The disappearance

The Gulf of Mexico suddenly ran into the Atlantic
left oil rigs high and dry.
Naturally, the USA claimed the land which was disputed
by Mexico and Cuba and Belize.
What was left of the gulf had rivers and lakes
and as the land greened it turned out to be fertile and
the Amish people encouraged to farm the land which they
did with earnest enthusiasm.
Village sprang up, roads were built, and the famous
veterinarian Jan Pol opened up his practice as well.
As years went by, people forgot that they were farming
on what has been the bottom of a sea.
The sea had not forgotten.
Slowly seeping in and those who had built luxury houses
were the first to leave, but the fishery thrived and
the shrimp business had a revival.
There was a mass exodus, and the Amish people went
back farming the land they knew.
When the water had claimed, all of the gulf and people
forgetting. There was only Wikipedia left to give
a brief outline of the past.
