When a tree falls in the forest and no one is there, does it make a sound? Could that sound be the cheering of protestors or the crackling of fires? If a Tree Falls directed by Marshall Curry is a documentary that investigates the activities and history of the Environmental Liberation Front (E.L.F.) with Daniel McGowan as the medium. This thought provoking film makes us all gasp as our views on the environmental protection shifts from side to side in the rocky waters of truth. For me at least, this film not only highlights the E.L.F.’s troubles, but also echos the same frustrations many activists have felt in their own fields.
