There are a number of lost villages, long-since drowned, off the coast of Norfolk and Suffolk. For some reason I find this fact fascinating.
And the process is ongoing, even accelerating. More coastal settlements are continuing to fall into the sea. Apparently it's a combination of multiple factors. Southern Britain sinking and Scotland rising, as a consequence of the loss of the glaciers of the ice-age, causing a kind of 'bounce-back' of the northern part of the island, no longer weighed down by all that ice, plus climate change and rising sea-levels, plus there's the fact that most of that area is basically just sand banks, and very easily eroded.
The demands of some locals for more coastal protection seems a bit futile to me, like literal King Cnute stuff, given that I gather it's been ongoing since at least the days when Doggerland disappeared beneath the North Sea (now _that_ was a real Brexit).
What I don't understand is where the eroded land is going. Presumably for every part of the coastline that erodes away some other stretch of coast gains land?
Does it cancel out across the British mainland, or is Britain gradually disappearing, as our land is slowly appropriated by those dastardly EUniks?
