Richard Muir explains how the British coastline evolved its diverse scenery; why there are so many rock types; how cliffs, sea caves, blowholes, arches and sea stacks are formed; and why sand and shingle beaches, sandpits and lagoons are created. He describes how the early fishing and limpet-gathering in the Middle Stone Age developed into the present-day fishing industry. He recounts how in the past, efforts have been made to stabilize vulnerable coastlines. These eforts have not prevented disasterous floods. The current causes for concern are oil spillages, the discharge of toxic substances and the over-exploitation of resources and their impact not just on man, but on the wildlife in these areas.
