There are also environmental crimes being carried out world-wide:

Also in need of severe punishment but unlikely to happen in most cases.
I wouldn't spray-paint Stonehenge myself or throw tomato soup at famous paintings, but I do wonder what people are meant to do to alert the world and their governments to the huge environmental problems facing us today world-wide??
MOO JMO
btw I'm interested in archaeology myself.
