In the 1990s, a new organization opposed the destruction of the natural environment and they called themselves the Earth Liberation Front (ELF). Then in March 2001, the Federal Bureau of Investigation (FBI) considered ELF as being the threat of number one terrorist in our country. Through arson and explosion, they began to bring destruction to laboratories, factories, farms etc, mainly because they believe they are using the earth's natural environment and all living creatures.
There is nothing new about radical environmentalism. In 2001, the Earth Liberation Front - a radical violent environmental group - was explained by the FBI as one of the biggest terrorist threats in the country. From 1970 to 2007 at least 25 countries estimate that you can discover more than 1000 crimes, "REAR" (extreme environmentalist and animal rights) cells, and in the United States alone - mainly vandalism And animal experiment facilities During the past three decades, people have been concerned about the new wave of "ecological terror".
The more radical one is still the Earth Liberation Front (ELF). Founded in the UK in 1992, is active in Canada and the United States, based on its sister organization Animal Liberation Front (ALF), loose cell mix without intensive leadership. Common basic guidelines for destroying companies engaged in logging, energy production, and construction are posted on the ELF website, which is said to be "one of the most active militants" according to the FBI . The physical damage exceeded $ 100 million. Most environmentalists refuse to accept approaches adopted by marginal groups such as ELF. Most people use the media to disseminate information, raise awareness, work within the political process, or adopt peaceful protests and civic disobedience strategies.
