 Following the September 11, 2001 attacks several laws were passed increasing the penalty for ecoterrorism, and hearings were held in Congress discussing the activity of groups such as the ELF.To date no one has been killed as a result of an ELF or ALF action since both groups forbid harming human or non-human life.It was then announced in 2003 that ""eco-terrorist"" attacks, known as ""ecotage"", had increased from the ELF, ELA and the ""Environmental Rangers"", another name used by activists when engaging in similar activity.
