You might be interested in this campaign I've come across. They're trying to make the destruction of ecosystems a crime - ecocide - like genocide. If the proposal gets enough votes, it gets to be considered by the European Parliament. Have a look: [http://www.endecocide.eu/]
Interesting debate. No protests probably don't work to effect direct change but they do raise awareness so the majority can do the things that definitely work...switching power suppliers to green energy for example.
I have started a group Mums against fracking check out my fb page if you want to do something about the planned ecocide that will happen before any law can be passed!
