HUNTINGDON and the surrounding villages could coalesce into a single conurbation unless curbs are placed on development, countryside campaigners believe. The Campaign to Protect Rural England fears the district is coming under intolerable pressure from central government to accept extra homes - at least 11,200 between 2001 and 2021 - and wants a public debate to assess people's priorities. Its comments coincide with publication of a new study showing that more than half of Cambridgeshire is now either built on or affected by noise and light pollution. CPRE says the East of England, once quieter with broad stretches of undisturbed countryside, is now the third most disturbed region. At the current rate of loss of tranquil countryside, the entire region could be blighted in 70 years, the campaigners say.
