CInspired by Helen Czerski's new book, "Blue Machine", I envisaged the sea as a big blue engine – an immense, indomitable force that relentlessly powers our existence. It stores vast amounts of energy and plays a vital role in climate regulation and economies. Without this omnipotent 'blue engine', events like the Tall Ships race would simply not exist.

In the illustration, the undersea world is the planet's largest, unseen engine, tirelessly operating round-the-clock supporting diverse ecosystems. It serves as a reminder that we must care for this essential powerhouse and never diminish its substantial impact on our planet.
