Kelvin Boot explores how plants, animals and sand habitats around Britain could benefit from the proposed new Marine and Coastal Access Bill. The Bill promises the public the chance to walk around the coasts of England, Wales and Scotland. Kelvin assesses the potential impact on wildlife and explores the crumbling Dorset Heritage Coast, where the Bill will offer solutions to the problems of coastal erosion. He also hears from landowners and conservationists about the advantages and possible drawbacks for wildlife along the route.
