Norfolk North Sea

At this time of year, much of the UK’s wildlife is battling just to survive the cold winter months. But along the north Norfolk coastline, during the harshest of seasons, one marine mammal is bringing new life to these windswept shores - the grey seal.\n\nAnita Rani and Matt Baker head to Blakeney National Nature Reserve, a four-mile-long shingle spit that offers protection and provides a perfect habitat for seals to come ashore and breed. Anita joins the beach warden on his rounds, as they count the seal population and ensure the numbers indicate a healthy population. Anita then lends a hand at a nearby seal rescue centre where it’s feeding time.\n\nMatt finds a spot on the coast with a local artist capturing the wildlife along the shores, and there's a look at the volunteers who patrol the beaches, moving seals out of harm's way and informing the public about how to keep the seals safe. And Charlotte looks at air pollution and how farming plays a part in creating some of the harmful emissions we breathe in.
