During the Defy Film Festival there was a rolling loop of pre-show entertainment. This isn't uncommon but the custom footage cut together came from a bizarre variety of sources. Once such segment that really caught me was two aliens flying around Earth discussing political and ecological issues that our planet is facing. Thanks to some kind Internet sleuths, it turns out the footage is from a 1974 animation called Freedom 2000. The abstract is exactly as I remembered:

Animation highlighting the environmental problems that arise from industrialization and rapid population growth. Two aliens fly above the Earth in a spaceship and discuss how humans need to balance technological advances with ecological health. Created by Hanna-Barbera.

What I did not realize is that the piece is 20 minutes long, was created by Hanna-Barbera and contains a multitude of different styles. If you've got some time, it's most definitely worth hitting play and soaking in. And, yes, it's on YouTube if you prefer.
