Adam Henson and Ellie Harrison visit Dorset to explore a stretch of coastline which tells us much about the history of life on earth. Often called The Jurassic Coast, the crumbling cliffs of Dorset reveal fossils dating back millions of years.

And there are also more hidden gems under the water off the Dorset coast: rare seahorses. At this time of year, the males are about to give birth, as Ellie finds out when she dives down to see them.

John Craven is in Herefordshire to investigate the effect of music festivals on our countryside. Who cleans up the mess after the bands and their fans have packed their backs and headed back to the city?

Also James Wong meets the man who's determined to save our wild flower meadows.
