When a mermaid turns fifteen, she is permitted to swim to the surface for the first time to glimpse the world above, and when the sisters become old enough, each of them visits the upper world one at a time every year."
However, come her time to visit the surface, the Little Mermaid is appalled to find her various sea creature companions sick from the black oil that destroys their ocean. While tending to the birds, fishes and other animals, the Little Mermaid becomes disillusioned by humankind and the oil that is destroying her home.
