For this prediction, an eco-terrorism attack is defined as a violent act carried out with the primary intent of promoting environmentalist objectives. This question aims to predict if such an attack leading to the death of more than ten people will occur before the end of December 31, 2034.

The act should either be publicly declared as eco-terrorism by the individuals or group responsible, or it should be designated as such by a recognized authority. A "significant loss of life" is specified as the immediate or within one month demise of more than ten individuals directly impacted by the attack.

The location of the act is not restricted, meaning it can occur anywhere in the world. At least two news agencies with a solid reputation for factual reporting must confirm the incident. If no such event takes place by the end of the specified date, the market will resolve as 'No'. However, the resolution can happen at an earlier time if an attack fitting the defined criteria occurs sooner.
