Ecoterrorism is the term used to describe actions taken by individuals or organizations to prevent what may loosely be termed as “environmental change.” This change may be seen as the clear-cutting of forests for wood products or land for housing or the use of genetically modified plants or animals for human consumption. Ecoterrorists are those who are willing to take violent and potentially harmful action in order to prevent these types of changes. Beginning in the 1980s, industrial sabotage such as tree-spiking (the process of inserting metal spikes into trees so that they cannot be cut down by chainsaws) was used to prevent logging— and tree-spiking can seriously injure the loggers who are cutting down such trees.
