i think eco terrorism will be mostly focused sabotage. all eco terrorist need to do is stop production of refined goods, supply line being global, sabotaging some unprotected factory in bangladesh that is the only one that produces a specific component could stop production of some given product globally.

That is certainly a worthwhile concern.

Edit to be clear: I think it is a worthwhile concern, not a reason to condemn all ecoterrorist action. It is just important that such action be well planned.

I think it pales in risk comparison to stuff like regular war though, and that keeps happening. They blow shit up for maximum impact and effect. whereas I would hope ecoterrorists are at least motivated to attack stuff in a non-environmentally-destructive way. Or at least, pick targets that have greater positive global impact than local negative impacts, but that kinda thing can't be an easy decision.
