[Air-L] searching for examples of online citizens engagement in environmental controversies

Dear AIR-listers, I am a Phd student in Multimedia Communication at the University of Udine (Italy) interested in studying citizen engagement in environmental controversies, especially when online tools are somehow involved in the participatory processes. Could you maybe suggest me some interesting study cases I can have look at? If any of you is interested in discussing those issues, please write to me at kitamani82@hotmail.com Thank you in advance for your assistance! Federica
