Julia Bradbury and Matt Baker head to the Isle of Wight, home to the largest sailing regatta in the world. They take to the water to find out why the Solent is such a magnet for sailors, before heading inland to discover what is being done to protect the island's colony of red squirrels. John Craven investigates whether planning laws are out of date when it comes to evicting travellers from greenbelt land and, down on the farm, Adam Henson tries to decide whether he is better off farming for food, or for environmental grants. Plus Katie Knapman visits Ironbridge to find out why this tiny corner of the Shropshire countryside became the birthplace of the Industrial Revolution 300 years ago.
