Coastal erosion is a problem for those who
live near coasts and for marine organisms living along the coast in bays,
estuaries, and shallow waters. We have seen that beaches change with the
seasons, and that tsunamis and storm surges can erode coasts. The loss of beaches due to armoring and sea level rise
results in immense negative impacts, including loss of recreational value,
tourism, marine mammal haul-out area, sandy beach habitat, and buffering
capacity against future bluff erosion.
