**6. Limitation**

There are a few limitations to this study. This narrative review is an evidence-round up, on ecoterrorism, and not a systematic evidence-based investigation. Although this review may not have the same value as a systematic review, given the fact that the topic is seldom discussed, it still gathers enough information for further studies or a systematic review. Having this in mind, the selection of the literature used might be biased and based on the author's preferences.
