Two partisan views of a controversial issue. The Mersey Barrage
Laurie Taylor presents two films made from deeply opposed positions.
Backed by Government money and private business, there is a scheme to build a barrage across the River
Mersey, to harness tidal power and create electricity. Excited by the prospect of clean, pollution-free energy, Graham Davies , a local teacher, argues the case in favour of the barrage, seeing it as the key to the economic revival of Merseyside.
The case against the barrage is put in an evocative film made with The Merseyside Naturalists Association. They foresee enormous damage being done to the shoreline, the fishing industry and, above all, the incomparable bird-life of the region. In the words of naturalist Eric Hardy , the barrage could spell 'ecological disaster'.
Both films have been made with the help of the BBC
