The health of shorelines around the world is under threat like never before. We look at efforts being made in the UK to tackle some of the challenges posed by overfishing and climate change. We travel to Yorkshire in northern England to meet the scientists and fishing communities trying to work out how to protect local lobster stocks. And in Devon in south west England we hear how artificial reefs are helping attract fish and crustaceans to a previously barren patch of sea.
