Paradise Lost -- Film Description:
"A plea without words, made by artist and animator Evelyn Lambart, for the right of all creatures to a clean, unpolluted environment. With style, color and movement sensitive to the subject, the film shows how birds, butterflies and other woodland creatures succumb to air pollution caused by human inventions."
