It may seem counter intuitive to get in touch with nature by watching movies about it. But a movie can lead to powerful changes in attitudes or behavior. Environmental advocates would say such changes are urgently needed to sustain human life long term.

One draws together a sampling of environmental films made over the last year or so augmented by in-person discussions and the other sounds the climate change alarm with Boston-area experts on both sides of the camera.
