In my GEO 162 Global Environmental Issues course student view at least one documentary film a week outside of class as part of the curriculum. This past spring we watched the film "Watermark" for the first time. It's from the directors of "Manufactured Landscapes" - I show clips from this film in class as well. Here are a few images from Watermark. I've clipped stills of the more stunning scenes and put them into this Powerpoint file for classroom use. Here are reviews of Watermark on MRQE.
