Another film recommendation. National Geographic photographer James Balog set out to complete his "Extreme Ice Survey" and his film was presented at the Sundance film festival in 2012. He set up over 50 cameras in 3 continents to measure the retreat of the world's glaciers. After all of the camera's failed he had to set them up all over again. The time-lapse photography records the deaths of this giant glaciers. He also has done a TED talk worth watching. "Chasing Ice" was on Netflix for a while. Mandatory watching for anyone who cares about this planet.
