It, it is a serious problem, I mean the area at the moment between east of Saltdean, erm Telscombe Cliffs, erm through to the east end of Peacehaven, is in the process of being protected by a seawall and an undercliff walk, rather like the area from erm Black Rock in Brighton through to Saltdean, because the rate of retreat of the cliffs there was so great erm that it would very shortly be threatening the houses on the clifftop at Peacehaven, so that erm a lot of money's having to be spent to stop the erosion of the cliffs along that stretch.
