The oceans are the circulatory system of our planet, regulating the climate and harboring most of Earth's biodiversity. However, our relationship with the waters has been of exploitation and neglect.

Poetically, the sea is the mirror of the sky, a blue abyss that keeps the secrets of the origin of life.
