Matt Baker and Margherita Taylor are in Dorset, on the stunning Isle of Purbeck, looking at the importance of its diverse landscape and the changes the coastline has gone through over the centuries. Matt goes on safari to look at the wildlife that call this habitat home, and Margherita discovers what used to live along these shores millions of years ago . We catch up with Dwayne Fields and his gallant team of explorers on the second part of their Snowdonia adventure, and Tom Heap investigates the damage that is being caused to the countryside and coast by an influx of visitors and holidaymakers.
