Militant Environmentalists (Patreon)

I wonder what would happen if a large group of militant environmentalists decided to punish all of the evil planet killers (whatever they decided that meant).  If there were enough of them (and the loss of farming land in Asia due to ocean rise could displace millions or even billions), they could topple governments even Western governments.  Now if there were technology to make cyborgs or do transformations available, I wonder what they would inflict on the  EPKs?
