ocean of yesteryear

The development of ocean energy has accelerated the transition of earth civilization,
Part of the ocean has been degraded into a sea of ​​sand,
Rock formations, reefs, animal carcasses on the ocean floor,
Gradually accumulated and weathered into strange buildings,
Except for the ocean,
And forests, rivers, plains, meadows,
In the process of crazy development of civilization,
Abandoned by human beings one by one.
