Planet Under Pressure: Acid Assault

Canada, 1991 (MIFF 1992, Science Film Programme)

Director: D. Chamberlain, V. Goetzelman

In 1977 Canadian scientists decided to sacrifice one lake to study the effect of acid rain on the thousands of lakes spread across North America. Each year measured amounts of raw acid were dumped into the lake, leading to a rapid depletion of species at all levels of the food chain. Within seven years all that remained was crystal clear water, devoid of life. This film for school students educates us all about the critical problem of acid rain.
