Julia Bradbury and Adam Henson head to Somerset to find out why the Quantock Hills were the first place in England to be declared an area of outstanding natural beauty.

Adam also lends a hand with the ponies that run wild on the hills while Julia witnesses one of winter's greatest wildlife spectacles - roosting starlings.

Meanwhile Matt Baker heads north to meet the farmer who is providing willow to feed hungry giraffes at Chester Zoo and James Wong gets the lowdown on how we produce one of our 'superfoods' - watercress.

John Craven asks why the cost of our weekly shop is at it's highest ever and meets those with real concerns about food security in the future.
