalists have turned from political lobbying to direct action in the form of widespread property destruction and other types of crime and terror. Here, the author exposes the activities of radical groups determined to make their mark in the movement to protect the earth and its creatures from those they view as predators. He covers the major groups as well as less well-known ones and provides portraits of who they are and what they do. The growth of eco-terror from the 1980s to the present day is noticeable and significant. Terror groups have caused millions of dollars worth of damage, and have committed more than 600 criminal acts in the United States alone since 1996. This book takes an objective look at the most radical groups and their terrorist activities in the U.S. It includes case examples and analysis of the methods and rhetoric employed by these groups. It uncovers the losses both to individuals and the community as a result of these methods, and it describes the ideologies, motivations, history, and activities of the political movements that have been labelled as environmental terrorism.
