This is probably the best overall documentary I’ve seen about the environment; it is uncompromisingly militant and very entertaining to boot. It is available in 9 parts on You Tube. Here’s part 1. I cannot more highly recommend it.
I’ve also transcribed the video in English, in case anybody wants to subtitle it in their native language; I did this for a friend in the Czech Republic and he then added subtitles and showed it at hardcore shows! Let me know if you want a copy of the transcript.
