Bronze sculptures have long been used to capture the beauty and fragility of marine ecosystems, serving as powerful symbols for ocean conservation. Among the most notable projects is Jason deCaires Taylor’s "The Rising Tide," a series of submerged bronze figures in London’s Thames River, depicting horsemen and children to raise awareness about climate change. Another striking example is "Ocean Atlas" by Jason deCaires Taylor in the Bahamas, the largest underwater sculpture in the world, showcasing a young girl holding up the ocean to symbolize human responsibility.

In Australia, "The Coral Greenhouse" by the same artist features bronze sculptures of scientists and children, designed to promote reef restoration. Meanwhile, "The Mermaid" by Edvard Eriksen in Copenhagen, though not explicitly conservation-themed, has inspired many ocean-themed artworks. These projects not only celebrate marine life but also urge viewers to reflect on humanity’s impact on the oceans, blending art with environmental advocacy.
