It is the future. Many coastal ports have already been severely damaged.
Fish are increasingly scarce everywhere.
The west coast shellfish industry has long since disappeared. Hundreds of once plentiful marine and wetlands dependent species now extinct. Bluefish, Tuna, mackerel and some deep sea species still exist, but only far north of their usual fishing grounds. Any fishing which still exists is dependent on deep sea species migrating up from the tropics, and these are mostly caught for starving Asian countries. Once settled portions of Hawaii have also disappeared under the waves, and Hawaiian ports are seriously threatened.
