Press taking footage of chimney during Greenpeace protest against acid rain. Denmark.

Teams of Belgium, West Germany, Austria, UK, Denmark, Netherlands, France and Czechoslovakia simultaneously climbed smokestacks in each country. On each stack a banner with a single letter on it so that a composite photograph of all of the smokestacks would show the banners saying "STOP". Action against atmospheric pollution causing acid rain. Photos: Tony Marriner; Denmark action team/campaigners communicating with climbers; Danish climbing team unfolding banner on chimney.
