Historically, targeting oil lords makes them all kill-y. These days at best, if you're in a Western democracy country, you'd probably be blacklisted and buried to whatever extent possible.

Unfortunately making a ruckus among us is probably one of the most effective options, and if they believe their, and all our, lives are on the line I'm thankful it's at least this sort of thing.

Historically, nothing to lose mentalities for existential causes don't go well either. Shit, less on the line in the 70s and there were the bombing type of eco-terrorism. I'm honestly surprised we haven't hit that, but maybe it's just less lead in the air...
