Norfolk County Council today pledged it would fight for Government funding to protect the Broads from flooding.
Natural England and the Broads Authority have discussed plans to abandon coastal defences and allow the Upper Thurne to be flooded by the sea.
The move would mean the end for Horsey Mere, Hickling Broad, Heigham Sound and the Martham broads - along with six coastal villages, internationally-important nature reserves and thousands of hectares of farmland.
Nearly 700 people have signed an online petition, on Gordon Brown's 10 Downing Street website, to save the Broads. Click here to join them.
