ECONOMIC- in debt if they ask Japan for 3m sea wall, damages fishing industry and reduces tourist income
ENVIRONMENTAL- loss of beach means no attraction and loss of habitats, soil is 20cm deep so floods prevent crops from growing, damage to coral so fish die
SOCIAL- fresh water supply polluted by salt and people having to leave in 7 years

porlock- managed retreat
in storms the shingle beach was being broken through
farm land was being destroyed which means loss in money for farmers

this created marsh land which enhanced biodiversity and acted as a natural barrier

keyhaven marshes- formation
formed by shingle being deposited in slower moving areas e.g behind spit or bar
pioneer plant called codgrass formed and trapped more sediment
Marsh grass became a habitat to blue butterfly ect- vegetation success

keyhaven marshes- threats
trampling on codgrass from tourists
this can kill animals and habitats e.g. spider
litter can pollute the marsh
construction of groynes to the west of the marsh means less sediment being trapped in codgrass
sea level rise means the plants and animals get submerged beneath water
