Green Belt protection needed says naturalist Ray Mears

Green Belts are the Britain's 'greatest unofficial national parks" which need to be cherished and valued, said the naturalist Ray Mears.

He said they were designed to prevent urban sprawl, make the air healthier and cities happier places to live. The survival expert added the UK has been asked to sign up to the concept of a Big Society and this was an opportunity for politicians to act.

Mr Mears will debate this film on Wednesday's Daily Politics on BBC Two, and the discussion will be on iPlayer for seven days after transmission.
