Just how protected are our coastlines? A report from the National Trust has warned that more than 70% of our coastline in Wales could be affected by coastal erosion or flooding in the next 100 years.

It might seem insignifant to those living in larger towns, but it'll strike terror into the hearts of people living in little coastal villages across the country.

We travel from the village of Porth Dinllaen on the Llyn Peninsula to the northern tip of Anglesey to see the effects and explore what should be done.
