There are academic and semantic difficulties in defining "terrorism" and specifically "environmental terrorism", but discussions of environmental
terrorism are growing with a focus on identifying possible risks to
natural resources or environmental features. Some, including in the military argue that attacks on natural resources can now cause more deaths, property damage, political chaos, and other adverse effects than in previous years. Chalecki distinguishes between environmental terrorism and
eco-terrorism. She notes that environmental terrorism can be defined "as the unlawful use of force against in situ environmental resources so as to deprive populations of their benefit(s) and/or destroy other property". In contrast, eco-terrorism is the destruction of property in the interest of saving the environment from human encroachment and destruction. More concisely, environmental terrorism involves targeting natural resources. Eco-terrorism involves targeting the built environment such as roads, buildings and trucks, in defense of natural resources. Other analysts may fail to distinguish between these different threats. == Examples ==
