Air!

Air! (1972) is a animation film directed by Paul Driessen rated 7.3/10.

Although only a couple of minutes long, this animated short makes the point that oxygen is the stuff of life whether on land, in the air or water, but that it is becoming scarcer as man-made pollutants crowd it out. This is a film without words in which plants, birds, fish and, finally, man come to the same "breathless" end
