***** To join INSNA, visit http://www.insna.org ***** Re:Dendrology: The community of trees Interesting study. I have seen/heard this argument in the Avator (2009), a science fiction movie, by a scientific in an effort to stop the distruction of jungle (by humans) in a Alien world (Pandora) (I'm sure most of us watched that movie). I'm just wondering that how the writer/director of the movie knew (or Perhaps imagined) something that is being discovered 7 years later? Or is it that the author took inspirations from the movie?
