A broad set of practices typified by radical actions and/or violence in the name of environmental protection.
Eco-terrorism refers to acts of violence ostensibly committed in support of ecological or environmental causes, against persons or their property.
Eco-terrorism is defined by the Federal Bureau of Investigation as "the use or threatened use of violence of a criminal nature against people or property by an environmentally oriented, subnational group for environmental-political reasons, or aimed at an audience beyond the target, often of a symbolic nature." The FBI credited eco-terrorists with 200 million dollars in property damage between 2003 and 2008, and a majority of states within the USA have introduced laws aimed at eco-terrorism.
