Overview: Britain’s coastline is defined by the forces of nature: the wind, rain, sun and tides, which influence the lives of every single living thing here. Alan braves the elements to find out why our coastline is such an extraordinary place for wildlife. From the giant minke whale to the tiny snail bee, the elegant Arctic tern to the plodding toad, and the fastest seabird in the west to one of the world’s greatest predators. Danger, spectacle and revelation – it’s all here in Coastal Britain.
