The Wildlife Trusts (Inc. Cornish Wildlife Trust) have set up an animated online petition to fight against the scallop dredging and other destructive forms of fishing to save the reefs of Lyme Bay, off the coast of Dorset/Devon. The campaign is to try and get protection of the reefs - 60 square miles (a total 10% of the entire bay) People have been campaigning to protect Lyme Bay for the past 16 years.
