Eco-terrorism has already been a thing. Creepy loner Ted Kaczynski killed three complete strangers and maimed 23 more. The only way that he got away with his reign of terror for so long was that he lived in a cabin in the middle of nowhere and grew his food in his own shit. He had no telephone and no electricity, and no woman and no friends. The only reason that he was captured was because his brother recognized the writing in his manifesto.

The only way that an eco-terrorist group could get away with anything would be to first throw away their smartphones before they even had a meeting. The kidnapping of groups of people would make them inhuman scumbags in the league of the Chechen terrorists and Boko Haram, wouldn't it? They better not be expecting any mercy when they are caught.
